Hello, I haven't used SSH from Putty for awhile now and I must have changed something which is now preventing me from accessing my home server.
sshd_config
Code:
# Package generated configuration file
# See the sshd_config(5) manpage for details
# What ports, IPs and protocols we listen for
Port 49452
# Use these options to restrict which interfaces/protocols sshd will bind to
#ListenAddress ::
#ListenAddress 0.0.0.0
Protocol 2
# HostKeys for protocol version 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
#Privilege Separation is turned on for security
UsePrivilegeSeparation yes
# Lifetime and size of ephemeral version 1 server key
KeyRegenerationInterval 3600

# Logging

# Authentication:

PermitRootLogin no
StrictModes yes
RSAAuthentication yes
PubkeyAuthentication yes
#AuthorizedKeysFile %h/.ssh/authorized_keys
# Don't read the user's ~/.rhosts and ~/.shosts files
IgnoreRhosts yes
# For this to work you will also need host keys in /etc/ssh_known_hosts
RhostsRSAAuthentication no
# similar for protocol version 2
HostbasedAuthentication no
# Uncomment if you don't trust ~/.ssh/known_hosts for RhostsRSAAuthentication
#IgnoreUserKnownHosts yes
# To enable empty passwords, change to yes (NOT RECOMMENDED)
PermitEmptyPasswords no
# Change to yes to enable challenge-response passwords (beware issues with
# some PAM modules and threads)
ChallengeResponseAuthentication no
# Change to no to disable tunnelled clear text passwords
PasswordAuthentication yes
# Kerberos options
#KerberosAuthentication no

#UseLogin no
#MaxStartups 10:30:60

AcceptEnv LANG LC_*
Subsystem sftp /usr/lib/openssh/sftp-server
# Set this to 'yes' to enable PAM authentication, account processing,
# and session processing. If this is enabled, PAM authentication will
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication. Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
# the setting of "PermitRootLogin without-password".
# If you just want the PAM account and session checks to run without
# PAM authentication, then enable this but set PasswordAuthentication
# and ChallengeResponseAuthentication to 'no'.
UsePAM yes
I tried updating my iptables, but I'm not too sure exactly what I'm doing there.
Code:
rhys@tomato:~$ sudo iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT tcp -- anywhere anywhere tcp dpt:49452
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Code:
rhys@tomato:~$ sudo iptables-save > firewall.rules
rhys@tomato:~$ nano firewall.rules
# Generated by iptables-save v1.4.12 on Thu Jan 9 12:37:21 2014
*filter
:INPUT ACCEPT [94093:49078855]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [103366:116841892]
-A INPUT -p tcp -m tcp --dport 49452 -j ACCEPT
COMMIT
# Completed on Thu Jan 9 12:37:21 2014
I have port 49452 on both the public and lan forwarded to my tomato server. And I'm accessing SSH via my routers public IP on 49452.
I'm guessing I've enable the firewall which is blocking access, although running sudo ufw disable doesn't do anything. It just returns Firewall stopped and disabled on system startup.
Can anyone help?
