linux - Change maximum number of Virtual interfaces in Kernel -


i running ubuntu server 14.04.3.

i have smcroute installed - version 0.95, build 130523. when attempt start daemon error message: erro: addvif, out of vif space;, happens after attempts add 33rd network interface of machine.

looking in mroute.h in /usr/include/linux/ folder, saw maxvifs defined 32, upped 100 , saved file.

after reboot can still see 32 limit being imposed, file still states 100. how can force os read file?

you need rebuild (and reinstall) kernel modified config. there ubuntu-specific instructions here
