[slurm-users] Internet connection loss with srun to a node

A frontend machine is connected to the internet and from that machine, I
use srun to get a bash on another node. But it seems that the node is
unable to access the internet. The http_proxy and https_proxy are defined
in ~/.bashrc

mahmood at main-proxy:~$ ping google.com
PING google.com ( 56(84) bytes of data.

mahmood at main-proxy:~$ srun -p gpu_part --gres=gpu:titanv:1  --pty /bin/bash
mahmood  @fry0:~$ ping google.com

I guess that is related to slurm and srun.
Any idea for that?
