• How can I control which IP address IIS7 uses?

  - by brennanwstehling

  In Win2k3 I used httpcfg to tell IIS to listen to specific IP addresses on the server. I want to run Apache with VisualSVN Server on port 80 on another IP address but IIS7 binds to all ports by default. What utility for IIS7 controls the IIS7 bindings? Update: I found the answer. There is a utility called netsh. netsh http add iplisten ipaddress=xxx.xxx.xxx.xxx By default there are not IP addresses on the list so IIS7 will bind to all IP addressed. If you add one IP to the list it will listen to just that IP or any IP added to the list. It is necessary to restart IIS7 for the change to take affect.

• Python version issues

  - by MidnightLightning

  I have a Mac which uses MacPorts to have multiple versions of Python installed and use the python_select application to switch between them. Currently, this Mac has OS 10.6.6, which comes with Python 2.6.1 installed as /usr/bin/python. Using MacPorts, I've installed the python27, python31, and python_select ports and now have this issue: python_select seems to not be switching the default python properly: $ which python /usr/bin/python $ python -V Python 2.6.1 $ /usr/bin/python -V Python 2.6.1 $ sudo python_select python27 Selecting version "python27" for python $ which python /opt/local/bin/python $ ls -l /opt/local/bin/python lrwxr-xr-x 1 root admin 24B Mar 18 10:24 /opt/local/bin/python -> /opt/local/bin/python2.7 $ python -V Python 2.6.1 # <-- Wrong!!! $ /opt/local/bin/python -V Python 2.7.1 # <-- Why are you not default? So, after running python_select, which python seems to think that the /opt/local/bin version is going to be used, but in reality, it seems that the /usr/bin one is taking precedent unless I specifically call the /opt/local/bin one. Is there something I'm doing wrong?

• Cisco VPN Client connects but unable to ping or RDP

  - by bryanroth

  I'm a developer and don't have much networking expertise, so bare with me. I'm using the Cisco VPN Client 5.0.02.0090 to connect to my work's VPN that way I can RDP into my work computer. Once connected, I can't ping anything on the local network once connected to the VPN thus I am unable to access my work's network. This used to work about two weeks ago but abruptly stopped working today. However, I have the Cisco VPN Client installed on my laptop and I am able to ping and RDP into my work computer from there. Both my desktop and laptop computers are connected to the same router at home. I have tried the following so far: Rebooted my computer Reinstalled VPN client Updated NIC drivers Disabled firewall Opened up ports 500, 4500, and 10000 Any help would be much appreciated. Thanks!

• Server with IIS and Apache - how to SSL encrypt Apache with IIS

  - by GAThrawn

  I have a Windows Server 2003 box already setup and working with IIS 6. IIS is set to serve a site out over both HTTP and HTTPS connections using default ports. For various reasons I need to set Apache up on the same server and it needs to serve its pages to end-users as SSL encrypted HTTPS pages. Neither IIS or Apache are (or are ever likely to be) particularly high traffic or high usage. The way I see it there are two possible ways this could be done. Either export the SSL cert from IIS,set it up in Apache and get Apache to server the HTTPS connections itself over a non-default port. Or use IIS to proxy Apache in some way over it's existing SSL security. What is going to end up easiest to setup, configure, maintain and run? Which is going to work best? Has anyone done this sort of thing before? Any tips or things to look out for?

• Standard Protection:Prevent IRC communication

  - by awe

  I have McAffee virusscan on my work computer, and every time I start up, I get 2 log entries like this: Blocked by port blocking rule C:\Program Files\Skype\Phone\Skype.exe Anti-virus Standard Protection:Prevent IRC communication The difference between the two, is that at the end there are 2 different IP addresses (which I don't recognise as belongs to us) with port :6667 on one and :6669 on the other. Although this is logged, Skype seems to work as expected; including talking, chatting and screen sharing (new feature in Skype 4.1). Anyone knows anything about what this is? EDIT: I also have a Skype certified plugin in Skype called Cucku Backup. I did not find anything in the documentation that Cucku is trying to access these ports through Skype, but it could be...? EDIT2: I did a search on the IP addresses in question on www.webyield.net, and resulted in the following: IP 71.251.72.173 (this one used port :6667): Host name: pool-71-251-72-173.tampfl.fios.verizon.net IP 79.87.54.165 (this one used port :6669): Host name: 165.54.87-79.rev.gaoland.net

• Home networking problem between power line communication and Ethernet

  - by pixeline

  My network runs through the electrical wiring of the house and is organised as such: Groundfloor: an ADSL+network switch, using DHCP (address : 172.19.3.1) (Mac) PCs connected via an electrical adapter (model: D-Link DHP-200) (1 per PC) First Floor: 1 switch (8 ports) connected via an electrical adapter (model: D-Link DHP-200) (address unknown) 2 Mac PCs connected (via RJ45 network wires) to that router using DHCP The Problem On the first floor, file tranfers between PCs are fast and perfect. But if I try to transfer files from or to a computer on the ground floor, the speed is slow and eventually the transfer dies out. The Question So I suspect the 1st floor switch is creating some kind of barrier (firewall?) preventing external PCs from accessing the PCs it is connected to? Am I right and if so, how could I disable that barrier?

• ESXI 4 IPMI 2.0 - Cannot connect to IPMI after boot past bios

  - by adamflavell

  Dear All, I would appreciate any help here. I have a Supermicro 6016T-NTRF running ESXI 4 fine. The health monitors are showing up so ESXI is picking up the IPMI status. But I cannot connect to the host remotely via the dedicated IPMI nic. When the machine is in bios section I CAN connect but as soon as ESXI starts to boot I get blocked. Supermicro say the issue must be that ESXI is blocking the IPMI ports. How can this be corrected? I have read that there is no firewall on ESXI 4. Thanks, Adam

• Cisco ASA 5510 ASDM: Setting up multiple public static ip addresses on a single interface and route

  - by ssjaken

  HI, i have a cisco ASA 5510 using ASDM version 6.3 We have a webserver that is been written very specifically and i was given super direct "DO NOT DEVIATE" directions. This server has to get traffic from 3 different PUBLIC ip's that we own. (our isp gave use a block of 12 static addresses) on 4 different ports. there are the directions i was given externalIP1:22 - 172.17.5.50:22 - SSH externalIP1:443 - 172.17.5.50:23040 - SIT externalIP2:443 - 172.17.5.50:33040 - STAGE externalIP3:443 - 172.17.5.50:43040 - PROD My first question is, using ASDM (my contract employer demands i use ASDM over CLI) how do i get three public addresses to work on one interface. We are authenticating on PPPoE. I know create a virtual interface with the static address but when i do i cannot ping the address from another offsite machine. secondly, where would i put the traffic redirect in. would i go ahead and create ACL's or just make NAT routes. Thanks.

• Forward local port or socket file to remote socket file

  - by Ninefingers

  Hi All, Quick question - I run two linux boxes, one my own desktop and the other my VPS. For security reasons on the VPS end I opted for socket connections to MySQL (/var/run/mysqld/mysql.sock). I know I can tunnel like this: ssh -L 3307:127.0.0.1:3306 [email protected] if I set up the remote sql server to listen on some port, but what I want to know is can I do something like: ssh -L /path/to/myremotesqlserver.sock:/var/run/mysqld/mysql.sock thereby tunnelling two sockets, as opposed to two ports? A perfectly acceptable solution would also be to forward a local port to the remote socket file, but where possible I'm trying not to have tcp servers running on the remote box. (and yes, I know tcp would be easier). Thanks all, Nf.

• Memory Pressure Protection Feature for TCP Stack - Provided by Microsoft Security Update KB967723

  - by Angry_IT_Guru

  We've been having a lot of funky issues with some of our web based applications that allow clients to submit lot of image files to our servers. Lots of ports are used in the process. http://www.microsoft.com/technet/security/bulletin/MS09-048.mspx - released in Sept-2009. support.microsoft.com/kb/974288 - Memory Pressure Protection description. Evidently, after applying KB967723, our clients receive funky error messages as if connections cannot be made to the server or connections have been closed. There doesn't appear to be a pattern and sometimes it works and other times is doesn't. Typically we've noticed it when server is under load. I'm curious what others think about this MPP and any issues that you may have experienced from it. I understand its purpose, but I think it may have broken a lot of apps in the process. It doesn't look like Microsoft made this "feature" public to everyone.

• Cisco ASA Hairpinning with Dynamic IP

  - by Joseph Sturtevant

  I currently have my Cisco ASA 5505 firewall configured to forward port 80 from the outside interface to a host on my dmz interface. I also need to allow clients on my inside interface to access the host in the dmz by entering the public ip / dns record in their browsers. I was able to do that by following the instructions here, resulting in the following configuration: static (dmz,outside) tcp interface www 192.168.1.5 www netmask 255.255.255.255 static (dmz,inside) tcp 74.125.45.100 www 192.168.1.5 www netmask 255.255.255.255 (Where 74.125.45.100 is my public IP and 192.168.1.5 is the IP of the dmz host) This works great except for the fact that my network has a dynamic public IP and this configuration will therefore break as soon as my public IP changes. Is there a way to do what I want with a dynamic ip? Note: Adding an internal DNS record won't solve my problem since I have multiple dmz hosts mapped to different ports on the public IP.

• pfSense with two WANs, routing skype traffic over a specific WAN

  - by Eric

  I have a pfSense setup with two WANs (WAN1 and WAN2) and one LAN network. The two WANs are setup for failover. However, QoS has recently been an issue for skype calls in our office place (about 30 people) so we want to dedicate WAN2 for skype traffic (we use skype for all voip calls, etc.) As Skype is notoriously difficult to deal with, does anyone have any suggestions on how I should deal with this? A simple rile based on ports will not work, and using layer7 inspection witha skype porfile on all incoming LAN packets doesn't seem like the way to go eiter. here is a related pfsense forum post: http://forum.pfsense.org/index.php/topic,50406.msg268520.html#msg268520

• How to charge an iPhone on a Windows PC without Installing iTunes

  - by Martin Hollingsworth

  I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

• Recommended ADSL/ADSL2 router that supports PPTP VPN dial-out, 802.11n and gigabit ethernet?

  - by Throlkim

  I'm looking for a new router to provide a VPN tunnel for my home network. My plan is to pass all internet traffic over a PPTP VPN provided by the router, which should ensure that the connection stays alive and only passes traffic over that protocol. I'm normally quite a fan of Draytek routers, and their 2710n does seem to feature VPN dial-out but it lacks Gigabit ports (though I can make do with that if the VPN support is good enough). Has anyone got any suggestions or personal experience in a similar setup? I'm happy to consider anything that supports dd-wrt (as I believe that supports VPN-out, though I may be wrong). Bonus points for models available in the UK.

• DD-WRT Router acting as a Switch and Wi-Fi AP

  - by dotnetchris

  Recently I upgraded to Comcast Business and their modem has a built-in router so I took off my DD-WRT router and moved to a location in my home where I needed more ports and Wi-Fi (preferably without running new Ethernet cables since it's 50-100 foot run through floor and ceilings). I have my network cable from my Comcast modem going into Port 1 of my DD-WRT router with Port 2 and 3 being networked PCs. I have DD-WRT setup as a DHCP forwarder with the firewall disabled. This lets my all of my devices access the network fine. Is the correct the way to do this? Or is this a less optimal solution and it should be done in a slightly different way?

• What would be the optimal disk config for SQL Server 2008 R2?

  - by Kev

  We have a new Dell R710 server that came with the following storage configuration: 8 x 146GB SAS 10k 6Gbps disks 1 x Perc H700 Integrated Controller (2 x 4 disks - 2 ports each supporting 4 disks) What would be the optimal configuration if we were just after performance? What would be the optimal configuration if we were after performance but wanted data resilience. As per 2 above but with a hot standby disk? We plan to run Windows 2008 R2 and SQL Server 2008 R2. Maximising storage capacity isn't a prime concern.

• setup Zyxel USG 20W as L2TP VPN Server

  - by Massimo

  I've a Zywall USG 20W (wireless disabled) behind a router supplied by the ISP. All ports (both TCP and UDP) on the ISP router are forwarded to the 20W. I'm trying to configure an L2TP VPN to be used by Windows Xp / 7 with Microsoft native client. This was working before with a different firewall, so I'm pretty sure that all the required packets are flowing to the 20W. I followed a tutorial from the italian Zyxel Website, but I cannot get the VPN to work. Always cannot pass phase 2, and I see the following on the log: [ID]: Tunnel [Default_L2TP_VPN_Connection] Phase 2 local policy mismatch Phase 1 goes fine. In Windows the error is always 788. This happens regardless the proposals I set in the phase 1 and 2 setting. What should I check ? Is there any way to get more detailed diagnostic info (policy mismatch is too generic) ? Thanks a lot to whom may help. Massimo.

• Airport Extreme roaming setup

  - by Daniel Johansson

  We've got three Apple AirPort extremes and want to setup them as a roaming wlan network on my company. My question is what's the correct setup for this? All three AP:s is supposed to create the same wireless network "MyWlan" and we want roaming supoprt between them so that client can move from floor to floor without having to switch wlan or reconnect. We don't want to use any kind of DHCP or NAT on the AirPorts, only bridge mode. Do we connect the AirPorts to the lan/ethernet using the WAN port or one of the LAN ports? What's the correct settings in the config utility? Have one of the AirPorts create a network and setup the other two to extend the created network from AirPort 1 or have them all create the same network and set the same wlan password?

• dns service on OS X Snow Leopard Server

  - by Sorin Buturugeanu

  Hello all, I have a Mac Mini (1.83GHz, 1.5 RAM) with a fresh install of OS X Snow Leopard Server and I want to use it for DNS and web hosting. What I have done so far is to go to the domain registrar and configure a new nameserver (ns.domain.tld) to point to my static IP. This Mac Mini is behind a DI-524 router and I have forwarded ports 53 and 80 to the Mini. I have also added the domain name to the DNS configuration pannel (as in the attachment), but intodns.com gives the following error (among others, and obviously the site is not working): "Mismatched NS records WARNING: One or more of your nameservers did not return any of your NS records." I don't know where to go from here .. Thank you to anyone willing to take the time to give me a hint!! seems that I can't post images but here's the link: http://i.imgur.com/zWI7Y.png

• Create firewall "profiles" for Windows 7

  - by Samantha

  Is there any way to configure a couple of firewall profiles in Windows 7? As I use mobile broadband on when traveling, I don't want virus scanner/windows updates etc running and chewing up my mobile data allocation. So would love to find a way to block everything except email ports and perhaps http. The kicker though is that when I'm back in the office, I want to just click a button to get my original firewall settings back. In the office I use WiFi and on the road tether to my android phone, also via WiFi, so can't restrict via network interface. Any ideas?

• ReadyNAS Duo - FTP home network connectivity issue

  - by dwabyick

  I have a ReadyNas Duo that I recently purchased and configured on my local home network. I'm an AT&T DSL subscriber using their default 2701HG-B Gateway (2Wire) wireless router. Basically, I have managed to configure my ReadyNAS, and can access HTTP shares and WINS shares just fine, but cannot get access to it via FTP. I've enabled it in the 'Standard File Protocols' section in the UI, and made a share have read/write default access via FTP. My settings: Port: 21 Authentication mode: User Allow upload resumes: Yes Passive ports: 1024-65535 Masquerade as: (empty, but I've tried the internal IP address). I've even poked around at my router, which has a firewall, and even tried to poke a hole for the 'FTP Server'app for the ReadyNAS. Doesn't seem like I should need to do this, or should. Any ideas what else to check? Thanks! -Daniel
