How can I determing the IP address of a server, when I use ping and then the ftp:// address I get the response unknown host.
I'm just trying to get the IP for a ftp install. When I use the browser or Gftp I conect with no problem but I can't determin the IP for a ftp install.
You can try (you may need to do this as root):
dig -a the.host.name
If it can be found, then this will tell you the IP address, as in:
# dig -a dns1.btinternet.com
; <<>> DiG 2.2 <<>> -a dns1.btinternet.com ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6 ;; flags: qr rd ra; Ques: 1, Ans: 1, Auth: 4, Addit: 4 ;; QUESTIONS: ;; dns1.btinternet.com, type = A, class = IN
;; ANSWERS: dns1.btinternet.com. 35182 A 194.73.73.172
If this too fails, then you should look to your /etc/resolv.conf file, which should include the IP address of at least one reachable DNS server, on the lines of
nameserver 194.73.73.94
as well as a suitable "search" line.
Hoping this helps, Ted.
dig is interesting and confusing at the same time check this out I'm not sure if Suse redirects or what. I cann't see how two sites could have the same IP address. Sorry that I didn't cut some of this but I wasn't sure as to what is important. papa@linux:~> dig ftp://ftp.gwdg.de/pub/linux/suse/ ; <<>> DiG 9.2.3 <<>> ftp://ftp.gwdg.de/pub/linux/suse/ ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 36365 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;ftp://ftp.gwdg.de/pub/linux/suse/.
