Re: [ADSM-L] tcp port usage of client

Hi all,

1) Interactive
If you're using the client in an interactive way (dsmc), it simply connects to 
the server TCPPORT (1500).

2) Schedmode Polling
It's the same if using the SCHEDMODE POLLING option. 
No matter if the TSM Scheduler runs by his own or is launched by the CAD?

3) Schedmode Prompted
If using the SCHEDMODE PROMPTED option, behavior depends on the way the TSM 
Scheduler is running.

If TSM Scheduler is running by himself (dsmc sched), then the dsmc sched is 
listenning to the TCPCLIENTPORT (1501 by default, or another backup one 17xx if 
1501 is already binded by another process. ANS1018E if TSM is using this port).

If TSM Scheduler is managed by the CAD, it it listenning to a random port, 
unless you specify it by using the WEBPORTS option.

Plus,
I believe a client in polling mode uses 1500,
a client in prompted mode uses both 1500 and 1501, unless 1501 isn't available 
then it will pick something else.

Is that wrong?

Your analysis looks correct to me.

Ports for the CAD are specified with the webport option.
Only valid if managedservices is used with the schedule option.

Managedservices schedule

I believe the httpport option is only used if you have

Managedservices web 

Or managedservices web schedule


The random ports for dsmcad I believe are when webport is not specified.

Subject: [ADSM-L] tcp port usage of client

Hi Everyone,

I am SO confused . . .

The security folks are checking/verifying what tcp ports are used on some 
servers.  We got the question of just what ports TSM clients are using on these 
servers.  The clients are all behind a firewall, but the question is not about 
firewall port.  Rather it's just what ports these TSM clients are using.

Client backups run just fine thru the firewall.
Clients are all AIX.
The TSM server the clients backup to runs on tcpport 1500 (default).
The dsm.opt is empty.

Here is the dsm.sys file on one of the AIX clients.
 SErvername  tsmX
   COMMmethod          TCPIP
    TCPPort            1500
    TCPServeraddress   tsmX
    nodename           clientY
    passwordaccess     generate
    inclexcl           /usr/tivoli/tsm/client/ba/bin/inclexcl
    schedlogname       /usr/tivoli/tsm/client/ba/bin/dsmsched.log
    webports 2123 2124
    httpport 1581 1582
    schedlogret        5
    errorlogname       /usr/tivoli/tsm/client/ba/bin/dsmerror.log
    errorlogret        5
    txnbytelimit       25600
    tcpwindowsize      64
    schedmode          prompted
    tcpbuf             64
    resourceutilization 3

This seems messed up:
  - has two entries on httpport which is invalid, not sure what result of this 
is.
  - webports is specified, but is not using managedservcies.  I thought
      this options only applied if using managedservices with the
      scheduler running under cad.
  - Since scheduler is running directly (not under cad), there is no
      tcpclientport parm, so this is defaulting to 1501 (I think).
      This is the port the tsm server uses to prompt the client.
  - How does a webports and httport (that is bad) interact?

WIth all that, what tcp ports would a client like this be using?

I come up with this:
  1501 (dsmsched listening for prompt from TSM server)
  1581 (http connection for web gui via dsmcad)
  2123/2124 ? - no, parm is ignored
  1582 ? - no, invalid 2nd port on httpport
  random ? - I read several things about the client using a random port

Now, the security folks found dsmcad running on a wide range of ports on 
different servers:  9385, 37872, 29423, some others.

Any thoughts are appreciated, especially how to set specific ports for the tsm 
client to use.


Thanks

Rick
