Link: Prepare Your Pi To Send Mail Through Gmail

Suppose you have set up your Raspberry Pi to do some stand alone work. It would be nice if it could email you occasionally, for instance if there’s something wrong. Or it may send you status updates on the work it’s doing. For this you could use the SMTP server of your ISP. However, if your Pi isn’t stationary and roams around on multiple networks, this is not an ideal situation. If you connect your Pi to a different network, operated by a different ISP, chances are that you can’t send any messages.
A better solution would be to use a Gmail account for that. In this description I presume you already have a Gmail account. If not, you can get one for free at www.gmail.com. You may also decide to create a new one for your Raspberry Pi. The same account can even be shared among multiple Raspberry Pies. Rumour has it though that Gmail will only allow 100 mails sent per account per day. So if you share your account among too many machines you may start hitting the ceiling soon.

Link: Tutorial on “chkconfig” Command in Linux with Examples

Whenever a new service (like Samba or NFS) is added to a Linux system, it is not configured to start automatically when the system starts up. So, by default, whenever you add a new service, you’ll have to start it manually after the system reboots. ‘chkconfig’ command allows you to configure that newly added service to start after every system start up automatically. Not only this, you can change the configuration so as to add any service at different run-levels. With ‘chkconfig’ you can display the list of services those are configured for startup at a particular run-level.

Link: 3 Easy Ways to Send Emails From the Command Line in Linux

While working with the command line, there are times when you might want to manually send an email to communicate one-liner information, say a complex command or an important note to yourself or a friend. Normally, that requires you to open a web browser, log in to your email account, frame an email containing the required information, and then send it.

That’s too long of a process for a small thing, isn’t it? What if you could do that from the command line itself? Yes, it is possible, and we’ve already discussed a couple of ways to do that in Linux. In this article, we will discuss three more ways to send email from the command line in Linux.

Link: U-Boot and Linux Source Code for ODROID-C1 Board Has Been Released

Hardkernel ODROID-C1 board, a more powerful $35 alternative to the Raspberry Pi, garnered a lot of attention when it was announced last week. At the time source code was not available, but as scheduled, U-boot and Linux source code is now available, and the full Android SDL should be released on February 2015. Instructions to get the code, and build both Linux and U-boot are available on ODROID-C1 Wiki, and I’ve just given a try to Linux instructions myself to see if I would encounter any issues in Ubuntu 14.04.

Link: How to block unwanted IP addresses on Linux efficiently

You may want to block IP addresses on your Linux box under various circumstances. For example, as an end user you may want to protect yourself from known spyware or tracker IP addresses. Or when you are running P2P software, you may want to filter out connections from networks associated with anti-P2P activity. If you are a sysadmin, you may want to ban access from spam IP addresses to your production mail server. Or you may wish to block web server access from certain countries for some reason. In many cases, however, your IP address block list can grow quickly to tens of thousands of IP addresses or IP address blocks. How can you deal with it?
