Configuring the SSH2 Process to Use
As mentioned earlier, the SSH and SFTP clients will interact with a running instance of the SSH2 object file. There are
multiple ways to specify which instance to use:
• The –S runtime option will explicitly choose a specific instance by its process name. The following example
starts an SFTP client picking the SSH2 instance with the process name $SSH1 (please note that under OSS the
process name is embedded into single quotes to allow the special character $ to be used as part of a shell
command):
>: sftposs -S '$ssh1' burgt@10.0.0.201
Connecting to 10.0.0.201...
sftp>
• By setting an environment variable named SSH2PREFIX in the client environment you can activate a heuristic
to pick an SSH2 process depending on the CPU number it is running in. Please refer to "
Load-Balancing
Outbound SSH Sessions" in the chapter "Configuring and Running SSH2" for details.
• By setting an environment variable SSH2_PROCESS_NAME in the OSS shell specifying the SSH2 process the
client should use.
• By adding a define =SSH2^PROCESS^NAME, CLASS MAP and the SSH2 process name set as FILE value.
Inquiring User Name If Not Supplied
The SSH[OSS] and SFTP[OSS] clients accept argument user@host as well as just host. If no user is specified the current
user, i.e. the user who started the client, is taken as default value. This default can be changed via environment variable
INQUIREUSERNAMEIFNOTSUPPLIED, which must be defined in the environment (TACL/shell) the clients are
started from.
If PARAM/environment variable INQUIREUSERNAMEIFNOTSUPPLIED is set to true and the username was not
specified, the SFTP[OSS] and SSH[OSS] clients now prompt the user for the username:
> ssh 10.0.0.196
comForte SSH client version T9999G06_22Jan2014_SSH_0097
User name @10.0.0.196: test
You have no private keys in the key store.
Trying password authentication.
Enter test@10.0.0.196's password:
...
If the user just hits return the default user name applies. If the PARAM/environment variable
INQUIREUSERNAMEIFNOTSUPPLIED is not defined or is set to value FALSE the default user name is assumed as
well (i.e. the behavior is then identical before introduction of INQUIREUSERNAMEIFNOTSUPPLIED).
