Debug Mode

When run in debug mode, SSH Tectia Server outputs useful troubleshooting information to stderr. To run the server in the debug mode, do the following steps:

1. Stop the server by issuing a signal to it:

   # kill `cat /var/run/sshd2_22.pid`
   

   or, if the directory /var/run/ does not exist, use:

   # kill -kill `cat /etc/ssh2/sshd2_22.pid`
   

2. Start the server in the debug mode by using the following command:

   # /usr/local/sbin/sshd2 -d<filter>
   

   This should be the first argument on the command line. The syntax of the filter is as follows:

   "module=level,module=level,..."
   

   Module is the wanted software module (ssh2sftp, for example) and level is the wanted debug level (a number from 0 to 10). Debug level 10 shows all available information, level 0 shows nothing. For example, the following command shows level 4 for all and level 10 for the SFTP server:

   # /usr/local/sbin/sshd2 -d"*=4,Ssh2Sftp*=10" 
   

   The debug information can be also directed to a file:

   # /usr/local/sbin/sshd2 -d"*=4,Ssh2Sftp*=10" > debugfile.txt
   

   For more information on the command-line options, see the sshd2 man page.
3. Connect to the server with a Secure Shell client. The client should also be run in the debug mode.
