How to use sshd_config - PermitUserEnvironment option

Question

I have client1 and client2 both are linux machines. From client1:

client1$ssh root@client2 "env"

it displays list of ssh variables from client2.

Things I did on client2:

I want to add new variable to client2 . So I edited sshd_config to

PermitUserEnvironment yes

and created a file environment under ssh with following entry Hi=Hello

then restart sshd

/etc/init.d/sshd

---

Now from client1 trying the same command

client1$ssh root@client2 "env"

didn't provide the new variable "Hi".

Answer 1

and created a file environment under ssh with following entry Hi=Hello

You should create the file /root/.ssh/environment on client2, assuming that /root is the home directory of root.
