Server restarts every 5 seconds

[timschwab]

I’m running 5.1.26 on CentOS 7 (1511), 64-bit.  NX is stopping/restarting every 5 seconds.

For example, from nxserver.log:

We were not able to reproduce this problem on CentOS 7.2.1511. Could you enable logs in server and node configuration file, restart nxserver, reproduce the problem and then send to us whole /usr/NX/var/log directory to forum[at]nomachine[dot]com or attach them here (size is restricted).

Instructions about debug and collecting logs you can find there: https://www.nomachine.com/DT04M00076.

Hello Tim,
we received logs, and seems that problem is related to your network configuration.

Could you share with us your /etc/hosts file ? Could be through mail again as in case of logs.

[timschwab]

I have attached the /etc/hosts file.

[Britgirl]

Can you forward that to forum[at]nomachine[dot]com?

[timschwab]

Any ideas on a fix?

Hi,

we cannot reproduce this issue in our labs and the /etc/hosts file didn’t show anything abnormal.

We are preparing a patched library with debug logs to send to you, if you are willing to test it.

In the meanwhile, are you able to say what the ‘192.168.14.24’ address is? Is it the IP of the server where you are connecting to?

We found it in the following log, that is somehow related to your problem:

Warning: Refusing connection from ‘192.168.14.24’ port 36450.

[timschwab]

That server is using DHCP.  Nothing on that network has .24 now.  I think 192.168.14.24 was the server with the problem…the server from which I provided logs.

I’ll be happy to try the patched lib when you have it ready.

We sent the package a while back and didn’t hear any further news. This topic will be closed. Make sure you update the software to the latest version. Any problems, please open a new topic.
