I have internet connection with 1,7 mbit down and 512 kbit up currently serving several corporate/college labs, which is fully loaded most of the time. in my shaper box located in remote site, I have my HTB tcscript that simply creates the qdiscs, classes and filters upon execution. I also have a script (tcstop) containing: rmmod sch_htb rmmod sch_sfq rmmod cls_u32 tc qdisc del root dev eth0 tc qdisc del root dev eth1 for releasing the traffic control. problem is : I need to make changes to my start script, so I execute the tcstop script, edit the tcstart script a little, execute it, and boom. My shaperbox disconnected from the rest of the net. since my shaperbox is placed right before the gateway/WAN router, we all got disconnected. when I came to the shaperbox, it didn't crash or hang, it is just disconnected. and I couldn't find any suspicious log related to that. It didn't happen all the times (about 1 out of 5) but quite annoying. anyone have any idea about that? because I still can't figured out why. __________________________________________________ Do You Yahoo!?
