With tcpdump data; Re: firefox slow/hang load images and yahoo mail
More data with tcpdump. Visiting www.nytimes.com hanging on 'transferring data from graphics8.nytimes.com' Here is the tcpdump starting when i hit the return on loading nyt.com. The interesting stuff is at the end... It seems to me that we got the name/ip for graphics8.nytimes.com. a) It seems to me that vnsc-pri.sys.gtei.net is not configured correctly? why are we quering that as the nameserver? my /etc/resolve.conf is like this: nameserver 192.168.1.1 nameserver 4.2.2.1 b) i didn't understand the protocol where we are telling vnsc-pri.sys.gtei.net that an udp port is not reachable c) the icpm error ? is this a DNS problem after all? Someone had suggested that there might be a problem with my nic's mtu, however tuning it only marginally helped. I can ping graphics8.nytimes.com, though it turned out to be graphics8.nytimes.m7z.net. rainier# tcpdump -i ipw0 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on ipw0, link-type EN10MB (Ethernet), capture size 96 bytes 01:13:33.954509 IP 192.168.1.101.58733 192.168.1.1.domain: 12832+ ? www.n ytimes.com.

Re: firefox slow/hang load images and yahoo mail
Just checked my gentoo linux setup. The network MTU is at 1500, and I don't run named/bind, and my firefox is setup to do ipv6. The /etc/resolve.conf on my gentoo box is also using 192.168.1.1 as the name server. Don't know why BSD isn't behaving. I have a few guesses: a) my FreeBSD wireless network driver isn't behaving (it's a thinkpad t40's build in card) b) or my router (DLink DI-714) didn't like FreeBSD's network packet -- i don't know enough here Really appreciate any help here.

Eliminated the wireless driver problem, as I connected via LAN to my router and still got the hang and the browers has to be killed. Here is more tcpdum data. It's hanging/repeating itself. Again, none of these problems in my gentoo linux box.

This is the tcpdump when mail.yahoo.com hangs. It kept on sending the same packet to f407.mail.yahoo.com without getting the ack back. Maybe my router has somehow dropped that packet? 16:02:09.376566 IP 192.168.1.101.52367 f407.mail.yahoo.com.http: S 1416997185:1416997185(0) win 65535 mss 410,nop,nop,sackOK,nop,wscale 1,nop,nop,timestamp 445106 0 16:02:12.576613 IP 192.168.1.101.52367 f407.mail.yahoo.com.http: S 1416997185:1416997185(0) win 65535 mss 410,nop,nop,sackOK,nop,wscale 1,nop,nop,timestamp 445426 0 16:02:15.776664 IP 192.168.1.101.52367 f407.mail.yahoo.com.http: S 1416997185:1416997185(0) win 65535 mss 410,nop,nop,sackOK 16:02:18.976713 IP 192.168.1.101.52367 f407.mail.yahoo.com.http: S 1416997185:1416997185(0) win 65535 mss 410,nop,nop,sackOK 16:02:22.176762 IP 192.168.1.101.52367 f407.mail.yahoo.com.http: S 1416997185:1416997185(0) win 65535 mss 410,nop,nop,sackOK 16:02:28.376861 IP 192.168.1.101.52367 f407.mail.yahoo.com.http: S 1416997185:1416997185(0) win 65535 mss 410,nop,nop,sackOK On 4/28/05, benchmark [EMAIL PROTECTED] wrote: Thanks for being kind and patient with me.

firefox slow/hang load images and yahoo mail
Basic info: System 5.3 portupdate last night build firefox 1.0.3 build linuxwrapper, flashplugins, etc. A few problems I noticed: a) firefox is very slow loading any site with images. For example, loading www.nyt.com, the text content comes up very quickly, but then it takes forever to load the images. My question: is this a problem with my graphics or it's firefox? it seemed to me to be a problem with firefox. b) when i try to login in my mail account at yahoo, it just hangs. I checked with my windows xp's firefox loading at the sametime, there were no problems. So it's no the problem with the network connection or the website itself. Is there anything (like plugins, or libraries, etc) that I need to tweak? thanks. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Some of the adservers used on websites don't respond correctly to IPv6 queries, and cause DNS timeouts. Try running bind with the -4 option to disable IPv6, and see whether that helps, and/or try switching to using a different nameserver, if you are using someone elses (ie, your ISP's). -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I have setup dhcp via wireless (ipw driver) for thinkpad. how do you change the name server? and is there anything i need to change in my dhcp setup? My ping on freebsd responds faster than the ping on windows xp, so i think the basic network is working. And i was running dhcp on XP via wireless as well, and it didn't seem to have any problems On 4/26/05, Chuck Swiger [EMAIL PROTECTED] wrote: benchmark wrote: [ ... ] A few problems I noticed: a) firefox is very slow loading any site with images.
