ngrep output question


Im running the following ngrep command and since I need a text output file I was doing the following:

nohup ngrep -O soap_capture.pcap -W byline -d xxxx port 99999 &  >> log_$LOG_DATE.log

But the problem is that its truncates some of the lines messing with the envelopes:

T -> [AP]
T -> [AP]


Is there a way to prevent this from happening? - this output truncation.

Add -the "-l" (lowercase L, not uppercase i !) flag to make the output line buffered.

Do you really need the pcap output file? if you don't you can save CPU cycles and I/O load by omitting "-O soap_capture.pcap"

nohup ngrep -l  -W byline -d xxxx port 99999 &  >> log_$LOG_DATE.log

If you let ""-O soap_capture.pcap" in place you can later try printing that file, perhaps iit will give the desired output:

ngrep -I soap_capture.pcap -W byline

This time it's an uppercase i    :-)
