Roundcube – IMAP Server dropping the connection

When trying to log into your email account via the Roundcube webmail client and IMAP keeps dropping the connection you can fix this by:

  • #tail -20 /var/cpanel/roundcube/log/errors  —>To check the logs
  • #/etc/init.d/courier-imap restart                       —>To restart the IMAP service
  • #/scripts/courierup –force                                  —>To update the IMAP server

If the issue is still not resolved then you may need to change the permissions of the mail directory with the command below but make sure the username is the username from cPanel:

  • #chown -R username:mail /home/username/mail
  • #chown -R username:mail /home/username/etc

 

Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

When trying to log into a server with WHM/cPanel via SSH and you get this error:

Permission denied (publickey,gssapi-keyex,gssapi-with-mic)

This will be because password authentication is disabled in the sshd_config file

To resolve this you can log into WHM and enable the password authentication.

  • WHM >> Security Center >> SSH Password Authorisation Tweak

Then restart the SSH service.

WARNING: RESTRICT_SYSLOG is disabled. See SECURITY WARNING in Firewall Configuration in WHM

When looking at “ConfigServer Security & Firewall” in WHM it gives this error at the top in a yellow box WARNING: RESTRICT_SYSLOG is disabled. See SECURITY WARNING in Firewall Configuration

I resolved this by:

  • Setting RESTRICT_SYSLOG to 3 in the drop down box

This is a description of each number in the drop down box:

# 0 = Allow those options listed above to be used and configured
# 1 = Disable all the options listed above and prevent them from being used
# 2 = Disable only alerts about this feature and do nothing else
# 3 = Restrict syslog/rsyslog access to RESTRICT_SYSLOG_GROUP
