“ssh -Y” fails moaning “X11 forwarding request failed on channel 0” – solved!
$ ssh -v -Y REMOTE_HOST

debug1: Requesting X11 forwarding with authentication spoofing.
debug1: Requesting authentication agent forwarding.
X11 forwarding request failed on channel 0

I looked around and I found this article:
- https://www.cyberciti.biz/faq/how-to-fix-x11-forwarding-request-failed-on-channel-0/
The article advises to edit /etc/ssh/sshd_config on the remote system:

$ sudo vi /etc/ssh/sshd_config

and to add these lines:

X11Forwarding yes
X11UseLocalhost no

The remote sshd needs reloading, and because the remote system uses systemd, this is how:

$ systemctl restart sshd

Now after a new “ssh -Y” I can start xeyes and it gets displayed on my PC’s Cygwin/X server.

GitLab – the GitHub competitor

As opposed to GitHub (GitHub_Desktop) apparently they do not have a proprietary GUI tool – and propagate it.

cygwin’s cp fails mentioning cygatttr-1.dll

…/opt/cygwin64/bin/cp.exe: error while loading shared libraries: cygattr-1.dll: cannot open shared object file: No such file or directory

I wasn’t able to find a viable fix on the web.

I found a copy of that file in in old installation, and I copied that into the cygwin bin directory – the cygwin64 and the non-64 one – at least for cygwin64 it fails w/o moaning properly, just that it yields exit code 127.

installing Cygwin on Windows without having admin rights
- https://superuser.com/questions/229477/installing-cygwin-on-windows-xp-without-having-the-admin-rights
I like the “-B” (“–no-admin”) command line approach best:

.\setup-x86_64 --no-admin

Oracle SQL Developer – how to run it on Windows in English w/o admin rights?
- https://stackoverflow.com/questions/7768313/how-can-i-change-the-language-to-english-in-oracle-sql-developer
- https://stackoverflow.com/a/24532448/3119172
I chose the approach “set language at runtime“:

sqldeveloper.exe --AddVMOption=-Duser.language=en

Works like a charm.

On the Win7 PC at work I have no admin rights, therefore I cannot change the config file mentioned in the thread.

tramp says: “Cannot find local copy program: pscp” – but that does not mean there is something wrong with your emacs/tramp/PuTTY set-up
Every now and then I come across this error message:

Cannot find local copy program: pscp

This only occurs for “bigger” files (e.g. a 40k file), not for small files, because small files are being dealt with by plink.

tramp-do-copy-or-rename-file-out-of-band (in lisp/net/tramp-sh.el) tries to find the copy-program on exec-path instead of PATH, so we have to add putty-directory to exec-path as well. I amended this page to deal with the situation:

Fixed 😆
