They are a + quick method of using the following com2sec, group, + access, and view directive lines. They are not as + efficient either, as groups aren't created so the + tables are possibly larger. In other words: don't + use these if you have complex situations to set up. + + The format of the SOURCE is token is described in + the com2sec directive section below. The OID token + restricts access for that community to everything + below that given OID. + + rouser USER [noauth|auth|priv] [OID] + + rwuser USER [noauth|auth|priv] [OID] + Creates a SNMPv3 USM user in the VACM access + configuration tables. Again, its more efficient + (and powerful) to use the combined com2sec, group, + access, and view directives instead. + + The minimum level of authentication and privacy the + user must use is specified by the first token + (which defaults to "auth"). The OID parameter + restricts access for that user to everything below + the given OID. + + com2sec NAME SOURCE COMMUNITY + This directive specifies the mapping from a + source/community pair to a security name. SOURCE + can be a hostname, a subnet, or the word "default". + A subnet can be specified as IP/MASK or IP/BITS. + The first source/community combination that matches + the incoming packet is selected. + + group NAME MODEL SECURITY + This directive defines the mapping from security- + model/securityname to group. MODEL is one of v1, + v2c, or usm. + + access NAME CONTEXT MODEL LEVEL PREFX READ WRITE NOTIFY + The access directive maps from group/security + model/security level to a view. MODEL is one of + any, v1, v2c, or usm. LEVEL is one of noauth, + auth, or priv. PREFX specifies how CONTEXT should + be matched against the context of the incoming pdu, + either exact or prefix. READ, WRITE and NOTIFY + specifies the view to be used for the corresponding + access. For v1 or v2c access, LEVEL will be + noauth, and CONTEXT will be empty. + + view NAME TYPE SUBTREE [MASK] + The defines the named view. TYPE is either included + or excluded. MASK is a list of hex octets, sepa- + rated by '.' or ':'. The MASK defaults to "ff" if + not specified. + + The reason for the mask is, that it allows you to + control access to one row in a table, in a rela- + tively simple way. As an example, as an ISP you + might consider giving each customer access to his + or her own interface: + + view cust1 included interfaces.ifTable.ifEntry.ifIndex.1 ff.a0 + view cust2 included interfaces.ifTable.ifEntry.ifIndex.2 ff.a0 + + (interfaces.ifTable.ifEntry.ifIndex.1 == .1.3.6.1.2.1.2.2.1.1.1, + ff.a0 == 11111111.10100000. which nicely covers up and including + the row index, but lets the user vary the field of the row) + + VACM Examples: + # sec.name source community + com2sec local localhost private + com2sec mynet 10.10.10.0/24 public + com2sec public default public + + # sec.model sec.name + group mygroup v1 mynet + group mygroup v2c mynet + group mygroup usm mynet + group local v1 local + group local v2c local + group local usm local + group public v1 public + group public v2c public + group public usm public + + # incl/excl subtree mask + view all included .1 80 + view system included system fe + view mib2 included .iso.org.dod.internet.mgmt.mib-2 fc + + # context sec.model sec.level prefix read write notify + access mygroup "" any noauth exact mib2 none none + access public "" any noauth exact system none none + access local "" any noauth exact all all all + + Default VACM model + The default configuration of the agent, as shipped, is functionally + equivalent to the following entries: + com2sec public default public + group public v1 public + group public v2c public + group public usm public + view all included .1 + access public "" any noauth exact all none none + +SNMPv3 CONFIGURATION + engineID STRING + The snmpd agent needs to be configured with an + engineID to be able to respond to SNMPv3 messages. + With this configuration file line, the engineID + will be configured from STRING. The default value + of the engineID is configured with the first IP + address found for the hostname of the machine. + + createUser username (MD5|SHA) authpassphrase [DES] [priv- + passphrase] + This directive should be placed into the "/var/ucd- + snmp"/snmpd.conf file instead of the other normal + locations. The reason is that the information is + read from the file and then the line is removed + (eliminating the storage of the master password for + that user) and replaced with the key that is + derived from it. This key is a localized key, so + that if it is stolen it can not be used to access + other agents. If the password is stolen, however, + it can be. + + MD5 and SHA are the authentication types to use, + but you must have built the package with openssl + installed in order to use SHA. The only privacy + protocol currently supported is DES. If the pri- + vacy passphrase is not specified, it is assumed to + be the same as the authentication passphrase. Note + that the users created will be useless unless they + are also added to the VACM access control tables + described above. + + Warning: the minimum pass phrase length is 8 char- + acters. + + SNMPv3 users can be created at runtime using the + snmpusm command. + + +SETTING SYSTEM INFORMATION + syslocation STRING + + syscontact STRING + + Sets the system location and the system contact for + the agent. This information is reported by the + 'system' table in the mibII tree. + + authtrapenable NUMBER + Setting authtrapenable to 1 enables generation of + authentication failure traps. The default value is + 2 (disable). + + trapcommunity STRING + This defines the default community string to be + used when sending traps. Note that this command + must be used prior to any of the following three + commands that are intended use this community + string. + + trapsink HOST [COMMUNITY [PORT]] + + trap2sink HOST [COMMUNITY [PORT]] + + informsink HOST [COMMUNITY [PORT]] + These commands define the hosts to receive traps + (and/or inform notifications). The daemon sends a + Cold Start trap when it starts up. If enabled, it + also sends traps on authentication failures. Mul- + tiple trapsink, trap2sink and informsink lines may + be specified to specify multiple destinations. Use + trap2sink to send SNMPv2 traps and informsink to + send inform notifications. If COMMUNITY is not + specified, the string from a preceding trapcommu- + nity directive will be used. If PORT is not speci- + fied, the well known SNMP trap port (162) will be + used. + +PASS-THROUGH CONTROL + pass MIBOID EXEC + Passes entire control of MIBOID to the EXEC pro- + gram. The EXEC program is called in one of the + following three ways: + + EXEC -g MIBOID + + EXEC -n MIBOID + + These call lines match to SNMP get and get- + next requests. It is expected that the EXEC + program will take the arguments passed to it + and return the appropriate response through + it's stdout. + + The first line of stdout should be the mib + OID of the returning value. The second line + should be the TYPE of value returned, where + TYPE is one of the text strings: string, + integer, unsigned, objectid, timeticks, + ipaddress, counter, or gauge. The third + line of stdout should be the VALUE corre- + sponding with the returned TYPE. + + For instance, if a script was to return the + value integer value "42" when a request for + .1.3.6.1.4.100 was requested, the script + should return the following 3 lines: + .1.3.6.1.4.100 + integer + 42 + + To indicate that the script is unable to + comply with the request due to an end-of-mib + condition or an invalid request, simple exit + and return no output to stdout at all.

These files may contain any of the directives found in the +DIRECTIVES section below. This file is not required for the agent to +operate and report mib entries. +.SH PLEASE READ FIRST +First, make sure you have read the snmp_config(5) manual page that +describes how the ucd-snmp configuration files operate, where they +are located and how they all work together. +.SH EXTENSIBLE-MIB +.PP +The ucd-snmp SNMP agent reports much of its information through +queries to the 1.3.6.1.4.1.2021 section of the mib tree. Every mib in +this section has the following table entries in it. +.IP ".1 -- index" +This is the table's index numbers for each of the DIRECTIVES listed below. +.IP ".2 -- name" +The name of the given table entry. This should be unique, but is not +required to be. +.IP ".100 -- errorFlag" +This is a flag returning either the integer value 1 or 0 if an error +is detected for this table entry. +.IP ".101 -- errorMsg" +This is a DISPLAY-STRING describing any error triggering the errorFlag above. +.IP ".102 -- errorFix" +If this entry is SNMPset to the integer value of 1 AND the errorFlag +defined above is indeed a 1, a program or script will get executed +with the table entry name from above as the argument. The program to +be executed is configured in the config.h file at compile time. +.SS Directives +.IP "proc NAME" +.IP "proc NAME MAX" +.IP "proc NAME MAX MIN" +.IP +Checks to see if the NAME'd processes are running on the agent's +machine. An error flag (1) and a description message are then passed +to the 1.3.6.1.4.1.2021.2.100 and +1.3.6.1.4.1.2021.2.101 mib tables (respectively) if the +NAME'd program is not found in the process table as reported by "/bin/ps -e". +.IP +If MAX and MIN are not specified, MAX is assumed to be +.B infinity +and MIN is assumed to be 1. +.IP +If MAX is specified but MIN is not specified, MIN is assumed to be 0. +.IP "procfix NAME PROG ARGS" +This registers a command that knows how to fix errors with the given +process NAME. When 1.3.6.1.4.1.2021.2.102 for a given +NAMEd program is set to the integer value of 1, this command will be +called. It defaults to a compiled value set using the PROCFIXCMD +definition in the config.h file. +.IP "exec NAME PROG ARGS" +.IP "exec MIBNUM NAME PROG ARGS" +.IP +If MIBNUM is not specified, the agent executes the named PROG with +arguments of ARGS and returns the exit status and the first line of +the STDOUT output of the PROG program to queries of the +1.3.6.1.4.1.2021.8.100 and +1.3.6.1.4.1.2021.8.101 mib tables (respectively). All +STDOUT output beyond the first line is silently truncated. +.IP +If MIBNUM is specified, it acts as above but returns the exit status +to MIBNUM.100.0 and the entire STDOUT output to the table +MIBNUM.101 in a mib table. In this case, the MIBNUM.101 mib +contains the entire STDOUT output, one mib table entry per line of +output (ie, the first line is output as MIBNUM.101.1, the second +at MIBNUM.101.2, etc...). +.RS +.IP Note: +The MIBNUM must be specified in dotted-integer notation and can +not be specified as ".iso.org.dod.internet..." (should instead be +.1.3.6.1...). +.IP Note: +The agent caches the exit status and STDOUT of the executed program +for 30 seconds after the initial query. This is to increase speed and +maintain consistency of information for consecutive table queries. +The cache can be flushed by a snmp-set request of integer(1) to +1.3.6.1.4.1.2021.100.VERCLEARCACHE. +.RE +.IP "execfix NAME PROG ARGS" +This registers a command that knows how to fix errors with the given +exec or sh NAME. When 1.3.6.1.4.1.2021.8.102 for a +given NAMEd entry is set to the integer value of 1, this command will +be called. It defaults to a compiled value set using the EXECFIXCMD +definition in the config.h file. +.IP "disk PATH" +.IP "disk PATH [ MINSPACE | MINPERCENT% ]" +.IP +Checks the named disks mounted at PATH for available disk space. If +the disk space is less than MINSPACE (kB) if specified or less than +MINPERCENT (%) if a % sign is specified, or DEFDISKMINIMUMSPACE (kB) +if not specified, the associated entry in the +1.3.6.1.4.1.2021.9.100 mib table will be set to (1) and +a descriptive error message will be returned to queries of +1.3.6.1.4.1.2021.9.101. +.IP "load MAX1" +.IP "load MAX1 MAX5" +.IP "load MAX1 MAX5 MAX15" +.IP +Checks the load average of the machine and returns an error flag (1), +and an text-string error message +to queries of 1.3.6.1.4.1.2021.10.100 and +1.3.6.1.4.1.2021.10.101 (respectively) when the +1-minute, 5-minute, or 15-minute averages exceed the associated +maximum values. If any of the MAX1, MAX5, or MAX15 values are +unspecified, they default to a value of DEFMAXLOADAVE. +.IP "file FILE [MAXSIZE]" +Monitors file sizes and makes sure they don't grow beyond a certain +size. MAXSIZE defaults to infinite if not specified, and only +monitors the size without reporting errors about it. +.SS "Errors" +.PP +Any errors in obtaining the above information are reported via the +1.3.6.1.4.1.2021.101.100 flag and the +1.3.6.1.4.1.2021.101.101 text-string description. +.SH SMUX SUB-AGENTS +To enable and SMUX based sub-agent, such as +.IR gated , +use the +.I smuxpeer +configuration entry +.IP "smuxpeer OID PASS" +For +.I gated +a sensible entry might be +.IP ".1.3.6.1.4.1.4.1.3 secret" +.SH ACCESS CONTROL +snmpd supports the View-Based Access Control Model (vacm) +as defined in RFC 2275. +To this end, it recognizes the following keywords in the configuration +file: \fIcom2sec\fR, \fIgroup\fR, \fIaccess\fR, and \fIview\fR as well +as some easier-to-use wrapper directives: \fIrocommunity\fR, +\fIrwcommunity\fR, \fIrouser\fR, \fIrwuser\fR. +.IP "rocommunity COMMUNITY [SOURCE] [OID]" +.IP "rwcommunity COMMUNITY [SOURCE] [OID]" +These create read-only and read-write communities that can be used to +access the agent.

In other words: don't use these if you have complex +situations to set up. +.IP +The format of the SOURCE is token is described in the \fIcom2sec\fR +directive section below. The OID token restricts access for that +community to everything below that given OID. +.IP "rouser USER [noauth|auth|priv] [OID]" +.IP "rwuser USER [noauth|auth|priv] [OID]" +Creates a SNMPv3 USM user in the VACM access configuration tables. +Again, its more efficient (and powerful) to use the combined +\fIcom2sec\fR, \fIgroup\fR, \fIaccess\fR, and \fIview\fR directives instead. +.IP +The minimum level of authentication and privacy the user must use is +specified by the first token (which defaults to "auth"). The OID +parameter restricts access for that user to everything below the given +OID. +.IP "com2sec NAME SOURCE COMMUNITY" +This directive specifies the mapping from a source/community pair to +a security name. SOURCE can be a hostname, a subnet, or the word +\fI"default"\fR. +A subnet can be specified as IP/MASK or IP/BITS. +The first source/community combination that matches the incoming packet +is selected. +.IP "group NAME MODEL SECURITY" +This directive defines the mapping from securitymodel/securityname to group. +MODEL is one of \fIv1\fR, \fIv2c\fR, or \fIusm\fR. +.IP "access NAME CONTEXT MODEL LEVEL PREFX READ WRITE NOTIFY" +The access directive maps from group/security model/security level to +a view. +MODEL is one of \fIany\fR, \fIv1\fR, \fIv2c\fR, or \fIusm\fR. +LEVEL is one of \fInoauth\fR, \fIauth\fR, or \fIpriv\fR. +PREFX specifies how CONTEXT should be matched against the context of +the incoming pdu, either \fIexact\fR or \fIprefix\fR. +READ, WRITE and NOTIFY specifies the view to be used for the corresponding +access. +For v1 or v2c access, LEVEL will be noauth, and CONTEXT will be empty. +.IP "view NAME TYPE SUBTREE [MASK]" +The defines the named view. TYPE is either \fIincluded\fR or \fIexcluded\fR. +MASK is a list of hex octets, separated by '.' or ':'. The MASK +defaults to "ff" if not specified. +.IP +The reason for the mask is, that it allows you to control access to +one row in a table, in a relatively simple way.

With this configuration file line, the +engineID will be configured from STRING. The default value of the +engineID is configured with the first IP address found for the +hostname of the machine. +.IP "createUser username (MD5|SHA) authpassphrase [DES] [privpassphrase]" +This directive should be placed into the +"/var/ucd-snmp"/snmpd.conf file instead of the other normal +locations. The reason is that the information is read from the file +and then the line is removed (eliminating the storage of the master +password for that user) and replaced with the key that is derived from +it. This key is a localized key, so that if it is stolen it can not +be used to access other agents. If the password is stolen, however, +it can be. +.IP +MD5 and SHA are the authentication types to use, but you must have +built the package with openssl installed in order to use SHA. The +only privacy protocol currently supported is DES. If the privacy +passphrase is not specified, it is assumed to be the same as the +authentication passphrase. Note that the users created will be +useless unless they are also added to the VACM access control tables +described above. +.IP +Warning: the minimum pass phrase length is 8 characters. +.IP +SNMPv3 users can be created at runtime using the +.I snmpusm +command. +.IP +.SH SETTING SYSTEM INFORMATION +.IP "syslocation STRING" +.IP "syscontact STRING" +.IP +Sets the system location and the system contact for the agent. This +information is reported by the 'system' table in the mibII tree. +.IP "authtrapenable NUMBER" +Setting authtrapenable to 1 enables generation of authentication failure +traps. The default value is 2 (disable). +.IP "trapcommunity STRING" +This defines the default community string to be used when sending traps. +Note that this command must be used prior to any of the following three +commands that are intended use this community string. +.IP "trapsink HOST [COMMUNITY [PORT]]" +.IP "trap2sink HOST [COMMUNITY [PORT]]" +.IP "informsink HOST [COMMUNITY [PORT]]" +These commands define +the hosts to receive traps (and/or inform notifications).

Multiple \fItrapsink\fR, \fItrap2sink\fR +and \fIinformsink\fR lines may be specified to specify multiple destinations. +Use \fItrap2sink\fR to send SNMPv2 traps and \fIinformsink\fR to send +inform notifications. +If COMMUNITY is not specified, the string from a preceding \fItrapcommunity\fR +directive will be used. If PORT is not specified, the well known SNMP trap +port (162) will be used. +.SH "PASS-THROUGH CONTROL" +.IP "pass MIBOID EXEC" +Passes entire control of MIBOID to the EXEC program. The EXEC program +is called in one of the following three ways: +.RS +.IP "EXEC -g MIBOID" +.IP "EXEC -n MIBOID" +.IP +These call lines match to SNMP get and getnext requests.

The MIB files used to compile the handlers in the agent and to +“drive” the testing (snmpwalk et +al under LINUX) +are those acquired from that same UCD distribution. + + +These are the supported MIBs; all are below mib2 == 1.3.6.1.2.1: + + +system { mib2 1 } +interfaces { mib2 2 } + [ address-translation “at” { mib2 3 } is deprecated ] +ip { mib2 4 } +icmp { mib2 5 } +tcp { mib2 6 } +udp { mib2 7 } + [ exterior gateway protocol “egp” { mib2 8 } not supported ] + [ cmot { mib2 9 } is “historic”, just a placeholder ] +dot3 { mib2 10 7 } == { transmission 7 } “EtherLike MIB” +snmp { mib2 11 } + + +On inclusion of SNMPv3 support packages, the following MIBs are added to the +default set of MIBs enumerated above : + + +snmpEngine { snmpFrameworkMIBObjects 1 } SNMP-FRAMEWORK-MIB, as described in + RFC-2571 for support of SNMPv3 + framework. + +usmStats { usmMIBObjects 1 } SNMP-USER-BASED-SM-MIB, as +usmUser { usmMIBObjects 2 } specified in RFC-2574 for support + of user based security model in + SNMPv3 management domains. + + + + + +Small changes have been made in three areas: + + +Various hardware-specific ethernet drivers. +The generic ethernet device driver. +The OpenBSD TCP/IP networking package. + + +These changes were made in order to export information about the driver and +the network that the SNMP agent must report. The changes were trivial in +the case of the network stack, since it was already SNMP-friendly. The +generic ethernet device driver was re-organized to have an extensive header +file and to add a couple of APIs to extract statistics that the +hardware-specific device drivers keep within themselves. + + +There may be a performance hit for recording that data; disabling +a config option named something like +CYGDBG_DEVS_ETH_xxxx_xxxx_KEEP_STATISTICS +depending on the specific device driver will prevent that. + + +Not all platform ethernet device drivers export complete SNMP statistical +information; if the exported information is missing, SNMP will report zero +values for such data (in the dot3 MIB). + + +The interface chipset has an ID which is an OID; not all the latest greatest +devices are listed in the abailable database, so new chipsets may need to +be added to the client MIB, if not defined in those from UCD. + + + + + +A routine to instantiate and start the SNMP agent thread in the default +configuration is provided in +PACKAGES/net/snmp/agent/VERSION/src/snmptask.c + + +It starts the snmpd thread at priority +CYGPKG_NET_THREAD_PRIORITY+1 +by default, ie. one step less important than the TCP/IP stack service +thread. +It also statically creates and uses a very large stack of around 100 +KiloBytes. +To use that convenience function, this code fragment may be copied (in +plain C). + + +#ifdef CYGPKG_SNMPAGENT +{ + extern void cyg_net_snmp_init(void); + cyg_net_snmp_init(); + +} +#endif + + +In case you need to perform initialization, for example setting up SNMPv3 +security features, when the snmp agent starts and every time it restarts, +you can register a callback function by simply writing the global variable: + +externC void (*snmpd_reinit_function)( void ); + +with a suitable function pointer. + + +The entry point to the SNMP agent is + +externC void snmpd( void (*initfunc)( void ) ); + +so you can of course easily start it in a thread of your choice at another +priority instead if required, after performing whatever other +initialization your SNMP MIBs need. A larger than default stacksize is +required. The initfunc parameter is the callback +function mentioned above — a NULL parameter there is safe and +obviously means no callback is registered. + + +Note that if you call snmpd(); yourself and do +not call cyg_net_snmp_init(); then +that routine, global variable, and the default large stack will not be +used. This is the recommended way control such features from your +application; create and start the thread yourself at the appropriate +moment. + + +Other APIs from the snmpd module are available, +specifically: + +void SnmpdShutDown(int a); + +which causes the snmpd to restart itself — +including the callback to your init function — as soon as possible. + + +The parameter a is ignored. It is there because in +snmpd's “natural environment” this routine +is a UNIX signal handler. + + +The helper functions in the network stack for managing +DHCP +leases will call SnmpdShutDown() +when necessary, for example if network interfaces go down and/or come up +again. + + + + + +To use the SNMP agent, the SNMP library and agent packages must be +included in your configuration. To incorporate the stack into your +configuration select the SNMP library and SNMP agent packages in the +eCos Configuration Tool, or at the command line type: + +$ ecosconfig add snmplib snmpagent + + + +After adding the networking, common ethernet device drivers, +snmp library and snmp agent packages, there is no configuration +required. However there are a number of configuration options +that can be set such as some details for the System MIB, and +disabling SNMPv3 support (see below). + + +Starting the SNMP agent is not integrated into network +tests other than snmpping below, nor is it +started automatically in normal eCos startup - +it is up to the application to start the agent when it is ready, +at least after the network interfaces are both ‘up’. + + + + +The default build supports all three versions of the SNMP protocol, but without +any dispatcher functionality (rfc 2571, section 3.1.1.2). This has the +following implications : + + 1. There is no community authentication for v1 and v2c. +2. Security provided by v3 can be bypassed by using v1/v2c protocol. + +To provide the dispatcher with rfc 2571 type functionality, it is required to +set up security models and access profiles. This can be provided in the normal +Unix style by writing the required configurations in snmpd.conf +file. Application code may setup profiles in snmpd.conf and +optionally set the environment variable SNMPCONFPATH to +point to the file if it is not in the usual location. The whole concept works +in the usual way as with the standard UCD-SNMP distribution. + + + + + +The support of the trapsink command in the +snmpd.conf file is not tested +and there may be problems for it working as expected. Moreover, in systems that do not +have filesystem support, there is no way to configure a trap-session in the +conventional way. + + +For reasons mentioned above, applications need to initialize their own trap +sessions and pass it the details of trap-sink. The following is a small sample +for initializing a v1 trap session : + + +typedef struct trap { + unsigned char ip [4]; + unsigned int port; + unsigned char community [256]; +} + +trap trapsink; +unsinged char sink [16]; + +... +... + +if (trapsink.ip != 0) { + sprintf (sink, "%d.%d.%d.%d", + trapsink[0], trapsink[1], trapsink[2], trapsink[3]); + if (create_trap_session (sink, + trapsink.port, + (char *)trapsink.community, + SNMP_VERSION_1, + SNMP_MSG_TRAP) == 0) { + log_error ("Creation of trap session failed \n"); + } +} + + + + + +Using snmpd.conf requires the inclusion of one of the file-system packages +(eg. CYGPKG_RAMFS) and CYGPKG_FILEIO. With these two packages included, the +SNMP sub-system will read the snmpd.conf file from the location specified in +SNMPCONFPATH, or the standard builtin locations, and use +these profiles. Only the profiles specified in the ACCESS-CONTROL +section of snmpd.conf file have +been tested and shown to work. Other profiles which have been implemented in +UCD-SNMP-4.1.2's snmpd.conf may not work +because the sole purpose of adding support for the snmpd.conf file has been to +set up ACCESS-CONTROL models. + + +At startup, the SNMP module tries to look for file snmp.conf. +If this file is not available, the module successively looks for files +snmpd.conf, snmp.local.conf and +snmpd.local.conf at the locations pointed to by +SNMPCONFPATH environment variable. In case SNMPCONFPATH + is not defined, the search sequence is carried out in default directories. +The default directories are :/usr/share/snmp, +/usr/local/share/snmp and $(HOME)/.snmp. +The configurations read from these files are used to control both, SNMP +applications and the SNMP agent; in the usual UNIX fashion. + + +The inclusion of snmpd.conf support is enabled by default when suitable +filesystems and FILEIO packages are active. + + + + + + +Currently only one test program is provided which uses SNMP. + + +"snmpping" in the SNMP agent package runs the ping test from +the TCPIP package, with the snmpd running also. This allows you +to interrogate it using host tools of your choice. It supports MIBs +as documented above, so eg. snmpwalk +<hostname> public dot3 under +Linux/UNIX should have the desired effect. + + +For serious testing, you should increase the length of time +the test runs by setting CYGNUM_SNMPAGENT_TESTS_ITERATIONS +to something big (e.g., 999999). Build the test +(make -C net/snmp/agent/current tests) +and run it on the target. + + +Then start several jobs, some for pinging the board (to make +the stats change) and some for interrogating the snmpd. Set $IP +to whatever IP address the board has: + + +# in a root shell, for flood ping +while(1) +date +ping -f -c 3001 $IP +sleep 5 +ping -c 32 -s 2345 $IP +end + +# have more than one of these going at once +setenv MIBS all +while (1) +snmpwalk -OS $IP public +date +end + +Leave to run for a couple of days or so to test stability. + + +The test program can also test snmpd.conf support. It tries to build a minimal +snmpd.conf file on a RAM filesystem and passes it to the snmp sub-system. With +this profile on target, the following snmp[cmd] (cmd=walk, get, set) should +work : + + +snmp[cmd] -v1 $IP crux $OID +snmp[cmd] -v2 $IP crux $OID +snmp[cmd] -v3 $IP -u root -L noAuthNoPriv $OID +snmp[cmd] -v3 $IP -u root -L authNoPriv -A MD5 -a md5passwd $OID + + +The following commands would however fail since they violate the access model : + + +snmp[cmd] $IP public $OID +snmp[cmd] -v1 $IP public $OID +snmp[cmd] -v2c $IP public $OID +snmp[cmd] -v3 $IP -u no_user -L noAuthNoPriv $OID +snmp[cmd] -v3 $IP -u root -L authNoPriv -A MD5 -a badpasswd $OID + + + + + +SNMP clients may use these packages, but this usage is currently +untested: the reason why this port to eCos exists is to acquire +the SNMP agent. The fact that that the SNMP API (for clients) exists +is a side-effect. See the standard man page SNMP_API(3) +for details. There are further caveats below about client-side +use of the SNMP library. + + +All of the SNMP header files are installed beneath .../include/ucd-snmp +in the install tree. The SNMP code itself assumes that directory +is on its include path, so we recommend that client code does the +same. Further, like the TCP/IP stack, compiling SNMP code +requires definition of _KERNEL and __ECOS, +and additionally IN_UCD_SNMP_SOURCE. + + +Therefore, add all of these to your compile lines if you wish +to include SNMP header files: + +-D_KERNEL +-D__ECOS +-DIN_UCD_SNMP_SOURCE=1 +-I$(PREFIX)/include/ucd-snmp + + + + +Currently, the filesystem and persistent storage areas are +left undone, to be implemented by the application. + + +The SNMP library package is intended to support client and +agent code alike. It therefore contains lots of assumptions about +the presence of persistent storage ie. a filesystem. Currently, +by default, eCos has no such thing, so those areas have been simply +commented out and made to return empty lists or say “no +data here.” + + +Specifically the following files have omitted/unimplemented code : + + +PACKAGES/net/snmp/lib/VERSION/src/parse.c + + +contains code to enumerate MIB files discovered in the system +MIB directories (“/usr/share/snmp/mibs”), +and read them all in, building data structures that are used by +client programs to interrogate an agent. This is not required in +an agent, so the routine which enumerates the directories returns +an empty list. + + +PACKAGES/net/snmp/lib/VERSION/src/read_config.c +contains two systems: + + +The first tries to read the configuration file as described in the +snmpd.conf file section and +the second system contains code to record persistent data as files in a +directory (typically /var/ucd-snmp) thus preserving the +state permanently. + + +The first part is partially implemented to support multiple profiles and enables +dispatcher functionality as discussed in . +The second part is not supported at all in the default implementation. As required, +a cleaner interface to permit application code to manage persistent data will be +developed in consultation with customers. + + + + +In the directory + /snmp/agent/VERSION/utils/mib2c, +there are the following files: + +README-eCos notes about running with a nonstandard + perl path. +README.mib2c the README from UCD; full instructions on + using mib2c +mib2c the perl program +mib2c.conf a configuration file altered to include the + eCos/UCD +mib2c.conf-ORIG copyright and better #include paths; and + the ORIGinal. +mib2c.storage.conf other config files, not modified. +mib2c.vartypes.conf + + +mib2c is provided BUT it requires the SNMP perl package SNMP-3.1.0, +and that in turn requires perl nsPerl5.005_03 (part of +Red Hat Linux from 6.0, April 1999). +These are available from the CPAN (“the Comprehensive +Perl Archive Network”) as usual; +http://www.cpan.org/ +and links from there.
