Just built my homemade server rack and I have 6 newly acquired 'used servers' and an old and very heavy monitor with keyboard.
How can I best hook up the monitor/keyboard to multiple servers and just switch them? Is there such a thing a 'switch' for peripherals?
I would need plenty of connection cables not doubt.
What does everyone use to monitor their servers? I've come across a pretty impressive service from Panopta but haven't head of them before. Has anyone tried them out?

I searched but I haven't found anything. I need a server/client software to monitor all my Linux VPS/Servers. Do you know anything easy to use and install. I want to have a main server that verifys all the others.

I just got a Dell 1600SC dual xeon 2.8 from the Planet with a Dell DRAC3 remote access card. In my RHEL3 system this hardware combination works great, but in the new RedHat Enterprise Linux 5 system the DRAC accepts no keyboard input after RHEL5 loads, thus making it impossible to login to the OS through the drac remote console redirect. Tech support suggested it was because the RedHat Enterprise 5 and CentOS5 kernel does not load the PS/2 keyboard driver which is required for the Drac3 to accept keyboard input. (a drac4 works, but that's not an option for this server I would guess.)
At tech support's suggestion, I added
atkbd.set=2
to the /boot/grub/grub.conf file
rebooting had no change - still text input to enter the bios, but no text input to login to the OS.
I also added
serial --unit=0 --speed=9600 -word=8 --parity=no --stop=1
terminal --timeout=2 serial console
which I saw in /etc/grub.conf (which is not linked to /boot/grub/grub.conf but instead a separate file) but still no luck - no keyboard input accepted through the drac3 remote console to login to the os through the drac console redirect.
Has anyone solved this hardware/software combination? Or is RHEL5 simply not going to be backwards compatible with the Dell DRAC3 hardware?
Any ideas, suggestions, or solutions would be greatly appreciated as I've been working on getting a solution for this for a week now and no closer at this point.
I would really like to have the DRAC as a backup connection with my server incase any firewall or software update issue ever prevents me from connecting via ssh. I hate to have roll back to an older OS though to get it. I'm stuck.
I have a lot of questions here so if you can't answer them all I understand. even pointing me somewhere where I could get the answers would be appreciated; hardware sites focusing on server hardware, forums focusing on such, etc.
we plan to have three different types of servers:
- db server (self explanatory. mysql. for forums, mysql driven sites.)
- file server (lots of files around ~2-10MB, consistant 70mbps right now, but we want more room for upgrades. needs a LOT of storage room.)
- web server (lots of php files, but also static things like plain html, images, etc. also includes all misc services for the setup-- dns, etc.)
could I be given a rundown for which hardware each of the three should have? I don't need specifics, even just knowing that more ram is important here while cpu doesn't matter as much, or that the fastest disks available are a must, etc would all be valuable info for me. despite that, I certainly wouldn't mind specific hypothetical hardware configs.
for the database server I'm assuming the more ram the better. not entirely sure about the cpu? also not positive on disks...
for the fileserver, how much ram would be practical or useful? disk io will be an issue I'm because plenty of people will be pulling files at once so the disk needs to read from multiple places. scsi (and even raptors) are not an option as we need 750GB+ of space on a reasonable budget. more ram will take some load of of the disks, but how much is neccessary / reasonable?
for the web server I'm assuming cpu first, then ram, but it'll likely need less ram than the db server?
I'm more lost on the disks than anything. scsi on the fileserver is not an option under any circumstances due to $/GB. for the db & web server I'm willing to pay for scsi if the performance increase really does warrant the extra money, but I'd like to be convinced before shelling it out. if you have benchmarks geared at server hardware when it comes to disks I'd really appreciate it.
also, what's the best way to network these together when colocated? each one with a dual gigabit ethernet port and then the communications go to and from the router?
if you use a site monitoring service (or two) do you need to setup monitors for each website/domain on your VPS or can you just monitor the primary services on the VPS?
Pluses/Minuses for either way?

I have a 20U rack space and i use 4U of this space (1U + 2U servers and a 1U switch).
There is a 20Mbit internet connection on a 100Mbit network.
But here comes my problem, some friends have there servers in my rack space to, There is 12 servers that are my friends and i want to know how much traffic they use.
I want to know how many GB traffic they use to i can charge them (they don't pay right now).
2 of my friends servers must max take 50gb traffic!
Is there a switch that can do theys two things?
Show traffic and limit traffic?

I just setup my own LAMP server.
It is only used for my own domains so I want to be able to watch all mail that gets sent from my server, via php or otherwise.
Basically I just want to be able to personally monitor what mail is getting sent from my server so that I can watch for possible spammer activity.
I am using postfix and webmin.. I have sendmail installed to, but I don't think it is getting used..
I guess theres got to be a log somwhere... but I am not sure where it is?
I have postfix set to CC me of all mail that gets sent but, it doesnt seem to work all the time.. just for certain things..
We have a few customers who have multiple C classes with us and we are wondering how most of you monitor for blacklisting.
We currently randomly pick a few IPS and check them once a month but this is not very thorough. We were wondering if there is a program out there that can check say a /20 automatically once a month or atleast something we can initiate an automated check once a month with?
I am wondering what services it is best to monitor with Nagios which I've installed on my Centos 5.3 VPS. I wish to monitor and understand all essential services of the VPS itself at this stage but, generally, to make the best possible use of Nagios as an analytical tool as well as basic monitoring notifications, etc.
I already have a rough idea based on the main services being run. But I imagine there may be more to this than meets the eye, in particular, in view of any potential performance cost, etc.
I am especially keen to obtain as detailed a picture as possible concerning performance related criteria with a mind to indicating possible improvements that could be made.

View 1 Replies View Relatedwe've got our new machine up and running smoothly. It's a core2duo running CentOS with Plesk 8.3. We have 2 drives in a RAID 1 configuration for reliability sake, and I'm looking for something to help me monitor the status of the disks in the array. Since RAID is pretty useless unless you know if one of the disks has died.
Is there some open source utility that will monitor this and email me if something is wrong? Perhaps something with a nice web interface?
Even better... is there some addon to plesk that will help with this?
Since upgrading to Apache 2 I am no longer able to tell which domains are the busiest using CPU/Memory/MySQL Usage. Now Apache processes are all lumped together and individual domains only show cron, mail and FTP usage. I opened a ticket with cPanel and they know of the problem but there is still no solution. Is there another way I can tell which of my sites is using the most resources until this bug is fixed?
