How can I start hostednetwork on Windows 7?

When I type in admin console command to start hostednetwork netsh wlan start hostednetwork it gives me this: The hosted network couldn't be started. The group or resource is not in the correct state to perform the requested operation. There is a hotfix from Microsoft but it didn't help me. Any advice?

Want to send my neighbors to a certain website via DNS, but don't have a clue how. [closed]

- by Akku

My neighbors have an unsecured WIFI router, and over the administration web-UI of the router I could log in as there was no password set. I don't know which of my neighbors these are, and I'd like to configure their router in a way that they come to my website instead of Google and Facebook, where I set up a warning in german. It this page: http://www.abelssoft.de/liebenachbarn/ Basically, I just want to see if and how this is possible - I'm aware that I could just set the WiFi-password and have them call their network provider to reset the thing, but I really want to see if this could work, because it would be a way cooler effect :-). So this router interface doesn't allow custom redirects, only filters. BUT I can set the DNS that is used, so I thought there might be the possibility to set up a custom DNS on a server, set it as the main DNS and redirect from Google to the URL above. Is this possible? If so, please try to detail a way that I have to go though to achive this. Note that I'm not the super-Linux-skilled person, I have a dyndns account and a Windows machine it points to as well as an Apache+Tomcat if that helps. I could also set up virtual machines on the windows server and redirect to those using a different port. Or is there maybe a webservice that provides such custom DNS?

Running batch file through a service.

- by wallz

I'm trying to schedule a batch file to run through a third party application, however the output file doesn't get created in the directory. If I run the .BAT file from the command line, it works and the file gets created. Also using the Windows Schedule will also succeed. Basically, the 3rd party software will schedule the .BAT file and it shows success within the 3rd party user interface. The difference between running from the command prompt and the software, is that the software will use its Windows service to launch the batch. The 3rd party software will show success since it was able to successfully call the .BAT file to run, however it has no control of the other EXE's that's being called within the script. I'm able to run a simple .BAT file in the 3rd party software, for example a copy command. The .BAT I'm having problems with calls a compiled EXE which launches Excel to create a file to a location. The .bat file calls something.exe, which then calls Excel.exe: C:\something.exe -o D:\filename.xlsm C:\filename.xlsm refresh_pivot Do you think it's a permissions issue? I used Process Monitor to verify any Access Denied errors but everything seems to be working according to the trace. It worked on a non-64-bit OS, I'm currently using Win2008 64-bit.

What to do with old laptop screens?

- by Lord Torgamus

This question is inspired by another SU question I came across earlier today: What to do with old hard drives? It made me think about two long-dead laptops I have with perfectly good screens still inside. One is a Dell Inspiron 5100 and the other is an Averatec E1200, but responses need not be geared towards those particular models' screens. Rules, based heavily on the original question's: Objectives and suggestions to keep in mind when you post an answer : Should showcase your geekiness, be plain ol' fun, serve a social purpose or benefit the community. Your answer need not be limited to only one screen. For a really good answer, I'll go out and buy additional leftover screens. Your answer need not be limited to one project per screen. If additional accessories need be purchased, make sure they are common. Don't tell me to get a moon rock or something. The projects you suggested should serve a useful purpose; art is nice, but functional art is way better. Thanks in advance, folks. EDIT: Found another related question. Fun projects to do with an old 17" LCD monitor EDIT 2: I, for one, am enjoying the new outpouring of creativity here. Best fifty bucks... I mean, rep points... I ever spent. EDIT 3: That does it. At the end of the week, there was a tie for most votes between the accepted answer and the game platform answer. The game platform answer was cooler, but less reasonable as a project to actually do; in other words, it was more moon rocky. Unfortunately, I think fencepost had the best comment on the topic, which is that displays on their own have no good interface. Thanks for playing, everyone!

How to fix GMail time stamps in Outlook?

- by SWB

One of my email accounts is hosted at an ISP with unreliable IMAP support, and I can't change it. Fortunately, I have my personal email set up on Google Apps for Domains, so I created another GMail account there and turned on GMail's features that allow me to send and receive mail through the ISP account using GMail ("Send mail as" and "Get mail from other accounts" in GMail settings on the Accounts tab). I'm now using Outlook to retreive mail from the GMail account through IMAP, which in turn is retreiving mail from the ISP account through POP3. This basically works great, except for one very significant issue: Prior to setting this up, I already had several months of mail in the ISP account that I had been accessing via IMAP. GMail grabbed all of this mail via POP3 at, let's say, noon on April 5. In GMail's web interface (and on my iPod touch, and in Mozilla Thunderbird), all is well: the messages are all shown with their original time stamps. But when Outlook downloads these messages from GMail via IMAP, the time stamps are all set to noon on April 5 (the time GMail downloaded them from the ISP via POP3). That's not good, especially since we're talking about hundreds of messages here over a time span of several months. How can I fix this and get Outlook to display the original time stamps?

How to reduce celeryd memory consumption?

- by Gringo Suave

I'm using celery 2.5.1 with django on a micro ec2 instance with 613mb memory and as such have to keep memory consumption down. Currently I'm using it only for the scheduler "celery beat" as a web interface to cron, though I hope to use it for more in the future. I've noticed it is the biggest consumer of memory on my micro machine even though I have configured the number of workers to one. I don't have many other options set in settings.py: import djcelery djcelery.setup_loader() BROKER_BACKEND = 'djkombu.transport.DatabaseTransport' CELERYBEAT_SCHEDULER = 'djcelery.schedulers.DatabaseScheduler' CELERY_RESULT_BACKEND = 'database' BROKER_POOL_LIMIT = 2 CELERYD_CONCURRENCY = 1 CELERY_DISABLE_RATE_LIMITS = True CELERYD_MAX_TASKS_PER_CHILD = 20 CELERYD_SOFT_TASK_TIME_LIMIT = 5 * 60 CELERYD_TASK_TIME_LIMIT = 6 * 60 Here's the details via top: PID USER NI CPU% VIRT SHR RES MEM% Command 1065 wuser 10 0.0 283M 4548 85m 14.3 python manage_prod.py celeryd --beat 1025 wuser 10 1.0 577M 6368 67m 11.2 python manage_prod.py celeryd --beat 1071 wuser 10 0.0 578M 2384 62m 10.6 python manage_prod.py celeryd --beat That's about 214mb of memory (and not much shared) to run a cron job occasionally. Have I done anything wrong, or can this be reduced about ten-fold somehow? ;) Update: here's my upstart config: description "Celery Daemon" start on (net-device-up and local-filesystems) stop on runlevel [016] nice 10 respawn respawn limit 5 10 chdir /home/wuser/wuser/ env CELERYD_OPTS=--concurrency=1 exec sudo -u wuser -H /usr/bin/python manage_prod.py celeryd --beat --concurrency=1 --loglevel info --logfile /var/tmp/celeryd.log Update 2: I notice there is one root process, one user child process, and two grandchildren from that. So I think it isn't a matter of duplicate startup. root 34580 1556 sudo -u wuser -H /usr/bin/python manage_prod.py celeryd wuser 577M 67548 +- python manage_prod.py celeryd --beat --concurrency=1 wuser 578M 63784 +- python manage_prod.py celeryd --beat --concurrency=1 wuser 271M 76260 +- python manage_prod.py celeryd --beat --concurrency=1

Linux iptables / conntrack performance issue

- by tim

I have a test-setup in the lab with 4 machines: 2 old P4 machines (t1, t2) 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t3) Intel e1000 1 Xeon 5420 DP 2.5 GHz 8 GB RAM (t4) Intel e1000 to test linux firewall performance since we got bitten by a number of syn-flood attacks in the last months. All machines run Ubuntu 12.04 64bit. t1, t2, t3 are interconnected through an 1GB/s switch, t4 is connected to t3 via an extra interface. So t3 simulates the firewall, t4 is the target, t1,t2 play the attackers generating a packetstorm thorugh (192.168.4.199 is t4): hping3 -I eth1 --rand-source --syn --flood 192.168.4.199 -p 80 t4 drops all incoming packets to avoid confusion with gateways, performance issues of t4 etc. I watch the packet stats in iptraf. I have configured the firewall (t3) as follows: stock 3.2.0-31-generic #50-Ubuntu SMP kernel rhash_entries=33554432 as kernel parameter sysctl as follows: net.ipv4.ip_forward = 1 net.ipv4.route.gc_elasticity = 2 net.ipv4.route.gc_timeout = 1 net.ipv4.route.gc_interval = 5 net.ipv4.route.gc_min_interval_ms = 500 net.ipv4.route.gc_thresh = 2000000 net.ipv4.route.max_size = 20000000 (I have tweaked a lot to keep t3 running when t1+t2 are sending as many packets as possible). The result of this efforts are somewhat odd: t1+t2 manage to send each about 200k packets/s. t4 in the best case sees aroung 200k in total so half of the packets are lost. t3 is nearly unusable on console though packets are flowing through it (high numbers of soft-irqs) the route cache garbage collector is no way near to being predictable and in the default setting overwhelmed by very few packets/s (<50k packets/s) activating stateful iptables rules makes the packet rate arriving on t4 drop to around 100k packets/s, efectively losing more than 75% of the packets And this - here is my main concern - with two old P4 machines sending as many packets as they can - which means nearly everyone on the net should be capable of this. So here goes my question: Did I overlook some importand point in the config or in my test setup? Are there any alternatives for building firewall system especially on smp systems?

Why do I have redundant routing in Windows 7?

- by Mark

I'm trying to better understand my routing tables. My routing table is: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 1. 0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.151 25 2. 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 3. 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 4. 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 5. 192.168.1.0 255.255.255.0 On-link 192.168.1.151 281 6. 192.168.1.151 255.255.255.255 On-link 192.168.1.151 281 7. 192.168.1.255 255.255.255.255 On-link 192.168.1.151 281 8. 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 9. 224.0.0.0 240.0.0.0 On-link 192.168.1.151 281 10. 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 11. 255.255.255.255 255.255.255.255 On-link 192.168.1.151 281 =========================================================================== Most of those entries make sense to me, but a few confuse me: 2 and 3 seem redundant, as do 2 and 4. Why not just 2? 5 and 6 seem redundant, as do 5 and 7. Why not just 5? I'm trying to grok routing tables and this bit is still confusing me.

Viewing Postscript (or PDF) on OS X: Aliasing issues

- by mankoff

I am generating postscript graphics and am trying to find a balance between non-aliasing and over-aliasing. If I use the raw ghostscript viewer gs on the Postscript, it looks good. The text appears anti-aliased, but the image remains nice and blocky. Unfortunately, gs has no real user interface and loses all of the nice things that Preview.app has. I could install gv, but the dependency bloat is huge! It requires all of gnome. And even that isn't a great viewer compared to Preview.app or Skim.app. Here is an image viewed with gs: From a user-interaction and Mac-ish perspective, Preview.app (or Skim.app is a much nicer program to use. They have the option to turn on or off aliasing, but neither option looks very good. Which aliasing on, the image is blurry. When it is off, the graphic matches what is seen from gs, but there are two issues. Minor issue: the font is ugly. Uglier than with gs. Major issue: Every PDF is un-aliased, making it hard to read regular PDFs full of text. So, in summary: Is there a way to manually generate the PDF from the PS that overcomes these issues? Is there a way to find a middle ground of alias/unalias with Preview.app? Is there another app that displays with quality like gs, but has a decent UI like Skim.app or Preview.app Is there a way to have Preview.app turn off aliasing for only one file (containing graphics) but leave it enabled in general so that text PDFs are still readable?

exim4 seem to stop listening

- by trakos

Hey, I have a strange problem with my exim4 configuration. I have a dedicated server running debian for quite a long time now, but I'm not really using it actively recently, so everything just worked due to lack of changes ;) However, recently, my exim4 smtp stopped answering on port 25. It does not respond through localhost, as well - even though it's set to listen on any interface available. Some things I've checked: ks:/home/trakos/Maildir/new# netstat -ap | grep exim tcp 0 0 *:smtp : LISTEN 12521/exim4 ks:/home/trakos/Maildir/new# exiwhat 12521 daemon: -q30s, listening for SMTP on port 25 (IPv4) ks:/home/trakos/Maildir/new# cat /var/log/exim4/rejectlog ks:/home/trakos/Maildir/new# cat /var/log/exim4/paniclog The queue is set for 30s only because I was running it in a non-daemon mode to see any output. Strangely enough, no suspicious output is given, netstat even shows it is listening on port 25, but still trying to telnet to it times out. The only things that may have changed recently are: I've got second IP for my server I remember that few days ago my spamassasin crashed, and I've started it up again So yeah, I'm really clueless about this one now :P I mean, I don't even know what could be failing here. Could someone give me some ideas what should I check next? PS: it has uptime of 442 days, so I haven't really tried rebooting it yet ^^

openvpn in a bridge?

- by sebelk

I have a somewhat tricky proble to solve. We have a wireless link between 2 building. One of them has an mikrotik and below there are some vlans. Some machines of one vlan need to use openvpn to connect to a remote private lan. I put a TP-Link WR1043ND (which those machines connect to) with openwrt with ebtables just in case I need it. I've configured openwrt in such a way that all ports belongs to the same vlan. My idea was to make things as transparent as I can. It has a bridge as follows: usr/sbin/brctl-full show br-lan bridge name bridge id STP enabled interfaces br-lan 8000.f8d111565716 no eth0.1 eth0.2 Also I've added an ebtables rule: ebtables -t broute -A BROUTING -p ipv4 -j DROP So "bridge" has only one IP address. I've installed openvpn and I'm trying to bring up the tunnel but I can't still get working. Sure, someone can says why don't you use the vpn on the mikrotik, there are some reasons, the first one is I have little experience with mikrotik and I'd want to have the vpn at hand :) The problem is that openvpn is not working, because it is complaining that I have only one Ip Address on the server side. So I set up and alias interface with another IP address but is not working either: : Rejected connection attempt from IP-Client-Side:37801 due to --remote setting Is there a way to make it work?

Installing Visual Studio Express on Windows 8.1

- by robrene

I've been trying to install the latest version of Microsoft Visual Studio Express from their website to toy around with the IDE and C# development in general. I have a relatively fresh and completely vanilla installation of Windows 8.1 Professional x64 for this purpose. I come from a Linux background, where installing software (especially software distributed by the maintainer of the OS) is usually done with package managers. First, I tried to look for Visual Studio in the Windows 8 Store. There was one entry, but it did not have an installation button. Instead, it redirected me to their website. From all the products listed under the "Download" section on their website, I decided Visual Studio 2013 Express for Windows Desktop was the best for me. I selected it and clicked on "Install now". An installer program downloaded, and I'm assuming that the installer downloaded the necessary files as it was running. When it was done, it asked for a reboot, to which I obliged. However, I can't seem to find the IDE installed anywhere? It doesn't show up anywhere in the Start menu interface. I can't find any executables that look like they might be the IDE in its installation folder. Running the installer again and selecting "Repair" does download some files, but after its requested reboot, nothing has changed. The only thing that I can find is an advertisement link to "Try other Visual Studio 2013 Products" in my start menu. I suppose my question is what I have to do to run Visual Studio 2013 Express on Windows 8.1? Am I not looking in the right places? Am I doing the installation process wrong? Thanks in advance

Trouble setting up incoming VPN in Microsoft SBS 2008 through a Cisco ASA 5505 appliance

- by Nils

I have replaced an aging firewall (custom setup using Linux) with a Cisco ASA 5505 appliance for our network. It's a very simple setup with around 10 workstations and a single Small Business Server 2008. Setting up incoming ports for SMTP, HTTPS, remote desktop etc. to the SBS went fine - they are working like they should. However, I have not succeeded in allowing incoming VPN connections. The clients trying to connect (running Windows 7) are stuck with the "Verifying username and password..." dialog before getting an error message 30 seconds later. We have a single external, static IP, so I cannot set up the VPN connection on another IP address. I have forwarded TCP port 1723 the same way as I did for SMTP and the others, by adding a static NAT route translating traffic from the SBS server on port 1723 to the outside interface. In addition, I set up an access rule allowing all GRE packets (src any, dst any). I have figured that I must somehow forward incoming GRE packets to the SBS server, but this is where I am stuck. I am using ADSM to configure the 5505 (not console). Any help is very much appreciated!

Full-text search locks up database - error 0x8001010e

- by Stewart May

Hi We have a full-text catalog that is populated via a job every 15 minutes like so: ALTER FULLTEXT INDEX ON [dbo].[WorkItemLongTexts] START INCREMENTAL POPULATION We have encountered a problem where the database containing this catalog locks up. There are a couple of scenarios, we either see the job execute and the process hang with with a wait type of UNKNOWN TOKEN, or we see another process hang with a wait type of MSSEARCH. Once this happens the job continues to run but informs us that the request to start a full-text index population is ignored because a population is currently active. Looking in the full text log files we see the following error each time these problems occur: 2010-04-21 08:15:00.76 spid21s The full-text catalog health monitor reported a failure for full-text catalog "XXXFullTextCatalog" (5) in database "YYY" (14). Reason code: 0. Error: 0x8001010e(The application called an interface that was marshalled for a different thread.). The system will restart any in-progress population from the previous checkpoint. If this message occurs frequently, consult SQL Server Books Online for troubleshooting assistance. This is an informational message only. No user action is required."'' The only solution is to restart the SQL Server service and then the full text service. This is now occuring on a daily basis now so any help would be appreciated.

Why is this iptables rule that does port forwarding not working?

I have a server bound to localhost:7060. It is using ipv6 socket instead of ipv4. Below is netstat outout. # netstat -an Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 10.200.32.98:1720 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:4122 0.0.0.0:* LISTEN tcp 0 0 0.0.0.0:4123 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:4123 127.0.0.1:43051 ESTABLISHED tcp 0 0 10.200.32.98:5555 10.200.32.44:53162 ESTABLISHED tcp6 0 0 :::5060 :::* LISTEN tcp6 0 0 ::ffff:127.0.0.1:7060 :::* LISTEN tcp6 0 0 :::23 :::* LISTEN tcp6 0 0 ::ffff:10.200.32.98:23 ::ffff:10.200.32.142:43505 ESTABLISHED tcp6 0 0 ::ffff:127.0.0.1:43051 ::ffff:127.0.0.1:4123 ESTABLISHED tcp6 0 0 ::ffff:10.200.32.98:23 ::ffff:10.200.32.44:53195 ESTABLISHED udp6 0 0 :::5060 :::* CLOSE # I want to setup a port forwarding rule that accepts connections on port 24 (on all interfaces loopback as well as eth0) and forward the data to localhost:7060. This is how I am setting up the iptables rule: iptables -t nat -A PREROUTING -p tcp --dport 24 -j DNAT --to 127.0.0.1:7060** It is not working. When I telnet from different box, I see the following $telnet 10.200.32.98 24 Trying 10.200.32.98... If I change the server to bind to *:7060 and set the following rule, it seems to work fine. iptables -t nat -A PREROUTING -p tcp --dport 24 -j REDIRECT --to-port 7060 But that will make my server available on WAN interface which I don't like. I feel it had something to do with ipv6 socket (tcp6 line in netstat output). This whole thing is done on an Android device with custom built Android platform image. How do I get this working?

Use both OpenVPN & eth0 together

I connect to a VPN using openVPN. Now, after the connection is established, all my traffic goes through tun0. My LAN gateway is 10.100.98.4...

I thought this is a drag-drop file copy feature like VMWare. I tried that. But I couldn't copy by drag-drop, ctrl-c ctrl-v either. Edit: I mean VBox 4.0 beta, not 3.x The release note is here. Download link is here.

I have a USB WiFi adapter, D-Link dwl-g122. I'm running Ubuntu 10.4. My laptop has a built-in wireless card that is connecting fine to the router. I plug in the usb and it never really connects. Here are some details: iwconfig wlan1 IEEE 802.11bg ESSID:"\x0B\xE1..." Mode:Managed Frequency:2.457 GHz Access Point: Not-Associated Tx-Power=19 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:on lshw -c network: *-network:1 description: Wireless interface physical id: 3 logical name: wlan1 serial: 00:13:46:8b:xx:xx capabilities: ethernet physical wireless configuration: broadcast=yes multicast=yes wireless=IEEE 802.11bg dmesg [ 1096.814176] wlan1: direct probe to AP xxx (try 1) [ 1096.820960] wlan1: direct probe responded [ 1096.820969] wlan1: authenticate with AP xxx (try 1) [ 1096.823790] wlan1: authenticated [ 1096.823869] wlan1: associate with AP xxx (try 1) [ 1096.827667] wlan1: RX AssocResp from xxx (capab=0x411 status=0 aid=1) [ 1096.827674] wlan1: associated [ 1142.590912] wlan1: deauthenticating from xxx by local choice (reason=3) lsmod|rt2 rt2500usb 19643 0 rt2x00usb 11260 1 rt2500usb rt2x00lib 32133 2 rt2500usb,rt2x00usb mac80211 238896 3 ath5k,rt2x00usb,rt2x00lib cfg80211 148725 4 ath5k,ath,rt2x00lib,mac80211 led_class 3764 3 ath5k,rt2x00lib,sdhci It looks like the driver loads but it doesn't feel like connecting. The behavior is identical even if I blacklist the other wifi card (using an ath5k driver). It's almost like it is using the wrong password or something. Does anyone know what is happening? Is anyone using Ubuntu successful?

Cisco 851 (IOS) router: FastEthernet 4 (WAN) got the shutdown flag.

- by cjavapro

At a customer location there was a Cisco 851 router (which uses IOS). The PCs on location were all of a sudden unable to connect. We came on site and found that FastEthernet 4 (the WAN port) was "administratively down". We ran these commands to resolve it config t interface fa4 no shutdown exit exit write Now the mystery is how the shutdown flag got there in the first place? The router was on battery backup... but during the outage it was power cycled by the customer. It is possible that there was a short outage by the ISP and that the power cycle caused the shutdown flag to come up. There may have been a hack or an attack pattern that caused the shutdown flag to come up. There may have been a hack or an attack pattern that the router to become unavailable and then caused the shutdown flag to be added on startup. Question: Does anybody have any clues? or at least remember that they had a shutdown flag come up on their WAN port also?

map linux drives to windwos 7 for media stream over internet

- by Ortix92

I'm trying to map a linux network drive to my windows 7 laptop, however this laptop is not on LAN. At home, I simply use Samba, but this obviously won't work over the internet. I'm trying to avoid VPN, so if there are other solutions, I would like to know about them. The reason I ask is because my university does this as well. We can simply map folders to our computers without VPN connections. I'm not sure what they are running as servers. The main reason is because I want to be able to access my files stored on my home server wherever I go. They are located in the /home/ folder (videos, music and pictures folder). I'm trying to keep my websites and media separate from each other. I wouldn't mind accessing them from a web interface either, but I would like to keep the directory structure intact. I remember having an app like that come with winamp and running it on my windows pc (As the server). Unfortunately it doesn't work for linux. Any ideas on what I could use? Would XBMC be able to help me out with this? I did do some researching but I couldn't find any concrete answers

What are the replacement options for an IDE hd for a DOS based system?

- by dummzeuch

I have got a few "embedded" systems running MSDOS 6.2 which boot from and store data to IDE hard disks. Since these drives are nearing their end of life, the question arises how we can replace them. The requirements are: DOS must be able to install and boot from these drives. They must be able to sustain heavy (mostly) write access. If possible, they should be able to survive moderate vibrations (not too bad since the current hds have survived several years of that) I considered the following options so far: other ide hard drives: Unfortunately modern IDE drives are too large so DOS cannot boot from them even if I create small partitions. Older IDE drives are just that: old, so they are probably not the most reliable ones any more. SSDs: There are a few SSDs with IDE interface available. I have not yet tried them. Does anybody have any experience with them? They look like the ideal replacement provided that DOS can boot from them and that writing speed does not deteriorate too much (the old hds are no race cars either). Compact Flash: There are adapters for using CF with IDE controllers and they work fine. DOS can boot from them and they have no problems at all with vibrations. What I am not sure about is their durability. DOS uses FAT so some very few sectors are written every time the medium is being written to. IDE to SATA converters: I have no idea whether they are any good. Has anybody tried them? It might be an option to use one of these to connect an SATA SSD to the system. Are there any alternatives that I have missed? (We are working on replacing these systems, but it will still take a few years.)

Active Directory problems while trying to perfom compare operation

- by Alex

I have CentOs 5.5 with Apache 2.2 and SVN installed. Also I have Windows 2003 R2 with Active Directory. I'm trying to authorize users via AD so each user have access to repo if he is a member of corespondent group in AD. Here is my apache config: LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so LDAPVerifyServerCert off ServerName svn.mydomain.com DocumentRoot /var/www/svn.mydomain.com/htdocs RewriteEngine On [Location /] AuthType basic AuthBasicProvider ldap AuthzLDAPAuthoritative on AuthLDAPURL ldaps://comp1.mydomain.com:636/DC=mydomain,DC=com?sAMAccountName?sub?(objectClass=*) AuthLDAPBindDN [email protected] AuthLDAPBindPassword binduserpassword [/Location] [Location /repos/test] DAV svn SVNPath /var/svn/repos/test AuthName "SVN repository for test" Require ldap-group CN=test,CN=ProjectGroups,DC=mydomain,DC=com [/Location] When I'm using "Require valid-user" everything goes fine, "Require ldap-user" also works. But as soon as I use "Require ldap-group" authorization fails. Trere are no errors in apache logs, but Active Directory shows folowing error: Event Type: Information Event Source: NTDS LDAP Event Category: LDAP Interface Event ID: 1138 Date: 10/9/2010 Time: 1:28:52 PM User: MYDOMAIN\binduser Computer: COMP1 Description: Internal event: Function ldap_compare entered.

Additional Data Error value: 2 0000208D: NameErr: DSID-031001CD, problem 2001 (NO_OBJECT), data 0, best match of: 'DC=mydomain,DC=com' I'm confused by this problem. What I'm doing wrong?

How to setup Joomla CMS as a backend for iPhone app

- by srik

I would like my iPhone app to get dynamic content off the net. This content should be managed using a CMS. I have gone ahead and installed Joomla on my server and will be using the Joomla web interface to create and manage content. I would now like the iPhone app to login to my server and fetch the content. I do not want the complete web pages for my iPhone app. Instead, I want the content in the form of XML or JSON or some serialized format so that I can use the data in a custom layout native to the app. So I am looking for 2 things in particular: 1. How to setup HTTP based authentication for my iPhone app to access data from my server. 2. How to access the content in a serialized format (XML, JSON etc) Are there plugins/extensions/components I can use to achieve the same. Any advice on how this can be achieved would be helpful. I am completely new to setting up/using CMS.

Utilities for finding x/y screen coordinates

- by slothbear

I have an application that needs the user to enter the x and y location of a couple of items on the screen. [Yes, this is crap and I'll replace it, but for now...] On Mac OS X, I'm using Snapz Pro X. When I choose to take a snap of a selection, the interface displays the mouse cursor location. This is OK for my personal use, but I can't ask users to buy a $69 program for this function. I thought I had a solution with the built-in program "Grab", but it reports the coordinates from the bottom left, and I need it from the top left. I don't have access to Windows; not sure what to use there. I've not even been able to come up with good search terms since mouse and coordinates and x/y are so common. Ideas are welcome there. Extra credit: same x/y finder for Linux. A Java program would be OK too, since the main application is in Java.
