netstat -nptl

will show you the processes listening to all tcp ports on your machine

however

25 = mail sever (exim, postfix, sendmail etc..)
68 = speaks for its self
111 = rpc, lots of odd stuff uses rpc.. mainly nfs.. do you use nfs.. ?
631 = cups

783/898 = probably nfs

however, the output of netstat will help.
