Dotaz: Can't open display: localhost:10.0; pod root ide OK

[robob]

Zdravim, na jednom zo serverov mam problem (na ostatnych to ide) so spustenim lubovolnej vzdialenej x-aplikacie. Kazda skonci s hlaskou: Can't open display: localhost:10.0. Ak sa na vzdialenom serveri prihlasim ako root, tak sa aplikacia normalne spusti a vystup ide (ako zvycajne) na klienta. X11 forwarding mam v sshd_config na YES a prihlasujem sa cez ssh -XC uzivatel@vzialeny_server. Viete mi prosim niekto poradit v com je problem? Toto sa mi este nikdy nestalo.

Vdaka

Pusti ssh s parametrom -v alebo -vv a porovnaj. Malo by tam byť niečo o tom, že sa nastavuje remote display a požaduje X forwarding.

[rastos]

ssh -v:

...
Enter passphrase for key '/home/rastos/.ssh/id_dsa':
debug1: read PEM private key done: type DSA
debug1: Authentication succeeded (publickey).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: Requesting X11 forwarding with authentication spoofing.

ssh -vv:

...
Enter passphrase for key '/home/rastos/.ssh/id_dsa':
debug1: read PEM private key done: type DSA
debug2: we sent a publickey packet, wait for reply
debug1: Authentication succeeded (publickey).
debug1: channel 0: new [client-session]
debug2: channel 0: send open
debug1: Entering interactive session.
debug2: callback start
debug2: x11_get_proto: /usr/bin/xauth -f /tmp/ssh-OvbRN24262/xauthfile generate :0.0 MIT-MAGIC-COOKIE-1 untrusted timeout 1200 2>/dev/null
debug2: x11_get_proto: /usr/bin/xauth -f /tmp/ssh-OvbRN24262/xauthfile list :0.0 2>/dev/null
debug1: Requesting X11 forwarding with authentication spoofing.
debug2: channel 0: request x11-req confirm 0

Hm, z nejakého dôvodu to v tomto momente nefunguje ani mne. Remote programy sa sťažujú na BadDrawable a BadWindow errory od X-ov. Ale to bude imho niečo iné ako u teba.

mam tam toto:

.....


debug1: channel 0: new [client-session]                                                   
debug2: channel 0: send open                                                              
debug1: Requesting no-more-sessions@openssh.com                                           
debug1: Entering interactive session.                                                     
debug2: callback start                                                                    
debug2: x11_get_proto: /usr/bin/xauth  list :0.0 2>/dev/null                              
debug1: Requesting X11 forwarding with authentication spoofing.                           
debug2: channel 0: request x11-req confirm 0                                              
debug2: client_session2_setup: id 0                                                       
debug2: channel 0: request pty-req confirm 1                                              
debug2: channel 0: request shell confirm 1                                                
debug2: fd 3 setting TCP_NODELAY                                                          
debug2: callback done                                                                     
debug2: channel 0: open confirm rwindow 0 rmax 32768                                      
debug2: channel_input_status_confirm: type 99 id 0                                        
debug2: PTY allocation request accepted on channel 0                                      
debug2: channel 0: rcvd adjust 2097152                                                    
debug2: channel_input_status_confirm: type 99 id 0                                        
debug2: shell request accepted on channel 0                                               
 

a potom viacero rovnakych riadkov

debug2: channel 0: request window-change confirm 0
                  debug2: client_check_window_change: changed
......

No nie som z toho mudry. Nic taketo nemam:

x11_get_proto: /usr/bin/xauth -f /tmp/ssh-OvbRN24262/xauthfile generate :0.0 MIT-MAGIC-COOKIE-1 untrusted timeout 1200 2>/dev/nul

1. Skus smazat soubor ~/.Xauthority na počítači, kam se připojuješ.

2. Zkus přidat do /etc/ssh/ssh_config řádek: ForwardX11Trusted yes

Toto nepomohlo

[pht]

ssh -Y místo ssh -X

[robob]

Ani toto nepomohlo.

Kedze to bola nova instalacia a predpokladam, ze sa nieco "zmrvilo" pocas nej (zrejme v nejakom subore zle nastavene prava/vlastnik), urobil som ju nanovo. Bolo to ovela rychlejsie ako celodnove hladanie "v com je pes zakopany". Presiel som rozne fora na nete a nic z toho co som skusal nepomohlo. /etc som mal zalohovany, tak som prekopiroval dolezite subory naspat a po 20 minutach instalacie a konfiguracie ide vsetko uplne normalne; niekedy je to najschodnejsia cesta.

Dakujem vsetkym.
