My JBW is unable to gain network connectivity, Firewall is set to none, all other programs on my linux computer are working and accessing the net fine. I’m using 2.1pre5.

Please help!

Greetings,
If you hover over the message that tells you that there’s a connectivity problem in the upper right, it’ll usually pop up a tooltip that gives some hints as to the problems it’s seeing.

I also recommend upgrading to the latest Sun version of Java, just to be sure. Sometimes connections fail because of out-of-date certificates, and upgrading the Java version picks up the latest certs. I also strongly discourage using non-Sun versions of Java on Linux as their encryption libraries and Swing libraries have been consistently lagging behind in stability and functionality.

I had this issue with Debian squeeze and
java version “1.6.0_0” OpenJDK Runtime Environment (IcedTea6 1.7pre) (6b17~pre3-1)
and Sun-Java-6 jre installed also (don’t know, if this matters though.
Along with much other output stout showed:
java.net.NoRouteToHostException: Network is unreachable
A qick google search brought me to:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bu…
The fix described there worked for me.

Good luck.

Greetings,
I just spent an hour researching, starting from that link. That’s…that’s just stupid and abusive behavior on the Debian maintainers part. “What the heck, let’s blindly make a change we KNOW will break a lot of packages, just ’cause we can, and it makes IPv6 configuration easier for the 1% of people who give a shit about IPv6!”

Ignoring an RFC on the basis that it’s just ‘informational’, when it clearly recommends against the behavior that they’re implementing is asinine and…and…arrrgh!

Well, crap.

Debian goes on my ‘incompatible/requires workaround’ list until that bug is fixed, whether in Debian or in Sun’s Java implementation, since I strongly recommend against OpenJDK normally. :(

Thanks VERY much, @hanseatic! I’m pretty positive that’ll be extremely useful information for other Debian users.
