The system-wide configuration files, key files, and the license file are located in the /etc/ssh2 directory. The server daemon uses this location by default. An alternate location can be specified with the -f flag on the command line.
System binaries such as sshd2 and ssh-certd are stored in /usr/local/sbin and library binaries are stored in /usr/local/libexec. User binaries such as ssh2 and sftp2 are stored in /usr/local/bin.
The installation script creates symbolic links, so that sshd points to sshd2 and ssh points to ssh2. If you also have Secure Shell 1.x installed, the SSH Tectia Server installation process modifies the existing link. The old versions can be run with the commands sshd1 and ssh1.
