Hey all, The IUTF8 tty mode support added to the client in 7.3 unfortunately appears to have broken interop with a handful of noncompliant server implementations that immediately close the connection when they are sent an opcode that they know nothing about, rather than ignore it. Setting the value to 0 is not enough...

This flag exists for some time and is available in Linux kernel sinc...

I setup a ssh chroot jail following this[1] guide. It works for my user to login, use ls and use scp which is all I really want. I do have a problem I cannot solve: when connected and navigating the filesystem, the backspace key actually moves the cursor forward and does not delete what I type. I may have found a hint from some googling that readline will read in /etc/inputrc on login but if

When running R from the terminal on Linux (Ubuntu 16.04), it core dumps whenever / wherever I press Ctrl-4 or Ctrl-\. You get thrown back to the terminal with "Quit (core dump)" being the only message. Grepping the R source code, it doesn't look like that message is generated by R itself. Over on Twitter, it has been confirmed to also happen on macOS. $ R -d valgrind --vanilla

I have the following gnome terminal profile settings: Backspace = ASCII DEL Delete Key = Escape Sequence If the logged in session in the terminal window is my own user id then the delete key does nothing. If however, I su -l in the same terminal window then the delete key removes the character under the cursor and left shifts the rest of the line. I am fairly confident that the delete

Hello everyone, recently I've found something I consider a bug. Correct me if I'm wrong, but I always thought that Linux' EOL is 0x0A. Imagine my surprise when I saw that all messages that are being output on to the stderr (on any Linux I've tested - Fedora and Ubuntu) are terminated with 0x0D, 0x0A. Maybe that's standard behaviour of all stderr messages in all Linux
