I recently rebuilt and upgraded a server to Debian testing, and I've got an issue doing X11 forwarding over SSH (Win7 client using Putty and Xming if that makes any difference) -- specifically, any attempt to start an X app via sudo (I've specifically tried xeyes and KVM's virt-manager UI) results in variations on 'PuTTY X11 proxy: Can't open display: localhost:10.0' errors. Googling led me to try extracting and copying MIT-MAGIC-COOKIE-1 values from my regular user's session into root's via a combination of xauth list run as normal user and xauth add run as root. After doing this, X11 forwarding works, but it's a non-optimal solution since the cookie values change each session. Since this worked before the rebuild and upgrade, I'm guessing it's something new or buggy in debian. Is there a good way to work around this?
Hi Rod and all, Thank you so much for your help. I tried what you've suggested. It works! I am so happy for that. But there is still some warnings. What I've done as below: My redhat is a new server running redhat enterprise server 6. There isn't ssh2_config file. So like what I did yesterday, I uncommented a line contains 'X11Forwarding yes' in sshd_conf. Back to Mac, in terminal, type 'xterm&'. In a X terminal, using ssh login to redhad, as Rod suggested. I can login but got two warnings: Warning: untrusted X11 forwarding setup failed: xauth key data not generated Warning: No xauth data; using fake authentication data for X11 forwarding. Although I got those warnings, I still typed xterm& and opened a new xterm which comes from redhat. Then try 'xclock&'. It displayed!! So great! Now, I have an other question. I opened 'firefox' from xterm. Firefox was also booted up, but the letters on menu and top bar were blurred. And the warnings I got were: Xlib: extension 'RANDR' missing on display 'localhost:10.0'. Xlib: extension 'RANDR' missing on display 'localhost:10.0'. Xlib: extension 'RANDR' missing on display 'localhost:10.0'. Have you ever met such problem? This is a new problem. But I already feel so happy that you help me solved a problem which had bothered me for more than three days! Thanks all your help!
Xauth Key Data Not Generated Linux Download
Command and conquer 4 key generator. Warning: No xauth data; using fake authentication data for X11 forwarding. Dead space 1 key generator. Despite of the annoying warning, ssh is working perfectly, even for programs running on X (i.e. If I run gedit, I get the screen to open and I can operate properly with it). After a bit of research in the net, I found out this #00fc## should match my machine's hostname and display number, but somehow, the generation of this key is failing. Has anyone else noticed the same? Not that it is a very worrying matter, but. https://chickeen320.weebly.com/quick-heal-total-security-product-key-generator-2019.html. Someone knows how to fix it? Slender the arrival key generator. I tried to run xauth after logging in, by adding.
