Lost connection with Linux agent 2

[zheka]

Hi folks!

Interestingly enough but I discovered a strange behaviour of ArcServe server connecting to an Agent installed on Fedora Core 6 and CentOS 5. After adding a Machine/object to the list of Unix/Linux Systems I enter users credentials to connect to the Agent and got this error message:

Lost connection with HOST_NAME (x.x.x.x)
Do you want to reconnect?

Retrying doesn't work. Could it be a new security feature with 2.6.18 kernel used by FC6 and CentOS5 ? It doesn't happen with CentOS4.4.
My server version is r11.5 SP2, the Agent is r11.5 SP1

Sincerely and hopefully
Eugene

rem out the line “ LD_ASSUME_KERNEL “ in the /opt/CA/BABcmagt/agent.cfg file

Officially not supported but does work on several newer OS version of Linux

 

[zheka]

No, man.

It doesn't work. I thought it would save my ass. Same message: Lost connection. I think I will try to recompile the kernel and make it 2.6.16 not 2.6.18 like it is shipped with CentOS5

1 make sure he recycled “caagent disable all” caagent enable all”
2 test without firewall…
3 ports need to be open 6050 tcp/udp and 41523/41524 udp

 

[zheka]

Still no.
The caagent was restarted both ways, "service bab_agent restart" and the way you mentioned. Firewall is disabled by flushing all iptables.
These are ports that are open:

tcp 0 0 0.0.0.0:6051 0.0.0.0:* LISTEN
udp 0 0 0.0.0.0:41524 0.0.0.0:*

Hey Davidmichel, you know, it works, I just reinstalled the agent and was able to connect to it.

Now more to follow
Same problem with FreeBSD. But what matters there's nothing about the kernel in the agent.cfg file. And most important, after every connection attempts from the BAB server I have cabr.core at the FreeBSD box.
