• Switch to switch encryption over a wireless bridge (TrustSec?)

  - by metatheorem

  I am planning to connect an existing Cisco 3750 switch to a 3560C switch over a wireless PTP bridge. The bridge will be WPA2 protected, but I am looking for an additional measure of security between the switches to prevent other wireless access through either switch. They do not support IPSec, only 802.1Q tunnels, and buying additional hardware is not likely an option. I am looking into using TrustSec manual mode between the switches. After some effort reading into TrustSec and MACsec, I am mostly certain this is a good choice over the wireless bridge, keeping in mind it is a shared medium. Two questions: Can I reliably prevent other wireless traffic from accessing the switches using TrustSec? Does anyone know of any better options with the 3000 series switches?

• IIS7.5 Domain Account Application Pool Identity for SQL Server Authentication

  - by user38652

  In Windows Server 2003/IIS6 land we typically create an app pool that runs as the identity of an AD account created with minimal privileges simply for that purpose. This same domain user would also be granted access to SQL Server so that any ASP.NET application in that app pool would be able to connect to SQL Server with Integrated Security=SSPI. We are making a brave move to the world of Windows Server 2008 R2/IIS7.5 and are looking to replicate this model, but I am struggling with how to make the application pool in IIS7.5 run as the identity of an AD account? I know this sounds simple and hopefully it is, but my attempts so far have been fruitless. Should the application pool identity be a 'Custom account' for a domain account? Does the domain account need to be added to any groups?

• Windows Security popup window pops up each time any connection is made

  - by MC Emperor

  I have a problem with the Windows Security popup below. It pops up every time the system tries to make connection with any internet source. It's very annoying, and I don't know how to resolve the problem. (The popup window below is in Dutch, but says something like Connect to somedomain.com. Then it expects you to give your credentials.) I am running on a Windows 7 x64 OS. Now how do I solve this problem? Is it a Windows Firewall problem?

• Why is my system using port 4?

  - by Kathleen

  I have Windows 7 and have noticed that my system is using port 4 to connect to a lot of different IP addresses. When it connects to them it is not for very long before it moves to another IP address. One night I sat and wrote down as many as I could and started checking whois to see where they were and they were from all over the world. I don't understand this. When I did a search on the net with this question. The only info I could come up with was, that port 4 is used by the US Army and a list of port assignments listed it as "unassigned". If anyone has any clues to what is going on... I would greatly appreciate any info I could get.

• proxy server software for windows xp

  - by This is it

  Hi Is there a proxy software for Windows XP that can support HTTP, HTTPS, SMTP, IMAP, POP, FTP, etc. (the more the better)? We tried apache mod_proxy but FTP doesn't work through it (at least not all features). Maybe we don't need proxy server for following requirements (we are open for suggestions): - Centralized access point to internet for several users (proxy server?) - Users use Browser (firefox/IE - HTTP, HTTPS), Outlook (SMTP, POP, IMAP) - Logs to see where did users go on internet - Possiblity to connect to FTP server Windows xp, which is used as proxy server, is a virtual machine, and all other users/clients are virtual machines as well (Hyper-V)... Thanks for suggestions. Cheers

• Tabbed terminal that connects to a GNU Screen session?

  - by screenuser

  I use the session feature of screen extensively. For example, I'll start a screen session for "project1" as "screen -S project1", and then when I need to reconnect I use "screen -d -r project1". This makes it easy to manage multiple projects, each with their own set of shell sessions. What I would love to do now is that when running on Windows and Linux, to be able to use a tabbed terminal program (such as gnome-terminal) to connect to a screen session and have all of the screen windows split out to separate tabs. This way I get all the usual power of screen, but with the convenience of a richer GUI experience. Is there any such terminal program available on Windows and/or Linux?

• Downloads speed starts ok but after a few seconds they go down to 10kbps?

  - by peterg

  Since yesterday any file I try to download from any host start downloading ok (at 1mbps) but after a few seconds the speed start to decrease down to 10kbps. I use a mobile modem (huawei) and I connect to a wcdma network. What could be happening? I use kaspersky, and I checked the Network Monitor and I don't see any weird process using bandwidth. What other tests can I run? Recommend me some app to monitor the traffic to see if I have some malware or see where my bandwidth goes.

• Can't resolve Mac's machine name on VPN

  - by Raghuveer

  My mac'c machine name is something like this: hostname.company.com but whenever I connect to VPN, it becomes something like vpn-xxxx.company.com where xxxx are some random numbers. Because of this, some of my scripts which are dependent on host name gets blocked. We use the standard mac's vpn setup which comes with OS X Lion (under network preferences). How can I resolve to the correct mac's name even if I am on vpn ? That is even if I am connected to VPN, my machine name should resolve to hostname.company.com and NOT to vpn-xxxx.company.com. Any suggestions would be really appreciated.

• After creating a mysql user with all privileges, the user cannot create databases in phpMyAdmin and only sees information_schema table

  - by GHarping

  This is a recurring problem for some reason... Using mysql 5.5, I am simply trying to create a user that can connect to the database remotely, have access to all databases, and create databases. I have created a user using: create user 'dev'@'%' identified by 'abcdefg'; then granted all permissions using: GRANT ALL ON *.* to 'dev'@'192.168.%' IDENTIFIED BY 'abcdefg' WITH GRANT OPTION; and the result is that the user cannot create databases, and can only see information_schema database for some reason. Databases Create database: Documentation No Privileges Database Ascending information_schema Total: 1 Does anyone know why this might be happening?

• centos 5.6, virtual on Vsphere

  - by Glasnhost

  suddenly my virtual centos server (5.6 on VMWare-VSphere) is not working... It started with the url not responding, nor the ip. (NO HTTP response, no ping). When I entered on the server via ssh to start troubleshooting I noticed that most of commands don't work anymore: top- machine hangs (it's not slow anyway) ps - machine hangs (funny enough apache server and web app are running and sending me emails) on some directory ls -l - machine hangs after first file, if ls l.txt the file show only the first file "more" command, also hangs on some file. So there are very little things I can try. I recovered my virtual machine from yesterday and before yesterday, and they show the same behaviour, it hangs on commands (but yesterday they were working). There is no firewall on the machine, there is on the host though. I can connect with ftp but I can't download files nor list directory apart the user top directory... Working hard right now, any idea appreciated

• Extremely poor WiFi reception on new desktop

  - by guy

  I just received a new desktop with a built-in WiFi card (Windows 7 Home Premium x64). However, I am only able to receive any WiFi signal when the computer is within 1-2 meters of a router. Even then, the signal is very weak (Windows 7 says it is "poor"). I have tried this with 2 different routers and see similar results. I have somewhere around a dozen other devices that can connect to both routers with greater signal strength (usually full strength) from much, much further away. When I tried calling support I was instructed to reinstall my drivers and attempt to change the WiFi channel of the router. Neither worked. I was then told that the problem was with my routers and that the computer was functioning normally and that it was certainly not a hardware problem. What would be the cause of this and is there anything I can do to fix it?

• How to restrict access to other Wifi networks in range?

  - by meetpd

  Is there a way to access connecting to other wifi networks in range? I have an office and there are few wifi networks in range. Some of them are not password protected and invariably I get connected to that wifi first. I have talked to the person who owns that wifi. But he is somehow not listening about adding password to his network. So, is there a way I can block that Wifi network completely so that I do not connect to it? I have Win 7 and Mac at my office.

• Windows 7 RDP Fullscreen mode

  - by kubal5003

  I have a problem with remote desktop connection in Windows 7. When I connect to remote computer I would like to switch to fullscreen like I did in previous versions - just by clicking maximize. When I was in fullscreen mode and I moved the mouse to the upper border of the screen a nice bar appeared and I could minimize rdp or close it. In Windows seven when I click on the maximize button the window maximizes like a normal window - menu start/taskbar(whatever you call it) is still visible and because the resolution of the rdp client desktop is set like on the computer that I'm using it's not fully visible and scrollbars appear. That's really annoying. Can anyone tell me what to do? Is it a bug or maybe there is a "magic shortcut" that is poorly documented and does the trick? (I was trying to find it myself first ofcoz, but no result)

• Windows 7 - saved wifi access points disappear from list

  - by KáGé

  I'm having a weird issue with Windows 7 x64: I'm moving my notebook between two locations weekly, at each I have a wifi router. They both have hidden SSID-s, which are different. If I save one, the other one gets deleted from the list, as if overwritten, so I always have to retype the SSID and password, if I want to connect after moving my computer. At first I tought the problem was caused by both routers having the same password, but after I changed one (suffixed it with "_2") it persisted. What can I do about this? Thanks.

• is there a cheatsheet for linux commands to save your system?

  - by Asaf

  I've recently lost my window options, had to somehow manipulate my way to Xchat and ask some people how do I get it back (it was metacity --replace, and after I decided to stop the command and run it in background the X was completely useless so I had to do killall -u user). And that was after the internet connection stopped working for some reason (might've been the ISP) ..The thing is, after using linux a long time, I still get the feeling that on dire situations, I don't know the good tricks (stuff like metacity --replace) I feel like a really need like a "rescue" cheatsheet for things like "how to save the X no matter what without pressing reset" and "how to reset the system to "normal state"" "how to connect to the internet through the command line" "how to monitor what the X is doing" (using ubuntu linux 10.04 btw)

• No sound Ubuntu 12.04 through HDMI

  - by MikeMan

  Specs: Asus G73JH i7/720; ATI Mobility 5870 I have read through a lot of threads on getting HDMI sound to work and non of them have fixed my issue. Granted I am very new to Linux and know only the GUI aspect of what it does from finding similarities that Windows 7 has. I would like to become a Linux Power User and I figured this would be a good step to get started. I was able to successfully install my graphics driver and it shows in use. I connect the HDMI to my HD TV and I get no sound. I don't care about auto switch for sound, that would be great but not necessary. I just want my sound to work through the HDMI. What I have tried: Changed GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" pact set-card-profile 0 output:hdmi-surround Failure: no such entity Sound Settings: Right-click Sound indicator ? Sound Settings ? Output Tab, and set Digital Output (S/PDIF) Built in Audio Speakers Built in Audio I only get 2 settings. If I right-click the area below those 2 in the "play sound through" box, I get no "show hidden devices". I am also doing all this with the HDMI connected to eliminate any possibility for error.

• Long domain lookup on .dev domain inside vmware

  - by skelle

  I'm developing on my macbook and normally I have a local running webserver which just works finde. Now I have to use a vmware image where the webserver is running. I set up everything and my dev site is running under site.dev inside vmware. I can connect to the webserver but EVERY request takes a very long time. I already red that this is related with iIPv6 and the way OSX handles /etc/hosts. There I added 192.168.155.42 site.dev and I already did this (Resolving to virtual host very slow on Mac OS X Lion) but my lookup still takes ~30seconds on every request. What can I do to fix this issue?

• Windows doesn't recognise my USB key anymore (it used to work)

  - by dominicbri7

  I use my friend's USB flash drive (Corsair flash voyager 16gb) to transfer files from my laptop to my desktop computer. However, since a couple of days my laptop stopped recognizing the USB key.. while there is still no problems with all other computers. I use Windows 7 64 bits if that can help. I tried uninstalling the driver, rebooting and all those kind of tricks, but it won't work. When I connect it and open the "My computer" window, I see "Removable Disk (G:)" for a moment, then it disappears... then it reappears again and it keeps doing that periodically. I can't even right click then hit "Properties" because it disappears. As I recall, it DOES work on every other computers, I think it has to do with the driver but what can I do?

• Stop ssh client from offering all the public keys it can find?

  - by Rory McCann

  Like most sysadmins I use openssh all the time. I have about a dozen ssh keys, I like to have a different ssh key for each host. However this causes a problem when I am connecting to a host for the first time, and all I have is a password. I want to just connect to the host using a password, no ssh key in this case. However the ssh client will offer all the public keys in my ~/.ssh/ (I know this from looking at the output of ssh -v). Since I have so many, I will get disconnected for too many authentication failures. Is there some way to tell my ssh client to not offer all the ssh keys?

• VPN stuck on Verifying Username and Password

  - by user2791

  I'm building a new machine and everything is working correctly, except that I can't log on to my VPN. It hangs at the "Verifying username and password..." step, then returns after about 30 seconds claiming Error 721. I have another machine sitting next to this one with the VPN connection configured exactly the same, connecting just fine over the same wifi network, so I'm convinced that there is no server or firewall problem. The VPN works fine. This machine simply can't connect to it given the correct credentials and configuration. Any suggestions?

• Cannot Login as root

  - by Josh Moore

  At my work we ship our product on pre-installed servers as a software/hardware package. We are using open SUSE 10.3 for the OS and we setup and we always log in with the root user to do maintenance on the box. Recently we just had box returned to us that the customer said the could not longer connect to the box through the network interface. So when I started to work on the box I run into the this problem: At the command prompt to login i type the user name "root" and hit enter. Then even before it asks me for a password I get "Login incorrect". I have never seen this behavior before and could not find any information about it online. Does anybody know what is going on? Thanks.

• What ports do I allow over my internal firewall interface?

  - by blsub6

  I have a Cisco ASA that I have VPN tunnels to connect my internal Windows network. I ran into some trouble logging into my domain so I unblocked all the ports on that internal interface. On a previous question posted here, the general consensus was that I should be blocking ports on my inside interface but my question is: what ports should I unblock? I've tried unblocking ports 88, 139, 135, 389, and 445 and Windows logins still give me problems. Is there some MS documentation somewhere that tells me what I need to unblock to allow Windows logins and other things?
