I notice the open file limit on DD-WRT (build 13832) for WRT610Nv2 is 1024.
$ ulimit -a
open files (-n) 1024
I would like to increase this for the transmission user, since my downloads often get halted with "Too many open files". Transmission has an open files setting, but this limit is enforced by OS (at least that is how it works on an regular linux system).
So, knowing how DD-WRT is trimmed down, is there any way to increase this limit in something equivalent to /etc/security/limits.conf?
And yes, I know there are side-effects to doing this, but currently my router is handling all this just fine, and I'd like to see how far I can push this modest hardware. Previously I've been using Linux box as my home router, but I would like to not run a 8-core Xeon machine for 24/7 just to route the cable internet and run some torrents. Trying to cut $20 a month from the electricity bill (wall power meter says that machine costs me $28 per month to run 24/7). _________________ Linksys WRT610N v2 (DD-WRT) :: D-LINK DIR-825 (OpenWrt) :: The World in 35mm :: Bandwidth Shaping with DD-WRT
well, a workaround is in /opt/etc/init.d/S90transmission startup script. Right before the script does an `sudo` to start the transmission daemon(s), you can use ulimit to increase the max open file limit and then the sudo'd process will inherit these limits.
since I don't want transmission daemons having any priority over anything else on the system :o
It would be nice to see the transmission daemon startup scripts support these 2 features by default. I'll have to remember to make these changes anytime transmission is updated in ipkg. _________________ Linksys WRT610N v2 (DD-WRT) :: D-LINK DIR-825 (OpenWrt) :: The World in 35mm :: Bandwidth Shaping with DD-WRT
