[CentOS] Suggestion for Server Room monitoring
Hi all, I have a situation like this: Our little server room is always on. It has an air conditioning unit, but barely enough. So sometimes during weekend, the temperature could reach unhealthy level, like 29 degree Celsius. Currently, there's no personnel to monitor it 24 hours a day. I'm thinking of using a tool to monitor the temperature, and then send sms/email when it reaches certain threshold. Anyone has an idea? Could be software based or hardware one. Thank you. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

That would have been what I suspected also that the disk would show up just as any other disk. Very odd. Perhaps I'll just wait for 5.3 unless there is another suggestion. Side note: I have an amd 6200+ and now an Amd Quad 940. There is significant improvement in the 940. Project compile went from 12 seconds down to 9. Copying 12GIG file went from 8 minutes down to 5. So now I'm waiting on 5.3 to see if ext4 helps that even more! Any day I hope. let me know if there are other things to try for the esata. Have a great evening.

No, NTLM auth works in Firefox (at least on Firefox on Windows, I don't think it will work in other platforms though). I tested configuring Firefox on Windows to do NTLM auth, and it worked with the IIS sites my company had. As I said before, unfortunately I couldn't get Apache on Linux to work with NTLM authentication.

[CentOS] network driver at installation time
Is there anyway to load a network driver at installation time. Centos 5.2 x86_64. Alternatively, is there a way to do a USB network driver at boot? Either is fine...

Could be software based or hardware one. > Thank you. If you've got an APC UPS, there's a chance you can get a temperature sensor that attaches to it. That can be checked from Nagios, which can send alerts when thresholds are reached. You can also graph temperature over time (via SNMP) using Cacti, so that you can verify that Nagios is doing the right thing. Note that even if you use lm_sensors rather than an external temperature sensor[1], it's still a good idea to use Nagios and/or Cacti in conjunction with it. I believe Nagios has a check_lmsensors plugin available. ;) -I [1] - lm_sensors reports internal temperature, which is usually much higher than external temperature. So tune your thresholds accordingly... ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] funny SMS server tips
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 mycell...@sms-server. If I want to use mycell...@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 mycell...@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. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
