• I think my laptop just died

  - by Joel Coehoorn

  I have a Dell 1330M that as of about 15 minutes ago will no longer POST. What happened was I was working, stepped away for a moment, and when I came back it was turned off. I thought that was odd, but turned it on and things seemed fine. About 1/2 hour later it crashed and restarted, but came up fine again. It did this once more. At this point I was starting to get worried, but I hadn't had any problems with the laptop before and every crash was after doing some work in a virtual machine that I don't often use, so I at put the blame there. It didn't feel like it was overheating anywhere and there's no ozone smell of overheated electronics. Then it crashed a final time and now when I turn it on all I see is a bright screen with a bunch of vertical lines (noise). I've tried removing the memory sticks one at a time, but I get the same result with either memory stick in either slot. With no memory at all it stops earlier in the POST process and the screen is completely blank (black, no backlight). As I type this, I hear a double beep from the system about once every 10 minutes. I'm pretty sure the hard drive is fine because it fails during post, before anything off the drive is needed. The power supply seems good because the screen is nice and bright. It's not the RAM because swapping that around made no difference. The leaves motherboard (which I doubt and can replace) and CPU (which just might be changable). Any ideas? Is there any hope for this laptop? I'm rather fond of it and I'd have a hard time replacing it with anything near as nice.

• Random “Lost connection to MySQL server at 'reading initial communication packet', system error: 0”

  - by user1606545

  Sometimes I get the error from MYSQL server: Lost connection to MySQL server at 'reading initial communication packet', system error: 0 I cannot find the cause, since most of the time it works, but every week for some hours I get this error. I googled, but there seem to be only users which have this error permanently. But in this case, it only occurs sometimes. I checked hosts.allow and hosts.deny, but the host is allowed and not denied. Also sometimes I get the error: File './database/table.MYD' not found (Errcode: 24) It occurs very rarely. But it occurs for some hours once a week, sometimes on multiple days, but suddenly the problem disappears again. I have checked the open files limit. It's 2048 and should be absolutely enough. I also tried to increase the number of open files nevertheless, but no effect. I thought, perhaps the process does not close some tables. But this is impossible, because after a while everythings o.k. again and the process opens maximum 100 tables at once. I also checked the MySQL-runtime-environment, and there were 930 opened files. I cannot explain that. After a while it's 129. I am running a MySQL-Server on a SUSE-Linux machine. I connect to the MySQL-Server from another host by the command line tool "mysql" and by MySQL-C-connector. The MySQL-Server is version 5.0.67.

• Primary/secondary ethernet interfaces in Ubuntu 9.10

  - by Josh

  I have an Ubuntu 9.10 machine with three ethernet interfaces, eth0, eth1 and eth2. eth2 is connected to a private network. eth0 and eth2 are connected to two different LANs. Either one will provide access to the internet. All three networks have DHCP servers. Using Ubuntu's the default settings (And Gnome), when I boot up all the interfaces are active and my system gets three IP addresses. However any attempt to access the internet results in connection timeouts and other weirdness. I suspect that traffic is going out on one NIC (like eth0) and coming back in on another (like eth1). I'm not sure what's going on. The only way I can access the internet at the moment is to bring two of the devices down with ifdown. How can I configure eth0 as my primary interface so all trafic goes out by default on that interface, while keeping the other two active? Also, I want to make sure Avahi broadcasts properly on all three IPs so that the computers on the LAN of eth1 can still connect to myHostname.local...

• IIS 7 much slower than IIS 6

  - by JoeJoe

  I have a asp.net 3.5 web application running fine on Windows2003 IIS6. I published same exact application to IIS7.5 (Win2008R2) on a faster box (i5,8Gram) and it is significantly slower. 5-6 sec per page vs. 1-2 sec per page. During that time the Task Mgr CPU is always under 10%. Both attach to same database on other box. Benchmark is consistent from any other client browser or machine. I have connection pool on both, compression on both. Same network subnet. Forms authentication (no SSL yet). Can you give me steps on how to troubleshoot where the delays are being inserted or settings in IIS7 that I may have overlooked. Just using defaults. There is only 1 web site on each box. I understand the roles of an Application as defined in IIS has changed. There is no special Application defined in IIS.

• What Device/System to use as a "router on a stick"

  - by Jeff Leyser

  I need to create several distinct VLANs, and provide a way for traffic to move between them. A "router on a stick" approach seems ideal: Internet | Router with Trunking Capability ("router on a stick") * * Trunk between router and switch * Switch with Trunking Capability | | | | | | | | | | | LAN 2 | LAN 4 | | 10.0.2.0/24 | 10.0.4.0/24 | | | | LAN 1 LAN 3 LAN 5 10.0.1.0/24 10.0.3.0/24 10.0.5.0/24 We have trunk-capable Layer-2 switches. The question is what to use as the router on a stick. My choices seem to be: 1) Use an existing Cisco 5505 ASA firewall. It appears the ASA can do the routing, but it's a 100Mbps device, and so seems sub-optimal at best 2) Buy a router. This seems overkill. 3) Buy a Layer-3 switch. Also seems overkill. 4) Use an existing Linux Box as a router 5) Use a new Linux box as a router' 6) Something I'm not thinking of I think either (4) or (5) is my best option, but I'm not sure how to choose between them. I expect the amount of traffic that has to cross the VLANs to be somewhat small, but bursty. How much load does routing add to a CentOS machine?

• email attachments [closed]

  - by Alan Doolan

  My company currently use software on a local machine that will take an email from the email server, extract the attachment, rename it and then add it to a folder on a webserver using ftp. This works well but they are currently asking if it can be done 'in the cloud' or what they really mean, not local. Is there any thing that would do this on the server itself? I should clarify a bit. The attachements are various reports that are being sent to different email addresses (mostly google corporate and free accounts). We need the reports to be on a folder on a webserver so that internal pages can take the information in the reports (csv) and use it on the webpages or adds them to a separate database. The key part being that the files need to be in the particular folders. Though it does work to have a computer running software that will take the files, renames them to the required name and uploads them to the folder it relies too heavily on one computer working all the time. This is not something we can depend on at this point. I'll be honest, I'm a web developer and not strong with server systems past my particular standard requirements so this is beyond me. though yes, I am aware that my boss is not 100% sure what 'cloud' means but likes the word.

• Exchange 2003: Accounts with only OWA access unable to change passwords when expired or forced

  - by radioactive21

  We have accounts whith only OWA access, because they are generic accounts and we do not want the accounts to be used as machine logins. We have a password policy that users must change their passwords every 6 months. The problem we are having is that since the accounts are not loging into the machines, when the password policy kicks in it is preventing users with OWA only access from changing their password. Also, when we select "User must change the password at next logon" it also causes the same issue. We have two exchange servers the main one and a front end one. what we have been doing with these generic account is in properties, under the "account" tab we restricted "log on to" to the front end server. Just to clarify, when we have no restrictions, users can change their passwords via the web without any issues. It is only when we force them to only login via OWA that they cant change passwords. I tried adding our domain controler and main exchange server to the "This user can log on to The following computers" in the account tab, but still it is not allowing them to change passwords. Currently I have to manually reset the passwords for OWA only accounts. Is there anyway to allow OWA acconts to change passwords? EDIT: Users restricted to only OWA can change their password via the web browser without any issues when there are no restrictions. In other words normally they can just log into outlook via the web and change their password, but when the password policy expires or we force them to change their password at next login, they are unable to.

• Blue screen of Death on Install

  - by Toby Allen

  I have a machine with Windows Vista Installed. It has an Intel X25 SSD as the System Drive I want to reinstall (I plan to format and overwrite Vista) with XP. When I boot up using the Dell XP CD it loads the initial drivers then i get a Blue Screen. This is quite concerning. The installed OS works ok, but its giving problems so I want to remove it. Should I just format the SSD and try again? Will this make any difference? Can I do something to avoid hitting the Blue Screen? Its possible I had corrupt sectors on one of the other disks, will a new XP install use the System drive or drive 0? Can I force the install to use a specific drive when installing? Error: *** STOP: 0x0000007B (0xF78D2524,0x0000034,0x00000000,0x00000000) I never did find the answer, however I removed the SSD and tried to install on other disk - CRASH I disconnected the other disk and tried to install with only SSD plugged in - CRASH I removed 1 block of RAM - CRASH I used a windows 7 CD - NO CRASH

• WIN7 constant BSOD 0x7B on boot, not producing any dump files where to go from here?

  - by prayingpantis

  So my one win 7 pc has been getting a BSOD on boot (roughly a sec after load screen starts) after a power failure. The complete stop code is 0x0000007B (0x80786B58, 0xC0000034,0x00000000,0x00000000) I've searched for quite a while now on the net and it seems like most people gave up after gettting 0x7B and no dump files. What I've tried so far: startup repair - reports it cannot repair computer automatically. BadPatch is reported somewhere in a problem signature contained in the problem details. startup repair with a WIN 7 CD - also fails, I can't recall what the error was, but it was not the same as the error produced with the start up tool shipped with the version of WIN 7 installed on my machine (I think the text had something ACL-ish contained in it) used a boot disk (Hiren's boot iso) - I used it to enable the CrashDump registry key and then after BSOD, read the HDD's dump locations but it was empty. Note, I'm quite sure the registry keys I edited are the correct ones, since the reboot on BSOD option was enabled by default and after I changed the regkey controlling this functionalitty to 0 the BSOD stayed after I booted again. check disk - works and returns no problems, also it seems I'm able to access all my files on the HDD. mem test - works and returns no errors So I'm not sure what else I can do to figure out what is the problem here. I read somewhere that you can use WINDBG to remote debug another PC, but I'm not sure if this is possible since the OS isn't even loaded yet? Also the last driver change I made on the system was installing a video driver, but I had no problems with it and were able to reboot several times until the power outage happened and the BSOD appeared. Any help or guidance for a way to DEBUG this problem would really be appreciated (I'm not really that keen to try a whole bunch of random fixes, I'd rather try and narrow down the problem first).

• Windows Server 2008 IIS7 - page requests randomly hang or timeout

  - by seb835

  I've just installed a fresh copy of Windows Server 2008 x64 with IIS7 and PHP (fast CGI). However, I'm noticing that after moving my web site from a similarly specified machine to this one, I'm getting issues. The issue seems to be that randomly, as I'm clicking through the web pages being served, the browser will suddenly hang saying "waiting for mysite.com...". Sometimes the page will then timeout, or finally resolve after 20 to 30 seconds, but maybe missing the CSS style sheet. Very strange, as this is the only website installed on this new server, and only myself using/testing it. Server is installed in the same data centre below the old server. Has anyone else had a similar problem? I tried increasing the max workers pool to 10 (from 1), but this has no effect. Seems to happen most frequently after 1 or 2 minutes of inactivity on the website, then trying to load/refresh a web page. Many thank for any info and help. Kind Regards, Seb

• Remote offscreen rendering

  - by redmoskito

  My research lab recently added a server that has a beefy NVIDIA graphics card, which we would like to use to do scientific computations. Since it isn't a workstation, we'll have to run our jobs remotely, over an ssh connection. Most of our applications require doing opengl rendering to an offscreen buffer, then doing image analysis on the result in CUDA. My initial investigation suggests that X11 forwarding is a bad idea, because opengl rendering will occur on the client machine (or rather the X11 server--what a confusing naming convention!) and will suffer network bottlenecks when sending our massive textures. We will never need to display the output, so it seems like X11 forwarding shouldn't be necessary, but Opengl needs the $DISPLAY to be set to something valid or our applications won't run. I'm sure render farms exist that do this, but how is it accomplished? I think this is probably a simple X11 configuration issue, but I'm too unfamiliar with it to know where to start. We're running Ubuntu server 10.04, with no gdm, gnome, etc installed. However, xserver-xorg package is installed.

• Website hosted on my virtualbox web server not displaying images or applying css when viewed through phone

  - by WebweaverD

  I would really appreciate it if someone could help me. Please let me know if you need more info in the comments. My Set Up I have a windows 7 pc. On it I run a virtual box VM with a ubuntu 12 guest os and LAMP setup. I share files between the two machines using samba from linux to windows and using windows file sharing (Workgroup) the other way round. The vm is set up with a bridged network adapter and can happily serve web pages to my host machine. I use DHCP reservations on my home wireless router/modem to reserve an ip for the vm and give it a sitename.dev in my windows host file so I can access it at sitename.dev through the browser. The Problem So far so good but I have a dev project which needs a lot of mobile template development, now obviously I can use a browser plugin to simulate a mobile device but I would like to be able to see the real thing easily on my phone during development. So ideally I would like a similar setup on my iphone to my windows setup Now I'm not great on networking and dont have much experience with web server set up. So when I typed the ip of my virtual box into my iphone i wasnt expecting to see anything. I was pleasantly surprised when my site loaded up. The javascript even seems to be running but the images and css are not happening. My Question 1) What is happening here, is it something to do with the bridged set up on the vm network? 2)How do I make the sites load properly through my phone Notes I've also tried another phone. The same sites viewed on live servers work fine.

• No outbound internet connection after restarting CentOS 6.3

  - by wnstnsmth

  After restarting a headless CentOS 6.3 machine, it lost outbound internet connectivity, i.e. I can still connect to the server via SSH (ssh root@**.126.18.56), but stuff such as ping google.com gives google.com: unknown host, and yum list some_package gives a lot of network errors. This is what ifconfig gives: eth0 Link encap:Ethernet HWaddr 00:25:90:78:2D:5D inet addr:**.126.18.56 Bcast:**.126.18.255 Mask:255.255.255.0 inet6 addr: fe80::225:90ff:fe78:2d5d/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:75594 errors:0 dropped:0 overruns:0 frame:0 TX packets:787 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7074741 (6.7 MiB) TX bytes:144391 (141.0 KiB) Interrupt:20 Memory:f7a00000-f7a20000 eth1 Link encap:Ethernet HWaddr 00:25:90:78:2D:5C UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b) Interrupt:16 Memory:f7900000-f7920000 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:6 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:504 (504.0 b) TX bytes:504 (504.0 b) I have absolutely no clue how to debug this, and I find it very strange since I can still connect via ssh. EDIT: Weirdly, /etc/resolv.conf does not contain any entries, or none that I can make sense of: # Generated by NetworkManager search sui-inter.net # No nameservers found; try putting DNS servers into your # ifcfg files in /etc/sysconfig/network-scripts like so: # # DNS1=xxx.xxx.xxx.xxx # DNS2=xxx.xxx.xxx.xxx # DOMAIN=lab.foo.com bar.foo.com So is it possible that rebooting the server erased that file? It worked before at least! And how do I solve this? By the way, pinging an IP address works.

• Can't access certain web sites - reset router, any ideas?

  - by IniTech

  EDIT: This problem was resolved by my ISP - had to do with damaged fiber in one of their locations. Thanks to everyone that helped. Not sure if this is the right site (I'm a StackOverflow user) so I thought I'd give it a shot. I'm having trouble connecting to certain sites on any of the 3 machines that are on my LAN. The following sites are returning "Problem Loading Page - The connection has timed out" Sourceforge.net CNet.com Microsoft.com OpenDNS.com even my company's webiste I was worried about possible malware/virus, but I don't think that is the case (given the inability to access my company's site and the fact that all 3 machines are having the same issues.) I've tried with IE8, FF, and Chrome I have reset my router (WRT54G) and my machine(s) multiple times. EDIT: It is also worth noting that this page spins constantly and no avatars show up (I'm assuming it is trying to access gravatar.com with no success.) EDIT: I have the same issues directly connected to the modem. So, any router config is probably not the issue I'm a programmer, not a network guy - any ideas?

• Thunderbird 15.0.1 cannot use Exchange 2003 SMTP

  - by speedreeder

  I'm having the strangest time getting a Thunderbird email client to connect to my Exchange 2003 server. I got the incoming IMAP account set up no problem, and I can receive mail. However sending mail will not work no matter what SMTP settings I enter. After checking the server, the proper settings should be port 25 with no authentication or connection security, which I have entered. I can ping the hostname of the server from the client machine in question. The Thunderbird error message I get is: "Sending of message failed. The message could not be sent because the connection to SMTP server -hostname omitted- was lost in the middle of the transaction." So I went to the server and double checked the settings for Exchange's SMTP stuff. I have it correct. I tried to telnet (on the server) to localhost 25. It appears to connect and then disconnect immediately, no message, no nothing. When I telnet to other ports (POP-110 for example) I get proper connection messages and a stable connection. There are no firewalls on either the client or the server. There's a firewall on the network but LAN-LAN traffic is unrestricted. I can reproduce the Thunderbird error on a second client, and I can't get any client to be able to telnet in. Anyone have any ideas?

• Can't access YouTube

  I can not seem to connect to YouTube at all. If I connect directly to YouTube (youtube.com) I get this: And if I try to connect via video directly (youtube.com/watch?v=), I get this: Here's how this isn't a web issue: I have malware on my computer I believe. And the question here is, how do I get rid of it, or what possible issue could this be? I can verify this is not a website issue or wifi issue, I've tried to connect on another computer in my wifi, and it worked. It is the local machine issue. I've tried to get rid of malware at my best and also have tried to disable possible virus extensions. All can out as the same result: no help. Also, I am unable to find these hiding viruses. I used malware-bytes and Microsoft Security Essentials. Edit: This is OBVIOUSLY Windows.

• USB drive was bootable, but no longer boots

  - by i-g

  I'm trying to install a new OS onto a computer from a bootable USB stick. I previously installed Ubuntu Linux and it was a piece of cake -- I downloaded the ISO image, used UNetbootin to copy it to the USB drive and make it bootable, and that was that. Now, however, no matter what I try, I can't make the same USB drive bootable again! I've tried formatting it as FAT32 and NTFS. I've tried several different Linux distributions and Windows 7. I've tried using UNetbootin, Windows 7 USB Download Tool, WinToFlash, and manually making it bootable with diskpart/bootsect/bootrec. (Yes, I've tried bootsect /nt60 x: /force.) None of this seems to be working! When I try to boot from the drive, the machine reads from it (I can see the drive's LED blinking) and then gives me the same "Insert system disk and press Enter" message. (I've disabled booting from the hard drive.) Am I missing something I need to do to make the USB drive bootable again? I think it lost some pixie dust when I formatted it with the standard Windows formatting tool (it was quicker than deleting files), but I have no idea what it was or how to get it back. The USB drive in question is a SanDisk Cruzer 8GB SDCZ6. The computer I'm working on is running Windows Vista SP1.

• Are there any other causes of this error that are NOT related to initial setup?

  - by LordScree

  I'm trying to diagnose an issue at a customer site. They are receiving the following error: A network-related or instance-specific error occurred while establishing a connection to SQL Server I've seen this a few times, but only during the initial setup - it's often caused by one of the following: The database server is turned off The network connection between the database server and the application is closed or somehow blocked (e.g. a firewall) The SQL Server instance is not set up to receive remote connections from the application server (e.g. TCP is turned off, remote connections are disabled, or the "SQL Server Browser" service is stopped/disabled) However, if I assume that no configuration changes have been made, I'm trying to postulate on what the reason might be for getting this error at a random point after the initial setup. My initial thought is: SQL Server machine has run out of resources (e.g. RAM) and is unable to accept new requests from the application server Is this a valid theory? What other possible causes are there of this error that are not related to the initial setup of the server / application connection? Or is it simply impossible that this error could occur without a configuration change having been made (either on the SQL Server side, application side, or somewhere in-between (network))? NOTE: I believe this question differs from the plethora of questions related to this error message because the application and server have been talking to each other quite happily until now (most, if not all, other questions seem to relate to initial setup).

• exchange server 2010 with multiple domains

  - by air

  i have one exchange server 2010, which is working fine with one domain. my exchange is working as follows pop3 collector collect emails from one master catchall account and then deliver to exchange server, this working perfect. now what i want to add another domain to same exchange, i have added new domain as trusted domain & email policy and this new domain email account works fine with internal emails. now what i have done, i again forward new email account to same catchall account. but if i send email from any other external email address email is bounce, i can see email receive by pop3 collector but bounce by exchange server. to make you more clear let me explain logic on which i am working. i have 2 domains 1. domain1.com ([email protected]) 2. domain2.com ([email protected] -->[email protected]) now on my machine with exchange server i have pop3 collector which collect all emails from [email protected] and forward to exchange 2010 server. all emails to domain1.com is working perfect but when i send email to [email protected] this email redirect to [email protected] perfectly but when exchanger server receive this email, it bounce. i have also study the url link text and follow the whole process but no success. i also check that my DNS/MX is working fine as the bounce message is going from my exchange server. EDIT the only problem is with accepted domain, as email come to exchange server then bounce back. i just try this today i create one user called test, then i goto his properties -- email there was only one email account [email protected] i try to send email to [email protected] from internet (email bounce) then again i go to test user properties -- email and Add one email [email protected] again u try to send email to t*[email protected]* from internet (email received) i think the only problem is with accepted domain but in hub transport , it shows accepted is there any way to check does domain is properly accepted or not in exchange 2010 server. Thanks

• Remotely port forward/launch process or a client-less remote desktop app?

  I have an XP box running Logmein at a remote location behind a linksys router, which was running well for a whole of four days, until we had a power failure. Our ISP gave us a new IP, the machine restarted, and logmein did not autorun (or, at least, it did not automatically sign in), and our service (which may or may not be a Minecraft server with non-backed-up save files) also did not run upon startup. Logmein does not register the new IP (it still displays the old one). I have a DDNS updater service, so I do know the new dynamic address. I have tried using the built in XP remote desktop service, but, as with almost all non-cloud-based remote desktop services, it requires a port forward. Thus, I would appreciate it if anyone has any ideas as to: A: Any way of accessing our router remotely to forward the remote desktop port. I've seen the Remote Management option (forwarding the setup page to port 8080), but I do not have it enabled. I've tried UPnP, but again, the setup page for our router is not forwarded. B: Any way of remotely launching a process that does not require port forwarding (or uses ports 255XX, 18XXX, or 9000.), such as a remote console service built into XP. I realize this is a near impossibility. C: A Way to remotely start logmein, and sign in, which is likely a definite impossibility. Sorry if this is too specific for Stackexchange, or if I've put it into the wrong section (is SuperUser the correct place for this?). Ideas would, again be much appreciated, as shot-in-the-dark-like this may be.

• Copied a file with winscp; only winscp can see it

  - by nilbus

  I recently copied a 25.5GB file from another machine using WinSCP. I copied it to C:\beth.tar.gz, and WinSCP can still see the file. However no other app (including Explorer) can see the file. What might cause this, and how can I fix it? The details that might or might not matter WinSCP shows the size of the file (C:\beth.tar.gz) correctly as 27,460,124,080 bytes, which matches the filesize on the remote host Neither explorer, cmd (command line prompt w/ dir C:\), the 7Zip archive program, nor any other File Open dialog can see the beth.tar.gz file under C:\ I have configured Explorer to show hidden files I can move the file to other directories using WinSCP If I try to move the file to Users/, UAC prompts me for administrative rights, which I grant, and I get this error: Could not find this item The item is no longer located in C:\ When I try to transfer the file back to the remote host in a new directory, the transfer starts successfully and transfers data The transfer had about 30 minutes remaining when I left it for the night The morning after the file transfer, I was greeted with a message saying that the connection to the server had been lost. I don't think this is relevant, since I did not tell it to disconnect after the file was done transferring, and it likely disconnected after the file transfer finished. I'm using an old version of WinSCP - v4.1.8 from 2008 I can view the file properties in WinSCP: Type of file: 7zip (.gz) Location: C:\ Attributes: none (Ready-only, Hidden, Archive, or Ready for indexing) Security: SYSTEM, my user, and Administrators group have full permissions - everything other than "special permissions" is checked under Allow for all 3 users/groups (my user, Administrators, SYSTEM) What's going on?!

• How to make Microsoft JVM work on Windows 7?

  - by rics

  I am struggling with the following problem. I cannot install MS JVM 3810 properly on Windows 7. When I start Interner Explorer 8 without starting any java 1.1 programs choosing Java custom settings under Internet options causes the crash of the browser. I have some Java 1.1 programs that work well in Internet Explorer 8 on Windows XP after the installation of MS JVM 3810. I know that it is not advised to use this old JVM but it is not a short-term option to port the programs in newer Java since it contains 3rd party components. Complete rewrite is a long-term plan. Strangely jview and appletviewer (jview /a) works from a console so the MS JVM 3810 is not completely busted just IE 8 does not like it. The problem with the appletviewer is that it cannot connect to the server even if both signed and unsigned content in Java custom settings have been set to Enable all. (Since Java custom settings was unreachable due to the crash the modifications - including My computer - were performed through the registry and pre-checked to behave correctly on Windows XP and Internet Explorer 8.) If jview was working then I could at least think of a workaround. Is there a way to configure MS JVM or jview properly on Windows 7? Another options would be: Checking Internet Explorer 9 Beta. Using virtualbox and Windows XP older IE in it. Delaying Windows 7 upgrade. ... Update Finally we have modified all the programs to work parallelly as applet and application as well. This way the programs can still be used from browser on older Windows versions. On Windows 7 the applications are started from the desktop. Installation to all user machine can easily be solved since they already have a large common application drive. The code update is fortunately only a few lines of modification: including a main method in the applet class. Furthermore instead of the starting html page a bat file is used to set the classpath before the startup with jview.

• VPN: Disable class based route addition for Windows XP/Vista

  - by brgsousa

  Paraphrasing this SuperUser link: When you set up a VPN, the Windows default is to enable "Use default gateway on remote network." A new default route is added to the routing table pointing to the remote network's gateway, and the existing default route has its metric increased to force all Internet traffic to traverse the tunnel and use the remote network's gateway. All traffic uses the VPN, and traffic destined for the outside world is directed to the remote gateway. When the VPN drops, the route to the remote gateway is removed and the original default route is set back to the original metric. Unchecking "use default gateway on remote network" means that new default route isn't added, so Internet traffic goes out the local gateway, but a new classful route is added to the routing table, using the local adapter's IP, pointing down the VPN. Only traffic destined for the classful network of the local adapter goes down the VPN. This may not be what you want. Checking "Disable class based route addition" means that classful route isn't added to your machine when the VPN starts up, and you'll need to add the appropriate routes for networks that should be routed through the tunnel. But, the option "Disable class based route addition" is available ONLY for Windows 7. How can I do something like that for Windows XP or Vista since they don't have that option? I have searched about for that but, no solution yet.

• Network bandwidth usage dashboard?

  - by SkippyFlipjack

  I have a couple of wifi access points hooked up to my home network, one of which I keep unsecured for some development I do; there are only a couple other homes within range and they've got their own wifi so it's not a big concern. I also have a Sonos system, Tivo, Roku, a couple laptops, a couple phones, an iPad and a desktop machine, all of which are internet-smart. So when my internet bandwidth tanks and it takes five minutes to load a YouTube video, I want to know what's going on, and there are many potential culprits. I'd like to be able to plug my MacBook into the primary router and see a nice little dashboard of the units on the network and what kind of bandwidth each is using at that moment. I could figure this out from WireShark or tcpdump but figure there has to be an easier way. I've tried a few different commercial products but none really presented the right info. Suggestions? (This may be a question for superuser since my Apple Time Capsule's SNMP capabilities are limited, but I figure admins of small business networks would have dealt w/ the same issue..)
