[Wien] parallel ssh error

[Gavin Abo]

After you set both "SendEnv *" and "AcceptEnv *", did you restart the 
sshd service [1]?  The following illustrates steps that might help you 
verify that WIENROOT appears on a remote vlsi node:

username at computername:~$ echo $WIENROOT

username at computername:~$ export WIENROOT=/servernode1
username at computername:~$ echo $WIENROOT
/servernode1
username at computername:~$ ssh vlsi
Welcome to Ubuntu 18.04.3 LTS (GNU/Linux 4.15.0-64-generic x86_64)
...
Last login: Sat Sep 28 12:04:07 2019 from xxx.x.x.x
username at computername:~$ echo $WIENROOT

username at computername:~$ exit
logout
Connection to vlsi closed.
username at computername:~$ sudo gedit /etc/ssh/ssh_config
[sudo] password for username:

username at computername:~$ sudo gedit /etc/ssh/sshd_config

username at computername:~$ grep SendEnv /etc/ssh/ssh_config
     SendEnv LANG LC_* WIENROOT
username at computername:~$ grep AcceptEnv /etc/ssh/sshd_config
AcceptEnv LANG LC_* WIENROOT
username at computername:~$ ssh vlsi
...
username at computername:~$ echo $WIENROOT
/servernode1
username at computername:~$ exit
