![]() ![]() Rohit shook hands with me and told me that it seems he isn't needed anymore. ![]() I leaped in joy and punched the air with my signature style. Then came the moment of truth, as me and Rohit stood there waiting for some form of output to appear on the screen while the cursor kept blinking, when the welcome sound of the message-received tone on Rohit's handset sounded. So I insert my SIM into the device, and I try to send a message to Rohit's cell phone by typing the following into the console, $: gsmsendsms -d /dev/ttyS0 XXXXXXXXXX “testing” With apt-get install gsm-utils, I got the binaries installed in a jiffy and a quick browse through the man pages gave me all the info I needed to use this tool. My immediate aim was to just test the modem and a quick look up on google told me that there's this thing called gsm-utils, which is a package used to send SMSes using a GSM modem (duh?) in linux. And since I was new to the whole idea of AT commands then, I didn't know how to talk with the serial port in linux, which is done using minicom, by the way. No Windows! Now this dude had never used Linux before and even went to the extent of typing AT on my linux terminal. But since we ITR folk at MNIT kick ass, we don't use Windows see? All our servers run on Debian, Gentoo, FreeBSD, Deeproot etc. He was supposed to show me how to use the AT commands and all that. Rohit, the technician who the Genus people (the company which provided us the modem) had sent over to demonstrate the modem, only knew how to operate it via hyper terminal which is an interface for Windows by which you can communicate with your serial port. So this is where we choose to deploy Zabbix with a GSM modem on my netmon machine. In such a situation, the solution would be to use a media which doesn't involve the local area network or the internet for that matter, one of them being, SMSes. We may use email or a messaging client like Jabber, but in the event that something goes wrong with the core switch or the gateway, and the internet and/or the intranet is out, this will be useless. One important thing as far as network monitoring solutions for a CWN is concerned, involves setting up a system by which the administrators are informed in case one of our services goes down. ![]()
