Re: Ethernet connection

With the help coming from the present mailing list, I managed to connect my
laptop with my old desktop PC via a cross ethernet cable, and to make them
communicate via ping and transfer files using rsync.

Today, strangely, on the laptop, instead of

# ifconfig
eth1      Link encap:Ethernet  HWaddr 00:03:0D:33:02:17
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0
          inet6 addr: fe80::203:dff:fe33:217/64 Scope:Link

          collisions:0 txqueuelen:1000
          RX bytes:0 (0.0 b)  TX bytes:468 (468.0 b)
          Interrupt:201 Base address:0xd800

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:86 errors:0 dropped:0 overruns:0 frame:0
          TX packets:86 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:9358 (9.1 KiB)  TX bytes:9358 (9.1 KiB)

I got:

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

          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

, and any connection with the cross cable was impossible.  Also, the command
`ifconfig eth1 192.168.0.1 netmask 255.255.255.0 up' gave:

# ifconfig eth1 192.168.0.1 netmask 255.255.255.0 up
SIOCSIFADDR: No such device
eth1: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
eth1: ERROR while getting interface flags: No such device


Then I did:

 # ifconfig eth0 192.168.0.1 netmask 255.255.255.0 up

, and then `ifconfig' gives:

# ifconfig
eth0      Link encap:UNSPEC  HWaddr 00-03-0D-53-25-5C-86-16-00-00-00-00-00-00-00-00

          collisions:0 txqueuelen:0
          RX bytes:8352 (8.1 KiB)  TX bytes:8352 (8.1 KiB)

, but the connection fails:

$ ping 192.168.0.3

, where 192.168.0.3 is the PC's address.

Please help with issue

Thanks
