Re: UDP port 752 does what?

Matt,

Yet another sysadmin tool for me to learn!
So I tried "rpcinfo" on a few machines, and was
amazed to find that NFS is always the same
(port 2049), but mountd is all over the place.

On a SunOS 4.1.3 machine:

   program vers proto   port
    100003    2   udp   2049  nfs
    100005    1   udp    708  mountd
    100005    2   udp    708  mountd
    100005    1   tcp    711  mountd
    100005    2   tcp    711  mountd

On a RedHat 5.2 machine:

   program vers proto   port
    100005    1   udp    635  mountd
    100005    2   udp    635  mountd
    100005    1   tcp    635  mountd
    100005    2   tcp    635  mountd
    100003    2   udp   2049  nfs
    100003    2   tcp   2049  nfs

On a SuSE 6.2 machine:

   program vers proto   port
    100005    1   udp    752  mountd
    100005    2   udp    752  mountd
    100005    1   tcp    755  mountd
    100005    2   tcp    755  mountd
    100003    2   udp   2049  nfs
    100003    2   tcp   2049  nfs

Do you happen to know if these ports are
dynamically allocated?
If so, then it's pretty difficult to
firewall/filter them out.

Alan Kennington.
