• IIS6 + PHP + FastCGI 500 Errors - Where to start looking?

  - by Bertvan

  I've set up IIS6 with FastCGI to use php-cgi.exe. I have some php websites by external parties, that I'm trying to run in a test environment. One of the websites just plain gives me a FastCGI Error Page. Question: Is there some way to enable logging somewhere so that I can get a bit more information on this problem? I have looked in Eventlog IIS Website log (c:\windows\system32\Logfiles) PHP log But no results, except the IIS Website log mentions a return of a 500 page. Question: Is there any other way to debug/check where things might be going wrong? Here is what the page looks like: FastCGI Error The FastCGI Handler was unable to process the request. Error Details: The FastCGI process exited unexpectedly Error Number: -1073741571 (0xc00000fd). Error Description: Unknown Error HTTP Error 500 - Server Error. Internet Information Services (IIS)

• How far should one take e-mail address validation?

  - by Mike Tomasello

  I'm wondering how far people should take the validation of e-mail address. My field is primarily web-development, but this applies anywhere. I've seen a few approaches: simply checking if there is an "@" present, which is dead simply but of course not that reliable. a more complex regex test for standard e-mail formats a full regex against RFC 2822 - the problem with this is that often an e-mail address might be valid but it is probably not what the user meant DNS validation SMTP validation As many people might know (but many don't), e-mail addresses can have a lot of strange variation that most people don't usually consider (see RFC 2822 3.4.1), but you have to think about the goals of your validation: are you simply trying to ensure that an e-mail address can be sent to an address, or that it is what the user probably meant to put in (which is unlikely in a lot of the more obscure cases of otherwise 'valid' addresses). An option I've considered is simply giving a warning with a more esoteric address but still allowing the request to go through, but this does add more complexity to a form and most users are likely to be confused. While DNS validation / SMTP validation seem like no-brainers, I foresee problems where the DNS server/SMTP server is temporarily down and a user is unable to register somewhere, or the user's SMTP server doesn't support the required features. How might some experienced developers out here handle this? Are there any other approaches than the ones I've listed? Edit: I completely forgot the most obvious of all, sending a confirmation e-mail! Thanks to answerers for pointing that one out. Yes, this one is pretty foolproof, but it does require extra hassle on the part of everyone involved. The user has to fetch some e-mail, and the developer needs to remember user data before they're even confirmed as valid.

• BizTalk 2009 - How do I do t"HAT"?

  - by StuartBrierley

  In my previous life working with BizTalk Server 2004, I came to view HAT (the Health and Activity Tracking tool) as one of my first ports of call in the case of problems with any of our BizTalk solutions.  When you move to BizTalk Server 2009 it is quickly apparent that HAT is no longer with us. HAT was useful in BizTalk 2004 mainly as it provided developers and administrators with a number of useful queries and views of what was going on inside BizTalk at runtime; when and what type of messages were received and sent, what messages had been suspended, what orchestration were running or suspended, you could even follow the process flow of a message or orchestration to see what was going on. With BizTalk Server 2009 much of the functionality of HAT can now be found in the BizTalk Administration console.  Select a BizTalk Group and you will be shown the Group Hub Overview page.  This provides a number of default queries that replicate some of those found in the old HAT. You can also use the Group Hub page to create new queries.  These can then be saved and loaded in other Group Hub instances - useful for creating queries in development for later use in Test, Psuedo-Live and Live environments. In the next few posts I am going to look at some of the common queries that we might miss from HAT and recreate them (or something close) using the new query option. Messages - last 100 received Messages - last 100 sent Messages - last 50 suspended Service instances - last 100 I have yet to try the updated Admin-HAT-Console in anger, and after using old-HAT for so long it may take some getting uesd to, but so far I would say that moving the HAT functionality into the BizTalk Administration console was probably the correct way to go.  Having one tool as the place to look for the combined functionality on offer certainly seems to be the sensible option.

• Apache - access two or more virtual hosts from outside

  - by André Alçada Padez

  I have an apache2 server running on my ubuntu system. I have two sites enabled: default (ServerName localhost) site2 (ServerName jslib) I run a windows Virtual Box Machine, to be able to test my stuff in IE. If i type the ubuntu's IP in the addressbar i get the localhost. I was wondering how can i access both (or more as i need it) from other machines. Thanks update I have configured the windows' hosts file like so: 10.0.2.2 localhost 10.0.2.2 jslib It works, but i am really looking for something that i can configure on the server side, and then just change the value of the URL, am i crazy?

• Does a single LACP channel over multiple switches increase redundancy?

  - by Sirch

  I am curious for opinions, findings, or evidence that having multiple interfaces bonded using LACP to ports in multiple switches can increase redundancy. Previously bonded interfaces have always been to a single switch, with a redundant channel to another port. Without getting into vendor specifics, my thought is that as this is a single LACP, the likelihood that an event or change could lead to a wide service outage. Without having the spare equipment or time to test this single channel over diverse switches, could anyone with a greater networking knowledge than myself, tell me if there a network side event that would bring down the network connectivity to a server that had created a bonded interface to two ports on separate switches? Does the use of bonded ethernet channels across multiple switches (that we are advised that we can use) from the server, provide both improved throughput (unquestionably), and improved redundancy (uncertain). Could/would network events such as switch failure, port migration, patching, recovery, etc, cause the channel for both server network interfaces to be unavailable? Thanks in advance.

• Can't set up IIS Web Server on Server 2008 x64 correctly (what have I missed?)

  - by balexandre

  Using a VM I installed Windows 2008 Server x64 and as the image below shows, added the IIS Role full image and assigned all role features of IIS full image But if I have an ASP.NET (aspx) page that does (C#) Session["test-session"] = "A"; and read in other page I always get nothing! NOTE: I do have an entire ASP.NET web application, the example above is to be succinct and explicit on what is the problem I'm facing. Can anyone know what do I have to do to the Server, so I can use the Session variables? All help is greatly appreciated, Thank you

• 32bit ODBC Postgres driver on Windows 2008 R2 x64

  - by uaise

  I'm trying to install the Postgres ODBC 32bit driver on a Windows 2008 R2 64bit machine. After installing it, with no errors, I go to the ODBC panel, the 32bit version under the /syswow64 folder and try to add the driver, select the Postgres driver from the list but I get an error 126, saying he can't find the driver at the specified path. The problem is that the path he shows me, is the exact path the driver is in, I double checked on the registery (on the HKLM\SOFTWARE\Wow6432Node\ODBC\ODBCINST.INI\ location) and it's fine there too. A couple more people on technet have the same issue too. Did anyone ever run into this? Any ideas would be greatly appreciated. edit: the driver works fine on my win7 x64 test machine, this behaviour only happens on the server.

• looping .mpeg dump

  - by Matt Cook

  Need to dump an MPEG2 file in a loop, either to stdout or a named pipe. This works: $ { while : ; do cat myLoop.mpg; done; } | vlc - This works on a text file containing "1234\n": $ mkfifo myPipe $ cat test.txt > myPipe & < myPipe tee -a myPipe | cat - (it correctly loops, outputting "1234" on every line). Why does the following NOT work? $ cat myLoop.mpg > myPipe & < myPipe tee -a myPipe | vlc myPipe I'm primarily interested in re-writing the first statement to remove the improper "cat myLoop.mpg" statement. Will be inputting into VLC, or into FFMPEG and then piped into VLC.

• Can you share wisdom on using HISTIGNORE in bash?

  - by sage

  I was reading the manpages for bash on the plane and I stumbled across the HISTIGNORE variable. To test it out, I immediately edited my .profile to define this variable: export HISTIGNORE=ls I tested it out and this is great! It excludes plain 'ls' commands from my history without excluding more interesting commands with lengthy paths, but having recently harvested a great deal of wisdom from SU I am eager to know what other commands superusers might recommend or other lessons learned. What can you share about using the HISTIGNORE variable in bash? (Note: I'm about to board my next flight and I have obligations upon arrival, so I will be absent for a number of hours before I can respond to comments...)

• Puzzled about PHP file permission and shared webhosting - what are some explanations?

  - by extrakun

  I have this issue with different web-hosting, particular upload scripts which can only upload to a folder only if it has 777 permission (which is risky). On the test server (on a different webhost), 755 works well. On another web-hosting, log files generated by PHP file functions cannot be write to some time, but other files are mysteriously unaffected (for instance, the log files for the entire week is 655, and they work well, but just today's log-file doesn't work unless it is set to 777). I am more of an application developer than a server backend expert, so these behaviours puzzle me to no end. Why are they happening? What can be done?

• How do I swap audio output of the left and right speakers?

  - by Manga Lee

  I have two speakers stereo speakers but when I use the sound control panel applet to test my audio configuration I get sound in the right speaker when the user interface indicates the right speaker and vice versa. Is there a way to swap the audio output from left to right and right to left? UPDATE: The reason for this question is that I've recently rearranged my workspace and because of physical constraints the left speaker has to go on the right side and vice versa. I could of course solve this problem with a hardware solution but I'd rather use a software solution if one is available.

• Sharepoint Document Library not receiving emails

  - by ria

  I have created a sharepoint document library which is email enabled. However when i send email to the designated email address from anywhere, i dont receive the email & attachment in the list. I have done some R&D and i hv found that in order to receive email from anywhere i have to expose my DNS of the sharepoint site to the outside world. Now i dont know whether it applies to the email address designated to me in the Active directory profile as well (my company domain email address). How to test that this email reception is working in the document library? I have tried sending an email from the sharepoint site and it works fine so the SMTP settings are correctly done.

• Do you know a script for email round trip monitoring?

  - by crazyfr

  Do you know a simple script that can do email round trip monitoring ? I want to monitor email service on A. I install the script on B. B sends an email to A A sends an auto-reply to B B knows that email service is working well. B restarts this test every 30min. If B didn't received replies, it sends an alert message. B could also monitor round-trip delay of emails. I have not access to the email service, I can only ask new end user email and configure auto-reply. B is an Ubuntu. Thanks!

• Excel - working in a bank

  - by Einsteins Grandson

  I am supposed to go to an interview to a bank for just supporting managers in projects. It's a part-time job and the thing is that bank uses Excel for everything. Modifications of tables of really lot of data... What can I expect to find in the test of Excel? I have some books that are around 1000 pages thick but I don't have time and also don't feel like reading everything that's in them. These are the books that I have: http://www.amazon.com/Excel-2010-Bible-John-Walkenbach/dp/0470474874/ref=sr_1_1?ie=UTF8&qid=1347571864&sr=8-1&keywords=excel+bible http://www.amazon.com/Excel-2010-The-Missing-Manual/dp/1449382355/ref=sr_1_1?ie=UTF8&qid=1347571884&sr=8-1&keywords=Excel+2010+The+Missing+Manual http://www.amazon.com/Microsoft-Excel-2010-In-Depth/dp/0789743086/ref=sr_1_1?ie=UTF8&qid=1347571904&sr=8-1&keywords=Microsoft+Excel+2010+In+Depth So, anybody knows a good online tutorial or a book that would contain the basics and was not that much thick? ;-) Thanks so much!!!

• Cheap server stress testing

  - by acrosman

  The IT department of the nonprofit organization I work for recently got a new virtual server running CentOS (with Apache and PHP 5), which is supposed to host our website. During the process of setting up the server I discovered that the slightest use of the new machine caused major performance problems (I couldn't extract tarballs without bringing it to a halt). After several weeks of casting about in the dark by tech support, it now appears to be working fine, but I'm still nervous about moving the main site there. I have no budget to work with (so no software or services that require money), although due to recent cut backs I have several older desktops that I could use if it helps. The site doesn't need to withstand massive amounts of traffic (it's a Drupal site just a few thousand visitors a day), but I would like to put it through a bit of it paces before moving the main site over. What are cheap tools that I can use to get a sense if the server can withstand even low levels of traffic? I'm not looking to test the site itself yet, just fundamental operation of the server.

• why do I get this mail server configuration error?

  - by Francesco

  <<The configuration of your mail servers and your DNS are not ok! The report of the test is: mail.mydomain.com. -> mydomain.com -> 78.47.63.148 -> static.148.63.47.78.clients.your-server.de Spam recognition software and RFC821 4.3 (also RFC2821 4.3.1) state that the hostname given in the SMTP greeting MUST have an A record pointing back to the same server.>> I have a A Record that points mail.mydomain.com to 78.47.63.148 (which is my given ip address for my vps) All other records are fine, so what's wrong and what record should I create to make it right?

• How do I dissuade users from using the same password with similar systems?

  - by Resorath

  I'm building a web application that connects to other web services (using strictly anonymous binding, so no user passwords are being used). However the web application maintains its own users itself, and is required to ask certain details such as e-mail addresses and public linking information to these other web services (for example, a username but not a password). I want to deter or prevent users from reusing passwords in my application that they have also used in the applications I'm linking to. For example, if I ask for their e-mail and provide me with their gmail address, I don't want them using their gmail password for my system. Another example would be reusing a password to a linked system in which they also gave me their username. One idea I had was to simply try using the information they gave me, along with the password they are trying to store and log in to these external web applications to test the password - then immediately unbind if I was successful and ask the user to use a different password. However I suspect there is a host of morale and legal issues there. The reason this is a big deal to me is accountability. My application is simply not funded enough to invest properly in security around user passwords. A salted, hashed password in a public SQL-like database is as secure as it gets. So if passwords and linked usernames or e-mails get out, I don't want my userbase compromised.

• Cheap, light, small Skype laptop?

  - by roufamatic

  My wife and son are heading out while I stay home to babysit some contractors. We discussed getting her a small, cheap laptop that would primarily be used for Skype. Good quality integrated video & mike are prerequisites, as is Windows (though I'd entertain OSX). Doesn't need to be large, a 12" screen is probably fine. If I went new, where should I look? And if I were going to test the used/craigslist waters, what specs are we talking about?

• USER_LOGIN audit log with incorrect auid value?

  - by hijinx

  We have a CentOS 6.2 x86_64 system that's logging what looks to be erroneous audit information. We were receiving alerts for failed logins by a user who wasn't actually trying to log in. After some diagnosis, we figured out that the source of the events is our tool that periodically checks to see if SSH is answering. When that happens, we see this log this entry: type=USER_LOGIN msg=audit(1340312224.011:489216): user pid=28787 uid=0 auid=501 ses=8395 subj=unconfined_u:system_r:sshd_t:s0-s0:c0.c1023 msg='op=login acct=28756E6B6E6F776E207A01234567 exe="/usr/sbin/sshd" hostname=? addr=127.0.0.1 terminal=ssh res=failed' This is the entry we get whenever there is an incomplete ssh connection, but usually the auid is the same as the ses= value. For some reason, on this system, it's using a particular user's auid, regardless of the login user. For example, ssh'ng to this system as [email protected] and cancelling before providing a password generates this error. Attempting to log to an unrelated account with a bogus password will also create an entry with the incorrect auid value.

• XAMPP OSX Snow Leopard & php ssh2 extension

  - by Joe

  I've been having problems getting the php ssh2 extension to work under xampp on Snow Leopard in my local test environment. I understand xampp is 32 bit and so the extension must be compiled as 32 bit and have found a couple of tutorials detailing how to do this. However, compiling the ssh2 extension requires the libssh2 library to be present for the compiler to access and I'm unsure how to compile libssh2 in 32 bit and force the extension compiler to in turn find/use it - currently it just reports the libssh2 library required version cannot be found. Any help would be much appreciated!

• Solaris x86: Non working keys on keyboard (<, >, #, |)

  - by Thomas

  Hello everyone, I have a new installation of Solaris 10 10/09 on x86 hardware. The attached keyboard has a normal German layout. The system is configured accordingly by 'kbd -s'. The generic keys (letter, number, umlaut) work fine. Unfortunately some keys like <, , | or # do not. They produce no output on the text console at all. I tried PS/2 and USB keyboards. I cannot test it under X11 as it is currently not working. Thanks.

• Install Trac Without Setting Up a VirtualHost in Apache?

  - by jobu1324

  I'm trying to set up Trac to test out it's functionality, and the only guides I can find online talk about setting up a VirtualHost. Right now I am under the impression that I need access to a DNS server to properly use the VirtualHost directive, and for various reasons I don't have access to one. Is it possible to set up Trac without setting up a VirtualHost? I haven't had any luck. If I run the site with tracd, it works - which means that at least part of it is set up properly. Right now all I have is an Apache Directory directive pointing to /pathToTracSite/htdocs/, and when I visit the trac location, all I get when viewing the site from a browser is an empty directory (which makes sense, because htdocs/ is empty). My server is running Apache2 I know I'm missing a lot here, because I don't understand Apache the Trac system very well - any help would be appreciated.

• Are these symptoms of a video card is dying?

  What I am getting from my PC: Scrambled text in the boot menu. The scrambled text dissapears and everthing goes normal after several restarts, or the computer has worked for some time. Display goes blank showing, windows kernel mode driver stopped responding. Sometimes the windows just hangs, I need to restart the pc for that. There used to be some scrambled colors in my windows, so I cleaned up my video carda and port and reinstalled the video card, things are something right. The pc runs normally for hours in safe mode, as diffault display driver works at that case. My PC specs: Core 2 Duo processor 2 GB RAM NVIDIA EN210 SILENT GPU Windows 8 Drivers details: NVIDIA drivers - v331.65, told to be fully compatible with Win8 Currently I am installing Windows 7 and will be putting the older version of driver v320 to test, yet I'm really confused weather my GPU is dying or still on go.
