Hello Again thanks again for all the suggestions.
I haven't quite found out what the processes generating those lines in netstat were but I have I think got closer to an answer. I looked in the netstat manpage and it mentionned the file /proc/net/raw. I looked at this file and found the following: sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode 0: 00000000:0001 00000000:0000 07 00000000:00000000 00:00000000 00000000 0 0 0 1: 00000000:0006 00000000:0000 07 00000000:00000000 00:00000000 00000000 0 0 0 Notice 0001 07 (on line 0) and 0006 07 (on line 1) - you may need to be in X to see the output on oneline. Didn't mean much to me so I searched and found an article on the /proc/net/ directory at : http://linux.oreillynet.com/pub/a/linux/2000/11/16/LinuxAdmin.html Interesting but didn't explain all the fields in the above output. I also found another email at: http://www.cs.helsinki.fi/linux/linux-kernel/Year-1998/1998-44/0500.html Which suggested that the 0 in the inode field means that its an internal kernel socket. I am still not quite sure what exactly an internal socket is (not in any great detail anyway) but no doubt I shall bump across the concept as I read and explore more. If anyone has any suggestions for further reading I would be grateful. thanx again to everyone. t.irvine -- Whoever thinks a faultless piece to see, Thinks what ne'er was, nor is, nor ne'er shall be.
