lighttpd 1.4.26 SSL bug
If you noticed an unexpected outage of my blog and all other sites on this web server, I apologize. This morning, I was greeted by a dead lighttpd web server and when restarting it, it decided to give me this error message instead:
2010-03-05 10:23:01: (network.c.529) SSL: error:00000000:lib(0):func(0):reason(0)
Luckily, a little bit of googling showed that this is a bug in lighttpd 1.4.26′s SSL interface that can be fixed with this little workaround until a new version is released:
cd /tmp wget http://download.lighttpd.net/lighttpd/releases-1.4.x/lighttpd-1.4.26.tar.gz tar xzf lighttpd-1.4.26.tar.gz cd lighttpd-1.4.26 cd src rm network.c wget http://redmine.lighttpd.net/projects/lighttpd/repository/revisions/2716/raw/branches/lighttpd-1.4.x/src/network.c cd .. ./configure && make install
As you can see, the server is happily back up and running. Thanks to sekuritatea for the fix.
Interesting, maybe there’s something wrong with the error returns in openssl 1.0.0-rc5…
Anyway, I found that I still get similar messages in the syslog even after reverting revision r2710 (just not as often), but things work correctly. So it seems like the message may not necessarily be tied to the hanging SSL connections.
I’ll keep digging and file a bug report if I can gather some more concrete info, I guess. Thanks
