Description Steffen Mann 2005-01-05 06:44:22 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5)
Gecko/20041115 Firefox/1.0

Description of problem:
telnet client and server are both the above version both fully up2date
RHEL3 systems.

/etc/sysconfig/i18n:

LANG="de_DE.UTF8"   #"en_US.UTF-8"
SUPPORTED="de_DE.UTF-8:de_DE:en_GB.UTF-8:en_GB:en:en_US.UTF-8:en_US:en:en_US.UTF-8:en_US:en"
SYSFONT="latarcyrheb-sun16"

on the Server side:

LANG="de_DE.UTF-8"
SUPPORTED="en_GB.UTF-8:en_GB:en:de_DE.UTF-8:de_DE:de"
SYSFONT="latarcyrheb-sun16"


However this should not matter the telnet client does not take the
caracters like ����� and pass them on the the server during a normal
logon scession.


Version-Release number of selected component (if applicable):
telnet-0.17-26

How reproducible:
Always

Steps to Reproduce:
1.telnet ip
2. log on a user
3. type caracter like ������ 
    

Actual Results:  diffrent caracters than the expected ones.

Expected Results:  Should pass on these typed caracters.

Additional info:

Tested on two RHEL3 fully up2date systems.

From the duped bug:
The weird looking characters should be german umlauts like the special
characters for ae oe ue and sz.
Comment 3 Sven Borkert 2005-01-06 05:11:16 EST
It seems to me that this is a problem with the telnet client only?
When using a windows telnet client I don't get the problem, it only
appears when makeing a telnet between two Red Hat machines.
Comment 4 Harald Hoyer 2005-01-10 05:01:12 EST
could you please provide the output of:
$ which telnet
Comment 5 Harald Hoyer 2005-01-10 05:07:15 EST
Can your X-Terminal (xterm, konsole, gnome-terminal) display the
Umlauts correctly? Does "ssh" work?
Comment 6 Steffen Mann 2005-01-10 05:10:48 EST
Harald;
[root@smann redhat]# which telnet
/usr/kerberos/bin/telnet
[root@smann redhat]#

ssh does work, even windows telnet clients do.
Gnome-terminal do display the Umlauts correct.

Comment 7 Sven Borkert 2005-01-10 05:14:28 EST
which telnet
/usr/kerberos/bin/telnet

Interesting. /usr/bin/telnet does not have the Problem. Everything
else works correctly.
Comment 8 Harald Hoyer 2005-01-10 05:59:15 EST
reassigning to kerberos
Comment 9 Nalin Dahyabhai 2005-03-02 12:05:07 EST
Telnet is stripping off the high bit of characters you're inputting
before sending them because the telnet binary option hasn't been
negotiated.  I'm not actually sure yet that this is a bug, because the
telnet specs default to treating options which haven't been negotiated
as if they were disabled.

Either way, passing "-8" to telnet on the command line should force
the telnet binary option to be negotiated, which will give you the
results you're expecting.
Comment 13 Nalin Dahyabhai 2005-09-29 13:41:00 EDT
Closing because the telnet client is obeying the protocol specs, and there's a
command-line option which provides the desired behavior.
