funniliy when i change my hostname to e.g. "lemen-h1.lan" and add the entry to /etc/hosts i can start "erl -name test" without it erroring. but eclipse & erlide still don't start.

If your host name has a dot in it, it won't work; Java and Erlang disagree regarding the name being a local name or a FQDN.

It may be so that dashes confuses them too. Did you try to name your machine lemen_l1 or just lemen?

Is the output from epmd from the same session when the logs said "couldn't connect to epmd"?

my hostname does not contain a dot.
yes epmd is the same session. that's what's confusing me a bit because log output says he couldn't reach epmd, but epmd log says otherwise.

i tried running again with my hostname changed to "lemen" and with no network connected but still yields the same result.

You mentioned trying "lemen-l1.lan", that's where the dot is.

Epmd didn't accept the connection from the Java node... Strange, because this part is pure jinterface, has nothing to do with erlide's handling of host names.

Please try without dashes and I'll be thinking about other answers.

like asked, i tried with:

  • no local domain
  • hostname without dash (changed to underscore)
  • no network connection so only /etc/hosts schould supply dns results

also tried on a different machine with the same results.

i still hope it's not an error from my side xD

Hmmmm... This kind of issues is so difficult to debug remotely...

Ok, try to uninstall erlide and reinstall the previous version from http://download.erlide.org/update/archive/releases/0.24.2/

The thing is that I didn't do any changes that should affect this... Please let me know if 0.24.2 works (again)

tried that version as well ... different error.

i'm just trying to setup erlide debugging then i'll take a peak inside.

Which version worked for you last?
Did you make any other changes to the system in the meanwhile?

i think its an error from my side.
the socket in com.ericsson.otp.erlang.OtpEpmd tries contacting "localhost" but proxy does not know how to resolve it and then crashes and the node can't be reached.
my SOCKS proxy gives back some malformed info because contacting localhost through proxy is kind of difficult 😅
that's that.
looking further down one may want to consider changing the socket so proper SocketImpl is used(instead of SocksSocketImpl in my case) so no proxy at all maybe used or configure no_proxy somehow.

thanks for your time
