So I have a few old dell computers. I want to use them to set up a ubuntu linux server in my basement. Is there a way for me to set up the server over all the pcs so that I can use the processing power of them all together for the server. What would be the best way for me to set a server up with these machines.
View 2 RepliesI'm looking at setting up a couple automated systems: Here are a few examples:
* Internal accounting system to download and process emails
* Public web server to visit
I could put each system on its own separate box -- for example, it's generally good practice to separate anything that external users have access to (such as a webserver) from internal processes such as accounting. Now, rather than dishing out the money for two separate servers, could I get away with just installing new instances of VMWare on the same box for each system?
To give you an idea, these are not large scale computationally sensitive systems. The accounting one is simply downloading and tallying emails, and the latter is just a webserver with maybe 5 hits per day on a good day. I could definitely pick up a new box for say $50, but I wanted to know the general practice of using VMWare on the same box versus two separate boxes.

View 1 Replies View RelatedI've got a machine running Ubuntu Server that is on several VLANs. Each VLAN has its own subnet and the server has an address on each subnet. The switches are set to allow tagged traffic to the server for each VLAN that it is on. Switch ports ending with workstations are given untagged ports on whatever VLAN is appropriate. Workstations are given addresses on a subnet for each VLAN via DHCP. All this works great and hosts on any subnet/VLAN can access the server as normal via its address on that subnet/VLAN.
Accessing the machine by its address on a non-local subnet is where I run into a problem. Inter-subnet traffic has to go through a router, which has been set up appropriately. Running tcpdump on the server and pinging it from a workstation on a subnet, using its address on a different subnet, shows the server receives the ping, but sends no response:
Code:
sudo tcpdump -i vlan4 -n
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

In my production setup, i have 3 servers using the same mount point. However, i see that the IOPS is low. Does this kind of architecture have any impact on IOPS. In case it is neutral, how can i tune my setup for better IOPS.
View 1 Replies View RelatedI have an issue with users logging into a server. There are multiple (5 or so) database admins that have to log into a windows 2003 server and from there log into a red hat server. Once they are in the rhel box they execute an app (let's say xclock) that gives them an xwindows session on their desktop. Currently only one person can do this at a time, but they have asked me to configure it to allow multiple users to log into the red hat box from the windows server and run an xwindow.

View 8 Replies View RelatedI'm curious how I can use a Windows client with two separate accounts to connect, at the same time, to a SMB server hosting two shares. (Provided permissions and accounts are all in order)
Scenario:User1 is always logged onto a Windows client mapped to a Public share on a Linux SMB server.I need a way to keep User1 connected to the Public share and then when needed, allow User1 to provide User2's credentials to connect to a Restricted share.The only way I've been able to do this is to disconnect from the Public Share then reconnect to the Restricted share using User2's credentials. (This is the issue because I need to keep User1 connected to the Public share).Is this a limitation of SMB? Or am I missing a configuration? Please point me in the right direction
create an Apache web server with multiple user accounts, for work. Each user needs to be able to upload his/her files via SSH Each user needs his/her own web directory, (preferably in their home directory for ease with permissions) There web directories need to be password protected Only one user account (mine) should be allowed remote SSH control. It needs to be easy to add new users to the system.

View 3 Replies View RelatedRecently I've been earning money doing web development, php, html/css, MySQL and so on. What I have encountered a lot are clients that need a complete solution. They need their site built, but they also need a hosting solution. I've sent more than just a few clients off to GoDaddy, and quite frankly, I'd like to cash in on some of that.
It would do wonders for my business if I could offer them a hosting solution with full support on top of building their site. My problem is I have no idea how to do this. So I'd like to know how I can host multiple sites on the same server. Does anyone know of a nice guide I can follow to set this up? It's really important that I can add sites fairly easily over the internet. Since I will be away at school, I won't have direct access to the server

i'm trying to set up password-less SSH login between multiple instances on my server. My goal is to be able to monitor all instances, whether I created them or not, with Zenoss.
Current setup: 3 machines
A: Zenoss host- owned by me, Access via putty with my keypair
B: instance- owned by me, access via putty with my keypair
C: instance- owned by teammate, access via putty with their keypair
I'm able to set up password-less SSH login between the instances I have created (A to B), however, I cannot between my Zenoss monitoring instance and any instances not created by me(A to C). Whenever I try to copy the id_rsa.pub file to these instances, I keep getting a Permission denied(public key) error. I believe the problem is that I have log in to my instances using my keypair but must use the the other instances creator's keypair to access their instances.
My company has 2 locations. I have a server running BIND, Apache, and MySQL. I'm setting up a second server just in case the primary goes down. I'm sure it's bad form to it the way I'm doing it, but how might I go about configuing my backup? Should I do it as a Secondary DNS server?

The problem is that if I have two separate TXT records, only the first one gets returned when doing a dns query on it.

View 1 Replies View RelatedI find FTP server software confusing in Linux. Using ServU for Windows for an example, all I need to do is to create users via the ServU interface and choose a folder I want that user to have access to and their permissions, and viola, they can connect to that directory, and that directory only.
But in the the land of Linux, it apparently can't be managed this easy. I have a web server with multiple domains, and therefore multiple users need access to their own web root. So with that in mind, what FTP server software should I use (there are plenty out there) and how would I go about to create a user per domain, so that they can log in using FTP to manage their site, and only have access to their own web root, and nothing else?

If all deamons are running then script should print short output: "License server is running" if one of this daemons is not running, output should "License server is not running". Is it possible to write small loop to check it ? Let say, loop will take new daemon name from deamons pool and will check if its running.

Maybe somebody could help me with this loop that in the future I could also use; daemonD, daemonE, daemonF.etc.etc. if all daemons from pool is running then..."Software is running"
