Hi all,

We're trying to setup osmo-gsm-tester on bare metal and are currently experiencing issues with the Jenkins job 'osmo-gsm-tester-runner'. All of our test machines are running Ubuntu Server 20.04 and have been setup following the latest available manual from https://downloads.osmocom.org/docs/latest/osmo-gsm-tester-manual.pdf.

We've trying to use the '4g_srsLTE' example from https://github.com/osmocom/osmo-gsm-tester/tree/master/doc/examples/4g_srsLT... but when trying to run the 'ping' test the following error is returned in the Jenkins console output:

" 14:07:52.867022 run mk-remote-dir(pid=2480): ERR: Terminated: ERROR {rc=1} [trial-21↪4g:srsenb-rftype@soapy↪ping.py:9↪ping.py↪srsepc_10.100.100.113↪host-jenkins@10.100.100.113↪mk-remote-dir(pid=2480)] 14:07:53.015620 run mk-remote-dir(pid=2480): stdout: | (launched: 2022-09-23_14:07:51.598612) | mkdir: cannot create directory ‘/osmo-gsm-tester-srsepc’: Permission denied "

It appears that osmo-gsm-tester is trying to create the directory 'osmo-gsm-tester-srsepc' under root, which is not permitted as the Jenkins user the script runs has does not have permissions. Additionally, it looks like this path is hard-coded in the Python module https://github.com/osmocom/osmo-gsm-tester/blob/master/src/osmo_gsm_tester/o... and also the same applies for srsENB https://github.com/osmocom/osmo-gsm-tester/blob/master/src/osmo_gsm_tester/o...

Is this the intended behaviour? Or have we missed out steps during our bare-metal setup process? I've double-checked that the main unit can SSH into the slave unit without a password so that's not the issue causing "permission denied".

Best regards, Callum.
