Q: How do I find out what process is associated with a socket connection (a network address and port number)? ________________ There are several ways to accomplish this (lsof, pfiles, crash): A1. Use lsof which is available on the net from several locations: ftp://vic.cc.purdue.edu/pub/tools/unix/lsof/lsof.tar.Z http://www.sunfreeware.com/programlistsparc7.html#lsof64 http://www.sunfreeware.com/programlistsparc8.html#lsof http://sunsite.doc.ic.ac.uk/sun/Solaris/freeware lsof examples: Ex: netstat -a shows a connection between hodware port 36169 to ravin port 23 lsof shows the PID owner of the telnet connection. example1# netstat -a ... hodware.36169 ravin.telnet 8760 0 8760 0 ESTABLISHED # lsof -i TCP@hodware:36169 COMMAND PID USER FD TYPE DEVICE SIZE/OFF INODE NAME telnet 2686 steve 6u inet 0x709f21e8 0t0 TCP hodware:36169->ravin:telnet (ESTABLISHED) Ex: netstat -an shows a connection in close_wait. lsof showd the PID and process associated with that port. example2# netstat -an |grep CLOSE_WAIT 10.10.192.103.58046 10.10.37.122.44788 24820 0 24820 0 CLOSE_WAIT # /usr/local/bin/lsof -i | grep 44788 netscape 27096 steve 34u inet 0x300039bf760 0t0 TCP hodware:58046->nop:44788 (CLOSE_WAIT) # ps -elf |grep 27096 8 S steve 27096 19185 0 51 20 ? 9307 ? Feb 18 pts/19 50:03 /opt/netscape/netscape example3# netstat -an |grep 7100 *.7100 *.* 0 0 0 0 LISTEN # /usr/local/bin/lsof -i TCP:7100 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME inetd 4512 root 33u inet 0x300014ef750 0t0 TCP *:fs (LISTEN) to list all ports with a process: example4# lsof -i -P | grep snmpdx snmpdx 5771 root 4u inet 0x60f5add0 0t0 UDP *:161 (Idle) snmpdx 5771 root 5u inet 0x60ded648 0t0 UDP *:38725 (Idle) snmpdx 5771 root 6u inet 0x61101358 0t0 UDP *:38726 (Idle) # to list all TCP connections example5# /usr/local/bin/lsof -i TCP note: lsof is not supported by Sun Enterprise Services, so you are on your own as far as obtaining it, compiling it and running it and any problems you may encounter. ________________ A2. or use Solaris 8 pfiles Solaris 8 added new feature to display socketname using pfiles tool. see proc(1) and below example. solaris 8 pfiles methods : example5# cd /proc ; /usr/proc/binpfiles * | egrep "^[0-9]|sockname" | more .... 968: in.ftpd sockname: AF_INET6 ::ffff:10.1.1.77 port: 21 sockname: AF_INET6 ::ffff:10.1.1.77 port: 21 or example6# su # cd /proc # /usr/proc/bin/pfiles * > /tmp/pfiles.out # vi /tmp/pfiles.out /port: PortOfInterest ?^[0-9] ________________ A3. if you are resourceful enough, use adb or crash to trace down each open file descriptor that a process owns, but there is no way to go in the reverse direction so this would be extremely time consuming and tedious. |
