• What is the sysadmin's dream network printer? 6-8k pg/mo. Xerox, OkiData, Lexmark and HP are all fail

  - by Jacob

  How do I find out what printer brand and/or type doesn't suck? This information is hard to find and manufacturer's websites won't reveal any issues with certain printers. After 10 years of dealing with network shared printers, I can't say that I have been impressed with any of the printer brands I've seen. Brother's little laser MFPs have been close to ideal for low volume, but that is it, period. OkiData, Lexmark, HP, Xerox solid ink printers, they all sucked in one way or another. Currently I'm looking to replace a Xerox ColorQube 8570 because it fails to print on a regular basis. Sometimes it doesn't even boot VxWorks fully - it just hangs at 2% or whatever. I've used Xerox 8860MFPs and they sucked just as bad. I won't talk about ink jets here, that's most likely not what I'm looking for. We currently spend about $4k on paper and ink per year for this printer at up to 6-8k pages per month, letter, mostly black and white, low color usage. I want the printer to feed paper correctly, not crash and burn when a PDF isn't according to its taste (my favorite Xerox problem here) and with decent drivers for Windows and OS X. Print quality is not of the utmost importance but paper does get sent to customers.

• .NET 2.0 Application now running slow on IIS 7.5

  - by Valien

  I recently moved (and still in testing) an application from a Windows 2003 Server (Physical box) running IIS 6.x to a Windows 2008 R2 Standard (VM) IIS 7.5 server. The application is a .NET framework 2.0 application and is running under a 2.0 App Pool. This site works great except for one thing: Takes forever to get a request back. I've been tracking it with Chrome Inspect Element and it queries the site and can take up to 45 seconds to answer. Now when it does the page(s) render instantly but it's that initial request that's killing it. I see no error logs or issues with the application or Windows Event Viewer or even IIS logs so not sure where to start looking next. Some new changes was that previously the app resided behind a Pix firewall and now is behind a larger network environment in a DMZ zone (and I believe NetScaler is also being used to manage the network). I do not have rights/abilities to look at the network itself but can contact the Data center folks to look deeper into this but I wanted to make sure it's not my application that might be causing the slowdown or IIS. In summary: .NET 2.0 application works great in IIS 6.x Application moved to an IIS 7.5 server and now slow on rendering but when it does render responds back with pages instantly. Edit for solution Found out that it was the SOAP calls that were slowing the site down. In the new datacenter my application cannot request SOAP calls and so they time out after 40-45 seconds or so. Now trying to find out if I can install a proxy server to redirect this...

• Tridion 2011 SP1 Core Service - expose to live server within PROD env

  - by Neil

  We have a requirement to allow our users to submit information about their "projects" - a small piece of text and single image they upload. Ultimately we'll have a listing page of user contributed projects that others can comment on and rate. We've decided to user Tridion's UGC for rating & comments site-wide for this first phase which has got me thinking - UGC is tied to Tridion published pages & components, if we want UGC on our user-submitted projects, they'll have to be created within Tridion as components themselves, not be sat in some custom db table? Is this where the Core Service could come in? My understanding is that the CD Web Service is for retrieval, not for interacting with the Content Manager. Is it OK (!) architecturally to expose the Core Service only to our live application servers so our backend .NET code can create "project components" that can be then be published by editors allowing them to be commented on? Everything sounds pretty neat and tidy apart from the "exposing Core Service to live servers" bit. Without this though I'd have to write a custom way to "transfer" it back over to the Content Manager - maybe like Audience Manager Sync works? Anyone done this before?

• Site hanging in iis7 - how do I troubleshoot?

  - by Chris Foot

  I am currently having a problem with a windows 2008 server running IIS 7. The server runs several sites but only seems to have the issue with one particular site. Every so often, the whole server slows to a crawl with nearly all requests timing out! Invariably, when we log in to take a look there is always an IIS process using up around 90% cpu. Looking into the worker processes in IIS there are usually one or two requests that have been running for a long time. They are always in the ExecuteRequestHandler state with ManagedPipeline as the module name and the current ones i'm looking at have been running for 7686248 (what units is this in, it doesn't say?). It is also not always the same page, in fact we have seen at least 3 different pages listed under url when this has happened. It seems that the only way to bring the server back to life is to kill the 90% process! The site is running under .Net 4.0 and the code on it is very similar to other sites on the server which do not have the problem! How do I start troubleshooting this?

• Free software for backing up an attached network drive

  - by Richard

  My wireless router comes with a USB connector which allows me to plug an external hard drive in and it'll act as a Network Attached Storage. The problem is that I want to backup this hard-drive to the external drive of another computer so that if the NAS drive fails, I don't lose everything. However, Windows 7 Backup refuses to include the NAS as a location to backup. I can't fool it by mapping it to a drive letter either. Google presents lots of pages on how to backup files to a NAS, but not the other way around. Can anyone advise me on free software which can do incremental backups of a NAS drive to an external drive attached the computer it is running on? I'm aware of this question but the top answers have one or more of the following issues: They aren't free. The free version cannot backup a NAS. They cannot do incremental backups. They're just a script and therefore have limited other functionality (eg. disk space management, scheduling, compression, etc.etc.)

• Disadvantages of enabling 'Low Fragmentation Heap' LFH on Windows Server 2003?

  - by James Wiseman

  I've been investigating an issue with a production Classic ASP website running on IIS6 which seems indicative of memory fragmentation. One of the suggestions of how to ameliorate this came from Stackoverflow: How can I find why some classic asp pages randomly take a real long time to execute?. It suggested flipping a setting in the site's global.asa file to 'turn on' Low Fragmentation Heap (LFH). The following code (with a registered version of the accompanying DLL) did the trick. Set LFHObj=CreateObject("TURNONLFH.ObjTurnOnLFH") LFHObj.TurnOnLFH() application("TurnOnLFHResult")=CStr(LFHObj.TurnOnLFHResult) (Really the code isn't that important to the question). An author of a linked post reported a seemingly magic resolution to this issue, and, reading around a little more, I discovered that this setting is enabled by default on Windows Server 2008. So, naturally, this left me a little concerned: Why is this setting not enabled by default on 2003, or If it works in 2008 why have Microsoft not issued a patch to enable it by default on 2003? I suspect the answer to the above is the same for both (if there is one). Obviously, we're testing it in a non-production environment, and doing an array of metrics and comparisons to deem if it does help us. But aside from this I'm really just trying to understand if there's any technical reason why we should do this, or if there are any gotchas that we need to be aware of.

• Preventing DDOS/SYN attacks (as far as possible)

  - by Godius

  Recently my CENTOS machine has been under many attacks. I run MRTG and the TCP connections graph shoots up like crazy when an attack is going on. It results in the machine becoming inaccessible. My MRTG graph: mrtg graph This is my current /etc/sysctl.conf config # Kernel sysctl configuration file for Red Hat Linux # # For binary values, 0 is disabled, 1 is enabled.

Im no expert, but im not sure if this is ideal. My question is, what are some good things to add to the iptables file and possibly other files which would make it harder for the attackers to attack my machine without closing out any non-attacking users. Thanks in advance!

• URL Redirect Configuration in Virtualhost for a Single Page Web Application

  - by fenderplayer

  I have a web application under development that I am running locally. The home page of the application is fetched with the following url: http://local.dev/myapp/index.shtml When the app runs, javascript on the webpage maintains the url and the app state internally. Some of the other urls read as: http://local.dev/myapp/results?param1=val1&param2=val2 http://local.dev/myapp/someResource Note that there are no pages named results.html or someResource.html on my web server. They are just made up URLs to simulate RESTfulness in the single page app. All the app code - javascript, css etc - is present in the index.shtml file So, essentially, the question is how can I redirect all requests to the first URL above? Here's how the vhost configuration looks like: <VirtualHost 0.0.0.0:80> ServerAdmin [email protected] DocumentRoot "/Users/Me/mySites" ServerName local.dev RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(myapp|myapp2)\/results\?.+$ $1/index.shtml [R=301,L] <Directory "/Users/Me/mySites/"> Options +Includes Indexes MultiViews FollowSymlinks AllowOverride All Order allow,deny Allow from all </Directory> ErrorLog "/private/var/log/apache2/error.log" CustomLog "/private/var/log/apache2/access.log" common </VirtualHost> But this doesn't seem to work. Requesting the other URLs directly results in 404 error.

• Varnish returning 503, FetchError (could not get storage)

  - by Archan

  On the current setup we're running into a problem with Varnish, we're running a CentOS 5.7 x86_64 xenpv, with Cpanel WHM, hosted at VPS.net. Sometimes we will recieve a Guru Meditation from Varnish, and when we look in the varnishlog with the following command varnishlog -d -c -m TxStatus:503 it returns output similar to the following: 15 VCL_call c recv 15 VCL_acl c NO_MATCH devs 15 VCL_return c pass 15 VCL_call c hash 15 Hash c **** 15 Hash c ************* 15 VCL_return c hash 15 VCL_call c pass pass 15 Backend c 12 default default 15 TTL c 1835862523 RFC 0 -1 -1 1332454056 0 1332454055 375007920 0 15 VCL_call c fetch hit_for_pass 15 ObjProtocol c HTTP/1.1 15 ObjResponse c OK 15 ObjHeader c Date: Thu, 22 Mar 2012 22:07:35 GMT 15 ObjHeader c Server: Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_bwlimited/1.4 mod_fcgid/2.3.6 15 ObjHeader c X-Powered-By: PHP/5.3.9 15 ObjHeader c Expires: Thu, 19 Nov 1981 08:52:00 GMT 15 ObjHeader c Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0 15 ObjHeader c Pragma: no-cache 15 ObjHeader c Content-Type: text/html; charset=utf-8 15 ObjHeader c X-Cacheable: NO:Cache-Control=private 15 FetchError c chunked read_error: 12 (Could not get storage) 15 VCL_call c error deliver 15 VCL_call c deliver deliver As far as I have could gather, we could try increasing the nuke_limit, but currently we have a nuke_limit of 500, and when running varnishstat -1 -f n_lru_nuked we "only" get a total of 1031, even though we have seen the error happen on several pages. When we then run top to see how much memory Varnish is using, it only shows that it is using 763m, although we've set it to be allowed to use 1200m. Any ideas of what the problem can be?

• Visual Studio 2010 won't compile/create new projects

  - by tuner

  My Visual Studio 2010 Professional with SP1 installed won't compile anymore. The shown error is: TRACKER : error TRK0005: Failed to locate: "CL.exe". The system cannot find the file specified. Strangely it is also not possible anymore to create new projects - the wizard appears but just restarts when I press create. As I found out the paths for Visual Studio are now built from settings in the registry. Namely HKEY_CURRENT_USER\Software\Microsoft\VisualStudio. Comparing a colleagues installation with mine revealed no different settings. So this is how the Property Pages/Configuration Properties/VC++ Directories look like: Executable Directories: $(ExecutablePath) Include Directories: $(IncludePath) Reference Directories: $(ReferencePath) Library Directories: $(LibraryPath) Source Directories: $(SourcePath) Exclude Directories: $(ExcludePath) From the Visual Studio 2010 Command Prompt, cl.exe is found. I can only guess that this behavior was caused by a reinstallation of Studio a couple of months ago (to a different folder). As we use an external build-script for our main project there is a good chance that it is broken since then. Any hints?

• Loading a big database dump into PostgreSQL using cat

  - by RussH

  I have a pair of very large (~17 GB) database dumps that I want to load into postgresql 9.3. After installing the database packages, learning more or less how to use them, and fiddling around a little on various StackExchange pages (particularly this question), it looks like a proper command for me to use is something like: cat mydb.pgdump | psql mydb because of the format the dump is in. My machine has 16 GB of RAM, and I'm not familiar with the cat command but I do know that my RAM is 99% exhausted and the database is taking a while to load. My machine isn't non-responsive to the point of hanging; I can run other commands in other terminal windows and have them execute at a reasonable clip, but I am wondering if cat is the best way to pipe in the file or if something else is more efficient? My concern is that maybe cat could be using up all the RAM so the database doesn't have much to work with, throttling its performance. But I'm new to thinking about RAM issues like this and don't know if I'm worrying about nothing. Now that I think about it, this seems to be more of a question about cat and its memory usage than anything else. If there is a more appropriate forum for this question please let me know. Thanks!

• Redirect 301 fails with a path as destination

  - by Martijn Heemels

  I'm using a large number of Redirect 301's which are suddenly failing on a new webserver. We're in pre-production tests on the new webserver, prior to migrating the sites, but some sites are failing with 500 Internal Server Error. The content, both databases and files, are mirrored from the old to the new server, so we can test if all sites work properly. I traced this problem to mod_alias' Redirect statement, which is used from .htaccess to redirect visitors and search engines from old content to new pages. Apparently the Apache server requires the destination to be a full url, including protocol and hostname. Redirect 301 /directory/ /target/ # Not Valid Redirect 301 /main.html / # Not Valid Redirect 301 /directory/ http://www.example.com/target/ # Valid Redirect 301 /main.html http://www.example.com/ # Valid This contradicts the Apache documentation for Apache 2.2, which states: The new URL should be an absolute URL beginning with a scheme and hostname, but a URL-path beginning with a slash may also be used, in which case the scheme and hostname of the current server will be added. Of course I verified that we're using Apache 2.2 on both the old and the new server. The old server is a Gentoo box with Apache 2.2.11, while the new one is a RHEL 5 box with Apache 2.2.3. The workaround would be to change all paths to full URL's, or to convert the statements to mod_rewrite rules, but I'd prefer the documented behaviour. What are your experiences?

• Deploying ASP.NET MVC to Windows Server 2003

  - by pete the pagan-gerbil

  Hi, I have a problem with an MVC 2 website on Windows Server 2003 running IIS 6. It is externally hosted, but we have a 2003 server internally for testing. The internal server runs the website fine, the external server gives a 403 ("website declined to show this page") error when navigating to the root of the site, and a 404 if I try to navigate directly to a page resource. I have tried the wildcard ISAPI mapping and extension mapping, and a couple of other common checks (I forget exactly which now, most of them were already set correctly), but so far no joy. All the settings can be replicated on our internal server and the pages return properly. IIS logs just show exactly what the browser shows - 404 errors and 403s. I've read about a different level of trust required for an MVC application compared to a WebForms application - how can I check permissions and trust levels on the external and internal servers (assuming I am able to check that) and if that would cause these errors, what are the minimum levels that MVC require? Failing that, what else might be causing this error for me to try out?

• The Wifi is working fine but no internet connection in Windows 8 [migrated]

  - by Ali

  I'm currently having a Problem with my msi GT70 laptop. my laptop is running windows 8 and yesterday it requested a Restart to Update. after the Restart and the update I tried to surf the net through google chrome, the WiFi connection is perfect but the page I tried to access is not loading at all, after a while it shows failure to load page. I disabled and reenabled the WiFi chip through the device manager but still no internet connection. I uninstalled and reinstalled the drivers, still no internet. I updated the Driver of the wifi, still no internet, I even went to Wifi configuration and tried to change the DNS and reset it back to automatically, still no Luck.. I'm really lost I don't know what to do, I don't want to go deep and play with Laptop DNA "aka: registry file" and screw things up. I really appreciate any help in this matter. thanks in advance. Note: I tried to access many pages but no luck. I even tried Firefox, Opera, even ie still no luck. The internet is working fine on my tablet and cellphone, except for the Laptop.

• VirtualBox VM running web server not accessible via external IP

  - by mwigdahl

  I have a Windows 7 machine running VirtualBox with an Ubuntu guest. The guest has a Bitnami LAMP stack installed. I have the guest configured for Bridged networking, and I can access the guest web server just fine from other machines on my LAN using the guest's IP. I'm trying to configure port forwarding so that I can access the web server from outside my LAN. (The router is a 2WIRE model as I'm on ATT's UVerse). I've set up port forwarding for ports 80 and 443 to the guest's IP in a similar manner to how I had them set up for my previous, physical web server, which worked just fine. However, I cannot seem to access the new, virtual web server using my external IP on the forwarded port. I suspected Windows Firewall issues on the host, but disabling it didn't solve the issue. Anyone have advice on what I should try next? EDIT: I've now attempted disabling the firewall on the guest with sudo ufw disable -- that doesn't seem to help either. However, after checking the router's port forwarding in more detail I may see the problem. My VM is named "linux" and in the router's configuration pages it shows up inconsistently. Sometimes it reports with a valid LAN IP and other times it doesn't show up with any IP. Even when it shows the correct IP the router indicates that it is disconnected. Could this be an indication that the 2WIRE router doesn't play well with VirtualBox's bridged networking mode?

• How can I safely close this window and forever avoid seeing similar pop-ups from Mackeeper Zeobit's malware and spyware?

  - by Michael Prescott

  The attached image shows a window that just popped up and the only button available is the OK button. I could Force quit Safari, but I've got several sites open right now and don't want to try and find my place again. Besides, I've seen similar hacks in the past and I'd like to learn how to handle them in a way better than just a brute force-quit. I've never heard of MacKeeper or Zeobit, so I opened Firefox and did a few searches while Safari is obviously still stuck, waiting for me to click the sneaky OK button in the dialog window. Anyhow, at least the first few pages of most search results contain lots of blabbering from questionable witnesses about how MacKeeper saved them from some malware or spyware. However, any company that is hacking the browser to maliciously install their product is itself the criminal and not providing a true security application. So, there are three questions here: How can I close this window? Can I do something to Safari to avoid these hacks in the future? (Just curious) Is MacKeeper or Zeobit somehow loading the search results so that no information about their application being malware or spyware is listed (I can't be the only person in the world that is offended by their tactics, even though it appears I am)?

• nginx reverse proxy to apache mod_wsgi doesn't work

• Using my own Postfix, filtering spam and getting all the mail into my ISP's inbox

  - by djechelon

  Hello, I currently own a domain bought via GoDaddy.com, which provides me a basic email setup for the most common needs. I configured it to forward all mail to [email protected] to [email protected]. I also own a virtual server with a running Postfix that I use for a specific website (all mail to somedomain.com gets forwarded via LMTP to a program written by me). Since I'm recently experiencing some harassing by spammers, since GoDaddy doesn't seem to filter spam, and since my Windows Phone's Pocket Outlook cannot filter spam, I would like to use SpamAssassin to filter inbound spam by changing my domain's MX records to my server My ideal setup is the following: All mail delivered to somedomain.com gets redirected via LMTP as usual via virtual transport without any spam check All mail to [email protected] gets redirected to [email protected] after a severe spam check I don't care about [email protected] since I use just one address for now I would like to train SpamAssassin with customized spam rules, possibly based on the presence of certain keywords (links to certain unsubscribe pages I found recurring) I currently configured Postfix with transport somedomain.com lmtp:[127.0.0.1]:8025 .somedomain.com error: Cannot accept mail for this domain relay somedomain.com OK (I guess I should add mydomain.com OK too) virtual @mydomain.com [email protected] (looks like a catch-all rule, it's OK as requirement 3) I installed SpamAssassin, I can do rcspamd start and set it to boot with the server, but I don't know if there is anything else to do for use in Postfix, and how to apply requirement 1 (only mail to mydomain.com gets filtered) I also tried to send an email via Telnet to make sure my settings are ready for MX change. I received the message into my account but I found that it gone through secureserver.net, like Postfix didn't rewrite the destination but simply relayed the message. Thank you in advance. I'm no expert in SpamAssassin, and I have little experience in Postfix (enough to avoid making my server an open relay)

• Selectively allow unsafe html tags in Plone

  - by dhill

  I'm searching for a way to put widgets from several services (PicasaWeb, Yahoo Pipes, Delicious bookmarks, etc.) on the community site I host on Plone (currently 3.2.1). I'm looking for a way to allow a group of users to use dangerous html tags. There are some ways I see, but I don't know how to implement those. One would be changing safe_html for the pages editors own (1). Another would be to allow those tags on some subtree (2). And yet another finding an equivalent of "static text portlet" that would display in the middle panel (3). We could then use some of the composite products (I stumbled upon Collage and CMFContentPanels), to include the unsafe content on other sites. My site has been ridden by advert bots, so I don't want to remove the filtering all together. I don't have an easy (no false positives) way of checking which users are bots, so deploying captcha now wouldn't help either. The question is: How to implement any of those solutions? (I already asked that on plone mailing list without an answer, so I thought I would give it another try here.)

• Understanding RedHats recommended tuned profiles

  - by espenfjo

  We are going to roll out tuned (and numad) on ~1000 servers, the majority of them being VMware servers either on NetApp or 3Par storage. According to RedHats documentation we should choose the virtual-guestprofile. What it is doing can be seen here: tuned.conf We are changing the IO scheduler to NOOP as both VMware and the NetApp/3Par should do sufficient scheduling for us. However, after investigating a bit I am not sure why they are increasing vm.dirty_ratio and kernel.sched_min_granularity_ns. As far as I have understood increasing increasing vm.dirty_ratio to 40% will mean that for a server with 20GB ram, 8GB can be dirty at any given time unless vm.dirty_writeback_centisecsis hit first. And while flushing these 8GB all IO for the application will be blocked until the dirty pages are freed. Increasing the dirty_ratio would probably mean higher write performance at peaks as we now have a larger cache, but then again when the cache fills IO will be blocked for a considerably longer time (Several seconds). The other is why they are increasing the sched_min_granularity_ns. If I understand it correctly increasing this value will decrease the number of time slices per epoch(sched_latency_ns) meaning that running tasks will get more time to finish their work. I can understand this being a very good thing for applications with very few threads, but for eg. apache or other processes with a lot of threads would this not be counter-productive?

• Daisychain external USB drive to WD My Book World Edition (Blue rings)

  - by d03boy

  I recently bought a new My Book Essential 1TB (WDBACW0010HBK-NESN) to daisychain to my older My Book World Edition 500GB (blue rings) with one of the version 01.xx.xx firmwares. At first when I connected the USB drive to the MBWE, it showed up in the System Summary section of the administration page without any issue. I was able to set up a new share on the new drive. The administration website moved very, very slow though. The administration pages became nearly unresponsive during this setup process. Once the share was set up I could access the new share but again, it was very slow, now through Windows Explorer. I looked around the internet and it seems that this is caused by the USB drive being formatted with NTFS. I tried reformatting it (again, as NTFS) just to double check and the same problem occurred. I then tried FAT32 but realized it would only support files of approximately 2GB and that is not acceptable for me. I decided to try a firmware upgrade on the MBWE to version 02.00.19. The firmware upgrade completed successfully but now the MBWE does not display the USB drive in the System Summary like it did with the earlier firmware version. The USB drive works perfectly fine when connected directly to my computer. Is there a way to solve this issue?

• Block users from Social networking websites while firewall is down

  - by SuperFurryToad

  We currently have a SonicWall firewall, which does a pretty good job a blocking Social networking websites like Facebook and Bebo. The problem we are having is that sometimes we need to temporarily disable our firewall blocklist so we can update our company's page on Facebook for example. Whenever we do this, have see an avalanche of users logging on to their Facebook pages during work time. So what we need a way to block access while the firewall is down. For the sake of argument, we have two groups of users - "management" and "standard users". "standard users" would have no access to Facebook, but "management" users would have access. Perhaps something like a host file redirect for non-management users. This could probably be enforced via group policy that would call a bat file to copy down the host file, depending if the user was management or not. I'm keen to hear any suggestions for what the best practice would be for this in a Windows/AD environment. Yes, I know what we're doing here is trying to solve a HR problem using IT. But this is the way management wants it and we have a lot of semi-autonomous branch offices that we don't have a lot of day to day contact with, so an automated way of enforcing this would be the most preferable method.

• Problem Uninstalling Microsoft Internet Explorer

  - by Roger F. Gay

  On Windows Vista Home Premium (x64) I am trying to uninstall Microsoft Internet Explorer. The procedures explained all over the web involve going through the control panel to Programs and Features. If MSIE is listed there, then uninstall in the usual way. If it is not listed there, click Turn Windows features on and off and deactivate it there. But Internet Explorer is not listed in either place. Background: I initiated some process in MSIE a couple of months ago that caused all web pages to no longer save login information or remain logged in when requested. As you can tell from the way I described that, I don't remember what it was and have no way to simply reverse it. I had a few problems with .NET Framework as well. So, I've uninstalled all browsers except MSIE and uninstalled .NET Framework. I've reinstalled .NET Framework and all other browsers. I have not been able to uninstall MSIE. Have Tried: I tried installing over the existing installation, but auto-update must be keeping it nicely up to date. The attempt simply produced an information window telling me that my current version is more up-to-date than the new version I tried to install.

• 'Bug in Mailman version 2.1.12'

  - by davorg

  I'm working on setting up a server running Plesk 10.4.4 Update #13 on Centos 6.2. I've configured Mailman and now I want to set up some mailing lists. I've created a list in the Plesk control panel, but when I try to administer the new list (by visiting http://lists.[domain].com/mailman/admin/[listname] I see the following error: Bug in Mailman version 2.1.12 We're sorry, we hit a bug! Please inform the webmaster for this site of this problem. Printing of traceback and other system information has been explicitly inhibited, but the webmaster can find this information in the Mailman error logs. I see exactly the same error if I try to go to the list info page at http://lists.[domain].com/mailman/listinfo/[listname]. I would follow the instructions and look in the error logs, but I can't find them. I would expect to find a file at /var/log/mailman/error, but there's nothing there. My test list seems to work correctly. It sends all the expected email. It's just the web pages for the list that seem to be broken. Has anyone else seen this? Any suggestions for tracking down and fixing the problem? p.s. I think I've chosen the correct Stack Exchange site, but it this question would be better asked elsewhere, please let me know. Update: I got to the bottom of this, so I'm documenting the answer in case anyone else has the same problem. The fact that I couldn't find the error log was the clue. The problem was that the Mailman process didn't have permissions to create an error log. And it seems that if Mailman can't create an error log then it will respond to any web request with this error page. Creating an error log file (in /var/log/mailman/error) and giving it the correct permissions fixed the problem.

• Linux wireless disconnect every 20 minutes

  - by james

  My laptop uses CentOS 6.3 with kernel 2.6.32-279.el6.x86_64. My wireless adaptor is Intel Corporation Centrino Wireless-N 1000. My wireless connection always get off after about 20 minutes. The network applet shows the connection is still on with good signal strength, but I just cannot load any web pages even the configuration page of the wireless router. The problem will continue until I disable and reconnect the wireless. Other devices like my cell phone uses the same wireless network without the problem. Even yesterday I'm using the same laptop with Fedora 17 without this problem. I also searched the internet and someone said running services NetworkManager and network simultaneously may be a problem. But I cannot stop any one of them because: if I stop network and start NetworkManager, the network service will start automatically; if I stop NetworkManager and run network, it says "Device does not seem to be present, delaying initialization." when trying to bringing on the wireless. What shall I do to get rid of the problem? Thank you very much!
