[Fab-user] fab file run/ openshell commands fail at modified shell

[KESHAV SHRIVASTAVA]

Hi Fab gurus,

Hope you all are doing well!

Fabfile has served me well on multiple linux hosts, but I am stuck here
with a specific host from Sonus which probably has modified shell and thus
there's a small delay after logging into the shell and I see that there's
no response for my commands.

I have tried using both run and open_shell variants and command options
like --no-pty and --linewise but I am not sure what's the root cause and
fix for solving the fabfile problem with modified shell. Any guidance here
will be very much helpful.

See below output from interaction:

[***@home ~]$ fab -f ~/script/Sonus.py lab test

Done.
Disconnecting from sonus.lab.com... done.
