I'm looking for a tool that can be installed on our monitoring server and which allows us to perform scheduled requests to our web sites in order to keep them from shutting down (asp.net). I don't want to use a web service since we already have a dedicated monitoring server. Our monitoring software doesn't really have the ability to do ...
My initial installation for the MySQL had no password for root. I assigned a password for root and everything worked fine. Due to some reason (don't ask why) I had to revert back to the original settings where root didn't have any password. I changed the root password to '' (empty string). The problem now is that MySQL doesn't run with ...

I've seen this asked a lot around on the internet, with no satisfactory answers or root cause. Sometimes it's just 'well, replace your RAID controller', or 're-run grub install', etc. I'm running into this issue on a substantially large amount of hosts as to convince me there's some non-hardware reason it's happening - but it's also no...

I need to use sendmail from Macs in an office. At the moment, I can get it to work on the two development Macs (which I think is due to MAMP being installed and working), but getting it to go on the others seems to be a problem... I assume it's down to some config issue, and hope there's someway to fix it (without resorting to installin...
I have a linux dev server I watch, and lately its chugging at some points so I'd like to keep a better eye on it. I used to use Gkrellm, but its been a pain to try get Gkrellm to build on my Mac. Besides servering X remotely (which would not be optimal), I guess i'm looking for alternatives to Gkrellm. I would like a program that will...
