Prajem prijemny den,

tak som zacal skusat X-terminaly podla literatury na adrese
http://www.linuxworld.com/site-stories/2001/0823.xterminal.html

(pouzivam RedHat 7.1 s XFree 4.x)

Nastavil som Linux - server, vyskusal ping, bezi. Server ma adresu
192.168.10.129, klient 192.168.10.137.

Na strane servera som upravil subory:
-  /etc/X11/xdm/Xaccess
- /etc/X11/xdm/xdm-config

rebootol som server a spustil xdm, aby bezalo.

Na strane klienta som najprv spustil startx a spravne sa zobrazila sa
seda obrazovka (a xterm). Ukoncil som X-y.

Zadal som prikaz:

    /usr/X11R6/bin/X -query 192.168.10.129      co je adresa toho
servera

a nabehla len seda obrazovka, ale bez loginovacieho okna.

Na konzole vypisuje toto hlasenie:

Audit: Thu Feb 21 17:58:25 2002: 732 X: clent 1 rejected from IP
192.168.10.129 port 32770
Auth name: MIT-MAGIC-COOKIE -1 ID: -1

{takto vyskusa niekolko portov, napr 32771,32772,32773 a 32774 a skonci
s tuto hlaskou}

Fatal server error:
XDMCP fatal error: session failed Session 170640001 failed for display
192.168.10.137:0: Cannot open display
(^^^^^^^^^^^^ je IP klienta)

Pre istotu prikladam aj spominane subory:

Ak mozete, pomozte!

Vdaka a ostavam s pozdravom

#
# Access control file for XDMCP connections
#
# To control Direct and Broadcast access:
#
#	pattern
#
# To control Indirect queries:
#
# 	pattern		list of hostnames and/or macros ...
#
# To use the chooser:
#
#	pattern		CHOOSER BROADCAST
#
# or
#
#	pattern		CHOOSER list of hostnames and/or macros ...
#
# To define macros:
#
#       %name		list of hosts ...
#
# The first form tells xdm which displays to respond to itself.
# The second form tells xdm to forward indirect queries from hosts matching
# the specified pattern to the indicated list of hosts.
# The third form tells xdm to handle indirect queries using the chooser;
# the chooser is directed to send its own queries out via the broadcast
# address and display the results on the terminal.
# The fourth form is similar to the third, except instead of using the
# broadcast address, it sends DirectQuerys to each of the hosts in the list
#
# In all cases, xdm uses the first entry which matches the terminal;
# for IndirectQuery messages only entries with right hand sides can
# match, for Direct and Broadcast Query messages, only entries without
# right hand sides can match.
#

*					#any host can get a login window

#
# To hardwire a specific terminal to a specific host, you can
# leave the terminal sending indirect queries to this host, and
# use an entry of the form:
#

#terminal-a	host-a


#
# The nicest way to run the chooser is to just ask it to broadcast
# requests to the network - that way new hosts show up automatically.
# Sometimes, however, the chooser can't figure out how to broadcast,
# so this may not work in all environments.
#

*		CHOOSER BROADCAST	#any indirect host can get a chooser

#
# If you'd prefer to configure the set of hosts each terminal sees,
# then just uncomment these lines (and comment the CHOOSER line above)
# and edit the %hostlist line as appropriate
#

#%hostlist	host-a host-b

#*		CHOOSER %hostlist	#
