Hi, sorry for all of the questions that i have... I just changed the ip address in /etc/hosts and since i did, ssh stopped working it says that the connection timed out, but i changed it back and still cannot connect, where should i start to troubleshoot?
Okay, i attached my current /etc/hosts file. As far as logs... I'm looking in the web1/log/error.log and not seeing anything. When i try to ssh in it times out, and yes i have restarted ssh. Thanks for all of your help.
SSH does not log to a local apache error logfile.Plesae have a look in the syslog, messages log or auth.log in the directory /var/log/
Okay, two of the logs showed up stuff, auth.log had nothing: Code: messages log Aug 27 22:25:47 ubuntuserver kernel: [170597.552184] Inbound IN=eth0 OUT= MAC=00:03:47:8b:82:37:00:1a:c4:69:d5:29:08:00 SRC=[B]MYIPADDRESS[/B] DST=[B]MYSERVERSIPADDRESS[/B] LEN=48 TOS=0x00 PREC=0x00 TTL=56 ID=10198 DF PROTO=TCP SPT=49205 DPT=22 WINDOW=65535 RES=0x00 SYN URGP=0 syslog Aug 27 22:24:28 ubuntuserver kernel: [170518.611539] Inbound IN=eth0 OUT= MAC=00:03:47:8b:82:37:00:1a:c4:69:d5:29:08:00 SRC=[B]MYIPADDRESS[/B] DST=[B]MYSERVERSIPADDRESS[/B] LEN=333 TOS=0x00 PREC=0x00 TTL=255 ID=61626 DF PROTO=UDP SPT=67 DPT=68 LEN=313 auth.log nothing Exactly what I get in my terminal window is: Code: ssh [b]MYSERVERSIPADDRESS[/b] -l administrator ssh: connect to host [b]MYSERVERSIPADDRESS[/b] port 22: Operation timed out
Okay, iptables -l shows: Code: Chain INPUT (policy DROP) target prot opt source destination ACCEPT tcp -- home anywhere tcp flags:!FIN,SYN,RST,ACK/SYN ACCEPT udp -- home anywhere ACCEPT 0 -- anywhere anywhere ACCEPT icmp -- anywhere anywhere limit: avg 10/sec burst 5 DROP 0 -- anywhere 255.255.255.255 DROP 0 -- anywhere adsl-76-243-116-255.dsl.wlfrct.sbcglobal.net DROP 0 -- BASE-ADDRESS.MCAST.NET/8 anywhere DROP 0 -- anywhere BASE-ADDRESS.MCAST.NET/8 DROP 0 -- 255.255.255.255 anywhere DROP 0 -- anywhere 0.0.0.0 DROP 0 -- anywhere anywhere state INVALID LSI 0 -f anywhere anywhere limit: avg 10/min burst 5 INBOUND 0 -- anywhere anywhere LOG_FILTER 0 -- anywhere anywhere LOG 0 -- anywhere anywhere LOG level info prefix `Unknown Input' Chain FORWARD (policy DROP) target prot opt source destination ACCEPT icmp -- anywhere anywhere limit: avg 10/sec burst 5 LOG_FILTER 0 -- anywhere anywhere LOG 0 -- anywhere anywhere LOG level info prefix `Unknown Forward' Chain OUTPUT (policy DROP) target prot opt source destination ACCEPT tcp -- ubuntuserver home tcp dpt:domain ACCEPT udp -- ubuntuserver home udp dpt:domain ACCEPT 0 -- anywhere anywhere DROP 0 -- BASE-ADDRESS.MCAST.NET/8 anywhere DROP 0 -- anywhere BASE-ADDRESS.MCAST.NET/8 DROP 0 -- 255.255.255.255 anywhere DROP 0 -- anywhere 0.0.0.0 DROP 0 -- anywhere anywhere state INVALID OUTBOUND 0 -- anywhere anywhere LOG_FILTER 0 -- anywhere anywhere LOG 0 -- anywhere anywhere LOG level info prefix `Unknown Output' Chain INBOUND (1 references) target prot opt source destination ACCEPT tcp -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT udp -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp dpt:5900 ACCEPT udp -- anywhere anywhere udp dpt:5900 ACCEPT tcp -- anywhere anywhere tcp dpt:3389 ACCEPT udp -- anywhere anywhere udp dpt:3389 ACCEPT tcp -- anywhere anywhere tcp dpt:smtp ACCEPT udp -- anywhere anywhere udp dpt:25 ACCEPT tcp -- anywhere anywhere tcp dpt:bootps ACCEPT udp -- anywhere anywhere udp dpt:bootps ACCEPT tcp -- anywhere anywhere tcp dpt:mysql ACCEPT udp -- anywhere anywhere udp dpt:mysql ACCEPT tcp -- anywhere anywhere tcp dpts:www:81 ACCEPT udp -- anywhere anywhere udp dpts:www:81 LSI 0 -- anywhere anywhere Chain LOG_FILTER (5 references) target prot opt source destination Chain LSI (2 references) target prot opt source destination LOG_FILTER 0 -- anywhere anywhere LOG tcp -- anywhere anywhere tcp flags:FIN,SYN,RST,ACK/SYN limit: avg 1/sec burst 5 LOG level info prefix `Inbound ' DROP tcp -- anywhere anywhere tcp flags:FIN,SYN,RST,ACK/SYN LOG tcp -- anywhere anywhere tcp flags:FIN,SYN,RST,ACK/RST limit: avg 1/sec burst 5 LOG level info prefix `Inbound ' DROP tcp -- anywhere anywhere tcp flags:FIN,SYN,RST,ACK/RST LOG icmp -- anywhere anywhere icmp echo-request limit: avg 1/sec burst 5 LOG level info prefix `Inbound ' DROP icmp -- anywhere anywhere icmp echo-request LOG 0 -- anywhere anywhere limit: avg 5/sec burst 5 LOG level info prefix `Inbound ' DROP 0 -- anywhere anywhere Chain LSO (1 references) target prot opt source destination LOG_FILTER 0 -- anywhere anywhere LOG 0 -- anywhere anywhere limit: avg 5/sec burst 5 LOG level info prefix `Outbound ' REJECT 0 -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTBOUND (1 references) target prot opt source destination ACCEPT icmp -- anywhere anywhere ACCEPT tcp -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT udp -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT 0 -- anywhere 10.0.1.37 ACCEPT tcp -- anywhere anywhere tcp dpt:www ACCEPT udp -- anywhere anywhere udp dpt:www ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT udp -- anywhere anywhere udp dpt:https ACCEPT tcp -- anywhere anywhere tcp dpt:smtp ACCEPT udp -- anywhere anywhere udp dpt:25 ACCEPT tcp -- anywhere anywhere tcp dpt:ssh ACCEPT udp -- anywhere anywhere udp dpt:ssh ACCEPT tcp -- anywhere anywhere tcp dpts:ftp-data:ftp ACCEPT udp -- anywhere anywhere udp dpts:20:fsp ACCEPT tcp -- anywhere anywhere tcp dpt:81 ACCEPT udp -- anywhere anywhere udp dpt:81 LSO 0 -- anywhere anywhere and netstat -tap shows the following: Code: (Not all processes could be identified, non-owned process info will not be shown, you would have to be root to see it all.)

I just noticed that I cannot ping my servers ip address, I can however get through to the website and I can also ping my webservers router, not sure if this has anything to do with it, but anything that may help.

I also reset my router totally (which is also my firewall) in case it was a fiewall setting, but that did nothing. Any more ideas?
Are you trying to connect locally, or from a system outside your LAN? If the latter, ask your ISP if they are blocking certain ports such as SSH...
The only thing that i am confused about is that this all worked before, would they of started blocking it just recently? I thought it was right around the time that I changed my etc/hosts file. Plus I cannot connect locally because it is a static ip and my router doesn't allow local addresses when you have a static ip. UPDATE: I just called them and asked if they blocked it and they said no.
I suppose i could re-install my os. If i do, where can i find all of the mail and such so that i won't lose it. Thanks.
If you're using mbox, all mailboxes are in /var/spool/mail. If you're using Maildir, there's a Maildir for each user in his homedir.
