DSMCAD port question

[medkev]

I am currently have a TSM 5.4.0.0 Redhat Linux client pointing to a TSM 5.4.0.0 server.

I do have the dsmcad running perfectly fine but have always wondered about the port it opens up.

IE. after dsmcad starts
Ill run:
lsof |grep dsmcad
and get:
dsmcad 24048 root 5u IPv4 161784260 TCP *:44444 (LISTEN)

Is there a way to designate a port that the dsmcad will listen to?

By default, the client, and thus the scheduler, always use 1501.

Here are is my dsm.sys file:

TCPPort 1500

my dsm.opt file only has the option:
servername <tsmservername>

As mentioned earlier, why will it be using such a weird port?
lsof |grep dsmcad
returns "dsmcad 24048 root 5u IPv4 161784260 TCP *:44444 (LISTEN)"
netstat -an |grep LISTEN
returns "tcp4 0 0 *.44444 *.* LISTEN"

To be honest, I don't see what you are seeing.

I guess, this is because I am using prompted mode via a dsmsched scheduler running as a service.

I am guessing it is using the other port to monitor incoming request.

lsof |grep dsmcad | grep LISTEN

Three of the four boxes I checked had these ports:
dsmcad 3282 root 3u IPv4 7454 TCP *:1876 (LISTEN)
dsmcad 3282 root 4u IPv4 7459 TCP *:1581 (LISTEN)

The other had the 1581, but instead of 1876 had what seemed to be a more random port.

Hey Scott,

The 1581 port is the (default) port CAD uses when you also have webclient as part of the managedservices option.

The more random port that you had is what i am questioning.
I am pretty sure other people have seen this issue before, because if you do not put up host based firewalls, you can actually telnet in through that port.
