Debian is a powerful operating system, especially when it comes to web servers. It is well-known for its robustness and reliability, with few issues. But sometimes, even in incredibly well-maintained Linux systems, an issue can occur. Recently, I encountered one such issue and decided to write about how I fixed it here for the benefit of anyone else encountering this same issue in the future.
The issue that I was facing was that a specific application was not connecting properly with the web server. After spending a bit of time researching and trying various troubleshooting steps, I finally decided to try and locate the man page for the application. Man pages are helpful if you want to know about the available options for a certain command.
Usage: man [OPTIONS] …
man displays the manual pages of the specified PAGENAMES. The
manual is searched for in the system’s manual hierarchy.
-i, –ignore-case ignore case distinctions when searching
-k, –apropos search for string in clickable index entries
-f, –whatis search for strings in short descriptions
-w, –location print the location of the man page files
-h, –help display this help and exit
After finding the man page, I was able to get the information I needed to troubleshoot the issue. I learned that the application had an option to change the port it was connecting through, which was exactly what I was looking for. By changing the port, the application was able to connect to the web server successfully.
In conclusion, if you’re ever stuck and need to know more about a command you can try looking up its man page. Just type in
man [command here] and it should help you out. It’s an incredibly useful resource when trying to troubleshoot an issue.
