  Hi, Added this in zone db file, i am running solaris 10 _ldap._tcp.mydomain.com. SRV 0 0 389 dc.mydomain.com. _kerberos._tcp.mydomain.com. SRV 0 0 88 dc.mydomain.com. _ldap._tcp.dc._msdcs.mydomain.com. SRV 0 0 389 dc.mydomain.com. _kerberos._tcp.dc._msdcs.mydomain.com. SRV 0 0 88 host.mydomain.com. Now i get this error when i try to join win xp to the domain The query was for the SRV record for _ldap._tcp.dc._msdcs.mydomain.com The following domain controllers were identified by the query: host.mydomain.com Common causes of this error include: Host (A) records that map the name of the domain controller to its IP addresses are missing or contain incorrect addresses. Domain controllers registered in DNS are not connected to the network or are not running. What do i need to change in order my win xp join the domain

• zeroconf (bonjour/avahi): macs do not see linuxes and vice versa

  - by codesnik

  In my home network I have several OS X boxes and several Ubuntu boxes. each Ubuntu box sees other boxes via zeroconf. I can "ssh ubuntu1.local" and "ping ubuntu1.local" from "ubuntu2.local", but both fail to lookup OSX boxes. and other way around, I can "ssh mini1.local" from "mbair.local". but it doesn't see "ubuntu1.local" why? do ubuntu and osx use different flavours of zeroconf? could be ubuntu, or osx tweaked to use common flavour?

• impossible to connect.. days trying..

  - by dany

  I have a problem: I am on Debian. I configured my nic with a static ip (192.168.1.56). When I try to connect to a network, initially with ifconfig eth2 I get (correctly): eth2 inet addr:192.168.1.56 .... inet6 addr: fe80:221:ff:fe96:4598/64 but after a few seconds the 102.168.1.56 disappears and after some other seconds disappears the inet6 address too. When I press in the nm-applet it requires me the password but in the meantime it try to connect. At uni, the connection is a DHCP one. It works for the first few seconds but after it doesn't. Any possible solution? Here it is the relevant part of the syslog: (static ip configuration) http://pastebin.com/u3BPAsda

• Setup IPv6 over IPv4 tunnel in VPN

  - by bfmeb

  Let me explain my szenario: I have a linux server A. A is reachable in a VPN. So if I am connected to the VPN over Internet I can successfully ping A. Server A is connected to a Router B. Router B has a local ipv6 address and there are resources (each of them with a local ipv6 address) connected to Router B. After I am connected to VPN, I am able to use ssh to have access over A. Now I can use the ping6 command to ping the Router B or one of its connected resources. This works fine. The ping fails if I try to ping router B on my computer. Overview: My Computer -- VPN -- Server A(ipv4) -- Router B(ipv6) -- Ressource A(ipv6) On resource A runs for example a HTTP-Server. My question is: How can I access Resource A (for example with HTTP) on my to VPN connected computer? Is it possible? Should I setup a tunnel device? Sorry for this inexpertly explanation, but I am new to network stuff!

• How can I configure Adobe Help so it doesn't chatter so much with Adobe's domain?

  - by Michael Prescott

  Adobe Help that came with Creative Suite 5 and/or Flash Builder Pro is constantly creating network traffic with an Adobe site, www.wip4.adobe.com In the Adobe Help application Preferences, I find that I can change the settings so that I must manually download updates, but apparently the application still likes to call home and chatter non-stop with www.wip4.adobe.com. I could use something like Little Snitch to block all this spyware-like behavior, but I'd really prefer to just change the application's behavior. Is there a hidden setting or configuration file to adjust this behavior to something more appropriate and polite?

• Ubuntu 12.04 host lookups extremely slow

  - by tubaguy50035

  I'm having issues with one of my servers taking a long time to look up host names. This is an Ubuntu 12.04 box, so I've tried following the new resolvconf directives. In my /etc/network/interfaces file, I defined my name servers like this: auto eth0 iface eth0 inet static address someaddress netmask 255.255.255.0 gateway 198.58.103.1 dns-nameservers 74.14.179.5 72.14.188.5 In my /etc/resolv.conf, I see these name servers, like this: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 74.14.179.5 nameserver 72.14.188.5 On another box, I edited the resolv.conf directly as directed by my hosts' setup help files. It looks like this: domain members.linode.com search members.linode.com nameserver 72.14.179.5 nameserver 72.14.188.5 options rotate This second box has no issues with host name look ups and responds quite quickly. Could not having the domain and search directives make my look ups slow? By slow, I mean it's taking anywhere from 5 to 15 seconds to find the IP address of a host.

• Multiple WAPs: Bandwidth, Frequency Considerations

  - by Pete Cresswell

  The router in my LAN closet does 2 and 5 GHz. In the kitchen, I have a single-band 2 GHz WAP, and in the garden shed I have another single-band 2 GHz WAP. All are set to Bandwidth = 40 MHz, Wireless Network Mode = N-Only. The kitchen WAP and the LAN closet router both come up with multiple bars on my smart phone from almost anywhere in the house. The garden shed WAP will register one bar... but only sometimes. The Questions: Are these things in danger of butting heads? Should I re-set them to Bandwidth = 20 MHz? Bandwidth = Auto? Are there any tools that I could use on an Android smart phone, iPod, or WiFi-enabled laptop to make my own analysis?

• Rsync over NFS with QoS: How to view real transfer speed?

  - by Ian Mackinnon

  We have a bandwidth limit between a Linux server and a NAS, created using 'tc' with an IP filter. When writing to an NFS mount of the NAS, rsync claims a very high transfer speed for each file and then waits a long time before acknowledging that everything has finished. The total time taken is consistent with the QoS limit and the time taken by the same transfer over FTP. Why does the write to the NFS mount report higher transfer speeds than are actually happening over the network? How can I monitor the actual bandwidth of the transfer?

• Comunication from Server to Client + Client LAN

  - by Filipe YaBa Polido

  I'm having some trouble with some network setup. I've tried OpenVPN, SocialVPN, Hamachi, still it is not working. This is my setup: Server A: NIC 1 with internet public address, NIC 2 to LAN Client B PC: NIC 1 (192.168.10.2) connects to router 192.168.10.1 Client B Device: 192.168.10.3 (Configured via software, can't do much here) Problem: Server A must connect to cliente device B. (I can install software needed at Client B PC). However... I can't change the router to some model with VPN like Draytek or Cisco :( OpenVPN fails at bridging, PC B can ping Server A, but Server A can't ping Device B, only PC B. What else can I do?!?!?

• Gnome 3 - Unable to change date and time

  - by Chris Harris

  I am running Arch Linux with Gnome 3. Unfortunately, although my time and date settings in /etc/rc.conf show that HARDWARECLOCK='UTC' and TIMEZONE='America/LosAngeles'. I continue to get the timezone of Europe/London. If I try to change the date and time via the GUI. It requires root access. After authorizing root access, the date and time may be changed; however, after closing the GUI window, it automatically reverts back to the previous incorrect timezone. I am able to use pool.ntp.org in order to sync my time to the correct one; however, this works only for the current session and is not fixed. This solution is inconvenient since there is not always network access. What other solutions are available for this problem?

• Homegroup and NTFS permissions

  - by bytenik

  I'm running a copy of Windows 7 as a "server" at my home. I have several file shares that I want to make available to specific users only. I've modified the NTFS permissions to only allow these users to access their respective shares. However, while a locally logged on user can access the actual folders just fine, over the network the remote access is authenticating as HomeGroupUser$ rather than the actual user in question, as shown by the Computer Management panel for shares. I do have matching user accounts (i.e. my username locally is abc and a parallel account with username abc and the same password exists on the server machine). I don't want to disable homegroup because there are other shares where homegroup authentication would be desirable, especially for some people where they don't have a parallel account. Is there a way to get the system to authenticate first by matching username, and then by homegroup authentication if there's no matching user?

• cygwin rsync over ssh very slow

  - by Waleed Hamra

  I have 2 machines running Windows Xp SP3. I have cygwin installed on both, version 1.7. I have rsync and ssh installed on both, and configured using default settings as per ssh-host-config and ssh-user-config programs provided. I moved the public keys into their respective locations, and basically ssh is working fine. i began an rsync operation, using: rsync -av --delete --hard-links local_dir username@other_machine:/some_dir well... on both machines, the processor is running near idle, no heavy usage. I checked IO using process explorer on both machines, and that too is at normal levels (1~2 MB/s), so I can't see where the bottlenecks are, because network performance is aweful. I'm not going over 1MB/s... when a normal file copy using windows sharing achieves some ~10 MB/s.. What could be wrong?

• Server 2003 RAS Server Utilising High WAN Traffic

  - by Joe Sergeant

  We have Routing and Remote Access configured on Server 2003 (also our primary domain controller), allowing users to connect in remotely to access files, email, etc. With one user, the RAS Server is constantly sending data to that user's remote computer. From 9am this morning it has transferred almost 800MB. The user isn't transferring any files remotely, certainly not enough to total 800MB anyway. None of the other remote users have had this issue. We have ensured that the user in question has "Use default gateway on remote network" disabled for both IPv4 and IPv6 and we are fairly confident that Offline Files isn't trying to synchronise with the server remotely, too. My question is two-fold. Firstly, has anyone had a similar experience? Secondly, what would be the best software to discover exactly what data is being sent to the remote user?

• How to proxy and encrypt all my internet traffic with Win7 and Win2008R2?

  - by Malartre

  I have a Windows 7 laptop and a Windows 2008 R2 server. How can I encrypt and route all my internet request from the Win7 laptop to the Win2008R2 server? I guess the server would be called a proxy? Goal is to prevent unencrypted network snooping. I found this article about using SSH, but I would prefer an official windows integrated solution. What's the Microsoft "way" on this? http://lifehacker.com/237227/geek-to-live--encrypt-your-web-browsing-session-with-an-ssh-socks-proxy I would like this to work for all internet traffic, not just browser traffic and I would like to set this up on many Win7 clients.

• tradeoffs of iSCSI vs. AFP when using Time Machine with a NAS?

  - by ajit.george

  I'm setting up a home NAS device (Synology DS409) that I'm planning to use for Time Machine backups (amongst other things). What are the tradeoffs between using iSCSI or AFP to mount the backup volume? The Synology wiki suggests that iSCSI is better if the Mac will be frequently disconnected from the network or sleeping, from the point of view of the volume automatically remounting. What about filesystem consistency? Given that unplugging a USB drive without properly unmounting it often requires the Time Machine volume to be repaired, would iSCSI have the same issues? Thanks in advance.

• Restarted computer, now wireless and Visual Studio is broken

  - by Earlz

  I installed the new update for TortoiseSVN which requires a restart. Upon restarting a lot of things broke. I'm currently running a virus scan, but what would cause this? Among the things that no longer work is Visual Studio. It now says "Invalid License Data. A reinstall is required" and my wireless internet does not work. When I go to connect to my network it will say "Can not connect" and then when I diagnose the problem it says "The connection to accesspoint-name was cancelled" (and yes, canceled is misspelt like that) What could have caused this? My computer did not install any updates or anything like that upon restarting and it was running fine before I restarted it.

• iTunes randomly plays songs while importing, and can't be stopped

  - by Steve Bennett

  I'm importing a gazillion songs over the network into iTunes. Every now and then, it starts playing the song it's currently importing. And because iTunes is basically frozen up during the import process, I can't actually stop it. Then it will suddenly jump to another song a bit later on. Pretty irritating. Is it a known issue? Anything I can do about it? Versions (oops): iTunes 10.5 (141), OS X 10.6.8

• rdiff-backup failed due to target machine being down, but is unkillable

  - by Markus

  My backup script was invoked by cron, using rdiff-backup to backup the user files onto a target system in the network. That target computer went down at some point, yet still appeared as mounted on the server. rdiff-backup didn't do anything, but still appears as a process. kill-ing doesn't stop it. Similarly, running rdiff-backup for other directories works but doesn't exit properly and remains in the process list. Is there anything short of rebooting the server that I can try?

• Help with proposed iSCSI SAN VMware implementation.

  - by obsidian

  We have four (with plans to grow to four more) Dell servers with 6 NICs. They are running VMware ESXi 4.1. We would like to connect all of them to an Openfiler iSCSI SAN via HP ProCurve 1810G switches. Based on the design below, is there anything I should be concerned about or anything unusual that I should look out for when making the iSCSI network configurations on the servers, switches and OpenFiler? Should I bond the connections on the servers or simply setup them up for failover? The primary goal is to maximize IOPS. Thanks in advance.

• Virtualizing Firewalls/UTM

  - by TheD

  So Sophos UTM (Astaro Gateway UTM) can be virtualized in Hyper-V, VMWare, vSphere etc. Now I'm new to virtualization, so am wondering how the networking would be configured in this situation. Imagine the following (a very simple setup). A Zyxel router acting as the default gateway, standard ADSL line. This is connected directly via Ethernet to my VHost, Hyper-V in my case. Now I assume I need two virtual network adapters, one which is the "External" interface to the firewall, and the other being the "Internal" interface. But where does my switch go, since I have 5 machines (or X number of machines). Where is the switch connected, to the internal interface on the VHost? What default gateway do my clients use etc? How would the routing work if these two interfaces weren't bridged since they are virtual networks anyway. I'm a little confused! Any advice is much appreciated! Cheers

• Shooting Print Quality Pictures with a Camera Phone [Video]

  - by Jason Fitzpatrick

  Camera phones get a lot of grief for being underpowered but in this video tutorial the crew at SLR Lounge shows how basic technique and a good eye overcome all. Last year over at the photo blog FStoppers they put together a video showing off how you could use the iPhone as a fashion camera–essentially arguing that the camera wasn’t as important as the photographer. A lot of people said “Well yeah, but you had professional models and thousands of dollars in lighting equipment!” in reaction to the video. In turn the crew at SLR Lounge decided to make their own video showing that using only an iPhone camera and two reflectors (as well as an attractive but informal model). It of course helps to have some side kicks to help hold up your reflectors but the point still stands about modern camera phones being perfectly capable of good photos.

• Slow write speeds on new Gigabit home file server

  - by Ryan Holder

  So I finally got all my parts delivered to setup a home file/backup server this week. It's currently running Ubuntu Server and I'm using Samba to share files on my network. The server currently has a 2TB WD Green drive in it connected to a Asus M5A78L-M This is then connected via CAT6a to my new Gigabit switch (TP-Link TL-SG1005D). My home desktop is then also connected to this switch and again also through CAT6a cable. Currently when transfering files I will get a perfect 100MB/s read from the server to my Windows machine. When copying from my Windows machine to the server I get around 30/38MB/s. I know this drive is capable is faster speeds so would anybody have an idea of where the bottleneck is? Any help would be greatly appreciated :) EDIT: I have found ftp's write speed is much closer to what my Samba read speed is so I'm going to give it a guess that is a software problem rather than hardware
