Howdy!
I'm running synergy w. os x as server and linux as client. The mac installation has been migrated from an earlier mac. When I try to start synergy server it complains about the host name. The new mac is named 'apollo' and the old one 'agni'. When I start it tries to find screen agni (and can't find one). This, in my view, points to some old config file somewhere that still has the name agni. But I can't find it! the hostname command returns 'apollo' so it's not a matter of not knowing the correct name. As a workaround I've set 'agni' as an alias and that seems to work but it would be nice to know the origins of this problem.
