 Posted: Thu Jun 02, 2005 12:16 am Post subject: Network problem route or dns? |
 |
|
Im having some problem these last 2 weeks here...
When I try to load any page mozilla take about 1 minute to resolve the address.. once resolved, to browse anything inside that IP is fast. If I try to browse more than one page at same time, its delay is progressive... (its not a mozilla problem.. but between all my browsers, this was the worst response times).
So I think that can be one of the two: DNS problem or Route problem.
On windows my browsing is very fast.
Here is some configuration mine:
| Code: |
darkbrain fungos # ifconfig
eth0 Link encap:Ethernet HWaddr 00:E0:7D:F4:4C:14
inet addr:10.0.0.1 Bcast:10.0.0.255 Mask:255.255.255.0
inet6 addr: fe80::2e0:7dff:fef4:4c14/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:82740 errors:0 dropped:0 overruns:0 frame:0
TX packets:62891 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:82035635 (78.2 Mb) TX bytes:5505986 (5.2 Mb)
Interrupt:11 Base address:0x8000
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
inet6 addr: ::1/128 Scope:Host
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:5204 errors:0 dropped:0 overruns:0 frame:0
TX packets:5204 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:2070472 (1.9 Mb) TX bytes:2070472 (1.9 Mb)
darkbrain fungos # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.0.0.0 * 255.255.255.0 U 0 0 0 eth0
loopback localhost 255.0.0.0 UG 0 0 0 lo
default adsl 0.0.0.0 UG 0 0 0 eth0

when I execute route it takes about 10s-20s to show the first entry.
when I ping some site, like www.google.com it takes 10-20s too to show the first icmp response, and about 5s for each other, but giving ~175ms each response. If I ping IP direct it is very fast.
Im the only computer in my network turned on when doing these tests, and in windows my browsing is very fast (no changes made on adsl modem confs).
Thanks.. |

Well, you mentioned wondering whether it was DNS or routing, so you should also include your DNS info from /etc/resolv.conf. It could just be that your DNS servers are slow... try emerging net-dns/bind-tools if you haven't already, and run some comparisons on various public nameservers:
| Code: |
dig gentoo.org any
dig @otherguy.gte.net gentoo.org any
dig @dns01.jdc01.pa.comcast.net gentoo.org any
dig @ns1.darpa.mil www.darpa.mil any
|
(the first one will be your nameservers from /etc/resolv.conf ; the last one is a known-insanely-fast nameserver. The middle two are in-between.)
If all four digs take a noticeable amount of time, it's a routing problem. If only the first dig takes a while, it's a DNS problem.
Incidentally, what is this "adsl" host in your routing tables? Do you have that set up in /etc/hosts?

Its a route problem!
All digs delayed about 10s-20s to reply, and the last dig (that fast) was the worst one lol .. about 30s!!!!!
Yes, that adsl is in my hosts... see:
| Code: |
darkbrain fungos # cat /etc/hosts
127.0.0.1 localhost
10.0.0.138 adsl
|
What is happening here? I cant see nothing wrong in that routes...
Any known problem that has this effects? Anything?
