SSH access is slow

v6

(Federico Ballarini) #1

NethServer Version: 6.9
Module: SSH

Hello, I have a firewall with Nethserver 7 and the SSH access is very fast.
Under the firewall I have a server with Nethserver 6.9 and RAID software enabled that I use for virtualization but the SSH access is very slow.
What can I do?

Thanks.

verify the ram and the load of your server

top or htop is your friend or one shot command

uptime;free -h

The access is slow also with the ram used at 40%…

and the load ???

File is templated, you need a custom fragment
Search here and in the documentation

The developer manual has some info on how the template system works.
I think Stefano is referring to the UseDNS no sshd option.
