 |
|
I have installed gentoo 1.4 on my server.
I first build the system without ipv6 support. Now i'm trying to adapt the system for ipv6, which i have native in my University Network (so no tunnel).
I have rebuild my kernel (linux-2.4.19, not the gentoo one) with ipv6 support. Recompiled iputils, nettools and iproute (USE=ipv6).
I get an ip6 number assigned to me and all looks good. Ik can ping6 my server without trouble.
But i cannot ping6 any other ipv6 machine from my server.
At least not when i use 40 or more databytes. When i use 30 or less, everything is fine. Did i forget to recompile anything?
The NIC is a from Farallon and runs on the Tulip driver. I've never in any way experienced any trouble with it.
These are the ping6 results. Does anyone have any clue what is going on here?
| Code: | [otherhost:~] pjotr% ping6 server.ipv6.utwente.nl
PING6(56=40+8+8 bytes) 2001:610:1908:8000:***:****:****:**** --> 2001:610:1908:8000:***:****:****:****

| Code: | server root # ping6 otherhost.ipv6.utwente.nl
PING otherhost.ipv6.utwente.nl(otherhost.ipv6.utwente.nl) 56 data bytes

Now with small databytes
| Code: | server root # ping6 -s 30 otherhost.ipv6.utwente.nl
PING otherhost.ipv6.utwente.nl(otherhost.ipv6.utwente.nl) 30 data bytes
38 bytes from otherhost.ipv6.utwente.nl: icmp_seq=1 ttl=64 time=0.298 ms
38 bytes from otherhost.ipv6.utwente.nl: icmp_seq=2 ttl=64 time=0.275 ms |
Here are some printouts from various tools.

ftp.snt.utwente.nl is an alias for vlaai.snt.utwente.nl.
vlaai.snt.utwente.nl has AAAA address 2001:610:1908:8000:200:1cff:feb6:1503 |
