mod_snmp
The mod_snmp module implements SNMPv1 and SNMPv2, for monitoring
of proftpd statistics via SNMP.
The mod_snmp module does not currently support:
Set requests
The mod_snmp module is contained in the mod_snmp/
directory, is intended for ProFTPD 1.3.4rc3 and later, and is not compiled by
default. Installation instructions are discussed
here.
The most current version of mod_sftp is distributed with the
ProFTPD source code.
Please contact TJ Saunders <tj at castaglia.org> with any questions, concerns, or suggestions regarding this module.
2013-01-09: Thanks to <cliles at capario.com> for testing
out most of the mod_snmp features, requesting additional useful
functionality, and providing OpenNMS support/examples.
The SNMPAgent directive configures the mod_snmp
module to act as a "master" SNMP agent/entity, or as an AgentX sub-agent.
(Note that the AgentX capability is not currently implemented.)
The address parameter can be an IP address or a DNS name; this
parameter configures the address/port on which mod_snmp will listen
for UDP SNMP packets. By default, a port of 161 is assumed, use
address:port to specify an alternate port, e.g.:
SNMPAgent master localhost:1161Note that IPv6 addresses should be enclosed in square brackets, as they can contain colons as well, e.g.:
SNMPAgent master [::1]:1161
Multiple addresses can be supplied, allowing mod_snmp to listen
on multiple addresses/ports simultaneously:
SNMPAgent master 1.2.3.4:1161 [a::f]:2262
Note that the SNMPAgent directive is required.
The SNMPCommunity directive configures the community
string (effectively a passphrase) used for authenticating SNMPv1 and SNMPv2
messages.
Note that the SNMPCommunity directive is required.
The SNMPEngine directive controls whether the mod_snmp
will run as an SNMP agent, and handle SNMP messages.
The SNMPLog directive is used to specify a log file for
mod_snmp's reporting. The file parameter given must be
the full path to the file to use for logging.
Note that this path must not be to a world-writable directory and,
unless AllowLogSymlinks is explicitly set to on
(generally a bad idea), the path must not be a symbolic link.
<VirtualHost>, <Global>
The SNMPNotify directive is used to specify the address
of any SNMP manager that should receive any notification (i.e.
SNMPv2 trap) that mod_snmp can generated. Read here for more details on the types of notifications that
mod_snmp supports.
The address parameter can be an IP address or DNS name. By default, a port number of 162 is assumed. To specify the port number, use:
SNMPNotify address:port
Multiple SNMPNotify directives can be configured;
mod_snmp will send notifications to all of them.
The SNMPOptions directive is used to configure various optional
behaviors of mod_snmp.
Example:
SNMPOptions RestartClearsCounters
The currently implemented options are:
RestartClearsCounters
This option will cause mod_snmp to clear/reset every
counter (except for the daemon.restartCount counter)
whenever proftpd is restarted via the SIGHUP signal.
The SNMPTables directive is used to specify a directory that
mod_snmp will use for storing its database files; these files
are used for tracking the various statistics reported via SNMP.
mod_snmp module is distributed with ProFTPD. For including
mod_snmp as a statically linked module, use:
$ ./configure --with-modules=mod_snmp ...Alternatively,
mod_snmp can be built as a DSO module:
$ ./configure --enable-dso --with-shared=mod_snmp ...Then follow the usual steps:
$ make $ make install
Important Security Considerations
Do not configure mod_snmp to listen on a public Internet
address. The information provided via mod_snmp can be used
by attackers to gain more information about your running proftpd,
including being able to determine whether their logins fail due to a wrong
password (in which case, they know that that user name is valid) or not. It
is highly recommended that you configure mod_snmp to only
listen on internal/LAN addresses. Furthermore, you should employ a firewall
rule that rejects any UDP packets from the public Internet to your
proftpd instance.
SNMP Listening Process
When proftpd starts up with mod_snmp enabled, the
mod_snmp module will fork a new process that acts as the SNMP
agent, receiving and responding to all SNMP requests. This SNMP listening
process automatically switches to the privileges configured by the
User and Group directives, and will also automatically
chroot itself to a subdirectory of the SNMPTables directory,
after which all root privileges are permanently dropped.
Example Configuration
The mod_snmp module uses a UDP socket for listening for SNMP
requests. Thus it does not require any separate
<VirtualHost> sections, and does not interfere with the
normal FTP operations.
Here is an example configuration for mod_snmp:
<IfModule mod_snmp.c>
SNMPEngine on
SNMPLog /etc/proftpd/snmp/snmp.log
# Configure the agent to listen on 1.2.3.4, port 161
SNMPAgent master 1.2.3.4 161
# Configure the SNMP community string
SNMPCommunity MySnmpCommunity
# Configure the directory that mod_snmp will use for its database files
SNMPTables /var/proftpd/snmp
</IfModule>
Access Controls for SNMP Messages
Since the SNMPv1/SNMPv2 does not have authentication of "users" as such,
the normal user/group-based ACLs that can be configured in proftpd
have no effect on SNMP messages.
In order to provide IP-based access control, then, the mod_snmp
module supports a <Limit SNMP> section, like the following:
Example:
<Limit SNMP>
# Allow SNMP packets from 10.x.x.x and 127.0.0.1 addresses
Allow from 10., 127.0.0.1
DenyAll
</Limit>
It is easy to spoof the source address for UDP packets, however. So it is
far better (and more secure) to use a firewall to restrict which UDP packets
can reach the mod_snmp address/port.
Logging
The mod_snmp module supports different forms of logging. The
main module logging is done via the SNMPLog directive. For
debugging purposes, the module also uses trace logging, via the module-specific log channels:
proftpd.conf:
TraceLog /path/to/snmp-trace.log Trace snmp:20This trace logging can generate large files; it is intended for debugging use only, and should be removed from any production configuration.

SNMP MIB
The MIB provided for proftpd is distributed with the
mod_snmp module source code, and will be installed by default.
It is contained in the "PROFTPD-MIB.txt" file, and uses SMIv2.
Suggested Future Features
The following lists the features I hope to add to mod_snmp,
according to need, demand, inclination, and time:
Notifications
The mod_snmp module supports sending notifications (via SNMP
traps) whenever certain events occur or conditions are met. Note
that only SNMPv2 traps are generated; there is currently no support for
SNMPv1 traps.
Currently supported notifications:
MaxInstances limit exceeded
To enable notifications, simply configure the address of an SNMP manager
that should be notified via the
SNMPNotify directive.
Frequently Asked Questions
Question: How can I query the mod_snmp
Agent process?
Answer: You can test if your proftpd
supports SNMP with the snmpwalk program (snmpwalk is
a part of the
Net-SNMP project).
Note that you have to specify the SNMP port, which in mod_snmp is
configured via the SNMPAgent directive.
For example, you might try:
# snmpwalk -m /path/to/PROFTPD-MIB.txt -v2c -Cc -c communitystring hostname:161 .1.3.6.1.4.1.17852.2.2If it gives output like:
enterprises.proftpd.modules.snmp.daemon.software = proftpd enterprises.proftpd.modules.snmp.daemon.softwareVersion = ProFTPD Version 1.3.4rc4 (built at Sat Oct 22 2011 11:50:38 PDT) enterprises.proftpd.modules.snmp.daemon.admin = root@127.0.0.1or
PROFTPD-MIB::software.0 = String: proftpd PROFTPD-MIB::softwareVersion.0 = STRING: ProFTPD Version 1.3.4rc4 (built at Sat Oct 22 2011 11:50:38 PDT) PROFTPD-MIB::admin.0 = STRING: root@127.0.0.1or
SNMPv2-SMI::enterprises.17852.2.2.1.1.0 = STRING: "proftpd" SNMPv2-SMI::enterprises.17852.2.2.1.2.0 = STRING: "ProFTPD Version 1.3.4rc4 (built at Sat Oct 22 2011 11:50:38 PDT)" SNMPv2-SMI::enterprises.17852.2.2.1.3.0 = STRING: "root@127.0.0.1"then your
proftpd was compiled with the mod_snmp
module and it is working properly; you should be able to make nice statistics
out of it.
Question: Why doesn't the
scp.scpDataTransfers arc have any directory listing
counters/gauges, such as the ftp.dataTransfers and
sftp.sftpDataTransfers arcs do?
Answer: The SCP protocol does not have the ability
to get just a directory listing; the protocol only transfers files.
