• dist-upgrade broke my insatll HELP

  - by diefuchsjagden

  so I ran apt-get update; apt-get dist-upgrade the upgrade failed and I lost the gui, I have an encrypted /home drive. When I run apt-get * (any command) I have all kinds of errors mostly missing depends and thats because apparently my network stack is gone. I have no NIC if I run ifconfig. It doesn't even show up with lspci If I were to do a "clean" install of 10.04 LTS which is what I had on my on my build, will I lose all my data? BTW I was just using Ubuntu's default encryption to manage the encryption using my PSWD as the key so if I were to use the same user name and PSWD would my data be accessible? I can see my data from command line, when or if Xorg does start it just loads a basic window with nothing but a black X in the middle of the screen which I can only assume is my mouse cursor but it doesn't move! Reddit /r/linux had some ideas none of which worked was, no help. And apparently /r/ubuntu is full of jerks because all they did was ridicule me. If I can get my install back I probably will be switching back to either Slackware or Gentoo. The Ubuntu forums were of no help they had the same suggestion as /r/linux. I am about to just run my back up script to my back up drives and nuke everything else but I'd rather not.

• Netgear routers don't allow you to disable wireless admin??

  - by MousePad

  I just bought a new router, the NetGear WGR614. Nowhere in the settings can you disable the ability to administrate the router from a wireless connection, which opens it up to brute force attacks from outside the building. Furthermore, it doesn't require a direct connection to the router to admin either, you can admin it while you're connected to the Internet. This means it opens itself to the possibility of an attack from within the network. This is unbelievable to me. What am I missing? Can this be possible?

• Why no final dot for domain names?

  - by user41150

  I recently learned that a fully qualified domain name ends in a dot, e.g. www.microsoft.com.. Why do I almost never see this? We casually toss around www.microsoft.com, a relative domain name, without a second thought. It's not mere pedantry, because it seems there's a security issue: someone in your network could create www.microsoft.com.example.com. to hijack your requests to www.microsoft.com. Why doesn't the internet community have a tradition of using genuinely fully qualified domain names?

• VLAN Configuration Conflict, Who Wins?

  - by Kevin

  I'm new to VLANs, so take that into consideration... Lets say that I had a server set up to create a virtual interface that is set to be tagged as VLAN 3. For example, the following Debian config: iface eth0.1 inet static address 192.168.1.1 netmask 255.255.255.0 Now on my switch, lets say that I have the port that the aforementioned server connects to, set to VLAN 4... Who wins? What are the packets tagged as, as viewed by the rest of the network?

• is it possible to use multiple proxies for different target websites?

  - by fduff

  Typically I'd like to know if it's possible to have a setup where it maps some IPs with a particular proxy and other IPs using another proxy? Proxy Chaining isn't really what I'm looking for (well I don't think it is) because each address could be resolved with or without a proxy but their content may not be accessible without the right proxy. This setup could be part of home network, so that the relevant proxy s/w could be installed and setup on a Linux box for ex. Ex: website-A via proxy-1 website-B via proxy-2 all others via no-proxy

• Why can't my FreeBSD 6.1 (vmware player client under Win7) do DNS in Bridged mode.

  - by Walter Stickle

  I have a 64-bit FreeBSD 6.1 client, running under Windows 7 (64-bit) via VMWare player 3.0, with networking set to bridge mode. DHCP goes fine on boot... I get correct adress/gateway/nameserver info... I have good connectivity to the world in that I can ping any host I can name by IP addr, (including both of the nameservers in resolv.conf,) ...but I can't resolve any names. Inside the Windows box, the network interface has VMWare Bridge Protocol enabled, and the windows side of things has full connectivity. dig replies with: ;; connection timed out; no servers could be reached ...even if I use "dig @server_ip_addr" to point it at a pingable, working nameserver If I set VM networking to NAT mode, I can get outbound connectivity (with happy DNS) but, of course, can't do INBOUND connectivity, which I need. Thoughts?

• Sending email with Windows 8 Mail (Modern UI) being blocked by AVG Firewall

  - by Riaan

  I've setup my Outlook.com email address in Windows 8 Mail (Modern UI) but is unable to send and receive emails when my AVG Internet Security 2012 Business Edition's Firewall is enable. When I disable the firewall, the emails are coming through and are being send. I know that I can most probably open the ports for IMAP on the firewall, but instead I would like to permit the application. Where/how do I find the application path for Windows 8 Mail (Modern UI) to allow all network traffic? (AVG did not show its normal Allow/Disallow notification for 1st time communications) Any advice would be appreciated.

• Finding a way to enter gmail in Company

  - by stckvrflw1

  Hello all, I am entering network over DNS's of my company. Here my company blocks lots of IP's for reasons like entertainment, sports, music, messaging boards etc. General e-mail is also one of those topics and I can't enter gmail.com.

Also I am not able to enter the gmail from Igoogle too, this is also blocked. How can I enter gmail ? Thanks.

• Domain in a hosted environment

  - by cpgascho

  We have an application we host in a third party data center for our clients. We have multiple clients running the same application on several racks of servers. Most of our clients require that our servers be SAS70 compliant. Currently each server has it's own set of users and security settings that need to be configured. We are creating scripts to do this, but what would be the risks/advantages of joining all the servers to the domain for User Management and Group policy for enforcing security settings? The rational of some is that if the DC is hacked the whole network would be compromised where as if one stand alone hosted server is hacked everything else should be safe.

• Mac OS X multi-user thin client server (terminal server)?

  - by username

  Is there any solution out there to turn a Mac into a true multi-user thin client server? I'd like to set up a few cheap PCs with access to a couple accounts using something like VNC, but it isn't economical to buy a new server for each user or a new license for virtualized OS X Server for each user. I'm fully aware that OS X Server lets you set up users with "network home folders," and I know there's also VNC built into Mac OS X. Neither of these fit the bill (the former requires a thick client, and the latter is single-user only) UPDATE: yay, Lion! http://www.9to5mac.com/54102/10-7-lion-allows-multi-user-remote-computing

• VPN on PC vs Mac

  - by allstar

  I am trying to connect to a VPN from my home computer, as opposed to my work computer which already has the network info set up. I have received instructions on connecting from a mac, but since I don't have that I'm trying to do the equivalent on my PC. I know the: server group name secret and my own login account and password Using the Windows 7 VPN, there's space for: Internet address destination name user name password domain (optional) I'm trying to determine what's what. I assume the internet address is the server. I've tried using the "secret" as the Password, b/c i'd think the first part is connecting to the VPN as opposed to logging in. It still wants a user name though. I tried mine, I tried the "group name". I would appreciate your help with this. Thanks!

• VMware vSwitches and spanning tree

  - by dunxd

  I have two redundant core switches I want to connect to a new vSwitch I am setting up on a VMware ESX host. The switch will have two physical NICs each of which will connect to one of the core switches. The core switches are connected. If this was a physical switch, I would worry about connecting it to both core switches, because this would create a network loop. Do I need to worry about this for a VMware virtual switch? VMware's documentation says it is not possible to connect two vSwitches in a loop, therefore STP is not required. However, I am worried about connecting two physical switches together via a vSwitch.

• Upgraded to Mountain Lion, now 127.0.0.1 is not resolving

  - by Shanimal

  I used to be able to type 127.0.0.1 (or my network IP 10.10.53.32) and it would resolve to my "default" virtual host. 127.0.0.1/~Shanimal and shanimal.dev both resolve to their appropriate folders. localhost and 127.0.0.1 give me a 404 - "Not Found The requested URL / was not found on this server." Basically, my "It works!" screen no longer works. /private/etc/apache2/Shanimal.conf: <Directory "/Users/Shanimal/Sites/_www"> Options Indexes Multiviews AllowOverride AuthConfig Limit Order allow,deny Allow from all </Directory> hosts: 127.0.0.1 localhost 127.0.0.1 shanimal.dev

• Where do I find a free (open source preferably) VNC management tool?

  - by thenior

  Hello, I am trying to get remote internal setup for our business. Basically, I just want to remote desktop into any computer on the network. I don't want to use LogMein, because I only want it to be internal for security. Basically, I am looking for a way to just install VNC clients on all the machines, and on my machine have centralized manager for all the machines that are connected to it. Doesn't have to VNC - just needs to work and be free. All systems running Win 7 64bit

• Enterprise Data Center System Admin/Engineer to Server Ratio

  - by Bob

  I know there have been similar questions asked over the last few months however looking at a Data Center Operations and know there are some really smart people out there that might be able to help. Looking for some staffing best practices based on first hand experience and was hoping that there is some experience in this area that can provide "best practice" application: Three High Availability (99.99% plus) Enterprise Level Data Centers geographically dislocated, one manned 24x7x365, one lights out, one co-location running HOT-HOT-HOT supporting a global community. More than 2,000 operating systems consisting of 95% Windows, 5% Linux and Solaris, 45% virtualized, more than 100TB storage. No desktop support, no Network Administration (administrated separately), running N+1 and serving more than 250 Billion page views annually. Based on experience what has been your experience with Server to "Data Center System Administrator/Engineer" ratio? Thanks in advance for your responses.

• Is it possible as an Administrator to gain access to a SQL Server 2008 instance without changing any passwords?

  - by adhocgeek

  I have administrative access on our network, but I don't manage the installation of all servers or software. On some of our machines instances of SQL Server 2008 have been installed which I need to be able to access, but since my account hasn't been explicitly granted a login, I can't get into. Is there a way to get into the database without changing anyone's password (e.g. I could solve this by changing the password of the user who installed the instance, assuming they've set themselves up as admin, and then logging on as them, but I don't want to have to do this).

• Synced audio ouput on multiple machines? VLC? hardware solutions?

  - by zimmer62

  I'm wondering if there is any software or hardware solutions to synced audio or audio and video across multiple computers or devices on a network. I've seen Sonos, and it might be a good solution, but it's also a very expensive solution. I'd like to be able to play something with realtime audio output on one PC, but hear it on speakers throughout the house, being it the home theater receiver, or another computer in another room. I saw a solution using the apple iport express, but the latency was unacceptable for anything other than just music. I'd like to avoid running audio wires with baluns to a bunch of amplifiers scattered all over the place when I have cat5 run everywhere. Is anyone familiar with using this kind of process for whole home audio? The latency is a big deal for me, if I've got video attached to the sound (e.g. watching a hockey game)

• Sharing files from my Macbook to Windows Desktop

  - by Vahe

  What's the most dependable way to share files and folders on a OS X to Windows (I'm using 7). I've followed this guide: http://support.apple.com/kb/HT1812 However, this method does not seem dependable (Works only some of the time). My Macbook does not always show up under the Network on Windows. On certain occasions, turning off windows file sharing completely (in OS X preferences), restarting my Macbook and turning it back on helps. Is there any reason why this is happening? Is there an alternative method?

• How to set up server to be accessed from mobile devices [closed]

  - by Kgrover

  I need to set up a server that will eventually be accessed from an Android application. I don't have experience with how to go about this, but I've seen MySQL servers (Amazon EC2). I would need to store data on the server remotely (again, from a mobile device) and fetch it to display. What would be the best kind of server to use? I'm guessing I would only need around 50 GB of space. Is it possible to use a network drive and set that up as a remote server with an IP address? I would need to upload and extract data through java on Android. This is my first question on ServerFault, and I'm not sure if it's the appropriate forum. If not, please redirect me.

• Masquerade traffic from certain source IP to VPN connection

  - by Shuo Ran

  Network Setup: 10.0.0.1 Router: to internet 10.0.0.70 Server: Ubuntu based server,default gateway is 10.0.0.1 10.0.0.51 PC I created a PPTP connection(interface: ppp0) on Server to a machine on the internet, what I want to do is route all the traffic from certain IP address(10.0.0.51) through the PPTP connection and then to the internet. What I did are: Set the gateway on PC(10.0.0.51) as 10.0.0.70 Enabled ipv4 forward on 10,0,0,70 Add the masquerade rule to iptable: iptables -t nat -A POSTROUTING -o ppp0 -s 10.0.0.51 -j MASQUERADE After that, it seems none of the traffic from 10.0.0.51 be redirected to ppp0, instead these traffic are still going through 10.0.0.1 directly. Any thoughts on it?

• Unable to run Django on Mac OS X

  - by cybervaldez

  I'm working with a Django project on my Mac (running Leopard) and I want to show it to my team. I've already passed the neccessary port forwards from my router to my Mac's LAN IP address but it doesn't work. I've also tried running the XAMPP server since that always worked with my Windows XP computer but it still doesn't work. Whenever I type my > it's showing a Page Load Error. Is this possibly an issue with an Mac OS X configuration that I need to setup first to allow my port forwards to get in? It's my first time to do this with Mac, perhaps I need to configure something else in network preferences?

• Windows 7 cannot connect wirelessly to Netgear Router WPN824 V2

  - by edo152

  I have a new HP Laptop running Win 7 Home Premium with an Atheros Wireless card. I have a Negear WPN824 V2 Rangemax Router. The router works with a wired connection. Wirelessly it can see the network but it cannot connect. I have searched the web and the WPN824 seems to work for some people, but I cannot get it to connect. I have tried disabling Bonjour Service and a few other things but it continues not to connect. Am I probably correct to assume that the WPN824 is somehow incompatible with Wiondows 7? or am I missing some simple change I should make?

• How to get a windows domain server to recognize a linux machine by its name?

  - by CaCl

  In my company I ran into an issue where we have a linux machine that serves up a Subversion repository. Its hooked up via LDAP to the Active Directory. We got an account setup for an application and they set the Limited Workstations up so it didn't have full access to the network. The problem is that even though the hostname for our machine resolves correctly for me, the credentials for the application account seem to come back as not being allowed based on the name (the error was related to authorized workstations). I don't have access to any of the domain servers but it might be helpful to come at the management or high-level techs with some ideas, they don't seem to have a solution besides allowing all workstations for the user. Does anyone have any idea on how to get my linux machine to properly identify itself with the Domain machine by name?

• How can I move authorized applications between google accounts?

  - by zoopp

  I'm looking into creating an email address with a professional name on gmail and due to the fact that I can't change my current one I have to create new google account. Among some things which which need to be patched (eg. forwarding email to the new address until every other account's email contact address is changed etc.) I came across authorized applications. If I am to use exclusively the new email address I have to somehow move my authorized applications as well since if I am to eventually delete my old account I will lose access to my current profiles created by those applications (eg. the stackexchange network, youtube etc). How can this move be accomplished?
