  • Problem in listening to multicast in multihomed Linux server

    - by Lior
    I am trying to write a multicast client on a machine with two NICs, and I can't make it work. I can see with a sniffer that once I start the program the NIC (eth4) start receiving the multicast datagrams: y.y.y.y. (some ip) - z.z.z.z (multicast ip, not my eth4 NIC IP) UDP Source port: kkk (some other port) Destination port: xxx (multicast port) However, I can't get those packets using my program (listening to port xxx on eth4). I also added: route add 224.0.0.0 netmask 240.0.0.0 dev eth4 Searched the web for some examples/explanations, but it seems like I do what everybody else does. Any help will be appreciated. is there anything else to do with route/iptables?

  • Router block some sites

    - by Mahesha999
    Hi I was using ADSL Modem/Router earlier. The device is quite old Pronet PN-ADSL 101 E/U model (pics: http://bit.ly/P2YaWy, http://bit.ly/OA700l) Since it had only one RJ45 out, I bought new Wireless Router TPLink TL-WR941ND. It has 4 RJ45 out and 3 wireless antennas. I configured my old router in bridge. Now, if I have to connect my pc to Internet through the old router, I have to enter username and password. Then I connected the RJ45 output of old router to the WAN in of new router. and ran the CD of new router. It configured the new router in PPPoE by saving the username and password in router to dial automatically. So now I have to just plug in the wires in my new routers any RJ45 out. I am able to access the Internet when I connect through new router (both wired and wirelessly), but some sites are getting blocked. Most notably yahoo.com (though ymail.com is working), Microsoft.com. msn.com. These sites work perfectly fine when I connect my pc directly to my old router and enter username and password manually. (However others like google.com. facebook.com works fine when connect through new router) So here these some sites need some parameter set but I am unable to find them out. Can anyone help me. My friend said he also faced same problem. Surprisingly he advised me to see if the same websites will work through Opera turbo mode and boom they worked. So what could be the problem?

So I use the 'getmac' command to get the MAC addresses. But which address shown by 'getmac' above is the one matching the MAC in the sticker on the back of my laptop? Or am I mistaken something? 00-21-... is the ethernet adapter, 00-22-... is the wireless adapter, and 72-03-... is what?

  • How to share a VPN connection in a VMWare Guest VM with the Host

    - by Jonathan
    The need - This question is relevant for all of those who want to bypass their corporate's annoying VPN, and access their work/corporate network from their private computer, especially if the corporate VPN client software can't run on their private computer. Homework: this question is very similar to this one and this one, which aren't answered :( The challange - Can't run the corporate VPN client from the private computer, so converted the work laptop to a VMWare Virtual Machine. The VPN client is working fine inside the Guest VM, now we want to share it with the Host (the private computer) The specs: * The private computer (Host OS) is Mac OS X Lion 64bit * The corporate laptop (Guest VM) is WinXP 32bit, running in Bridged network mode * The VPN client on the Guest VM is is Checkpoint SecuRemote NGX R60 HFA03 * While the VPN is running in the Guest VM, the Host can still ping the Guest and vice versa

  • WEIRD netstat behavior on Windows XP re: www.partypoker.com

    - by tbone
    I really don't know if this is the right place to ask this, but I would really appreciate if someone that is more savvy on Windows XP (Professional) could help me out. For background, I am a 10+ years programmer, so I'm not a total idiot, but I am far from an expert on TCP/IP, etc, and this has me totally confused. When I do a netstat (on Windows XP) I seem to always get a huge amount of www.partypoker.com connections and I can't figure out where they are coming from. A netstat -o shows me that some are coming from PID xxx, which is firefox, but if I kill it, the connections still remain. Some are coming from PID 0, which makes no sense to me. SECOND PROBLEM: One would think you could edit the C:\WINDOWS\system32\drivers\etc\hosts file to block this, but it seems like my machine is ignoring the hosts file! (I have tried with the DNS client service both enabled and disabled, same result). So I just rebooted, killed all my normal programs, and I can't seem to reproduce the problem. If I was a paranoid person, I would think there was some sort of an intelligent trojan running. I am running Windows XP Pro, Kaspersky Antivirus, ccCleaner, and am fully up to date on Windows Update. What gives???? So, I guess my questions are: 1. Is anyone else seeing these wird connections to partypoker.com? 2. Why isn't my hosts filter working? 3. Is there some utility I can run to find out whats happening? I've tried autoruns.exe from sysinternals but don't see anything interesting. Am I the only one with this problem? If there are any additional things you need me to run, let me know.

  • Is it possible to force a credential check every time a network share is opened in Windows 7?

    - by Logan VanCuren
    I am running Windows 7 Ultimate and I have mapped a network share to a drive letter. The first time that I open the share, I am prompted for login credentials as expected. I do not select the "Remember my credentials" checkbox and can login successfully, but every time that I re-open the share during the session, I do not need to re-enter my credentials. Is there any way to force a credential check every time that I re-open the share? I do not want to perform a reboot every time that I want to "re-lock" the share.

  • Windows XP only loads in VGA mode, and crashes when raising resolution

    - by Harel
    My kid's computer (Windows XP, SP3) started to (what appears to be) crash on boot. It will only boot in Safe or VGA mode, and if I try to raise the resolution from 640x480 it just reboots itself, and a error appears in the Event Log. When it loads up not in VGA mode, the monitor shuts off just after the windows logo is shown. It seems like windows is actually running but I can't see anything on screen (monitor is off for lack of signal). Nothing was installed recently that I know of, short of the usual windows updates. Thanks, Harel Below is the event log error: Event Type: Error Event Source: System Error Event Category: (102) Event ID: 1003 Date: 15/04/2012 Time: 16:27:11 User: N/A Computer: ----- Description: Error code 1000008e, parameter1 c0000005, parameter2 f745b0bf, parameter3 ede24f98, parameter4 00000000.

  • Problems Installing Windows Server 2008 R2

    - by ProfKaos
    I've just finished 3 day download (with breaks) of Server 2008 R2, and am very eager to install it on my dev machine (my laptop, an HP Pavilion with a 2xTurion 64 cpu). If I mount the ISO and try and run Setup.exe, I get told Setup.exe is not a valid Win32 application. I tried burning the ISO to DVD (as files), but my machine wont't boot from DVD. If I re-insert the DVD, so that autorun comes into play, I get told something like "the setup is not valid for this version of Windows" Any suggestions as to what I might try, either to diagnose the problem, or to avoid it?

  • Synchronize read/unread status for Thunderbird RSS

    - by giorgian
    I've tried several online RSS readers, but I didn't like any of them. I'm quite happy with Thunderbird, but I hate to have to manually mark as read articles I've read at home when I'm at work and vice versa. Is there a way to synchronize the status of read/unread articles between Thunderbird installations?

  • Typing Japanese on Windows Vista with Dvorak

    - by Ken
    I'm using Windows Vista, and I type English with the Dvorak keyboard layout, and I want to be able to type Japanese text that way, too. I've figured out how to set it up to let me type Japanese here, but it uses QWERTY. What I've got so far is: click the "EN" in the taskbar, and select "JP" if the letter that appears in the taskbar is "A", hit alt-~ to change it to "?" type as if I was typing Romaji on a QWERTY keyboard, (e.g., left pinky home row, right ring finger top row), and hiragana appear (??) press spacebar to convert to kanji (e.g., ?), and return to accept That all works great, but it assumes I'm on QWERTY, which isn't very comfortable for me. I want everything the same, but to be able to type kana with Dvorak (e.g., left pinky home row, left ring finger home row - ??). I can do this on Mac OS, so it's not an unheard-of feature. But it was kind of an obscure setting to find, so I figure on Windows it's probably a really obscure setting. :-) But I haven't been able to find it yet. Thanks!

  • PC shut downs automatically after 10-20 second. No POST screen, no beeps

    - by emzero
    I have this not-so-old computer that's not being used for a year or so. Specs: Motherboard: ASUS PN5-E SLI CPU: Intel Core2Duo E4300 RAM:2x2GB SuperTalent DDR2-800 VGA: Zogis GeForce 7950GT PSU: Vitsuba San-55-S 550w HD: No hardrives yet When I power on the computer, everything seem to start, but right away the whole system shuts down. I've removed and changed the RAM sticks, take out the VGA, everything I could think of. So what could it be causing this? The PSU? The motherboard is dead? The CPU? Any help to isolate the problem will be useful. Thanks PS: Please don't close the question, this could be helpful to anybody having a similar problem, even with different hardware. UPDATE I've removed the old thermal paste and apply a brand new one. I also cleaned every dust using a high pressure gas dust remover. Checked for bad capacitors, all of them seem ok. Opened the PSU, removed big giant dust balls, cleaned with high pressure dust remover. Still the same problem, but now it stays powered on for almost 20 seconds maybe. But no POST screen, no beeps at all, nothing. So I suspect it's a motherboard or PSU failure. Unfortunately I don't have an energy tester to test the PSU... Don't know what else to try. I don't have another 775-motherboard to test the CPU, RAM and VGA with it.

  • How do I find and replace 'whole words only', in Microsoft Word?

    - by user277816
    I want to be able to find and replace eat with Eat in Microsoft Word 2007. However, I don’t want to replace every occurrence of eat such as those that can be found inside other words such as great and meat. I have tried doing this using the regular Find and Replace tool, but I get words with capital letters in the middle. Is there a way I can just replace eat with Eat if it only exists on its own?

  • When my printer fails to print with only "printer error" as the message, how can I find details?

    - by lavinio
    Setup: Dell Latitude D620 in the docking station HP color laserjet 2550L Parallel cable Sometimes when I undock (and I do suspend before undocking and docking), when I reattach, the printer will not print. It simply says "error", with no description. Killing and restarting the spooler will not help, but rebooting will. There is nothing in the system event logs, nor does the print spooler window provide any details other than "error" My question is, when there is an error, is there any way to find out what is causing it to get stuck, so that I can "unstuck" it instead of rebooting?

  • Error opening microsoft.com in Windows 7

    - by Ilnur
    I need help with my browsers. In Windows 7 Basic I have 2 browsers installed: Internet Explorer 8 and Google Chrome. When I try to open pages which are associated with Microsoft (like Live and others), my browser crashes; Internet Explorer 8 crashes too. But Opera (I've installed it later) works fine with those pages. P.S. I tried to scan my PC for trojans and viruses, but it's clean.

  • Choosing the right e-mail client

    - by CFP
    Hi all, I'm currently using Outlook 2007 (under windows 7), but I much prefer free software (open source being the best of course), so I thought I'd ask for expert advice here. I thought it might be easier if I included a small "wanted list": I receive about 15 to 30 e-mails every day, but I have large archives (10'000 emails), which I frequently need to access. I usually open and close my mail program many times, so I'd like it to start pretty fast I cannot use an online mailbox, because I have too many email addresses (about 5: 1 for work, 1 for home, 1 semi-private, 1 for specific emails, and 1 for newletters By order of importance, the things I'd like my mail client to be able to: Efficiently categorize e-mails. Until now, I've mostly been using Outlook folders, because filtering by tags was not easy, but I'd rather one large list of mails, neatly tagged so I can easily filter. I'd love being able to select mails by tags (eg in a click or too (could be a tab) show all mails tagged with "software") Create "tagging rules", such as "if the mail was sent to this address, add this tag", or "if the body contains ..., add that tag" Sync contacts with Gmail, handle tasks (syncing with toodledo would be awesome), possibly provide a calendar Create e-mail templates, signatures... Other ideas: A timeline, scripting support, being able to import MS Outlook emails, provide a nice backup format... Thanks for sharing ideas and suggestions!

  • Cannot set video resolution above 640x480 after installing Windows XP SP2

    - by waanders
    I've installed Windows XP SP2 on a computer (there was not SP at all). Now the display settings are set back to 640x480 and 4 bits colors. And I can't change it, it's the only option in Settings tab of the Display dialog of Windows. The screen look awful now, how can I solve this problem? UPDATE: Seems to be a problem with the video driver (thanks @Karan and @Hennes).
