Hello,
recently I've installed 7.0 and now I'm observing strange thing with my
Internet connection.
Access to some sites may be VERY slow or doesn't work at all with different
kinds of timeout
messages or without messages at all (but other sites works fine). For example,
firefox may say
"Transferring data from..." message and then "The connection to the server was
reset while
the page was loading", lynx just says "HTTP/1.1 200 OK" and displays no data,
etc.
I'm also using Linux and Windows XP on the same machine, and the same sites are
loaded very
quickly. Note I'm not using a proxy.
My NIC is:
mskc0: <Marvell Yukon 88E8053 Gigabit Ethernet> port 0xc800-0xc8ff mem
0xcdefc000-0xcdefffff irq 17 at device 0.0 on pci2
msk0: <Marvell Technology Group Ltd. Yukon EC Id 0xb6 Rev 0x01> on mskc0
msk0: Ethernet address: 00:11:2f:37:d5:19
miibus0: <MII bus> on msk0
e1000phy0: <Marvell 88E1111 Gigabit PHY> PHY 0 on miibus0
e1000phy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX-FDX, auto
mskc0: [FILTER]
And network configuration is:
msk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=19a<TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4>
ether 00:11:2f:37:d5:19
inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
inet 127.0.0.1 netmask 0xff000000
msk0 is DHCP-configured from Linux router, which is connected to ISP via PPPoE:
eth0 Link encap:Ethernet HWaddr 00:01:C0:02:F5:45
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
...
eth1 Link encap:Ethernet HWaddr 00:01:C0:03:0A:66
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
...
ppp0 Link encap:Point-to-Point Protocol
inet addr:X.X.X.X P-t-P:10.0.0.1 Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1
...
Here eth0 is a "transport layer" for ppp0, which is connected to ISP, and eth1
is a local
network interface. The Linux router does a full NAT for all machines from
192.168.1.0.
I've tried to reduce MTU to match router's ppp0 setting with "ifconfig msk0 mtu
1492" and even
down it to 1480, but it doesn't help.
Any ideas ?
Dmitry
