Hi,
you all are my last hope :-) I have always been using the
old, now outdated linux_lib port. Yesterday, I have decided
to upgrade to the newer linux_base. Everything works fine and
the typical Linux apps (acroread, rvplayer, wordperfect,...)
are running nicely.
But, this is the problem: We are using Linux matlab5 here
and this one refuses to run. Here are my observations:
First, the license manager is being startet. This one creates
three sockets:
andre@bali:~>sockstat | grep lm_mat
andre lm_matla 69341 0 tcp *.1711 *.*
andre lm_matla 69341 3 tcp *.3768 *.*
andre lm_matla 69341 9 udp *.2214 *.*
Now, matlab starts and contacts the license manager to receive
it's license. The following tcpdump shows what is going on
with the old linux_lib port:
^^^^^^^^^^^^^
tcpdump: listening on lo0

07:26:11.504844 bali.domain.org.1711 > bali.domain.org.3772: P 1:148(147) ack 148 win 17520 (DF)
07:26:11.504861 bali.domain.org.3772 > bali.domain.org.1711: . ack 148 win 17373 (DF)
07:26:11.505002 bali.domain.org.3772 > bali.domain.org.1711: F 148:148(0) ack 148 win 17520 (DF)
07:26:11.505020 bali.domain.org.1711 > bali.domain.org.3772: . ack 149 win 17520 (DF)
07:26:11.505090 bali.domain.org.1711 > bali.domain.org.3772: F 148:148(0) ack 149 win 17520 (DF)
07:26:11.505106 bali.domain.org.3772 > bali.domain.org.1711: . ack 149 win 17520 (DF)
and so on...
Here it works great. Now, with the new linux_base port, whe
find the same socket creation by the licensemanager but matlab
later doesn't talk to it. Not one byte can be seen by tcpdump.
As a result it refuses to run becaus it can't communicate with
the license server...
Have you got any ideas what I can try ?!?
Thanks a lot,
-Andre
