Analyze Network Access

From http://www.lug-erding.de/artikel/nts.html:

telnet <IP|Domain> 80
<ENTER>
HEAD / HTTP/1.0
<ENTER>
Host: <Domain>
<ENTER>

If

Trying <IP>

then name resolution works and if

Connected to <IP|Domain>

then TCP is fine and errors are located in higher layers. If

Connection refused

then probably no one listening at port or firewall otherwise see answer.

ping -c <NumberOfPings> -s <Size>

If size is e.g. 4000 pakets have to fragmented which could give hints for the error.

traceroute -n <IP> // Linux
tracert <IP> // Windows

DNS problems could be checked

nslookup <Domain>

Reboot

sudo reboot

Shutdown

sudo shutdown -h 0

Update

sudo apt-get update

Error corrected according to here
