We are moving to an office with a server closet that may not have sufficient depth to have a standard server rack. I found a vertical rack mount online (that mounts to the wall) that is 4U. Are there negative effects to mounting servers vertically instead of horizontally?
I have a Sonciwall NSA 3500 and I'm setting up the SSL VPN according to this guide.
I get through setting up the Sonicwall router, but then to test it says "Users can now go to the public IP of the sonicwall. Notice the new “click here for SSL login” hyper link". However, when I go to the public ip of the Sonicwall I don't get a web page, it just times out. Is there some other setting that I'm missing in order to make the SSL VPN login page public?
I'm running Apache 2.2 on a linux box. Is there any reliable way of detecting if a visitor to my website is connecting from a VPN? I've heard of attempting to open a tcp connection on the remote ip address, which can sometimes identify the user as using a proxy. But could the same method work with VPN users?
I like using grep but sometimes I just want to search for the names of files in a directory tree, but don't want grep to open the files and search inside them. Can grep do this?
