The problem was indeed my login script, although not to do with requiring a terminal (I’d suspected that and tested with the -t and -T options). The problem was that my .bashrc was running an exec (in this case to zsh – because our system doesn’t allow chsh to zsh). The offending line: test -f … Read more
The easiest way is to download https://packagecontrol.io/Package%20Control.sublime-package using wget or curl, and store it in ~/.config/sublime-text-3/Installed Packages. It will then set itself up upon first starting the editor. As a bonus, if you create ~/.config/sublime-text-3/Packages/User/Package Control.sublime-settings and populate it with the packages you want installed, everything should work more-or-less automatically to download and install everything. … Read more
I figured out: the flag –chmod is a new feature from Docker Buildkit, so it is necessary to run the build enabling it via: DOCKER_BUILDKIT=1 docker build ./ However, it is really not clear why Docker swallows the –chmod option without any error or warn about the non-existing option 😕.
POSIX threads (pthread) is not an implementation, it is a API specification (a standard, on paper, in english) of several functions whose name starts with pthread_ and which are defined in <pthread.h> header. POSIX is also a set of specifications. NPTL is now inside GNU Libc on Linux and is (or at least tries very … Read more
I decided to write a slightly more detailed explanation. The “magic” here lies in the operating system. Both programs do start up at roughly the same time, and run at the same time (the operating system assigns them slices of time on the processor to run) as every other simultaneously running process on your computer … Read more
You need to add the dynamic library equivalent of -L: -Wl,-rpath-link,/path/to/lib This will cause the linker to look for shared libraries in non-standard places, but only for the purpose of verifying the link is correct. If you want the program to find the library at that location at run-time, then there’s a similar option to … Read more
iptables will list packet and byte counters if you specify option -v for verbose, e.g. iptables -vL. Likewise iptables-save will list all entries including the mentioned counters for each chain, but not for each table entry (on some systems iptables-save requires option -c to include counters).
You either add /usr/local/lib and/or /usr/local/lib64 to $LD_LIBRARY_PATH, or add them to /etc/ld.so.conf, or (since you already have /usr/lib64/libgmp.so.3) add a missing symbolic link: cd /usr/lib64 sudo ln -s libgmp.so.3 libgmp.so (and perhaps the same for /usr/lib). Note that /usr/lib64/libgmp.so.3 might be a different version from /usr/local/lib64/libgmp.so, make sure ghc can actually be used with … Read more
Instead of using the predefined [:cntrl:] set, which as you observed includes \n and \r, just list (in octal) the control characters you want to get rid of: $ tr -d ‘\000-\011\013\014\016-\037’ < file.txt > newfile.txt
This blog here points out how to fix this problem. http://www.mikestechblog.com/joomla/operating-systems-section/operating-systems-ubuntu/155-500-oops-vsftpd-refusing-to-run-with-writable-root-inside-chroot.html The issue being that the user’s root directory is writable. The Frontier Group provides you with a fix on vsFTPd. Here are the steps to be taken (copy paste from the tutorial, in case the link dies) login as root (or sudo..) and do … Read more
