[opensuse-ppc] 11.1 ps3 network/dns issue
Hello, I have been having the strangest network issue as of late. I did not have any problems with openSUSE 11.0, but am having it with 11.1. Any troubleshooting tips would be greatly appreciated. I seem to be getting intermittent problems resolving hosts. I will have trouble trying to update with zypper or browse the web with Firefox. It doesn't fail everytime, so I do not know where to begin to debug. My wireless connection works correctly when using the PS3 under the Game OS. Here is an example of what I am seeing: ps3-linux:~ # host powerpc.opensuse.org powerpc.opensuse.org has address 195.135.221.142 ps3-linux:~ # zypper update Download (curl) error for 'http://powerpc.opensuse.org/distribution/11.1/repo/oss/content': Error code: Connection failed Error message: Couldn't resolve host 'powerpc.opensuse.org' Abort, retry, ignore? [A/r/i]: ^Cps3-linux:~ # ps3-linux:~ # host powerpc.opensuse.org powerpc.opensuse.org has address 195.135.221.142 I am using wlan0 configured via DHCP connecting to a common LinkSys WRT54G wireless router without encryption. Like I mentioned earlier, I used the same setup under 11.0 without a problem. Other computers on my wireless network do not have any trouble. One thing that seemed out of place to me was that the network activity light on the PS3 seems to stay lit when I am not using the network, and blinks when I am. Shouldn't it be off when I'm not using any network functions? Is anybody else seeing that particular issue?

Which nameserver is used by the game os and your 11.0 installation? Maybe the ones used in your resolv.conf are flakey? I use the same router, but with openwrt firmware. It acts as caching nameserver, so I enter the routers ip as dns server and let the router detect the dns setting when connecting to the dsl provider. That has proven to be a stable config.

could you constantly run a ping to powerpc.opensuse.org and see if that times out from time to time while doing 'zypper up'.

I believe I have this issue resolved. Ultimately, it seems to be related to the nameservers from my ISP or some sort of interaction between my router and DNS. Perhaps someone could shed some more light on this if they have solved a similar issue. Here is what I tried: 1. I edited resolv.conf, trying each name server by itself. Of the three name servers, #1 and #2 worked by themselves and I was able to install some zypper packages, while #3 had failures where it couldn't resolv a hostname. Enabling #1 and #2 together unexpectedly also resulted in a failure. I wouldn't consider any of my tests objective, as I don't know how to correctly flush DNS and reload the configuration; I did "/etc/init.d/network restart" between tests. 2. From searching the net, I came across a post that claimed that the Linksys WRT54G router actually runs a nameserver service and may be used as such. Setting my nameserver to the router's IP seems to work well for my configuration. My router is version 8.0 with firmware 8.00.5. This leads me to believe my problem may be some strange Linux/router/DNS interaction. I'm really unsure... if this setup works, I probably will not invest more debugging time in the immediate future. Here is the link to the thread that lead me to set my router as my nameserver: http://creativekarma.com/ee.php/weblog/comments/slow_dns_response_on_linux_w... Lastly, can someone else confirm that the green network activity light stays solidly on when no network activity is occurring? -Mick -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-ppc+help@opensuse.org

"/etc/init.d/nscd restart" flushes the name cache. But I would expect, that failures dont get in the cache. So that would still not explain your failures when using #1 and #2.
2. From searching the net, I came across a post that claimed that the Linksys WRT54G router actually runs a nameserver service and may be used as such. Setting my nameserver to the router's IP seems to work well for my configuration. My router is version 8.0 with firmware
As stated in my other post, I would recommend using this, because it updates the name servers automatically if your isp changes them.
Lastly, can someone else confirm that the green network activity light stays solidly on when no network activity is occurring?
This is the usual bahaviour of network activity leds. Permanent on means link to switch/hub in this direction is ok, but no traffic. Blinking means traffic in this direction. Along with the corresponding led at the switch you get a complete status of the link and traffic. I did not configure ethernet yet (and ifconfig did not list eth0 this morning, only wlan0), so the ps3 might still be the big exception from this.

I had configured WLAN yesterday for a short test and it is the same here: Off when not associated with access point, and permanently on when no traffic. HTH, Joachim P.S.: my ethernet works fine now. Bit strange, but it was just a matter of a reboot. -- To unsubscribe, e-mail: opensuse-ppc+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-ppc+help@opensuse.org
