[1.] One line summary of the problem: plip module on 2.6.x {where
x=8,10,11} fails to transfer data
[2.] Full description of the problem/report:
I've successfully used rsync to transfer files over a plip
connection via a cable connecting the parallel ports of my desktop and
laptop, using kernel 2.4.27.
Now, I'm trying to use kernel 2.6.8 (also failed with 2.6.10 and
2.6.11) and rsync won't
establish a connection.
root #: rsync mydesktop::
rsync: failed to connect to mydesktop: Connection refused (111)
rsync error: error in socket IO (code 10 at clientserver.c(99)
I'm guessing the problem is the ipv6 in 2.6.x. For 2.6.x, ifconfig
shows an inet6 line that isn't there under 2.4.27:
under 2.4.27:
plip0 Link encap:Ethernet HWaddr FC:FC:C0:A8:01:01

with 2.6.x:

Interrupt:7 Base address:0x378
In fact, I can't even ping with this. So, I thought I'd try to
disable ipv6 on this link. I added 'del 192.168.1.2' at the end of my
ifconfig to disable ipv6 (per man ifconfig) and now get:
root #: ifconfig
plip0 Link encap:Ethernet HWaddr FC:FC:C0:A8:01:01

UP POINTOPOINT RUNNING NOARP MTU:1500 Metric:1
Interrupt:7 Base address:0x378
Apparently, the plip0:0 listing is the subtraction of ipv6. Now I can
successfully ping:
root :~# ping -c1 192.168.1.2
PING 192.168.1.2 (192.168.1.2) 56(84) bytes of data.

1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.144/0.144/0.144/0.000 ms
'man rsync' says to add '-4' to the options to get the daemon to use
ipv4, and I did this in /etc/defaults/rsync and it works:
root :~# ps aux |grep rsync
root 8349 0.0 0.3 1912 672 ? Ss 11:02 0:00
/usr/bin/rsync --no-detach --daemon --config/etc/rsyncd.conf -4
However, when I try rsync with or without the '-4' option, on my
laptop, it still fails:
root #: rsync -4 mydesktop::
rsync: failed to connect to mydesktop: Connection refused (111)
rsync error: error in socket IO (code 10 at clientserver.c(99)
When I look in my /var/log/rsyncd logfile on the host, there is no
entry for the attempted connection.
I went back to my original ifconfig, and tried rsync with the '-6'
option, but it also failed.
This makes rsync unusable on 2.6.8/10/11 for me.
