Hi, I have an strange issue with bind9 which I can't solve. I have defined my own and local domain, domain.local. In the forward resolution file I have the following entries: domain.local. IN A 172.17.70.1 www IN CNAME domain.local. nslookup resolves domain.local and...

Thanks for the links. I'll read them carefully. Best regards!

Thanks a million, @osprey.

Hi! I have seen many ways to manage services in Ubuntu. Such as Systemctl - sysctl - systemd - /etc/init.d scripts and so on. Some of them seem to work always, whereas some not. ¿What is the difference among them all? Thanks!

Hi. Thanks for the explanation. I tend to use only one tool to avoid conflicts. I have seen however that some configuration is temporary and others are persistent. Depending on the tool you use. ¿What is the major difference between Network Manager and systemd-networkd? Thanks again!

Hi! I'm struggling to configure a quite simple network using Debian. I can't see the difference between using the following commands to set the networking parameters. ip ifconfig netplan /etc/network/interfaces file When to use one or another? Why so many tools for the same purpose? Does any...

Understood. Thanks!

I think I have it clearer now. I guess if I have to analyze an unknown server, it's better to take a look both at /etc/cron* and also to crontab for all users. Am I correct? Thanks!

Hi. I have been working with crontab to schedule jobs. I usually run crontab -l (to list the jobs) or crontab -e (to edit them). Always bearing in mind each user. I also have found the following directories: /etc/anacrontab /etc/cron.d /etc/cron.daily /etc/cron.hourly /etc/cron.monthly...

Found the error. The certificate was issued to a domain. Hence the access by IP gave that warning. Thanks!

Hi! Thanks for the reply. I have added the corresponding files to the directives: SSLEngine on SSLCertificateChainFile /etc/letsencrypt/live/domain.com/fullchain.pem SSLCertificateKeyFile /etc/letsencrypt/live/domain.com/privkey.pem SSLCertificateFile...

Hi! I have used CERTBOT and successfully get the SSL certificates. However, I don't understand the purpose and difference between these 2 files: /etc/letsencrypt/live/domain.com/fullchain.pem /etc/letsencrypt/live/domain.com/privkey.pem What does each one do? Thanks!

Haha! Will do. I just was fed up and wanted to get rid of the problem. Thanks!

Yes. Default is 6, altthough the line was commented (??). I'm using Ubuntu 22.04.

OK. I have set: PasswordAuthentication yes I still was getting the message Too many authentication failures I uncommented and set the directive: MaxAuthTries 1000 So I got rid of the message, was prompted for the password and now able to add the pubkey. Thanks!

OK. Here's what I do: LOCAL: /home/localuser/.ssh/ssh-keygen (keypair named "test2") /home/localuser/.ssh/ssh-copy-id -i test2.pub [email protected] (test user already exists in 192.168.1.138) /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "test.pub" /usr/bin/ssh-copy-id...

But what if I want to add a key other than root?

Hi! The user I'm issuing the command with only exists in my local machine. So I'm not prompted for any user/pwd. ssh-copy-id -i /home/user/.ssh/test.pub [email protected] and I get /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already...

Hi! I have been using SSH for a long time, and I do know the purpose of ssh-copy-id command. If I copy the pubfile contents and paste it into the authorised_keys file on the target server, that's OK, because I already have access to the target server, and there are not security concerns...

Sure. Thanks a million for your help!
