Hello,
I've rented a dedicated root server (SR7 at strato.de) and would like to run qemu at it, but get the error:
# qemu -hda install.img -cdrom install47.iso -boot d Could not initialize SDL - exiting
It seems that I have to establish X connection, so I've installed Xming at my WinXP laptop and at the server I have changed these 3 lines in the /etc/ssh/sshd_config:
X11Forwarding yes X11DisplayOffset 10 X11UseLocalhost yes
And also I have installed these Xorg packages:
# rpm -qa | grep -i xorg xorg-x11-utils-7.1-2.fc6 xorg-x11-drv-evdev-1.0.0.5-5.el5 xorg-x11-drv-vesa-1.3.0-8.2.el5 xorg-x11-filesystem-7.1-2.fc6 xorg-x11-font-utils-7.1-2 xorg-x11-server-utils-7.1-4.fc6 xorg-x11-xkb-utils-1.0.2-2.1 xorg-x11-xfs-1.0.2-4 xorg-x11-fonts-base-7.1-2.1.el5 xorg-x11-drv-keyboard-1.1.0-3 xorg-x11-server-Xorg-1.1.1-48.76.el5_5.1 xorg-x11-drv-mouse-1.1.1-1.1 xorg-x11-drv-void-1.1.0-3.1
Then I've restarted the server and run PuTTY to connect to it, where I have checked the Connection->SSH->X11->Enable X11 forwarding
(Sorry for mentioning all this Windows stuff, but I don't have a Unix desktop and also the problem seems to be in the CentOS config)
When I connect to the CentOS machine, the DISPLAY variable isn't set at all. Shouldn't SSH set it to localhost:10.0 ?
I try to set DISPLAY manually to localhost:10.0 and my_ip_address:0.0 and I have tried connecting as root and as a non-root user.
Still I can't run any X programs like xterm:
$ echo $DISPLAY
$ xterm xterm Xt error: Can't open display: xterm: DISPLAY is not set
$ export DISPLAY=localhost:10.0 $ xterm xterm Xt error: Can't open display: localhost:10.0
$ netstat -an |grep ESTABLISHED (my sshd listens at port 443) tcp 0 52 ::ffff:85.214.XXX.XXX:443 ::ffff:88.153.153.102:2646 ESTABLISHED tcp 0 0 ::ffff:85.214.XXX.XXX:443 ::ffff:88.153.153.102:2566 ESTABLISHED
$ export DISPLAY=88.153.153.102:0.0 $ xterm xterm Xt error: Can't open display: 88.153.153.102:0.0 (after long time)
And the firewall is off:
$ sudo /sbin/service iptables status Firewall is stopped.
And I don't see anything in the Xming log (pasted below).
Does anybody please have a hint for me? My Linux knowledge is a bit rusty :-)
Should I start X somehow at the Linux side? (I've checked chkconfig --list, found nothing there)
Regards Alex
