• External USB HD with -optional- mains?

  - by Stephen

  Hi, I'm Christmas-present-buying, and I'd appreciate recommendations for a USB HD with an optional mains power input. I've hunted, but can't find all the information I want (partially due to sketchy product specifications). Background: This is for a digital TV which I do not own, and so I'd like to get it correct first time. The TV has a USB port to allow recording straight to disk, but the manuals don't say how much power can be drawn through the USB port. The manual's instructions state, possibly generically, to plug the drive in before connecting to the TV. Ideally I'd like a small (2.5"?) drive which can draw power over USB, with an mains power input if it turns out the USB port on the TV doesn't offer enough juice. The ideal is to use one cable, two max. A powered USB hub would introduce too much clutter. I've spotted that the LaCie Petit drives have what appears to be an additional power input, but I'm not even sure from the specs what that is. And the device doesn't ship with a mains adapter. Suggestions?

• PHP Output buffer flush issue on Apache/Linux

  - by Iiro Vaahtojärvi

  Hi, I'm running into issues with the PHP output buffer flushing on my Linux web server. The output buffer is maintained correctly and all the right data is pushed to it in my code, but the usual flushing mechanisms won't flush it to the browser. I have tried everything posted here: http://php.net/manual/en/function.flush.php but no success so far. I got a small script from php.net to test it: <?php ob_start(); for($i=0;$i<70;$i++) { echo 'printing...<br />'; ob_get_flush(); flush(); usleep(300000); } ?> This should print "printing..." to the browser 70 times, one line every three seconds. This works fine on my other testing environment which is based on Windows (still using apache, XAMPP package), but on my Linux server it doesn't. It waits for the script to finish before giving anything to the browser, basically ignoring the whole flush command. If anyone has experienced this before or knows of anything that could help (be it server configuration or adjustment to code) it would be greatly appreciated!

• Automate creation of Windows startup script?

  - by Niten

  Is there a good way to automate installing local startup (rather than login) scripts in Windows XP and Windows 7, via the command line, WMI, or otherwise (even COM or Win32 if it comes to that)? I need to setup a local startup script on a large number of computers, and unfortunately, Active Directory is absolutely not an option. I would like to write a script or small program that I can run on each computer to perform the startup script installation in order to save myself a lot of error-prone point-and-click manual labor. I see that when one uses gpedit.msc to create a local startup script, information about the script gets stored in the registry here: HKLM\Software\Policies\Microsoft\Windows\System\Scripts\Startup However, if you create such a script and then delete its registry key, the script will remain listed in the local Group Policy editor; as is so often the case in Windows, apparently there is more going on there than meets the eye. This leads me to question whether it's safe to manually add subkeys for new startup scripts here (I wouldn't want my script to be overwritten by later changes made using the local Group Policy editor, for instance)... Another option that's occurred to me is to create an item in the Task Scheduler configured to run at system startup. However, my concerns there are twofold: Can this be automated any more easily? For instance, the at command doesn't appear to let you schedule a task for system startup, and WMI's Win32_ScheduledJob interface looks unreliable (it fails to show any of my currently scheduled tasks, for one thing). Would I be able to prevent users from logging in until the scheduled startup task is completed, as can be done with "normal" Windows startup scripts? Thanks in advance for any suggestions, I've been banging my head against this one for a bit...

• HTTPS and Certification for dummies

  - by Poxy

  I had never used https on a site and now want to try it. I did some research, but not sure that I understood everything. Answers and corrections are greatly appreciated. Here we go: To use https I need to generate ‘private’ and ‘public’ keys for the web server I use. In my case it’s apache (manual: http://httpd.apache.org/docs/2.0/ssl/ssl_faq.html) Https protocol should be bind to port 443. Q: How to do it? Is it done by default? Where can I check configuration? Aplying https. Q: If I see https in browser does it mean that the data traffic on the page IS encrypted? Any form on the page would submit data via https? Though all the data gonna be encrypted, the browsers would still show ugly red messages. This is just because they do not know anything about my certificate. They have about a hundred certificates pre-installed but mine is not one of them, obviously. But the data IS encrypted by https. If I want browsers to recognize my certificate, I would need to have it signed by one of the certification authorities (ca) that has its certificate pre-installed (e.g. thawte, geotrust, rapidssl etc). UPD: To reed about ssl/tsl: The First Few Milliseconds of an HTTPS Connection, I found it very informative. Examples for PHP (openssl.org) of how to make use of ssl/tsl on the server side are published here.

• Remote search system for samba shares

  - by fostandy

  I have several shares residing on a samba server in a small business environment that I would like to provide search facilities for. Ideally this would be something like google desktop with some extra features (see below), but lacking this the idea is to take what I can get, or at least get an idea for what is out there. Using google desktop search as a reference model, the principle additional requirement is that it is usable from clients over the network. In addition there are some other notes (note that none of these are hard requirements) The content is always files, residing on a single server, accessible from samba shares. Standard ms office document fare Also a lot of rars and zips which it is necessary to search inside. Permissions support, allowing for user-based control to reflect current permission access in samba shares. The userbase will remain fairly static, so manual management of users is fine. majority of users will be Windows based I know there are plenty of search indexers out there: beagle and tracker seem to be the most popular. Most do not seem to offer access control and web-based/remote search does not seem to be high priority. I've also seen a recent post on the samba mailing list asking for pretty much the exact same thing. (They mention a product called IBM OmniFind Yahoo! Edition and while their initial reception seems positive, I am pretty skeptical. RHEL 4? Firefox 2? Updated much?) edit: similar question here What else is out there? Are you in a similar situation? What do you use?

• Resize a RAID 1 volume on OS X Snow Leopard - how? (Note: software raid)

  - by Emmel

  I've scoured the Internet in search of an answer to this question, and as usual with OSX-related topics, I often don't find any deep-dive technical explanations sufficient enough to feel confident doing dangerous things. Here is my question: I have a Mac Pro, running OS X 10.6.2. I have, as my main root/boot disk, a RAID 1 volume called "Mirror1". Mirror1 is comprised of two 1 TB disks. Mirror1, however, is fixed at 640 GB. That's because, I originally took a 640GB disk, bought a terabyte disk, mirrored it (using diskutil appleraid enable), when it synced I removed the 640GB and replaced it with a second 1 TB disk, and synced again. Voila! A single 640 GB replaced by two 1 TB disks in a mirror.. Actually, no. There's still something missing from the equation: Mirror1 needs to be expanded from 640GB to 1 TB to match the partition sizes on each of those disks. How do I do this? Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

• How to auto mark tape as free in DPM 2012?

  - by Massimo

  I have a backup server running System Center Data Protection Manager 2012, connected to a couple of tape drives (no library). I also have, of course, some tapes. Tape rotation is manual. The tape have been used before, by DPM itself (but the server has been completely rebuilt) and by other backup softwares; they are not emtpy. But they contain no data that DPM knows and/or wants to preserve, so they can be marked as free without having to run forcefreetape.ps1. When a tape is placed into the drive, it is required to perform an inventory, have it recognized as an imported tape and then mark it as free; otherwise DPM will simply refuse to use it. How can I tell DPM to automatically treat those imported tapes as free? And, of course, I do not want to reuse real backup tapes if by chance they get put into the drives before their expiration date, so the solution should mark imported tapes as free, but should not do the same with real, non-expired tapes.

• Have an unprivileged non-account user ssh into another box?

  - by Daniel Quinn

  I know how to get a user to ssh into another box with a key: ssh -l targetuser -i path/to/key targethost But what about non-account users like apache? As this user doesn't have a home directory to which it can write a .ssh directory, the whole thing keeps failing with: $ sudo -u apache ssh -o StrictHostKeyChecking=no -l targetuser -i path/to/key targethost Could not create directory '/var/www/.ssh'. Warning: Permanently added '<hostname>' (RSA) to the list of known hosts. Permission denied (publickey). I've tried variations using -o UserKnownHostsFile=/dev/null and setting $HOME to /dev/null and none of these have done the trick. I understand that sudo could probably fix this for me, but I'm trying to avoid having to require a manual server config since this code will be deployed on a number of different environments. Any ideas? Here's a few examples of what I've tried that don't work: $ sudo -u apache export HOME=path/to/apache/writable/dir/ ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=path/to/apache/writable/dir/.ssh/known_hosts -l deploy -i path/to/key targethost $ sudo -u apache ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=path/to/apache/writable/dir/.ssh/known_hosts -l deploy -i path/to/key targethost $ sudo -u apache ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -l deploy -i path/to/key targethost Eventually, I'll be using this solution to run rsync as the apache user.

• pppd disconnects from 3G, doesn't reconnect, w/ persist set

  - by bytenik

  I am trying to configure pppd to connect to a 3G network (Sprint, in this case) and then stay connected, reconnecting automatically if the remote connection is terminated. I have enabled the persist option. My configuration file is as follows: hide-password noauth connect "/usr/sbin/chat -v -f /etc/chatscripts/cellular" debug /dev/cell 921600 defaultroute noipdefault user " " persist maxfail 0 lcp-echo-failure 10 lcp-echo-interval 60 holdoff 5 However, when the peer disconnects the connection, pppd often waits a long time (substantially more than my holdoff) to reconnect the modem -- if it ever reconnects at all! An example log showing this: May 23 05:17:24 00270e0a8888 pppd[2408]: rcvd [LCP TermReq id=0x26] May 23 05:17:24 00270e0a8888 pppd[2408]: LCP terminated by peer May 23 05:17:24 00270e0a8888 pppd[2408]: Connect time 60.1 minutes.

I had a friend monitoring the server so I'm not certain that this wasn't a manual reconnection. Either way, it either took almost an hour to reconnect or never reconnected. Shouldn't persist + holdoff 5 cause this to automatically reconnect after 5 seconds of the link terminating?

• PC can't detect second RAM installed

  - by kulwinder

  I have PC with 512 MB RAM installed (motherboard manufacture MICRO STAR, chipset P4M800), pc was running very slow so I decided to upgrade the ram. I installed CPU-Z and check the ram installed on the machine, also had a look at the stick installed. 512 MB PC 3200 400 MHz DDR but my mother supports 200 MHz and it was working ok. So I bought 2GB which I checked on manual that it support upto 2 GB Ram. So I installed 2GB PC 3200 400 MHz same as the old one, I plugged in both eventhough motherboard only support upto 2 GB but system spec only shows 512 (deducts 64 MB shared vga memory) I checked on CPU-Z, it detects both, slot 1 512 MB, slot 2 2048 MB, comparing screen for both slots, both the same, volt 2.5, frequency 166 MHz and 200MHz, only difference on those is 2gb ram shows under timings table 133MHz 166 MHz and 200MHz but 512 MB shows only 166MHz and 200MHz. I checked on Google and can't seems to figure out whats wrong with it. If I only plug in 2GB. Pc doesn't boot up like ram not working.With only 512 MB plugged in seems ok. Please help.

• Network Load Balancing and AnyCast Routing

  - by user126917

  Hi All can anyone advise on problems with the following? I am planning on installing the following setup on my estate: I have 2 sites that both have a large amount of users. Goals are to keep things simple for the users and to have automatic failover above the database level. Our Database will exist at the primary site and be async mirrored to the secondary site with manual failover procedures.The database generate sequential ID's so distributing it is not an option. I plan to site IIS boxes at both sites with all of the business logic on them and heavy operations. The connections to SQL will be lightweight and DB reads will be cached on IIS. On this layer I plan to use Windows network load balancing and have the same IP or IPs across all IIS boxes at both sites. This way there will be automatic failover and no single point of failure. Also users can have one web address regardless of which site they are in automatically be network load balanced to their local IIS. This is great but obviously our two sites are on different subnets and as this will be one IP address with most of our traffic we can't go broadcasting everything across the link between the sites. To solve this problem we plan to use AnyCast routing over our network layer to route the traffic to the most local box that is listening which will be defined by the network load balancing. Has anyone used this setup before? Can anyone think of any issues with this? Also some specifics I can't find anywhere at the moment. If my Windows box is assigned an IP and listening on that IP but network load balancing is not accepting specific traffic then will AnyCast route away from that? Also can I AnyCast on a socket level?

• Setting MSN or Yahoo! Messenger status to Invisible or Offline when idle for an hour

  - by Jian Lin

  Where, or how, do I set it up in MSN Messenger or Yahoo! Messenger to automatically switch my status to either "Invisible" or "Offline" when idle for a half hour, or an hour? I know how to set my status as "Away" or "Busy" after 10 minutes, but can't seem to find a way to set the offline status options without manual intervention. Back story As a software developer, I am very used to turning the computer on for the whole day and not turning it back off. (For example, checking email for urgent fixes, fix issue and push to web server). It's not even turned off when heading to sleep in case I might find it hard to fall asleep and come back to check on the computer. Or to have it there ready in the morning to check that everything is okay. If I'm seen as being online for 24 hours of a day, some people see me as weird. Their perception of my value decreases as I'm always there (hard to get = high value; always there = low value). Leaving it on makes everyone in my contacts list think I have nothing better to do all day than sit in front of the computer. Even though it's my job and I do admittedly spend more time online than other people. That's why I'd like to find a way to set my status as Invisible or Offline.

• Why Is Volume Shadow Copy Services stopping?

  - by David Mackintosh

  I am running Windows 7 Professional, 64-bit. I am running a backup-over-the-internet software client which depends on the Volume Shadow Copy Services running. Since I installed Service Pack 1 (or rather, didn't object when Windows Update forced Service Pack 1 on me) the backup service is failing to back everything up because VSC isn't running. Most of the time it fails to back up such noise as the Security Essentials database or the Messenger Live contact list -- stuff I really don't care about -- but I don't want to fall into the trap of accepting an Error-state backup as "normal". At the recommendation of the backup software, I have set the VSC service startup mode to be Automatic. When I look in the Event Log, System channel I can see at boot time: The Volume Shadow Copy service entered the running state. ...and then two or three minutes later: The Volume Shadow Copy service entered the stopped state. How do I figure out why VSC is stopping? At the suggestion of the backup vendor, I have already followed the suggestions from http://support.microsoft.com/default.aspx/kb/940184 net stop SENS net stop EventSystem net start EventSystem net start SENS net stop COMSysApp net stop SwPrv net stop VSS cd /d C:\Windows\system32 regsvr32 ole32.dll /s regsvr32 oleaut32.dll /s regsvr32 vss_ps.dll /s vssvc /register /s regsvr32 /i swprv.dll /s regsvr32 /i eventcls.dll /s regsvr32 es.dll /s regsvr32 stdprov.dll /s regsvr32 vssui.dll /s regsvr32 msxml.dll /s regsvr32 msxml3.dll /s regsvr32 msxml4.dll /s net start SwPrv net start VSS net start ProtectedStorage ...and per http://support.microsoft.com/kb/940184 I have deleted the key tree HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\EventSystem\{26c409cc-ae86-11d1-b616-00805fc79216}\Subscriptions I have also run chkdsk /F and chkdsk /R on both permanent hard disks. (I had a similar problem with another computer (same OS, same failure, same start point after SP1 install) but the problem went away when I forced Volume Shadow Copy Services to Automatic startup rather than Manual. I did not have to resort to following the Microsoft KB instructions.)

• SQL Error (1064) when importing data from SQL file

  - by mejpark

  I have a MySQL database, which was originally set up with the default latin1 character set and latin1_swedish_ci collation. I was using the database like this for sometime, until I noticed strange characters on my production web site, which is powered by a database exported from my development machine. At this point, I changed the default character set of the database and tables to utf8 and the collation to utf8_unicode_ci, converted the latin1 data inside each table to utf8 (using the 'convert data' option) and exported the database as a single SQL file using HeidiSQL. When the resulting SQL file is opened in Notepad++, several characters are rendered incorrectly. For example, en dashes (-) are displayed as – and e with accent (é) are displayed as é. I changed the encoding of the file from ANSI to UTF-8 (using the encoding menu option in Notepad++) and the offending characters are rendered correctly. I saved the new utf8-encoded SQL file and attempted to import the contents into the MySQL database on my production server. The import process fails with following error: /* SQL Error (1064): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '?# -------------------------------------------------------- # Host: ' at line 1 */ /* Error with snippets directory: The specified path was not found */ The head of the SQL file: # -------------------------------------------------------- # Host: 127.0.0.1 # Server version: 5.1.33-community # Server OS: Win32 # HeidiSQL version: 6.0.0.3773 # Date/time: 2011-04-20 09:48:36 # -------------------------------------------------------- It chokes on the first line of the file, which is commented out. Why is this happening? I didn't have a problem loading data from SQL files until I changed the character set and collation of the database. I came up with an ugly workaround to this problem by performing following steps: Export database as single SQL file using HeidiSQL Open resulting file in Notepad++ and convert from ANSI to UTF-8 encoding Create new empty file in Notepad++, paste in UTF-8 and save file normally What am I missing here?

Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

• The SSL certificate doesn't established

  - by Andrey Eagle

  situation following: Windows Server 2008 R2 platform. Certificate installation in the IIS Manager occurs successfully with *.cer file but if I refresh the manager (F5), the certificate vanishes from the list. And, respectively in the Bindings window, at https addition, the certificate is absent in the menu. Thus if to open certificates via the MMS console, it can be seen in the Personal store. Whether there is any possibility to make so that the web server could "see" this certificate or how to make so that it didn't disappear from the list? Prompt how to solve this problem, thanks in advance! P.S. The certificate is acquired in tawte. In total that to me provided, these are account data where it is possible simply with save-pastit the certificate in 2 options: PKCS#7 and X.509. Here is the manual I used. P.S.2 If Complete Certificate Request with *.p7b I get an error: Cannot find the certificate request that is associated with this certificate file. Acertificate request must be comleted on the computer where the request was created.

• IP-dependent local port-forwarding on Linux

  - by chronos

  I have configured my server's sshd to listen on a non-standard port 42. However, at work I am behind a firewall/proxy, which only allow outgoing connections to ports 21, 22, 80 and 443. Consequently, I cannot ssh to my server from work, which is bad. I do not want to return sshd to port 22. The idea is this: on my server, locally forward port 22 to port 42 if source IP is matching the external IP of my work's network. For clarity, let us assume that my server's IP is 169.1.1.1 (on eth1), and my work external IP is 169.250.250.250. For all IPs different from 169.250.250.250, my server should respond with an expected 'connection refused', as it does for a non-listening port. I'm very new to iptables. I have briefly looked through the long iptables manual and these related / relevant questions: http://serverfault.com/questions/57872/iptables-question-forwarding-port-x-to-an-ssh-port-of-different-machine-on-the-n http://serverfault.com/questions/140622/how-can-i-port-forward-with-iptables However, those questions deal with more complicated several-host scenarios, and it is not clear to me which tables and chains I should use for local port-forwarding, and if I should have 2 rules (for "question" and "answer" packets), or only 1 rule for "question" packets. So far I have only enabled forwarding via sysctl. I will start testing solutions tomorrow, and will appreciate pointers or maybe case-specific examples for implementing my simple scenario. Is the draft solution below correct? iptables -A INPUT [-m state] [-i eth1] --source 169.250.250.250 -p tcp --destination 169.1.1.1:42 --dport 22 --state NEW,ESTABLISHED,RELATED -j ACCEPT Should I use the mangle table instead of filter? And/or FORWARD chain instead of INPUT?

• Autologin 2 Windows users OR Login another user from the desktop

  - by fpdragon

  I'm using two windows users on my HTPC at the same time. One is just for watching videos and one for administration via remote. This setup is quite ideal for me since windows can handle multiple concurrent logins and the win "rdp concurrent hack" (Google). The problem is, I want both users to be logged in automatically when the pc was started. It shall be possible to watch tv and also the admin user shall be automatically logged in to start my scripts and other tasks, even if I haven't logged in via remote desktop manually. Later, when I want to admin my htpc I can just rdp connect the admin user without interrupting the video playback on the actual HTPC's screen and check my cleanup tasks, downloads, ... witch already executed for this admin user. But right now I found no solution to automatically login user A from a user B desktop and I also found no solution to autologin both users immediately at startup. As a workaround I have to fire up my other notebook machine and login one time with the remote user via rdp. From this time on the remote admin user is running concurrent with the main user in the background of the machine. The other workaround would be... after startup switch user from main user to admin user and then back again. But that also requires manual steps. I'm on a Windows 8 System right now but all infos for Win7 or XP would be also interesting. thanks a lot for all ideas. PS: just to prevent useless posts... don't tell me that only one user can be logged in to windows. ;)

• SQL Server Database In Single User Mode after Failover

  - by jlichauc

  Here is a weird situation we experienced with a SQL Server 2008 Database Mirroring Failover. We have a pair of mirrored databases running in high-availability mode and both the principal and mirror showed as synchronized. As part of some maintenance I triggered a manual failover of the principal to the mirror. However after the failover the principal was now in single-user mode instead of the expected "Principal/Synchronized" state we usually get. The database had been in multi-user mode on the previous principal before this had happened. We ended up stopping all applications, restarting the SQL Server instances, and executing "ALTER DATABASE ... SET MULTI_USER" to bring the database back to the expected "Principal/Synchronized" state in a multi-user mode. Question. Does anyone know where SQL Server stores information about whether a database should be in single-user mode or not? I'm wondering if there is some system database or table that has this setting recorded somewhere. In particular we had an incident once with the database on the original principal (the one I was failing over to) where when trying to detach the database it was put into single-user mode. I'm wondering if that setting is cached somewhere and is the reason that SQL Server put it back into single-user mode after a failover.

• Create a wifi hotspot in a place where an authentication is required

  - by SoftTimur

  I live in a residence where Internet is provided via cable. Once the computer is connected to the cable, launching a browser will trigger an authentication, I have a username and password to enter, then the internet will be connected. With a gateway (e.g. Wireless Cable Voice Gateway Model CBVG834G) and 2 cables, two PCs can connect to the Internet with my account at the same time. Now the question is, I don't like the cable, and would like to create a wifi hotspot. It seems realizable with the same gateway. According to the instruction on page 2-4 of the manual: Enter http://192.168.0.1 in the address field of your Internet browser. Log in to the gateway with either of the default user names, MSO or admin... However, while connecting to the Internet successfully via cable and the gateway (e.g. google works), opening 192.168.0.1 oddly gives me an error on the browser: Does anyone know what happened? Is it due to the authentication required by my residence? Is there any other way to build a hotspot of wifi? PS: My system is MAC OS

• Linux drivers for laser printer Konica Minolta Magicolor 4750DN

  - by user51166

  I would like to install the konica minolta magicolor 4750DN in Linux (debian 64 bits, I know it's not really supported but that's not the issue right now) but all the manual says is "put the CD rom in and copy the drivers and PPD file". However I did not get the CD ! On their "fantastic" internet site (...) there are only available drivers for Windows and Mac OSX. I tried to extract the ppd file from the .dmg file for MacOSX 10.7 but, if the PPD file works, a compiled file (only mac compiled, MACH 4 architectures says the "file" command) does not (obviously "cannot execute binary file", since I'm trying to run a Mac file on Linux). Is there anybody who has the same printer that could lend me the Linux drivers on the CD ROM ? Couldn't find them anywhere on the internet. Any way to execute a Mach (or BSD) binary file on Linux (I don't think is possible, although some "emulators" may exist). Thank you very much. I buyed this printer even because it was advertised as "Linux compatible", only to get this bad surprise. I would be grateful if you could help me solve this problem.

• Mac OS Leopard: SyncServer process constantly using 100% CPU

  - by macca1

  I am running Leopard that I upgraded from Tiger. I've been noticing that every once in a while the SyncServer process starts up and eats up all the CPU. The fans will start going at full blast and the laptop will slow down to a crawl. I need to force quit the process from Activity Monitor to get it under control. It disappears for a while, but eventually gets started again. I do have an iphone as well that I sync so I'm wondering if syncServer might be an apple process checking for my phone plugged in. Edit: Tried iSync and the manual resetsync as suggested, but got this output: Vince-2:~ vince$ /System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync.pl full 2010-03-12 08:03:50.230 perl[176:10b] SyncServer is unavailable: exception when connecting: connection timeout: did not receive reply PerlObjCBridge: NSException raised while sending reallyResetSyncData to NSObject object name: "ISyncServerUnavailableException" reason: "Can't connect to the sync server: NSPortTimeoutException: connection timeout: did not receive reply ((null))" userInfo: "" location: "/System/Library/Frameworks/SyncServices.framework/Versions/A/Resources/resetsync.pl line 16" ** PerlObjCBridge: dying due to NSException Vince-2:~ vince$ And during that syncServer started spinning up 95-100% just like it always does.

• AviSynth ChangeFPS: combining videos with different framerates

  - by Daniel Saner

  I have two video recordings of the same scene, but with different framerates, that I would like to combine using an AviSynth script. One video is recorded at 30fps, the other at 120fps. What I would like to do is to keep them temporally synchronised, meaning that for each frame of the 30fps video, the output should display 4 frames from the 120fps video. I would like the final output video to play at 30fps so that the duration is 4 times the original recordings. From AviSynth's documentation, it seems ChangeFPS is the function I'll need, since it removes and duplicates frames, while 'AssumeFPS' just changes the playback speed (and my plan is basically to quadruple every frame of the 30fps clip). However, the filter does not seem to do what it says. If I try: clip30 = AviSource("0326.avi").ChangeFPS(120) clip120 = AviSource("0326-120fps.avi") it doesn't affect the playback speed or frame count of the 30fps clip at all, but removes every fourth frame from the 120fps clip, which is not at all what I want. Unfortunately, appending .ChangeFPS(7.5) to the clip120 instead does not have the same inverse effect—in that case, it does exactly what's to be expected. Alternatively, if I try: clip30 = AviSource("0326.avi").AssumeFPS(7.5) clip120 = AviSource("0326-120fps.avi") there is no effect at all, both clips are played back at 30fps, meaning that only a quarter of the 120fps clip has been shown by the time the 30fps clip is over. So how can I combine these two clips in the manner I want? I was unable to find any other internal or external filters that would help me do that. It seems to me that if ChangeFPS did what the manual says, it would be the right one for the job.
