• Building an Email server for mass emails

  - by EGHDK

  I recently started doing IT odd jobs for a company. The company has a pretty decent sized mail list that costs them over $3000 per month to send out email from. The company is set on creating their own email server so that it can just run and send emails to the client lists. They only send out emails roughly once a month. Has anyone had experience with this? This wouldn't be an email server I guess (as it doesn't need to handle incoming messages) It just has to be able to send around 200,000 emails, once a month. What would be the best way to go about this? Services online like MailChimp have proved to be too pricey. It's not an ad that is being sent out, it's more of a monthly newsletter, so we don't need any crazy software for ROI or anything crazy like that. If I could fit 200,000 people in GMAIL, I'd do it, but I don't think I can (heh... maybe I should try).

• Using NFS for scalable PHP/MySQL web application

  - by Jeroen Moons

  Here's the situation: I have a PHP/MySQL web application that accepts user uploads (pdf files). From these pdf files' pages a preview image is made on the fly and presented to the web app's users. Some pdfs might be on the large side, most will be under 50 MB but some extreme cases could be as large as a few hundred MB. A little waiting for the preview image for large pdf files is acceptable but no more than a minute let's say. Everything is running on one server for now, but soon the app will hit the server's limit on both storage and processing power. My idea to solve the problem: To deal with this situation I had the idea of having one or more pdf processing servers as needed, and one or more file storage servers. These two types of servers are mounted to the server on which the actual app runs using NFS. The app could then use GearMan to delegate pdf processing tasks to these processing servers. The processing server can mount the storage server and read the file stored there, process it and write its output to that server. The servers I'm talking about will be amazon ec2 instances. The web app returns a link to the resulting pdf preview image on the storage server that was used which can then be used on the front end to show the image to the user. My question: I have zero experience with apps that use multiple servers, is this idea viable or is there a better way to do it? Is an NFS setup fast and reliable enough for this situation?

• a VPS mail server

  - by microspino

  Hello I'm trying to substitute citadel on my Virtual Private Server with something more simple. I dislike their documentation and the webmail client. I don't need any groupware feature. I need only an MTA with a nice looking web interface, SPAM and VIRUS check. I recently found the lamson project from Zed Shaw. Is that production ready? Do you had any real and good experience with It? On the latest-news page I see that the last release dates december 2009. Sorry for my lack of knowledge, I'm really new to mail servers but I have to find a solution to manage sending and receiving mail on my VPS. I would accept also to build my VPS email server using a linux system like exim, postfix or whatever but I have really small needs and they will not grow in at least a year and i will be the only one user. I'm searching for something that I could build and manage easily, as I'm a novice linux sysadmin. Having also some good documentation or at least a robust step by step guide would be a plus.

• Affordable combined Ruby/Rails/Redmine + Subversion hosting?

  - by Pekka

  I'm a self employed web developer and after nine years of hard work, I'm looking to become a bit more "vagrant" starting next year, do some much-needed traveling and a bit and work off and on, making use of one of the greatest advantages of a programming job: The ability to work virtually from everywhere. For that, I am looking for a reliable hosting company I can entrust my code to in the form of a number of Subversion repositories, and an installation of the Redmine project management tool. As my financial situation may vary during traveling, I am looking for something I can pay up front for a year or two, and is obviously not too pricey. I don't care where the company is located, as long as it's trustworthy and solid, meaning it's not likely to go out of business next month. Does anybody know good recommendations? Preferably from own, personal, good experience. I have looked at CVSDude / Codesion and while they are certainly great, they don't offer Redmine of course, and seem to be aiming toward bigger organizations mainly. What I would need: 2-5 Gigs of space minimum, freely distributable between SVN, and Redmine attachments Unlimited number of Subversion projects Access control (team members / checkout-only accounts / etc.) I don't mind configuring the svn settings on file basis myself I need the possibility to map a custom domain to the package that is hosted elsewhere Frequent backups and access to those backups through FTP or other means I have been running my own virtual server for this until now, but I don't want the hassle, especially on the security side, while I may not always have the internet connection to fix problems that may come up.

• How to debug silent hang on shutdown of Solaris 10?

  - by jblaine

  We're experiencing a mysterious hang on shutdown of a newly-imaged Oracle/Sun Solaris 10 SPARC box. It is repeatable (in the same spot ... from what we can tell). We let it try to work itself out multiple times for 5-10 minutes and it never progressed. I've never seen this happen before. The last thing displayed on the console is that syslogd was sent signal 15. Prior to us disabling snmpdx on the box, the last thing on the console was that snmpdx was sent signal 15 (after syslogd was sent signal 15). While very rare to find, in Solaris days past, I'd have a better idea from experience where the problem might be, and could then narrow things down further with silly (but effective) debugging echo statments in /etc/*.d scripts. With SMF in the picture, I'm not really quite sure where to start. We forced a crash dump via sync at the {ok} prompt for later analysis, and then let the box come up because it's a production server and our scheduled outage window was closing. /var/adm/messages shows nothing of use. How would you debug this situation? mdb ps of the savecore shows the following processes were running at hang time (afsd is the OpenAFS client and that many are expected): > > ::ps S PID PPID PGID SID UID FLAGS ADDR NAME R 0 0 0 0 0 0x00000001 00000000018387c0 sched R 108 0 0 0 0 0x00020001 00000600110fe010 zpool-silmaril-p R 3 0 0 0 0 0x00020001 0000060010b29848 fsflush R 2 0 0 0 0 0x00020001 0000060010b2a468 pageout R 1 0 0 0 0 0x4a024000 0000060010b2b088 init R 1327 1 1327 329 0 0x4a024002 00000600176ab0c0 reboot R 747 1 7 7 0 0x42020001 0000060017f9d0e0 afsd R 749 1 7 7 0 0x42020001 00000600180104d0 afsd R 752 1 7 7 0 0x42020001 0000060017cb44b8 afsd R 754 1 7 7 0 0x42020001 0000060017fc8068 afsd R 756 1 7 7 0 0x42020001 0000060017fcb0e8 afsd R 760 1 7 7 0 0x42020001 00000600177f4048 afsd R 762 1 7 7 0 0x42020001 000006001800f8b0 afsd R 764 1 7 7 0 0x42020001 000006001800ec90 afsd R 378 1 378 378 0 0x42020000 0000060013aee480 inetd R 7 1 7 7 0 0x42020000 0000060010b28008 svc.startd R 329 7 329 329 0 0x4a024000 00000600110ff850 sh Z 317 7 317 317 0 0x4a014002 0000060013b3a490 sac

• How to set up mysql storage for certain rsyslog input matches?

  - by ylluminate

  I'm draining various logs from Heroku to an rsyslog linux (ubuntu) server and am starting to have a little more to bite off than I can chew in terms of working with my log histories. I am needing to be able drill back in time based on more flexible details and more flexible access than what the standard syslog file(s) provide. I'm thinking that logging to mysql may be the correct approach, but how do I set this up such that it pulls only certain log entries into a table based on an identified? For example, I see a long hex string identifying each log entry from a certain Heroku app instance. I assume that I can just pipe those into the mysql socket vs ALL rsyslog input into mysql... Could someone please direct me to a resource that can walk me through the process of setting something like this up or simply provide some details that can help? I have 15+ years of Unix experience so I just need some nudging in the right direction as I've not really done a tremendous amount of work with syslog daemons previously in terms of pooling various servers into one. Additionally, I'd be interested in any log review tools that could make drilling through log arrangements like this more handy for developers.

• illegitimate traffic from user agent Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729)

  - by user114293

  Since the beginning of the year, I'm getting a lot of traffic with the user agent Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 (.NET CLR 3.5.30729). My access logs show 40% - 60% from that user agent. That's strange because the user agent states a Firefox 3.0.10 browser (is anybody using that browser in 2012? Definitely not 40%-60% of visitors on a normal website). Also, the logs show that this user agent only requested the HTML document and no referenced assets like images, css, js files. I checked the IPs of those requests (with that UA). It's coming from all over the world. I recognized that those IPs sometimes have a mobile user agent. So my suspicion is a mobile app that is doing a lot of "spider requests" - but if that would be the case than other web sites should have the same problem. That's actually my question: Does anybody experience same/similar problems?

• Windows 7 BSOD when changing power plan

  - by dd5

  i have a strange problem. When i want to change the power plan on my laptop from High performance to Balanced, Windows freezes and i get bsod. The power plan settings are all default. Laptop specs: - Intel Core i3 330M/350M - Intel® HM55 Express Chipset - DDR3 1066 MHz SDRAM 8GB - ATI Mobility™ Radeon HD5730 1GB DDR3 VRAM - Intel SSD330 128gb - Windows 7 Home premium I've searched the internets but couldnt find a similar issue. BSOD first started when i installed this SSD and stopped when i've updated the chipset controller driver then started again yesterday when i wanted to change the power settings plan.Minidump file here. Any help with this weird issue appriciated, thanks. Edit: - i've ran Memory diagnostic tool, - Intel SSD diagnostics - and updated the firmware to 3.2.1. Non of these steps worked or shown signs of errors - but still got BSOD when changing power plan settings. After analizing the dump file via osronline.com here a first few lines: CRITICAL_OBJECT_TERMINATION (f4) A process or thread crucial to system operation has unexpectedly exited or been terminated. Several processes and threads are necessary for the operation of the system; when they are terminated (for any reason), the system can no longer function.

• Windows 7 BSOD when I walk away from the computer

  - by bobobobo

  I have a really weird experience with this new AM3 box I set up. Everything seems fine at first. But now I get frequent (daily) BSOD's, mostly when I walk away from the computer for more than 5 minutes (when the computer is idle). The BSOD's as shown by BlueScreenView almost always have to do with ntoskrnl.exe, and they'll do with really normal sounding operations, like SYSTEM_SERVICE_EXCEPTION, NTFS_FILE_SYSTEM, DRIVER_IRQL_NOT_LESS_OR_EQUAL, KMODE_EXCEPTION_NOT_HANDLED, BAD_POOL_HEADER - You name it. These are basically them, and they repeat after that, just random order. Its not like one is more consistently the problem than the other. I have Windows update ON and I let it do its updates everytime it wants to. I turned windows indexing service off, but it seems Windows 7 does a lot of background processing when I'm away - I'll come into the room and the fan will be going nuts (I'm pretty sure this isn't because the computer flies into a panic whenever I leave). I tried finding updates for my ASUS, and really there isn't much to install (except some new driver firmware). I'm going to install that to see if it helps, but what else could it be? Is it possible its a hardware issue with the board? Or is every Windows 7 user experiencing daily BSOD these days that I don't know about?

• Determine wifi capabilities of Windows box (with WSUS install rules)

  - by Hagen von Eitzen

  I need to determine if a computer is in fact a laptop with wifi capabilities (with emphasis on wifi rather than laptop). More precisely, I want to distribute a piece of software I wrote via WSUS and Local Update Publisher to those clients. To this end, I want to create appropriate "Package installable rules", that is simple rule used bay the Windows Update Service on the client to decide beforehand whether or not an update/installation package is applicable. Typically, such "installabel rules" are logical combinations of rules of type "File exists", "Registry Key exists", "WMI Query", "MSI Product Installed", so I'd prefer one of those methods. The method I hope someone here can help me find should work with Win 7/Vista, preferably also with XP. My guess is that WMI query is the way to go, but I have little experience in that. I have found that one can e.g. query for EnclosureType and that might detect a laptop. However, I would be much happier if an actually available wifi interface would be detected. Does anyone have an idea how to approach this? If there is anything you need me to clarify, don't hesitate to comment.

• How do you notice that the batteries of you wireless mouse are dying out?

  - by hkBattousai

  I have a Logitech M705 wireless mouse. I'm first time using a wireless mouse, so I don't have much experience with the hardware features and behavior. It is rated that it runs for 3 years with the same batteries. I think this "3 year" rating is calculated for a very low usage and activity; like 2 hours a day. I'm using it for about 12 hours a day, so I expect it to run out of batteries in a much shorter time in my case. I have been using it for about half a year. Recently (for the last two weeks), it started to make some peculiar behavior when clicking and drafging objects. - When I click something, it sometimes double click it. - When I drag something from one place to another (or selecting some text), it sometimes drops the object in the halfway (when selecting text, the text which had selected up to that time becomes unselected and it starts to select the rest of the text from that moment), but it goes on being in the "left-button-pressed" state. It is like, the pressed button switches to "unpressed" state for a moment, then returns back to the "pressed" state. When one of these faults occur, it occurs several times sequentially. There is no problem in pointer movement, scrolling or right-clicking. Since the batteries last for a very long time for this device, I don't expect it to stop working in an instance. I expect it to give these kind of syndromes of a time period. My question is; Is this how batteries run out for a wireless mouse? Or, is this another kind of hardware/software problem?

• Compaq motherboard CQ60 AMD - nvidia chipsed graphic problem

  - by Dritan

  Hi! It nice to have read that you solved this problem this way. I have 2 laptops Compaq CQ60 AMD Athlon with Nvidia graphic cards. the first one is new, when i press power button, it lights up only the ON led in front and nothing else, no fan working, blank screen, no beep.. I don't know what may be the problem. When I put on power adaptor, it lights up only the side power led near dhe power adapter plug but it doesn't light up the front led one. the second one have this problem that it spins the fan, light power and On led, but it doesn't show nothing on the screen blank (even with external monitor). In this case it maybe this problem of the Nvida Graphic Chip and it may need a reflow. I have an hot air station, but I don't know if I should try this or the oven one. Please can you give me any suggestion what to do to solve this. I have read that the solution of the Oven method is just temporary,maximum of three months, do you have the same experience about this? Any suggestion is wellcome.

• How to organize deployment process in Chef-controlled environment?

  - by Alex

  I have a web Linux-based infrastructure which consists of 15 virtual machines and over 50 various services. It is fully controlled by Chef. Most of the services are developed internally. Basically the current deployment process is triggered by a shell script. A build system (a mix of Python and shell scripts) packages the services as .deb files and puts these packages into a repo. It runs apt-get update on all 15 nodes then because the standard Chef apt cookbook only runs apt-get once per day and we definitely do not want to run apt-get update unconditionally on each chef-client wake. The build system restarts chef-client daemons on all 15 nodes finally (we need this step because of pull Chef nature). The current process has a number of drawbacks we want to address. First off, it is asynchronous because the deployment script does not check chef-client logs after restart so we don't even know if the deployment was successful. It does not even wait for Chef clients to complete the cycle. Second, we definitely do not want to force chef-client restarts on all nodes because we usually deploy only a small number of packages. And third, I am not quite sure using chef-client for deployment is legitimate, probably we are just doing it wrong from the start. Please share your thoughts/experience.

• Setting up MySQL Linux slave with a Windows master

  - by philwilks

  I'm running a MySQL 5.0 database server on Windows Server 2008. The total size of the database is about 1Gb. I make daily backups, but I'd like to step up to having a slave server for extra protection. My thinking was that I wouldn't need the expense of a Windows machine to do this, and a Linux "cloud server" from RackSpace would do the job well for quite a low cost. However I have little experience with Linux, so I have a few questions... Does this sound like a good idea? Is there anything wrong with linking Windows and Linux MySQL servers? Does Linux have the equivalent of Remote Desktop Connection? If so can I use this from a Windows machine? Would a particular Linux distro be well suited to this task? RackSpace offer ArchLinux, CentOS, Debian, Fedora and Ubuntu. My immediate thinking is to go with Ubuntu as I've heard it's more friendly for people coming from a Windows background. Any comments you have would be very appreciated! Phil

• Legalities of freelance security consultant (SQLi) [closed]

  - by Seidr

  Over the years I've gained a large amount of experience in Programming (my main occupation) and server admin, and as a result have a fairly decent backing in security practices. I'm also pretty good at spotting security flaws in software (including but not limited to SQLi), and have built up a list of sites that could definately use some looking at. My question is, what are the legalities of me contacting these sites saying something along the lines of "I've looked at your site and it appears vulnerable - customer data could be compromoised - would you like me to fix it?". Could me finding out that the site is infact vulnerable be construed as an attack itself? If the prospective client so wished, could they take me to court over this? When I find a vulnerable site, all I do is confirm and make a note of the vulnerability. I'm not in it for personal gain (getting paid for FIXING it would be nice!), just curiosity. Is this a viable way to go about finding clients for this kind of work, or would you recommend a more 'legitimate' way? Any suggestions/advice would be greatly appreciated :)

• Which upgrade path for disk IO bound postgres server?

  - by user41679

  Hi all, We currently have a Sun x4270 with 2xquad core Xeon Nehalmen 2.93ghz cores (16 threads), 72 gig of ram and 16 x 10k SAS disks split between the os raid 1, a partition for the Write Ahead Logs which is raid 10 and a partition for the database tables and indexes which is also raid 10, all xfs. I'm currently evaluating which path to go down in terms of upgrades. We'll be sharding the DB at some point soon, but for now I need to focus on hardware upgrades specifically. The machine is not CPU or memory bound at all at the moment, just IOWait is become an issue. The machine is mostly write access as we have a heavy caching layer. We're seeing about 300 write IOPS average on both the database partitions. We don't have any additional storage infrastructure like a Fiber Channel or ISCSI network. Budget isn't too much of a concern, something inline with the size of this server (i.e no $1m IBM machines) Space is ok on the DB side of things, we're running out obviously but there's also some reduction we can do. Additional space would be good though. My current thoughts are either: * ISCSI SAN, possible with 10Gbit network that has solid state acceleration. * FusionIO card / Sun F20 card (will the FusionIO card work in the Sun box? * DAS shelf (something like this http://www.broadberry.co.uk/das-direct-attached-storage-servers/cyberstore-224s-das) which a combination of 15k sas disks and some Intel X25-E drives for DB indexes etc) what would I need to put in the x4270 to add a DAS shelf? I think it's a SAS HBA card, do I have to use Sun's own card or will any PCI Express card work? Anything else??? what would you guys do from your experience? I appreciate it's a lot of questions, but I haven't expanded a DB machine for a number of years and the landscape has changed dramatically since then! Any advice or feedback would be very much appreciated. Let me know if there's anything else I can clarify. Thanks in advance!

• Is the APC BR700G UPS (or similar) compatible with Active PFC power supplies?

  - by David Zaslavsky

  I'm looking at getting a UPS for my home computer. So far the APC BR700G looks very promising, except for one thing: one of the reviews on Newegg says that this UPS does not work with a power supply with Active PFC. Pros: Unit looks great, built well, very heavy, was excited to use it. Cons: Didn't research enough - many newer power supplies like my corsair 750w (and yes dells and other mainstreamers sell them too) that I bought last year have a feature called active pfc (power factor corrected). The signal for this backup battery doesn't fully support that feature and can cause issues. You can find an article on APCs site if you search their user forums for PFC. And the power supply in my computer is, in fact, an Active PFC PSU. I've already found one answer on this site claiming that it's not an issue, that "most quality supplies these days have PFC and work just fine with a UPS." That disagrees with the review on Newegg. Can someone explain this discrepancy? Also, what is it exactly about a UPS that makes it incompatible with an Active PFC PSU? (if anything) Is there some way to tell based on the technical specifications, or do I just have to hunt for reviews online to avoid wasting my money? While any input would be appreciated, I would prefer to get an answer from someone with actual experience with similar UPS's and Active PFC power supplies, who can tell me whether it works or not.

• Not getting IP from ISP on Multicast Network

  - by Johan Nielsen

  Im having an odd issue with my ISP (COMX.dk) I have a managed access gateway box (Telsay) with three 8P8C ports for use with Internet and Ip-Tv (respectively on different VLANS (so does my ISP tell me)) To utilize a port you will need to register your device's mac address through an online interface. You will then get your device paired with a static ip. I am using one port actively and I have registered another device (router). The router is configured to listen for an active dhcpd on the network. When my router get a lease I get a private ip 192.168.2.2 (not the one bound to my mac) which is odd! I unconnected my router from the gateway and connected my laptop directly. Same thing happened - I was given a private address. I did a port scan on the gateway and found port 80 to be open and browsed to the ip. I was then presented with a management interface of a Belkin wireless router (HMMM!!!!) <--by the way, not my gear At this point I called the ISP to let them know of my issue/findings - Only to be replied "Well, we cant see any rogue dhcp servers" (thinking to myself, well I can) I then decided that it could be fun to try the other port of my gateway, only to experience the same. So I reconnected my router and used the remaining port to make an observer(wireshark promic etc.) I am able to see my router trying to discover a dhcp server but I can also see my ISP's IGMP and PIMv2 packages just repeating the same pattern. Hello...Hello...Hello :) So I called them again, only to get the same response, "we dont see any rogue dhcp's...we cant see the host you are talking to (mac address of the Belkin router)...you are definitively connected through wireless?!?(no im not, no such thing as a wireless wire - i thought to myself)" My questions is, What is going on? (besides from what im reporting here) What am I seeing that the don't? What can I tell them in order for them to resolve mine/their issue?

• Running multiple copies of openssh-server (sshd) on Ubuntu

  - by cecilkorik

  I may be attacking this problem the wrong way, if so let me know. I have a server which is available through SSH from both the public internet and the local LAN. I would like to have two very different security policies for each, by running two copies of sshd with two different sshd_config files each on a different port. Some of the things I'd like to change is to allow password or public-key authentication on the LAN, but public-key only from the internet. All (real) users could login from the LAN side, but only certain authorized users would be individually whitelisted to login through the internet. As far as I can tell this requires having two different SSH daemons running on different ports with different sshd_configs. I am fine with the different ports part, I can easily forward port 22 to any port I want through my firewall. So my question is what is the best way to actually START the second sshd under Ubuntu 10.04 LTS. Is there a recommended way to do something like this? Surely I am not the first person with this sort of need. I have a bit of experience with upstart, and I can manually hack the second sshd into /etc/init/ssh.conf I suppose but I'm not sure if that will get overwritten by the package. However I do it, It's important to ensure both sshd processes always get restarted after any automatic or manual upgrade of the openssh-server package. Thanks in advance.

• Good references to know why has my computers stopped responding me

  - by Peterstone

  Hello all! I´m a windows xp user (but not for much time...) and I usually see how my computer stop of responding me. The process is this: Firsly it became totally stopped or very slow for certain periods of 5 minutes. How could I do? After that it gets stopped (Even not totally because If I click on the bar I see a blinking response in the bar botton of the program I click on. It´s could be anything related with security (like the firewall or some virus)? Computer university: I usually experience this, using Matlab (R2007a) with System Generator (its respective compatible version) My personal laptop: It´s usually works well but when stopped periods became to appears I know in not much time it will became totally stopped. I usually see how Word 2007 get stopped and after a while my windows xp gets stopped. (well I can access to the the manage task pressing ctr+alt and...).

• Mavericks permission issues with Windows Server deduplicated shares

  - by dmohlmaster

  We have a number of 10.9-10.9.3 - Mavericks - machines installed throughout our facility. Much of the user content is pulled from shares stored on our Windows Server 2012 fileservers with deduplication enabled. I have found that files newly written or unoptimized are able to be accessed without issue - read, written, modified, etc. Once the file gets optomized/deduplicated and Windows adds the P & L attributes - sparse and symlink - the Macs running Mavericks begin to have access issues. Once the files get deduplicated, users begin receiving read access errors when copying files (see error1 below). This happens when copying to folders within the current folder tree or copying somewhere to the local system. If you 'stop' the copy operation and retry a few more times, it may eventually work for the specific instance but fail again later. I am however, able to copy these files without issue via the terminal. Other systems running 10.7 do not experience the same issues and are able to access file server resources without issue. Many of the systems having issues are newer and thus not able to be downgraded to 10.8 or 10.7. I have tried finder replacements such as Pathfinder but the results are the same. I know this is at least similar to the issues many Mac users are already experiencing and posting about but I haven't seen it directly linked to deduplication and the attributes written by Windows server. Has anyone seen this issue? Have any solutions been found? Error 1: When copying files after the PL attributes have been set by deduplication. "One or more items can't be copied to "Foler" because you don't have permissions to read them. ******************************************' Via the system.log, I am also seeing the following error when accessing these deduplicated file shares. The reparse point tag listed below is "IO_REPARSE_TAG_DEDUP" Reported error: "smbfs_nget: filename.ext - unknown reparse point tag 0x80000013"

• GNU Screen and Finch Not Playing Nicely

  - by Sean M

  I use finch for instant messaging, and for persistence, finch is one of the things that runs in my screen session. There are three main computers that I access my screen session from, and each works at a different screen resolution. Because of the different resolutions, when I switch computers, I use screen -rd to attach to my screen session. Using screen -x results in problems. When I attach to the session, though, finch experiences display problems. I have to wait up to several minutes for finch to become responsive - it doesn't redraw properly at all. Trying to switch between chats just writes ^n and ^p, or ^(1-9) for numbers. It fixes itself after some time. Using ctrl-l does not help. Switching back and forth between screen windows does not help. This is an annoying behavior that I don't experience with any other applications running in screen. Is this a bug in screen or finch, and if not, what can I change about my configuration to correct it ? (would appreciate it if "finch" could be used as a tag for this instead of or in addition to "pidgin")

• Forcing users to change password on first login - Windows Server 2008 R2 Remote Desktop Services

  - by George Durzi

  I'm setting up a demo lab environment in which each demo lab user is assigned 4 accounts to use in the lab. Users access the lab via Remote Desktop to the "client" machine in the lab - exposed at demolab.mydomain.com. The Client machine is a Windows 2008 Server R2 Enterprise Edition server The Remote Desktop Services role is configured on this server Remote Connection settings are configured to allow users to connect with any version of the Remote Desktop Client All accounts are members of the local Administrators and Remote Desktop Users groups All accounts are configured to be forced to change the default password after first login The user is instructed to remote into the lab with an account designated as their main account, and establish 3 more remote desktop sessions within the lab using their 3 other assigned demo lab accounts. When establishing the initial remote desktop connection to the lab using their main account, the user sees the change password dialog as expected. However, after logging in and trying to establish remote desktop connections to the server with their three other accounts, they are prompted that they need to change the password after logging in but can't continue with the login process - they don't see the expected change password experience. After logging in with a primary accounts, it doesn't make a difference if I try establishing a Remote Desktop connection to the environment using the name of the server, e.g. Client, or demolab.mydomain.com. I experimented with changing the settings for Remote Connections to require NLA but that didn't make a different. Appreciate any tips. Thanks

• Setting up self signed cert and CA [plesk / linux]

  - by microchasm

  I'm about ready to give up and do a clean wipe of this machine and start over with ISPConfig or some other variant. I installed Plesk on this machine to help with some of the handiwork. It is the free version (single domain); I don't need it for much. It's nice, though, to use to set up db's email, etc. Anyway, I would like to set it up as a CA (which I can add to users' trusted root servers to alleviate those warnings). It seems like Plesk does all it can to obfuscate where things are. Despite trying to find the conf files, and crt/pem/key etc. I am (5 hours later) now left with a machine that won't even get to the ssl page. The browser will sit there, until a 'connection reset' error comes up. In error_log, I get messages saying CN doesn't match server name -- which it does. ssl_error_log: [Thu May 13 16:02:14 2010] [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?) [Thu May 13 16:12:19 2010] [warn] RSA server certificate is a CA certificate (BasicConstraints: CA == TRUE !?) not very helpful. If anyone has any experience, and/or recommendations (including other software), I'd be much obliged. NB RHEL5; 1 domain, 3 subdomains; everything local only. Thanks.
