  • URL Rewriting Problem

    - by Eray
    I'm trying to rewrite my URL's subdomain. http://username.domain.com will show content of http://www.domain.com/user.php?u=username but URL stay as http://username.domain.com . (I mean url masking) (Username's can contain a-z 0-9 and hypens) Also if subdomain is www or api, don't redirect them I'm using this for my .htaccess RewriteEngine on RewriteCond %{REQUEST_URI} !^/index\.php$ RewriteCond %{HTTP_HOST} !^www\.domain\.com RewriteCond %{HTTP_HOST} ^([^.]+)\.domain\.com RewriteRule .* /user.php?u=%1 [L] (After @mfarver's advice) I'm trying this RewriteEngine on RewriteRule .* /user.php?u=%1 [L] but this time getting 500 Internal Server error: [Mon May 30 20:10:44 2011] [alert] [client 81.6.xx.xxx] /home/blablabla/public_html/.htaccess: AllowOverride not allowed here (from error log) My server's httpd.conf file's virtualhost settings <VirtualHost 109.73.70.169:80> <IfModule mod_userdir.c> UserDir disabled UserDir enabled USERNAME </IfModule> <IfModule concurrent_php.c> php4_admin_value open_basedir "/home/USERNAME/:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp" php5_admin_value open_basedir "/home/USERNAME/:/usr/lib/php:/usr/local/lib/php:/tmp" </IfModule> <IfModule !concurrent_php.c> <IfModule mod_php4.c> php_admin_value open_basedir "/home/USERNAME/:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp" </IfModule> <IfModule mod_php5.c> php_admin_value open_basedir "/home/USERNAME/:/usr/lib/php:/usr/local/lib/php:/tmp" </IfModule> <IfModule sapi_apache2.c> php_admin_value open_basedir "/home/USERNAME/:/usr/lib/php:/usr/php4/lib/php:/usr/local/lib/php:/usr/local/php4/lib/php:/tmp" </IfModule> </IfModule> ServerName DOMAIN.net ServerAlias *.DOMAIN.net <Directory "/home/USERNAME/public_html"> Options FollowSymLinks Allow from all AllowOverride All </Directory> DocumentRoot /home/USERNAME/public_html ServerAdmin [email protected] UseCanonicalName Off CustomLog /usr/local/apache/domlogs/DOMAIN.net combined CustomLog /usr/local/apache/domlogs/DOMAIN.net-bytes_log "%{%s}t %I .\n%{%s}t %O ." ## User USERNAME # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup USERNAME USERNAME </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup USERNAME USERNAME </IfModule> ScriptAlias /cgi-bin/ /home/USERNAME/public_html/cgi-bin/ # To customize this VirtualHost use an include file at the following location # Include "/usr/local/apache/conf/userdata/std/2/USERNAME/DOMAIN.net/*.conf" </VirtualHost> Also *.DOMAIN.net added to my DNS ZONES as A record.

  • Configuring external SMTP server on Azure VM - messages staying in queue

    - by Steph Locke
    I have an external SMTP provider: auth.smtp.1and1.co.uk I am trying to send SQL Server Reporting Services emails via this on an Windows 2012 Azure VM. It is configured sufficiently correctly for emails to be generated, but I've not configured something or mis-configured something as the emails then stay in the queue. Setup details Configured SMTP Virtual Server General: IP Address: Fixed value Access: Access Control: Authentication: ticked Anonymous access Access: Connection Control: All except the list below (which is empty) Access: relay restrictions: Only the list below (which contains 127.0.0.1), ticked 'allow all..' option Delivery: Outbound Security...:Basic Authentication with username and password completed, ticked TLS encryption Delivery: Outbound connections...:TCP port=587 Delivery: Advanced: FQDN=ServerName, smarthost=auth.smtp.1and1.co.uk I then set the following SSRS rsreportserver.config values: <SMTPServer>100.92.192.3</SMTPServer> <SendUsing>2</SendUsing> <SMTPServerPickupDirectory> c:\inetpub\mailroot\pickup </SMTPServerPickupDirectory> <From>[email protected]</From> Tried so far 1) turning the smtp service off and on again (just in case) 2) run SMTPDiag with no errors (also no emails) 3) tried turning off the firewall for the ports (and more generally to see if it made a difference) 4) tried generation from powershell which resulted with message in queue 5) added 25 and 857 as endpoint 6) perused the event log and found some warnings that appear to be about the recipient Message delivery to the remote domain 'gmail.com' failed for the following reason: Unable to bind to the destination server in DNS. Message delivery to the host '212.227.15.179' failed while delivering to the remote domain 'gmail.com' for the following reason: The remote server did not respond to a connection attempt. 7) tried pinging but this appears to be blocked on azure 8) tried more powershell sending on different domains variants (localhost, boxname, internal ip used in smtp properties, 127.0.0.1) - none resulting in success 9) tried adding a remote domain - no change Could anyone recommend what step 10 should be in fixing this issue please?

  • mysql startup, shtudown and logging on osx

    - by Joelio
    Hi, I am trying to troubleshoot some mysql problems (I have a table I cant seem to delete or drop, it hangs forever) I have 10.5.8 osx, I dont remember how/if I installed mysql, here is what I know: it automatically starts on boot the process looks like this: /usr/local/mysql/libexec/mysqld --basedir=/usr/local/mysql --datadir=/usr/local/mysql/var --pid-file=/usr/local/mysql/var/Joels-New-Pro.local.pid _mysql 96 0.0 0.0 75884 684 ?? Ss Sat06PM 0:00.02 /bin/sh /usr/local/mysql/bin/mysqld_safe when I run: /usr/local/mysql/libexec/mysqld --verbose --help it says: /usr/local/mysql/libexec/mysqld Ver 5.0.45 for apple-darwin9.1.0 on i686 (Source distribution) it seems to use my.cnf from /etc/my.cnf Now here are my questions: I dont see anything in the startupitems that remotely looks like mysql ls /Library/StartupItems/ BRESINKx86Monitoring ChmodBPF HP IO HP Trap Monitor Parallels ParallelsTransporter 1.) So how does it startup automatically? 2.) How do I start & stop this type of installation? Also, looking at the config, the logs have no values: /usr/local/mysql/libexec/mysqld --verbose --help|grep '^log' log (No default value) log-bin (No default value) log-bin-index (No default value) log-bin-trust-function-creators FALSE log-bin-trust-routine-creators FALSE log-error log-isam myisam.log log-queries-not-using-indexes FALSE log-short-format FALSE log-slave-updates FALSE log-slow-admin-statements FALSE log-slow-queries (No default value) log-tc tc.log log-tc-size 24576 log-update (No default value) log-warnings 1 3.) Does that mean there is no logging enabled in mysetup? thanks in advance! Joel

  • Are there any Microsoft Exchange Clients for iOS and Android that store their local data in an encrypted manner?

    - by Zac B
    I don't feel like this is a product recommendation question, more of a "does this tech even exist and is it feasible" question, but if I'm wrong, feel free to give this question the boot. Context: Our company has a bunch of traveling employees who access the company's Exchange server via thier iDevices or android phones, but because of the data protection laws in the state where our company is based (and the nature of the data our company works with), a recent security audit found that all mobile devices (laptops, phones, etc) operated by our company need to have all company correspondence and related data encrypted all the time. For laptops, that was easy: BitLocker or TrueCrypt, problem solved. For phones and tablets, however, I'm stumped. Sure, you can put lock screens/passwords on the phones, but the data is still accessible via external extraction, as law enforcement authorities already know. Question: Are there any clients for Microsoft Exchange that run on iOS or Android which store local data encrypted? The people using our mobile devices do a lot of their work while offline, so just giving them OWA access with SSL connection security isn't enough. Are there apps/technologies that present an additional login credential prompt to decrypt locally stored data in the app's storage area on the phone? My gut reaction when I started looking into this was "that doesn't sound like something Apple would allow into the App Store", but I've been wrong before...

  • How can I use the Homebrew Python with Homebrew MacVim on Mountain Lion?

    - by Stephen Jennings
    I originally asked and answered this question: How can I use the Homebrew Python version with Homebrew MacVim? These instructions worked on Snow Leopard using Xcode 4.0.1 and associated developer tools. However, they no longer seem to work on Mountain Lion with Xcode 4.4.1. My goal is to leave the system's version of Python completely untouched, and to only install PyPI packages into Homebrew's site-packages directory. I want to use the vim_bridge package in MacVim, so I need to compile MacVim against the Homebrew version of Python. I've edited the MacVim formula to add these to the arguments: --enable-pythoninterp=dynamic --with-python-config-dir=/usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/Current/lib/python2.7/config Then I install with the command: brew install macvim --override-system-vim --custom-icons --with-cscope --with-lua However, it still seems to be somehow using Python 2.7.2 from the system. This seems strange to me because it also seems to be using the correct executable. :python print(sys.version) 2.7.2 (default, Jun 20 2012, 16:23:33) [GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] :python print(sys.executable) /usr/local/bin/python $ /usr/local/bin/python --version Python 2.7.3 $ /usr/local/bin/python -c "import sys; print(sys.version)" 2.7.3 (default, Aug 12 2012, 21:17:22) [GCC 4.2.1 Compatible Apple Clang 4.0 ((tags/Apple/clang-421.0.60))] $ readlink /usr/local/lib/python2.7/config /usr/local/Cellar/python/2.7.3/Frameworks/Python.framework/Versions/Current/lib/python2.7/config I've removed everything in /usr/local and reinstalled Homebrew by running these commands: $ ruby <(curl -fsSkL raw.github.com/mxcl/homebrew/go) $ brew install git mercurial python ruby $ brew install macvim (nope, still broken) $ brew remove macvim $ ln -s /usr/local/Cellar/python/..../python2.7/config /usr/local/lib/python2.7/config $ brew install macvim

  • MacPorts pHash not showing up in Python

    - by Nitzan Wilnai
    I am having a problem where python does not show pHash installed even though I installed it using macports. I made sure I am using the MacPorts version of Python by doing: sudo port select --set python python27 I then installed pHash by doing: sudo port install pHash. It installed without any errors. When I call help('modules'), I do not see pHash listed among the installed packages. Any ideas on why python is not seeing the pHash install by MacPorts? Calling port select --list python shows the following: Available versions for python: none python25-apple python26-apple python27 (active) python27-apple Printing out sys.path outputs the following: (reformatted to make it easier to read here) ['/Library/Python/2.7/site-packages/boto-2.9.9-py2.7.egg', '/Library/Python/2.7/site-packages/setuptools-0.9.8-py2.7.egg', '/Library/Python/2.7/site-packages/pip-1.4.1-py2.7.egg', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload', '/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages', '/Library/Python/2.7/site-packages'] Can anyone help?

  • Why do I have 55 local area connections in ipconfig?

    - by RMorrisey
    Windows Vista Home Premium. I should mention that I am having no problem whatever getting an internet connection. When I type "ipconfig" in the console, I get (55!) messages of 3 lines each, listing a ton of disconnected network connections. My PC only has one network card. Each message looks like this: Tunnel adapter Local Area Connection* 55: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : These don't cause a major problem; they make it a pain, though, to fish upward and find my IP address. How can I get rid of them? Edit: Actually, a few connection numbers are randomly missing from the sequence; so, it's really more like 30 or 40 connection messages, rather than all 55. Not sure why that is, either.

  • Exchange 2003: Unrestrict send mail size for specific users / groups?

    - by Kip
    Good (insert appropriate time of day here) SF folks, I have the following situation; We have a message size limit for sending set at 20mb in Global Settings | Message Delivery. We have a limit of 50mb set at an external 3rd party spam vendor. I need to enable some users to be able to send messages that are upwards of around 40mb in size. However, when I set the Sending Message Size Maximum to 50mb within the delivery restrictions of a users exchange properties, it would appear that this does not win. It seems that the lowest value wins for this situation. I need to be able to allow certain users to send messages larger than the 20mb limit, but to have everyone else have the 20mb limit in place. How can I do this? The only way I could see was to raise the limit set in Global Settings | Message Delivery to 50mb and then set everyone elses (bar the people who need increased limit) delivery restrictions max size down. But I cannot see an easy way to do the last bit hence my post here looking for advice. There are valid reasons we need to send mail this size and whilst we are putting together other mechanisms for delivery this data, we still need to get this put in place. Thanks in advance Kip

  • Debugging "clogged" TCP connections

    - by Nikratio
    I'm having trouble with an internet connection that seems to randomly "freeze" arbitrary tcp connections. The connections stay established, but no data is coming through. When this happens, netstat still shows the connection status as ESTABLISHED on both the local computer: Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name Timer tcp 0 53 192.168.0.10:41129 173.255.235.238:143 ESTABLISHED 8219/gnutls-cli on (79.31/13/0) ..and the remote server: Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name Timer tcp 0 0 173.255.235.238:143 68.5.174.98:41129 ESTABLISHED 5303/imapd off (0.00/0/0) However, it seems that no data at all is transferred. If I run strace on the local and remote process, both just show a repeating sequence of select calls (with different fds of course), e.g. select(6, [0 5], NULL, NULL, {0, 50000}) = 0 (Timeout) select(6, [0 5], NULL, NULL, {0, 50000}) = 0 (Timeout) select(6, [0 5], NULL, NULL, {0, 50000}) = 0 (Timeout) The internet connection overall does not seem affected, I can still establish new connections to the same service on the same server without any problems. However, the affected local applications seem to be unaware of the problem and just hang. When I look at a packet capture of this connection on the client side, the last thing that happens is that the client transmits some data, then nothing happens for about 1100 seconds, and then several TCP Retransmission requests go out, with intervals increasing from 4 seconds to 130 seconds. No activity is captured after that. After about 10 minutes, the connection on the remote end disappears from the netstat (I wasn't able to catch any intermediate state), but still stays ESTABLISHED on the local end. Finally, after some more minutes, the local application aborts with a timeout and disappears from the local netstat output as well. Does anyone have a suggestion of how I could debug this further to find out where the problem lies and how to fix it? Additionaly and/or as a temporary workaround: is is there some way to globally reduce the timeout on client and/or server to reduce the time before the local application aborts?

  • Built local glibc, broke system, how do I ssh without parsing the .bashrc?

    - by Mikhail
    The cluster I am on had really old build tools and I needed to use CUDA5. I'm a pretty clever dude and I planned on building the necissary tools. So, I built a local copy of gcc, bintools, and glibc. Everything a CUDA5 could want. All builds finished without error. and I tested gcc and bintools. Everything was wonderful and I built and ran a few of the programs. I set up the LD_LIBRARY_PATHs in the .bashrc and logged back in, expecting a productive night ahead. To my horror I realized that everything is dynamically linked. Now I can't do simple commands like ls [ex@uid377 ~]$ ls ls: error while loading shared libraries: __vdso_time: invalid mode for dlopen(): Invalid argument and I can't do commands to fix the problem like rm or vim! Is there a way for me to ssh but also to ignore .bashrc file? Any suggestions are much appreciated. This machine is obviously under maintained and I don't know when I could have administrator support.

  • Exchange 2007 relay from sendmail, message "Undelivered". Possible reasons?

    - by garlicman
    Note: This is my re-post from Stackoverflow. I've been messing with a test environment for security purposes where a DMZ RHEL5 sendmail server is used as a relay for an Exchange 2007 server. Exchange is working in the environment, I have Vista and XP VMs using Outlook on the Domain to send e-mail to each other. I've been trying to simulate an external internet VM sending an e-mail to the DMZ sendmail relay, which forwards to the Exchange server. Before everyone thinks this is too big a problem/question, I've followed the sendmail/Exchange guides and all I want to know is how I can determine why a relayed message/e-mail in Exchange is "Undelivered". Basically I send a SMTP message to the sendmail server, which relayed to my Exchange. The /var/log/maillog shows the e-mail being relayed to Exchange. Nov 17 13:41:22 externalmailserver sendmail[9017]: pAHIfMuW009017: from=<[email protected]>, size=1233, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA, relay=[10.50.50.1] Nov 17 13:42:17 externalmailserver sendmail[9050]: pAHIfMuW009017: to=<[email protected]>, delay=00:00:55, xdelay=00:00:36, mailer=relay, pri=121233, relay=mailserver.xyz.local. [192.168.1.20], dsn=2.0.0, stat=Sent (<[email protected]> Queued mail for delivery) This is good, but the To never receives the e-mail from Exchange. So I started poking around Exchange. In the "Message Tracking" Troubleshooting Assistant I queried the processed messages and found this: (I had to copy and paste the cells... sorry for the format) 2011/11/17 RECEIVE SMTP <[email protected]> "Undelivered Mail Returned to Sender" yourboss@xyz.local zbob@xyz.local 192.168.100.10 MAILSERVER\DMZ Relay yourboss@xyz.local I just want to know if anyone has any suggestions on why the DMZ Relay Connector I setup isn't relaying and is instead returning the forwarded e-mail to sender as Undelivered? My Exchange Relay Receive Connector is pretty simple. The Exchange server's FQDN is set as the HELO response, all available IP addresses can receive relayed e-mail, and the IP address of my sendmail server is specifically set as a remote server.

  • Do entries in local 'hosts' files override both forward and reverse name lookups?

    - by Murali Suriar
    If I have the following entries in a hosts file: 192.168.100.1 bugs 192.168.100.2 daffy.example.com 192.168.100.3 elmer.example.com. Will IP-name resolution attempts by local utilies (I assume using 'gethostbyaddr' or the Windows equivalent) honour these entries? Is this behaviour configurable? How does it vary between operating systems? Does it matter whether the 'hosts' file entries are fully qualified or not? EDIT: In response to Russell, my test Linux system is running RHEL 4. My /etc/nsswitch.conf contains the following 'hosts' line: hosts: files dns nis If I ping any of my hosts by name (e.g. bugs, daffy), the forward resolution works correctly. If I traceroute any of them by IP address, the reverse lookup functions as expected. However, if I ping them by IP, ping doesn't appear to resolve their host names. My understanding was that Linux ping would always attempt to resolve IPs to names unless instructed otherwise. Why would traceroute be able to handle reverse lookups in hosts files, but ping not?

  • Sendmail Tuning For Batch Mail Jobs

    - by Kyle Brandt
    I have a webservers that send out emails to a sendmail relay server as a batch job. The emails need to be accepted by the relay sendmail server as fast as possible, however, they do not need to go out (be relayed) very quickly. I am seeing a couple timeouts once and a while from the webserver trying to connect to the relay server. The load currently is about 30 emails a second for a couple minutes. There are quite a few tuning options for sendmail in the sendmail tuning guide. What I am focusing on now is the Delivery Mode: Delivery Mode There are a number of delivery modes that sendmail can operate in, set by the DeliveryMode ( d) configuration option. These modes specify how quickly mail will be delivered. Legal modes are: i deliver interactively (synchronously) b deliver in background (asynchronously) q queue only (don't deliver) d defer delivery attempts (don't deliver) There are tradeoffs. Mode i gives the sender the quickest feedback, but may slow down some mailers and is hardly ever necessary. Mode b delivers promptly but can cause large numbers of processes if you have a mailer that takes a long time to deliver a message. Mode q minimizes the load on your machine, but means that delivery may be delayed for up to the queue interval. Mode d is identical to mode q except that it also prevents lookups in maps including the -D flag from working during the initial queue phase; it is intended for ``dial on demand'' sites where DNS lookups might cost real money. Some simple error messages (e.g., host unknown during the SMTP protocol) will be delayed using this mode. Mode b is the usual default. If you run in mode q (queue only), d (defer), or b (deliver in background) sendmail will not expand aliases and follow .forward files upon initial receipt of the mail. This speeds up the response to RCPT commands. Mode i should not be used by the SMTP server. I currently have the CentOS default modes: Sendmail.cf: DeliveryMode=background Submit.cf: DeliveryMode=i Is sendmail.cf/mc for outgoing email from relay (to the intertubes) and sumbit.cf/mc for incoming eamil (from my webservers). Would it make sense to change the outgoing delivery mode to queue? If I did, what would the outbound email flow behave like? If this is the right thing to do, can anyone show me example mc configurations for this change? If it isn't, what recommendations are there for these constraints?

  • How to set up hosts file for local environment?

    - by n00b0101
    I'm trying to create subdomains on my localhost and am way out of my territory... I'm running MAMP on my Mac OS X and I thought/think I had/have to do the following: (Assuming I want to create me.localhost.com and you.localhost.com) (1) Edit /private/etc/hosts Right now, it looks like this: 127.0.0.1 localhost 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost So, do I just make it: 127.0.0.1 localhost 127.0.0.1 me.localhost.com 127.0.0.1 you.localhost.com 255.255.255.255 broadcasthost ::1 localhost fe80::1%lo0 localhost (2) I'm assuming I don't need to mess with DNS at all because it's local? So, the hosts file should suffice? (3) And then, I need to edit my httpd.conf file to include virtual hosts? I tried this, but it's not picking it up... NameVirtualHost * <VirtualHost *> DocumentRoot "/Applications/MAMP/htdocs" ServerName localhost </VirtualHost> <VirtualHost *> DocumentRoot "/Applications/MAMP/htdocs/me.localhost.com" ServerName me.localhost.com </VirtualHost> <VirtualHost *> DocumentRoot "/Applications/MAMP/htdocs/you.localhost.com" ServerName you.localhost.com </VirtualHost> Not sure if I'm way off-base here... Help is greatly appreciated!

  • Am I able to forward traffic from an external subdomain to a specific local host?

    - by George Bowman
    I apologise in advance if the question doesn't make sense, please let me know. I've got a small LAN (~10 Virtual Servers) using Win Server 2008 as a DNS server. This is behind a smoothwall express 3.0 firewall with ports forwarded for specific services. I have a domain (123-reg) with the NS's that of afraid.org (DynamicDNS) and subdomains pointed to my (Dynamic) IP address e.g. subdomain1.example.com - 123.456.789.101. I think that adequately explains my set up. My question is, am I able to have subdomains e.g. subdomain1.example.com only point to a specific local host? Like so: subdomain1.example.com:80 - firewall(external facing) - server1.example.com:80 subdomain2.example.com:80 - firewall(external facing) - server2.example.com:80 I don't actually necessarily want to use port 80, otherwise I would just use VirtualHosts on apache, it is just an example port. Currently I can use either subdomain1.example.com OR subdomain2.example.com and they will both point to server1.example.com:80 I do not have to stay using Win Server 2008 for DNS, I am more than happy to move over to BIND if needs be, it was just easier to use Win Server 2008's DNS. I do not know if this is even possible, I have a feeling it isn't as I've only got one external IP address but any information is useful!

  • How can I use an own asp page as 404 error page on a Windows 7 pro IIS 7.5 local installation

    - by Edelcom
    Running Windows 7 Pro Running local IIS 7.5 ( for web development purposes ) Edited hosts file to be able to use http://www.sitestepper.dev Site build in subfolder of the inetpub/wwwroot/staplijst Site can be viewed using http://www.sitestepper.dev/staplijst/whatever-page.htm I have an http://www.sitestepper.dev/p.asp page I would like to call when an unknown page is requested. This technique works fine on the deployed version of this web site ( deployed on an Windows 2003 server running IIS 7 - not sure about the 7 but it is the version deployed with Windows 2003 server ). I tried ( in the Edit Custom Error Dialog ) : Execute a URL on this site: with value /staplijst/p.asp and Respond with a 302 redirect: with value http://www.sitestepper.dev/staplijst/p.asp I tried this in the properties of the 'Default Web Site' , and I tried this at the staplijst level. Even tried it with values without the /staplijst. I restarted the default web site after each change. And even stopped/started the Web service. But nothing seems to work, I keep getting the 'Server Error In Application "DEFAULT WEB SITE"' , HTTP Error 404.0 error. What am I missing here - probably something obvious, but I don't see it ? Thanks in advance

  • SharePoint blog site won't search local site... you can only search for Mysites and users

    - by Don
    I have a Howto company Blog site that i post to for my clients to access for help. For some reason it has stopped letting anyone search on it. I can search for Mysites or users. But when you drop down the tab to search: This Site: "blog site name" you get the following reply: No results matching your search were found. Check your spelling. Are the words in your query spelled correctly? Try using synonyms. Maybe what you're looking for uses slightly different words. Make your search more general. Try more general terms in place of specific ones. Try your search in a different scope. Different scopes can have different results. I have tried the following command: from the Index server 1-net stop osearch 2-net start osearch 3-iisreset /noforce But still not able to search a local blog site I can only search for users and Sites. please help Don

  • Looking for easiest, most simple solution to run a customised DNS Server for my local network on Windows 7.

    - by Jamie G
    I need to forward some websites, such as http://testing.server/ to an fixed IP address on my local network. I can do this easily on one computer using the hosts file. However, I need this to work for all machines on my network. I think the best way to do this will be to setup my own DNS Servers and add the custom DNS settings there. However, I'm looking for the simplest way possible to do this - I really don't want to spend hours setting up Unix Servers and running tricky terminal based scripts just to do this! My server is a standard Windows 7 machine. My dream would be a nice simple windows program with a GUI where I could input my ISP's DNS server and it would use those records, unless I had specifically set up my own DNS for a domain to use instead. If it had a web based admin system that was accessible from another computer on the network that would be even better. Does anyone know of anything that can do this? Many thanks indeed.

  • Issue with SSH on Ubuntu - Local connection ok, remote connection - Is it me or my ISP?

    - by Benjamin
    I have an issue with a server running Ubuntu 12.04, I am trying to set up a remote connection so I can access the server at my work from out of town. I have installed the SSH server and all that stuff, and I have reassigned the default port from 22 to 3399. A local connection from any OS can connect on the 192.168... address, but in no way can I get a connection on the actual IP address. I believe my configuration is correct, and I will attach it. If I have done something wrong in the config, please tell me and I will make a change to it. I honestly think that the Router that my ISP provided is horrible, and although the port for ssh is forwarded, it might be stopping any traffic coming inbound. Is there anything I can try to verify this? /var/log/auth does not show any error when I connect VIA our static IP. I have included all values not commented out below: (sshd_config) Port 3399 ListenAddress 0.0.0.0 Protocol 2 HostKey /etc/ssh/ssh_host_rsa_key HostKey /etc/ssh/ssh_host_dsa_key HostKey /etc/ssh/ssh_host_ecdsa_key UsePrivilegeSeparation yes KeyRegenerationInterval 3600 ServerKeyBits 768 SyslogFacility AUTH LogLevel INFO LoginGraceTime 120 PermitRootLogin yes StrictModes yes UseDNS no RSAAuthentication yes IgnoreRhosts yes RhostsRSAAuthentication no HostbasedAuthentication no PermitEmptyPasswords no ChallengeResponseAuthentication no PasswordAuthentication yes GSSAPIAuthentication no X11Forwarding yes X11DisplayOffset 10 PrintMotd no PrintLastLog yes TCPKeepAlive yes AcceptEnv LANG LC_* Subsystem sftp /usr/lib/openssh/sftp-server UsePAM yes Am I doing this wrong? port forwarding image

  • I have just created a subnet for a local network, connecting to a standalone server on another network, now I cannot connect to the internet

    - by Seth
    I am just learning some new aspects of servers and networking. We have a network of 5 subnets that all interconnect with each-other. In order to get two computers on the subnet that we were setting up, I changed the IP from the subnet where the standalone server is on (where they used to be set up)to the local subnet we are remotely hooking up. Likewise I also changed the gateway to coincide with the new subnet. Only problem is that since doing this, I am unable to establish a connection to the internet. I can ping the server and correspong gateway & DNS server, but cannot get connected to the internet. We do have a dumb-switch (non-programmable) connected that receives both the internet and private network inputs and distributes (or should do so) to about 5 other computers. Bottom line, I cannot currently connect to the internet, and am wondering what could be causing this.. It is likely something very obvious and pardon me being more vague than I probably should be, but I could use some help resolving this! Thanks for any help!

  • Adding a 2008 server to a 2003 Domain with DNS devolution?

    - by mvdwege
    I'm running into a problem adding a 2008 server to our existing 2003 domain, and as I am not a Windows admin, I'm not getting the problem here. Some reading around on Technet seems to indicate that DNS devolution is the issue. Here's the setup: DNS for the entire company is hosted on a Unix server running Bind, including the service records for the Windows domain. Our toplevel is company.local, and functional domains are in subdomains, such as mgt.company.local (our management servers). Our Windows servers live mostly in office.company.local, but some of them live in .mgt.company.local and .customers.company.local. The 2003 servers all succesfully authenticate against company.local as the Windows domain. Their position in the infrastructure is set by setting the primary DNS suffix under the network settings and the computer name dialog. Trying to do the same with a brand new 2008 install throws an error though: "Changing the Primary Domain DNS name of this computer to office.company.local failed [...] The specified server cannot perform the requested operation" I tried googling, but the closest I came was the Technet article on DNS Devolution, and I can't make heads nor tails on how to apply that to my case. Addendum 2012-10-23: The problem is not joining the domain, that works, the problem is that it joins with the wrong name, as .company.local, instead of .office.company.local. So far everything works, but I'm rather afraid to run production like this, because sooner or later something is going to complain about the AD name not matching DNS.
