#strace — Public Fediverse posts

`lnav` is a fab tool for analysing logs. Today I used it for debugging a verbose `strace -f` log file to analyse what the problem was w/smth and it was cool

Tip: hit `<tab>` to edit, enable, and disable existing text filters added w/e.g. `:filter-in` and `:filter-out`.

New scenario released! 🚀

Having the config file for a program is not enough. You also need to put it in the right place so that the program can find it. But it's not that easy when you don't know where the program is looking for its config file!

Happy fixing!

用 strace 換掉 syscall

Brought to you by #strace-ing sssd to the connect(), getrandom(), and few read()/write() calls before switching to #GnuTLS localization files to get the “error message”, where it became obvious no actual certificates were being checked locally… Then checking #sssd's source code, diving into the #openldap rabbit hole and its dedicated config file, ending with:

# TLS certificates (needed for GnuTLS)
TLS_CACERT /etc/ssl/certs/ca-certificates.crt

Updated the article: Monitor file access by Linux processes

Linux is powerful with the help of small utilities like lsof and strace. They help with monitoring disk and file activity, of new and running processes. #linux #lsof #ltrace #strace #syscall

Feedback and boosts welcome 🤟

I will admit, I reach for #strace quickly, like I reach for #procmon on Windows. Same root cause (other than me being impatient).
