Kerberized telnet is supposed to determine the appropriate kerberos
realm to use from a connection based on the domain name of the host,
in concert with krb.realms. This functionality is osensibly done with
krb_realmofhost in telnet/libtelnet/kerberos.c.
It appears to be broken under 8.0E:
[bart-savagewood!jhawk] ~> which telnet
/usr/athena/bin/telnet
[bart-savagewood!jhawk] ~> telnet -ax panix2.panix.com
Trying 198.7.0.3...
Encryption is verbose
Connected to panix2.panix.com.
Escape character is '^]'.
[ Trying KERBEROS4 ... ]
mk_req failed for rcmd.panix2@ATHENA.MIT.EDU: Principal unknown (kerberos)
Whereas specifying the realm explicitly:
[bart-savagewood!jhawk] ~> telnet -axkPANIX.COM panix2.panix.com
Trying 198.7.0.3...
Encryption is verbose
Connected to panix2.panix.com.
Escape character is '^]'.
[ Trying KERBEROS4 ... ]
[ Kerberos V4 accepts you ]
or using the telnet from the telnet locker:
[bart-savagewood!jhawk] ~> /mit/telnet/sun4bin/telnet -ax panix2.panix.com
Trying 198.7.0.3...
Encryption is verbose
Connected to panix2.panix.com.
Escape character is '^]'.
[ Trying KERBEROS4 ... ]
[ Kerberos V4 accepts you ]
Both seem to work fine. Cursory inspection of the telnet code doesn't
show anything wrong, so perhaps the kerberos library is broken.
Not having a telnet w/ symbols, I haven't really investigated
much further.
