Even though my two machines (a laptop and a desktop) plip
interfaces seems to be configured and connected correctly,
ping between them fail. Can someone help me to fix this
problem?
Here are the details about my configuration:
root@desktop /root]# cat /etc/conf.modules
alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=7
Laptop has the same conf.modules, but it is not starting plip
until I type "insmod plip". Notice printers work fine in both
machines right after booting. Both parallel ports are in ECP mode.
[[root@desktop /root]# lsmod
Module Size Used by
plip 8648 1
parport_pc 5624 1
parport 7124 1 (autoclean) [plip parport_pc]
lsmod in both machines is very similar.
Interface configuration is this:
[[root@desktop /root]# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:3924 Metric:1
RX packets:34 errors:0 dropped:0 overruns:0 frame:0
TX packets:34 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
plip0 Link encap:Ethernet HWaddr FC:FC:C0:A8:00:80
inet addr:192.168.0.128 P-t-P:192.168.0.127
Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
RX packets:28 errors:0 dropped:3 overruns:0 frame:0
TX packets:21 errors:5 dropped:0 overruns:0 carrier:5
collisions:0 txqueuelen:10
Interrupt:7 Base address:0x378
ifconfig is very similar in both, but it has 128 instead of 127
and vice-versa.
Routing is like this:
root@desktop /root]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.127 * 255.255.255.255 UH 0 0 0 plip0
127.0.0.0 * 255.0.0.0 U 0 0 0 lo
Ince again, the laptop has a 128 in place of the 127 in the desktop.
Ping on this side of the interface works fine, but ping to the
other side loses 100% of the messages. I'm using a laplink cable.
Please help me. I'm kind of lost with this 2.2.12-20 kernel of my
RedHat 6.1 distribution.
TIA.
