• Connecting multiple ColdFusion 10 instances to a single Apache 2.2 server

  - by Adam Cameron

  This is on Windows 7 Home Premium edition. I have got two ColdFusion 10 (updater 2) instances: "cfusion" (the default one), and "scratch". I have got a single instance of Apache 2.2 running. Within Apache, I have set up two virtual hosts, each of which needs to be served by a different ColdFusion instance. Each of the CF instances serves files fine via Tomcat's internal web server. Apache serves vanilla HTML files fine too. So both CF instances, and both virtual hosts separately work OK. I can get wsconfig.exe to connect either one of the CF instances to the Apache server, and serve CF files via Apache & that instance. However I cannot find a way of connecting the second CF instance to Apache as well, so that both CF instances are conected, each serving one of the virtual hosts. WSConfig doesn't seem to understand the notion of "multiple CF instances", and the changes it makes to the httpd.conf (via mod_jk.conf) does not seem to be implemented in such a way as to accommodate multiple CF instances talking to a single Apache instance, or multiple virtual hosts. I freely admit to not being confident enough with how mod_jk (or even really httpd.conf) works to be able to guess if I can change stuff to make it work. If I try to add the second CF instance using WSConfig, I just get a message "the web server is already configured for ColdFusion". Be that as it may... not the instance of ColdFusion I want to connect it to! If I remove the existing connector to whichever instance is already connected, I can then connect the other one no problems. Not that this helps, but it demonstrates that the CF instance can connect to Apache. This all used to be fairly straight fwd under older versions of CF and JRun :-( The only docs I have found are on the "Connect multiple Apache virtual hosts on a web server to a single ColdFusion server" page, but that specifically only deals with a single CF instance. There is no equivalent page for multiple CF instances. I'm kinda hoping I can move some of the mod_jk config into my virtual host entries in httpd-vhosts.conf (this is how it used to work for JRun), but I've no idea what to put where. I think I've covered all the necessary info here? If not, sing out and I'll add more. Thanks. PS: tried to specifically tag this as "ColdFusion-10" as the answer will be different from previous CF versions, but it won't let me cos my rep on this site is too low (odd how it doesn't consider my rep from other S/O sites...). If someone with sufficient rep can add it, that'd be cool: it's probably a valid tag to have. Ta.

• PC monitors shut off and system hangs while playing 3D games, but sound continues - Diagnosis?

  - by Jon Schneider

  Two days ago, I started running into a problem with my Windows PC: The PC's two connected monitors simultaneously lose signal and go black (as though the PC had been powered off). The keyboard's Numlock, Capslock, and Scroll Lights will become "stuck" in their current positions, as though the PC is hung. (For example, the Numlock light on the keyboard remains lit regardless of me pressing the Numlock key repeatedly.) No keyboard input does anything. (Ctrl+Alt+Del, Ctrl+Shift+Esc, Ctrl+C, etc.) However -- Whatever sound/music the PC was playing continues to play, and the PC's fans continue running, so the PC hasn't powered itself off or rebooted itself. Opening up the case, the graphics card is pretty hot to the touch. I had this happen 3 times in one evening. In all cases, I was playing a game with 3D graphics when the problem occurred (Torchlight, Minecraft, Magic: The Gathering 2012, Avadon: The Black Fortress demo). I have yet to have the problem happen when I'm not playing a game. This system has been running stable for about 2.5 years prior to this. I didn't make any changes to the system prior to the problem starting to occur. System specs: OS: Windows 7 64-bit Processor: Intel Core 2 Duo E7200 Wolfdale 2.53GHz Video Card: XFX GeForce 9800 GT 512 MB Motherboard: Foxconn P45A-S LGA 775 Intel ATX RAM: Corsair 4 GB (2x 2GB) DDR2-800 (PC2 6400) Full specs: New PC 2008 Troubleshooting tried so far (the problem occurred again after taking each of these steps, one at a time): Updated the video drivers with the latest drivers from NVidia's site. Opened up the case and cleaned out the video card and processor fans (both were pretty dirty). Installed and ran temperature monitor software. The processor idles at about 50 degrees C, and goes up to about 63 degrees C while playing a game (seems on the warm side, but not excessively so?). The software wasn't able to report the temperature of the GPU -- not sure this particular GPU supports software temperature readout? My initial diagnosis is that maybe the GPU is on its last legs (given that it seems to be running pretty hot, and the problem only occurs while playing 3D games). Does this seem likely? Or is it likely that this problem is caused by the processor, RAM, or motherboard? Or could this be a software issue of some kind? Thanks for any advice!

• HP UX can not boot from Ignite Tape

  - by Spirit

  We have hp rp2470 server running hp-ux 11.00, with LVM mirroring. As for redundancy we have second rp2470 same hw (same two processors, same ram, same two hdd’s, same number of lan cards). I want to clone first one to the second. For that purpose I am making ignite tape with the following command: make_tape_recovery -x inc_entire=vg00 Ignite tape finishes without problems. When I boot second server from this ignate tape, server is starting to boot, and ignite restore finishes without any errors, only few notes, which are normal. However vmunix is not booting and when restore finishes, it boot to ISL prompt. From this I cannot boot /stand/vmunix. I tried to run recovery shell but no success. When recovery shell ask to do frecover to restore critical files, then I receive error: frecover(5405): unable to open /dev/rmt/0m At first I thought that the problem might be in the difference of the firmware version of the servers: fw version of production server is: Firmware Version 43.50 and fw version of backup server is: Firmware Version 42.19 So i did a fw upgrade of my backup server so that both servers are v43.50, and tried a recovery but again cant boot the system. Next I did another archive tape with -I (Interactive) flag: make_tape_recovery -I -x inc_entire=vg00 and tried recovery with it, again no good. I cannot find any error or warnings on ignite log, and I cannot boot hpux. I am only on ISL prompt. This is what i've noticed on the gsp logs: ************* SYSTEM ALERT ************** SYSTEM NAME: mcnfwim1 DATE: 07/27/2003 TIME: 10:18:49 ALERT LEVEL: 6 = Boot possible, pending failure - action required REASON FOR ALERT SOURCE: 8 = I/O SOURCE DETAIL: 6 = disk SOURCE ID: 0 PROBLEM DETAIL: 0 = no problem detail LEDs: RUN ATTENTION FAULT REMOTE POWER FLASH OFF ON ON ON LED State: Boot Failed.

• Is my Cisco switch port bad?

  - by ewwhite

  I've been chasing a packet-loss and network stability issue for a handful of end-users on an internal network for the past few days... These issues surfaced last week, however the location was struck by lightning six weeks ago. I was seeing 5-10% packet loss between a stack of four Cisco 2960's and several PC's and phones on the other side of a 77-meter run. The PC's were run inline with the phones over a trunked link (switchport configuration pastebin). We were seeing dropped calls and interruptions in client-server applications and Microsoft Exchange connectivity. I tried the usual troubleshooting steps remotely, having a local technician do the following during breaks in user and production activity: change cables between the wall jack and device. change patch cables between the patch panel and switch port(s). try different switch ports within the 2960 stack. change end-user devices with known-good equipment (new phones, different PC's). clear switch port interface counters and monitor incrementing errors closely. (Pastebin output of sh int) Pored over the device logs and Observium RRD graphs. No link up/down issues from the switch side. change power strips on the end-user side. test cable runs from the Cisco 2960 using test cable-diagnostics tdr int Gi4/0/9 (clean)* test cable runs with a Tripp-Lite cable tester. (clean) run diagnostics on the switch stack members. (clean) In the end, it took three changes of switch ports to find a stable solution. The only logical conclusion is that a few Cisco 2960 switch ports are bad or flaky... Not dead, but not consistent in behavior either. I'm not used to seeing individual ports die in this manner. What else can I test or check to determine if these devices are bad? Is it common for single ports to have problems, rather than a contiguous bank of ports? BTW - show cable-diagnostics tdr int Gi4/0/14 is very cool...

• IE and Google Chrome timeout on an IIS6 hosted SSL page that Firefox handles well

  - by Thomas

  Ok, here's the scenario: Up until a few weeks ago, none of us noticed anything wrong with the corporate website. People were using it without complaint. Then, a client complained that a specific page on the site was timing out for him, and only when he committed a POST action on a form filled with data. I checked it out, and it timed out for me, too. But, it only timed out in Google Chrome and IE, not in Firefox. Additionally, the same page, on the same server, but served from a different domain name (one not under the protection of SSL, either) does not time out under any browser. To clarify: https://www.mysite.com/changes.php times out on POST, but the same with http works fine. That distinction (SSL vs. Non-SSL) seems to be important, as nothing else has changed. Our certificate is valid, and Firefox detects no errors thrown by the page. I've looked at the Request and Response headers from the page, and they all follow the correct formats. Then, after wandering through the site, I noticed a few other things. Both IE and Chrome will frequently time out on any page that is PHP-based. They never time out on static images or html files. I've looked at the site from a variety of different servers, my home and work workstations, and my netbook. Because of that, I've discounted a viral infection, as I highly doubt a virus is going to hit every one of the machines to which I have access in exactly the same manner. My setup is: Server: Win2k3, II6, PHP 5.2.9-1. Clients: IE7, IE8, Chrome (regular and dev channel): Frequent timeouts on PHP pages. Firefox 2, Firefox 3: No timeouts. Firebug shows no errors or even lengthy periods serving the pages. I've spent 2 days searching for any tech knowledge that I can find, and my search parameters are all too general. Everyone has problems loading SSL pages in IE and Chrome for a wide variety of reasons. The infrequent nature of the timeouts and the fact that there are no errors being reported anywhere is starting to drive me insane. Does anyone have any insight on a problem like this?

• CakePHP in a subdirectory using nginx (Rewrite rules?)

  - by lhnz

  I managed to get this to work a while back, but on returning to the cakephp project I had started it seems that whatever changes I've made to nginx recently (or perhaps a recent update) have broken my rewrite rules. Currently I have: worker_processes 1; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; server { listen 80; server_name localhost; location / { root html; index index.php index.html index.htm; } location /basic_cake/ { index index.php; if (-f $request_filename) { break; } if (!-f $request_filename) { rewrite ^/basic_cake/(.+)$ /basic_cake/index.php?url=$1 last; break; } } location /cake_test/ { index index.php; if (-f $request_filename) { break; } if (!-f $request_filename) { rewrite ^/cake_test/(.+)$ /cake_test/index.php?url=$1 last; break; } } # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { root html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } server { listen 8081; server_name localhost; root /srv/http/html/xsp; location / { index index.html index.htm index.aspx default.aspx; } location ~ \.(aspx|asmx|ashx|asax|ascx|soap|rem|axd|cs|config|dll)$ { fastcgi_pass 127.0.0.1:9001; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } } The problem that I have is that the css and images will not load from the webroot. Instead if I visit http://localhost/basic_cake/css/cake.generic.css, I get a page which tells me: CakePHP: the rapid development php framework Missing Controller Error: CssController could not be found. Error: Create the class CssController below in file: app/controllers/css_controller.php var $name = 'Css'; } ? Notice: If you want to customize this error message, create app/views/errors/missing_controller.ctp CakePHP: the rapid development php framework Does anybody have any ideas on how to fix this?

• Changing Physical Path gives blank homepage

  - by Julie

  I have two websites ASP Classic - www.company.com and www.companytesting.com. At this time of year, company.com is pointed to a folder called website2012 and companytesting.com is pointing to a folder called website2013. The contents of those two folders are almost identical, just minor changes for our season change (which I was supposed to do today - lol). Up until a couple of weeks ago, I was running Windows Server 2003. To update the "live" website, I'd make a copy of the test site folder, and rename it website2013R1, and point the test site there, then point the live site at website2012. We now have Windows Server 2008 R2 64. (I had someone migrate the websites to the new server for me.) The companytesting.com site, when I pointed it to website2013R1, worked fine. The company.com site, when I pointed it to website2013 (which worked just before, for the companytesting.com site) gives an empty page. (i.e. view source = nothing there.) There is nothing in the failed request log when this happens. I can use the Explore button/link (upper right) in IIS7.5 and see all of the files there. If I use the browse button (either in general or on the index.asp page) I get the blank page again. One weirdness about how these are set up is that companytesting.com uses a login (which I think is windows authentication - it's simply a single username and password for staff, and to keep the GoogleBots out of it). Obviously, company.com does not. But redirecting the to website2013r1 kept the login in place. (So I'm not absolutely clear whether that's attached to the folder or to the site. Hitting the company.com site after changing the path did not yield a password request.) The permissions on the folders all seem to be the same, but obviously, I'm missing something. Why isn't changing the physical path working? As is probably obvious, I'm not knowledgeable about servers. I did OK in 2003, but since it's not my main task and I'm buried right now, I have barely looked at 2008. So I may have really stupid questions when you ask me to check something.

• iptables management tools for large scale environment

  - by womble

  The environment I'm operating in is a large-scale web hosting operation (several hundred servers under management, almost-all-public addressing, etc -- so anything that talks about managing ADSL links is unlikely to work well), and we're looking for something that will be comfortable managing both the core ruleset (around 12,000 entries in iptables at current count) plus the host-based rulesets we manage for customers. Our core router ruleset changes a few times a day, and the host-based rulesets would change maybe 50 times a month (across all the servers, so maybe one change per five servers per month). We're currently using filtergen (which is balls in general, and super-balls at our scale of operation), and I've used shorewall in the past at other jobs (which would be preferable to filtergen, but I figure there's got to be something out there that's better than that). The "musts" we've come up with for any replacement system are: Must generate a ruleset fairly quickly (a filtergen run on our ruleset takes 15-20 minutes; this is just insane) -- this is related to the next point: Must generate an iptables-restore style file and load that in one hit, not call iptables for every rule insert Must not take down the firewall for an extended period while the ruleset reloads (again, this is a consequence of the above point) Must support IPv6 (we aren't deploying anything new that isn't IPv6 compatible) Must be DFSG-free Must use plain-text configuration files (as we run everything through revision control, and using standard Unix text-manipulation tools are our SOP) Must support both RedHat and Debian (packaged preferred, but at the very least mustn't be overtly hostile to either distro's standards) Must support the ability to run arbitrary iptables commands to support features that aren't part of the system's "native language" Anything that doesn't meet all these criteria will not be considered. The following are our "nice to haves": Should support config file "fragments" (that is, you can drop a pile of files in a directory and say to the firewall "include everything in this directory in the ruleset"; we use configuration management extensively and would like to use this feature to provide service-specific rules automatically) Should support raw tables Should allow you to specify particular ICMP in both incoming packets and REJECT rules Should gracefully support hostnames that resolve to more than one IP address (we've been caught by this one a few times with filtergen; it's a rather royal pain in the butt) The more optional/weird iptables features that the tool supports (either natively or via existing or easily-writable plugins) the better. We use strange features of iptables now and then, and the more of those that "just work", the better for everyone.

• what is Remote Desktop Services in Windows Server 2008 R2 all about?

  - by fejesjoco

  Seriously, I'm lost in all that sales mumbo-jumbo. Let's say I want 1 or 2 users to be able to remotely log on to a server, run Word, Visual Studio, Firefox, and whatever. Do I gain anything at all if I install Remote Desktop Services? Or do I just install Desktop Experience feature pack, enable remote desktop and voila, nobody will ever notice the difference? Here's what TechNet says about Remote Desktop Session Host: A Remote Desktop Session Host (RD Session Host) server is the server that hosts Windows-based programs or the full Windows desktop for Remote Desktop Services clients. Users can connect to an RD Session Host server to run programs, to save files, and to use network resources on that server. Users can access an RD Session Host server by using Remote Desktop Connection or by using RemoteApp. The good old simple remote desktop can also host a full Windows desktop for remote clients so that they can run programs, save files and do all that stuff. Why do they write about it like it's such a great new invention, besides that they want to sell it? RDSH doesn't seem all that different at all. What do I install when I install RDSH, since all those features are already there in Windows? What's even more confusing is that you need to take special care when you want to install applications to an RDSH so that they will be usable by many concurrent users. Why? All the modern applications install the program files in one directory, store some common settings in the ProgramData folder and the HKLM hive, and store user specific settings in the Users folder and the HKCU hive. They are designed to be usable by many users on the same machine. 2 or 2000 users can use them concurrently without any efforts. I can sign in with 2 users to a server with only remote desktop enabled, and both of us can run Word or anything without any problems, can't we? So what changes if I set RDSH to install mode, or what happens if I don't? Why is the feature to switch between install and execute mode there at all? Yes I know of some advantages in Remote Desktop Services, like there's no 2 user limit, it supports virtualization, video acceleration and stuff, it has a whole infrastructure with gateway, web access, connection broker, etc. But I don't need those, so if you take these away, how are these two technologies different? From the articles it seems like they are completely different technologies, whereas it looks to me that they are completely the same at the core, and Remote Desktop Services just adds some additional features, but doesn't reinvent anything.

• Firefox: non-Vimperator way to do mouseless browsing?

  - by Peter Mortensen

  Is it possible to do efficient browsing with Firefox using only the keyboard (like in Opera)? By efficient I mean something faster than using TAB - this takes far too long. The arrow keys should be for navigation (in Opera it is Shift + arrow key). It can done with the Vimperator add-on, but isn't there a simpler way? Update 2: the closest to Opera's way is to enable caret navigation (F7 toggles this mode). It doesn't jump between links so it is a little bit slower, but the normal navigation (arrow keys, page up, page down, etc.) works and the focus/caret/cursor follows (in contrast to a text editor for page up/down). And text can be selected and copied like in a text editor. The biggest drawback is that in practice it is necessary to switch in and out of caret mode. And there is no indication of which mode is currently active. Update 1: a work-around (proposed by several but is not really what I am looking for) can be used if 3 settings are changed (to make it practical). After these changes the first few letters of a link text can be typed and that link will selected so pressing Enter will open it. Using the work-around the screen will jump around if it is a long page as it does not restrict itself to the current visible page, but it is usable. First settings change: menu Tools/Options/Advanced/tab General/Accessibility/Search for text when I start typing Turn this option on. Second settings change: set option to only go to links; in address bar enter: about:config followed by Enter. Then: press "I'll be careful, I promise", find the line accessibility.typeaheadfind.linksonly, select it and change the value to True by either hitting Enter or Shift+F10/Toggle (accessibility.typeaheadfind.linksonly is on line 11 when I tried). Third settings change: turn off case-sensitivity. Set accessibility.typeaheadfind.casesensitive to 0 (same procedure as for accessibility.typeaheadfind.linksonly, see above. When Enter is pressed a dialog box will appear with the current value. Type 0 and press Enter). To use: type some part of the link. If there are several possibilities use Ctrl+G (or F3) to jump between them. Use Ctrl+Enter to open in a new tab. Platform: Firefox 3.0.6, Windows XP 64 bit SP2.

• Samba share not accessible from Win 7 - tried advice on superuser

  - by Roy Grubb

  I have an old Red Hat Linux box that I use, amongst other things, to run Samba. My Vista and remaining Win XP PC can access the p/w-protected Samba shares. I just set up a new Windows 7 64-bit Pro PC. Attempts to access the Samba shares by clicking on the Linux box's icon in 'Network' from this machine gave a Logon failure: unknown user name or bad password. message when I gave the correct credentials. So I followed the suggestions in Windows 7, connecting to Samba shares (also checked here but found LmCompatibilityLevel was already 1). This got me a little further. If click on the Linux box's icon in 'Network' from this machine I now see icons for the shared directories. But when I click on one of these, I get \\LX\share is not accessible. You might not have permission... etc. I tried making the Win 7 password the same as my Samba p/w (the user name was already the same). Same result. The Linux box does part of what I need for ecommerce - the in-house part, it's not accessible to the Internet. As my Linux Fu is weak, I have to avoid changes to the Linux box, so I'm hoping someone can tell me what to do to Win 7 to make it behave like XP and Vista when accessing this share. Help please!? Thanks Thanks for replying @Randolph. I had set 'Network security: LAN Manager authentication level' to Send LM & NTLM - use NTLMv2 session security if negotiated based on the advice in Windows 7, connecting to Samba shares and had restarted the machine, but that didn't work for me. I'll try playing with other Network security values. I have now tried the following: Network security: Allow Local System to use computer identity for NTLM: changed from Not Defined to "Enabled". Restarted machine Still says "\LX\share is not accessible. You might not have permission..." etc. Network security: Restrict NTLM: Add remote server exceptions for NTLM Authentication (added LX) Restarted machine Still says "\LX\share is not accessible. You might not have permission..." etc. I can't see any other Network security settings that might affect this. Any other ideas please? Thanks Roy

• DNS settings for resolving Host name to IP not working?

  - by Hasas Ali Khan

  I want to access my IIS hosted application over LAN. First I installed a DNS server. The DNS configuration steps are: Go to DNS Manager - right click on System Name - click on configure a DNS Server. DNS Server wizard open -, click on next button - Select radio button "forward lookup zone" click on next button. In the second window. click on radio button "The server maintains the zone" and then click next. Give the zone name "example.com" Click on radio button, "Do Not allow dynamic updates". and then click next button. In the next window, click on radio button "No it should not forward query" and then click next button. Complete the configure a DNS server wizard and then click on finish button. After it is managing the DNS records: In DNS server wizard. open tree of forward lookup zone and right click on the new zone name "example.com" - properties and click on "Start of authority" and write values on text boxes serial number=1 primary server=systemname.domainname responsible person=hostmaster.domainname Click on server name, highlight domain name, click on edit button and enter IP address of the server where I host my application. Highlight new zone name and right click on it and click "New Host" option. In this window there are three text boxes: Name(user parent name if blank)=scoring Fully Qualified Domain Name=scoring.example.com IP Address= My IP Address and check on "Create associated pointer(PTR) record" and click on "Add Host" Host button and then click done button. I have host header for my application is "scoring" on port 80 and its working fine on server my application setting are I have change its, Advance setting --> Application Pool Identity --> Local System application can access on server with host name "scoring" but it can not access on machines on LAN. When I change LAN machine host file that is under, C:/windows/system32/driver/etc/host and edit it and enter host name with hosted machine IP like this: scoring 192.168.1.20 By making these changes I can run the application over LAN machines as I mentioned above DNS setting by which I can run App over LAN with out editing the client's host file. What mistake am I doing in this configuration?

• DVD playback with Windows Media Player 11 works fine, but when copied to HDD and then played back, t

  - by stakx

  I have several DVDs with short documentaries on it. Since the notebook I'm using (a Dell Latitude E6400) has only one DVD drive, and I might play back those short movies very often, I thought of copying them to the HDD and playing them back from there. However, I've run into a problem, namely stuttering audio. Problem description: When I play back these movies directly from DVD (with Windows Media Player 11 under Windows Vista), everything works fine. Smooth video, no significant audio problems (only the occasional click). But as soon as I copy any of these DVDs to the HDD and try to play them back from there (e.g. using the wmpdvd://drive/title/chapter?contentdir=path protocol, I get stuttering audio — audio playback sounds like a machine gun for a third of a second or so, approx. every 8 seconds. I have tried converting the VOB files from the DVD to another format (ie. ripping), but that resulted in a noticeable downgrade of picture quality. Therefore I thought it best to keep the files in their original format, if possible. Still, I suspect that the stuttering audio is due to some (de-)muxing problem, and that changing the file format might help. (After all, video playback is fine; therefore I don't think that the hardware is too slow for playback.) Only thing is, I don't know how to convert the VOB files to another Windows Media Player-compatible format without quality loss. I hope someone can help me, or give me further pointers on things I could try out to get HDD playback to work without the problem described. Some things I've tried so far, without any success: VOB2MPG, in order to convert the .vob file to a .mpg file. But that changes only the A/V container, not the content. No re-encoding takes place at all. Re-encoding with MPlayer/MEncoder. Lots of quality loss there, and I frankly haven't got the time to test all possible settings combinations available. Disabling all plug-ins, equalizers, etc. in Windows Media Player. Disabling all hardware acceleration on the audio playback device. Further info on the VOB files I'm trying to playback: The video format is MPEG ES, PAL 720x576 pixels @ 24/25 frames per second. The sound stream is uncompressed PCM, 16-bit stereo @ 48kHz. (Might it help if I somehow re-encoded the sound stream at a lower resolution, or as an MP3? If so, how would I do this without changing the video stream?) P.S.: I am limited to using Windows Media Player (11). (I previously tried MPlayer btw., but the video playback quality was surprisingly bad.)

• how does openvpn decide which interface to get IP addrs from

  Using ubuntu 10.04 on both ends. We have a client and server machine on the SAME network attempting to make a vpn connection. We use the config files from here and made minimal changes.

• Generating/managing config files for hosted application

  - by mfinni

  I asked a question about config management, and haven't seen a reply. It's possible my question was too vague, so let's get down to brass tacks. Here's the process we follow when onboarding a new customer instance into our hosted application : how would you manage this? I'm leaning towards a Perl script to populate templates to generate shell scripts, config files, XML config files, etc. Looking briefly at CFengine and Chef, it seems like they're not going to reduce the amount of work, because I'd still have to manually specify all of the changes/edits within the tool. Doesn't seem to be much of a gain over touching the config files directly. We add a stanza to the main config file for the core (3rd-party) application. This stanza has values that defines the instance (customer) name the TCP listener port for this instance (not one currently used) the DB2 database name (serial numeric identifier, already exists, they get prestaged for us by the DBAs) three sub-config files, by name - they need to be created from 3 templates and be named after the instance The sub-config files define: The filepath for the DB2 volumes The filepath for the storage of objects The filepath for just one of the DB2 volumes (yes, redundant to the first item. We run some application commands, start the instance We do some LDAP thingies (make an OU for the instance, etc.) We add a stanza to the config file for our security listener that acts as a passthrough to LDAP instance name LDAP OU TCP port for instance DB2 database name We restart the security listener (off-hours), change the main config file from item 1, stop and restart the instance. It is now authenticating via LDAP. We add the stop and start commands for this instance to the HA failover scripts. We import an XML config file into the instance that defines things for the actual application for the customer - user names, groups, permissions, and business rules. The XML is supplied by the implementation team. Now, we configure the dataloading application We add a stanza to the existing top-level config file that points to a new customer-level config file. The new customer-level config file includes: the instance (customer) name the DB2 database name arbitrary number of sub-config files, by name Each of the sub-config files defines: filepaths to the directories for ingestion, feedback, backup, and failure those filepaths have a common path to a customer-specific folder, and then one folder for each sub-config file Each of those filepaths needs to be created We need to add this customer instance to our monitoring scripts that confirm the proper processes are running and can be logged into. Of course, those monitoring config files include the instance name, the TCP port, the DB2 database name, etc. There's also a reporting application that needs to be configured for the new instance. You get the idea. There's also XML that is loaded into WAS by the middleware team. We give them the values for them to plug into the XML - they could very easily hand us the template and we could give them back completed XML.

• Missing startup screens and slow bootup/login after using WinClone to expand Bootcamp partition

  - by user26453

  I used WinClone to backup my Bootcamp partition, which was a Windows 7 Ultimate install, on my late 2006 Macbook Pro. I desired to expand the Bootcamp partition's size. It worked reasonably well with some hiccups along the way and some remaining issues. First issue I ran into was the Bootcamp Assistant utility - it would not recreate the partition. This was due to a lack of contiguous space that is required for the Bootcamp partition. As a result I wiped the whole drive and reinstalled Snow Leopard, did the minimum amount of system updates, and created and formated a new Bootcamp partition. WinClone restored the image without complaint and the image was automatically resized to the new partition's size. Second issue I ran into was after the first boot into Windows. The first thing I noticed was that instead of the newer "slick" startup screen (4 colors wisping around, a Windows 7 title), there was more of an old school style startup screen (a progress bar with block increments, yellow/greenish color, nothing else really). The initial bootup to a login screen was slow, perhaps as Windows dealt with the partition changes. After logging in, the screen goes blank and the computer seems to hang for a minute, before completing the login. After subsequent restarts, the slick screen is still missing, boot to login screen is normal, but the time from login to desktop active is still very slow. As a side note, this behavior of a long time from login to the desktop finally loaded I've previously only seen when the computer would try to hibernate and fail (battery is really bad). On the next startup, I would see this behavior, but not subsequently. So a potential cause: I imaged the partition after hibernating out of Windows. From reading some posts/guides on the subject, this was not recommended, and perhaps shouldn't even have worked? Could the partition be stuck in some weird mode as a result that makes the boot issues appear? I've attempted to disable hibernation and restart, trying to delete the .sys file that hibernation uses. Other fixes I'm thinking of attempting are booting a Win7 disc and repairing the install/partition. I can't shake the nagging feeling something isn't right as a result of the modified boot screens and the slow login process.

• MBPro, mid 2010 can't see Dlink DIR655 signal after sleep etc

  - by user88114

  This is my son's MBP 7,1 running Snow Leopard 10.6.7. Router signal is fine since iPad, Wintel on same table 20 feet from router are fine. the MBP however frequently wakes and fails to find the internet. iStumbler can see 1 neighbours hub and my garden hub are there but can't get to the normal DIR655 wifi... no ping no en0 or en1 device seems to exist. Airport off and on does not help. He just resets router and it all works but this does not please me! I must admit the winter sometimes seems to loose connect too, but less so. The DIR655 (hardware rev A3) is on the original EU firmware 1.10, I'm cautious about jumping to latest 1.31EU since no downgrade seems to be possible and that feels a bit risky as so much is set up and working fine. If I use the DIR655 admin web and release the lease the MBP has then wake it all worked OK. So I suspect lease timing/locking issue but unsure how to check up, plus why iStumbler seems to say the network is not visible at all when I sit on the iPad right next to it just fine.. I do not think there are any channel overlaps and we also have RFquiet DECT phones (Orchid) that are silent until lifted or called. Anyway signals all show low interference and high throughput except for this failure to connect. Just walked the MBP to the garden office and iStumbler now sees the more distant DIR655 signal although it will not connect to it (does not show under Sys Prefs NetNetwork names) even after airport off & on... It also refuses to connect to my garden network (an old Belkin acting as AP wired to DIR655), the signal it can see and even net name in Sys Prefs NetNetwork names (2 mins later):NOW both names ARE visible, but both fail to accept the correct WPA2 password and keep asking again after failing to connect. IT ALL MAKES NO SENSE TO ME. Just revoked the lease for the MBP on DIR655 and no changes although this seemed to help MBP wake into connection 1 hour ago. OK a bit of walking about to report. Carried MBP across garden towards DIR655, a few other wifis show up on iStumbler, low signals all channel 1. Right next to DIR655 but iStumbler not showing it, although most other wifi's have gone. I'd say iStubler is suffering timeouts&hangs but hard to be sure. Lots of attempts to Airport on/off, join other etc and suddenly I get to connect, get given new IP (I revoked), can browse. Walk away, connection drops quite soon at 30 feet then reconnected briefly then died again. MUST ATTEND ELSEWHERE FOR A BIT...

• Hang while starting several daemons

  - by Adrian Lang

  I’m running a Debian Squeeze AMD64 server. Target runlevel after boot is runlevel 2, which includes rsyslogd, cron, sshd and some other stuff, but not dovecot, postfix, apache2, etc. The system fails to reach runlevel 2 with several symptoms: The system hangs at trying to start rsyslogd Booting into runlevel 1 works, then login from the console works Starting rsyslogd from runlevel 1 via /etc/init.d/rsyslog hangs Starting runlevel 2 with rsyslogd disabled works But then, logging in via console fails: I get the motd, and then nothing Starting sshd from runlevel 1 succeeds But then, I cannot login via ssh. Sometimes password ssh login gives me the motd and then nothing, sometimes not even this. Trying to offer a public key seems to annoy the sshd enough to not talk to me any further. When rebooting from runlevel 1, the server hangs at trying to stop apache2 (which is not running, so this really should be trivial). Trying to stop apache2 when logged in in runleve 1 does hang as well. And that’s just the stuff which fails all the time. RAM has been tested, dmesg shows no problems. I have no clue. Update: (shortened) output from rsyslogd -c4 -d called in runlevel 1 rsyslogd 4.6.4 startup, compatibility mode 4, module path '' caller requested object 'net', not found (iRet -3003) Requested to load module 'lmnet' loading module '/user/lib/rsyslog/lmnet.so' module of type 2 being loaded conf.c requested ref for 'lmnet', refcount 1 rsylog runtime initialized, version 4.6.4, current users 1 syslogd.c requested ref for 'lmnet', refcount now 2 I can kill rsyslogd with Strg+C, then. /var/log shows none of the configured log files, though. Update2: Thanks to @DerfK I still have no clue, but at least I narrowed down the problem. I’m now testing with /etc/init.d/apache2 stop (without an apache2 running, of course) which hangs as well and looks like an even more obvious failure. After some testing I found out that a file with one single line: /usr/sbin/apache2ctl configtest /dev/null 2&1 hangs, while the same line executed in an interactive shell works. I was not able to further reduce this line while, i. e. every single part, the stream redirections and the commando itself is necessary to reproduce the hang. @DerfK also pointed me to strace which gave a shallow hint about what kind of hang we have here: wait4(-1for the init scripts futex(0xsomepointer, FUTEX_WAIT_PRIVATE, 2, NULL for rsyslogd / apache2 binaries called by the init scripts The system was installed as a Debian Lenny by my hoster in autumn 2011, I upgraded it to Squeeze immediately and kept it up to date with Squeeze, which then used to be testing. There were no big changes, though. I guess I never tried to reboot the system before.

• Why do some games randomly turn my screen a random solid color?

  - by Emlena.PhD

  When playing some games my computer will randomly have an error that I cannot fix without turning it off and back on again. The screen changes to one solid color, which varies (off the top of my head I can remember seeing solid green, magenta, etc..) and the sound blares a single tone. The sound sometimes briefly restores and I can still hear the game sounds and even hear and still be heard by people in my Mumble channel, but the screen doesn't right itself so I'm still blind. What's more is this happens in some games but not in others. While the game is actually running, not while I'm still in the menu. However, it does happen if I'm afk or idle but the game world is still rendering. Games where the error occurs: League of Legends World of Warcraft Trine The Sims 2 Dungeon Defenders Safe games: games where it has never occurred: Tribes: Ascend Star Wars: the Old Republic Battlefield 3 So relatively older games cause the problem while newer games do not? I cannot predict when it will happen, it just seems random. However, if it happens and I try playing the same game further after restart it does appear to occur more frequently after the first time. But if I switch to a safe game it doesn't continue happening. Both of my RAM sticks appear fine, flipped position or either one on their own and games still run, computer still boots. I would think over-heating, but then why not all games? ALso, sometimes it happens immediately after I start playing, within seconds of the 3D world booting up. I'm looking to upgrade very soon so I want to figure out what component or software is fubar and replace/repair it. Any suggestions or recommendations of tools would be helpful. Below is some system information. Dxdiag does not detect any problems.

• Local Apache on Windows XP not finishing page requests

  - by asgeo1

  I have Apache 2.2.11 installed locally on my Windows XP (SP3) dev machine, which I setup about 3 months ago. I have just started having a strange problem in the last few week. Apache is serving some basic PHP applications like phpMyAdmin. When I make a page request, Apache appears to not finish serving all resources for that page. Firefox shows the "Transferring data from servername..." message, and the page never completes. The same problem happens in Internet Explorer too. I can sometimes tell which resource it is waiting on, because most of the page will render except for some image or similar resources. (Not sure why Firebug doesn't show this) It doesn't have the problem every page request - for page requests where most of the resources are cached in my browser, the page request will work with no problems. Or pages that are very light will work with no problems. However, if I "hard" refresh the page, I will have this problem (probably because it is requesting all page resources) Does anyone know what this could be? It is so strange that it has only just started happening - and I did not make any changes to my system (that I am aware of) I tried playing with the Apache ThreadsPerChild setting, but it did not seem to make a difference. UPDATE: I have been doing some more tests. I have been serving the most basic of pages, just a plain HTML file: <html> <body> <h1>testing</h1> </body> </html> If I request this page multiple times in a row, AND each request occurs immediately after the previous has completed, then 50% of the time the request will time out. However, if I put a 1-2 second gap between requests, then there is no problem. This correlates to what I have observed when the brower requests a real application page. When the browser has nothing cached, then all of the page resources are requested from the browser in a short amount of time - this appears to trigger the problem. UPDATE2: Nathan Long has helped me understand the issue a little better with the server-status page (see below). It is weird, it is like the server has a hickup sending data to the client. The client sits there waiting forever for data that never arrives. Closing the client process does not terminate the connection on the server - the server still has active threads for each previously attempted connection, but they just sit there - not sending any data and never terminating. (even though the client is now closed) Only a restart of the server seems to terminate them.

• Windows 2008 IIS 7.0 HTTP to HTTPS Redirect -- Versus IIS 6.0 Mechanism

  - by Dan7el

  This topic, creating a mechanism for redirection from HTTP to HTTPS on a Windows 2008 server running IIS 7.0 is a much written-about topic on the Internet. How this is done is really not so much my issue. My issue is more of explaining why this can't be done with the standard HTTP Redirect module that ships with Windows 2008 IIS 7.0. Instead, there are other methods needed that are more arduous. First, the IIS 6.0 method requires no externally available modules nor does it require any additional modifications to the web.config or any type of other development effort. It's outlined here: http://blogs.microsoft.co.il/blogs/dorr/archive/2009/01/13/how-to-force-redirection-from-http-to-https-on-iis-6-0.aspx And, you can see the basic steps are to run the snap-in, get the properties on the site, and do some modifications. Presto, you have the HTTP -- HTTP redirect setup. Now, on the IIS 7.0 platform, it doesn't seem this simple. An initial search found the following site: http://www.sslshopper.com/iis7-redirect-http-to-https.html Which has two separate approcates: 1. Involves installing a separately available Microsoft module -- URL Rewrite Module, and then adding XML to the web.config. 2. Custom Error Page. ...there might be other methods, but these are the basic ones and the first is listed as the primary method. But wait...There exists on the IIS 7.0 an HTTP Redirect Module. So...why can't I use the HTTP Redirect Module to do this very thing? This is really my big question. I need to know this because my management is going to insist I use the HTTP Redirect Module and set up the HTTP to HTTPS redirect in a similar fashion to how we do in IIS 6.0. Can someone please explain to me, in clean, simple, easy to understand, terms that both I and my management can understand as to why I need to go get the URL Rewrite Module and install that on the server and make the web.config changes suggested by the article instead of simply using the HTTP Redirect module that's already installed on the site? Thanks a bunch.

• Hot-swap drive got new name, can I change it on-the-fly?

  - by T.J. Crowder

  One of the HDDs in my server's RAID config failed, so I took it out of the array and had the data center hot-swap it. They've done that, but now the new drive is /dev/sdc rather than /dev/sda. I suspect — correct me if I'm wrong — that if I reboot the server, it will be /dev/sda again, so I'm hesitant to add it back to the array as /dev/sdc because I don't want to lay a trap for myself to fall into on the next reboot. I'd just as soon not reboot the server if I don't need to (if I do need to, well, too bad for me). Is there a way I can change the device name from /dev/sdc to /dev/sda without rebooting? This is on Ubuntu 10.04 LTS. It's an md array ("Linux Software RAID"), where currently one of the devices (there are a couple of them) looks like this ("degraded" because I've removed the old /dev/sda from it): # mdadm --detail /dev/md0 /dev/md0: Version : 00.90.03 Creation Time : Sun Oct 11 21:07:54 2009 Raid Level : raid1 Array Size : 97536 (95.27 MiB 99.88 MB) Used Dev Size : 97536 (95.27 MiB 99.88 MB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 0 Persistence : Superblock is persistent Update Time : Thu Jun 30 09:31:16 2011 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 UUID : 496be7a5:ab9177ed:7792c71e:7dc17aa4 Events : 0.112 Number Major Minor RaidDevice State 0 8 17 0 active sync /dev/sdb1 1 0 0 1 removed Thanks, Update: Reading through the kernel md documentation, I suspect that if the name changes on reboot, it won't matter. (Good design, that.) Here's why: Boot time autodetection of RAID arrays When md is compiled into the kernel (not as module), partitions of type 0xfd are scanned and automatically assembled into RAID arrays. This autodetection may be suppressed with the kernel parameter "raid=noautodetect". As of kernel 2.6.9, only drives with a type 0 superblock can be autodetected and run at boot time. The kernel parameter "raid=partitionable" (or "raid=part") means that all auto-detected arrays are assembled as partitionable. I do have md compiled into the kernel, so I'm rebuilding the array now and will do the reboot to see what happens. Even if it works, the above doesn't answer the question I actually asked, so unless someone comes along and answers that question in the meantime (I'd be interested, even if it's not necessary for what I'm doing this very moment), I'll just delete the question to keep noise down.

• High load on X3220 Quad Core Linux Apache server

  - by John Templar

  I'm seriously in need of help. My sites are now nearly impossible to use because of massive loads on my server. I'm already a month late on my mortgage and this really isn't helping my situation. I've been working on fixing this intermittent load problem for months (never this bad). I'm suspecting some kind of attack since I'm under DDOS attack a lot! I've been trying to figure out what is causing the load but I'm afraid I just don't have the experience or knowledge to understand all the data I've been looking at. I don't even know where to begin or how to test for the large array of attacks out there. Here's some data you might find useful... Server: Xeon X3220 Quad Core 2.4 GHz - Linux, FreeBSD 500 GB HD and 8 Gig of Ram. Runs Centos release 5.7 Server Version: Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 mod_qos/9.74 Warning: All sites are softcore adult sites - mostly fantasy art like elves and amazons. 1) Sites may run fine for weeks or just days at less than 10 load then start jumping to 40-80 load - no idea why. Same sites, same mods, same amount of traffic - just WHAM! 2) I get an email almost every day that says: "Large Number of Failed Login Attempts from IP (different each time)". My webhost (who almost never helps me) told me it was a udp flood or something. 3) I've changed the port for MySQL from the default. If I ever put it back to the default - I get Loads of over 100 from what must be a constant mysql port flood. 4) I've reconfigured MYSQL.

I've spent a couple weeks turning all the mods/plugins off, waiting a day and then turning them back on the next day or later if there isn't any change (there hasn't been). For example, on Thursday I'll turn off videos, on Friday I'll turn off chat.. etc and nothing changes the load appreciably. 6) Joomla info: All SEF turned off - sh404sef completely disabled and removed.

• Mixed sessions with Classic ASP on IIS 7.5 and Windows 2008 R2 64 bit

  - by Marcin

  Recently had an issues with a server upgrade from IIS 6 on Windows 2003 to IIS 7.5 on Windows 2008 R2 64 bit. We have a number of websites running on Classic ASP. All the sites sit under a particular site, e.g. www.example.com/foo and www.example.com/foobar. On IIS 6 each site was set up as a virtual directory and things worked fine. Since moving to the new set up, a lot of websites seem to have mixed Sessions. To be clear, this is not a app pool recycling issue; rather the sessions are populated with information when the user hits the site and while browsing they get sessions from different sites. We've determined this based on - a few customers called up and reported having their shopping cart with items with names of items belonging to a different site - also our own testing showed that some queries being run would try to bring products in from a different site We've tried - disabling dynamic caching - converting each site to be a virtual application (if I understand correctly, the virtual directory/application concepts were changed/refined somewhat in IIS 7 although to be honest, I'm not clear what the difference is) - various application pool changes (using .NET 2 framework), classic and integrated modes, changing the Process model to NetworkIdentity), all to no avail. The only thing we haven't tried is changing it to run as a 32 bit application. We're not using http only cookies, so when I open up a browser and type document.cookie into the dev console in Firefox/Chrome/IE that there will be multiple ASPSESSIONID=... values whereas previously I believe there was only one. Finally, we use server side JScript for the classic ASP pages, not VBScript, so we have code similar to the below. //the user's login account as a jscript object Session("user") = { email : "[email protected]", id : 123 }; and if we execute a line of code like below: Response.Write( typeof(Session("user")) ); When things are running correctly, we get "object" - as expected. When the Session gets trashed, the output is "unknown" and we are also unable to access the fields within the JScript object (e.g. the .email or .id fields). Much appreciated if anyone can provide any pointers about how to resolve this, everything on google seems to point to different issues.
