First post to this list... This is LONG, and for that I apologize,but I'm out
of ideas and I want to include sufficient detail. I'll behugely grateful for
any tips or pointers in the right direction.
I cannot get ssh to work over IPv6 between two IPv6-enabled FC4 hostson my home
network, each configured with site-local IPv6 addresses. Irepeatedly encounter
TCP checksum errors (described in detail below).
Things I've tried so far:
* kernel 2.6.13-1.1532_FC4 (server and client)* kernel 2.6.13-1.1456_FC4
(server and client)* kernel 2.6.12-1.1390_FC4 (server and client)* kernel
2.6.12-1.1369_FC4 (server and client)* ssh v4.2p1 rpm from fedora.redhat.com*
ssh v4.2p1 source from openssh.org (Note 1)* usagi telnetd/telnet/inetd source
(Note 2)* usagi telnetd/telnet/inetd rpm packages (Note 2)
Note 1: I had to build openssh4.2p1 with the zlib check turned offbecause
Fedora still uses version 1.2.2.2. (Could this cause what I'mexperiencing?)
Note 2: I tried using the usagi stuff just to have SOMETHING toverify whether
TCP over IPv6 would work at all, but I had problemseither building or
installing. Building the source resulted in oneerror after another. After
fixing a half dozen or so, I finally gaveup. Using the rpm, I found the
binaries were so old (circa 2002),they were incompatible with my OS. Finding
an IPv6-enabled telnet isharder than I thought it'd be; I still don't have one.
What DOES work: I can ping6 either host from the other host. traceroute6 works
between the hosts. Also, a simple IPv6 TCPclient-server application from
Stephens "Unix Network Programming Vol.1" works just fine; the client issues a
connect, and the serverresponds with the output of the "date" command. This
little programis important to me because it indicates that TCP over IPv6 works
in atleast one instance, thus clearing the kernel of suspicion (I think).
Okay, on to the ssh problem... The client in this case is an FC4x86_64 running
2.6.13-1.1532_FC4, and the server is an FC4 i386 alsorunning 2.6.13-1.1532_FC4,
although the problem occurs no matter whichsystem is client or server. Both
systems are running openssh4.2p1-fc4.1 from the Fedora updates-released repo.
In the stuff thatfollows, the client and server can be identified by the last 4
digitsof their respective IPv6 addresses as follows:
client: 9069server: 6dda
Basically, what's happening is the client and server execute the TCP3-way
handshake in frames 3, 4, and 5. Then in frame 6 the serverasserts its ssh
protocol preference (protocol 2), to which the clientacks in frame 7. In frame
8 the trouble begins. The client assertsthat it, too, can speak protocol 2,
but that frame suffers a TCPchecksum error. Frames 9, 10, 11, 13, 14, 15, 16,
17, and 25 areretransmissions of frame 8, each bearing a checksum error.
Oddly, the"incorrect" checksum value remains constant at 0x5d72, while
the"should be" value is all over the map. At frame 32 the server throwsup its
arms in dismay and issues a FIN,ACK and closes the connection.
