• Wall jacks to patch panel?

  - by rj454me

  OK, I'm by no means a seasoned networking pro and I had no say so in the design of our current server room which is in dire need of an extreme makeover. Basically, in our server room we have 12 wall plates with 4 RJ-45 ports on each - 48 total RJ-45 ports. From these 48 ports is a spaghetti bowl of network cables feeding our servers located in a rack - there is no patch panel currently, just straight from the wall jack to each server. What I was wondering is, is it feasible to mount a 48 port patch panel in our server rack and feed into this patch panel from the wall jacks (of course nicely routing this cable through some new cable trays)? We really don't have the funds to mount the patch panel and have it fed directly from the switches in the telcom closet which is several hundred feet away. Current: Switch (Telcom Closet) - Wall Jacks - Servers Proposed: Switch (Telcom Closet) - Wall Jacks - Patch Panel - Servers

• How can I send an email from Mail.app to Outlook with an attachment that does not embed into the email body?

  - by JAG2007

  I'm using Mail.app (on Mac OS X 10.6) and when I send an email to users on PC Outlook, with an attached image, they get the email as an image embedded into the body, not as an attachement. I even tried clicking "view as icon" before sending the attachment from Macmail, but that made no difference. I also tried this myself, sending from Mail.app over to my PC's Outlook, and I do get that same problem. In Outlook the image is not coming through as an attachment, but as an image embedded into the body of the email. The reason this is an issue primarily is because the user is then unable to click "save as" and has to actually copy and paste it into some other program, which means the file is converted from jpg or png to the bmp format. But beyond that, most of my recipients don't even know how to copy and paste it into another program to save it that way anyway. They need the "save attachment as" functionality.

• RAID10 without write-back cache = horrible write performance?

  - by Harry Mexican

  I have just provisioned a dedicated server on singlehop. I'm running it through some tests to know what to expect performance-wise. On the I/O side (with 4 1TB disks in RAID 10) I get: write-cache disabled 200 MB/s read throughput 30 MB/s write throughput I thought that was really low compared to my desktop HD which gets 150-150 or so. So I had a chat with them and they suggested enabling the write cache. New results: write-cache enabled 280 MB/s read 260 MB/s write which is great and all but means I'd have to add a BBU for an additional monthly cost. Is it normal for the write throughput to be 1/4 of a regular drive on RAID10, if you don't have write cache? It almost feels like its intentionally bad to force you to pony up for the BBU. I'd be happy with normal non-raid performance of 150/150.

• How to customize Windows 7 HAL library during installation (BSOD STOP: 0x000000A5)?

  - by koldovsky

  While trying to install Windows 7 x86 Ultimate on Samsung M40 laptop (Pentium M 1.7 Dothan, 2 GB RAM/ 100 GB HDD) i receive BSOD STOP: 0x000000A5: The bios in this system is not fully ACPI compliant. Please contact your system vendor for an updated bios. The bios on the system is updated to latest version. If ACPI is the real source of the issue it means that I possibly could use another HAL library. In Windows XP it is possible to install system with generic HAL library pressing F7 when installer asks to supply drivers, but on Windows 7 I can't find such option. Ironically, Vista installs and works nice, even if they said that Windows 7 is less demanding for hardware. Windows 7 Advisor also tells nothing suspicious. Can anybody tell me how to customize Windows 7 installer to use generic HAL library (if it is possible, of course) or point me to another solution?

• Opening Office 2007 files using a Vista or Win7 client on a server 2008 file share causes lockups an

  - by DrZaiusApeLord

  I think this mostly happens when trying to open files opened by other users. In the XP/2003 days you would get some kind of warning about a locked/read only file. With 7/Vista/2008 I'm just seeing clients hang (Word just sits there) and if I go into the file share and attempt to right-click on the file, explorer hangs for several minutes. I tried disabling AV on the file server as well as locally. No luck. I've read that SMB2.0 might be the culprit here, but even testing that solution means disabling it on both the client and server, and requires a server reboot. Does this sound like an SMB2 issue? The server is 2008 SP1. The clients are Win7 vanilla and Vista SP2 with all the current updates. Office 2007 SP2 with all updates. Thanks.

• starting nginx via upstart

  - by Chiggsy

  Background: DISTRIB_ID=Ubuntu DISTRIB_RELEASE=10.04 DISTRIB_CODENAME=lucid DISTRIB_DESCRIPTION="Ubuntu 10.04 LTS" I've built nginx, and I'd like to use upstart to start it: nginx upstart script from the site: description "nginx http daemon" start on runlevel 2 stop on runlevel 0 stop on runlevel 1 stop on runlevel 6 console owner exec /usr/sbin/nginx -c /etc/nginx/nginx.conf -g "daemon off;" respawn I get "unknown job" when i try to use initctl to run it, which I just learned apparently means there is an error, ( what's wrong with "Error" to describe errors?) Can someone point me in the right direction ? I've read the documentation , as it is, and it seems kind of sparse for a SysV init replacement... but whatever just need to add this job to the list, run it, and get on with what's left of my life... Any tips? EDIT: initctl version init (upstart 0.6.5)

• Set default expand/colapse state on pivot tables

  - by CLockeWork

  The Setup I have a pivot table in tabular form pulling data from an Analysis Services Cube. I want to calculate the number of days between two dates, but the setup will only allow me to pull in all date elements, not just the date. I’ve been able to deal with this easily enough by just grouping all the columns: The Problem The default state for the expand/collapse buttons in the image above is often collapsed, but that means the dates I need aren’t there and you have to open the group and manually expand them. This also happens in some random ways (as shown in the image) where only some rows expand. The Question I need a way to set these sections to always be expanded, so that the user never has to open the group to expand the rows. Ideally I’d like to avoid VBA because our end users often block it, but if that’s what’s needed then so be it. Is there a way to set my pivot table to never collapse it’s predefined groups? Note the end user is using Excel 2010

• Process ANSI escape codes before piping

  - by Tiddo

  I'm trying to pipe the output of a script (Mocha) to another script. However there is one problem: Mocha generates quite a few ansi escape characters to update the screen on the fly. These characters are also send through the pipe. Is there a way to process the ansi sequence such that the output is the same as the final output to the screen? I do want to keep color escape sequences, but not the curser movement escapes. Edit: I have a partial solution now (for Mocha only): so far it seems that Mocha with the spec output (the one I use) only generates color ecape characters and the CSI 0G escape sequence. The CSI 0G escape character means that the cursor should move back to the beginning of the line. Mocha uses this to overwrite a line completely. Therefore you could simply create a sed regexp which will delete everything up to that escape sequence on a line: sed 's/^.*\x1b\[0G//g'. I am still looking for the complete solution though.

• Tiling window manager where dual heads share common workspace

  - by mikero

  I want to use a tiling window manager with my dual monitor setup, but almost all wms seem to treat each monitor as an independent workspace. This means that I can change the workspace of monitor 0 without affecting the workspace of monitor 1. This is not what I want -- I want a workspace to span both monitors, where each monitor is essentially a separate column for tiling (my monitors are oriented vertically, so they are well-suited as tiling columns). When I switch workspaces, say with Mod-[0-9], I want both monitors to change contents. So far the only wm I have found to support this is wmii, but I'd love to try some other options. Have I missed this capability from other tiling wms?

• Hosting multiple sites on a single webapp in tomcat

  - by satish

  Scenario: I have a website - www.mydomain.com. Registered users will be given the choice of getting a permanent url to their account on mydomain.com as a subdomain like (username.mydomain.com) or they can opt to have their own domain like www.userdomain.com. So the user can access his/her account through the subdomain URL or their own hostname and the request should be forwarded to a specific url on mydomain.com. For example: xyz.mydomain.com or www.xyz.com should give the user account from www.mydomain.com/webapp/account?id=xyz. The user should be completely unaware about where the content is coming from. Setup: My website is running as a webapp in tomcat 5.5.28 with apache as the web server. I am using a VPS which means I have control over all the configuration files (apache, tomcat and dns server). Can you tell me what are the configurations needed to achieve the above scenario??

• tag structured Filesystems

  - by A.Rashad

  I hope this is the correct site, I lose my way between the 4 sister sites :) Let me ask the question this way. all file systems I have seen before are hierarchical, that means a root directory, with some branched directories, and so on until we have files residing in these directories. except for AS/400 file structure, where it has a concept of a Library that serve somehow as a directory but one level only. Why not have directory-less filesystems where files are placed in a single location, but the file identifiers would be referenced by a database of tag/ file relation ships. This way there will be no need for symbolic links, one file may have multiple relations to multiple subjects, not only a single parent directory to contain. I hope the idea is clear.

• Installing PHP with iconv on Mac OSX 10.6 gives error: "Undefined symbols for architecture x86_64"

  - by Jason

  I am setting up PHP on my local web server with iconv, which should be there by default, but I am getting the following error: Undefined symbols for architecture x86_64: "_iconv", referenced from: __php_iconv_strlen in iconv.o _php_iconv_string in iconv.o __php_iconv_strpos in iconv.o __php_iconv_appendl in iconv.o _zif_iconv_substr in iconv.o _zif_iconv_mime_encode in iconv.o _php_iconv_stream_filter_append_bucket in iconv.o ...

In my config.lob file, it says at the bottom: configure: exit 77 Any suggestions?

• Mantaining Wordpress website with subversion

  - by Geries

  I want to setup a website using wordpress, which we can modified locally and then via subversion commit the site and make it public. This means to installing new plugins, changing the content, testing updates of wordpress to see if they work with the theme, etc. The idea is to control the development on the site, in case we need to keep track of the dev or roll back, because of unexpected bugs in a the plugins, theme, etc. I've read this article in codex, however I'm not sure how this is done when, we want to include the content and changes on the options of worpdress and plugins (which is in the mysql). Thanks

• VirtuaWin shows Visual Studio 2010 in all Desktops

  - by w0lf

  I'm using VirtuaWin in Windows 7 to have virtual desktop functionality and I think this program is awesome. There's one small issue, though: on the computer at work, when moving to another desktop it hides all windows in the current desktop, except any windows of Visual Studio 2010. This means that VS 2010 shows up in all desktops, while for all other windows, VirtuaWin applies the correct behavior. The strange thing is that this issue happens on one computer only; on the others I have it works OK. I have checked the Window Rules section and nothing seems strange in there. Is anyone else experiencing this kind of problem? Any ideas on how to solve it?

• How can I shrink the Address toolbar in the Task Bar?

  - by Iszi

  I like being able to run commands straight from my Task Bar. So, I've enabled the Address toolbar on my new Windows 7 system - just like I had on my old XP system. However, the bar seems to have a mandatory minimum length that's a bit longer than I'd prefer. It's about twice as long, if memory serves, as the minimum size allowed in XP. Is there any way I can adjust this minimum length, through a Registry key or some other means? (Note: I've also got a related question, about removing the Refresh button at the end of the bar.) EDIT: For clarity, I'm adding a screenshot. The toolbar I want to shorten is the one circled below, with an empty text-entry field that has a drop-down and "Refresh" button. I currently have it positioned between a Quick Launch toolbar and the Taskbar. On the far side of the Taskbar, before the System Tray, is a Desktop toolbar.

• Is there a version of the Arial or Tahoma font with monospaced digits and spaces?

  - by rossmcm

  The digits in the Arial font supplied with Windows are monospaced, in that they each take up the same horizontal space, but they seem to have neglected to provide a "monospaced" version of the space character. This means that you can't format a column of digits right-justified in (say) 12 spaces and have the right-hand edge be aligned. For example: 1 12 123 1234 12345 1234567 12345678 123456789 1234567890 works because the font used for code examples has spaces the same width as digits. This however doesn't work if the same text is displayed in Arial (I can't demonstrate because I can't figure out how to defeat SU's reformatting at the moment!). It just so happens that with Tahoma 8 point you can cheat because a space is exactly half the number of pixels as a digit, but that is messy and very specific.

• How to allow program updates without prompting UAC?

  - by Ryan Mortier

  We have about 15-20 users who have this software installed. We have UAC enabled through GPO as you should, which means the software prompts for admin approval if a standard user trys to install it. Thats fine, they can call the help desk to have the software installed. My problem is, our help desk is being bombarded every day because users can't update the software and there are updates almost every day which is prompting UAC. Using procmon.exe to find out where it was trying to write to, I then created a GPO to allow file permission access to the program files folder for this particular software, including the program data folder, but it still prompts for admin approval. It seems as though that the software is using msiexec.exe to run a .msp patch file. The only "ACCESS DENIED"s I can still see in procmon is things like this: What can I possibly do to stop this software from prompting UAC with admin password credentials aside from disabling UAC?

• Does openssl errno 104 mean that SSLv2 is disabled?

  - by David

  I want to check if my server has SSLv2 disabled. I am doing this by attempting to connect remotely with openssl with the following shell command. openssl s_client -connect HOSTNAME:443 -ssl2 Most literature I could find on the Internet says if I see something similar to the following error then SSLv2 is properly disabled. 29638:error:1407F0E5:SSL routines:SSL2_WRITE:ssl handshake failure:s2_pkt.c:428: I do get the above error when connecting to my Ubuntu server with SSLv2 disabled in Apache Apache but when I connect to my Windows Server 2008 R2 server with SSLv2 disabled in the registry I get the following output and error. CONNECTED(00000003) write:errno=104 I can't find any literature explaining this output and error. If anybody could explain to me if and why this output and error means that SSLv2 is properly disabled, I would appreciate it. Thanks!

• Recommended RAM and disc space for Oracle 11g on Windows

  - by Álvaro G. Vicario

  I need to provide the recommended amount of RAM and disc space (divided in two partitions) so the customer can create an appropriate virtual machine to run Oracle. All I could find in the documentation was a brief listing with minimum RAM and typical/advanced install types. The virtual machine will run latest Oracle Standard Edition One (11g release 2 so far) under Windows Server 2008 x64 and will host a reasonably low traffic web application. How much RAM and disc must I ask for in order to be safe? (Feel free to ask for further details if I've omitted something relevant.) Update: Rough estimations: Database size: 10 MB after installation Growth rate: +3MB per day on average Size of database 'active' data: (not sure of what this means, there's not actual archive so I guess all data is current) Amount of data written per second in peak hours: a few KB Number of client sessions: 3 or 4 at most Frequency and response size of most heavy requests: some reports make heavy table JOINS that need up to 20 seconds to complete but they won't return more than a few thousand rows with plain text. The app also handles BLOBs (typical size from 50KB to 200KB)

• TIME column in TOP command for mysql

  - by michael

  When I run top on my database server I get that mysqld has been running for 4:00.51 and it continues to go up. I assume this means that one process with mysql has been running this long from other posts on here. Its not set to cumulative mode as best I can tell as the heading looks like it would change to CTIME if that be the case. What I'm wondering is if this is normal for a site that makes a lot of individual connections using PHP. I shouldn't have any long running processes that would hold on to a mysql connection for this long, only seconds at most. Am I incorrect to assume that this time relates to one connection/process running? I think usually I see it flash up and away on the TOP, not just stay there with this number increasing.

• How to configure nginx to serve static contents from RAM?

  - by Vijayendra Tripathi

  I want to set up nginx as my web server. I want to have image files cached in the memory (RAM) rather then disk. I am serving a small page and want few images always served from RAM. I dont wish to use varnish (or any other such tools) for this as I believe nginx has a capability to cache contents into RAM. I am not sure as how may I configure nginx for this? I did try few combinations but they didn't work. nginx uses disk all the time to get images. For example, when I tried apache benchmark to test with following command - ab -c 500 -n 1000 http://localhost/banner.jpg I get following error - socket: Too many open files (24) I guess this means nginx is trying to open to many files simultaneously from the disk and OS is not allowing this operation. Can anyone please suggest me a correct configuration? Thanks for considering this message.

If it is something to worry about, then any pointers on how to fix the problem are appreciated.

• Postfix Inbound/Outbound Gateway for Google Apps

  - by geofflee

  I currently have a Postfix/Dovecot setup, but our server is hitting capacity, so we decided to switch to Google Apps. However, we have certain web applications that need to send and receive e-mail directly (for example, e-mail being redirected to a script). What I want to do is host certain e-mail accounts with Google Apps, while my current server continues to manage other e-mail accounts. I assume this means that I would use my current server as an Inbound/Outbound Gateway, so my questions are: 1) How do I setup Postfix as an Outbound Gateway without making it an (insecure) open relay? 2) How do I setup Postfix as an Inbound Gateway so that only certain e-mail addresses are forwarded to Google Apps? Thank you!

• Running remotely an app from a shared folder with PsExec

  I am actually not sure that this is possible. let's see: I have a script that runs on a Build server. Let's name this server A. It drops the bins to a shared folder on server B. And I want to run the program on server C. So using caspol I can allow the executable to be ran remotely. that means from B I can run \C\shared\my.exe What I want to do is from A run \C\shared\my.exe on B. SysInternals\PsExec.exe -u username -p password -accepteula \\ServerC -i 0 -d -w \\ServerB\Nightly\Server \\ServerB\Nightly\Server\server.exe The user has all the necessary rights. But, the -w (working directory) options apparently wants a path relative to the server I point to. Any idea?
