I ban my server from getting to my other VPS
Hi everyone, every time I tried to login (or use scp) into my server
I got this error message
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
Apparently this message due me whitelist IPs that can login my server log time ago, but I could not find how that happened...
I checked /etc/hosts.deny file and nothing there
and this VPS log:-
sshd[124]: Connection closed by authenticating user root 1.2.1.1 port 99998 [preauth]
I suspect this is mostly iptables issue
iptables -L INPUT -v
# Warning: iptables-legacy tables present, use iptables-legacy to see them
I can't see current rules guess due to (iptables being upgraded) and not displaying legacy rules?

I don't think a "permission denied" has something to do with iptables.
PAM & crap perhaps?
"Permission denied" means:
if you suspect it's from your hosts.deny file then if it's available i would try to use VNC on whatever vps provider your with. other then that your kinda screwed
Permission denied means it's not iptables but rather the ssh daemon.
You're getting rejected at the front door. This is the software not letting you in. This isn't iptables. You can still get on the road to get to the front door. IPTables would have prevented you from turning on the street to get to the front door.
its public key I added to log in automatically from my laptop to that VPS, but I thought I could still use user login from other device
Alright I solve it by enabling password login in sshd_config file
PasswordAuthentication yes
