Hi *, At present I have got "original"-ssh (not openSSH) Version 1.2.26 running. So, When I am userA and do a "slogin -l userB targethost", Iam able to read the environment-Variable called REMOTEUSER to determine which user (in this case user A) called userB's shell. This is a not well documented feature of the "original"-ssh and available since I guess Version 1.2.23. As we would like migrate to openSSH in early future, I need to know, If openSSH also provides any mechanism to determine the remote-user (=calling user) eg. by reading an environment variable or a file or whatever. I of cause read the respective man-pages, but I couldn't get any hint how to do. Also the environment-variable REMOTEUSER doesn't seem to exist in OpenSSH? Is that right or Is there any substitution available? Did someone had the same issue? or does someone have a good hin? I would be happy to hear from you! Thanks Christoph Lutz
