• I need a way to read feeds that meets the following requirements

  - by Daddy Warbox

  Requirements: Can be overlaid over other windows. Can be moved and resized freely. Adjustable refresh times and/or a reload button. Text-only is fine. I will need to open hyper links, though. Simple and cheap free. Offline caching. If you know of a program that does all of this, can you tell me what settings I need to adjust to get it to do this? Thanks in advance.

• Boxee on Dell 32in TV causes headaches, how to troubleshoot?

  - by brown145

  I have revamped an old pc, installing 4GB ram and a 256MB video card so that I could run Boxee to a Dell W3200 series TV that came with my apartment. It is connected via VGA, resolution is 1360x768, 24bit color, 60Htz refresh rate. Unfortunately, every time I use it I end up with a headache after less that 30 min. I have had my eyes check recently, and am able to play xbox (connected via hdmi) on the same TV without problems. What are the potential causes? My system seems to well meet or exceed the min requirements for boxee, XP, AMD Atholon 64 X2 Dual Core, 4GB RAM. Could it be the VGA cable? What is the most cost effective way to trouble shoot?

• How to know my wireless card has injection enabled?

  - by shrimpy

  I am playing around with aircrack. And was trying to see whether my wireless card on my laptop can pass the injection test And I end up seeing the following... does it mean my wireless card is not able to run aircrack? root@myubuntu:/home/myubuntu# iwconfig lo no wireless extensions. eth0 no wireless extensions. eth1 IEEE 802.11bg ESSID:"" Nickname:"" Mode:Managed Frequency:2.437 GHz Access Point: Not-Associated Bit Rate:54 Mb/s Tx-Power:24 dBm Retry min limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=5/5 Signal level=0 dBm Noise level=-57 dBm Rx invalid nwid:0 Rx invalid crypt:781 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 root@myubuntu:/home/myubuntu# aireplay-ng -9 eth1 ioctl(SIOCSIWMODE) failed: Invalid argument ARP linktype is set to 1 (Ethernet) - expected ARPHRD_IEEE80211, ARPHRD_IEEE80211_FULL or ARPHRD_IEEE80211_PRISM instead.

• scp using a password on the command line

  - by spierepf

  I am trying to write a script that will deploy a build created on my desktop machine (windows/cygwin) to a machine in my test environment (linux). I would like to use scp to copy the build to the target machine. The only account on the target machine is root, and I cannot create a special user for this task. The root user is unable to log in using an ssh key (I suspect that this is configured on the ssh server, but I do not know which configuration options control this). At any rate, I cannot change the configuration of the ssh server. My desktop machine uses Cygwin, and I have ssh installed. What I need is the command-line-fu that will allow me to put the password on the command line. I am aware of the dangers of having a plaintext password in a shell script, but that is not a concern here.

• Windows screen resolution change: lengthen timeout

  - by Jonathan J

  Occasionally I need to change the screen resolution of the console of a Windows virtual machine using XenCenter. When you attempt this change, Windows will revert if you don't accept the changed resolution within 15 seconds of clicking 'apply.' (Normally, this is a good thing.) The problem is that if I have a slow connection between XenCenter and the Xen hypervisor, the virtual console display may not refresh quickly enough to allow me to respond within 15 seconds. As a result, I can't change the resolution, even though the new resolution is valid. Is there a way to increase the timeout before reverting to the original display resolution?

• Connecting to iSCSI Target

  - by Joost Verdaasdonk

  I've installed Microsoft iSCSI Software Target 3.3 on a server 2008 R2 machine and created a new iSCSI Target. In the target I created a new Virtual Disk. From another server I started iSCSI Initiator and in Targets | Target I typed the IP of the Target. (Also tried DNS name.) But when I click Refresh I never see the target. Through googling I found this Youtube tut from a French guy doing pretty much what I did (only difference is I'm in a domain). I first though that maybe Port 3260 was closed but its not I can telnet to it. Also disabled all firewalls to see if that was blocking anything... No luck so far. Does anybody know of possible reasons why I can't connect to the iSCSI Target? If I can provide more info please let me know what's needed? Extra info: I've used this tut to set things up.

• Database for heat tolerances of various cables?

  - by I. F.

  Is there any kind of unified database of heat tolerances for networking cables? I've been setting up a number of home/small office networks lately and as a mostly-amateur I could really use some information on what is safe to run behind a radiator, next to a steam pipe, etc. The question I'm up against at the moment is: Can I run normal RJ11 phone line cable (from DSL modem to phone jack) behind a steam radiator without risking a fire? Unlike cat5, I could not find published standards for these, so I'm turning to experts with more experience. This is a cut-rate show. Do I go out and buy more cabling, and if so which, or use the spare that I have?

• How to enable the flash player plugin in IE8?

  - by Nik Reiman

  I updated to IE8 the other day on my Vista laptop, mostly because Windows Update kept bugging me about it. As a Chrome user, I don't really care so much about IE8, but I do have to use it occaisionally to test website compatibility. At any rate, flash seems to be completely deactivated, and I don't see a place to re-enable it anywhere in the preferences. I've done a bit of googling on the issue, but only found information about how to disable flash, not how to actually enable it. I have the flash 10 debug player installed, and it works fine with Chrome and Firefox. What could be the matter?

• How to make sure clients update their browser cache when my website is updated?

  - by user64204

  I am using the HTTP 1.1 Cache-Control header to implement client-side caching. Since I update my website only once a month I would like the CSS and JS files to be cached for 30 days with Cache-Control: max-age=2592000. The problem is that the 30-day period defined by Cache-Control doesn't coincide with the website update cycle, it starts from the moment the users visit the site and ends 30 days later, which means an update could occur in the meantime and users would be running with outdated content for a while, which could break the rendering of the website if for instance the HTML and CSS no longer match. How can I perform client-side caching of content for periods of several days but somehow get users to refresh their CSS/JS files after the website has been updated? One solution I could think of is that if website updates can be schedule, the max-age returned by the server could be decreased every day accordingly so that no matter when people visit the website, the end of caching period would coincide with the update of the website, but changing the server configuration every day goes against one of my sysadmin principles (once it's running, don't touch it).

• IIS + PHP + Page with lots of images = Intermittent 403 errors

  - by samJL

  I am using an up-to-date Server 2008 R2 Datacenter, running IIS 7.5 and PHP 5.3.6/FastCGI On PHP pages with lots of images (60+), some of the images fail to load It is not always the same images-- on each page refresh an image that worked previously may not load, while an image that did not now does Looking at the Net tab in Firebug reveals that the failing image requests are 403 errors All of the images are located on the server in question, and the images directory has the correct permissions I believe this problem is the result of a limit on requests All of my attempts at researching this problem point to maxConnections setting in IIS, yet mine is set at the highest/default of 4294967295 (maxBandwidth too) I am also running a ColdFusion site on the same IIS installation, and it does not suffer from 403's on pages with lots of images I am left thinking that there is another connection limit (in PHP or FastCGI?) overriding the IIS connection limit I don't see anything that looks like a request limit in the php.ini, what am I missing? Any help would be appreciated, thank you

• MySQL 5.0 Unavailable but still working every monday morning

  - by user1578031

  So I have a MySQL server with 4-5 databases and every monday morning, I can't login with PHPmyAdmin or the cmd line tools or options and the funny thing is the connection can be made later in the day around 3:30 - 4PM. I can't replicate the issues on any dev boxes and cant upgrade to 5.5 for a number of reasons. I want to try and poll the sql databases with a simple script and just connect to it and then disconnect. I'm not very good with SQL but would like to know if anyone could help with a script which I can automate to run sunday every 30mins or so, to see if the issue can be stopped by the database being connected to over the very quiet period of sunday... After this im out of ideas and have to wait for the HW/SW refresh to get 5.5 on there...

• Keyboard Pressing Application

  - by Click Ok

  Imagine that problem. When you play some games, sometimes happens situations like "press quickly the X key to escape from ropes" or "press quickly the X key to fill the rage gauge", etc. Of course, that kind of game destroy keyboards, joysticks, mouses, etc. I would like to know about programs (preferentially free) that, by example, will press the 'x' key in intervals of, by example, 300ms. Remember that the built in Windows "keyboard repeat rate" doesn't works for games. When you press (and hold) somekey in the game, the key is not repeated as in default Windows Applications. Thanks!

• Log with iptalbes which user is delivering email to port 25

  - by Maus

  Because we got blacklisted on CBL I set up the following firewall rules with iptables: #!/bin/bash iptables -A OUTPUT -d 127.0.0.1 -p tcp -m tcp --dport 25 -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --gid-owner mail -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --uid-owner root -j ACCEPT iptables -A OUTPUT -p tcp -m tcp --dport 25 -m owner --uid-owner Debian-exim -j ACCEPT iptables -A OUTPUT -p tcp -m limit --limit 15/minute -m tcp --dport 25 -j LOG --log-prefix "LOCAL_DROPPED_SPAM" iptables -A OUTPUT -p tcp -m tcp --dport 25 -j REJECT --reject-with icmp-port-unreachable I'm not able to connect to port 25 from localhost with another user than root or a mail group member - So it seems to work. Still some questions remain: How effective do you rate this rule-set to prevent spam coming from bad PHP-Scripts hosted on the server? Is there a way to block port 25 and 587 within the same statement? Is the usage of /usr/sbin/sendmail also limited or blocked by this rule-set? Is there a way to log the username of all other attempts which try to deliver stuff to port 25?

• Good speedtest results, but web pages don't load

  - by dmt0

  I have strange connection problems. Ping and download times are good - speedtest.net showed ping 65ms and download 2.17Mbps. Torrent is working well, giving me up to 300MBps. Webpages are loading very poorly though. They are timing out each time - I'd have to refresh 4-5 times to get any simple page to load. It has been happening consistently for the last few days. Same with different browsers on different machines (same network), Windows and Linux. There is no proxy in the browser. Is there any setting in Windows or in a browser that I can change to help this? Some background: I live on this island in Thailand, where internet connection is through radio to another island and than to mainland - it's very weather dependent, but generally OK. As I mentioned, ping is good. Any input is very appreciated.

• Windows 7 Intermittent Connection Issues (Continuously "identifying")

  - by andrewktmeikle

  I have an issue solely with my desktop windows 7 machine on my network (the network has multiple different devices, on the same and different operating systems) and the issue is that irregularly, although sometimes frequently, I briefly get disconnected from the internet (briefly is for around 5-10 seconds). However, I never loose the bars on the wifi thing, eg I don't get the yellow triangle, but it goes to the identifying stage and then reconnects. The reason I noticed the problem was when I was streaming music it would stop and I would refresh the page and it would start working again ( turned out it was because it took that amount of time to get connected again). So my question is, what would cause the intermittent issues and start the "identifying" process again. I don't think its my router, because no one else is having problems, so the other option is that its a problem specifically with my machine. I'm connecting to a Netgear DG834GT router, and I'm using a Edimax Wireless-N150 USB Adapter. Anyone have any ideas?

• How can I make Picasa see changes I make to photos using jhead?

  - by Dan

  Last fall I forgot to set the time on my camera back an hour. I used jhead to change the time in the EXIF data: jhead -ta-1 IMG_1177.JPG but Picasa didn't notice. OS is Windows XP. If I right-click the picture in Picasa and choose Properties, in the top section of the dialog it shows "Date: 3/6/2010 11:22:54 AM" but in the Property|Value section it shows "Camera Date | 2010:03:06 10:22:54". I tried using "Refresh thumbnails" but that didn't help. Picasa notices other changes, like if I edit the photo in the Gimp or change the filename, but for some reason it doesn't notice this change.

• Extract photo stills from .vob files

  - by Eric Rath

  My parents had all the family slides scanned by a photo lab. The lab returned the digital photos on two DVDs as movies; there's some stock music over a slideshow with fades between each photo. The discs contain only a handful of files, including some very large VOB files. I'd like to extract these photos and import them into iPhoto. I saw this answer about capturing stills, and that might work if I can figure out the right offset from the beginning and the right capture rate. But this approach seems very error-prone for this purpose. Is there a better way? I wish the individual photo files were stored in a directory on the discs, but they're not there.

• When should I use SATA 6gb/s?

  - by Gili

  I purchased a Baraccuda hard-drive (model ST3000DM001) that supports a maximum read transfer rate of 210 MB/s and SATA 1.5/3/6 Gb/s. My motherboard has a limited number of 6 Gb/s ports so I'd like to reserve them for when it's really necessary. When does a hard-drive benefit from a SATA 6 Gb/s port? Doesn't it require a transfer speed of at least 375 MB/s to surpass the limit of SATA 3 Gb/s? Are there any other benefits of SATA 6 Gb/s vs 3 Gb/s ports?

• Data CD for audiobooks?

  - by Marco7757

  I'm trying to burn my .mb4-audiobook files to a CD. I was impressed by the compression-rate (10 hours of audiobook within 150MB?!). The problem now is, that I cannot burn it as an audio CD as these allow only about 80 minutes of audio (audiobook is about +10 hours). I burned them as a data CD now. It works, but, of course, the downside of a data CD is, that not every player (e.g. car, stereo) can play data CDs. What can I do? I don't want to waste 100 CDs on such a simple problem ... is there any way to burn an audio CD? I mean, just regarding the filesize this shouldn't be a problem, shouldn't it? Why is an audio CD only able to play up to 80 minutes?

• File server share access intermittent/slow/machine unstable: win2k8r2

  - by Jack B.

  I have a file server running Win2k8R2 on an older HP DL380G4. It has nothing set up on it other than file sharing. All drivers/firmware/updates installed. The file server is used as a dump for a bunch of test machines - so essentially a lot of small files are being written to it. It was working fine until it started showing the following symptoms: Shares became either very slow/intermittent or could not access them at all. Logging in the the server, you could use it like normal but windows would start freezing and eventually you had to hard reboot it because nothing was responsive. After rebooting, it would work fine for 20min-2hours and then degrade into this broken state again. Some info after investigation: HP Raid Config utility shows the Raid array as functioning properly (RAID5 btw). Event log shows a bunch of DoS attacks from the test machines, saying it has disconnected the connection a. AFAIK (not part of my job) the test machines haven't changed the way they log information to this server or the amount of them hasn't increased. b. Nothing is infected, this server was scanned fully, and the test machines are re-imaged almost daily. Nothing in performance monitor shows as anything being pegged at maximum (CPU/HD/Network/RAM) I installed MS Network Monitor and it is showing a lot of traffic The server was using one gigabit Ethernet connection, I connected the second one as well with the same results. Forgot to add - one of the commonly written to dirs on the share has over 16k subdirs in it, with a crapton of small files within those dirs. Some of the OS instability was slow access to the drive which has this directory - perfmon doesn't show much activity on the HD though so I'm not sure if this crowded dir is the cause. Here is one important fact: I ran into this issue 2-3 months ago, couldn't figure it out, but I had a spare identical machine so I swapped them out (thought it was related to the machine), and now I have the same issue. Also, the computer will be stable if I turn off file sharing. So is the server just getting DoS'd by the test machines? I've never dealt with such an issue. Is instability in the server's OS common when getting DoS'd? Is there anything I can do to confirm this before telling the owners of the test machines to optimize their traffic? (I'm not sure what they'll be able to do). Is there something within Win2k8R2 that can balance the traffic across the two NICs? Any help would be appreciated. Update: Another thought - the drive with the share is RAID5 across 6 SCSI320 300GB HDs. They are near full capacity about 100GB from 1TB left. Could the amount of tiny files could be causing some weirdness with the parity in this array? I think I've read something about this in the past but I'm no expert on RAID.

• Preview.app only auto-refreshes if you alt-tab to it.

  - by dreeves

  I'm working on a program that generates an image. I can keep the image open in Preview and when the image changes, Preview refreshes it, but only when I alt-tab (sorry, command-tab) to it. I'd like to keep the image in view and have it auto-refresh without touching it. Is that possible? (One ridiculous way I've found to do this is with a script that converts the image to a PDF file which I can keep open in Skim.app (a PDF reader) which has that ability.)

• nginx not returning 304 on cached content

  - by Don H

  I'm using nginx as a reverse proxy with an Apache back-end handling some PHP files. The files return the right expiry headers and proxy_cache does a good job of caching them, but I've noticed that the cached content returns a 200 on every refresh, when it might be more efficient to return a 304 on the cached files. The files in question are generated by PHP. The urls do not have .php in them as they've been prettified. Any idea why nginx might not be returning 304 on repeated visits to a cached PHP output? To clarify: It's using proxy_cache for caching dynamic PHP pages (not static html pages generated by PHP). I'm setting expires headers in the PHP file of time + 24 hours. With that in mind, I was hoping nginx would be able to then return 304s on its cached versions during that 24 hour window.

• VPS stops responding every now and again

  - by Or W

  I have a Linode vps that I use to host some of my websites on. It's Ubuntu based and it's up to date in terms of all packages. I don't have any cron jobs scheduled or any automatic processes. I host a few (up to date) wordpress blogs there that have very little traffic altogether. Every day (at a different time) my server stops responding, I can't SSH to it, web access is getting timed out and it just dies until I reboot it through the Linode manager. On the linode dashboard I can see that the CPU is not very high (2-3%) Incoming/Outgoing traffic is on 0 and the IO count has a spike just before the server stops responding (SWAP IO is at 2k and IO Rate is at 5k). When I reboot the server everything is just fine. I'm trying to figure out a way to analyze what's going on at these random times where the server freezes up. How can I determine the problem?

• Terminal Server 2003 Gaining Time when Windows 7 Client Connects

  - by Matthew

  A Windows 2003 Terminal Server keeps time perfectly until a Windows 7 Home client connects. Then it gains time at a rate of several seconds per minute. The client connects through a firewall with only the RDP port open. The client runs the same apps on the terminal server that XP clients run with no issues. Using the Microsoft Terminal Server Client application copied to the W7 computer from an XPsp3 computer gives the same results. Current workaround is to sync time every 5 minutes. Any better ideas?
