Title: mandrake 10 : IPV6 ?
Post by: Anonymous on May 13, 2004, 04:11:49 pm: Hi!!

I recently installed Mandrake 10 Official on my pc AND pdaxrom on my zaurus beacause i was fed up with mdk 9.2 and Daniela not being able to talk to each other no matter what i did...

Now, (halleluia) i can ping and even ssh to my C750 !!!

BUT (yes, there is still a \"but\") i can\'t ping _from_ the Z to the PC. I think it might be due to ipv6 as the ifconfig gives me a strange thing (896:vf:456;... something like that... not home for now...).

here is my question : do i have to desactivate ipv6 (wich might be useful later) ot do i only have to change the traditionnal 192.168.129.1 to the ipv6 address?

Thanks in advance.

What ever happened to \"how do I eject my cf card\" and \"how do I change the time\"

My guess is that if ssh is working then two way connections can be established. When you connect to your Z via ssh and issue \"who am I\" what does it report at the end in brackets? can you ping that address?

I have never used IPv6, but I was under the impression that it was fully backwords compatible.

Post by: DrWowe on May 13, 2004, 05:10:54 pm: IPv6 is definately NOT backwards compatible. However, it\'s doubtful that the PdaXRom people compiled a kernel with ipv6 but not ipv4, so that\'s probably not the culprit.

Guest: When you run ifconfig, you shold see both ipv4 and ipv6 addresses. If not, then there\'s a problem.

ehg, another silly question...

the How-to proposes this script :

#! /bin/bash
localIface=eth0
localIp=192.168.1.1
zIface=usb0
zIfaceIP=192.168.129.1
zIP=192.168.129.201

typeset -i num
num=`ifconfig | grep $zIface | wc -l`
if [ $num -eq 0 ] ; then
ifconfig $zIface $zIfaceIP netmask 255.255.255.255 up
route add -host $zIP $zIface
fi
iptables -t nat -F
iptables -t nat -A POSTROUTING -j SNAT -o $localIface --to $localIp
echo 1 ] /proc/sys/net/ipv4/ip_forward

I suppose the
\"localIface=eth0
localIp=192.168.1.1\" thing is to indicate the way to the internet...

BUT (i kind of love this word...) i don\'t use a ethernet interface to connect but a usbmodem...
So, 1) what is my localinterface ?
2) what is my local ip ?

Here is a copy of my ifconfig

I know i should\'nt give my ip that way but, hey, this is a matter of trust

Thanks in advance...

Post by: tecknobabble on May 17, 2004, 03:23:44 pm: Well you have both an eth0 and a ppp0 (this is likely to be the usbmodem)... but both seem to have very similar packet receive/transmitted counts. eth0 is using IPv6 while ppp0 is IPv4.

What does the route show as your default gateway?

In theory once you know which interface is being used as your default gateway you\'ll know the ip-address and interface to use... but if it is eth0 then you\'ll need to install the iptables-ipv6 rpm and use ip6tables instead of iptables.

I changed as you told, tecknobabble, but now, when i try to launch the script, the console keeps answering \"acess denied\", even if i\'m su...

Do i have to do anything else than copying the script into a file and type ./[name_of_the_file]?

Thanks again, and sorry for so much newbieness...
