Troubleshooting TCP Wrappers

If configuring TCP wrappers causes problems, please check the following:

  1. Make sure that you are not experiencing any network connectivity problems.
  2. Make sure that SSH Tectia Server is running:
    $ kill -0 `cat /var/run/sshd2_22.pid`
    
    or
    $ kill -0 `cat /etc/ssh2/sshd2_22.pid`
    
    If you receive the message "No such process", restart the sshd2 daemon.
  3. Check your /etc/hosts.allow and /etc/hosts.deny files.
    • Ensure that the client's IP address or hostname is correct.
    • If you are using a hostname, you must supply the fully qualified domain name.
  4. If you changed something in the sshd2_config file, you need to HUP (hangup) the sshd2 daemon.
  5. Run tcpdchk and tcpdmatch. These programs are used to analyze and report problems with your TCP wrappers setup. Please see the man pages for more information on these commands.
