Opening ports

[nitinkgoud]

Hi Guys,
I want to check which ports are open.
And how do i open closed ports?
I am running solaris 8.

You should download lsof if you don't already have it.

ftp://ftp.sunfreeware.com/pub/freeware/sparc/8/lsof-4.74-sol8-sparc-local.gz

After it's installed just run:

lsof|grep -i listen

If you see something you want to stop you can run

lsof|awk '/LISTEN/{print $2}'|xargs kill -9

That will only stop it from running at that time, not on a reboot (start time)

perl -e 'print $i=pack(c5,(40*2),sqrt(7600),(unpack(c,Q)-3+1+3+3-7),oct(104),10,oct(101));'

Or, more simply, netstat -a and look for LISTEN.

You usually open closed ports by starting a piece of software that listens on that port. For example, to open port 22 for SSH you would start the sshd process.

Also some ports can be opened by configuring inetd (or xinetd, depending on OS), see the man page for details.
