Botched TCP wrapper remotely; how can I connect? Haste is needed!
I am trying to help a colleague connect locally to a linux machine (I believe Debian), which uses TCP wrapper for security.
I ssh'd onto the computer and tried to give him access by clearing the contents of /etc/hosts.allow, but failed to make any changes to /etc/hosts.deny.
As a result, I can no longer ssh onto it, but get this error:
ssh_exchange_identification: read: Connection reset by peer
So... now we're both locked out. How can I access this computer? Or how can I instruct him to access it?
Thanks. Unfortunately, there were some lines in hosts.deny, but I didn't clear them.
It seems that I'll not be able to connect remotely, but what are my options for a local connection? How can I (instruct my colleague to) connect if the TCP wrapper is blocking?
Couple of options:
1. (preferred) Boot the host into rescue mode from the boot menu.
2. Create a live USB of Debian/Ubuntu, etc. Boot from it, mount the root (/) partition of the host.
