All our shared hosting servers use a custom port for SSH, since it minimizes the number of automated brute force attacks against SSH. The port we use for SSH is port 831.
Below you'll find a few examples of how to use the custom port:
# SSH
ssh -p831 -l username nlsh0X.shared-infra.net
# SCP
scp -P831 ~/file.txt username@nlsh0X.shared-infra.net:~/
# RSYNC
rsync -av -e 'ssh -p831' ~/file.txt username@nlsh0X.shared-infra.net:~/
