Services like LastPass are extremely popular for automatically entering credentials (username and password combinations) for logging into Web sites. They also generate passwords as needed and store them. They're not without their problems, however.
The two major issue with these types of services are the following:
One would assume that printer sharing can be set up in Ubuntu 13.10 (Saucy Salamander) by following the Network Printing with Ubuntu community wiki page in the Ubuntu documentation. I found, however, that the set-up for the print server, the machine that actually shares a printer, didn't actually work. I kept running into a "client-error-forbidden" message while trying to set up a client machine on the network.
I worked on a project lately where I needed access to a Windows file server. There are two (2) ways of doing this, as a regular user (available only to the person setting it up), and as root (the system administrator). Setting up the connection system-wide using the latter approach will allow read-only access by everyone on the system, but they won't be able to write to it.
I have a client who uses a Cisco VPN to protect their network, and I exclusively use Ubuntu in my consulting work. At the moment, they don't easily work together out-of-the-box, even though they should. To get access to their network, I was provided with a PCF file, used to configure VPN client software to connect to the VPN server. However, after importing the configuration file, I simply couldn't connect.
Tired of printing a PDF, signing it and then scanning it back in as a PDF? Besides needing to use a printer/scanner twice, this also turns your entire signed PDF into an image, losing all of the textual information. This makes it impossible to do text searches on it later.
Here is a recipe to maintain that information and save some work for your printer/scanner.
Drupal requires an SMTP client to send mail. You could install a full-featured mail transfer agent (MTA) like Postfix on your (virtual) machine to serve this function, but it's overkill if you only need to send mail through PHP. Instead, install msmtp. It's lightweight and much simpler to configure.
