[LON-CAPA-admin] Access Server Problems

[Todd Ruskell]

So, this is a strange one for me.  I'd appreciate any advice.

We just rebuilt an access server, lc1.mines.edu (csma1) with centOS 5. 
As far as I can tell, no errors on install, no missing dependencies. 
loncontrol and httpd start just fine.  I *think* that ports 80, 8080, 
and 5663 should all be open on both machines.  Our other access server, 
csma2 still works fine.

Problem is, my library server can't find csma1.  I'm also pretty sure 
that csma1 can't find the library server, either.  I've included 
relevant output from the access server logs, below, for a representative 
attempt to log in with a kerberos account.  I can't log in with an 
internally authenticated account, either.  I don't get anything on the 
library server logs.

Whenever I attempt to log in, I get "Username and/or password could not 
be authenticated" from my browser.

Now, the funny thing is that csma1 is also in spare.tab, and as soon as 
it came back online it started accepting logins from binghamton (I 
included a couple lines in lonnet.log to show this), including 
authorization.  So csma1 will, in fact, talk to some members of the 
network in some fashion.  Now, I also got a *lot* of "Userfile repcopy 
failed" messages appearing in lonnet.log.  Perhaps that means that I 
don't have full communication?

But, /home/httpd/html/res is populated by resources, presumably from the 
chemistry courses the binghamton users were attempting to access.

I patiently await the word of the almighty gurus.

Thanks,

Todd
