How to set WAN side buffers for WRT54GL running Tomato Firmware

- by Vickash

I've recently set up a machine running m0n0wall to try and fight buffer bloat and do some traffic shaping. It was more convenient (geographically speaking) to connect the cable modem directly to my old WRT54GL, then pass everything to the m0n0wall machine and have that do the real routing work. It took a bit of work, but it's working pretty well. I have a cable connection. I have m0n0wall set up to utilize only 90% of the specified speed of my subscription, which is fine. But I've noticed that at certain times of the day (possibly when my true bandwidth drops below that 90%), there's more latency if the connection is used heavily, and traffic shaping doesn't seem to work as well. I suspect this is caused by the buffers on the WRT54GL still being unnecessarily large. If the connection is working as expected, they won't get filled, but in times of reduced bandwidth they would. Does anyone know the command I need to execute, on the WRT54GL running Tomato Firmware, to reduce the buffers on the WAN interface to the minimum size possible?

Is there a registry key change that will by-pass the Windows Domain Join Welcome page?

- by user1256194

I'm scripting some Windows Server 2008 R2 builds using Power Shell. Some software needs to be installed after the server has joined the domain. Since I want to automate everything, I'm looking to by-pass the domain controllers Welcome page using a registry hack script. I work for a large company and the Active Directory people are unwilling to change group policy. I figure if it's a registry key I can script the change, install the software, replace the key and reboot as the final step. Is there a registry key change that will by-pass the Domain Join Welcome page?

Multiple Schedule/Task Views (devs, customer, etc) in MS Project (or other)

- by ThePlatypus

Is there a way to configure multiple views/filters in MS Project for the same set of tasks? I want to have a view that is configured for customer's only, for example. So, it would have large milestone tasks only, and hide all of the details that are there for the benefit of the team members. If MS Project doesn't do this, is there any project management software that does? A free/open source version would be preferable. Edit: Apparently, "filter" was the word I needed in my Google searches. I found how to mark a task as a Milestone and use the pre-made Milestone filter. However, that still doesn't hide non-Milestone tasks the way I want it to. I haven't figured out how to make a true custom filter.

World Wide Publishing Service very slow to restart on IIS? Why?

- by StacMan

Every now and then, we look to restart our IIS server by restarting the "WWW Publishing Service". On most systems this would usually only take a minute or two, but this can often take up to 10 minutes to stop the server and restart. Does anyone know any way to work out what is taking so much time to stop the service? After reading up around the net I've learned this may be due to locked resources used by users and/or lower-level IIS cached items being recycled. But I cant seem to work out where I can validate if this is true on not. Also if anyone knows how to fix or speed this up, that would be excellent. We have a large codebase which contains over 280 aspx pages across the site. Our main domain contains about 100 aspx pages whilst the subdomains contain 15 or 20 each. Some specs: Code is written in C#; runs on .Net framework 2.0 Server Windows Web Server 2008 IIS7; DB running SQL Server 2008 Standard

Cannot resize OS X partition

- by joshhunt

I am trying to resize my existing Mac OS Extended partition on my Macbook to install Windows 7 (using steps similar to these), but when ever I go to apply the changes, I get this error: Partition failed Partition failed with the error: The partition cannot be resized. Try reducing the amount of change in the size of the partition. The total capacity of the hard drive in question is 260GB, with the entirety being taken up by the OS X boot partition. There is I am aiming to shrink that partition down to 60GB. How can I fix this problem? I have been reducing the amount of change by 10GB each attempt, but it still is not working. I assume the problem is that there is not a large amount of continuous space on the device. Is there some way to can do a manual defrag that would rectify this problem?

Error adding 4tb LUN (Raw Device Mapping) to ESX4 VM

- by Tom Gardiner

Hi guys, I'm trying to map an existing 4tb LUN from a Fibre Channel SAN, through to a VM in my ESX4 environment. It keeps telling me that the VMDK file size exceeds the the maximum size supported by the datastore. I've tried in Physical compatibility mode, and also both Virtual styles. I'm a little confused by this as we had the same LUN mapped through to another VM when we were running ESX3.5... I've also noticed that some of my other RAW mappings are generating extremely large VMDK files on the ESX servers. Does anyone know if this change in behaviour is intentional? And if so why? It doesn't seem to me that if the LUN is mapped directly to the VM that it's size should be relevant. We're running 4.0.0 build 236512, and 4.0.0 build 219382 and I've not had any success on either. Any insight or advice would be much appreciated! TG

How can you add two lines of text on a single line in Word 2010?

- by deodorant

Odd title, wasn't sure how to word it. Basically, I have two separate fonts I want to be on the same line, for resume purposes. My name is in a large font at the top, and I want my email and website address right-aligned directly beside it, one on top of the other. However, I want the email and website to combine to the same height as my name. Is this even possible with Word? Surely it is. Here is an awesome graphic of what I'm hoping for. Thanks! edit Seems new users can't post images. Link is here: http://i.stack.imgur.com/0gc3s.png

How to grow from single server setup

- by Jenkz

I'm looking for resources on how to grow our server setup. We currently have one dedicated server with Rackspace in the UK of the following spec: HPDL385_G2_PrevGen HP Single Dual Core Opteron 2214 (2.2Ghz) 4GB RAM 2x 10,000 SCSI Drives in RAID 1 Our traffic is up to 550,000 UVs per month. The site runs off a PHP and MySQL setup. The database gets an absolute hammering, we have many complex queries joining multilpe tables. We are using APC for PHP caching. I'm getting to the stage where I've done as much DB and query optimisation as I can and wonder what the next step should be...... I've looked at memcache, but I've got the impression that his requires a large amount of RAM and ideally a dedicated box.... So is the next step to have two boxes; one for database, one for Apache? Or is there a step I've overlooked. Our load is usually around the 2 mark, but right now it's up at 20!

LDAP search filter for Active Directory

- by Francesco De Vittori

Hello, I'm trying to look for users inside Active Directory through a LDAP query. Basically I'm searching for the user in this way: Search DN: dc=mydomain, dc=com Filter: (sAMAccountName=USER) where USER is replaced with the provided username. Now if USER is only the username without domain (for ex. "Joe") this works fine. However I receive them in the form (domain\username, for ex. "myDomain\Joe") and obviously the search fails. I see two ways: using a regex inside the Search Filter to discard the domain using a completely different search filter I'm no LDAP expert and I don't even know if it's possible to use regular expressions inside the search filters. Does anyone know if it's possible and how? P.S. I cannot pre-process the username to strip the domain. This cannot be changed, as it's all part of a large system.

Understanding this error: apr_socket_recv: Connection reset by peer (104)

- by matthewsteiner

So, if I do some benchmarking with apache benchmark (ab), and I use large numbers of requests. Then sometimes in the middle of a test I get this error. I don't even know what it means. So how can I fix it? Or is it just something that will happen if the server gets too many hits anyway? The problem is, if I run 10,000 hits, it'll all run perfectly. If I run it again, it'll get to 4000 and get the error: apr_socket_recv: Connection reset by peer (104) A little about my setup: I have nginx taking static requests and processing dynamic ones to apache. The file in question is served from cache by nginx, so I guess it's probably got to do with how nginx is handling the requests? Ideas?

We're running a fairly large site using nginx and PHP-FPM and we're getting a lot of errors as the site load is quite high.

Looking for FTP server that allows user management from database

- by hughesdan

I'm planning a server application that will handle files uploaded via FTP. The application must parse text documents that it receives and write them to a database (most likely a document-oriented database like Mongo). And the application must also relay all large binary files it receives to Amazon S3 for storage and hosting. I'd like to manage all aspects of the FTP server programmatically. For example, when a user registers via a web page the application should be able to create the user account in the database and provision a directory on the server for receiving files. I'm using a Linux server but am otherwise open to considering any programming language or framework. I experimented with VSFTPD but didn't like the way the application relies on config files and the creation of users and directories via the command line. Can someone please recommend what server framework I should consider? I'm a little biased toward solutions that leverage Javascript/Nodejs or Python. However, I'm open to anything that can run on a Linux box.

User's home drive permissions don't contain system or administrators on Windows Server 2008 R2

- by JohnyV

I have a user whose home drive has only that user in the permissions. No administrators, etc. I have tried to take ownership as a local administrator however I cant seem to apply settings to the child objects -- it still gives me a permission denied error. I know there are some handy CLI utils that can redo permissions. Any ideas? Or even a way to do it through Windows? The file server is a 2008 R2 server.

What can I do to give some more love and disk space to my database on Ubuntu?

- by Yaron Naveh

I'm new to linux. I've deployed a db to ubuntu server on amazon and found out I'm low on disk space. did df (see below) - and found out that I'm 89% capacity on one file system, but less on others. What does this mean? Do I have a few partitions and can now utilize others besides /dev/xvda1? Also /dev/xvdb seems large, is it safe to put the db in it and only use it? If so do I need to mount it or do something special? $> df -lah Filesystem Size Used Avail Use% Mounted on /dev/xvda1 8.0G 6.7G 914M 89% / proc 0 0 0 - /proc sysfs 0 0 0 - /sys none 0 0 0 - /sys/fs/fuse/connections none 0 0 0 - /sys/kernel/debug none 0 0 0 - /sys/kernel/security udev 3.7G 8.0K 3.7G 1% /dev devpts 0 0 0 - /dev/pts tmpfs 1.5G 164K 1.5G 1% /run none 5.0M 0 5.0M 0% /run/lock none 3.7G 0 3.7G 0% /run/shm /dev/xvdb 414G 199M 393G 1% /mnt

How can I exceed the 60% Memory Limit of IIS7

- by evilknot

Pardon if this is more stackoverflow vs. serverfault. It seems to be on the border. We have an application that caches a large amount of product data for an e-commerce application using ASP.NET caching. This is a dictionary object with 65K elements, and our calculations put the object's size at ~10GB. Problem: The amount of memory the object consumes seems to be far in excess of our 10GB calculation. BIGGEST CONCERN: We can't seem to use over 60% of the 32GB in the server. What we've tried so far: In machine.config/system.web (sf doesn't allow the tags, pardon the formatting): processModel autoConfig="true" memoryLimit="80" In web.config/system.web/caching/cache (sf doesn't allow the tags, pardon the formatting): privateBytesLimit = "20000000000" (and 0, the default of course) percentagePhysicalMemoryUsedLimit = "90" Environment: Windows 2008R2 x64 32GB RAM IIS7 Nothing seems to allow us to exceed the 60% value. See attached screenshot of taskman.

X locks up with konqueror on comics.com

- by retracile

If I browse to comics.com using konqueror under KDE on Fedora 11, X will, after a delay, lock up. The mouse will move, but no keyboard input is recognized, and the screen does not react to the mouse passing over objects on screen. I am able to ssh into the machine and issue shutdown -r now and have that work. The machine is a Dell XPS M1330 with Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c), and Fedora 11 is fully updated. Visiting the same site in Firefox does not cause a lockup. I am booting with nomodeset since it won't boot into X otherwise. I tried the other two accel options: EXA (still locks up) and XAA (X won't start). Any suggestions on how I can debug this? bugzilla

IIS FTP service - download timeouts and restarts getting the data twice

- by accel229

We have an IIS FTP site on a Windows Server 2003 x64 machine. Application Layer Gateway service is disabled (so http://support.microsoft.com/kb/931130 does not apply). Windows Firewall service is disabled as well. Connection timeout for the FTP site (there is only one) is set to 1,200 seconds = 20 minutes. An external client can connect to the site, list directory contents and download small files. When a client attempts to download a large file (eg, if the download continues for 3 minutes, which is still under 20 minutes, but relatively long), the server sends all data, then the connection times out, the client issues REST / RETR commands attempting to restart the download since after the last byte (which I believe should succeed and receive exactly 0 bytes), and the server behaves as if the client tried to restart after byte 0, that is, it sends the entire file all over. Any ideas on how to fix this?

Available Instance types for marketplace ami's

- by Christian

I based my autoscaling AMI's on the Turnkey Linux nginx AMI from the marketplace. I am now unable to select any of the newer generation instance types; for instance, my autoscaling uses m3.large type but I'd really like it to use the c3.xlarge type but every time I try to create a c3.xlarge instance with my AMI I get errors; The instance configuration for this AWS Marketplace product is not supported. My question is; Can I override this? I'm not using TKL support or any of their services, just the AMI. If I can't override it, do I have any other options besides creating a brand new AMI from scratch to use?

Clients not recognizing secondary LDAP groups?

- by Nick

I'm having an issue where users who are members of secondary groups in LDAP are not being recognized as members of that group by the client. In this case, user jdoe is not being recognized as a member of the projects group. On the client, getent group shows: projects:*:20001:1001,1002,1003,1004,1005,1006 and getent passwd shows: jdoe:x:1003:10003:John Doe:/home/jdoe:/bin/bash But if I log in to the client as jdoe, and run id, I get: uid=1003(jdoe) gid=10003(jdoe) groups=24(cdrom),25(floppy),29(audio),44(video),46(plugdev),10003(jdoe) It recognizes jdoe's primary group, and the secondary groups that are appended by the client to all LDAP users, but the LDAP secondary groups are not in the list. We can see that jdoe's id is in the projects group, so why is the projects group not showing when jdoe runs the id command? The group objects are basic posixGroup entries, with a memberUid attribute for each of its members. We are using OpenLDAP on Ubuntu 10.04 server and clients.

ADExplorer, how to search with "distinguishedName contains" condition?

I'm using ADExplorer 1.42 from Microsoft. I'm not very versed at this program so please kindly help me out with a search-related problem. Right click on a node(e.g., CN=NlscanStaff) and select Search Container... , with default search attributes, I can see all objects inside NlscanStaff listed as result. Note that there is a CN=CHJTEST object listed. Now, my question is, how to search for CHJTEST specifically? I tried search condition: Attribute : distinguishedName Relation : contains Value : CN=CHJTEST Click Add , then Search . But no result. Can someone tell me what's going wrong? Thanks.

Run Logstalgia on Remote Global Apache Log On a WHM System

- by macinjosh

I work for a small web development shop. We have a dedicated Linux server running WHM. For fun we want to run Logstalgia on a machine in our office. We'd really like it to display information about all the traffic on our server. Logstalgia use Apache's access logs to generate its visuals, the problem I have is that by default WHM does not have an access log for all sites combined. How can I safely configure our server to output a combined/global Apache access log in a place accessible by a non-root SSH user? I am also concerned that this file could get quite large so I think I'd also need to know how to have it automatically shed old information. To make things more interesting I'm a programmer not a sys admin so not everything is immediately obvious to me.

Using themes in visio

- by JohnW

I'm looking for a good reference on how to properly use themes in Visio. Here's been my experience so far: Create a flowchart diagram - nothing fancy, just all black & white. No formatting applied to any object. Select & apply a theme to the diagram. Despite the theme showing a set of matching colors, the diagram now has a single color applied to all objects. Right-click the object, format, fill, and pick a color from the set of matching theme colors. End up with an amalgamation of the original theme color I picked (blue) and the new color (green). With enough 'playing' with the object, I can get it to look OK, but it feels like I'm missing something, that it shouldn't be this hard to get a matching color. Any advice would be appreciated. :)

Asterisk, IAXModem & Hylafax how-tos?

- by Brian Postow

I'm trying to set up Asterisk and IAXModem to send faxes via T38 (Yes, I know I'm swatting a fly with a Buick...) However, since I'm trying to do something so small with a product so large, I'm having trouble finding samples or how-tos that show me how to set this up. I've got all three installed, and I THINK I have my IAXModem config correct. I'm pretty sure that I have Hylafax correct (I've used it with T38Modem) so, I need to know which of the Asterisk samples I need to use, and how to use them. I think I want to use some combination of iax.conf, iaxprov.conf, sip.conf and sip_notify.conf. But I'm not sure where to put them, or what to change... I'm sure that the answer is RTFM, but I'm not sure WHICH M, or where in it to R... thanks.
