I'm suspicious that the switchport isn't up - what does "show interface fa0/1 switchport" say? With the exception of DTP (dynamic trunking protocol), trunking is unidrectional, which is to say one side of the trunk doesn't necessarily need to agree with the other side.

I have come across this exact scenario several times before, after spending an hour plus checking my server's firewall. So I hope this will be a reminder to myself and others to check other ...
A virtual host definition by itself doesn't create any HTTP ports. It is only used to specify which applications accept HTTP requests received via which HTTP ports (this includes HTTP ports local to the application server and HTTP ports on a Web server in front of the application server). To actually listen on a given port, you have the following options: ...
I received the same message when trying to use the ls command to list the files stored on a UNIX FTP host server from my Ubuntu command line.
