Flushing iptables broke my pipe, how can I save my instance?
- by Niels
I was setting up my iptables when I performed a iptables -F and my ssh pipe broke.
This is the last output of my session:
root@alfapaints:~# iptables -L
Chain INPUT (policy DROP)
target prot opt source destination
ACCEPT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere state NEW,ESTABLISHED tcp dpt:2222

root@alfapaints:~# iptables -F
Write failed: Broken pipe
I tested my connection just before and I was able to connect with ssh.
Now I did a nmap scan and not a single port is open anymore.
I know my VPS is running on VMWare ESXi, could a reboot help?
Or if not could I attach and mount the disk to another vm to save the data?
Does anybody have some advise?
And maybe an explanation what happend or what could have cause my pipe to break?
ps: I didn't save my rules on the config directories of iptables.
But used a file I stored in ~/rules.config to apply my rules like this: iptables-restore < rules.config
So probably a reboot would help?
Thanks a lot in advance.
