• Direct DB to Web Server connection

  - by Joel Coel

  I have a database server sitting right underneath a virtual machine host server in the rack, and this vm host is primarily responsible for servers hosting a couple different web sites and app servers that all talk to databases on the other server. Right now both servers are connected to the same switch, and I'm pretty happy with the pathing. However, both servers also have an unused network port. I wondering about the potential benefits of using a short crossover or normal+auto mdix network cable to connect these two servers together directly. Is this a good idea, or would I be doing something that won't show much benefit and is just likely to trip up a future admin who's not looking for this? The biggest weakness I can see right now is that this would likely require a code change for each vm app to point to the new IP of the database server on this private little network, and if I have a problem with the virtual machine host and have to spin up it's guests elsewhere while I fix it I'll have to change this back before things will work.

• Can I force NFS automounts to use NFSv3?

  - by Steve

  I have a linux server that is exporting NFSv4 as well as NFSv3. I have a Fedora14 client that is defaulting to NFSv4 when automounting NFS shares off of the linux server, and it seems to be causing some problems. All my other linux clients on the network are mounting via NFSv3 without issue, so is there a way I can tell automount to mount the share via v3? I am pulling my automount maps via LDAP, with an entry in my /etc/auto.master file like so: +auto_master, so I assume it's a bit different than listing options with a regular automount map? (.i.e. /home --nfsvers=3 fileserver:/DATA)

• Create a form as a worksheet in Excel that adds records to another worksheet

  - by Holden Fenner

  I am trying to create a form in Excel for vehicle requests. What I want to happen is to create one worksheet that is a recreation of the current paper form, but have a clickable button that will enter all the data for the vehicle request as a record on a second worksheet. Conversely, if you know the record number, I want the form to auto-flll the information from that record number. I have the second part figured out, that should be a simple HLOOKUP, but I don't know how to generate the clickable button. Will I need to use scripting for this, or is there an pre-built way of doing this? (As an aside, I know there are other and better ways of accomplishing database work, but the nature of my work makes Excel the best choice)

• Create 301 Redirection in Amazon Route 53 for Wildcard Subdomains

  - by Eric Yin

  My domain name hosted on Route 53 DNS. Amazon has a guide to do 301 redirection for www. To naked domain by point www. version to a S3 static website with 301 setted up. My question is, how can I have *.domain.com all have 301 redirec to naked domain name. I guess either: Some way to get all wildcard subdomains end up into one S3 bucket, how? Or: Use CloudFront on the www. version S3 site and put wildcard subdomains on the CloudFront, but how? Or: There's some hidden settings just lies on Router 53, then where? Or: use EC2, better not suggest me this, too costing for this task. Please advice.

• If I use openvpn, can vpn servers monitor my usernames/passwords?

  - by Duff

  Openvpn uses a type of encryption similar to ssl. This seems to suggest that even if I choose an incredibly shady VPN server, then my content will be secure. That is, the VPN server will be able to monitor what websites I patronize, but not the actual data I transfer. That said, I am not an expert at this type of thing. I wanted, therefore, to make sure that I understand correctly. Is it true that if I use openvpn that my username/passwords are secure, even if the VPN is untrustworthy? If not, why? (And how, if at all, can it be fixed?) Examples of things that I don't know much about that may (or may not! I honestly don't know much about this.) be related to my question are: DNS leakage, IPv6, tracking cookies, browser plugins and websites that don't support https.

• How to choose size for a cloud server (rackspace)

  - by Emil

  We're going to test the rackspace cloud next week to see how it's working with our web app. It's a LAMP environment with a lot of MySQL databases. How do I choose the "right" server size? On Rackspace I can choose slices with the memory of 256, 512, 1024, 2048, 4096 etc. Right now we don't have a lot of traffic (approx. 1000 visitors/day) but I thought the whole "cloud" idea was to not be limited and auto scale. Update: What I'm looking for is now a specification of what I need. I know it's too complex. I'm looking for examples, case studies etc. It would be interesting to hear something like "Yes we're serving 10 000 daily requests without spikes on a LAMP stack with only one slice on with 2 GB RAM".

• Multiple Memcached server /etc/init.d startup script that works ?

  - by p4guru

  I install memcached server via source and can get standard start up script installed for 1 memcached server instance, but trying several scripts via google, can't find one that works to manager auto start up on boot for multiple memcached server instances. I've tried both these scripts and both don't work, service memcached start just returns to command prompt with no memcached server instances started lullabot.com/articles/installing-memcached-redhat-or-centos addmoremem.blogspot.com/2010/09/running-multiple-instances-of-memcached.html However this bash script works but doesn't start up memcached instances at start up though ? #!/bin/sh case "$1" in start) /usr/local/bin/memcached -d -m 16 -p 11211 -u nobody /usr/local/bin/memcached -d -m 16 -p 11212 -u nobody ;; stop) killall memcached ;; esac OS: Centos 5.5 64bit Memcached = v1.4.5 Memcache = v2.2.5 Anyone can point me to a working /etc/init.d/ startup script to manage multiple memcached servers ?

• Get sessions' remote IP from Teamviewer log file

  - by etuardu

  I'd like to know who has logged in to my machine and when. I have two TeamViewer log files: Connections_incoming.txt and TeamViewer7_Logfile.log. The first one is quite plain and lists, as its name says, the incoming connections to the machine, reporting the local name of the remote host, login time, logout time, and some ids. e.g.: 173274362 MYLAPTOP 20-02-2012 17:32:16 20-02-2012 17:50:42 Master RemoteControl {C5AAE483-ED0B-54B8-9235-7AE597CAD342} This is almost all what I need, but unfortunately no remote IP address is reported here, so I checked for IPs in TeamViewer7_Logfile.log but it is really messy. It indeed contains some IP addresses but I can't understand which one is bound with the items in the first log file. Is there a way to interpolate the two logs to get what I need? Should I search the second file for some particular text? What do you suggest?

• Hosts that allow email marketing?

  - by Ghost1227

  I work for a company that heavily relies on email marketing to make money and we're running into a problem. We are trying to spin up a new email server and are finding it difficult to find a hosting company that doesn't explicitly disallow any form of mass mailing, legitimate or otherwise! Our lists are all opt-in, so the legitimacy issues aren't a problem, and we comply 100% with CAN-SPAM laws, but that doesn't seem to matter to hosting companies. Does anyone else have experience in this market? Can anyone suggest hosting companies that either support ESPs or are at least mass-mailing friendly? I've done lookups on most of the big players in the field and it seems that all of them are hosting their own equipment, which is currently cost prohibitive for us.

• Remove Excel data link in Visio Drawing

  - by Ddono25

  I am creating a server topology for one of our SharePoint farms and thought it would be easy to just link the Excel spreadsheet with our server information to the Visio drawing to auto-populate some things. It didn't work out that well, but the drawing is finished without it now. I cannot remove the link between the Excel spreadsheet and the Visio diagram. Whenever the drawing is opened the linked excel server list opens in a pane at the very bottom of the window. How would I eliminate the data link? Or just the spreadsheet from view when being opened?

• Correct password for ssh key rejected when ssh-d into machine

  - by user20342

  When I am logged into my machine directly, I can do all git operations, and when prompted for a password, the password is accepted. When I ssh into the same box and run git operations on the same repos, the password is rejected. Relevant section of .ssh/config looks like this: # Generic settings Host * ServerAliveInterval 600 ControlPath /tmp/ssh-%r@%h:%p ControlMaster auto KeepAlive yes IdentityFile ~/.ssh/id_rsa.pub Transaction looks like this when I login when I ssh into my box: {12-12-03 9:41}hbrown-wks2:~/workspace/spt/project@master??? hbrown% git pull Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': Enter passphrase for key '/home/hbrown/.ssh/id_rsa.pub': Permission denied (publickey). fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. Using bash does not appear to make a difference (i.e. ssh-agent /bin/bash). This is a recent development, but I can't cite the change that caused it.

• How secure is Windows IPSec VPN?

  - by sergeb

  I know the answer is, depends on how you configure it... But bare with me - our IPSec Site-to-Site VPN is configured by one of the most trusted hosting companies. One of our clients expressed concerns that "Windows Server 2008 Server IPSEC is not ICSA certified and lacks some of the common features for maintaining VPN stability" (they refer to the lack of "auto keep live" feature). They also are saying that "Windows platforms are not recommended as VPN endpoints due to security concerns and this is one reason that the ICSA testing labs will not certify it as a valid IPSEC solution" (I couldn't find a proof to this one) Are there any whitepapers or references that can prove the security of Windows IPSec implementation? Thanks!

• Mount /tmp in /mnt on EC2

  - by Claudio Poli

  I was wondering what is the best way to mount the /tmp endpoint in the ephemeral storage /mnt on an EC2 instance and give the ubuntu user default write permissions. Some suggest editing /etc/rc.local this way: mkdir -p /mnt/tmp && mount --bind -o nobootwait /mnt/tmp /tmp However that doesn't work for me. I tried editing the fstab: /dev/xvdb /tmp auto defaults,nobootwait,comment=cloudconfig 0 2 and giving it a umask=0777, however it doesn't work because of cloudconfig. I'm using Ubuntu 12.04.

• Migrate reports from MS Access to OOo Base

  - by John Gardeniers

  I'm currently looking at upgrading our office machines from Office XP to Office 2010. For most users the standard edition is fine but just a few of us use Access. There are only a couple of standalone Access databases but the program is used fairly extensively (mostly by myself) as a front end to MySQL. As the cost different between standard and pro versions of Office 2010 is about $170 (AUD) I'm looking at possible alternatives to Access. I'm no huge fan of Open Office but could be convinced to use it if I can find a way to migrate the many reports we currently have in Access. The data is not a problem. So far I've found nothing to suggest this is even possible/practical but perhaps someone here knows otherwise. I'm also open to suggestions for other alternatives to Access but it must be able to produce flexible reports easily. That is the one real strength of Access in my view. Because of its subjective nature I'm making this community wiki.

• How to enable forward search in Adobe Reader from TeXnicCenter?

  - by Sergiy Byelozyorov

  I am creating a LaTeX document in TeXnicCenter with LaTeX = PDF profile. There is a feature which allows to open and scroll auto-generated PDF to the paragraph that is under the cursor in TeXnicCenter. This works with Sumatra PDF and the feature is called "Forward search" in Profile settings, "Viewer" tab. I would like to have the same feature with Adobe Reader. Is this possible at all? Do I have to use "command line" or "DDE command" setting? What do I have to fill in "Command", "Server", "Topic" fields in the Profile settings?

• Can somebody help me install this jBPM based workflow management suite?

  - by Eternal Saint

  1.Its a book Workflow Interface software available at sourceforge http://bookworkflowint.sourceforge.net/ Any instructions on installing and configuring it would be great especially in windows, however I can try Linux specific ones as well. I could not find any installation instructions. I posted this in stackoverflow by mistake and was directed here. 2.Can you guys suggest any good scanning/digitization workflow software (document imaging) that I can adopt to my scanner software? Infact even a simple one would do may be based on hotfolders. I just want to be able to track the uniqueid/barcode of the scanned book, its status so that its not scanned again. It books or manuscripts could be in millions page count. I thought of using some kind of generic bug tracking tool, just track a few fields, dont know if its the right choice Thank you very much

• Configuring Mail Relay

  - by ServerChecker

  I'm running Ubuntu Server 9.10 with Postfix and Webmin. I have created virtual hosts for 3 domains following this serverfault.com answer. But the mail isn't relaying out to the world. I have 3 domains tied into my DNS in webmin, as well as inside DNS clicked Mail Server and followed that instruction using this article on the web. The domains and the web servers work just fine. I also have FTP working just fine. So, the remaining problem I have is mail. Can't forward mail out to a Gmail account for some reason. Note I'm just trying to do the "easy version" of Postfix config and if your answer is in Webmin-ease, that would help me. However, I can edit a text file if you suggest.

• Program can't start because GX6050R.dll is missing

  - by Robert P.

  I'm trying to install a program on a Windows 7 machine, but in the end of the installation process, when I press "Finish", I get an error message saying: Actrix.exe - System Error The program can't start because GX6050R.dll is missing from your computer. Try reinstalling the program to fix this problem. I have tried reinstalling the program, restarting the computer (before reinstalling) etc., but I can't get this to work. The sites I find when I Google this suggest I download some "Error repair tool" (not happening). Any clues as to how I can fix this?

• How to generate the right password format for Apache2 authentication in use with DBD and MySQL 5.1?

  - by Walkman

  I want to authenticate users for a folder from a MySQL 5.1 database with AuthType Basic. The passwords are stored in plain text (they are not really passwords, so doesn't matter). The password format for apache however only allows for SHA1, MD5 on Linux systems as described here. How could I generate the right format with an SQL query ? Seems like apache format is a binary format with a lenght of 20, but the mysql SHA1 function return 40 long. My SQL query is something like this: SELECT CONCAT('{SHA}', BASE64_ENCODE(SHA1(access_key))) FROM user_access_keys INNER JOIN users ON user_access_keys.user_id = users.id WHERE name = %s where base64_encode is a stored function (Mysql 5.1 doesn't have TO_BASE64 yet). This query returns a 61 byte BLOB which is not the same format that apache uses. How could I generate the same format ? You can suggest other method for this too. The point is that I want to authenticate users from a MySQL5.1 database using plain text as password.

• Control truetype font tracking in fontforge

  - by ??O?????

  Hello. I'm designing a font intended to be used mainly as a subtitle font. It's a sans-serif font not unlike Helvetica. The em size is 2000 (I know it "should" be 2048 for a truetype font), the ascent/descent are 1600/400. Most glyphs don't go higher than 1450 though, with the exception of accented Latin characters. There lies the issue: when my font includes accented Latin characters, the tracking (line -of-text intradistance, but correct me if I got the term "tracking" wrong) skyrockets. I can't seem to find a way to control that. As my intended design goes, I don't mind if I have a descender (e.g. "g") above and an accented capital Latin letter below and they almost touch. It's something that does not happen very often, anyway. How can I control tracking? It seems it's auto-calculated.

• Outlook 2010 exchange setup prompts for [email protected] rather than [email protected]

  - by Force Flow

  We use a hosted exchange service. When users want to set up Outlook 2010 to access their account, they open Outlook and run through the configuration steps. Autodiscover is enabled, and in the user's active directory profile, their email address is in the email field. However, when the configuration process reaches a point where they are prompted for their email account's username and password, their active directory username is filled in by default instead of their email address. Is there a way to fix that? Users get confused and try to enter their email password over and over again and wonder why it doesn't work (and completely miss/ignore the "use another account" button even though they have instructions right in front of them). I'm also using the Office 2010 ADM's in group policy, but I haven't yet seen an option to specify what gets auto-populated in that windows security prompt.

• Way to update / refresh / reschedule project plan after adding a vacation / changing calendar

  - by CodeCanvas

  I had created a project plan using MS-Project 2010 (not server). I had set the task schedule mode to "Auto Scheduled" and entered the necessary tasks. Since it is a single person project I also added one person to the Resource of the file and assigned that resource to all the tasks and leveled the project. After the plan was put in and tasks were leveled I figured the calendar was not correctly set (in UAE the weekend is Friday and Saturday instead of Saturday and Sunday). So, I updated the default calendar (Standard) of the project by going to Project-Change Working Time-Work Weeks and changed them as needed. But after doing this, the tasks are still scheduled over Friday and Saturday even though I have marked them as nonworking days in the standard calendar. I tried the following for the tasks to refresh, but I was not successful: Updated all tasks to use the "Standard" calendar in the project Selected option so that tasks do not ignore resource calendars Added a constraint "As Soon As Possible" Executed "Level All" Any help on solving this issue would be much appreciated, thanks in advance.

• How to Pre-Configure Shared Laptops' Microsoft Outlook 2010 Accounts to Connect to Exchange Server 2007 SP3?

  - by schultkl

  Our IT environment provides 10 shared, Microsoft Windows 7 laptops for an office staff of several hundred people. After checking-out and logging into a laptop with an Active Directory domain account, office staff frequently run Microsoft Outlook 2010. However, the first time office staff do this, Microsoft Outlook 2010 prompts the user to create and configure their local account. This takes just several clicks, as Microsoft Outlook 2010 auto-detects the office staff member's Microsoft Exchange Server 2007 (SP3) account. The problem is: all office staff have to do this on each new laptop they use. Until they do so, some functionality does not work (for example, Microsoft Word 2010 Save & Send fails with error "There was a problem creating the message"). How might our IT department "pre-configure" the shared laptops so office staff can simply log-in and use Microsoft Outlook 2010 functionality without the need to configure a local account?

• SAN shows as unallocated in Windows Server

  - by Gareth Ferneyhough

  Hello. We have a SAN drive that shows as unallocated in Windows Server 2008. I believe it is a raid 10 with 4+ disks. The disks are in good health. I think a server that we rebuilt tried to connect to the drive and re-initialized them, or re-wrote the partition table. (excuse my poor terminology). We ran TestDisk on the drive and it shows no partitions, so now we are doing a quick search (which is not so quick). Can anyone else suggest anything? Thanks, Gareth

• How to add command line arguments to command line arguments in Windows shortcut?

  - by Pawin

  I know I can add a command line argument/option to a shortcut this way; for example: "C:\Program Files\Internet Explorer\iexplore.exe" www.a.com So IE will connect to a.com when it starts up. What I would like to do is to get IE connecting to a.com when I call it through another program like the following: C:\Windows\SysWOW64\ForceBindIP.exe 192.168.1.151 "C:\Program Files\Internet Explorer\iexplore.exe" www.a.com This does not work. IE starts up but doesn't go to a.com. It seems like the argument is either ignored or is understood as an argument of ForceBindIP instead (I'm not sure). What I am trying to do is to create 2 IE shortcuts such each of them binds one IE window to one NIC and one particular website. So adding the www.a.com etc in its startup list won't help. OS is Windows 8. Apologize if this has been asked and answered before. Please suggest keywords for searching if that's the case.
