Re: [snmpsim-users] device recording question

[Jason Kojro-B. <jba...@mo...>]

Thank you for the very quick reply, Ilya!  I was able to get the application to successfully start again.

I will also play with snmprec and see if I can get it running without crashing.

Thank you!

Hi Jason,

Right, use --process-user and --process-group options to specify your non-privileged user&group names to run simulator under their IDs.

This is required to switch from root which is needed to bind to a privileged port like 161.
