If you have one of the larger builds of dd-wrt then you probably have PPTP support built into the firmware. This will allow you to move VPN connections to the router instead of having to connect from each desktop which will securely make the remote network seem like part of the local network.
If you are in process of downgrading your iPhone or iPod Touch you will more than likely be downloading the older firmware directly from apple.com. When you download this firmware it is provided as a zip file with a .zip file ending such as iPhone2,1_3.1_7C144_Restore.zip. If you unpack this file it will include a couple directories and numerous files as listed below.
A friend contacted me the other day because he was having an issue starting his development environment which consists of Ruby, PostgreSQL, and Mongrel. Ruby communicates with PostgreSQL using the postgres-pr gem version 0.6.1. Starting things using “ruby script/server” from within his Ruby project had been working for months without issue and there had been no confguration changes to Ruby, Postgres, or Mongrel so it appeared to not be configuration related. After getting a brief explanation of the issue I logged into his laptop and attempted to start the server. Below is the error received when attempting to start the server using “ruby script/server” via a terminal window on the Macbook Pro.
Using whois can be a valuable tool to find out more information about a domain via the command line in Linux. A typical whois query can be performed to find out where the domain was purchased and using it again with the -h (host switch) can provide more detailed information about the domain. Using the -h switch will typically provide information such as who purchased the domain, when the domain was purchased, when the domain expires, etc. Below are a couple basic examples of how whois can be used followed by whois queries with the output.
My Dell d420 came with a biometric fingerprint scanner which is configured using the Wave Systems Embassy Security Center. If you have recently reinstalled the OS on your laptop more than likely the operating system configuration is out of sync with the TPM(Trusted Platform Module) Security Chip. This means that the biometric security will work preboot however it will not work for Windows logon. So you will not be able to swipe your fingerprint and automatically logon to Windows securely and you will also not be able to lock your computer and log back into Windows by swiping your fingerprint.
