Using DRb on a Linux box

ruby-talk
1

When trying to use DRb on my Linux box (SuSE 7.3 running Ruby 1.6.7), I get
a SocketError indicating that getnameinfo: ai_family not supported.

According to the “Ruby Developer’s Guide”, page 337, the fix for this is to
recompile Ruby with ./configure --enable-ipv6 --with-lookup-order-hack=INET.
I tried that and it didn’t work!!

Looking at the DRbServer class, I noticed that if the uri parameter to the
initialize function is nil that the uri is set accordingly …

 uri = 'drbuy://:0' unless uri

shouldn’t this be …

 uri = 'druby://0.0.0.0:0' unless uri

It seemed to solve the problem on my system. What is the correct solution?
Why did recompiling Ruby not work?

Thanks!!

Would it be a big hassle to try this with ruby compiled without
those options?
without …hack=INET with …hack=INET
druby://:0 No No
druby://0.0.0.0:0 ??? yes

It may help people later.

Thanks!!

Does that mean that the same “getnameinfo” error occured after recompiling ruby?
