• Graphing per-user CPU usage on a Linux machine

  - by mart1n

  I want to graph (graphical output would be great, i.e. a .png file) the following situation: I have users A, B, and C. I limit their resources so that when all users run a CPU intensive task at the same time, those processes will use 25%, 25%, and 50% of CPU. I know I can get the real-time stats using top but have no idea what to do with them. I've searched through the huge top man page but haven't found much on the subject of outputting data that can be graphed. Ideally, the graph would show a span of maybe 30 seconds. Any ideas how to achieve this?

• Add users in Windows machine without AD

  - by guillem

  I have several development machines where I am the administrator. We are using AD in my organization but is maintained by and offshore IT group any request takes a long time. We are currently granting access to developers on development machines manually so it's a bit annoying to maintain although at least it's fast. We have also a lot of external consultants that need to use those machines for some time. Is there any tool or method to maintain a set of users synced on those machines without the need add them to an AD group?

• Direct access to website's database with single click?

  - by Mick

  I have noticed that when selecting options (drop down menus, radio buttons etc) on some websites you see an ever more complex URL being created and then you can use that URL to access that website at a later date and go straight to the page with your desired options. Unfortunately on other websites the URL remains fixed and you appear to have no choice but to select the options all over again. I was wondering if there was some utility that would help automate this process.

• Iptables to lock down compromised server to a single ip

  - by ollybee

  I have a Linux server which is compromised, I can see nasty looking perl scripts executing with root privileges. I want to get some data off it before I wipe it. How can I block all inbound and outbound traffic except for my ip? It's a Centos server I assume i can do this with iptables? I'm aware a the server is rooted there is a possibility that attackers could have made changes on the server that would prevent this from working. Ill be testing to make sure and only have the server online for a couple of hours before it is nuked.

• KVM Switch for a mac and a Windows (XP or 7) machine to share VDU

  - by Adrian Parker

  Have a MacPro (snow leopard) connected to an (windows standard) Asus 25" monitor via a DVI--VGA adapter. Now the boss wants me to work from home, so I want to share my Asus display with a Windows XP laptop. No doubt once my wife sees this, she will want to do the same thing, but with a Windows 7 laptop. So what I would like, I think, is your recommendations for a KVM switch (or better solution) that allows the Mac and a (windows 7 or windows xp) laptop to share the Asus display. Bonus marks if they can share Apple keyboard and magic mouse, but am quite happy to use separate mouse keyboards. The MacPro is the one that is always connected, the laptops come and go. Any ideas? Thanks in advance for any help.

• WD Elements Desktop External - Not recognised on a single computer

  - by Aelexe

  My WD Elements Desktop External is no longer recognised on my main computer. It has worked fine in the past, but now all of a sudden is not detected. It does not prompt when plugged in, nor does it show up in the disc management interface or the device manager. It appears to be aware that it is plugged in however as the light on the external blinks rapidly for a short while after being plugged in. The strangest thing however is that it works fine on other computers, including my family computers and my laptop. I have attempted to troubleshoot the issue by trying various USB devices in multiple ports on each system to see if there is any correlation with the issue, but have come up with nothing that gives me an idea of what is going on. I have also attempted to format the external using my laptop, but that has not helped either. If anyone has had a similar issue, or knows of any potential solutions, please post your advice. Thanks for your time.

• Cannot SSH into Virtual Machine

  - by MasterGberry

  I am running a CentOS VM on my desktop that I use for development testing when coding in python. At my school I have a dedicated IP setup for the VM and my desktop so I never seem to have an issue ssh'ing from desktop into VM. I am now at home for winter break and cannot seem to SSH into the VM using the local ip address behind my router, the external IP with port 22 forwarded to my VM, or anything. Strangely enough I can ssh into my production server and then fromt here ssh into the VM, but not from my desktop to the VM directly What should I do to get this to work? Thanks

• Send email from different domains to different external IP's on a single server

  - by user140429

  I have set up a windows 2008 R2 server to route email from Exchange 2010 using SMTP Server in IIS. I have 3 seperate domains and would like to route each one through a different internal and external IP for (IP Reputation etc), at the minute it is only using the primary IP on the server to route email externally. Is this at all possible using SMTP Server in IIS, or is there any other software available to do this?

• pscp: how to copy a file from a windows machine to a non-home location on another windows machine?

  - by help

  I want to copy a file from C:\temp on MachineA to C:\final on MachineB. I tried to use the following command, but it gave me an error (permission denied): C:\PROGRA~1\putty\pscp.exe -i C:\PROGRA~1\cwRsync\home\rcadmin\.ssh\id_rsa_private.ppk [email protected]:C:\final\test.txt C:\temp\test.txt It turned out I can only access C:\users\direcpc in my source computer. So if I put the file in C:\users\direcpc\text.txt, then it would work: C:\PROGRA~1\putty\pscp.exe -i C:\PROGRA~1\cwRsync\home\rcadmin\.ssh\id_rsa_private.ppk [email protected]:/test.txt C:\temp\test.txt But I want to access any location on my source computer instead of just my user home directory, is there a way to do this?

• Single email Stuck in Backend Exchange Queue

  - by Kyle Brandt

  I have an outgoing message that has and is stuck in a queue on my backend mail server. The queue is: Internet Mail SMTP Connector (MY_FRONT_END_SERVER_NAME)-524350ff... It is in state retry with 183 failures. It is only one message and all other mail is flowing. The message is not particularly large. My limited understanding, a guess really, is that this message should get handed off to the front end mail server and sent to the remote hosts for which it is destined, so it should even matter if the remote host is up. However, I can telnet to the smtp provider of that host. How can I find out why it is stuck in this queue, and can I force it out somehow (unfreeze doesn't help me)?

• Turning a (dual boot) Ubuntu 9 into a virtual machine

  - by xain

  I have a dual boot box (Ubuntu 9 and Vista) and I'm about to upgrade Vista to Win 7. Being Ubuntu my main development environment, I'd like to use it as it is from the new environment via VirtualBox or VMWare. I know tools like clonezilla that backup entire drives; in my case, the linux partitions are distributed between several disks which in turn contain both linux and windows data. My intention is to use some backup tool (like Clonezilla if it fits) that allows me to ONLY backup the linux partitions distributed in several disks. Any hints ? Thanks in advance.

• How to single click and select text?

  - by jasondavis

  I am having a issue I have never experienced until recently, I believe (hoping) it is just a setting I can change? The issue: When I left click and hold the left mouse button down and slide the mouse around to select text in a document or webpage, it works as far as selecting the text, however when I release the left button , it does not stop selecting more text. Instead I must hit the left button again to stop it from selecting more text. This is very annoying, at first I thought I just had a faulty mouse but I just bought a new mouse and it is the same problem. I am running windows 7 pro Please help, hoping it is something simple I overlooked?

• cannot connect to my nginx server from remote machine

  - by margincall

  I thought that it's iptables problem.. but it seems not. I really have no idea about this situation. I'm getting a server hosting(CentOS). I installed Nginx + Django and nginx uses 8080 port. A domain is connected to the server. When I executed "wget [domain]:8080/[app name]/" in the server, it worked. Of course, "wget 127.0.0.1:8080/[app name]/" has no problem. (wget [server ip]:8080/[app name]/, either) However, from other computers, connecting was failed. (message says, no route) I checked my firewall setting. I excuted these commands. iptables -I INPUT -p tcp --dport 8080 -j ACCEPT iptables -I OUTPUT -p tcp --sport 8080 -j ACCEPT iptables -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT /etc/init.d/iptables restart I don't really understand all options of commands and I think there were useless commands, but I just tried all googled iptables settings. But still I cannot connect to my server. What should I check, first? I don't know this is important, but add to this post. On 80 port, an apache server is running. It works fine, I can connect to apache from other computers. There is DB connecting issue, (PHP to MySQL) but I think that it is just PHP coding bug. please excuse my low-level English. I'm not native English speaker.. but I tried to explane well as far as possible. Thank you for reading this question.

• IIS and Apache on the same machine?

  - by MLS

  I have a Windows 2003 Server running IIS (due to an ASP Site needing to be hosted). I wanted to add some non ASP sites (HTML, PHP and MySQL) so I was thinking I could just run apache on 8080. What confuses me a bit is if someone hits DomiainA.com, IIS intercepts it and forwards it to DomainA.com:8080 where apache is running. I could do this by putting a server side javascript re-direct in the IIS www-root for the domain. What else can I do that might be more proper?

• Multiple PCs - Single profile

  - by martixy

  Or how to create an AD(or similar) environment at home? So... I work in this big IT company(they have and AD environment ofc) and I've seen first hand how nice integration and log-in-from-anywhere(roaming?) profiles can be. So I wanna create the same setup at home, where I have 3 machines. Mostly logging in with the same profile and preserving the settings(things like UAC being off, a few group policies I've customized, things like that). How can I achieve something like this?
