• VPN Split Tunneling - Pros and Cons and how to achieve?

  - by Theveloper

  Well this is the dilemma, I want remote clients to connect to my network and only route local access through the VPN. This is split tunneling, the client uses its internet connection for all other internet requests and the VPN tunnel to my network for local requests. There's a couple of issues that arise: split tunneling in Windows is achieved by unticking an option which reads "Use default gateway on remote network" in the TCP/IP settings of the client VPN connection. At any point the user can tick it and route all his internet traffic through my network eating away at my bandwidth and being cloaked by my IP address. This is unacceptable. Issue number 2 is that if the client is split tunneling, he becomes a gateway between the internet and my network, this is also unacceptable. My questions are: how does one achieve split tunneling serverside? And is the latter issue a valid con worthy of worry? Any thoughts would be appreciated!

• Connecting Snow Leopard 10.6.4 to a Linux shared folder using Samba

  - by Vittorio Vittori

  Hi, I'm trying to connect to a web server running on Linux CentOS 5.5 where I've shared a folder. I'm trying to connect to the directory with Snow Leopart 10.6.4 client without success. On CentOS I've started the Samba service and a Samba user with his password and then I've tried to connect to the server with the command smb://10.0.0.7 to reach the IP of the machine and then writing the username and password I've previously created. The server returns me the list of the shared folders with the leopard specific browser, when I click to the folder I want the browser returns this error (translated from Italian): Leopard message: Connection failed There was an error on connecting to "smb://10.0.0.7". Please verify the name or the IP of the server, and try again. How can I do to solve the connection problem?

• Mac OS X Server 10.6.6 DNS not responding properly, get a "Truncated, retrying in TCP mode" for subdomain

  - by Eric Arseneau

  If I do an nslookup on youtube.com, no problem, if I do one with www.youtube.com, failure. See details below. [~] nslookup youtube.com Server: 192.168.1.1 Address: 192.168.1.1#53 Non-authoritative answer: Name: youtube.com Address: 74.125.127.93 Name: youtube.com Address: 74.125.47.93 Name: youtube.com Address: 74.125.95.93 [~] nslookup www.youtube.com ;; Truncated, retrying in TCP mode. ;; Connection to 192.168.1.1#53(192.168.1.1) for www.youtube.com failed: connection refused.

Any recommendations?

• Setting up Linux VPN Client on Mint: Never sends "Set-Link-Info" packet

  - by cabanaboy

  I have tried to set up a VPN Connection on the Linux Mint disto, but could not get it working. When I use a Windows 7 VPN client it works fine. I brought up Wireshark on both Windows and Linux machine and noticed that on the Windows machine, the client never attempted to send the "Set-Link-Info" packet whereas the Windows (working) VPN client did. Why isn't the Linux Mint client sending the "Set-Link-Info" packet. I think if it did that, then my connection would work. What am I missing?

• Linux Mint Wireless doesn't connect [migrated]

  - by guisantogui

  I'm having a great problem, I've installed Linux mint debian edition (LMDE), and following this tutorial http://community.linuxmint.com/tutorial/view/161 I did installed the network driver. The available connections appears to me, but when i try to connect to my connection at first time, I got this message: "(4) Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." And the following tries, I got this another message: "(32) Insufficient privileges." I'm accepting ideas. Thanks.

• rdesktop over ssh

  - by Dan

  In Ubuntu, I'm trying to log into my friend's windows machine using rdesktop. First, I can log into his outward facing linux box using ssh. Then from there I can log into his linux host machine using ssh. This host machine is running Windows XP inside virtualbox. Is there a way for me to tunnel rdesktop through these two ssh connections (may just need the first connection to the outward facing linux box just to get inside the network, depending on how virtualbox's network connection is set up). Thanks

• Losing WLAN connections but maintaining internet connections on WIndows 7 Workgroup

  - by Di

  I have 4 computers all running Windows 7 networked in a Work group through Billion 7404vgp-m wireless router.All drivers and firmware for wireless adapters and router are up to date. Windows Firewall and Defender disabled.Disconnected ipv6. Running Nod 32 anti virus software. All have own static IP address 192.XXX.X.XXX. When I Reset the router all computers have Internet and LAN access for about 1 hour and then they will lose the LAN connection but maintain Internet connection. Resetting wireless adapters or restarting computers does nothing to fix this but resetting router will. What is causing this and how do I fix it. Thanks Di

• Unable to connect to wireless internet(wifi) through KDE plasma desktop

  - by Mohammed Arafat Kamaal

  I installed the KDE plasma desktop through Ubuntu software center. I am on Ubuntu Lucid Lynx. After the install, Im unable to connect to my wifi connection in the KDE session. But I can connect to my wifi perfectly through GNOME session. I've tried a lot without much success. Also KDE doesn't store my password correctly and keeps prompting for authorization again and again. Some of the things that I noticed. Network is detected, Network name and strength is also displayed. Other characteristics also appear properly. When the credentials are supplied, it accepts them and continually displays the message "Setting network address". However this process never succeeds. At this stage the password is repeatedly asked many times but the connection is never established. Some of the other things that I did, I have also tried other things like restarting my modem and the computer. That didn't work. I tried to restart nm-applet and KNetworkManager. That didn't work either. ifconfig display all my interfaces and Mac addresses correctly. Since its working fine GNOME the drivers are fine. This is sure a KDE specific issue. Other threads related to this on the interwebs don't offer much information either. Please share a solution for this.

• Data, Log and Temp file placement

  - by jchang

  First especially for all the people with SAN storage, drive letters are of no consequence. What matters is the actual physical disk layout. Forget capacity, pay attention to the number of spindles supporting each RAID group. If the RAID group is shared with other application, make sure there the SLA guarantees read and write latency. One very large company conducted a stress test in the QA environment. The SAN admin carved the LUNs from the same pool of disks as production, but thought he had a really...(read more)

• Connecting MS SQL using freetds and unixodbc: isql - no default driver specified

  I am trying to connect to the MS SQL database using freetds and unixodbc. I have read various guides how to do it, but no one works fine for me.

• Dell OpenManage iDrac

  - by mhouston100

  I have installed OpenManage Server Administrator on a Windows 7 workstation with the assumption that nothing needed to be done on the actual server I am trying to manage. The server has an iDrac v7 component and I was under the impression that OpenManage just connects to that? When I try to connect I put the IP address of the iDrac console and the username/password and I get a 'Connection Error' message. So my question, does OpenManage have to be installed on the server that is to be managed, even if it has a DRAC connection?

• maemo - n900 - SIP call quality

  - by Walter White

  Hi all, I have been using SIP / VoIP on my n900 to make calls and my problem is after about 15 minutes of talk time, more recently 18 minutes exactly, my connection dies and I can no longer hear them or them me. I have tested this with various VoIP providers to confirm that it is not specific to any one provider, but instead my phone. I also have tested this on my laptop. I sent my phone to be tested at some place that tests hardware and no problems were found with the hardware. What can I do to rectify the 15 minute call barrier with SIP on my phone? The other problem I have too is that for the wireless broadband to start working again, I need to restart the phone, it appears the network driver gets overloaded. The one thing that appears to work fine is making cellular calls. I have yet to have call quality drop off after 15 minutes over a cellular connection. Thanks, Walter

• tomato firmware unstable when I am connected to Chromecast

  - by Graviton

  I have an Asus RT-N12D1, and I installed the tomato firmware by shibby ( version tomato-K26-1.28.RT-N5x-MIPSR2-112-Max.trx). However I found that the connection can be really unstable. Whenever I stream youtube videos on TV via Chromecast ( I tried both the cast from iPad and Win7, both can reproduce the problem), the router will frequently restart itself, leading to a loss of connection and subsequent reconnection. I want to get this problem fixed, but I don't know how. Is there anyway where I can troubleshoot what is the real problem, or is there anyway I can collect enough log information so that I can then present to the original developer for a fix ( maybe)?

• What FTP clients securely handle FTP/TLS where the server has a self-signed cert?

  - by billpg

  I'm trying to connect to an FTP server that uses TLS on port 990. Unfortunately, the server uses a self-signed cert. What FTP clients for Windows handle this type of connection securely, such that I can securely verify the cert before continuing with the connection and logging in? (The server admin has supplied me with the expected certificate thumbprint to look for.) As an example of doing it wrongly, Core FTP LE 2.2 presents a dialog with basic information about the cert presented, inviting me to accept-once, accept-always or cancel. The dialog does not include the cert's hash/thumbprint and without that thumprint, I can't verify if the cert I'm being presented is the right one.

• Configure SQL Server to Allow Remote Connections

  - by Ben Griswold

  Okay. This post isn’t about configuring SQL to allow remote connections, but wait, I still may be able to help you out. "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 – Could not open a connection to SQL Server)" I love this exception. It summarized the issue and leads you down a path to solving the problem.  I do wish the bit about allowing remote connections was left out of the message though. I can’t think of a time when having remote connections disabled caused me grief.  Heck, I can’t ever remember how to enable remote connections unless I Google for the answer. Anyway, 9 out of 10 times, SQL Server simply isn’t running.  That’s why the exception occurs.  The next time this exception pops up, open up the services console and make sure SQL Server is started.  And if that’s not the problem, only then start digging into the other possible reasons for the failure.

• Logging Timeout'd Request in Apache 2.X

  - by m3rLinEz

  Hello, I am migrating some applications from Apache 1.3 to 2.2. We used to run some tests where attacker opens some HTTP connection to our server, and do nothing. Apache 1.3 would log the following 408 code, for example: 126.1.86.85 - - [01/Dec/2010:06:26:19 +0000] "-" 408 - "-" 0 126.1.86.85 - - [01/Dec/2010:06:26:19 +0000] "-" 408 - "-" 0 But with Apache 2.2, nothing is logged to the log file. I run the same test by using netcat to open the connection: $ nc IP_victim PORT_victim $ nc 10.42.37.3 80 I would like to have Apache 2.2 log the same 408 code to the log file, so that we would know of attempted DoS attack from the outside. Do I need any more configuration in Apache 2 to enable this? I have tried some different configurations such as LogLevel = Debug, Timeout 30, RequestReadTimeout header=10 body=30. Thanks.

• Components needed for a VPN

  - by Anriëtte Combrink

  Hi there, first of all, I asked this question on SuperUser.com, but no one there could help me. Well, we eventually got our Mac Mini Server. We now want to set up a small Remote Access VPN using this Mac Mini Server. Firstly we are not sure of the components needed additionally to the server to setup this VPN. We currently have the following: 1 Mac Mini Server 1 Firewall Router (Billion 802.11g ADSL2+ router with VPN capabilities [it says so on the box]), we currently use this as our internet connection and resides X.X.0.1 on our network. 4Mbps ADSL connection (Should this line have VPN capability enabled by the service provider?) We are not sure what else needs to be included to enable our small VPN. Any advice would be really helpful?

• July, the 31 Days of SQL Server DMO’s – Day 3 (sys.dm_exec_connections)

  - by Tamarick Hill

    The third DMV we will review is the sys.dm_exec_connections DMV. This DMV is Server-Scoped and displays information about each and every current connection on your SQL Server Instance. Lets take a look at some information that this DMV returns. SELECT * FROM sys.dm_exec_connections After reviewing this DMV, in my opinion, its not a whole lot of useful information returned from this DMV from a monitoring or troubleshooting standpoint. The primary use case I have for this DMV is when I need to get a quick count of how many connections I have on one of my SQL Server boxes. For this purpose a quick SELECT COUNT(*) satisfies my need. However, for those who need it, there is other information such as what type of authentication a specific connection is using, network packet size, and client/local TCP ports being used. This information can come in handy for specific scenarios but you probably wont need it very much for your day to day monitoring/troubleshooting needs. However, this is still an important DMV that you should be aware of in the event that you need it. For more information on this DMV, please see the below Books Online link: http://msdn.microsoft.com/en-us/library/ms181509.aspx

• OSX 10.6 Cisco IPSEC strange behavior

  - by tair

  I'm trying to connect to Cisco IPSEC VPN of my company over DSL Internet. I managed to successfully connect using Cisco VPN Client, now I'm trying to switch to OSX 10.6 native client, because of licensing issues. The problems is that the connection fails with a dialog box containing the message: The negotiation with the VPN server failed. Verify the server address and try reconnecting. I checked logs: Jun 29 13:10:39 racoon[4551]: Connecting. Jun 29 13:10:39 racoon[4551]: IKE Packet: transmit success. (Initiator, Aggressive-Mode message 1).

Then I opened Terminal, started pinging a server behind VPN, and tried to connect again. Now connection is OK! Logs this time: Jun 29 13:46:53 racoon[8136]: Connecting.
