• Which isn't working on linode servers (Ubuntu 10.04)?

  - by chrisjlee

  Currently trying to configure a linode server running on ubuntu 10.04. I utilized a stackscript (Default drupal profile) which seemed to run successfully. The log indicate so as well. Then ssh'd into the server (as root) to try to configure php. When i run a which php, which php5 they both return nothing. A which python returns something though. I know where the default path to php but i usually just like to use it as confirmation that php exists. Do i have to modify some configurations to enable which to work? Also tab completion doesn't seem to work for when i apt-get install? Update: Thanks for the suggestions guys. I've ran a couple commands and no luck either: [ root@ ~ ] $ dpkg -l |grep php [ root@ ~ ] $ apt-get install php5-cli Reading package lists... Done Building dependency tree Reading state information... Done Package php5-cli is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package php5-cli has no installation candidate Then i tried installing php and php cli: [ root@ ~ ] $ sudo apt-get install php5 php5-cli sudo: unable to resolve host xxxxxxx Reading package lists... Done Building dependency tree Reading state information... Done Package php5 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package php5 has no installation candidate

• Samba doesnt require password on xbmc but does on ubuntu

  - by Chris

  I have samba setup on a fedora 13 machine, and I use it to share with my xbmc client in the family room. When I set this up there no password or anything was required I merely entered in paths such as: smb://<host>/<share> and all worked. Now on my ubuntu 10.04 machine when I try to access the same hosts, for example through smbmount though I receive an error. smbmount //media/Music ~/Music/ # media is in my /etc/hosts and resolves to # correct IP address for the machine I receive error: operation not permitted after pressing enter when it prompts for password.

• Effective Permissions displays incorrect information

  - by Konrads

  I have a security mystery :) Effective permissions tab shows that a few sampled users (IT ops) have any and all rights (all boxes are ticked). The permissions show that Local Administrators group has full access and some business users have too of which the sampled users are not members of. Local Administrators group has some AD IT Ops related groups of which the sampled users, again, appear not be members. The sampled users are not members of Domain Administrators either. I've tried tracing backwards (from permissions to user) and forwards (user to permission) and could not find anything. At this point, there are three options: I've missed something and they are members of some groups. There's another way of getting full permissions. Effective Permissions are horribly wrong. Is there a way to retrieve the decision logic of Effective Permissions? Any hints, tips, ideas? UPDATE: The winning answer is number 3 - Effective Permissions are horribly wrong. When comparing outputs as ran from the server logged on as admin and when running it as a regular user from remote computer show different results: All boxes (FULL) access and on server - None. Actually testing the access, of course, denies access.

• Mouse clicks suddenly stopped working in Ubuntu

  - by DisgruntledGoat

  This is a weird one. For some reason, last night my mouse partially stopped working. Movement is fine, but the mouse buttons don't work. Mainly it's the left button, but occasionally the right click and scroll-wheel fail too. Initially I thought it could be the mouse itself (the left button seemed to get a bit "soft" recently), but I tried another mouse and had the same issue. Both are USB wireless optical mice. The keyboard is working okay 95%, only problem is Alt+Tab doesn't seem to work. Both keys work fine independently. At the time it happened I was using Chrome, I dragged to scrollbar to scroll and when I released the mouse it was still holding scrollbar. I'm using Ubuntu 9.10, I upgraded weeks ago and everything was working fine so I don't think it's related to that. I also hadn't run any updates (I have now just in case something fixed it). But no luck. Any ideas?

• Certificate enrollment request chain not trusted

  - by makerofthings7

  I am working on a MSFT lab for Direct Access, and need to create a Web certificate. The instructions ask be to do the following: On EDGE1, click Start, type mmc, and then press ENTER. Click Yes at the User Account Control prompt. Click File, and then click Add/Remove Snap-ins. Click Certificates, click Add, click Computer account, click Next, select Local computer, click Finish, and then click OK. In the console tree of the Certificates snap-in, open Certificates (Local Computer)\Personal\Certificates. Right-click Certificates, point to All Tasks, and then click Request New Certificate. Click Next twice. On the Request Certificates page, click Web Server, and then click More information is required to enroll for this certificate. On the Subject tab of the Certificate Properties dialog box, in Subject name, for Type, select Common Name. In Value, type edge1.contoso.com, and then click Add. Click OK, click Enroll, and then click Finish. In the details pane of the Certificates snap-in, verify that a new certificate with the name edge1.contoso.com was enrolled with Intended Purposes of Server Authentication. Right-click the certificate, and then click Properties. In Friendly Name, type IP-HTTPS Certificate, and then click OK. Close the console window. If you are prompted to save settings, click No. In production, our company has overridden the Web Server template and it doesn't seem to be issuing certificates with the full CA chain. When I look at the issued certificate properties then both tiers of the 2 tier CA hierarchy are missing. How can I fix this? I'm not sure where to look outside the GUI.

• Word 2010 creates multiple processes... sometimes

  - by Bill Sambrone

  I've run into a strange behavior when I migrated our users from Office 2007 / Vista to Office 2010 / Windows 7 (all 32-bit). They use a web based document management system called NetDocuments which stores all their .doc/.docx files. Generally, when they click on a doc from the browser window it fires up Word and opens the doc. Word has an add-in in it from NetDocs as well so it can upload the changed document directly back to the NetDocs server. I get a phone call when Word crashes, and every single time it has crashed I have witnessed multiple winword.exe processes running in task manager. I used process explorer to see what created the process, and it is all Internet Explorer. So far I have rolled them back to IE8 and the problem happens less frequently, but it still happens. When I try to duplicate the problem, I can make it happen sometimes if I open multiple documents very quickly. Using lightning fast alt-tab reflexes, I DO see that a 2nd WinWord process is created when a user clicks on a document, then it closes once the document is open. I think what is happening is that the secondary WinWord process that does some sort of NetDocs voodoo is getting stuck open. This behavior is new to Word 2010 / Windows 7 and google searching isn't coming up with much. I have seen a few posts that this is a known issue in certain circumstances and there is no "fix", but I thought it would good to ask others on this. Thanks!

• Where is my VMware-ws FreeNAS CIFS(ZFS) bottle-neck?

  - by maka

  Background: I'm building a quiet HTPC + NAS that is also supposed to be used for general computer usage. I'm so far generally happy with things, it was just that I was expecting a little better IO performance. I have no clue if my expectations are unreal. The NAS is there as a general purpose file storage and as a media server for XBMC and other devices. ZFS is a requirement. Question: Where is my bottle-neck, and is there anything I can do config wise, to improve my performance? I'm thinking VM-disk settings could be something but I really have no idea where to go since I'm neither experienced with FreeNAS nor VMware-WS. Tests: When I'm on the host OS and copy files (from the SSD) to the CIFS share, I get around 30 Mbytes/sec read and write. When I'm on my laptop laptop, wired to the network, I get about the same specs. The test I've done are with a 16 GB ISO, and with about 200 MB of RARs and I've tried avoiding the RAM-cache by reading different files than the ones I'm writing ( 10 GB). It feels like having less CPU cores is a lot more efficient, since the resource manager in Windows reports less CPU-usage. With 4 cores in VMware, CPU usage was 50-80%, with 1 core it was 25-60%. EDIT: HD ActiveTime was quite high on SSD so I moved the page file, disabled hibernate and enabled Win DiskCache both on SSD and RAID. This resulted in no real performance difference for one file, but if i transferred 2 files the total speed went up to 50 Mbytes/s vs ~40. The ActiveTime avg also went down a lot (to ~20%) but has now higher bursts. DiskIO is on ~ 30-35 Mbytes/s avgs, with ~100Mb bursts. Network is on 200-250Mbits/s with ~45 active TCP connections.

• Client unable to access OWA website after temporarily changing SSL certificate on the server

  - by Lorenz Meyer

  I have the following issue: One client computer (Windows XP) cannot access the OWA website. All other client computers can (Except another one in the same remote office). How this happened: I temporarily changed the SSL certificate on the Exchange Server yesterday. After a few minutes, I reverted back, an now the same certificate that was installed for years is back again. During these few minutes, they were in OWA on this computer and got a certificate error. What exactly happens: Internet Explorer displays the error Internet Explorer cannot display the webpage, Firefox displays The connection was reset and Crome shows This webpage is not available. The connection to ... was interrupted. What I already did to try to get this working: Restart the client computer Restart the exchange server Deleted Internet Explorer browsing history In IE, Internet Options, tab Content, under Certificates deletes SSL cache Restored Internet Explorer to the default parameters I looked into certmgr.msc, but did not find a certificate related to the issue What could I do else to narrow down the origin of this problem (or better: resolve it) ? Can you give any advice ?

• Understanding !d command in sed with respect to saves

  - by richardh

  I have a directory of tab-delimited text files and some have comments in the first few lines that I would like to delete. I know that the first good line starts with "Mark" so I can use /^Mark/,$!d to delete these comments. After this deletion I have several other replacements that I make in the (new) first line that has variable names. My question is, why do I have to save sed's output to get my script to work? I understand that if I line is deleted, then the output doesn't proceed downstream because there is no output. But if I don't delete (i.e., !d) then why do I have to save to file? Thanks! Here is my shell script. (I'm a sed newbie, so any other feedback is also appreciated.) #!/bin/bash for file in *.txt; do mv $file $file.old1 sed -e '/^Mark/,$!d' $file.old1 > $file.old2 sed -e '1s/\([Ss]\)hareholder/\1hrhldr/g'\ -e '1s/\([Ii]\)mmediate/\1mmdt/g'\ -e '1s/\([Nn]\)umber/\1o/g'\ -e '1s/\([Cc]\)ompany/\1o/g'\ -e '1s/\([Ii]\)nformation/\1nfo/g'\ -e '1s/\([Pp]\)ercentage/\1ct/g'\ -e '1s/\([Dd]\)omestic/\1om/g'\ -e '1s/\([Gg]\)lobal/\1lbl/g'\ -e '1s/\([Cc]\)ountry/\1ntry/g'\ -e '1s/\([Ss]\)ource/\1rc/g'\ -e '1s/\([Oo]\)wnership/\1wnrshp/g'\ -e '1s/\([Uu]\)ltimate/\1ltmt/g'\ -e '1s/\([Ii]\)ncorporation/\1ncorp/g'\ -e '1s/\([Tt]\)otal/\1ot/g'\ -e '1s/\([Dd]\)irect/\1ir/g'\ $file.old2 > $file rm -f $file.old* done

• Word 2010, Multiple Columns, Vertical center one column only

  - by Nancy N Jones

  I am creating a document with two columns in Microsoft Word 2010. I want the first column to be centered vertically. I want the second column to be on the same page and the vertical placement to be from the top. I highlight my text in the first column that I want centered vertically, then go to Page Layout Margins Custom Margins Layout, you can choose to center the vertical alignment. I have choosen the "Section Start" to be "Column" and also tried "Continuous." In all cases it always shifts all of my second column information to a new page. I don't want my second column text to be on a new page, I want it to be on the same page and vertically aligned from the top--not the center. Am I understanding the functionality of the Section Start on the Layout tab correctly? Maybe the page layout isn't the correct formatting to use. What I am really doing is formatting columns. I haven't found anywhere to format the columns for this. Am I missing some important column formatting features? I know that I can use the paragraph formatting and add space above the first line of text to make it look like it is centered vertically. However, this is a template for a master document and will be changed frequently. I really would like the first column text to be automatically formatted to be centered vertically without having to go in and manually change the space above the paragraph every time. Your assistance would be greatly appreciated.

• Java website on Tomcat PHP website on Apache - how to get PHP web pages into Java web pages?

  - by Venkat

  We have a Java web application deployed on Tomcat. We also setup Apache and mod_proxy_ajp to route web requests (port 80/443) to Tomcat. We would like to deploy a PHP application on the same Apache server - probably under a subdirectory (/var/www/ourapp). Now we would like to access & display web pages from PHP application within web pages generated by Java application. Planning to implement Single Sign-on as well. Example: Web page from java has (JQuery Tabs) and we like to display the PHP web page within a tab while all other HTML comes from java application. Can you please give a overall picture of how to proceed about this? Mainly 1. how we should install/setup our PHP application on same Apache server which is used to route web requests to Tomcat? i.e. either setup sub domain or install in sub directory 2. How to bring PHP pages into present web pages (generated by java). Can we use AJAX requests or should go for Java PHP Bridge/ Querces such applications? Thank you for your time in advance. Regards.

• Windows 7 search does not return results from indexed folders

  - by Dilbert

  I am experiencing this issue over and over again and I just cannot seem to find the answer. It doesn't make sense, but search simply does not return results from folders that certainly have these files inside. It's weird that this technology exists for more than 5 years now (it could be added to Windows XP as an addon), and they still haven't got it right. My folder contains 10 image files with .png extensions. Two scenarios: Scenario 1: I exclude the folder using Indexing options. Search works. Scenario 2: I turn on indexing for this folder. Search does not work. Of course, Agent Ransack returns results every time. When I check Advanced options for the Indexing options inside control panel, .png files are checked in the File Types tab, using the "File Properties filter". What's the deal with this? [Edit] To clarify, this doesn't happen with all folders, but does with more than one. For the "problematic" folders, even *.* doesn't return a single result. I found some advice to clear the archive and readonly attributes for all files (doesn't make sense, but hey), but it didn't work. Indexing status in Control panel is: Indexing complete. 100,000 items indexed. Folder is included in the list. File types list contains the .png extension (although it doesn't work with any filter, not even *.*).

• Search behavior of Windows 7 start menu

  - by Kevin Ivarsen

  I'm coming to Windows 7 from XP, and there are aspects of the start menu search that I like. However, there are some behaviors that seem either inconsistent or surprising to me. For example: If I type "Pa" into the search bar, Paint is the first result (under the "Programs" heading), and it is selected for me. I can just hit Enter to start the program If I have a standalone exe "testing" on my desktop, and I type "test", the program comes up as the first item (under the "Files" heading), but it is not selected for me. I have to hit down-down-down-enter to open it from the keyboard. The same appears to be true for shortcuts and folders. What classifies something as a "Program" verses a "File"? Is there any way to configure the start menu so that the first search result is always selected? As a heavy keyboard user, it seems insane for the behavior to be inconsistent, and to require so many keypresses to select the top result. Also, are there resources that document the details, limitations, and tricks of the start menu search? (For example, a "Proc Exp" search will match "Process Explorer", but not "ProcessExplorer") EDIT: I've found that instead of hitting down-down-down to select the first item (when no Programs are in the list), you can just hit tab. This helps a bit, but the inconsistent behavior still makes this search feature more awkward and frustrating than necessary.

• How can I enable IIS to run Perl scripts?

  - by eidylon

  we're trying to get awstats up and running on our IIS6 server. awstats is running fine and generating output and all that jazz... no problem there. When trying to change the selected month/year in the output page though, it is trying to run awstats.pl through IIS, and coming up with a 404 error. To debug I made a simple hello.pl in my root, and tried to run that, also 404s. I followed the directions on this page http://support.microsoft.com/kb/245225 regarding installing ActiveState Perl and then configuring IIS. I added the extension mapping on my directory and registered the web services extension as directed. The perl scripts all run fine and output if run from the command line, so I know perl is good, but I can't get IIS to find the files. Here is the configuration on my the home directory tab of my site: Here is the configuration of my web service extension: I turned on directory browsing for this site, and when i get the listing of the directory, IIS actually does show the .pl files being in the directory. But if I click on one of them, I get the 404 error. 12/17 15:22 Also tried adding .pl as a mime-type on my site's configuration. This did not help. 12/17 16:57 Also tried Everyone Read/Execute permissions on both the Perl direcory and the directory housing awstats. This did not help.

• Merely installing PHP5 causes my AWS Ubuntu server to die minutes later from a massive CPU spike

  - by Mark Amery

  I have an AWS server with Ubuntu 11.04 as the OS that is running an Apache2 webserver (incidentally Python-based and using Django). We recently needed to add support for php5 to let us use a third party PHP library (incidentally for serving minified versions of js and css files). However, for no reason any of us can discern, if we simply run sudo apt-get install php5 on the server, then the install appears to finish successfully but, without us taking any further action (including not yet running sudo apt-get install libapache2-mod-php5, which I think would be the next step for us if everything worked), or actually running any PHP scripts on the server, a few minutes later the server becomes impossible to connect to, and looking at the 'Monitoring' tab for the server in the EC2 Management Console reveals that a while after the installation, CPU usage spikes to 100% and stays there permanently (until we reboot the server from the AWS Console). After rebooting, the server also reliably dies within a few (between 0 and 10) minutes. We restored the server to a pre-PHP state from an AMI Image, observed that it was stable, and then tried installing PHP5 again and observed the server die in exactly the same way, so we're pretty much certain that installing PHP5 is what causes the symptoms. What on earth could be causing this behaviour, and how can we get PHP installed on the server without it dying?

• Relaying to tech "support" that computer is actually broken.

  - by Sion

  First some background: I have a Dell Inspiron 15R M050, it is still under the Dell limited warranty and the Best Buy Extended warranty. I am currently dual booting Debian Squeeze and Windows 7, the only reason I go into Windows is to play video games specifically steam games. Issue: When I play my games in Windows I am capable of playing for anywhere from 5 minutes to 2 hours before I suffer a hard-lock. I cannot alt-tab, ctrl-alt-delete, ctrl-shift-escape do anything for 2-3 minutes. After this hard-lock period everything runs fine, I can continue the game for probably another hour at least before I suffer another lock. Games: Borderlands, Splinter Cell: Chaos Theory, Starcraft 2, Garrys Mod What I have tried: Running the diagnostic suite in the dell bios, restoring the OEM Windows recovery partition on the HD, fresh installing Windows 7 Professional, updating BIOS, Calling tech support and having them run a software Hardware Diagnostics suite. The question: I think from the research that I have performed that it might be a lack of thermal paste on the CPU, would I be able to go to Best Buy and have them do a hardware diagnostic from the hardware level then have them be able to tell Dell that there is a hardware issue? Or would there be a different problem?

Sorry about the warning, obviously i'm not here to get anyone infected or anything like that. Basically I run the website sortitoutsi dot net. Ages ago I got a virus on my computer, they got hold of my FTP passwords and added some lines of javascript to the top of my site. I removed them and believe it was fixed. However i'm using the "Web Developer" extension for Firefox and chose to view all javascript on my page and find there are various links to horrible urls such as: gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/aboutus.org/aboutus.org/google.com/skycn.com/torrents.ru.php and gittigidiyor-com.excite.co.jp.webmasterworld-com.eastmusicdirect.ru:8080/index.php?jl= These terms do not appear anywhere. In the source code, in any of the javascript or the css. I also can't see that there are any rogue images that I don't recognise either. So i've no idea where this javascript is coming from. Can anyone suggest how I can find references to these links and remove them? I can see them both in the Web Developer firefox extension and in the net tab using Firebug. Any help would be greatly appreciated

• Gigabit LAN not working on ASUS M2N-MX

  - by chmod

  Today I replace my FastEthernet switch with a newly bought gigabit switch (DGS-1008A). All computers in my house are displaying that the connection speed is 1 Gbps except for one. The computer that is not working is an ASUS M2N-MX which contain an onboard gigabit NIC. See ASUS link for confirmation http://www.asus.com/Motherboards/AMD_AM2/M2NMX/ Here are some info of the machine OS: Windows 7 Ultimate SP1 64bit BIOS version: 1004 (latest) Driver: installed via Windows update (latest from Windows update) Windows Update: fully updated The machine is reformatted 3 days ago, so it's pretty clean, no junk, no virus, etc Cable: Amp CAT5E 5 meters In device manager, the name of the NIC is "NVIDIA nForce 10/100/1000 Mbps Ethernet" What I have try: I did try to install the driver provided in ASUS website, but there isn't any for Windows 7 64 or Vista 64. I did try to install the latest nForce340/6100, downloaded from Nvidia website. However, the LAN driver refuse to install, it complain that I already have the best driver installed. I looking in the property -- advance tab -- Speed/duplex settings, in an attempt to force it to run at 1000Mbps, but there is no 1000Mbps choice, only 10 and 100Mpbs. I change the CAT5E cable (use one from another computer that is running gigabit without problem) Anyone have this issue or know how to solve it? Thanks

• cannot send mail to postfix /w iptables linux proxy

  - by Juzzam

  I have two separate servers, both running Ubuntu 8.04. Server 1 has the real domain name of our site, let's refer to it as example.com. Server 2 is a mail server I have setup with postfix/courier. The hostname for this server is mail.example.com. I've setup iptables on Server 1 to forward all traffic on port 25 to Server 2. I used this script (except I changed the target ip address and the port from 80 to 25). When I send an email to [email protected] it works. However, when I try to send an email to [email protected] from gmail, I get this error: 550 550 #5.1.0 Address rejected [email protected] (state 14) /var/log/mail.log shows no new lines when this happens. What is strange is that it works with telnet from my local machine.

• Reliable custom Windows shortcut keys?

  - by Peter Baer

  I have global Windows shortcut keys assigned to several different cmd.exe instances. I do this by creating shortcuts to cmd.exe on my desktop, and assigning each one a unique shortcut key (for example, CTRL + SHIFT + U). Pretty basic stuff. I'm using Win2K8 (R1 and R2). This works just fine... most of the time. But with infuriating regularity, sometimes it doesn't. Or it will work with a long delay (many seconds). It doesn't matter what app currently has focus (it can even be one of the command prompts). It doesn't matter what keys I assign (I've tried a few variations of WIN, CTRL and SHIFT). I did notice that this is often, but not always, correlated with explorer.exe struggling in some way or another (say, an explorer window opened to a file share that's unavailable, or an app being unresponsive, or whatever). In other words the shortcut key handling appears to be very sensitive to unrelated system activity. Note that whenever I have this problem I can always successfully ALT + TAB to the window I want to get to, but that's tedious. I use the shortcuts to these command windows hundreds of times a day so even a 1% failure rate becomes really annoying. Is there a way to fix this, or is there some third-party utility out there that will RELIABLY intercept custom key combinations to bring focus to whatever apps I want, in a way that is independent of other system activity? ADDENDUM: There is a property of the Windows shortcuts that I would not want to lose if switching to a third-party hotkey tool: Windows shortcuts are idempotent. Once you've launched a shortcut to some app, pressing the shortcut key combo again takes you to the already launched process - it does not launch a new process.

• Disable or remove filter driver for single HID device

  - by snoopen

  Running Windows XP in a corporate setting here. I have an issue where a filter driver is interfering with the functionality of different USB HIDs. For example graphics tablets do not respond while the filter driver is in place. I've also had the issue with foot pedals used with transcription software. My question is really two fold: A) what makes Windows use a filter driver on one HID but not another? B) when a filter driver is causing conflicts how can I disable it on the affected devices? Background I've previously narrowed down the issue to the filter driver by uninstalling the software (Funk Proxy Host) responsible for the filter driver. The software is a type of RDP we use here at work. (I might have even booted into safe mode and renamed the file, I forget). I believe the filter driver is present to disable or modify the use of the local keyboard and mouse while admin staff are assisting users. Either way I don't have the authority to just go uninstalling this software. As far as I can tell the software versions are the same, however I'm not sure if the device driver definitions are all the same as I don't know where these things would be located. To check for the presence of the filter driver I locate the hardware device in Device Manager, click Properties Driver tab Driver Details.... It shows up as ph32ihid.sys. Even though all machines are meant to have the same SOE and do have Funk Proxy Host installed I don't always have issues with the same HIDs. A few machines here the foot pedals without any issues. I've not had any machines work with the graphics tablet without uninstalling Funk software. Driver details I've just read up a bit more about filter drivers and found the drivers description in the registry under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ProxyHostHIDFilter" There it's called "Kernel-mode HID filter driver for the Proxy Host". Presumably I could also disable it here but that would be system wide which is probably not desirable?

• Google Chrome is running my system out of memory

  - by jasondavis

  I am running Windows 7 x64 with 12GB of RAM I often have multiple windows and a ton of tabs open. I use the extension Session Buddy to restore all my windows and tabs once the memory gets too high. So my 12gb of ram will get up to around 93% used because of Chrome, now I can close chrome down and restore the same amount of windows and tabs and it will only use about 25% of memory, it then over time increases back up to the 90% zone after several hours. It seems that when I close tabs, instead of freeing that memory up, it doesn't so that is why the huge increase of memory usage as new tabs are opened and closed it just adds up, this sounds like a huge bug in chrome. Just for an example I just re-booted my system, I only have 1 window with 4 tabs open and in the task manager, it shows 29 chrome.exe processes I then killed all chrome processes and opened a chrome window with just 1 tab, it made 27 chrome.exe processes. Is this an issue that others have? More importantly, is there a fix? UPDATE I just read that each plugin and extension creates a chrome.exe process, I then couunted 24 extensions so that helps explain a portion of the large processes. Still not sure about memory not being freed up though!

• Finding default gateway in an openvpn environment in windows

  - by Alexander Trümper

  I need to find the default gateway in a openvpn scenario where the route output looks like that: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.49.73.1 10.49.73.24 10 0.0.0.0 128.0.0.0 10.8.0.1 10.8.0.2 30 So I googled around a bit and a found this script here: @For /f "tokens=3" %%* in ( 'route.exe print ^|findstr "\<0.0.0.0\>"' ) Do @Set "DefaultGateway=%%*" echo %DefaultGateway% This works, but matches both lines in the route output. But I need to find this line: 0.0.0.0 0.0.0.0 10.49.73.1 10.49.73.24 10 So I tried to modify the findstr parameter like this: findstr "\<0.0.0.0\>.\<0.0.0.0\>" in the expectation that '.' will match for the tab between the columns. But it doesn't. It will still set DefaultGateway to 10.8.0.1 I couldn't find a clue in MS documentation either. Maybe someone knows the right expression? Thanks a lot.
