Hello,
I'm running K5b5 versions of rlogin and rlogind on AIX 4.1 and 3.2 machines,
when there is a very light load on the system they run fine, but when I connect
to larger server systems that handle mail/nfs/etc... with loads around 10-20,
the connection becomes useless. Not only does it take forever to connect, but
individual keystrokes are extremely painful (respone measured in minutes
sometimes), etc... I realize that the only "kerberos" transaction takes place
during the initial connection, and this is a problem more with the
rlogin/rlogind source distributed with the Kerberos distribution, not a problem
with Kerberos itself...
This isn't the type of poor performance you would see with a loaded system, it
is much more extreme. If I connect via normal rlogin or telnet I don't have
this problem, and no I am not connecting with -x (this is *not* an encrypted
session).
Before I start digging in further has anyone noticed this type of problem
before (is it possibly fixed in the next beta for example).
Also has anyone gotten the kerberos version of telnet working under AIX - I
would like to try that to see if I notice similar results, but have been unable
to get it compile so far...
