• Mac Excel 2011: find Items in one column that are not in another column

  - by robert-jakobson

  Hi this is a repeat of the question: Excel: Find Items in one column that are not in another column I have two columns in excel, and I want to find (preferably highlight) the items that are in column B, but not in column A. What's the quickest way to do this? However, the answer given below to in the above-menitoned thread no longer applies to Mac Excel 2011. E.g. there is no "name-a-range" option available on right click etc.. Therefore I am asking this again. Select the list in column A Right-Click and select Name a Range... Enter "ColumnToSearch" Click cell C1 Enter this formula: =MATCH(B1,ColumnToSearch,0) Drag the formula down for all items in B If the formula fails to find a match, it will be marked #N/A, otherwise it will be a number. If you'd like it to be TRUE for match and FALSE for no match, use this formula instead: =IF(ISNA(MATCH(B1,ColumnToSearch,0)),FALSE,TRUE) How should this answer be restated to apply to Mac Excel 2011?

• SharePoint Server 2007 and HTML Forms - How to control access rights

  - by Anarkie

  I'm working with Hosted SharePoint 2007 with Forms Server. I need to allow client access to submit HTML forms designed in Infopath. Problem is, I need to make sure the clients don't see the library. There is sensitive data that will be on these forms. I also need to have a repeated library that is based on the Internal Admin records and requirements. Outside of making a seperate library per customer, does anyone have any suggestions? My Goal: 1: Customers enter their requests through a link or provided page 2: Internally address the requests and perform required arrangements, add billing and payment fields 3: Have SharePoint metrics, reports, etc... based on the provided intormation and status. Thanks in Advance!!

• How to extend a window on 4 virtual desktops on Windows 7

  - by Patrice

  This site is very cool, and i often get many answers in it :) But today, I've a question for you. My Problem is: - I want to use a virtual desktop or resolution expander for windows 7 - I want to multiply per 2 a window resolution (i.e. seeing only 25% of one window on a screen) I tried simple tricks that didn't work for me, and installed a virtual desktop (Dexspot, a great one), but I can't manage to strech a window (Google chrome) over the 4 desktops simultaneously. Do you understand my problem, and have an answer to it? This would be great help ;-) See ya! Patrice

• Xmodmap configuration

  - by Krishna S

  On my Debian Linux machine Ctrl+Alt+F1 is bound to a virtual terminal. I can see the corresponding entry by running xmodmap -pke keycode 67 = F1 XF86_Switch_VT_1 F1 XF86_Switch_VT_1 Per this thread, which I might add is consistent with what I've read elsewhere, the columns on the right hand side of = correspond to key, Shift+key, AltGr+key and Shift+AltGr+key. Given that, I don't understand how the keycode mapping for F1 (above) works for Ctrl+Alt+F1. It seems it should really be either Shift+F1 or Shift+AltGr+F1? Here's the output of xmodmap -pm on my machine: shift Shift_L (0x32), Shift_R (0x3e) lock Caps_Lock (0x25) control Control_L (0x42), Control_R (0x69) mod1 Alt_L (0x40), Alt_R (0x6c), Meta_L (0xcd) mod2 Num_Lock (0x4d) mod3 mod4 Super_L (0x85), Super_R (0x86), Super_L (0xce), Hyper_L (0xcf) mod5 ISO_Level3_Shift (0x5c), Mode_switch (0xcb) Can anybody explain it?

• how limit the number of open TCP streams from same IP to a local port?

  - by JMW

  Hi, i would like to limit the number of concurrent open TCP streams from the the same IP to the server's (local) port. Let's say 4 concurrent conncetions. How can this be done with ip tables? the closest thing, that i've found was: In Apache, is there a way to limit the number of new connections per second/hour/day? iptables -A INPUT -p tcp --dport 80 -i eth0 -m state --state NEW -m recent --set iptables -A INPUT -p tcp --dport 80 -i eth0 -m state --state NEW -m recent --update --seconds 86400 --hitcount 100 -j REJECT But this limitation just messures the number of new connections over the time. This might be good for controlling HTTP traffic. But this is not a good solution for me, since my TCP streams usually have a lifetime between 5 minutes and 2 hours. thanks a lot in advance for any reply :)

• What are the cheap CDN for Origin Pull?

  - by DucDigital

  I've read several thread around ServerFault about this, but still I am not satisfy with the answer so I post a question here. I need a Origin Pull CDN that support big file (more than 200MB). I don't need a storage place since they are too small, just to relay the server. Also the price should be afforable, ofcourse not more than 150$ a month for their smallest plan. I also need to pay by credit card since I do not work or stays in the US so it's hard for me to do a bank wire. Thank you very much

• Throttling apache downloads selectively

  - by Synchro

  I have a linux box running Debian Sarge (old I know) and apache 2.0.54. It serves two kinds of files - regular web pages and small images, and a lot of large podcast mp3s. The podcast downloads swamp the connection and make the rest of the site unresponsive, so I'm looking to throttle the data transfer rate (not the request rate) of just the podcasts. I've set up haproxy using this technique which does what it says it will, but solves a different problem - even only 5 simultaneous podcast downloads is enough to saturate the link. In a perfect world, haproxy would support per-connection throttling, but it doesn't. So far I've looked at mod_bw (won't compile for me, seems unsupported), mod_cband (unsupported, widely reported as problematic) and iptables using tc. The iptables approach would allow me to throttle things, but would not be at all selective, slowing down everything on the server, not just the podcasts, so would just move the bottleneck without changing overall behaviour. Ideas?

• Adaptec 2020SA RAID controller Set up in RAID5, one drive went down, can I still get data?

  - by SJaguar13

  I have 6 1tb drives in a RAID5. 1 drive went down. On the RAID was 2 virtual machines that I really need back up and running. The spare drive I have to put in the server is a 1.5tb drive, which exceeds the physical per drive limit of the 2020SA. The drive is found in the disk utility, but it is not found in the array management section. I cannot add the drive to the array to have it rebuild. I have a replacement drive along with some spares on their way from Newegg, but I am still looking at a few days of downtime. Is it possible to use the 5 working drives to get the VMs copied off and on to another server or do I just have to wait for the drives to get here?

• Recommended SMTP Relay Service [closed]

  - by Ryan

  I've got a legacy application that needs an smtp server to relay emails. Each client has various control over their IT infrastructures (from little to none at all), so I can't necessarily install an smtp server on each of their machines. Can anyone recommend a basic SMTP Relay Service? Its literally only for sending a couple of emails a day to a list of about 20 users per client. The application only allows for the smtp server and to/from addresses to be specified. I'm assuming its using the default port. Thanks!

• Windows Vista: TCP/IP stack is smashed, how to reinstall the LAN-Devices?

  - by Ice

  the TCP/IP stack is smashed, thats why no LAN-Connections are running. I want to download the LAN drivers from another computer and uninstall and reinstall the LAN devices on this system. Hopefully that should recreate the stack. But what to download? What uninstall? How to install? Windows Vista is protected against such changes, so how to achieve that job? please help. Update per 2011-03-11: I found all the tipps and hints about "TCP/IP Repair, LSP Fix, and WinSock Fix" according to windows vista but nothing helped to bring back network access. What can i do as next step or which opportunities are left?

• Inexpensive degaussers or HDD shredders?

  - by Nicholas Knight

  I do a lot of work for a small cash-strapped business that has a lot of active hard drives, most are consumer-grade SATA of about five years of age, and predictably they are dying at an increasing rate, and a lot of the time they can't even be detected, let alone complete a zero-out cycle. Right now those drives are just being stored, but that can't continue forever. We've got a couple bad LTO tapes it'd be nice to deal with, too. There are very real security and legal issues that make dropping them off with someone who claims they'll be properly destroyed a gamble. I've looked around at degaussers and HDD shredders, and the ones that don't look like they come from some guy in his basement all seem to be $3000+, which is hard to swallow right now. Is there anything out there in the $500-1500 range that you would recommend? (Speed isn't a big issue, if it takes several minutes or even hours per drive, that's completely OK, we've only got 10 or so thus far.)

• script to automatically test if a web site is available

  - by Xoundboy

  I'm a lone web developer with my own Centos VPS hosting a few small web sites for my clients. Today I discovered my httpd service had stopped (for no apparent reason - but that's another thread). I restarted it but now I need to find a way that I can be notified by email and/or SMS if it happens again - I don't like it when my client rings me to tell me their web site doesn't work! I know there are probably many different possibilities, including server monitoring software. I think all I really need is a script that I can run as a cron job from my dev host (which is permanently running in my office) that attempts to load a page from my production server and if it doesn't load within say 30 seconds then it sends me an email or SMS. I'm pretty rubbish at shell scripting, hence this question. Any suggestions would be gratefully appreciated, thanks to all you clever sysadmin guys and girls out there :)

• Does a bad Internet connection increase bandwidth usage?

  - by Synetech

  My (Rogers) cable connection has been pretty bad recently (channels 3 and 10 are particularly fuzzy—it’s analog, not digital cable). Not surprisingly, this has caused my cable modem to drop out and have to reestablish a connection a couple of times since it started. The poor connection of course means higher corruption (not necessarily dropped per se) which causes the TCP/IP stack to have to retransmit packets more often. Reduction of bandwidth throughput aside, I got to wondering if it increases the actual bandwidth usage. That is, if there is a high error rate on the line causing packets to have to be retransmitted: Does this increase a bandwidth monitoring program’s numbers? Does the ISP count the retransmitted packets toward the monthly cap? Based on what I remember from my university networking courses and common sense, I have a feeling that the answer to both questions is yes, but I cannot reliably measure the first, and have no authoritative answer for the second. I’m wondering if maybe the retransmitted packets are acknowledged as being duplicates and thus not counted somewhere along the line.

• How to have a soft-real-time process in presense of heavily swapping IO-intensive background load?

  - by Vi

  schedtool: PID 32301: PRIO 4, POLICY R: SCHED_RR , NICE -20, AFFINITY 0xf ionice: realtime: prio 4 But the music is stumbling anyway. Background load is low prio (SCHED_IDLEPRIO, idle ionice), but uses a lot of memory (more than is physically available) and does a lot of IO and calculations. Latencytop shows about 1500ms for: Following symlink Writing buffer to disk (sync) Page fault Writing a page to disk both for the bg load and for unrelated processes. Load average is 10 and counting. Why cannot it allocate, for example, 200MHZ of one of the cores and 32M of memory and not less than once per second opportunity for IO for mplayer to make it happy while continuing calculations on the background? Or: why it cannot leave background task and swap loving each other but keeping the rest of the system as if there were no background load? How to have RT processes AND heavy bg load simultaneously (without of virtual machines)?

• Virtual hosting in Varnish with individual vcl files for configuration

  - by Michael Sørensen

  I wish to use varnish to put in front of an apache and a tomcat on the same server. Depending on the ip requested, it goes to a different backend. This works. Now for most of the sites the default varnish logic will work just fine. However for some specific sites I wish to use custom VCL code. I can test for host name and include config files for the specific domains, but this only works inside the individual methods recv etc. Is there a way to include a complete set of instructions, in one file, per domain, without having to manage separate files for subdomain_recv, subdomain_fetch etc? And preferably without running seperate instances of varnish. When I try to include a file on the "root level" of default.vcl, I get a compilation error. Best regards, Michael

• Create intentional border with xrandr

  - by benizi

  Is there a way to tell xrandr "this space intentionally left blank"? I have a laptop that drives its internal display at 1920x1080, but the external monitor I'm using, due to its different aspect ratio, doesn't have that mode. It runs at 1920x1200. So, the basic setup: xrandr \ --output LVDS-1 --mode 1920x1080 \ --output DP-1 --mode 1920x1200 --same-as LVDS-1 [not to scale:] +-----------------------------------+ ¦ ¦ ¦ ¦ (laptop) ¦ (external) ¦ ¦ (LVDS-1) ¦ (DP-1) ¦ ¦ ¦ ¦ ¦ ¦ ¦ +-----------------¦ ¦ (blank...) ¦ ¦ +-----------------+ How can I specify that the 1920x120-sized region below LVDS-1 should be displayed as a black bar that can't be accessed by mouse on DP-1? I tried just coping with --panning 1920x1200+0+0/1920x1080+0+0/0/0/0/120, but I found the screen movement to be very annoying. Update: I found a workaround. (Update 2: changed it to an answer, per suggestion -- workaround doesn't answer the underlying question of leaving space blank.)

• Streamline Active Directory account creation via automated web site

  - by SteveM82

  In my company we have high employee turnover, and hence our helpdesk receives about a dozen requests per week for new Active Directory accounts. Currently, we receive these requests simply via e-mail or voice-mail, and rarely do we have all of the information necessary to create the account. I would like to find a web application that can be used by a manager or supervisor to formalize the requests they make for AD accounts for new employees under their command. Ideally, the application would prompt for all of necessary information, and allow the helpdesk to review the requests and approve or deny each one. If approved, the application would take care of creating the account and send an e-mail to the manager. I have found several application on the Internet that handle self-service account management (i.e., password resets or update contact info), which is also nice to have, but nothing that streamlines the new account request and creation part. Can anyone make suggestions on such an application? Thanks.

• Java sound doesn't work under Linux

  - by Cliff

  I just installed Fedora 12 and after downloading and running the Java Sound Demo I get exceptions. If I run just a vanilla Java program that plays a .wav file it runs silently with no sound and no exceptions. Every other app seems to play sound. I also took some advice from this thread in the Ubuntu forums which almost seemed to work. (Installing aoss got rid of the initial exceptions in the sound demo but I still hear nothing when I play.) I'm getting frustrated by the individual hoops I have to go through to eek sound out of my speakers when running Java apps on Linux platforms! Can somebody help me figure out what's wrong?

• Alt-tab icon list in Gnome and metacity?

  - by Vinh Nguyen

  Can anyone provide a reference or explain how the icons to the alt-tab list is populated? I would like to specify some icons for some programs that do not have icons, e.g. xterm. I'm using Ubuntu 11.04 with Gnome 2 (Ubuntu Classic) and metacity as the window manager. I did see this thread that mentions /usr/share/pixmap/, but if I use cp gnome-terminal.xpm xterm.xpm the icon was not populated in the alt-tab icon list (even after a logout/login). I do see that the icon is populated when I added the xterm command to the Program Menu.

• Lingering database-connections from Feng Office

  - by Bobby

  I've installed Feng Office on our main server which is working perfectly so far. Unfortunately it seems like there's a problem with the connection to the MySQL-Database. While the connection itself works fine, it's the reuse/pooling of connections which seems to be bugged. There are lingering/sleeping connections to the server from Feng Office which won't close and don't get reused after some time (120 seconds). Of course those lingering processes/connections are piling up pretty fast. I've found a thread at the forums about this behavior, but the suggested fix is already applied (by default). I'm sure this is just a configuration issue, but I'm a little clue less because Feng is besides a MediaWiki, a DokuWiki and homebrewed PHP applications the only one with this issue. The setup is a Microsoft Windows 2003 Server with MySQL 5.0.26 and Apache 2.2. Where can I start looking for clues why this is happening and how do I get rid of lingering MySQL-Connections?

• Change/Deactivate the shell for an amount of users on SUSE Enterprise Server

  - by Manfred Schmidt

  I have a SUSE Server to which ~300 users are connecting. About 100 of them have to be deactivated. I think it would be nice to change their shell to /bin/false either with chsh or with usermod. Do I have to type every command per line, or can I fill out a list of users which can be read from the script? I should mention that all of the 100 users have the same ending in their username. Can I work with wildcards here? e.g. usermod -s /bin/fish *ftpuser chsh -s /sbin/nologin *ftpuser

• Tracking costs within one AWS account

  - by caius howcroft

  I have what I'm sure is a very common problem. Our company has many projects and groups working for different clients. We do a lot of our development work in the cloud and deploy our solutions there. We have a VPC set up that isolates projects from each other in their own subnet and that VPC is getting a hardware VPN connection back to HQ. We need to keep track of the cost run up by every project. The way I currently implement this is by providing my own tools for starting and stopping instances which log which user (and thus which project) to bill the instance too. This works okay for BoxUsage costs but not for other costs. I could create a separate account for each project and use consolidated billing, this I think would allow me to pay once but track costs per "project", but I would then not be able to share common resources (like bring account B's running instances inside the same VPC). Does anyone have any suggestions? Cheers C

• Advantages of a deployment tool over shell

  - by Jimmy

  Currently I have all of my deployment scripts in shell, which installs about 10 programs and configures them. The way I see it shell is a fantastic tool for this: Modular: Only one program per script, this way I can spread the programs across different servers Simple: Shell scripts are extremely simple and don't need any other software installed One-click: I only have to run the shell script once and everything is setup Agnostic: Most programmers can figure out shell, and don't need to know how to use a specific program. Versioning: Since my code is on github a simple git pull and restart all of supervisor will run my latest code. My question is, with all of these advantages, why is it people are constantly telling me to use a tool such as ansible or chef, and not to use shell.

• Text template or tool for documentation of computer configurations

  - by mjustin

  I regularly write and update technical documentation which will be used to set up a new virtual machine, or to have a lookup for system dependencies in networks with around 20-50 (server-side) computers. At the moment I use OpenOffice Writer with text tables, and create one document per intranet domain. To improve this documentation, I would like to collect some examples to identify areas where my documents can be improved, regarding general structure and content, to make it easy to read and use not only for me but also for technical staff, helpdesk etc. Are there simple text templates (for example for OpenOffice Writer) or tools (maybe database-driven) for structured documentation of a computer configuration? Such a template / tool should provide required and optional configuration sections, like 'operating system', 'installed services', 'mapped network drives', 'scheduled tasks', 'remote servers', 'logon user account', 'firewall settings', 'hard disk size' ... It is not so much low-level hardware docs but more infrastructure / integration information in these documents (no BIOS settings, MAC addresses).

• How do I establish the network sharing to my WinXP server network drive from my Mac notebook?

  - by mobibob

  I have been able to connect to my WinXP server's shared drives by using Finder's Command-K to browse the network. Unfortunately, when the server gets rebooted, the connection drops and sometimes I cannot get reconnected. I have specified different protocols (afp / cifs / smb) and different login names (connect as...) with limited success. Once I find the right combination, I am good for a few weeks. Once, it seems as though I had to unshared and shared the drive to get it to work. Unfortunately, it is very frustrating, so I try multiple things at one time, so when I finally get to the success point -- I honestly don't know what worked. I followed Mac help, surfed for instructions, issues, etc., but nothing appears to be consistent. I would love for this thread to be the ultimate answer for all time! Can anyone help me? If my description or question need more detail, please ask away!
