=net-misc/balance-3.40 has an issue with IPv6 that i cannot seem to work around. When running 3.40, this message is returned: setsockopt(IPV6_V6ONLY=0): Protocol not available Oddly, IPv6 is implemented in the kernel I am using (2.6.31-gentoo-r6). Here's a full debug output from the program: # balance -d -f -b 192.168.0.157 30321 192.168.1.35:3389 argv[0]=balance bindhost=192.168.0.157 source port 30321 file /var/run/balance/balance.30321.192.168.0.157 already exists setsockopt(IPV6_V6ONLY=0): Protocol not available It seems other distros have had this issue, and have reported that it is resolved in 3.48. Here is an example: https://bugs.launchpad.net/ubuntu/+source/balance/+bug/476437 As it seems that this issue is limited to 3.40 as that is when IPv6 was added I think, 3.35 does work for what I need so I'll drop back to that.

In CVS. Thanks for reporting.
(In reply to comment #1) > In CVS. Thanks for reporting. > I rebuilt today and it is unfortunately not working. No longer the same bug, but rather it is silently exiting. Here is one of the commands I am running: # balance -b 192.168.0.157 30321 192.168.1.35:3389 This exists silently (though it is supposed to fork, so that's not surprising). If I turn on debugging, I get this: # balance -d -b 192.168.0.157 30321 192.168.1.35:3389 argv[0]=balance bindhost=192.168.0.157 source port 30321 file /var/run/balance/balance.30321.192.168.0.157 already exists The last line is just a warning. If I call balance and tell it not to daemonize, I get this: # balance -f -d -b 192.168.0.157 30321 192.168.1.35:3389 argv[0]=balance bindhost=192.168.0.157 source port 30321 file /var/run/balance/balance.30321.192.168.0.157 created shmget: Invalid argument I'm not sure what is going on here.

Seems there may be a work around by using the -M option: M Use memory mapping for IPC instead of shared memory Using -M allows balance to work as expected. I guess there is an issue with shared memory in general, or maybe I'm doing something wrong with shared memory on my server? All I know about shm is what fstab has: shm /dev/shm tmpfs nodev,nosuid,noexec 0 0
Hi, I'm the new maintainer for this package, please update to version 3.54 and report if the problem persists. Thank you, Michael
I built 3.54 on the host (.0.157) and and started by testing the following: balance -b 192.168.0.157 -f -d 3080 192.168.1.35:80 For the life of me, I couldn't get it to work. I tried to use -B and -M to no avail. It would always give me a timeout error. I tried different services as well, such as SSH instead of HTTP, but there was no change. On a different workstation, I ssh'd into the host (0.157, like above) and did the exact same command, parameters and all. This time it worked, with no timeout issues at all. I basically had two shells on the same server, one working with balance and the other not working. I chalked it up to something weird in the environment on the non-working shell (this is also the shell that built balance in the first place) and killed all my server sessions on that workstation. Upon re-logging into the host everything started working. In the working shell, I tested with and without the -B, -b and -M parameters. Everything looks solid.
Additional note: in the syslog, every time I load balance, I see this log line: Balance[17774]: setsockopt(IPV6_V6ONLY=0) failed
