It will +probably not run on any other platform. Also, it does no provide TLS services. +Encryption can be provided by using <a href="rsyslog_stunnel.html">stunnel</a>. +<p>This module has no limit on the number of listeners and sessions that can be used. +<p>Multiple receivers may be configured by +specifying $InputPTCPServerRun multiple times. +</p> +<p><b>Configuration Directives</b>:</p> +<p>This plugin has config directives similar named as imtcp, but they all have <b>P</b>TCP in +their name instead of just TCP. Note that only a subset of the parameters are supported. +<ul> +<li>$InputPTCPServerAddtlFrameDelimiter <Delimiter><br> +<b>CURRENTLY DISABLED</b><br> +This directive permits to specify an additional frame delimiter for plain tcp syslog. +The industry-standard specifies using the LF character as frame delimiter. Some vendors, +notable Juniper in their NetScreen products, use an invalid frame delimiter, in Juniper's +case the NUL character. This directive permits to specify the ASCII value of the delimiter +in question. Please note that this does not guarantee that all wrong implementations can +be cured with this directive. It is not even a sure fix with all versions of NetScreen, +as I suggest the NUL character is the effect of a (common) coding error and thus will +probably go away at some time in the future. But for the time being, the value 0 can +probably be used to make rsyslog handle NetScreen's invalid syslog/tcp framing. +For additional information, see this +<a href="http://kb.monitorware.com/problem-with-netscreen-log-t1652.html">forum thread</a>. +<br><b>If this doesn't work for you, please do not blame the rsyslog team. Instead file +a bug report with Juniper!</b> +<br>Note that a similar, but worse, issue exists with Cisco's IOS implementation. They do +not use any framing at all. This is confirmed from Cisco's side, but there seems to be +very limited interest in fixing this issue. This directive <b>can not</b> fix the Cisco bug. +That would require much more code changes, which I was unable to do so far.
