• Recognition of USB drive

  - by lamcro

  I have a Motorola phone, with a MicroSD slot, which my Ubuntu machine does not recognize as a USB drive. It does know there is something there since It automatically charges my phone whenever I connect it. using the command lsusb shows it as "Motorola PCS" Is there a way to tell Ubuntu/Linux that the connected hardware is a disk drive?

• Wirelss card not being detected in backtrack 5

  - by Jesse Nelson

  I just installed backtrack 5 and I am unable to detect my wireless card. iwconfig doesn't list my interface. I can see that the hardware is present in lspci -vnn (see below) but I can't get the interface detected. I have tried to reinstall the compat-wireless package but I get errors during the build (see below) I have done a ton of researching and I keep hitting a brick wall, mostly because the wiki for backtrack is down and I can't find any good resources. Does anyone know how to fix the issue? Also, does anyone no how I can scan the hardware to determine what NIC is assigning my interface? If I can figure out the interface name I think I can set it up manually by putting up the link and using wireless-tools to manually configure the connection, this is what I had to do in arch on my mac. As stated the wiki for backtrack is down and I can't find any help on the issue. I tried to do the full kernel upgrade suggested in my software update but after the update was complete and I logged back in I had a new log in manager and the only thing I was able to log into was window managers. However, after this update my wireless was working fine. Please help I am new to Linux and the wiki is down, I have nowhere else to turn. Forgot to mention I am using the KDE version, not Gnome. Thanks in advance for any help or support.

• Documenting Client Infrastructure

  - by Richard B

  Working on a new project, and need some documentation advice. I need to be able to document ~ 400 client sites to track assets, setup, hardware layout, network layout, etc. We want to have photos, maps, etc. wherever possible. We need this for a call center environment. Has anyone found any off the shelf software that performs this functionality, or are we on our own to develop the tools that we require?

• Cannot connect to telnet server

  - by BloodPhilia

  So, I can't use telnet to connect to any server but it works fine from a different computer. It just says it can't connect. I tried the following things: Disable firewall and AV protection. (Basically, there was no security feature left online) Telnet is set to "Trusted" in my AV protection. (Kaspersky Internet Security 2011) Using Putty to telnet, but apparently Putty's connection is also inhibited. (Says it can't connect to host) Disabling the telnet client in Control Panel and then re-enabling it. (Windows 7 Ultimate) hosts file is clean. Checked for nasties using MBAM and KIS 2011 as well as going though my HijackThis logs, nothing found. I can connect to the same machines/servers through the web browser, ping, tracert, etc. Only telnet seems to be blocked. Any other thoughts?

• iptables question

  - by RubyFreak

  i have a small network, with one valid IP and a firewall with 3 network interfaces (LAN, WAN, DMZ). I want to enable PAT on this valid IP to redirect http traffic to a server in my DMZ. (done) I want to enable MASQ on this ip from traffic that comes from my LAN (done) I want from my LAN as well to access my http server at DMZ. (partially) Question: in the above scenario, i cannot from my LAN, to access my http server in the DMZ, since it has the IP used by the MASQ (the only valid ip that i have). What would be the best option to solve this problem? network interfaces: eth0 (WAN) eth1 (DMZ) eth2 (LAN) /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE /sbin/iptables -A FORWARD --o eth1 -d 2.2.2.2 -p tcp --dport 80 -j ACCEPT /sbin/iptables -t nat -A PREROUTING -i eth0 -d 1.1.1.1 -p tcp --dport 80 -j DNAT --to 2.2.2.2 /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT /sbin/iptables -A FORWARD -i eth2 -o eth0 -j ACCEPT

• Steps to make sure network is not blacklisted...Again

  - by msindle

  I have an interesting issue. I have a client that just got blacklisted due to spam being sent out over the last 2 days. I have my firewall configured to only allow mail to go outbound on port 25 from our mail server (Exchange 2010) exclusively and I have verified that there are no open relay's on our transport rules. We are running Vipre Business and after running deep scans with updated definitions all computers come back clean. I ran a message tracking report on our Exchange server that shows all mail sent via the mail server over the last couple of weeks and didn't see anything malicious or out of the ordinary. I have also verified that there are no home devices or rouge computers on the network. For all practical purposes it appears that the network is clean, but we still wound up on 5 or 6 blacklists...Where should I start looking next? Is there a "best practices" guide that can help eradicate this issue? Thanks in advance! msindle

• Putting a Windows DC, Exchange in a DMZ

  - by blsub6

  I have one guy at my company telling me that I should put FF:TMG in between my main Internet-facing firewall (Cisco 5510) and put my Exchange server and DC on the internal network. I have another guy telling me that I should put the Exchange server and DC in a DMZ I don't particularly like the idea of having my mailboxes and DC's usernames/passwords in a DMZ and I think that Windows authentication would require me opening up so many ports between my DMZ and my internal network that it would be a moot point to have it out there anyways. What are some thoughts? How do you have it set up?

• Third-party Information Screen Opening Blank

  - by Jacob

  I'm working with a client who is trying to use our software, which accesses information (sends & receives) from a third-party website. When this client tries to access these pages, a window opens, as expected, but is completely blank and no error message is received. This is the first time I've seen this with many other clients successfully using this product, which leads me to believe that it has something to do with the settings on the computer somewhere, but cannot figure out what might be happening. Windows Server 2003 R2, Standard Edition, Service Pack 2. Firewall is already off. Tried AVG on & temporarily disabled.

• Why can't my networks reach each other?

  - by HOLOGRAPHICpizza

  We have two Buffalo WZR-HP-G300NH2 routers, with the default firmware, DD-WRT v24SP2-MULTI (10/31/11) std - build 17798. Each has a separate cable internet connection with a public static IP address. They are both in the 24.123.68.0/24 space. Both of them can contact pretty much the whole internet, and they can both be accessed out on the internet with no problem, but for some reason they can't talk to each other! When I try to ping one from the other I always get "Destination Host Unreachable". There are no strange routing or firewall rules in place. And they are both set to respond to pings, I can ping them from outside. Our main IT guy is going to call our ISP on Monday, but I'm impatient, so does anyone have any ideas?

• Feasible to use a laptop as a Digital Media Receiver/Extender?

  - by philosaur

  Since the price of many dedicated hardware Digital Media Extenders is only slightly lower than that of a cheap laptop, is there any reason you couldn't use a laptop as a Digital Media Extender? I'm looking for specific reasons that might make this unworkable. For instance, would the small screen/low-power video card of the laptop prevent the movie from playing well on the TV?

• How can I turn my server box into an internet modem?

  - by Robbie Mckennie

  I've been trying to learn about networking, network maintenance, network administration, stuff of that nature (I want to be a network engineer when I get out of university after I get out of high school) and I want to set up my older PC (running Slackware) as a modem, as a project to help me learn. I want to know what kind of hardware I'll need. Pretty much all I know is that my current modem uses ADSL2+ and PPPoA, which I think is a software thing anyway. How can I accomplish this?

• After installing Windows what should I do first? update or install antivirus?

  - by EApubs

  Normally, after reformating and installing Windows 7, I used to go online and install all the updates, install all the driver updates and then install the anti virus. Because long ago, when I installed the anti virus first, applying windows updates crashed the AV! So, I install it last. Specially 7 sp1 is critical right? But now im having doubts... Going online without an antivirus means I'm vulnerable! (I have a home router which have a small firewall but I'm not sure about it) So, whats the best thing to do? Install the anti virus first or install the updates first?

• Remote desktop connection drops before login can appear

  - by Keatly

  Hi Everyone, Someone asked this question a few months ago and I have the exact same problem. I have tried all of the suggested solutions in the other posting (in particular reinstalling the video card on the server), but have not had any luck. I have gone through this troubleshooting guide in detail with no results: http://theillustratednetwork.mvps.org/RemoteDesktop/RemoteDesktopSetupandTroubleshooting.html I have a client with Remote Desktop enabled that I can't connect to in our local network. When I enter in the machine ip/port in the connect box and hit Connect, it briefly gives the normal "Connecting..." dialog box. However, after 2 seconds it just drops. No error message, nothing. Just disappears as if nothing was happening. •Windows XP SP3 •Windows firewall is open for 3389TCP •Machine is on a domain •RDP is enabled in My Computer •User is a local admin I have loads of other machines on the same domain with the same GPO that work fine. Any ideas?

• Google Drive desktop client not updating existing files from other users

  - by cqm

  I've looked around and there doesn't really seem to be any troubleshooting information for the Google Drive desktop client. It all assumes you are using Google Docs on the web. Anyway, my team is trying to use Google Drive like Dropbox, where multiple people are editing files shared amongst them through the desktop, such as images. Dropbox is really good at noticing when a checksum for a file is changed, and syncing it. Google Drive's desktop client seems not to do this at all. Google Drive desktop client seems to only sync newly created files and not giving any notification at all that there is a modified version, it will never sync it, even though going online and opening that file will show the modified version. Is there any way to fix this? and the answer has nothing to do with proxy or firewall configurations. Team is using computers running OSX and Windows.

• Recommendation for a touch-enabled dev laptop

  - by Clay Shannon

  I don't keep up with hardware much, so would appreciate any tips on what would be a good touch-enabled laptop that I could use for both development and testing of Windows 8 ("Metro"/Store) apps. Is there even such an animal (a touch-centric laptop)? Or will I need to use a laptop for development (in which case I might be able to upgrade my RC version of Windows 8 on my existing laptop to RTM) and purchase a tablet for testing?

• VMware 1.0.1 Windows7 - Ubuntu hostnames

  - by Kyle K

  I'm trying to run Ubuntu as the guest OS using VMWware 1.0.10 with Windows 7 Ultimate as the host OS. I had this set up previously with Win XP as the host OS and in fact I'm using the same .vmx My problem is I can't get either Win7 or Ubuntu to be able to ping the other by hostname. After installing Samba and Winbind on Ubuntu, I was able to get this working when under WinXP, but for some reason I can't get it to work under Win7. I can ping by IP Address, and the guest OS even shows up by hostname under the Windows networking panel (but of course I can't do anything with it), but pinging using short hostnames just won't work. Also, Win7 firewall is turned off completely.

• iPlanet Authentication provider

  - by Travis

  Good day. I have stepped into project that requires a server migration that would change the means of authentication for our CAC/PKI SSL enabled website. We are using iPlanet 7 and Oracle Directory Server Enterprise 7 as our LDAP server. The situation is that the site is still CAC/PKI enabled, but at the firewall. The information we want to authenticate against is now in the http header. How do I configure iPlanet and LDAP to authenticate against the header instead of SSL? Thanks. Edit, Can this be done with IIS keeping the Directory Server EE LDAP in tact or is the ACL iPlanet only?

• NAT Error Message - Usage limit exceeded

  - by Kato

  Trying to configure a port to use for Vuze. Using the NAT/server port test, I was getting a message saying the connection timed out, the port was probably closed. I went back and made sure to open the specific port on my router, firewall, etc, but now I'm getting "NAT Error - Usage limit exceeded (173.32.41.24:0). I'm on a mac pro running leopard, trial versions of intego netbarrier and virusbarrier. Network utilities and netbarrier both claim the port is open. I've tested a bunch of other ports, but all give the same message.

• External hard drive is recognized but not mounted in OS X

  - by Sam Bryant

  My external HD got unplugged without ejecting and my Mac will no longer mount the drive, but it recognizes it's there. I already tried repairing the disk in Disk Utility, and erasing it in Disk Utility, and it still won't mount. I can't imagine the hardware is actually damaged otherwise it wouldn't even recognize it (Right?). Is there any other software solution I can try? Recovering my files is not a concern.

• Reverse KVM solution

  - by aksamit

  I need to setup a computer so that it can be operated from two locations. The locations are about 20 meter from each other and the user wants the experience to be the same from both locations, i.e. no remote desktop or anything like that and preferably a seamless switch. So basically I need a double set of, monitor, keyboard and mouse, and then of course link it together by some kind of suitable hardware.

• Why does sshd give a different identification when connecting through netcat?

  - by Robbie Mckennie

  I have been attempting to create a way to ssh into a machine hiding behind a firewall. I set up my ssh client with the option Proxycommand /usr/bin/ncat -l 2000, and then I connect it to sshd with ncat <client> 2000 -c "sshd -i" on the server. It works in that I can get a shell on the server, but the server sends a different key than when I use normal ssh. So the question is, why? Is the key different when sshd is called in this unusual way?

• Can I use BitLocker on a Windows 8 Tablet? How?

  - by Coderer

  I hear that Windows 8 Pro can use full disk encryption. I also understand that Win8 is targeting the "slate" / "tablet" form factor specifically. But all my previous experience with BitLocker requires you to put in some kind of PIN or password at boot time -- how can I do this without a (hardware) keyboard? This preview of an upcoming Win8 tablet mentions BitLocker but doesn't address the PIN issue. Am I missing something?

• Windows 7 wifi reports "no network access" and "no internet access" but connects in fedora

  - by rick2047

  I am running windows 7 home basic (64bit) on a Acer 5742G laptop with Atheos wifi adapter in it. Yesterday, I hiberneted my computer as I always do and up untill then the wifi was working fine. When I booted my computer up again today I started having a strange problem: It detects my wifi but after connecting to it, it keeps on oscillating between states of no network access and no internet access. I can't connect to anything (the internet or my router). I tried to reset my internet protocol stack using this fixit file. I also tried to uninstall and reinstall my network driver. Neither helped. I am using the same laptop's fedora installation right now and the wifi is working perfectly fine. Please help. Edit To add additional details, I have Microsoft Security essentials as my antivirus software and I haven't messed with the firewall or the router configurations.
