Hi falko, Previously I ran "satimis.homelinux.com" as domain registered with dyndns.org # /etc/ddclient.conf Code: daemon=600 pid=/var/run/ddclient.pid use=web, web=checkip.dyndns.org/, web-skip='IP Address' login=(login) password=(password) protocol=dyndns2 server=members.dyndns.org wildcard=YES #use=if, if=eth0 #satimis.homelinux.com example.dyndns.org custom=yes, example.com Each time IP address of the server changed the IP address on dyndns.com website also changed. (remark: IP address only changed on connection) Now I'm running "satimis.freeddns.com" as domain registered with "http://www.changeip.com/". Please advise how to change "ddclienc.conf". TIA B.R. satimis
Any errors in your mail log when you try to send emails? It must be Code: netstat -tap , not Code: netstat - tap This part looks wrong in your ddclient.conf, because normally all entries are like Code: parameter=value
An ADSL router itself normally blocks ping requests. You need to "open" this post on your ADSL router.

I was thinking you had Postfix installed all the time... Any errors in your mail log? What's the output of Code: postfix check ? Do you have ISPConfig installed?
Hi falko, Yes, except at the time I installed "sendmail". postfix was removed automatically because Ubuntu only allows one MTA. After testing I removed "sendmail" and reinstall "postfix".

My ISP adds "nd" infront of "smtp.netvigator.com" made me suffered wating lot of time. satimis.homelinux.com registered with dyndns.org/com also works without problem. It concludes my test on dynamic IP. Tks. My next test will be on static IP. I'm now negotiating a plan with my ISP and I'm prepared to register a domain for further test. Tks again. B.R. satimis
