I'm trying to play with Coda in order to do smooth home/laptop
synchronization.

So I got the latest and greatest pre-patch--2.1.120-3, 
coda-4.6.5.tgz and linux-coda-4.7.0 and started compiling.
(It's a bleeding-edge Debian system.)

So I configured the kernel with modular coda support, built it and
friends, then built the linux-coda-4.7.0 module, and installed that
coda.o in place of the 2.1.120-pre-3 one.  (I noticed that
linux-coda-4.7.0 has the 2.1.118 patch to struct file_operations, so
obviously it's quite current.)

Then I built the client programs.  I suppose I should mention
that I added -O to OPTFLAG in coda-4.6.5/Makeconf, since I saw
it was compiling just -g and I found that offensive in such a large
piece of code.  (gcc 2.7.2.3; I'd like to try egcs-1.1, but not until
I get it working first.  gcc found some C++ warnings and egcs
is pickier so might not compile it at all.)

As per the recommendation, I did venus-setup testserver.coda.cs.cmu.edu 25000
(Yes, I have that much free space on /usr), and then ran venus.
No luck.  Reboot, try venus -init.  No luck.

The console fills up with
13:53:04 GetRootVolume: can't get root volume name!
13:53:34 GetRootVolume: can't get root volume name!
13:54:04 GetRootVolume: can't get root volume name!

I keep seeing in tcpdump UDP port codasrv unreachable on
strauss.coda.cs.cmu.edu.  Numerically, do remove one more possible
confoguration error, that's

(I am leaving my own ip address off the public mailing list until I'm
sure I have the system set up securely!)

Stopping venus (fg; ^C) produces the error
Sep  4 14:04:09 colin kernel: coda_get_rootfid: error -4 
Sep  4 14:04:09 colin kernel: coda_read_super: coda_get_rootfid failed with -4 
Sep  4 14:04:09 colin kernel: coda_psdev_write: downcall, no SB! 

And stating it again produces
Sep  4 14:06:56 colin kernel: coda_psdev_write: downcall, no SB! 

Before I go too much further, let me ask... is the test server running
right now?  The port numbers match those in include/ports.h, which
the comment says are the IANA ones.


Of course, thank you so much for all your work making this stuff!
I can't praise it too extravagantly yet, since I haven't tried it.
