Help needed in setting up more than one peer on single user system.

[Vikas Maurya]

Hi,

I have tried using two ways of setting up two peers on my system. first one from tutorial here https://docs.gnunet.org/tutorial/gnunet-tutorial.html/Starting-Two-Peers-by-Hand.html#Starting-Two-Peers-by-Hand and second using gnunet-testbed-profiler with --num-peers=2.

but in both the above methods I am facing problem with generating relevant configuration file to use. In profiler method I do not give any template configuration file (assuming it generates configuration file automatically for each peer, am I wrong?) I get the following errors, and I do not see any peers running when I issue gnunet-core command.

My doubts are

1. how to use this gnunet-testbed-profiler correctly?

2. How to create config file for different peers on same system? (I tried using gnunet-testing for this but config files generated using this doesn't seem to work , which I tried using while following steps in tutorial mentioned above).

3. If I run multiple peers on a system How to check these peers are running correctly.

Thanks,
