The first thing to do in this situation is to use the -v option to ssh, so you can see what types of authentication is tried and what the result is. Does that help enlighten the situation? In your update to your question, you mention “on another local Ubuntu”. Have you copied over the ssh … Read more

cat /proc/<pid>/environ If you want to have pid(s) of a given running executable you can, among a number of other possibilities, use pidof: AlberT$ pidof sshd 30690 6512 EDIT: I totally quote Dennis Williamson and Teddy comments to achieve a more readable output. My solution is the following: tr ‘\0’ ‘\n’ < /proc/<pid>/environ
Dig will also do it quite nicely: dig -t txt example.com and if you add the +short option you get just the txt record in quote marks with no other cruft.
Many people seem to be afraid of mixing stable with testing, but frankly, testing is fairly stable in its own right, and with proper preferences and solution checking, you can avoid the “stability drift” that puts your core packages on the unstable path. “Testing is fairly stable??”, you ask. Yes. In order for a package … Read more
There isn’t a great deal of difference between the two; 127/8 (eg: 127.0.0.0 => 127.255.255.255) are all bound to the loopback interface. The reason why is documented in the Debian manual in Ch. 5 Network Setup – 5.1.1. The hostname resolution. Ultimately, it is a bug workaround; the original report is 316099.

The github page has all the information. reptyr – A tool for “re-ptying” programs. reptyr is a utility for taking an existing running program and attaching it to a new terminal. Started a long-running process over ssh, but have to leave and don’t want to interrupt … Read more
First of all a minor terminology nitpick: chmod doesn’t remove permissions. It CHANGES them. Now the meat of the issue — The mode 777 means “Anyone can read, write or execute this file” – You have given permission for anyone to do (effectively) whatever the heck they want. Now, why is this bad? You’ve just … Read more
You can check if a process listens on a TCP or UDP port with netstat -tuplen. To check whether some ports are accessible from the outside (this is probably what you want) you can use a port scanner like Nmap from another system. Running Nmap on the same host you want to check is quite … Read more
