• Flash alternative for iBook Mac?

  - by Hunter Dolan

  I have a old Apple iBook G4 that I decided to hook up to my main TV. I like the setup because I can surf the internet on my TV now. The only thing that I can't seem to do is watch Flash videos. Apparently Flash Player 10 doesn't play nice with the iBook's graphics card's GPU, leaving all the graphics processing to the CPU which is a disaster. Others suggested downgrading to Flash Player 9, I did that, and youtube worked fine, but Hulu (The main reason I wanted to hook it up to the TV in the first place) did not. Anyone know of a Flash alternative or a Flash 10 fix for the iBook? Or even a Hulu client that doesn't require Flash. Here are my iBook's Specs Model Name: iBook G4 <br> Model Identifier: PowerBook6,5 <br> Processor Name: PowerPC G4 (1.2) <br> Processor Speed: 1.2 GHz <br> Number Of CPUs: 1 <br> L2 Cache (per CPU): 512 KB <br> Memory: 512 MB <br> Bus Speed: 133 MHz <br> Boot ROM Version: 4.8.7f1 <br> Mac OS X Version: 10.5.8 <br> PS: Don't tell me that I need to buy a new computer. I know that I would have better results with a new computer but I don't want to buy a new computer just for Hulu.

• Best option for storage clustering

  - by sam

  I'm working on an application that requires a large amount of storage space and I want to handle storage 'in-house' (Much cheaper than, say, S3) so we will have multiple servers (Initially 4) with large amounts of storage (6TB each). The storage will need to be very flexible and configurable, each piece of data should be replicated on at least 2 servers and must be easily readable/writable from ether an API of a UNIX device/file/folder like a normal drive, I don't mind which. We must also be able to easily offload content to our HTTP CDN (Edgecast), it doesn't need to have built in HTTP support but if it doesn't I'm going to have to write something to get the files onto HTTP so they can be pulled by the CDN. I've looked at a lot of solutions including Eucalyptus Walrus OpenStack Object Storage MogileFS and some others which I can't remember All the servers will be running RHEL 6, they have 4x1.5TB drives which will be RAID1'd into a single partition. All the servers have 1GB/s connections between them and 100MB/s connections to the internet with unlimited bandwidth. They have 2x2.66ghz processors. I understand there isn't a single, perfect answer but it would be nice to get some pointers.

• Windows Media Sharing not 'always' being detected by PS3

  - by Ahmad

  I'm having a weird problem with Windows Media Sharing on Windows 7 .. I have the following hardware in my network: PC 1 --- My main PC --- runs Windows 7 Ultimate x64 PC 2 --- My backup PC --- runs Windows 7 Ultimate x32 PS3 PC 1 is my main PC which has all my data/media on it .. PC 2 is a backup PC I have, but I use it like once in 2 months .. It has nothing installed on it apart from some very very basic software ... Problem is, my PS3 always sees the media sharing service coming from PC 2, but it never sees the media sharing service coming from PC 1 initially .. Both PC 1 and PC 2 have the same media sharing configuration (All everything on all devices on all networks) ... But when I restart both PCs, the PS3 will only detect PC 2's media sharing service, not PC1 .... However here's the twist .. When PC 1 is restarted, and if I view my 'Network' on PC 2, I do see PC 1's Media Sharing Service, and I'm able to play from it too on PC 2 .. To get my PS3 to also see PC 1's media sharing service, I have to do either of the following 2 things: 1) Play something from PC 1's media sharing service on PC 2 ... The PS3 will then magically also detect PC 1's media sharing service .. 2) Go into the Services area on PC 1 and restart the 'Windows Media Player Network Sharing Service' ... After this, the PS3 also instantly starts to see PC 1's media sharing service .. Since my PS3 is like a month old and is properly detecting PC 1's media sharing service, I think the problem is somewhere in the configuration of PC 1's media sharing service ... Also, on PC 1 I have Norton Internet Security 2012 installed, but I've disabled it completely, and have also disabled Windows Firewall (from PC 1 only) .. Can someone shed some light onto this ?

• OSX: Mimic Ubuntu IP Masquerading via iptables with ipfw

  - by Dogbert

  Good day, I am attempting to replicate a setup I have between a router and an Ubuntu PC, and have the same setup working on my MacBook (10.6, Snow Leopard). First, I have a router that has a USB port. When I plug it into my Ubuntu PC, it creates an RNDIS connection, allowing me to connect to the router over the USB cable via an IP connection. When I plug it into my computer via USB, it gets assigned an IP address of 172.16.84.1, and a new adapter appears when I type ifconfig. I can then SSH into the device via ssh [email protected]. When I log in to the device, I flush the routes, then create the default route: admin@localhost> route -f admin@localhost> route add default 172.16.84.2 Now, in my Ubuntu machine, I use iptables to enable IP masquerading: root@Valhalla> sudo iptables -t nat -A POSTROUTING -s 172.16.84.2 -j MASQUERADE Once this is all done, the router has internet access over the USB connection to my PC. I am trying to replicate this exact setup on my MacBook now (Snow Leopard), but iptables does not exist for OSX, not even a Macports version exists. I have scoured through other questions on StackOverflow that cover the usage of the ipfw command, which apparently works as a drop-in replacement for iptables. However, the syntax is significantly different, and I'm pretty much lost. Does anyone with some experience with ipfw have some suggestions on how I could accomplish this and create a NAT connection via IP masquerading like I could with my Ubuntu PC? Thank you for your assistance.

• virtualbox snapshot size

  - by intuited

  I've started using Windows 7 under VirtualBox on an Ubuntu 10.10 host. I took about 6 snapshots over the course of setting up the VM from the Windows restore image that came with the computer. My installations were more or less limited to windows updates, antivirus, and the VB Guest Additions. I uninstalled much more than I installed. The VM was running for about 24 hours total. The snapshots increased in size at a worrisome rate, even when the machine was idle: the snapshot .vdi file for the period between 11:22 PM and 9:02 AM is 6 gigs in size; during that time very little happened. The other .vdi files are between 0.5 and 3 GB, most between 1 and 2 GB. The corresponding .sav files are between 0.5 and 1 GB. The Internet connection where I was doing this is limited to 30KB/s download, which, constantly saturated, works out to less than 3 GB per 24 hour period. Is this normal? Is there something that can be done to make snapshots more practical? update On starting up the VM again, I've noticed that mscorsvw is using significant processing time. Apparently this process [precompiles .NET assemblies]. This may have been going on during the period when I was taking snapshots, which might explain some of the snapshot size increase. I would be somewhat surprised to learn that this could be responsible for over 10 GB of additional disk usage, or that it would run for roughly 24 hours. Is this possible?

• Most transparent way to connect two LANS using a WET610N Wireless Bridge

  - by Spencer Ruport

  I have two wired systems hooked to a Linksys WRT54GL wired/wireless router which is also hooked to my internet. I'll refer to this as LAN1. I have two more systems in another room that are connected wirelessly. Recently I decided I would much rather have another wired LAN in the other room and use a bridge to connect them. This would be LAN2. Prior to hooking up the device I assumed that the ethernet side of the bridge would have a DHCP server so that I could simply hook it up to a switch and I'd be on my way. However that isn't the case which leads me to believe I'll have to add one to LAN2 correct? Or is there some way to have the DHCP from LAN1 also hand out IP addresses to LAN2? If I do need a DHCP device on LAN2 what would be best? Another hardware device or should I just install some DHCP software on one of the systems (since they're both on 24/7 anyway). Any recommendations would be appreciated. :)

• iRedMail home setup - use different SMTP relay for different destination domains

  - by John

  Hello helpful server folks, I'm messing with iRedMail. I've mostly been successful, I think I have an SMTP problem. I have changed RoundCube (webmail) to use BrightHouse's, my ISP's, SMTP server for outgoing. It works fine, I click send and poof, I have gmail. I can reply from gmail to my email server, and it works. It took 10 hours for the email to show up, which is a different problem, I think, but it does work. But when I send from my server TO my own server, my ISP's Postmaster account sends me a cryptic blurb. I just got off the phone with them, and they say it "should work", and that they can't reach my pop3 server. (pop3, pop3s, imap, and imaps are all open on my router and forwarded to the server, I'm not sure what I need, I'm just covering my bases...) pop3 and/or imap as external interfaces are just formalities, I really just want webmail to work. Roundcube only takes one SMTP server in its configs. How can I configure Postfix to relay / forward emails to my ISP's SMTP, while taking messages bound for my own domain and processing them? Since my ISP won't let me "bounce" my emails off of it. Maybe I'm vastly misunderstanding how e-mail works in general: To receive mail, I should only need port 25, SMTP, open to the internet, correct? Should I be concerned about some authentication failure from the outside to my relay? (My relay requires user/pass to use, my ISP's requires none.)

• What do "Unknown SSAP" and "Unknown DSAP" mean in tcpdump?

• Network Traffic Log

  - by Chris Becke

  Background - On my "home" network I have a Linksys WTR45GL router providing my internet access as well as a wireless AP. Connected I have * 2 Windows PCs (wired) * At least one laptop (Wired) * Some 802.11 enabled handheld consoles (PSPs) * A Nintendo Wii * Some windows XP pcs used by the people in the granny flat. Where I live, South Africa, well, 1Gb worth of monthly cap is, while not expensive, costly enough that I'd like to be sure that all the bandwidth used by devices on my network is ... well ... legitimate and not the result of neighbors parasiting my wireless, malware or just the result of "liberal" download policies in my software. I got the Linksys WRT45GL on the understanding that there were custom firmwares (DD-WRT and Tomato) that allowed bandwidth tracking, but there doesn't seem to be any facility to get a log of traffic that can be examined to see (a) which local devices were the biggest consumers of bandwidth and (b) what they were connected to. What tools are there for logging traffic such that, when it gets to that OMG moment in the month when all my bandwidth is gone, I have a chance to find out what the hell used it all up (and hopefully attempt some corrective action).

• How to fix Browser Blue Screen of Death?

  - by WilliamKF

  I am running Windows XP SP3 and Firefox v3.6.2 and Internet Explorer and have an issue with Firefox and IE causing the Blue Screen of Death. If I run in Windows safe mode, it does not occur, but running normally, it seems my firefox profile is going bad and results in certain web pages causing the BSOD. IE is also getting BSOD on some pages. For example, presently, if I visit ebay.com in Firefox, it gets BSOD. It also fails when visiting http://www.google.com/ig?hl=en&source=iglk. IT removed my Firefox profile and that seemed to fix the issue for a while. However, now it has started occurring again. I turned off all firefox extensions and it still occurs. I'd like to fix my system so this does not occur. The IT folks don't seem to be able to solve this, so I am trying to fix it on my own. The BSOD is about something like (from memory) DRIVER_IRQL_NOT_LESS_OR_EQUAL. Why would safe mode avoid the issue and what does that tell us about the probable cause? I don't want to have to keep deleting my profile, so I'd like to find out the cause of the corruption.

• RRAS VPN on windows 2k3 AD, can access rras server only.

  - by nopsax

  I'm setting up a test lab and here is the current configuration: 192.168.86.201 - a windows 2003 machine acting as PDC with AD/DNS/DHCP/WINS. 192.168.86.62 - windows 2003 machine is the RRAS server with IAS, also a file/print server. 192.168.86.6 - gateway/router to internet 192.168.86.21 - Windows XP Workstation Everything works on the internal network, File/Print/AD etc. Whenever a user connects via vpn to the RRAS server remotely using their domain credentials, they are assigned an ip address from the 192.168.86.201 machine along with the wins server address etc. The vpn user can then ping/access resources on the RRAS server, but cannot ping/access resources of any other machines by name or ip. However, if I ping by name, it does resolve to the correct ip address, just no replies. I did notice that on the RRAS server the 'internal' interface gets an ip address of 192.168.86.75 when a remote user connects, and the remote user is assigned, for example 192.168.86.71 . The RRAS server responds on both the .62 and .75 ip addresses. The client also unchecks the 'use remote default gateway option'. Also, I tried connecting a laptop to the physical network, joining the domain, then going remote and dialing the connection before domain login, and everything seems to work, e.g. browse-able shares via network neighborhood. But I can't really join the domain remotely if I cannot access any other resources. I really need to monitor traffic to see whats happening to those packets but won't be able to until this weekend. Any help is appreciated, will provide whatever configurations are needed.

• Are Colocation Cross Connects Worth While

  - by SvrGuy

  We currently operate three clusters of collocated machines in different data centers. Recently, I became aware that our newest data center will offer to cross connect us to a bandwidth provider free of charge. In the past, I never really investigated a cross connect for bandwidth because I figured that the rates would be similar to what we are paying the colo now and that it would reduce our resiliency (because we would only be using one or two carriers for IP, where as the colo uses, say 8 different providers). Then I saw an ad for hurricane electric internet services (http://he.net/cgi-bin/ip_transit_quote) that gave a price for IP transit at $1/Mbs, which is much better than the $30/Mb we pay for the blended bandwidth. What are people out there typically paying for bandwith via cross connect and how hard is to setup? Is my understanding that what you do is open agreemetns with two or three ISPs, cross connect to them and then configure your top of rack router on their network. Can you really get IP transit down to a couple of dollars per megabit per month just by doing the routing yourself? Or, is my understanding of cross connection fundamentally wrong?

• Can't pop3 from exchange server after a reboot

  - by BLAKE

  Last night I shutdown my Exchange 2003 Virtual Machine, I added a new VHD (For backups), and booted it again. Now I can't POP3 email from it with Outlook 2007. In Outlook I get the error: Task '[email protected] - Receiving' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP).' Does anybody know what is wrong? All I did was a reboot. I haven't formated the added disk. There are no weird errors in the event log. I can still send mail with Outlook over port 25. I can send and recieve mail with OWA. I can POP3 the mail to my phone (it take about 15 minutes after sending a message, but I do get it eventually). EDIT: The 'Microsoft Exchange POP3' Service says that it is started but if I stop it and try to start it again, it fails saying 'Could not start the Microsoft Exchange POP3 service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion.' I did some googling and someone on exchangefreaks.com said that if I use task manager to 'End Task' on inetinfo.exe, then I can start the POP3 service fine. Does anyone know what causes this problem? I am fine for now since I did get the Service started, but If it does this after every reboot...

• Pentium 4 Willamette vs. Faster Celeron Northwood [closed]

  - by Synetech inc.

  Which is the preferable of the following two processors? Intel® Pentium® 4 Processor 1.70 GHz, 256K Cache, 400 MHz FSB Willamette Intel® Celeron® Processor 2.40 GHz, 128K Cache, 400 MHz FSB Northwood Details: A few months ago my motherboard died, so I bought a used computer that had a 2.4GHz Celeron. My old system had a 1.7GHz Pentium 4, so now I’m trying to decide which CPU to use. Obviously a P4 is preferable over a Celeron, but the Celeron is (significantly?) faster than the P4. I’m wondering if the faster Celeron might be better for certain tasks (ie, stronger but dumber is better at some things than smarter but weaker). I tried Googling for some reviews and comparisons for graphs to get a clear depiction of which is better overall, but found nothing that helped. (I did manage to find one page that indicates (apparently by poll, not benchmark) that the Celeron is better.) So which CPU should I use? Does anyone know of some graphs that I can use to compare the two? The system is a general-purpose machine for word-processing, Internet, and casual games (not Crysis, but not Solitaire either). It will be running Windows XP. The board is a 478 with 400MHz FSB.

• Weird connectivity issue wtih USB Wifi stick.

  - by Carlos Nunez

  Hi, all! I'm not sure if this is the appropriate place to throw this question out there, but I'll give it a shot. I'm setting up two PCs, and I've been having massive troubles getting a USB wireless dongle working. I have two Sony VAIOs (Windows XP, SP2) that I found second-hand, and since they will be in a location too far to connect by Ethernet (no, can't do patch panels here :p), I need to connect them by wireless. Easiest and cheapest way to do that at the moment is by using two USB wireless sticks that I've had for a while, but never used. One of the computers is using a SMC-manufactured card, whereas the other is using a Belkin F5D7050. The box with the SMC card can see and authenticate with my router just fine, and has no problem obtaining a DHCP lease. The box with the Belkin, on the other hand, isn't so lucky. While it can see my router and associate with it, it will not obtain a DHCP-issued address. Worse, when I assign a static IP address to the NIC, it can ping the entire network and access the internet (meaning it can authenticate with the router), but no computer can ping to it UNLESS that computer pinged the computer that's pinging it first. Confused? Well, so am I. Has anyone had this issue before? Is this just a sign of a bad card? (For the moment, I have it connected by Ethernet, as I haven't moved it yet. However, this will be a problem when I set it up in its new home later.) Thanks! -Carlos Nunez

• Ubuntu 10.04 Keyboard and Mouse Freezing Problem

  - by nitbuntu

  I had a partition setup with Windows XP and Ubuntu 8.04 dual booting. I recently upgraded to Ubuntu 10.04 by installing fresh from CD but leaving the previous /home folder as is. Things seemed to be working fine, but started finding that my mouse and keyboard were freezing. After a quick search on the internet, I found the following suggestions as shown here:- Ubuntu Forums Here the suggestion was to:- Edit /etc/default/grub, go to the line that begins like: GRUB_CMDLINE_LINUX_DEFAULT= Change it to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=off" After that, run this command: sudo update-grub and Reboot This seemed to have resolved the issue but after a couple of days I again find my mouse and keyboard freezing. I also find that my parallel port printer had also stopped working. I have saved the output of dmesg and my syslog. The first can be viewed here but the syslog had too many characters, so if someone can suggest an alternative to freetexthost, I can post it there. Moreover, if there is any other information that should be provided, do let me know. I do hope we can get to the bottom of this issue. Thank you in advance for any help that could be provided.

• samba4 dc "network location cannot be reached"

  - by mitchell babies peters

  to clear the air centos 6.4? (maybe 6.3) as the server, running samba 4.0.10, trying to add a windows 7 client that has connectivity to the server. this is what windows shouts as me as it mocks my dependence on network infrastructure. "the network location cannot be reached." i have access to the domain contoller (dc) im using the dc as the domain name server (dns) already, and the name is correctly resolving, and it is correctly forwarding outbound traffic. i have nothing but self taught experience with active directory(ad) so if i am missing something obvious, please shout it out, but keep the verbal abuse to a minimum. i checked samba4DC + my error and found nothing relevant to my issue, if i missed something please point me in that direction. the weekend is just starting as i write this so i probably wont be back on to check this post for a day or three, but i might because this mystery is killing me. i followed the samba4 as a dc guide here and i supplimented gaps with this i have tested kerberos, ntp, and set my DC as the clock to sync to in my windows client and it appears to be a very small fraction of a second off so that shouldn't be it. also, firewall and selinux are both off for testing. i have also tried disabling ipv6, and cleared the registry of ipv6 records (allegedly the default samba4 as a DC runs as windows server 2003 which allegedly does not support or tolerate the existence of ipv6, fair warning, i heard this on the internet so it is probably a lie) i have tried a few other things that i have forgotten because i have been doing this for a day and a half now. ideas welcome. suggestions for alternatives are also welcome, as long as they are free. i was given a budget of $0 dollars and told to implement active directory (no prior knowledge of active directory at that point).

• running red5 on port 80

  - by ArneLovius

  I have a red5 application http://code.google.com/p/openmeetings that runs under red5, and is accessible on port 5080 and 8443 I've installed it on Ubuntu 10.04 The eventual aim is to have it accessible via https on 443 instead of 8443, but I thought I would initially try on 80 so that any issues were just down to the port configuration and not SSL certificates. I've tried changing the port from 5080 to 80 in the red5.properties file, but it fails to start. In the red5.log I have seen ERROR o.a.coyote.http11.Http11Protocol - Error initializing endpoint java.net.BindException: Permission denied /0.0.0.0:80 In the error.log I have seen ERROR o.a.coyote.http11.Http11Protocol - Error initializing endpoint java.net.BindException: Permission denied /0.0.0.0:80 and ERROR org.red5.server.tomcat.TomcatLoader - Error loading tomcat, unable to bind connector. You may not have permission to use the selected port org.apache.catalina.LifecycleException: Protocol handler initialization failed: java.net.BindException: Permission denied /0.0.0.0:80 There is nothing else installed or running on port 80, so I presume that this is a "needs to be root" situation. I would rather not run an Internet accessible web service as root. I know that Tomcat can run on port 80 by changing “#AUTHBIND=no” to “AUTHBIND=yes” in /etc/default/tomcat6 but I have not been able to find anything similar for red5. Am I on a hiding to nothing, or is there better way than running as root ? Thanks!

• Task Manager Does Not Start Every Time

  - by diek

  I have had a problem that started some time ago, 6 months maybe. I should have noted the first instance but I didn't. I am using Windows 7 Pro, 32bit. Under normal circumstances I can open up the the Task Manager, via the task bar or cntrl alt del. When I get a program stuck, causing a freeze or non-responsive system I try to open the task manager. It will not work. I have had plenty of similar problems in the past and I had no trouble getting it open. I have searched the internet but the only results I can find are when the task manager will not start under any situation. I am running ESET NOD32 as the anti-virus. The latest example happened when I opened a new tab in Google and tried to copy an image. Google accounts for at least 50% of the examples. Ran System File Checker tool, sfc /scannow as recommended on another post. No errors returned. Any guidance would be appreciated.

• Windows 3 Animated Background/Desktop/Wallpaper

  - by Synetech

  In the summer of 1995, I visited some family in Los Angeles. My uncle had a computer with Windows 3 (or some version thereof since Windows 95 had not been released yet). In Windows 3, there was no desktop or wallpaper like in later versions; instead you could set it to a simple pattern (still possible in later versions before XP) like hounds-tooth or bricks (interestingly, there seems to be next to nothing available on the Internet about this anymore; no screenshots and almost no pages). I recall being amused when I found a program (on the still young “world-wide web”) that would actually let you set an animated background. It was smooth and fluid and was quite an amazing thing at the time. If I recall correctly, it had several built-in animations including one of a light-orange-pink background over which storks flew towards the top-left, possibly with some light stuff floating in the “background” (they were actually animated and flapped their wings, not simply translated coordinates). The storks were somewhat simplified, black-line drawings. Over the years, I’ve tried finding it again a few times but never could. Worse, it’s become harder and harder over time as new programs came out and polluted the search results. I’m hoping that someone remembers this software and knows some useful information like the author or where to download it. (No, it’s not ScreenPaper. That was created in 1997 to let you set a screensaver as the Windows 95/NT4 background. This was at least two years earlier for Windows 3 and I’m almost certain it had these animations built-in—I don’t recall any stork screensavers for Windows 3.)
