• Host name change breaking http? Fedora

  - by Dave

  OK so I have been messing around on my development server. It has been a while since I have had my head in linux and I suspect I have broken something. I have SSH running and that is working fine. I also have HTTP and I had FTP running also. Earlier today I decided I wanted to rename the machine so I updated the /etc/hosts file and /etc/sysconfig/network. I also changed the server name in the httpd.conf. I rebooted the machine and reconnected to SSH fine. Later I was messing around with the FTP service (trying to tighten up the user security) and when i tried to connect remotely to FTP no joy, it said cannot connect. I thought that was weird but had planned to remove ftp as we will be using github so removed ftp and moved on. Then I tried to connect to the website but major fail. even connecting to the IP address is failing. I used lynx to connect to the localhost and there was my site so something going on at server level. I thought maybe something up with iptables but I have not changed them but tried adding http but still no joy.

Any ideas?

• Applications randomly alt-tab? (especially full screen games)

  - by Henry Scotts

  I'm not sure when this began, how it happens, or why it happens, but it is quite bothersome and apparently random. Just randomly throughout the day my computer will just go to the desktop. I could be in a full screen game and it will just immediately alt tab and present the desktop. Or I could be watching a movie and this happens. Sometimes it happens once every three hours and other times (just today actually) it did it twice in the span of 30 seconds. I am positive I am not pressing a hotkey because I launched a game, sat idle, and noticed it alt tab while cleaning up around my room after about 20 minutes. Sometimes it goes days without this happening. Specs: Windows 7 Ultimate 64 Bit, 10 gigs of RAM, GeForce GTX 260, Intel Xeon CPU. I also have basically nothing running when it happens other than the game and FireFox. My FireFox add-ons: Adblock Plus, Download Statusbar, Firebug, FirePHP, lazarus form recovery, tree-style-tabs, yslow. I doubt FireFox is causing the issue but I figured I'd include it anyway because it is the only application I have running when it happens. As for user processes I have running: VCDDaemon (context menu for virtual clone drive), razerhid (mouse), OSD, taskhost, dmw (desktop window manager), anyfullscreengame, audiorepeater, netsession_win, explorer, razerofa, tsvncache, firefox, plugin-container, and EKIJ5000MUI (printer). Whew. Okay. That was a lot of information. If someone could diagnose this I would be most grateful for this has been around with me for years.. Thanks for reading! PS: I doubt it's a virus because I never download illegal software and pretty much only browse Reddit and Stackexchange and play games. If it was a virus it would be a pretty lame one.. Hah..

• Ubuntu purple splash screen with blinking pixels?

  - by joxnas

  I had ubuntu 9.10 I upgraded to 10.04 after solving some problems (freeze at boot). Since then, I don't have the ubuntu's logo showing up when I boot, but a purple screen with some blinking pixels. I didn't care much about it... but today my computer took too long at that screen (normally it was just 1/4 second, but today it was like a minute..). And it happened like 4 or 5 times in a row (Only at the 5th time I realised that it was not freezing up, but it simply would took more time) After a reboot, it is again 1/4 second of purple screen but I don't want this problem to return.. so I want to get rid of the purple screen (I think it is an indicator of the problem) Well, I already installed the graphic drivers (going to system admnistration hardware drivers). But it didn't solve anything. (I don't know if it is even related) I searched in google, found something old (2006) and I think it maybe has some relation with my problems .. http://ubuntuforums.org/archive/index.php/t-294692.html But couldn't understand the conversation (i'm a linux novice) Sorry for my horrible english.. I would appreciate any help! My hardware: ATI Mobility Radeon 4650 HD P7450 2.13Ghz Core 2 Duo

• Periodic internet connection drops

  - by sterlingholt

  My setup is a dsl modem, and a dlink di 524M router. I'm also using a Witopia VPN which runs through OpenVPN. I've been having trouble with the internet connection dropping very frequently. It comes back shortly, without even a router/modem/computer restart. This happens as frequently as every ten minutes. Occasionally (not often) it will last as long as an hour or two without dropping. When it drops, I can get it back almost immediately by clicking Reconnect in the OpenVPN GUI and letting that do it's thing. It's worth noting that I'm in China. Calling support is a bit difficult because of that. Also I don't really understand all of the router's software, although I've got it generally figured out. I've tried a bunch of stuff, attempts to diagnose and/or fix the problem. No success with any of the following: I've power cycled both the modem and the router. I've tried an ethernet connection to the router. I've connected without the VPN. I've disabled IEEE authentication on all connections. I've checked for viruses. I've tried lifting it off the ground so as to prevent overheating.

• How to play 24 fps video smoothly on a 60Hz display?

  - by netvope

  I use mpc-hc to play videos on Win7 x64. With the default settings (#1), video playback is great most of the time. But for panning shots, playback is not smooth. I stepped through the video frame by frame and found that the panning movement is smooth (e.g. each frame shifts horizontally by 10 pixels), so the problem is how the 23.976 fps video is interpolated to 60Hz. The judder looks like what would be caused by a "2:3 pulldown", where the frames are played unevenly like: frame 1, 1, 2, 2, 2, 3, 3, 4, 4, 4, etc (#2) Using "optimal renderer settings" (#3) instead of the default disables the Aero theme and causes tearing. Setting my LCD display to 50Hz may have improved the judder slightly (but I can't really tell). My display does not support 24Hz or 48Hz, and forcing them in the Nvidia control panel gives blurry screen. I've tried other video players (VLC and KMPlayer), the ReClock Directshow Filter, video files from different sources (#4), turning on/off DXVA, and a computer with a different GPU, but the judder in the playback is similar. None of them solved the problem. So, how can I play 23.976 or 24 fps video smoothly on a 60Hz display? I think a video player could make the video smoother by doing linear interpolation, such as: 1. 100% frame 1 2. 60% frame 1 + 40% frame 2 3. 20% frame 1 + 80% frame 2 4. 80% frame 2 + 20% frame 3 5. 40% frame 2 + 60% frame 3 6. 100% frame 3 7. 60% frame 3 + 40% frame 4 .. etc Can any existing video player do this? Footnotes: (#1) Video renderer: EVR Custom Pres. (#2) This example converts a 24 fps video into 30 fps (#3) View Renderer settings Reset Reset to optimal renderer settings (#4) The files I have are all H.264 mkv files, but I don't think the file format/encoding matters.

• Doing port forwarding and then using it from within the internal network

  - by Ram Rachum

  We all know that by doing port forwarding on the router, computers from outside the network are able, on the specified ports, to access internal computers by targeting the external IP. I'm now replacing a TP-Link router with a D-link VDSL N 6740U router, (and copied over all the settings,) and I've noticed that one thing stopped working: With the TP-link router, you could access those port-forwarded computers from within the network, using the external IP, and they would be forwarded to the relevant computers. With the new D-Link router, it doesn't work. You might be wondering, why would you want to use the external IP and port forwarding when you're inside the internal network anyway and can just access the internal IP? One example for why this is useful: You have an iPhone app that connects to a service on an internal computer. The iPhone app knows to connect to the external IP. When we put that iPhone inside the internal network (via WiFi), it suddenly stops working, because it can't access the service from the external IP anymore. Is it an inherent property of D-Link routers that they do not allow accessing internal servers from inside the network by targeting the external IP? Or is there a way to make it work?

• Error 0x80073cf9 when installing or updating apps from windows store

  - by cmorse

  On my Windows 8 desktop I keep getting error 0x80073cf9 when I try to install or update an app from the windows store.

• How do I find my missing songs from last.fm?

  - by duality_

  My disk failed with all my music with it, lots of them. But luckily, I scrobbled every song to last.fm. I am looking for a way to scan my disk for my songs and check last.fm and tell me which songs are missing from my disk that are present on last.fm. So to recap: I would need to log into my last.fm account and compile a list of all the songs I have scrobbled and then scan my computer for missing songs. Is there a program or script that does this? I don't mind it being a shell script even. Edit: I know this is possible because I came close to this a little time ago. I created a PHP script (web page) that got all my songs through Last.fm API and then went through my files on disk and read their id3 tag. I got very close: the program showed missing songs, but there were many small issues (id3 reading was buggy, tags had different data, etc.) that required more programming time that I didn't have.

• Terminal Server in Windows Server 2003

  - by Hemal

  I have a confusion regarding what I am doing here. At present I have a Windows Server 2003 server with SP2. I have assigned RAS/VPN server role to it (through Manage my server wizard) and in my router, I setup the IP address of my RAS/VPN server as PPTP server. Staff leave their workstations ON all the time and access them from home through RDP. They first connect thorugh VPN & in the RDC they simply type their respective IP or computer name to access the office network from home. Everything works fine so far except: Staff have to leave compuers always ON in the office Speed is very slow depend how many staff members access the VPN network I was told to install and configure Terminal service to improve this situation. I already added TS Role in the server but I don't know how to clients can access the TS server from home or remote location. I really appreciate any good links or guidence from the experts in this group regarding this. Thank you in advance for any replies!

• Why is the Windows 8 recycle bin using more space than it is allocated?

  - by oldmankit

  I ran WinDirStat to scan the contents of my hard drive. I was surprised to see that the $RECYCLE.BIN folder on my D: drive takes 26 GB of space. I emptied the recycle bin, refreshed the folder in WinDirStat, but it still takes 26 GB of space. I reduced the Maximum size of the recycle bin for this drive to 10000 MB for the main user of this computer, and disabled the recycle bin for the other user, and refreshed the folder in WinDirStat, but it still takes 26 GB of space. I ran (in an elevated window) rd /s D:\$Recycle.bin, and refreshed the folder in WinDirStat, and finally it became empty. Why was it taking up space even after I emptied it? Why was it taking more space (26 GB) than the maximum allowed amount (10 GB)? Update: After six months of using Windows (no re-install and no changes of settings related to the Recycle Bin) I used WinDirStat to check how big D:\$RECYCLE.BIN has become. It is now 29 GB. In Recycle Bin Properties, I select drive D, and it is still a custom maximum size (10000 MB).

• Live Screencast under Linux

  - by OmnipotentEntity

  I was having some difficulty with running a Live Screencast under Linux.

• IP queue buffer

  - by summerbulb

  I seem to have an issue with IP queue. I have a linux machine that I am using to run some experiments. The linux machine is configured to be a router, having two NICs, connecting two other computers, and managing their network traffic. All incoming packages are captured, using iptables, and analyzed by a C application. The application analyzing the packets has a built-in delay, as part of the experiment. So I have one very fast computer sending packets through my linux-router and a (relatively) slow linux-router that analyses and deals with the packets, one by one. This situation leads to the fact that when I fire up a sender application on one of the computers connected to the linux-router, my IP queue on the linux-router gets filled up (almost) instantaneously. The IP queue's max length is currently set to 1024, and if it overflows, the packets are dropped. This is expected and i'm OK with it. But, (and this is where it gets interesting), every now and then I get the following error: "Failed to receive netlink message: No buffer space available" At start, I thought this was due to the IP queue overflow, but after some analysis i found that sometimes I get the error even if the IP queue buffer did not overflow, and sometime I DON'T get the message even though the buffer DID overflow. When I run > cat /proc/net/ip_queue, I get the following table (also used to monitor the IP queue overflow): Peer PID : 27389 Copy mode : 2 Copy range : 65535 Queue length : 0 Queue max. length : 1024 Queue dropped : 1166875 Netlink dropped : 2916 Looking at the last two values, Queue dropped seems to refer to packets that did not manage to get into the IP queue because the buffer was full. I can see this value rise as I bombard the linux-router. Netlink dropped ( as it's name implies :) ) seems to have to do with the error i'm getting. I did my best to search for material on this error, but wasn't able to find anything that seemed to point me in the required direction. Bottom line: Why am I getting this error and what can I do to avoid it?

• How to serve media across home network?

  - by TK Kocheran

  I'm looking to share my media across my home network. Router fully supports running a DLNA server, but I don't know if it'd be better to run the server from my main server computer instead of from the router, as the router would have to operate off of a network share and my server can operate directly off of the files. Here's what I need to serve, in order of importance: ISO 1:1 DVD rips (4-8GB files), MP4/H.264 encoded videos, MKV videos, MP3 files, JPEG/CR2 images. Maybe I'm completely ludicrous for wanting to push full DVD files across my network, but in reality, I would assume that only the parts of the actual file needed (ie: menu, main video payload for main title) would be served at any one time. Plus, encoding takes time and precious disk space, so why not stream it 1:1 ;) Does anyone know of the best way to accomplish this? Main goal is to serve it to Logitech Revue downstairs and secondary goal is to serve it to other computers in the house. For music, I assume I could run a DAAP server, but I don't think that the Revue supports that (and I can't exactly throw together an app that does it just yet).

• Sharing a folder with Nautilus and NTFS external drive gets errors

  - by TheLQ

  I am trying to share a folder in Lubuntu over a network that's on an external NTFS drive. Due to the system that I have (rotating backup disks) this is probably the second time that the drive would of been mounted. Its manually mounted with a simple (for example) mount /dev/sdb1 /media/BACKUP On an internal NTFS disk I have successfully setup a network share and can access it. However on the external disk I can't from any other Windows computer. When setting up the share Nautilus said that it needs to change the other's permissions to allow for other users to write. However afterwords its still blank. Changing it to Read and Write just changes back to blank. Chowning the entire /media folder recursively and trying didn't work. Running PCManFM as root and changing didn't work. Adding "public=yes" to smb.conf and restarting didn't work. I'm out of idea's on what to do. What's weird is that it worked just fine on an internal NTFS disk, so why not the external one? Any solutions need to be able to managed inside of a gui (preferably Nautilus) as the person managing the machine isn't as tech savvy. Thanks

• Has anyone had luck running 802.1x over ethernet using the stock Windows or other free supplicant?

  - by maxxpower

  I just wanted to see if anyone else has had luck implementing 802.1x over ethernet. So here's my basic setup. Switch sends out 3 eapol messages spaced out 5 seconds apart. if there's no response the machine gets put on a guest vlan with restricted access. If the machine is properly configured it will authenticate and be placed into a secure vlan. About 10% of my windows xp users are getting self assigned 169 addresses. I've used the Odyssey Access Client and it worked without a hitch. I'm using the setting to automatically use the users windows login to authenticate, but it's workign on 90% of the machines so I don't think that's the issue. Checking the logs on the dc it seems that the machines are trying to authenticate with computer credentials even though they are configured not to. I'm running Juniper switches with IAS for radius. I have radius configured for PEAP and MSvhapv2. Macs and linux boxes seem to have no issues authenticating. One last thing to add If I unplugging the ethernet cable and plug it back in usually resolves the issue, but I'd hardly call that acceptable for production. Kinda long winded and specific for a discussion, but just want to see if anyone else has had similar issues or experiences, or if anyone knows of a free XP supplicant that actually works with 802.1x over ethernet.

• Strange Internet Connection issues

  - by Nodren

  I'm attempting to troubleshoot problems with a laptop computer(HP 8510w) while it's connected to a server of mine via Remote Desktop. I double checked all the settings on the win2k3 server for remote desktop to verify that remote desktop isn't what's causing the disconnect issues, and other people using different computers/laptops can all connect to remote desktop correctly with no issues. These problems happen specifically when the laptop is connected via wifi(several different wifi sources, so it's not an ISP issue) as well as connected via a Verizon data card. However there's no network downtime when the laptop is resting in the docking station and plugged into the network with the remote desktop server. These problems have also only recently occurred since a recent hard drive failure in which a new hard drive was purchased and the laptop had a fresh install of windows xp professional. There's no special software used on this machine, just office 2003. So my question is, what could cause two types of internet access to fail while other types do not? If it is infact related to the win2k3 server, why is this particular laptop getting disconnected when others are not and are all on at the same time?

• Can't display RSSI values in Wireshark

  - by Giovanni Soldi

  I am trying to analyze the up-link Wireless traffic generated by my Sony Ericsson phone and captured by my D-Link router, on which I installed the DD-WRT firmware. To do this, first I log in the router and enable the prism0 interface by typing the command: wl -i eth1 monitor 1 and then I start to capture the packets by typing: tcpdump -i prism0 ether src xx:xx:xx:xx:xx:xx -s0 -w /tmp/smbshare/sony_ericsson_test.pcap where xx:xx:xx:xx:xx:xx is the MAC address of my Sony Ericsson phone. After a while I transfer the sony_ericsson_test.pcap file to my computer and open it with Wireshark program. In order to display the RSSI values I follow this procedure: Edit - Preferences... - Columns - Press "Add" button - As "Field type" I choose "IEEE 802.11 RSSI" and finally I choose name "Power" and click on "Apply" button. The problem is that the column "Power" is empty with no RSSI values. Does Anyone has a clue on why are RSSI values not displayed? Maybe I am missing a passage. Looking forward to hearing from anyone of you! Thanks in advance for your help!

• Immediate logout after login with PAM, Kerberos, and LDAP

  - by Dylan Klomparens

  I've set up remote login on a computer using Kerberos and LDAP. I've also configured NFS to mount onto /home so that the user's home directory is the same wherever they login. Kerberos authentication seems to work fine. I can get a ticket using kinit user1 (assuming user1 is a remote user) and see the ticket with klist. I'm pretty sure LDAP is working because I see the proper output from getent passwd, which lists all the remote users. The contents of /home are present when I list the files. The problem is: when I try to login as a remote user the session is immediately ended. Why is it not letting me stay logged in? Here is the output from /var/log/messages after a login attempt: # /var/log/messages: Oct 9 10:57:53 tophat login[6472]: pam_krb5[6472]: authentication succeeds for 'user1' ([email protected]) Oct 9 10:57:53 tophat login[6472]: pam_krb5[6472]: pam_setcred (establish credential) called Oct 9 10:57:53 tophat login[6472]: pam_krb5[6472]: pam_setcred (delete credential) called EDIT: The distro is openSUSE.

• BIOS not detecting working SATA hard drive.

  - by Evan

  Some time ago my power supply died. It's a long story from then till now, but the important bit is that I ended up with a new hard drive and a new power supply. I tested to see if my original hard drive was still alive, and it booted and worked perfectly until I turned it off. When I started it again it would not boot. I bought new SATA cables, assuming that the one I had was not seating properly (it was cheap and wobbly), but no dice. Upon start-up I am presented with a message telling me to insert boot media into the selected drive or add a drive and restart. Neither the new or the old drive is detected by BIOS, my Vista install disk, or from my bootable Linux USB drive. When I remove all of the RAM the computer ceases outputting visual information, and upon reinstalling the ram and starting up again gives me a "failed overclock" error. So, does anyone have an idea as to what might be going on? I'm completely lost at this point.

• linux container bridge filters ARP reply

  - by Dani Camps

  I am using kernel 3.0, and I have configured a linux container that is bridged to a tap interface in my host computer. This is the bridge configuration: :~$ brctl show bridge-1 bridge name bridge id STP enabled interfaces bridge-1 8000.9249c78a510b no ns3-mesh-tap-1 vethjUErij My problem is that this bridge is dropping ARP replies that come from the ns3-mesh-tap-1 interface. Instead, if I statically populate the ARP tables and ping directly everything works, so it has to be something related to ARP. I have read about similar problems in related posts, and I have tried with the solutions explained therein but nothing seems to work. Specifically: ~$ grep net.bridge /etc/sysctl.conf net.bridge.bridge-nf-call-arptables = 0 net.bridge.bridge-nf-call-iptables = 0 net.bridge.bridge-nf-call-ip6tables = 0 net.bridge.bridge-nf-filter-vlan-tagged = 0 net.bridge.bridge-nf-filter-pppoe-tagged = 0 arptables and ebtables are not installed. iptables FORWARD is all set to accept: Chain FORWARD (policy ACCEPT) target prot opt source destination The bridged interfaces are set to PROMISC: ~$ ifconfig ns3-mesh-tap-1 Link encap:Ethernet HWaddr 1a:c7:24:ef:36:1a ... UP BROADCAST PROMISC MULTICAST MTU:1500 Metric:1 vethjUErij Link encap:Ethernet HWaddr aa:b0:d1:3b:9a:0a .... UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 The macs learned by the bridge are correct (checked with brctl showmacs). Any insight on what I am doing wrong would be greatly appreciated. Best Regards Daniel

• Not able to access external Hard disk

  - by Jash Jacob

  I have a 1TB External Hard drive which I'm currently not able to access. When I open the External drive in Finder, It shows it's empty. When I use the option to "Get Info", I get the dialog box stating it has about 300GB Free. Tried to get into the External Drive using Terminal, I had no luck. Checking in Disk Utility, It showed that I have many number of files but ZERO folder. I tried to "repair disk", in the process the external Drive got unmounted in between the process. I checked this drive on Windows. I was able to open almost all the folders but I wasn't able to copy anything onto the external drive. One folder caused my windows computer to hang, So i connected the drive back onto my MacBook Pro and tried to access the drive through terminal (this time it worked!) and then I tried to delete the folder with rm command, I got an "input/output error" What should i do to recover the files in that folder? How can i access my external drive on my mac

• Content not being compressed even though I'm using zlib in php.ini

  - by Tola Odejayi

  I've edited my php.ini file so that it has these two entries: zlib.output_compression = On zlib.output_compression_level = 4 However, after restarting apache, when I request php pages, the headers returned in the response indicate that my server is still NOT serving compressed pages (here are selected headers as viewed using Chrome's Network feature): Cache-Control:no-cache, must-revalidate, max-age=0 Connection:Keep-Alive Content-Type:text/html; charset=UTF-8 Date:Mon, 17 Sep 2012 23:46:13 GMT Expires:Wed, 11 Jan 1984 05:00:00 GMT Last-Modified:Mon, 17 Sep 2012 23:46:13 GMT Pragma:no-cache Proxy-Connection:Keep-Alive Server:Apache/2.2.21 (Unix) mod_ssl/2.2.21 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.17 Transfer-Encoding:chunked Via:1.1 XXX-PRXY-07 X-Powered-By:PHP/5.2.17 What might I be doing wrong?

• How to set up a easy-to-use proxy for the whole system with WinXP client and server?

  - by Pekka

  I am working together intensively with a colleague on the Canary Islands. We speak through live messenger and work together using a RDP software. She has frequent problems with connections to certain big-name and small-name sites (amongst others live.com, google.com, gmx.de) very likely to be caused by the spanish provider (the connections simply time out, this has been going on for weeks already). I have been thinking about setting up my computer as a proxy to make these connections work. I have a DSL connection and am behind a NAT capable router that I control. Does anybody know a simple, "one-click" way to transport ALL network traffic through a remote proxy? Without having to set proxy settings for each application that uses the internet? VPN is not an option, because I am behind a firewall that supports protocol 47 and such, but I have never succeeded in getting an incoming VPN connection to work. I can however redirect normal traffic using NAT. A VPN solution that does not need strange protocols would also be an option.

• Change Windows Authentication user for Sql Server Management Studio

  - by Asmor

  We're using Sql Server 2005 with Windows Authentication setup. So normally, when you log in using e.g. Sql Server Management Studio, it forces you to log in at MACHINE_NAME\Username. Anyways, on this one particular computer, the person said they had to make a new account called User01 to do something and showed me where she'd created it under security in the "master" system database. And so now when she logs in, it's listed as MACHINE_NAME\User01 (not the actual Windows user name). It's still set to Windows Authentication, though, and I'm unable to change the login name. Now here's where the real problem comes in... I didn't realize that she was being logged in under this user name at the time, and I disabled it to see what would happen. Now I can't log into the server under her account. I created a new account in Windows called test, and as expected SSMS had the username as MACHINE_NAME\test, and I was able to log in fine. However, the area where the User01 account was listed is not visible to me as far as I can tell and so I can't reenable it. I also tried running the following query: alter login User01 ENABLE And got this error: Msg 15151, Level 16, State 1, Line 1 Cannot alter the login 'User01', because it does not exist or you do not have permission. So in a nutshell, ideally I'd like to reenable User01 somehow, just to get things back to where they used to be. Failing that, how can I force SSMS to log in using the Windows account name as it should be, rather than trying to use User01?

• Can I connect a Playstation 3's HDMI output to my monitor's DVI-D input? [migrated]

  - by HankJDoomstorm

  I'm attempting to connect my Playstation 3 to my computer monitor. The monitor has a DVI-D (dual link) input, so before distinguishing between the different DVI varieties, I bought a DVI-I (dual link) to HDMI converter that won't fit into the port on the monitor (not only that, there isn't enough physical space in the back of the monitor to fit that much stuff before it hits the bottom of it). So I grabbed a DVI-D (single link) cable and got a female-to-female DVI-I coupler, and plugged the DVI-D cable into the monitor and the whole mess of converters. The end result was HDMI to DVI-D single link, but my monitor isn't receiving a signal on its digital channel. (For clarity's sake: DVI-D DL input on Monitor, DVI-D SL cable, DVI-I DL female-to-female coupler, DVI-I DL to HDMI converter, HDMI output on PS3) I don't know much about this stuff (obviously), but my educated guess is that the bandwidth of the PS3 is too high for the DVI-D Single Link cable, so nothing's getting through. Will replacing the single link cable with dual link resolve this? If not, is it possible at all? Oh, I should mention I'm aware I won't get audio through the monitor. I have an RCA to 3.5mm converter for that.
