Hi guys, Hehe.. I thought I want to share this. In previous email, I said about monitoring server room. I just realize that we have this quite old sms server appliance in the room. It's still running though. I want to setup cronjob from linux machines, to send mail to that sms server, and it will then send sms to my cell about the machine condition. Problem is, nobody knows how to configure the sms server, and there's no docs beside a little description in the web UI. Been googling around few hours, but since it's quite old and proprietary, no good result.

Problem is, the sms server's qmail refuses to work if I use hostname in the mail like mycellnum@sms-server. If I want to use mycellnum@192.168.1.100, sendmail refuses to send it as "host not found". So, out of curiosity, I define this in this /etc/hosts: 192.168.1.100 192.168.1.100 And now sending from sendmail to mycellnum@192.168.1.100 works!

is it a feature or what? In network convention, all-numeric hostname is not allowed right? Hehe.. anyway, now I can monitor my server room using sms.
