Title: ssh connection issues
Post by: josephgodwinke on May 28, 2021, 09:27:22 PM

I try to connect to another server and copy files with rsync but I get this error

Code: [Select]

ssh: connect to host 123.45.67.89 port 2211: Connection refused
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: unexplained error (code 255) at io.c(226) [Receiver=3.1.2]

ssh port is correct

Are you able to connect via SSH with the data? Probably your server has blocked TCP OUT to port 2211
Try to open the port in /etc/csf/csf.conf => TCP_OUT or try to disabvle firewall and test.

Temporary workaround was tunneling ports and agent forwarding. Connected to the remote server for rsync and scp then after I was done I reverted the backup /etc/ssh/sshd_config

Firewall accepts TCP inbound/outbound connections from port 2211.
