ports used by informix

[aaronkeith]

hi everyone! i would like to ask for your help. we are currently doing an OS hardening of our unix box (AIX 4.3.3). I've been trying to disable some ports on the OS side but everytime i do that I encounter a problem on informix. Example, i tried closing portmapper, rpc.statd, etc. then i try to login as informix and tried dbaccess, the system hangs.

Do anybody knows what are the ports being used by informix aside from the one assigned to our programs.

your help would be highly appreciated. thank you in advance.

Sincerely,
aaronkeith
