Hi. I'm experimenting with IPv6. Earlier, I wrote about tunnel problems, the result of which is I'm waiting to establish the tunnel until I can put a PC in place of the router, and terminate the tunnel there rather than on an internal machine. NAT is a great security shortcut, but it does indeed have its limitations.
This morning (insomnia sucks) I've been trying v6 between my two debian systems, through a Linksys WAP11. The WAP11 is, as far as I can tell, a v4 device only, but it seems to be passing v6 traffic without problems: ==== $ ping6 ::192.168.1.20 PING ::192.168.1.20(::192.168.1.20) 56 data bytes 64 bytes from ::192.168.1.20: icmp_seq=1 ttl=64 time=5.01 ms 64 bytes from ::192.168.1.20: icmp_seq=2 ttl=64 time=5.98 ms 64 bytes from ::192.168.1.20: icmp_seq=3 ttl=64 time=4.05 ms ==== and ==== $ ping6 fef::192:168:1:20 PING fef::192:168:1:20(fef::192:168:1:20) 56 data bytes 64 bytes from fef::192:168:1:20: icmp_seq=1 ttl=64 time=4.94 ms 64 bytes from fef::192:168:1:20: icmp_seq=2 ttl=64 time=4.88 ms 64 bytes from fef::192:168:1:20: icmp_seq=3 ttl=64 time=7.45 ms ==== Ssh also works, but ftp doesn't. I tried command line ftp, lftp, and ftp://fef::192:168:1:20/ inside konqueror, as well as by hostname, and they all say unknown host or malformed url. I didn't find a "ftp6" through dselect, are the ftp clients just not v6 compatible? Lastly, I have a technical question. I addressed the hosts not only with fef::192:168:1:2 and fef::192:168:1:20 but also ::192.168.1.20 and ::192.168.1.2 ==== #ifconfig eth1 Link encap:Ethernet HWaddr 00:02:8A:94:48:01 inet addr:192.168.1.2 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::202:8aff:fe94:4801/64 Scope:Link inet6 addr: fef::192:168:1:2/120 Scope:Global inet6 addr: ::192.168.1.2/120 Scope:Compat UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4107404 errors:0 dropped:0 overruns:0 frame:0 TX packets:3082080 errors:4354 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:721410736 (687.9 MiB) TX bytes:404624912 (385.8 MiB) Interrupt:177 Memory:d4006000-d4006ff ==== Does the "Scope:Compat" confir any automatic functions? Routing, NAT, v6 to v4 conversions? Is it treated as Global or Local address space? I notice that even though "fef::" is considered private, its notation above is "Scope:Global". Or is "Scope:Compat" just notated as "Compat" for human readability? Darned Second-System syndrome.
