• Configure Postfix to send/relay emails Gmail (smtp.gmail.com) via port 587

  - by tom smith

  Hi. Using Centos 5.4, with Postfix. I can do a mail [email protected] subject: blah test . Cc: and the msg gets sent to gmail, but it resides in the spam folder, which is to be expected. My goal is to be able to generate email msgs, and to have them appear in the regular Inbox! As I understand Postfix/Gmail, it's possible to configure Postfix to send/relay mail via the authenticated/valid user using port 587, which would no longer have the mail be seen as spam. I've tried a number of parameters based on different sites/articles from the 'net, with no luck. Some of the articles, actually seem to conflict with other articles! I've also looked over the stacflow postings on this, but i'm still missing something... Also talked to a few people on IRC (Centos/Postfix) and still have questions.. So, i'm turning to Serverfault, once again! If there's someone who's managed to accomplish this, would you mind posting your main.cf, sasl-passwd, and any other conf files that you use to get this working! If I can review your config files, I can hopefully see where I've screwed up, and figure out how to correct the issue. Thanks for reading this, and any help/pointers you provide! ps, If there is a stackflow posting that speaks to this that I may have missed, feel free to point it out to me! -tom

• Helicon ISAPI Rewrite Proxy 500 Internal Server Error

  - by Rob Stevenson-Leggett

  Hi, I have a website running at www.domain.com. The client now wants the website to appear to be running under www.otherdomain.com/whatson/brand/ Since the website is umbraco it won't run under a subfolder. I wanted to use ISAPI rewrite to proxy requests to www.domain.com using the following rule in a .htaccess at www.otherdomain.com/whatson/brand/ RewriteRule ^(.*)$ http://www.domain.com/$1 [P,L] However, when I apply this I get an ugly 500 Internal Server Error. There's nothing in the event log. So I turned on ISAPI logging and can see the following 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) init rewrite engine with requested uri /whatson/brand/home.aspx Then it testing all the other rewrite rules on the server. Then this 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (1) Htaccess process request w:\websites\otherdomain.com\docs2\whatson\brand\.htaccess 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (3) applying pattern '^(.*)$' to uri 'home.aspx' 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) forcing proxy-throughput with http://www.domain.com/home.aspx 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (1) go-ahead with proxy request http://www.domain.com/home.aspx [OK] 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) rewrite 'home.aspx' -> '/whatson/brand/home.aspxx.rwhlp?p=0' 111.111.111.111 111.111.111.111 Tue, 12-Jan-2010 13:05:24 GMT [www.otherdomain.com/sid#2045305275][rid#26337200/initial] (2) internal redirect with /whatson/brand/home.aspxx.rwhlp?p=0 [INTERNAL REDIRECT] So it appears to work according to the logs, but I'm not seeing the page come through.. It's worth noting that www.domain.com and www.otherdomain.com are on the same box. LogLevel is 3 and RewriteLogLevel is 3 (I've tried with 9 and debug but there is too much traffic going through the other sites on the box) Any ideas?

• How do I upgrade PHP on CentOS and Kloxo?

  - by Emerson

  I need to upgrade PHP so that I can upgrade joomla on my dedicated server. I have: kloxo 6.1.6 php-5.2.17-1 Linux CentOS-55-64-minimal 2.6.18-194.32.1.el5 x86_64 x86_64 x86_64 GNU/Linux I searched everywhere and I could only find that PHP 5.3 isn't compatible with zend. I would like to upgrade to 5.2.4, which is the minimum for joomla 1.6 and 1.7. I tried to run: yum update php.x86_64 Which is the PHP package installed, but it didn't work. This is a production server with quite a few users across many sites, so I wanted to do it as safely as possible. Is it safe to run "yum update"? It showed me 6 packages to install and 125 packages to update, including a kernel. Is that safe? I haven't touched kloxo's yum repositories. Update: I just successfully ran "yum update". Now I think I need to know how to add a new repository that has the 5.2.4 and how to update to that specific version. Any ideas?

• Exclude specific domains from Apache2 serverAlias while using a catch all *(wildcard) alias

  - by Victor S

  I have a web application that needs to support custom domains, in that regard I have set-up the following name based virtual server: <VirtualHost *:80> ServerName example.com ServerAlias * *.example.com www.example.com example.com RailsEnv production RackEnv production DocumentRoot /srv/www/example/current/public <Directory /srv/www/example/current/public> AllowOverride all Options -MultiViews FollowSymLinks </Directory> ErrorLog /srv/www/example/log/error.log TransferLog /srv/www/example/log/access.log </VirtualHost> Notice the * as the server alias? that catches all the domains on that server. However, I have other sites on this server which I want to be excluded from this list. It is more economical for me to have a list of excluded domains than manually set every domain a user may register with at this service as a serverAlias... Perhaps this is not the best way to go, but I'm looking for help, in the best (relatively simple) way to set up a web-app that may catch any domains, while allowing other specific domains to be routed to different apps. Thanks!

• Nginx case-insensitive reverse proxy rewrites

  - by BrianM

  I'm looking to setup an nginx reverse proxy to make some upcoming server moves and load balanced implementations much easier within our apps. Since our servers are all IIS case sensitivity hasn't been an issue, but now with nginx it's becoming one for me. I am simply looking to do a rewrite regardless of case. Infrastructure notes: All backend servers are IIS Most services are WCF services I am trying to simplify the URLs so I can move services around as we continue to build out I can't set my location to case insensitive due to the following error: nginx: [emerg] "proxy_pass" cannot have URI part in location given by regular expression, or inside named location, or inside "if" statement, or inside "limit_except" block in /etc/nginx/sites-enabled/test.conf:101 The main part of my conf file where I am trying to handle the rewrite is as follows location /svc_test { proxy_set_header x-real-ip $remote_addr; proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for; proxy_set_header host $http_host; proxy_pass http://backend/serviceSite/WFCService.svc; } location ~* /test { rewrite ^/(.*)/$ /svc_test/$1 last; } It's the /test location that I can't get figured out. If I call http://nginxserver/svc_test/help I get the WCF help page to display correctly and I can make all available REST calls. This HAS to be a boneheaded regex issue on my part, but I have tried several variations and all I can get are 404 or 500 errors from nginx. This is NOT rocket science so can someone point me in the right direction so I can look like an idiot and just move on?

• PHP-FPM and APC for shared hosting?

  - by Tiffany Walker

  We are looking into finding a way to get APC to only create one cache per account / site. This can be done with Fastcgi (last update 2006…) but with Fastcgid APC will have to create multiple caches for multiple processes run by the same account. To get around this problem, we have been looking into PHP-FPM PHP process manager allows multiple PHP processes to share a single APC cache. But from what I have read (I hope I'm wrong) , even if you create a pool per process, all sites accross all pools will share the same APC cache. This brings us back to the same problem as with shared Memcached: it's not secure ! On php-fpm's site I read that you can chroot php-fpm pools and define a specific UID and GID per pool… if this is the case then shouldn't APC have to use this user and not have access to other pools cache ? An article here (in 2011) suggests that you would need to run one process per pool creating multiple launchers on different ports and different config files with one pool per config file : http://groups.drupal.org/node/198168 Is this still neceessary ? If so what would be the impact of running say 800 processes of php-fpm ? Would it be mainly memory ? If so how can I work out what the memory impact would be ? I guess that it would be better to run 800 times php-fpm then to have accounts creating multiple APC caches for a single site ? If on average an account creates a 50MB cache and creates 3 caches per account that makes 150Mb per account which makes 120GB… However if each account uses on average only 50Mb that would make 40GB We will have at least 128GB of ram on our next server so 40GB is acceptable if running 800 x PHP-FPM does not create an overhead of more than 20GB ! What do you think is PHP-FPM the best way to go to provide secure APC cache on shared hosting with a server that has a decent amount of memory ? Or should I be looking at another system ? Thanks !

• Trying to reconcile global ip address and Vhosts

  - by puk

  I have been using my local machine as a web server for a while, and I have several websites set up locally on my machine, all with similar Vhost files like the one seen here /etc/apache2/sites-available/john.smith.com: <VirtualHost *:80> RewriteEngine on RewriteOptions Inherit ServerAdmin [email protected] ServerName john.smith.com ServerAlias www.john.smith.com DocumentRoot /home/john/smith # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg. LogLevel warn LogFormat "%v %l %u %t \"%r\" %>s %b" comonvhost CustomLog /var/log/apache2/access.log comonvhost </VirtualHost> then I set up the /etc/hosts file like so for every Vhost: 192.168.1.100 www.john.smith.com john.smith.com 192.168.1.100 www.jane.smith.com jane.smith.com 192.168.1.100 www.joe.smith.com joe.smith.com 192.168.1.100 www.jimbob.smith.com jimbob.smith.com Now I am hosting my friend's website until he gets a permanent domain. I have port forwarding set up to redirect port 80 to my machine, but I don't understand how the global ip fits into all of this. Do I for example use the following web site addresses (assume global ip is 12.34.56.789): 12.34.56.789.john.smith 12.34.56.789.jane.smith 12.34.56.789.joe.smith 12.34.56.789.jimbob.smith

• DirectAccess Server firewall rules blocking ports

  - by StormPooper

  I have configured DirectAccess on my Server 2012 Essentials box and most of it works great - I can remotely access the server via RDP and the default IIS website on port 80. However, I can't access anything that uses other ports. For this example, the Team Foundation Server website. The only way to access it is by accessing http://localhost:8080/tfs on the server directly - even when using http://servername:8080/tfs or http://192.168.1.100:8080/tfs won't work. I've tried adding the ports to the NAT exceptions using Set-NetNatTransitionConfiguration –IPv4AddressPortPool and while that has allowed some ports used internally (Deluge, for example) it hasn't allowed me access to the URL. I think I've narrowed it down to the "DirectAccess Server Settings" Group Policy that is created when configuring DirectAccess. When I disable the link for this GPO, the TFS site works again, but the default IIS site stops working (but RDP still works). I already have rules in the firewall on the server for TFS and before enabling this Group Policy (so before configuring DirectAccess) I could access both sites. Does anybody have any suggestions for things I can change to allow access to both? I've uploaded the full GPO report and my Remote Access Configuration Summary for more details.

• Using %v in Apache LogFormat definition matches ServerName instead of specific vhost requested

  - by Graeme Donaldson

  We have an application which uses a DNS wildcard, i.e. *.app.example.com. We're using Apache 2.2 on Ubuntu Hardy. The relevant parts of the Apache config are as follows. In /etc/apache2/httpd.conf: LogFormat "%v %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vlog In /etc/apache2/sites-enabled/app.example.com: ServerName app.example.com ServerAlias *.app.example.com ... CustomLog "|/usr/sbin/vlogger -s access.log /var/log/apache2/vlogger" vlog Clients access this application using their own URL, e.g. company1.app.example.com, company2.app.example.com, etc. Previously, the %v in the LogFormat directive would match the hostname of the client request, and we'd get several subdirectories under /var/log/apache2/vlogger corresponding to the various client URLs in use. Now, %v appears to be matching the ServerName value, so we only get one log under /var/log/apache2/vlogger/app.example.com. This breaks our logfile analysis because the log file has no indication of which client the log relates to. I can fix this easily by changing the LogFormat to this: LogFormat "%{Host}i %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" vlog This will use the HTTP Host: header to tell vlogger which subdirectory to create the logs in and everything will be fine. The only concern I have is that this has worked in the past and I can't find any indication that this has changed recently. Is anyone else using a similar config, i.e. wildcard + vlogger and using %v? Is it working fine?

• IIS7 bulk bindings in vbscript , how to remove a binding

  - by minus4

  I have a script to manage adding over a thousand domains to a single site bindings, this has gone fine, but now client wants about 20 of them removed, Microsoft programmers don't think it would be nice to sort the bindings alphabetically, so does anyone know the code to remove the domains ( array list ) in bulk please. this is what i am using: Set adminManager = createObject("Microsoft.ApplicationHost.WritableAdminManager") adminManager.CommitPath = "MACHINE/WEBROOT/APPHOST" Set sitesSection = adminManager.GetAdminSection("system.applicationHost/sites", "MACHINE/WEBROOT/APPHOST") Set sitesCollection = sitesSection.Collection siteElementPos = FindElement(sitesCollection, "site", Array("name", "microsites")) If siteElementPos = -1 Then WScript.Echo "Element not found!" WScript.Quit End If on error resume next Set siteElement = sitesCollection.Item(siteElementPos) Set bindingsCollection = siteElement.ChildElements.Item("bindings").Collection Dim arrFileNames : arrFileNames = Array("list of domains") Dim objDict : Set objDict = CreateObject("Scripting.Dictionary") Dim strFileName, strTemp For Each strFileName In arrFileNames Set bindingElement = bindingsCollection.CreateNewElement("binding") bindingElement.Properties.Item("protocol").Value = "http" bindingElement.Properties.Item("bindingInformation").Value = "192.168.100.19:80:" & strFileName bindingsCollection.AddElement(bindingElement) Next adminManager.CommitChanges() WScript.Echo "Job Completed" WScript.Quit Function FindElement(collection, elementTagName, valuesToMatch) For i = 0 To CInt(collection.Count) - 1 Set element = collection.Item(i) If element.Name = elementTagName Then matches = True For iVal = 0 To UBound(valuesToMatch) Step 2 Set property = element.GetPropertyByName(valuesToMatch(iVal)) value = property.Value If Not IsNull(value) Then value = CStr(value) End If If Not value = CStr(valuesToMatch(iVal + 1)) Then matches = False Exit For End If Next If matches Then Exit For End If End If Next If matches Then FindElement = i Else FindElement = -1 End If End Function so as you can see it is easy to add, but i can find no code or manual or instructions for the removal. i cant seem to run appcmd either. at first i tried creating a batch file using the appcmd but this never worked, saying appcmd can not be found. thanks

• IBM HS23 Blade Server (7875) onboard NIC driver for linux

  - by Igor Spivak

  I work with IBM HS23 Blade Server (7875). It's onboard NIC adapter is: Emulex OCl11104-F-X Virtual Fabric Adapter 2-port 10GB and 2-port 1GB LOM . I'm tryed to the following Linux OS with the server: 2.6.32-22-generic-pae #36-Ubuntu SMP. and discovered my OS has not proper Network drive installed (for the NIC adapter described above). After investigation I made, I discovered that the driver I need is "be2net" placed in "net" directory of the linux under the folder "be2net". I managed to download this driver with the latest package for my kernel. Driver info ("modinfo be2net" result) is as follows: --------------------------------------------------------------------------------------- filename: /lib/modules/2.6.32-22-generic-pae/kernel/drivers/net/benet/be2net.ko license: GPL author: ServerEngines Corporation description: ServerEngines BladeEngine2 10Gbps NICDriver 2.101.205 version: 2.101.205 srcversion: 199ADD251CB874C3727CC47 alias: pci:v000019A2d00000710sv*sd*bc*sc*i* alias: pci:v000019A2d00000701sv*sd*bc*sc*i* alias: pci:v000019A2d00000700sv*sd*bc*sc*i* alias: pci:v000019A2d00000221sv*sd*bc*sc*i* alias: pci:v000019A2d00000211sv*sd*bc*sc*i* depends: vermagic: 2.6.32-22-generic-pae SMP mod_unload modversions 586TSC parm: rx_frag_size:Size of a fragment that holds rcvd data.

I checked the same server with another Linux version (Red-Had 5.5.1.0) and the NICs worked properly, so seems there is no problem in HW. Also, on IBM or Emulex offical sites I managed to find drivers only for Red-Had and SUSE versions.

• File transfer problems through VPN when Cisco IPS is enabled

  - by Richard West

  We have a Cisco ASA 5510 firewall with the IPS module installed. We have a customer that we must connect to via VPN to their network to exchange files via FTP. We use the Cisco VPN client (version 5.0.01.0600) on our local workstations, which are behind the firewall and subject to the IPS. The VPN client is successful in connecting to the remote site. However when we start the FTP file transfer we are able to upload only 150K to 200K of data, then everything stops. A minute later the VPN session is dropped. I think I have isolated this to an IPS issue by temporarily disabling the Service Policy on the ASA for the IPS with the following command: access-list IPS line 1 extended permit ip 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 inactive After this command was issued I then established the VPN to the remote site and was successful in transferring the entire file. While still connected to the VPN and FTP session I issued the command to enable the IPS: access-list IPS line 1 extended permit ip 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0 The file transfer was tried again and was once again successful so I closed the FTP session and reopened it, while keeping the same VPN session open. This file transfer was also successful. This told me that nothing with the FTP programs was being filtered or causing the problem. Furthermore, we use FTP to exchange files with many sites everyday without issue. I then disconnected the original VPN session, which was established when the access-list was inactive, and reconnected the VPN session, now with the access-list active. After starting the FTP transfer the file stopped after 150K. To me this seems like the IPS is blocking, or somehow interfering with the initial VPN setup to the remote site. This only started happening last week after the latest IPS signature updates were applied (sig version 407.0). Our previous sig version was 95 days old becuase the system was not auto updating itself. Any ideas on what could be causing this problem?

• ASP.Net application can no longer write to DB after having run out of disk space

  - by remi.despres-smyth

  I'm a software developer troubleshooting a sticky problem on a client's production server, and I've got a bit of a problem. They have a virtual server running Windows Server 2008, SQL Server 2008 R1 and IIS7. It was provisioned with two partitions: one that has the OS (~15 Gig), and the other has IIS' web sites (another ~15 Gig). My application that's running this server has been running perfectly well, up until about an hour ago, when it started throwing System.IO.IOException: "There is not enough space on disk". As soon as my client notified me, I cleared up some space on C:\, emptied the recycle bin, and restarted SQL Server and IIS. The web server came back up and the application was running, but it no longer saves information to the database. No error message is coming up, the application can get information out of the DB, but it can no longer save data back to it. I rebooted the server, to no effect. I spoke with a sys admin at the hosting company, and he says SQL Server appears to have come up fine and the database is not in read-only mode. I confirmed that, as I can add records to tables from SQL Server Management Studio. I looked at the event log immediately after trying to save an edited record in the app, and no new events appear in there that I can tell. I'm assuming this is related to having run out of space, as it was all working fine prior to that, but I'm at a bit of a loss as to what exactly needs a kick in the pants to get going again. Can anyone help me out? What the heck is going on here?

• Reverse Proxies and AJAX

  - by osij2is

  A client of ours is using IBM/Tivoli WebSEAL, a reverse-proxy server for some of their internal users. Our web application (ASP.NET 2.0) and is a fairly straightforward web/database application. Currently, our client users that are going through the WebSEAL proxy are having problems with a .NET 3rd party control. Users who are not going through the proxy have no issues. The 3rd party control is nothing more than an AJAX dynamic tree that on each click requests all the nodes for each leaf. Now our clients claim that once users click on a node in the control, the control itself freezes in such a way that they don't see anything populate. Users see "Loading..." message appear but no new activity there afterwards. They have to leave the page and go back to the original page in order to view the new nodes. I've never worked with a reverse proxy before so I have googled quite a bit on the subject even found an article on SF. IBM/Tivoli has mentioned this issue before but this is about all they mention at all. While the IBM doc is very helpful, all of our AJAX is from the 3rd party control. I've tried troubleshooting using Firebug but by not being behind the reverse proxy, I'm unable to truly replicate the problem. My question is: does anyone have experience with reverse proxies and issues with AJAX sites? How can I go about proving what the exact issue is? Currently we're negotiating remote access so assume for the greater part that I will have access to a machine that's using the WebSEAL proxy. P.S. I realize this question might teeter on the StackOverFlow/ServerFault jurisdictional debate, but I'm trying to investigate from the systems perspective. I have no experience with reverse proxies (and I'm unclear on the benefits) and little with forwarding proxies.

• Experiences with BIRD for BGP?

  - by Shtééf

  We're currently using Quagga with Debian Linux to run a full table BGP router. The set-up has been dead simple up to now, but we've come to a point where I have to reconfigure the router quite a bit, and want to tighten things up. I've never really understood Quagga, and always found its documentation to be lacking. It appears to be mimicking Cisco, of which I only have basic understanding. BIRD has caught my eye recently. The couple of articles / presentations I found promote it as lightweight and more responsive under stress compared to Quagga. And it actually seems to have very decent documentation. So I'd like to know: Who's running BIRD right now, and in what kind of set-up? How is it stability-wise? I've read about it running in a couple of sites in production. Let's say I don't care at all for a Cisco-feel to configuration. How is configuration, maintainance, monitoring, etc. of BIRD in general? And any other notable experiences you may have with it.

• ip-up does not trigger when using built-in cisco vpn on mac osx lion

  - by Yasser Sobhdel

  I am using Cisco VPN client over lion and I want to make the ip-up and ip-down work. There is no sign of any action taken when I connect or disconnect this VPN connection. I really doubt whether the syntax has been changed or even this kind if connection is triggering the ip-up. Logically, it must be set over ppp but when using the following codes and instructions on them, there is no sign of any output in the log file: http://www.macfreek.nl/mindmaster/Modify_PPTP_Routing_Table http://www.aidanfindlater.com/use-vpn-for-specific-sites-on-mac-os-x Going for error, which there is no sign of it, using the following page: http://hints.macworld.com/article.php?story=20060616150640529 I couldn't find the /var/log/ppp/vpnd.log log file. Also the files are given full permission 0755 or a+x or even 777 using the following command: sudo chmod a+x /etc/ppp/ip-up Any clue on how to debug this would be appreciated. I am totally confused, netstat -rn -f inet doesn't show the routes. Even when the routes are added manually, closing the VPN connection does not run the ip-down and the routes must be deleted manually.

  Hello, I currently have 2 cPanel web servers that are little 1RU dual cpu quad core xeons. They have a lot of resources for processing and handling web requests, and never exceed more than 10% cpu usage. They also have plenty of RAM. The problem is though that they both have RAID 1 160Gb SAS hard disk drives in them that are 75% full, and growing by the day. I didnt think that the amount of disk usage would be so high, but due to the nature of the sites hosted, this has become an issue. The easy fix would be just to upgrade the hard drives to something bigger (probably not of the SAS variety), but I am thinking of keeping the current machines as "processing servers" and buying a central "storage server" with about 12TB of storage. The /home/ partition on each of the 1RU servers would be mounted to a NAS or SAN point on this central storage server. My questions are: - Has anyone got a cPanel setup where they mount /home/ to a NAS or SAN elsewhere? If so, can you provide details as to what you did and how it went :) - Any recommendations on networking? Is gigabit ethernet enough? Is TCP/IP going to be a noticable performance problem? Anyone used a TOE key? - Anyone benchmarked or had any performance issues with SAN over NAS? Any help greatly appreciated. Scott

• SharePoint 2010 User Profile Synchronization

  - by manemawanna

  Hello, I'm completely new to working with SharePoint and Windows Server, but last week I was given a small brief to play with SharePoint 2010 to see how I got along with it. Anyway I've set up a SharePoint server and had a mess around to get some new sites and pages created etc, but I'm now looking to have a try at importing some AD groups. As part of this I've look at these tutorials, here and here. So far I've got through to the process of starting the User Profile Service which works fine, but when I get it starting the User Profile Synchronization service it sits on starting. But when I refresh the page or go to the monitoring section it shows it as aborted. Now I'm new to administering servers like I say and when I start the User Profile Synchronization service it tries to run as NT AUTHORITY\NETWORK SERVICE and asks for a password so I've been providing it with the admin password, now I'm not sure if this is part of the issue or not as I've checked the log files and they seem to say that it doesn't have permissions, which is fair enough, but I can't see how you can change the account even if I wanted to. So if anyone could help it would be appreciated, if you need any further information to help with an answer, just let me know.

• Simple image editor to select area of image as wallpaper

  - by Kevin

  I've spent way to many hours looking for software to do the following simple task, so now I'll ask. I need software that will open an image and put a 'crop box' on it. You can set the 'crop box' to standard screen resolutions (1024x768) or define a custom one. You can move the 'crop box' around on the image to select the area you want. You can re-size the 'crop box' (selecting a corner and dragging w/mouse) and it maintains the correct aspect ratio. You can save the area in the 'crop box' to use as the Windows background. (The software doesn't need to set it as the background, I can do that myself in Windows XP.) The free software sites (CNET.com, etc.) have lots of image editing software that do things much more complicated than this simple task. I've spent too many hours downloading them to see if they will do this particular task. The ones I've tried would require manual trial and error to get the part of an image that I want saved as an image, with the correct aspect ratio so Windows doesn't screw with it (stretch, tile, crop) when I select it as the wallpaper.

• Self-hosting vs. Budget hosting - What are the economics?

  - by cdonner

  My current hosting provider (shared Linux, unlimited domains, < $10 per month, with about 20 sites) has been giving me a lot of grief lately. I am contemplating to just ditch them and repurpose the old Sun V20z that is sitting in my basement rack, and move the hosting in-house, literally. My math goes as follows: my company pays up to $80 a months for my home internet service, which would cover the upgrade from currently Fios to Comcast business internet with 5 static IPs. So this comes free. running the server will cost me about $180/year at the current rate of approx. $.2/kWh my time is free So, it seems that the my net cost of doing this would be about $80 anually, plus the work that goes into setup and maintenance. I will have to get email hosting somewhere, which I do not want to do myself. On the other side of the balance sheet, I'd likely get better uptime than my provider based on recent stats, will not get suspended and don't have to spend hours with customer support. Overall, I am not convinced. Has anybody actually done that? What was your experience, and did it pay off?

• Is there a way to tell what the download speed is from a site/server

  - by Memor-X

  i'm looking into which ISP i should go with at the place i'm moving into, one ISP which i have been told good things about has data limits (which when breached will drop your speed to dial-up speed) but multiple memberships which, apart from the cheapest membership, have the same data limits (the cheapest has a 10GB data limit) in their fine print, they say that each different membership has different port speeds, one particular part jumps out at me These speeds are the NBN (National Broadband Network) port speed and not the actual Internet data speed which will vary based on numerous factors including destination you are reaching, your network equipment, network congestion etc. i plan to use the net to download DLC and patch updates for games (particular the insanely large update for the Wii U) and games from Steam (if i find any good one other than this one JRPG) and downloading development resources from free sites like Deposit Files and Mediafire since one membership with a 1000GB data limit is $145 with the port speed being 12Mbps/1Mbps (cheapest) while another with the same limit is $190 with the port speed of 100Mbps/40Mbps (expensive) i am wondering how i can tell what the speed coming from site is since i don't want to be wasting money on speed that makes no difference (unlike memory which i rather have to spare) NOTE: the speeds are for a fiber optic network which where my new place is can only connect via fixed wireless which i may not be able to get with this ISP but if i can get this network then good NOTE 2: most of the resources i get from Deposit Files are always about 200 MB or less, if a resource pack is greater then it's split into multiple archives (like .7z.part) while Mediafire i have to see one bigger than 150MB NOTE 3: one update patch for a PS3 game is close to 4 GB (Disgaea 4) which i need to get access to the DLC and on the weekend i downloaded 5 GB for the Final Fantasy XIV Open Beta for the PS3 which took almost 5 hours

• Web server with static IP from cable provider

  - by Dmitri

  I have a subscription to 5 static IP addresses. I want to run a web server from behind a router. My network config is as follows: Server's local address is 10.1.10.2, has IIS running on it, port 80 and 443 (IIS is not my fault, had to be done) the server's ip address is static, the subnet mask is 255.255.255.0, gateway is 10.1.10.1, which is the local address of the cable modem / router / gateway thingy. All looks to be in textbook order as far as the LAN goes. I can get to anything on my LAN from any computer on my LAN, whether they have static IP or get it through DHCP from the cable modem/router thingy. however, I have no internet access form any of my LAN computers. I called Comcast tech support and they say they can connect to my modem/router just fine and can actually use it to ping any computer on the internet or any computer on my LAN from the router/modem (i checked, myself, this is in fact the case). However, nothing on my LAN has internet connectivity. I tried pinging the DNS servers, nothing. I tried directly typing in web sites' IP addresses, nothing, so doesn't seem to be a DNS issue. Any Ideas? What malfunction of a router could be causing such weird behavior? nay ideas or educated guesses are very much appreciated.

• Have powershell zip the contents of a bunch of folders, individual zip for each folder

  - by WebDevHobo

  Recently, I asked how to do this with a .bat file and an answer was provided. for /D %%d in (*.*) do "C:\Program Files\7-Zip\7z\7za.exe" a -tzip %%d.zip %%d However, this proved useful only for folders that have no spaces in their name. The reason being that batch will do the following: if the folder name is "jef's vacation pics", the variables will be: %%d = jef's %%e = vacation %%f = pics And then it tries to pass only %%d to the 7-zip program, which will not find such a folder and therefor will not create a zip file. I've tried looking up some tutorials, documentation sites and such, but I haven't been able to come up with an answer. There may be an answer, but I want to take this opportunity to try my hand at powershell. I was thinking that a function with 1 argument, that being the parent-folder of the sub-folders that need to be zipped, would be the best approach. So here's what I have, which doesn't work, probably due to my general in-experience with powershell: function zipFolders($parent) { $zip = "C:\Program Files\7-Zip\7z\7za.exe"; $parents | ForEach-Object $zip a -tzip }

• Getting 400 Bad Request when requesting by server name on nginx/uwsgi
