Dchat

I’ve got one comoputer on which I start dchats.rb. When I try to connect
to it with dchatc.rb on another computer, it takes a while and then it
says:

/usr/lib/ruby/1.8/drb/drb.rb:736:in open': druby://fatburen70.fatburen.org:2693 - #<Errno::ETIMEDOUT: Connection timed out - connect(2)> (DRb::DRbConnError) from /usr/lib/ruby/1.8/drb/drb.rb:729:ineach’
from /usr/lib/ruby/1.8/drb/drb.rb:729:in open' from /usr/lib/ruby/1.8/drb/drb.rb:1189:ininitialize’

from /usr/lib/ruby/1.8/drb/drb.rb:1084:in `method_missing’
from dchatc.rb:37

This is pretty boring and I wonder how to solve it. Thanks!
