destination host unreachable

mundacho · 03-10-2006, 06:23 AM

hello guys,

I've already read the posts concerning this problem and none of them solve my problem. I've just installed Mandrake 10.1 with an intel board D945GNT. The board has an integrated card I planned to use but I got this error "Destination host unreachable". The driver supposed to work with that card didn't work (the driver e100 from intel, which was included with my distro). So I installed another card than mandrake recognized as Davicom Ethernet100/10 MBit. Everything seems ok at the driver, but I still get the same error.
I give the output of some commands I performed, in the order I executed them:

I read it could be the firewall

Code:

[root@cusipsrv root]# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

but it seems ok to me, here is the ifconfig output

Code:

[root@cusipsrv root]# ifconfig
eth0      Lien encap:Ethernet  HWaddr 00:80:AD:86:69:F0
          inet adr:192.168.100.10  Bcast:192.168.100.255  Masque:255.255.255.0

          collisions:0 lg file transmission:0
          RX bytes:96238 (93.9 Kb)  TX bytes:96238 (93.9 Kb)

then i do some pings

(to my IP, everything ok)

Code:

[root@cusipsrv root]# ping 192.168.100.10
PING 192.168.100.10 (192.168.100.10) 56(84) bytes of data.

(then to the router for example)

Code:

[root@cusipsrv root]# ping 192.168.100.1

, pipe 3

another ifconfig

Code:

[root@cusipsrv root]# ifconfig
eth0      Lien encap:Ethernet  HWaddr 00:80:AD:86:69:F0
          inet adr:192.168.100.10  Bcast:192.168.100.255  Masque:255.255.255.0

          TX packets:1131 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 lg file transmission:0
          RX bytes:106064 (103.5 Kb)  TX bytes:106064 (103.5 Kb)

As someone already showed me, there are no packets transmitted by the eth0 interface... weird, isn't it?

now the route command

Code:

[root@cusipsrv root]# route -n
Table de routage IP du noyau
Destination     Passerelle      Genmask         Indic Metric Ref    Use Iface

0.0.0.0         192.168.100.1   0.0.0.0         UG    0      0        0 eth0

also performed this command grep -e eth0 /var/log/syslog

Code:

Mar 10 11:49:35 cusipsrv kernel: eth0: Davicom DM9102 at pci06:03.0, 00:80:ad:86:69:f0, irq 11.

I taugh it could also be something with the card resetting every moment, but... if it's something with the card, why did I have the same problem with the other card? Any idea?

I hope you can help, thanks in advance for your time,

Maybe a hardware problem? You could try with another Ethernet cable for example. Also, one thing you could do is try a Live CD with a good hardware detection script like Kanotix, just to see if it works there.
