ssh connection from remote machine in solaris
Hi!

I have two solaris 10 machines(say 10.1.1.1,10.1.1.2). i have installed rsync on 10.1.1.2,

Code:
10.1.1.1:::
Sun Microsystems Inc.   SunOS 5.10      Generic January 2005
-bash-3.00$ ssh 10.1.1.2 "echo $PATH"
Password:
/usr/java/bin:/home/ppoker/thirdparty/ruby/bin:/usr/bin:/usr/ant/bin:.:/usr/local/bin:.:/usr/java/bin:.:/usr/local/apache2/bin:.:/home/ppoker/bin
-bash-3.00$ ssh 10.1.1.2 "which rsync"
Password:
no rsync in /usr/bin
-bash-3.00$

10.1.1.2::::::
-bash-3.00$ which rsync
/usr/local/bin/rsync
-bash-3.00$

when i execute the command from another machine through ssh, why is it unable to find the rsync command?

regards,
Kiran

Hi.

Code:
-bash-3.00$ ssh 10.1.1.2 "echo $PATH"

Would show the PATH on 10.1.1.1.

Use single quotes, or escape the $ in $PATH.

Code:
-bash-3.00$ ssh 10.1.1.2 'echo $PATH'

or
Code:
-bash-3.00$ ssh 10.1.1.2 "echo \$PATH"

to see what the path actually is on 10.1.1.2

Non interactive ssh sessions do not read profiles. You can do one of these:

First, you can change the default path in /etc/default/login, let's say:
Code:
PATH=/usr/bin:/usr/local/bin

but this affects all users.

Another way is to write
Code:
PATH=/usr/bin:/usr/local/bin

into ~/.ssh/environment. But to make this work, you first have to allow user environments in sshd_config:
Code:
PermitUserEnvironment yes

Be advised, that this may have security related side effects depending on your scenario.

@scottn!! you are correct...it is showing in path of 10.1.1.1, i escaped the $ and it is now showing correct path::
Code:
10.1.1.1:::
-bash-3.00$ ssh 10.1.1.2 "echo \$PATH"
Password:
/usr/bin
-bash-3.00$

@hergp
i checked /etc/default/login file, but path variable is commented in that file.
Code:
//code from /etc/default/login file
# PATH sets the initial shell PATH variable
#
#PATH=/usr/bin:

in this case from where it is taking PATH variable for ssh connection?

Regards,
Kiran

If PATH is commented out in /etc/default/login, then the compiled-in default-default-path is used, which is /usr/bin.
