[Solved] Cant Telnet My Box

1

I don’t get it. I wanted to use a cool script to automatically make a snapshot from droplets on digitalocean. But it seems, that I can’t enter the command the right way, so that the email is actually send. I always get an error about a service not known and a socket error:

Sorry, I think it is easy, but I can’t figure it out. I tried the whole day… Thanks for you patience!

Please follow the instructions at https://mailinabox.email/maintenance.html and then report back.

Okay, I followed the instructions. All is green except for 2 domains where I can’t set the DNSSEC DS records cause the provider doesn’t offer that.

Now I wanted to use do_snapshot to make automatic backups of my droplets on digitalocean. That works fine (the backup is completed), but always in the end, when it should sent an email, I get the error messages I posted above.

The command I type in: do_snapshot -p 2 --only 6269613 -k 3 -c -m to:TO from:FROM -t address:HOST user_name:LOGIN password:PASSWORD port:587 -v

I also tried with authentication and enable_starttls_auto.

When I type telnet -d box.mydomain.com

I get the following back:

Trying 2a03:b0c0:3:d0::2a:3001... setsockopt (SO_DEBUG): Permission denied

Hope that helps. And thanks for your help!

I just telnet to my box.domainname.tld

telnet -d box.domainname.tld 587

I believe you must supply the port.

HTH
