hi...
hello.
to "watch" what a process is "doing" you can use the command "truss" on sun solaris. e.g. when you want to "trace" the command ls, do:
truss ls
you will see the open syscalls and what the command is doing. to see "open networkhandles" (ports, rpc, etc...) you can use
netstat -a
and
rpcinfo
cheers, alex...
