#StackBounty: #ubuntu #debian #kvm-virtualization #telnet #proxmox Can't telnet a server from vps

Bounty: 50

i try to understand why i can’t telnet this server 213.132.48.107 from any of my VPSs.
Well this ip is for a mail server i don’t own but our emails are not received by this server. when i checked the log i saw this error:

554 5.7.1 You are not allowed to connect.
Connection closed by foreign host.

I thought i’m in black list so i tried to telnet to that server from all my VPSs (7 VPSs) and always get the same error.

telnet 213.132.48.107 25
Trying 213.132.48.107...
Connected to 213.132.48.107.
Escape character is '^]'.
554 5.7.1 You are not allowed to connect.

But when i try from a dedicate server i can telnet.

I have contacted the server admin but didn’t get any response. I still don’t see any reason for them to block my IP address. we just installed the server and it’s used for regular emails only.

Please help me

My VPSs run debian/ubuntu/centos and all created created by proxmox

#StackBounty: #linux #bash #debian #shell #dash Trap on DEBUG signal for the dash shell?

Bounty: 50

With the bash shell, you can install a trap on the synthetic DEBUG signal. This is useful and will execute your function or bit of code on every shell command. For example:

$ trap 'logger -t shell "${BASH_COMMAND}"' DEBUG

Looking at the dash shell source code, I seem to understand there’s no such DEBUG signal available.

Are these any workarounds or alternatives to achieve the same result with the dash shell?
