Installation instructions are discussed <a href="#Installation">here</a>. <p> The most current version of <code>mod_sftp</code> is distributed with the ProFTPD source code. <h2>Author</h2> <p> Please contact TJ Saunders <tj <i>at</i> castaglia.org> with any questions, concerns, or suggestions regarding this module. <h2>Thanks</h2> <p> <i>2013-01-09</i>: Thanks to <cliles <i>at</i> capario.com> for testing out most of the <code>mod_snmp</code> features, requesting additional useful functionality, and providing OpenNMS support/examples. <h2>Directives</h2> <ul> <li><a href="#SNMPAgent">SNMPAgent</a> <li><a href="#SNMPCommunity">SNMPCommunity</a> <li><a href="#SNMPEngine">SNMPEngine</a> <li><a href="#SNMPLog">SNMPLog</a> <li><a href="#SNMPMaxVariables">SNMPMaxVariables</a> <li><a href="#SNMPNotify">SNMPNotify</a> <li><a href="#SNMPOptions">SNMPOptions</a> <li><a href="#SNMPTables">SNMPTables</a> </ul> <p> <hr> <h3><a name="SNMPAgent">SNMPAgent</a></h3> <strong>Syntax:</strong> SNMPAgent master|agentx <em>address[:port] ...</em><br> <strong>Default:</strong> <em>None</em><br> <strong>Context:</strong> server config<br> <strong>Module:</strong> mod_snmp<br> <strong>Compatibility:</strong> 1.3.4rc3 and later <p> The <code>SNMPAgent</code> directive configures the <code>mod_snmp</code> module to act as a "master" SNMP agent/entity, or as an AgentX sub-agent. (<b>Note</b> that the AgentX capability is not currently implemented.) <p> The <em>address</em> parameter can be an IP address or a DNS name; this parameter configures the address/port on which <code>mod_snmp</code> will listen for UDP SNMP packets.

For including <code>mod_snmp</code> as a statically linked module, use: <pre> $ ./configure --with-modules=mod_snmp ... </pre> Alternatively, <code>mod_snmp</code> can be built as a DSO module: <pre> $ ./configure --enable-dso --with-shared=mod_snmp ... </pre> Then follow the usual steps: <pre> $ make $ make install </pre> <p> <hr> <h2><a name="Usage">Usage</a></h2> <p> <b>Important Security Considerations</b><br> Do <b>not</b> configure <code>mod_snmp</code> to listen on a public Internet address. The information provided via <code>mod_snmp</code> can be used by attackers to gain more information about your running <code>proftpd</code>, 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 <b>highly recommended</b> that you configure <code>mod_snmp</code> to only listen on internal/LAN addresses. Furthermore, you should employ a firewall rule that <b>rejects</b> any UDP packets from the public Internet to your <code>proftpd</code> instance. <p> <b>SNMP Listening Process</b><br> When <code>proftpd</code> starts up with <code>mod_snmp</code> enabled, the <code>mod_snmp</code> 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 <code>User</code> and <code>Group</code> directives, and will also automatically <b>chroot</b> itself to a subdirectory of the <code>SNMPTables</code> directory, after which all root privileges are permanently dropped. <p> <b>Example Configuration</b><br> The <code>mod_snmp</code> module uses a UDP socket for listening for SNMP requests. Thus it does not require any separate <code><VirtualHost></code> sections, and does not interfere with the normal FTP operations. <p> Here is an example configuration for <code>mod_snmp</code>: <pre> <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> </pre> <p> <b>Access Controls for SNMP Messages</b><br> Since the SNMPv1/SNMPv2 does not have authentication of "users" as such, the normal user/group-based ACLs that can be configured in <code>proftpd</code> have no effect on SNMP messages. <p> In order to provide IP-based access control, then, the <code>mod_snmp</code> module supports a <code><Limit SNMP></code> section, like the following: <p> Example: <pre> <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> </pre> 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 <code>mod_snmp</code> address/port. <p> <b>Logging</b><br> The <code>mod_snmp</code> module supports different forms of logging. The main module logging is done via the <code>SNMPLog</code> directive. For debugging purposes, the module also uses <a href="../howto/Tracing.html">trace logging</a>, via the module-specific log channels: <ul> <li>snmp <li>snmp.asn1 <li>snmp.db <li>snmp.mib <li>snmp.msg <li>snmp.notify <li>snmp.pdu <li>snmp.smi </ul> Thus for trace logging, to aid in debugging, you would use the following in your <code>proftpd.conf</code>: <pre> TraceLog /path/to/snmp-trace.log Trace snmp:20 </pre> This trace logging can generate large files; it is intended for debugging use only, and should be removed from any production configuration. <p> <b><code>mod_snmp</code> OIDs</b><br> <b>Note</b> that all <code>mod_snmp</code> OIDs begin with 1.3.6.1.4.1.17852.2.2.

MIB</b><br> The MIB provided for <code>proftpd</code> is distributed with the <code>mod_snmp</code> module source code, and will be installed by default. It is contained in the "PROFTPD-MIB.txt" file, and uses SMIv2. <p> <b>Suggested Future Features</b><br> The following lists the features I hope to add to <code>mod_snmp</code>, according to need, demand, inclination, and time: <ul> <li>AgentX support <li>SNMPv3 support <li>Controls support (<i>e.g.</i> for "ftpdctl snmp" action) </ul> <p><a name="Notifications"></a> <b>Notifications</b><br> The <code>mod_snmp</code> module supports sending notifications (via SNMP <i>traps</i>) whenever certain events occur or conditions are met. Note that only SNMPv2 traps are generated; there is currently no support for SNMPv1 traps. <p> Currently supported notifications: <ul> <li><code>MaxInstances</code> limit exceeded <li>Failed FTP login due to bad/wrong password <li>Failed FTP login due to bad/unknown user name </ul> <p> To enable notifications, simply configure the address of an SNMP manager that should be notified via the <a href="#SNMPNotify"><code>SNMPNotify</code></a> directive. <p><a name="FAQ"> <b>Frequently Asked Questions</b></a><br> <font color=red>Question</font>: How can I query the <code>mod_snmp</code> Agent process?<br> <font color=blue>Answer</font>: You can test if your <code>proftpd</code> supports SNMP with the <code>snmpwalk</code> program (<code>snmpwalk</code> is a part of the <a href="http://net-snmp.sourceforge.net"><code>Net-SNMP</code></a> project). Note that you have to specify the SNMP port, which in <code>mod_snmp</code> is configured via the <a href="#SNMPAgent"><code>SNMPAgent</code></a> directive. <p> For example, you might try: <pre> # snmpwalk -m /path/to/PROFTPD-MIB.txt -v2c -Cc -c communitystring hostname:161 .1.3.6.1.4.1.17852.2.2 </pre> If it gives output like: <pre> 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@127.0.0.1 </pre> or <pre> 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@127.0.0.1 </pre> or <pre> 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" </pre> then your <code>proftpd</code> was compiled with the <code>mod_snmp</code> module and it is working properly; you should be able to make nice statistics out of it. <p> <font color=red>Question</font>: Why doesn't the <code>scp.scpDataTransfers</code> arc have any directory listing counters/gauges, such as the <code>ftp.dataTransfers</code> and <code>sftp.sftpDataTransfers</code> arcs do?<br> <font color=blue>Answer</font>: The SCP protocol does not have the ability to get <i>just</i> a directory listing; the protocol only transfers files. <p> <hr> <font size=2><b><i> © Copyright 2011-2017 TJ Saunders<br> All Rights Reserved<br> </i></b></font> <hr> </body> </html>
