Hi again, sorry for the delay. I actually tried to disable ufw, but everytime I restarted the server it was enabled again, even thou I actually used the disable function. However, now does it suddenly work, maybe me disabling it and the system reactivating it again modified the rules somehow...

well, when I was saving, it just said error on line 8, it didn't specify anything... regarding the list, I was afraid you wanted to see it, i have never ever seen a stranger list, and I have no idea what half of it means, but here we go: *nat :PREROUTING ACCEPT [144:39368] :INPUT ACCEPT...

yep, I got that one installed, but something about the line -A FORWARD -o enp0s3 -j ACCEPT is wrong, at least what it says when I'm trying to save it.. but running sudo iptables -A FORWARD -o enp0s3 -j ACCEPT in the terminal works... no idea why?

yes, will iptables-save > /etc/iptables/rules.v4 save the information above? .. nope, it didn't..

after a lot of trial and errors, it suddenly worked. But as a newbie, I'm not sure if all this is necessary, and how do I get it to stick? sudo iptables -t nat -A POSTROUTING -o enp0s3 -j MASQUERADE sudo iptables -A FORWARD -o enp0s3 -j ACCEPT sudo sysctl -w net.ipv4.ip_forward=1 sudo iptables...

I've actually solved this one, it was an error in a script, (the one you just solved for me), that caused cron to send an email, which failed, and when I saw the error message was about a mail, and not the "messer" script. I faulty assumed that it was complaining about a previous cron function...

You got it completely right, it worked, thx a lot! Not so concerned about security since this is a computer only I have physical access to..

hi all! I've been trying to get a .sh script to work the past days but I'm obviously not smart enough to grasp the concept, because it doesn't work. the script is suppose to send a message via messenger, and the program messer the "solution" but something isn't right, because it says Logging...

I've been encountered a strange phenomena. I've been messing with Cron, so it runs a script called startup.sh, which it does. First I wrote the script to send an email, but later I rewrote it to send a message instead. However, when restarting the server, nothing happened. Then I checked the...

I'm accessing the Linux view vnc by phone, so all ways to shorten commands are good. But, now I listed the directory, and it is an executable file, I'm updating the original question with a screenshot.

There are actually no way to delete a post, so everyone, ignore this, I'm not sure the file is a program anyway..

I copied a program that had spaces and stuff that made it difficult to write in the terminal. I simply copied it to pss (sudo cp [appname] [pss]) But when I write pss in the terminal, it says that There is something called pss in that directory now..

Not anyone that recognize this issue? Maybe there is something missing that I need to install, since this is a minimal setup?

I've just installed Ubuntu 18.04.3 LTS mini (to use as a server) But when I'm trying to create a new gpg/gpg2 key it just stops after I've confirmed my passphrase.. nothing happens after that. It don't freeze, I can stop it with ctrl-c This one was running for an hour before I stopped it. Any...
