Hi folks, Ubuntu-6.06.1-LAMP-server-amd64 On installing ddclient, what shall I fill in on; Interface used for dynamic DNS service: TIA B.R. satimis
Hi falko, I found it. "eth0" Now I have ddclient installed. $ sudo /usr/sbin/ddclient -daemon 300 -syslog No printout. Where can I find the start/stop/restart scripts. Besides how to test ddclient to check whether it works. TIA B.R. satimis
They are in /etc/init.d. Check the log files. Also, you can stop your internet connection and connect again and check if the IP address of your domain has been updated.
Hi falko, Tks for your advice. $ dpkg -l | grep ddclient Code: ii ddclient 3.6.2-6ubuntu1 Update dynamic IP address at DynDNS.org ddclient is running. IP address was updated on DYNDNS.ORG server whenever this server reconnected. I have it confirmed on login DYNDNS.ORG website. But failed to ping my domain. $ sudo ping -c 3 satimis.homelinux.com Code: PING satimis.homelinux.com (58.152.161.53) 56(84) bytes of data. --- satimis.homelinux.com ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2001ms iptables has been stopped. Please advise how fix this problem. B.R. satimis
Hi falko, I don't have router nor hardware firewall. The server is directly connected to an ADSL modem with a CAT5 cable. The another end of the ADSL modem is connected to a telephone wall socket with a telephone cable. The ADSL modem is supplied by ISP and does not need any setup. B.R. satimis
So you use your server for surfing the web? Or how do you use your internet connection with multiple systems?
Hi falko, No. Once this server has been full configured and running properly. I'll connect a workstation to this server. Internet surfing will be done on workstation. Sorry, I don't follow. Whether you meant how to make broadband connection to the workstation. I'll add another NIC on the server to do masqerading. B.R. satimis

Hi falko, I did it before without breakthrough. Now I tried again; # sudo /etc/init.d/firewall stop Code: Removing all iptables rules: [End of flush] # ping -c 3 satimis.homelinux.com Code: PING satimis.homelinux.com (58.152.181.13) 56(84) bytes of data. (it hung here. Waiting for input???) On presing [Ctrl]+c it prompted; Code: --- satimis.homelinux.com ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 1999ms # ping -c 3 219.78.151.64 Code: PING 219.78.151.64 (219.78.151.64) 56(84) bytes of data. 64 bytes from 219.78.151.64: icmp_seq=1 ttl=64 time=0.064 ms 64 bytes from 219.78.151.64: icmp_seq=2 ttl=64 time=0.051 ms 64 bytes from 219.78.151.64: icmp_seq=3 ttl=64 time=0.049 ms --- 219.78.151.64 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2001ms rtt min/avg/max/mdev = 0.049/0.054/0.064/0.010 ms "219.78.151.64" is IP address on connection. My server is not always up, only switched on during testing. On next connection another IP address will be asigned. It won't change until turning off the server. Tks B.R. satimis
You're pinging the wrong IP address because satimis.homelinux.com points to the wrong IP address. It is possible that 58.152.181.13 is unused at the moment, therefore your pings don't work. You should make ddclient update the IP address (currently 219.78.151.64).
Hi falko, Further to my late posting. I requested a friend to make following tests on his WinXP box C:\>ping -n 3 satimis.homelinux.com Code: Pinging satimis.homelinux.com [58.152.181.13] with 32 bytes of data: Request timed out. Request timed out. Request timed out. C:\>telnet satimis.homelinux.com 25 Code: Connecting To satimis.homelinux.com...Could not open connection to the host, on port 25.

Hi falko, I discovered the trick. $ sudo ping -c 3 www.satimis.homelinux.com Code: PING satimis.homelinux.com (58.152.183.105) 56(84) bytes of data. 64 bytes from n058152183105.netvigator.com (58.152.183.105): icmp_seq=1 ttl=27 time=35.9 ms 64 bytes from n058152183105.netvigator.com (58.152.183.105): icmp_seq=2 ttl=27 time=36.3 ms 64 bytes from n058152183105.netvigator.com (58.152.183.105): icmp_seq=3 ttl=27 time=35.0 ms --- satimis.homelinux.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2401ms rtt min/avg/max/mdev = 35.045/35.761/36.313/0.573 ms Then it worked. It needs www as prefix. Please advise what other tests I have to continue. TIA B.R. satimis
Hi falko, "satimis.homelinux.com" may have problem. On browser running "satimis.homelinux.com"/"www.satimis.homelinux.com" can't display the homepage. I have registered another free domain "satimis.freeddns.com" $ sudo ping -c 3 satimis.freeddns.com Code: Password: PING satimis.freeddns.com (220.246.238.244) 56(84) bytes of data. 64 bytes from n220246238244.netvigator.com (220.246.238.244): icmp_seq=1 ttl=64 time=0.033 ms 64 bytes from n220246238244.netvigator.com (220.246.238.244): icmp_seq=2 ttl=64 time=0.033 ms 64 bytes from n220246238244.netvigator.com (220.246.238.244): icmp_seq=3 ttl=64 time=0.034 ms --- satimis.freeddns.com ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2015ms rtt min/avg/max/mdev = 0.033/0.033/0.034/0.004 ms On browser running "satimis.freeddns.com" displayed the homepage.

Please read my previous posting again. satimis.freeddns.com is working because it is pointing to the correct IP address (your server 220.246.238.244), but satimis.homelinux.com is pointing to the wrong IP address (58.152.183.105).
Hi falko, "58.152.183.105" is the IP address asigned by dyndns.com/org at time of registration. Each time ping "satimis.homelinux.com" it automatically pointed to this IP. It is completely out of my control. Logon their site my running IP address found updated, same as on "ifconfig". I sent dyndns.com a mail informing them this matter without a reply. I'm now working on "satimis.freeddns.com". My friend on his WinXP can browse the homepage on my server with; "satimis.freeddns.com:8080" port 80 seems blocked by ISP. On WinXP box :- C:\>telnet satimis.freeddns.com Code: Connecting To satimis.freeddns.com...Could not open connection to the host, on port 23. No connection could be made because the target machine actively refused it. C:\>telnet satimis.freeddns.com 25 Code: Connecting To satimis.freeddns.com...Could not open connection to the host, on port 25. A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

must go in one line in your main.cf. Please change it and restart Postfix. What are the outputs of Code: netstat -tap and Code: postfix check then?
