You can save individual calls with voipmonitor too, and it save the
info in a mysql db, allowing you to search the pcap files easily.

I use pcapsipdump.  It has the added advantage of splitting the captures 
into individual calls

A little more specificity...

I'd like the capture to be in a series of files that can be 'rotated' or
'aged out' so that I can always have x days of traffic on hand but not
have to prune the files to keep the storage requirements reasonable.

On most of my systems I have a script sip-capture:

---
#!/bin/sh

DATE=`date '+%Y%m%d-%H%M%S'`
FILE=sip-`hostname -s`-$DATE.pkt

cd /var/tmp

tcpdump -C 8 -i any -n -p -s 0 -w $FILE udp port 5060 /dev/null 2>&1 
&
---

I start it in /etc/rc.d/rc.local for want of anywhere better.

Being in /var/tmp, cron.daily/tmpwatch deletes files older than 30 days.
I could just have easily put them somewhere else and used the -W option
to tcpdump to remove old files on a rolling basis.

Cheers
Tony

On most of my systems I have a script sip-capture:

---
#!/bin/sh

DATE=`date '+%Y%m%d-%H%M%S'`
FILE=sip-`hostname -s`-$DATE.pkt

cd /var/tmp

tcpdump -C 8 -i any -n -p -s 0 -w $FILE udp port 5060 /dev/null

I start it in /etc/rc.d/rc.local for want of anywhere better.

Heya Steve

I use the same Jeff recommended.

Eg this command would capture SIP traffic in capture files up to

tcpdump -i eth0 -w rollingSIPtrace. -C 100 -W 10 port 5060

Eventually you'd end up with files called 'rollingSIPtrace.00' through 
to 'rollingSIPtrace.09', and when rollingSIPtrace.09 reaches 100MB, 
overwriting of rollingSIPtrace.00 (then rollingSIPtrace.01 etc) would 
commence.


Does that achieve your goal?

Or was the problem that if your server restarts and the command 
auto-executes at boot time then the first file overwritten will be 
rollingSIPtrace.00, not necessarily whichever file was the last 
modified?


I'd like it to only overwrite the oldest, but server restarts are rare 
enough that I think this will be acceptable.

Neither dumpcap or tcpdump know what to do with a HUP (I suspect I could 
configure logrotate to kill dumpcap and then start another instance) but 
I'm still in a position to have to enable/disable the logrotate script as 
I change which hosts need monitoring.

I'd like the capture to be in a series of files that can be 'rotated' or

What bugs you about the output format? There are multiple ways to
display stored information, wireshark can be extremely usefull (and
unstable) or just dump plain text by replaying the pcap with ngrep.

Ways I used so far:

-tshark to produce pcap file (-b duration:x to split up files into time
 intervals
-"sip set log on" to store it plain text in asterisk log files (or pjsip
 set logger on)
-ngrep -W byline to store it in 

Will look into in the near future:
-Homer via res_hep_pjsip
-voipmonitor (didn't know about till just now thanks to Marks reply)
