Unabled to contact slaves nodes

[camilo-17]

Hi Dear support team

I have a problem with Nxcloud cluster

I have 1 master node and 3 slaves nodes,

The GUI says that last contact was two days ago, I checked and everything looks fine, /nxcloud/conf/cfg.properties has ok master_ip and cluster_mode = 2 and /etc/hosts has an entry for my master node and also running :
telnet 10.0.1.90 19003
telnet 10.0.1.90 19004

it works and get conected to my master node, also I try to restart nxcloud (first master and then slaves) but notining happends.

Best regards

Send me the log files on /nxcloud/log/ of the slave node. 'support @ nxfilter.org'.

When you set DEBUG mode for the slave node, you will see this kind of message in the log file once in a minute.

DEBUG [04-01 09:53:03] - NTpL, /HELLO 0 0 0 0

This is how to set DEBUG mode, https://nxfilter.org/tutorial/i-faq.php#enable-debug

This one has been fixed by restarting slave nodes. Seems like when you reboot your master node server, your slave nodes couldn't detect the socket closing events. That can happen on Linux systems.

When you restart NxCloud, do these steps to be 100% sure,

sudo systemctl stop nxcloud
tail /nxcloud/log/nxfilter.log
sudo systemctl start nxcloud
tail /nxcloud/log/nxfilter.log

Use tail command to see if it stopped well and started well. NxCloud needs to take several seconds to close all the resource connections before it stops. So, it's safe to wait for 5 secs after you stopping it to start it again.
