Solaris Network Tracing


You are experiencing issues on the network, or a server process is playing up.



You need to trace network connection. In the example I provide examples using Solaris and Linux. AIX is similar to Linux in the is regard – either using tcpdump or iptrace.



# network trace connection from hostname (solaris)

snoop -x0 src hostname

# network trace connections by port (linux)

tcpdump -A -v -v port 80

tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
20:22:33.456278 IP (tos 0x0, ttl 128, id 63194, offset 0, flags [none], proto: TCP (6), length: 571) > bree.http: P 1:532(531) ack 1 win 32850
….GET /man/bash-1?sect=1&=kill HTTP/1.
