Thanks. It turns out that not all program use $http_proxy in bashrc. For pip, which I had problem I had to use "pip --proxy http://somewhere install pkg". So, there is not problem with srun. Hope that it helps other too. Regards, Mahmood On Mon, Aug 3, 2020 at 7:28 PM Matthew BETTINGER < matt

Hello, Not sure what your setup is but check compute nodes route table. Also might need to turn on ipv4 forwarding on whatever is their default gw. Then also firewalls can come in to play too. This isn't a slurm issue , pretty sure! Matt On 8/2/20, 7:53 AM, "slurm-users on behalf of Mahmo

Probably unrelated to slurm entirely, and most likely has to do with lower-level network diagnostics. I can guarantee that it’s possible to access Internet resources from a compute node. Notes and things to check: 1. Both ping and http/https are IP protocols, but are very different (ping isn’t
