Time for another one of these threads -- it seems like every distro's forums has one. I've encountered this on linux machines before. DNS lookup is slow. nslookup fails 90% of the time, and browsing the web is painfully slow. I'm fairly certain the problem lies with DNS lookup at this point. I'm using the basic Linpus install. Most people say that ipv6 is the culprit and to disable it. this is done by putting some lines into /etc/modprobe.conf.local to disable ipv6. however, /etc/modprobe.conf nor /etc/modprobe.conf.local do not exist. All I can find are /etc/modprobe.d/modprobe.conf.dist -- can someone verify that this is Linpus's true modprobe local configuration file? Although, considering my luck, I still won't have fast lookups after changing the conf.
Update: - Disabled all ipv6 features in firefox about:config. Enabled http pipelining. No difference in responsiveness. - Added in my DNS servers manually in Network settings instead of making it grab the servers from DHCP. No difference. - Added in the following to /etc/modprobe.d/modprobe.conf.dist: alias net-pf-10 off alias ipv6 off Still no difference in the responsiveness of dnslookups. nslookup still says it cannot connect to the server 90% of the time, the other 10% it takes a long while but does return with a successful lookup. If this doesn't clear up I might end up installing ubuntu, or worse, Windows.
Update: Looks like the issue is with my University's network and not my Aspire. I took it to a different network and it works fine. This particular network just has trouble with Linux machines apparently. They told me a workaround is this: echo 1 > /proc/sys/net/ipv4/neigh/eth0/locktime into /etc/rc.d/rc.local. Does anyone have any idea what this does before I blindly start putting it into config files?
http://linux.startcom.org/docs/he/Introduction to Linux/x8608.html Alternatively you could add it to '/etc/sysctl.conf' like: Code: net.ipv4.neigh.eth0.locktime=1 If you want to test before making the change occur for every reboot, you can do it one of two ways (must be root): Code: echo 1 > /proc/sys/net/ipv4/neigh/eth0/locktime or Code: sysctl -w net.ipv4.neigh.eth0.locktime=1 To check what it is, before and/or after setting it: Code: cat /proc/sys/net/ipv4/neigh/eth0/locktime or Code: sysctl net.ipv4.neigh.eth0.locktime HTH
