Red Hat Bugzilla – Bug 8523
plip configures properly but fails to pass packets back
Last modified: 2009-03-13 16:34:54 EDT
Note computer A and computer B are identical. They both
have bidirectional parallel ports correctly configured, as
1). Kernel 2.2.12-20 i386
2). Stock out of the box RH 6.1 install
3). parport module loaded
4). parport_pc io=0x378 irq=7 dma=7 loaded
5). plip parport=0 module loaded
6). computer A-ifconfig plip0 192.168.1.1 pointopoint 192.168.1.2
7). computer B-ifconfig plip0 192.168.1.2 pointopoint 192.168.1.2
8). computer A-route 192.168.1.2 0.0.0.0 255.255.255 UH plip0
9). computer B-route 192.168.1.1 0.0.0.0 255.255.255 UH plip0
10). there are no plip timeout errors
11). ping never responds on either machine
12). tcpdump -i plip0 shows that the packets are getting
through, with an ``icmp: echo request'' but no reply. This is
the case on both machines.
13). netstat -i also shows the expected count on RX-OK for both
boxes, no errors or overruns.
So...there's no problem with the packets getting to each box...
it's as if the packets aren't dispatched thereafter.

Could you tell which packages need to be updated?
(I guess it's the kernel, because I installed all updates).
Also: are you sure this is a duplicate of bug 8624?
