Hi there. I got another problem now. I got a linux router with 4 network interfaces on whose i do traffic shaping with tc tool. I'm constantly changing classes, filters and such. The need to constantly change them will remain even after i finish testing all posibilities. All works fine until the router doesn't get rebooted when i loose all my tc settings. After it comes back i have to make all the changes again and it's REALLY annoying to do so. (You try to reconstruct 50 or more lines of commands in the specific order ;-) ) A simular problem i encontered with iptables, but I solved it with crontab and iptables-save/restore. Is there a simular solution for tc? How do you cope with this problem? One option would be to have a script and constantly change what i do with tc in it to so after a reboot it would come back. But his way i would constantly have to worry about sychronizing the script with the actual changes i make and double my efforts. Please help me. Have a nice day. -Tester
