Two points that i want to make clear: 1. By rebooting, i mean that i have to reboot the RedHat box serving the movie to solve the problem. Only after a clean reboot without running adsl-start does the movie play back smoothly. 2. Not even adsl-stop will fix the network slowdown. Rebooting seems like the only way. strange, i cannot reproduce this problem. it works for me here please check if you run adsl-start in debugging mode? How could it work if you only type adsl-start? Do you have DSL configuration under /etc/ppp/pppoe.conf i recommend you should use ifup/ifdown to start/stop DSL connection instead adsl-start/adsl-stop adsl-start is not running in debug mode, no. Yes, i have my configuration in /etc/ppp/pppoe.conf. I'm not sure how to use ifup/ifdown. I can't seem to find any information on it. Could you point me to a resource on the web? Why isn't adsl-start/adsl-stop the best way to connect/disconnect? The HOWTO on rp-pppoe's website doesn't mention ifup/ifdown at all, only adsl-start. I don't know what other information i can give you. I just upgraded to rp-pppoe 3.2-3 to try it again, started playing a movie over the network (it's running fine and smooth), typed adsl-start, and within a few seconds my network has now slowed to a crawl again, the movie stuttering. I've downgraded to 2.6-5, run adsl-start adsl-stop, tried ifdown eth0 then ifup eth0, and the problem persists. What else can i try apart from rebooting? By the way, 'top' shows 94- 97% idle CPU time. we have a new config tool 'redhat-config-network' in 7.2, which allows you to setup your network/dialup/DSL ... This new config tool puts all the configuration fies under /etc/sysconfig/network-scripts/ (for DSL /etc/sysconfig/network-scripts/ifcfg-ppp0) To start/stop DSL connection just do ifup/ifdown ppp0 could you please give me your /etc/ppp/pppoe.conf?

Configuration file for RP-PPPoE
I tried the redhat-config-network tool, and then did ifup ppp0 with rp-pppoe 3.2 and i still had the same problems. By the way, does it matter that i am using the same ethernet card for both ADSL and my LAN? I have set up eth0 as 192.168.3.1, and ADSL to use eth0, and i am doing the tests on eth0/192.168.3.1. of course the network slow down drastically if you use the same ethernet card for both ADSL and LAN ! In normal case it won't work! To fix this problem you have to have 2. network adapter for your DSL But why does RP-PPPoE 2.6 work fine, and 3.2 doesn't? And why, even when i adsl- stop/ifdown, does the network remain slow and bugged? This shouldn't happen and it points clearly towards a bug in 3.2. I should be able to use LAN and ADSL via the same ethernet card. The ethernet card is 100Mbps FD plugged into a 100Mbps FD switch with the ADSL modem on the switch's uplink. Even with ADSL downloading at its maximum speed (512Kbps mine is), i should still get (and do get with RP-PPPoE 2.6) ~9+MB/s via the LAN. It works! There is no slowdown on my network after running adsl-start. The movie is still running smoothly and ftp is getting 8.5-9.5MB/s, even while downloading at maximum speed via ADSL. Great! Thanks! I wonder what the problem with 3.2 was? |
