|
|
Hi,
Can someone please explain to me what the point of port 111 (portmap) is, and in which situations i need to run it? I am on a RH8 box, no GUI installed, only other port open is 22.
Cheers,
- J -

It's Sun RPC IIRC.
I presume you know what RPC is? Same on Windows...
I always smile when I see 111 open as it's one of the most exploitable services around.

If you are running a server:yes'

The potmapper manages RPC connections,wich are used by protocols such as NFS and NIS.The portmap server must be running on machines which act as servers for protocols which make use of the RPC mechanism. |

Not generally, definately not for the rest of the world to see (bound to net facing interface).

Cheers dude. Do you know if samba needs portmap running or not?
Can i switch it off with the chkconfig --del <service>, and if so, what is the service name?
also, i have a service listening on my loopback address, on port: 32768. done some googling, there was lots of stuff about GUI stuff, but i dont have a gui on my system. How do i close this port? I also turned off xfslock or something.
Cheers,
_J_

Does the daemon on port 111 just hold all the info about open services? If not then what does it do? Explain in a sentence or so, not a long description.

This is from http://octopus.cdut.edu.cn/~yf17/oe/puis/ch19_02.htm

The fundamental building block of all network information systems is a mechanism for performing remote procedure calls. This mechanism, usually called RPC, allows a program running on one computer to more-or-less transparently execute a function that is actually running on another computer. |
That's as short as I could find.
