  • Where should I go to learn about networking? [closed]

    - by Ollie Saunders
    I wonder if anyone could recommend resource or resources such as a good book that: explains how all the important protocols work and interact. I’m interested in those that are relevant in a typical home network and used over the Internet explains in detail how ADSL Internet connections work to the level of depth necessary so that I’m able to tweak and measure performance settings starts from the beginning but attempts to provide proper understanding rather than idiot-oriented steps to follow Basically, I’m interested in how these technologies work and tend to be implemented in hardware and software rather than “here’s what to do if…” I’m interested in Computer Networking by Andrew S. Tanenbaum and I wonder if anyone else has any experience with that title. It’s expensive but I could probably loan a copy for £3 from the library or so.

  • Why do I get "Permission denied (publickey)" when trying to SSH from local Ubuntu to a Amazon EC2 server?

    - by Vorleak Chy
    I have an instance of an application running in the cloud on Amazon EC2 instance, and I need to connect it from my local Ubuntu. It works fine on one of local ubuntu and also laptop. I got message "Permission denied (publickey)" when trying to access SSH to EC2 on another local Ubuntu. It's so strange to me. I'm thinking some sort of problems with security settings on the Amazon EC2 which has limited IPs access to one instance or certificate may need to regenerate. Does anyone know a solution?

  • Not receiving bounced emails from PHPList

    - by user1780242
    I am sending a test campaign to my own address and to a fictitious nonsense address and I am receiving the email at my account but I am not receiving any bounces. My settings in the config.php file are: $message_envelope = '[email protected]'; $bounce_protocol = 'pop'; $bounce_mailbox_host = 'localhost'; $bounce_mailbox_user = '[email protected]'; $bounce_mailbox_password = 'XXXXXX'; What's the next step in figuring out the problem? I also tried both variations of the following: $bounce_mailbox_port = "110/pop3/notls"; #$bounce_mailbox_port = "110/pop3"; I am running a Godaddy Centos 6 VPS and Plesk 11.

  • Change my MX record on my server to google MX?

    - by Dejan.S
    Hi. I got a windows server 2008 where I host a site, now I decided to have the email on google apps. I did add the MX records I get from them to my DNS settings on the server but with no luck. I recently started doing server stuff so I did like this. Server Manager / Roles / DNS Server / DNS / SERVERNAME / MYDOMAIN / Forward Lookup / New MX Host or child domain: What goes here? FQDN: here is my domain name, i think because I named the ns my domain? FQDN MX: here is the google MX record I got from them MSP: 10 I have no Idea where I go wrong but I thought I would ask you guys if any of you can maybe give me some tips on what to look for or any newbee mistake I do that you see from this little info. I really appreciate all help I could get on this.

  • Paste a list of dates in format of "mm/dd/yy" to iWork-Numbers

    - by David.Chu.ca
    I have trouble to paste a list of strings in the format of 'mm/dd/yy' into iWork-Numbers. For example, I have a list of strings(text in VIM): 04/01/10 04/03/10 04/13/10 I copy those strings and then paste into my iWork-Numbers worksheet. The result will be: 2004-01-10 2004-03-10 04/13/10 It looks like that Numbers (mac workseet application in iWork) tries to convert the first two digits into year, then the next two into month if less than 12 and last two digits to a day, for the first two rows. For the third(04/13/10), since the middle two digits are 13 and cannot be a month, then this row is pasted as it is (actually it is what I need). Is there any way to paste whatever as they are, without any "smart date conversion"? Do I have to change settings in Numberers or Mac OS's System preference?

  • Microsoft IME + Japanese: Force Hiragana input by default?

    - by Mica
    I am using Windows XP SP3 and Windows 7. On both machines, I cannot make Hiragana the default input method. Is there a way to do this? In the IME tool bar, there is the option to set the "Input Mode." This is always defaulted to "Direct Input." I would like to default to Hirgana or Katakana. I have found the setting dialog for this, by right clicking on the IME toolbar - settings - Japanese IME Standard - Properties - Default Input Mode. This setting seems to have no effect, no matter the combination of selections in the dialogs. Is there a way to reliably set the default Input Mode?

  • Command window missing default 8x12 font

    - by Robert Koritnik
    Installation: Windows Server 2008 R2 Remote Desktop Service role When I logon locally my command window (cmd.exe) displays with default font that is 8x12. But when I logon remotely and open command window, it opens with the smallest possible font selection. Opening window properties and setting font size, the default 8x12 font is missing from the list. What should I do to get this font back in the list? Following screenshots show settings when logged on locally and remotely. Local machine is not Aero capable, but remotely I can have Aero environment. I've also tried setting it to basic, but there was no change. Local logon Remote logon

  • Format (remove) HDD volume that is visible in Windows 7 Disk Management but not diskpart.exe

    - by EntropyWins
    I'm trying to get iRST working on a SSD I installed in my lenovo u410. As part of that process, I created a hibernation partition and was fiddling around with RAID/AHCI settings. I managed to make my computer unbootable. No sweat, I just restored it with Lenovo's 1 key system. Now, however, I can't do anything with that hybernation partition! I can see it: (It's the 7.81 GB partition). But when I try to delete it in Diskpart.exe to reclaim the space and try the formatting again I only see this: I can't do anything with the partition in Disk Management either. Right clicking only shows the 'help' option. Can anyone suggest a way to edit these partitions with windows or, at least, reccomend a program that might help me fix this? Note, I'd rather not delete the 16 GB OEM partition that I believe holds the backup for this computer.

  • How to view only Mail on shared email account?

    - by TomatoSandwich
    I have a support account which I should have access to in my Outlook 2010, however, since changing from 2003, the situation has become unusual. I used to be able to just view shared mail items in a seperate account, without it having the Calendar, Tasks and Reminders popping up in my face all hours of the day. Now, if I add the account, I get upwards of 60 task reminders that are not my personal account, and that clog up my Reminders window and task list. Is there a way to show only my Tasks and Reminders in Outlook 2010? I've tried the Advanced Filter option on the Tasks list, but if I set it to show only things from or to myself, everything disappears, or nothing disappears. I tried looking in the email account settings for something like 'Read email only' or something to do with only showing some of the modules of outlook, but it was useless.

  • Digest authentication not working: endless cycles of asking for user/pass

    - by bcmcfc
    I'm trying to setup my SVN repository for access remotely. In doing so I have some settings under Apache's dav_svn.conf file. When navigating to hostname/svn, or using Tortoise to do the same it prompts for the user name and password as expected. However, when entering the correct user name and pass that were set in the password file linked to under AuthUserFile it just asks for the credentials again. I think I'm probably missing something simple? The server is running Ubuntu Server 9.10. Accessing SVN remotely does currently work if the authentication lines of dav_svn.conf are commented out. These are the contents of the dav_svn.conf file: <Location /svn> DAV svn SVNPath /home/svn/repo AuthType Digest AuthName "Subversion Repository" AuthDigestDomain /svn/ AuthUserFile /etc/svn_authfile Require valid-user </Location>

  • Disabling a touchpad in Windows

    - by Shamaoke
    I want to permanently disable a touchpad in Windows running on my laptop, since firstly, I use a mouse, and secondly, when I work, I often touch it accidentally what causes definite inconviniences. I tried the following approaches to disable it but with no result: Turned it off through BIOS — there's no such function there; Turned it off through the touchpad configuration utility — there's no such function there; Turned it off through the device manager — the disable button is inactive; Turned it off through a hotkey (Fn + F1 in my case) — the hotkey doesn't work; Uninstalled the proprietary driver — Windows automatically downloaded the standard driver; Uninstalled the standard driver and turned off the automatic driver download function (Win + R ? "systempropertiesadvanced" ? Hardware ? Device Installation Settings) — all the same, Windows downloaded and installed the driver. How can I disable a touchpad? Windows 7; the Alps touchpad.

  • why would you create two different subnets on the same physical network?

    - by xirtyllo
    I'm working at a messy location, one of the strange (for me) things is that on the same physical network there are two different subnets. Specifically some computers will have 10.0.0.0/24 and some others will have 172.16.0.0/24. There is only one DHCP server, which gives IPs on the 10.0.0.0/24 range, and there are two internet gateways, one with IP 172.16.0.1 and one with IP 10.0.0.1 . To give an example, I can easily swap one PC from one subnet to the other just by changing its IP and gateway settings. I am trying to imagine why they created the network this way, and which may be the possible advantages and/or drawbacks of having two different subnets on the same physical network. Any thoughts?

  • What should be taken into consideration when deploying Windows 8 in a domain environment?

    - by GaTechThomas
    Edit: Reformulating the question: We have ordered new laptops but before they arrive, our development team is trying to decide whether to install Windows 8 or stick with Windows 7. We have already tested on isolated machines, but we have not yet been allowed to add the machines to the domain. Before we approach the networking group to discuss adding Windows 8 machines to the domain, we need more information on what changes / issues to expect in moving from Windows 7. Are there any aspects we should consider that are specific to Windows 8 clients? Thus far, I've gotten the following feedback: Windows Administrative Shares are disabled New set of Group Policy templates Changes to proxy server settings Additional items along these lines would be helpful. We're not looking for items related to Windows GUI changes, but instead primarily items related to having the machine live and be used on the domain.

  • Why is my firewall preventing me from accessing some websites

    - by nosx
    I have an old Belkin router and when I enable the firewall I cannot access certain websites. For example: http://www.avisynth.org With Firewall Enabled: Main page loads and begins to do a meta refresh which never finishes. With Firewall Disabled: Main page loads and the meta refresh completes as normal and I am taken to the wiki page. I have not setup any rules in my firewall that would prevent this site from loading, yet it refuses to load unless I have the firewall disabled completely. My router has a hidden page with advanced settings on it for the firewall which I was able to acccess and take a screenshot of, but I did not want to mess with these values unless I absolutely have to do so: What might be causing this problem and how would I go about fixing it?

  • Can not change to a static IP in Fedora 19

    - by user196272
    Im having a bit of a weird situation. Ive installed Fedora Linux 19 onto a virtual machine with no GUI. initially eth0 does not show up when I perform ifconfig. when I run dmesg | grep eth I see the adapter but it says it changed names to p2p1. Once I perform the ifconfig p2p1 up command it shows up. Now when I try to edit the /etc/sysconfig/network-scripts/ifcfg-p2p1, it does not exist. the only scripts that are there lo and enp0s3. If I try to create the ifcfg-p2p1 file with the correct settings, I can not restart the network service. I tried editing the enp0s3 file, but that did not work. Im fairly new to linux and not sure what else to put in here, so if you need any more information just let me know and Ill put it in here.

  • Remote Access Problems with DRAC 5 on Dell PowerEdge 1950

    - by Darin Peterson
    Today I received my first Dell PowerEdge 1950 server with a DRAC 5 card. On my local network I have static configurations on my Linux systems using this for instance: iface eth0 inet static address 192.168.1.210 netmask 255.255.255.0 network 192.168.1.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-nameservers 8.8.8.8 8.8.4.4 For the DRAC card, I configured the LAN like this: address 192.168.1.215 netmask 255.255.255.0 gateway 192.168.1.1 For the advanced LAN settings I used dns-nameservers 8.8.8.8 8.8.4.4 I've tried many different IP addresses, but cannot communicate with the card. Is there anyone who might know if I have configuration issues, or maybe if the card might be bad?

  • Windows AD, bulk user creation, homedrv creation via commandline

    - by Neil
    I am Bulk creating AD users from the commandline (dsadd) and whilst doing so am setting the homedir and homedrv to a DFS location. I observe when I create the user with all these settings via the GUI (dsa.msc) that the homedrv gets created on the DFS share with all the permissions set correctly. But when using dsadd, the folder is not created. How can I replicate this GUI behaviour via the commandline when creating the user? I don't really want to rely on logon scripts to set it up. Do I have to use mkdir and cacls and something else to give the user Ownership? Or maybe I am missing something easy. Any help much appreciated!

  • How can I delete virtual networks from command line?

    - by David Cobb
    I have Hyper-V Server 2008 R2 (without GUI) running at my colo for a week. I was connected via RDP and could use the menu interface and command line. I figured out how to connect Hyper-V Manager from my Win7 laptop (THANK YOU HVREMOTE!), and created and installed my VM. I created a virtual network that didn't work (no connectivity from my VM) so I created another using different settings, and now have lost access to the Hyper-V host. No ping, no RDP. Since I don't have console access, I cannot troubleshoot. I believe if I deleted the Virtual Networks I'd regain access, but I need a command line instruction for this, that the staff onsite could enter to accomplish this. I find no help anywhere obvious (MSDN, etc), the keywords are too general. Can anyone refer me to simple steps how to do this over command line or with the menu based interface on the console?

I followed the third step of this http://learn.iis.net/page.aspx/309/configuring-ftp-firewall-settings/ guide in order to configure my firewall for FTP, and I am able to authenticate, however, the data channel doesn't seem to be passing through the firewall. If I disable the firewall, everything works fine. Hope someone can help me, as this is really starting to annoy me. Best regards, x3ro

  • Multiple IPs on Juniper SRX100 Untrust Port

    - by Will
    I am having trouble getting multiple IP addresses on the untrust port. I have tried a few different methods, but can't seem to get it to work. Does anyone have a good tutorial that is not easily found or if possible can type up the steps? I don't mind trying to do it through ssh, but would prefer web interface. Thank you ++++++++++++ Feb 1 fe-0/0/0 { unit 0 { family inet { dhcp { update-server; } } } } routing-options { static { route 0.0.0.0/0 next-hop 96.11.173.81; } } Right now it's setup to receive settings from 'cable modem' through dhcp, but I think it's only getting one IP.
