  • Accessing guests on virtual network when connected to host via PPTP

    - by Viktor Elofsson
    I'm setting up a development machine which runs Ubuntu 12.04 and KVM for virtualization. I have a guest running Ubuntu 12.04 which can be accessed from the host via its IP address which is assigned by libvirt. The guest can also access the internet, no problem there. However, now I want to setup PPTP so I can connect to the host (from my workstation running Windows 7) and directly access guests without relying on SSH port forwarding. I can connect from my W7-machine to the host (PPTP), but I cannot access any virtual machines (which are accessable from the host directly). Relevant configuration files cat /etc/network/interfaces auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address x.x.x.x broadcast x.x.x.x netmask x.x.x.x gateway x.x.x.x # default route to access subnet up route add -net x.x.x.x netmask x.x.x.x gw x.x.x.x eth0 virsh net-edit default <network> <name>default</name> <uuid>xxxxxxxx-72ce-3c20-af0f-d3a010f1bef0</uuid> <forward mode='nat'/> <bridge name='virbr0' stp='on' delay='0' /> <mac address='52:54:00:xx:xx:xx'/> <ip address='192.168.122.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.122.2' end='192.168.122.254' /> <host mac='52:54:00:yy:yy:yy' name='web1' ip='192.168.122.11' /> </dhcp> </ip> </network> cat /etc/pptpd.conf (commented lines removed) # TAG: option # Specifies the location of the PPP options file. # By default PPP looks in '/etc/ppp/options' # option /etc/ppp/pptpd-options # TAG: logwtmp # Use wtmp(5) to record client connections and disconnections. # logwtmp #(Recommended) localip 192.168.122.1 remoteip 192.168.122.234-238,192.168.122.245 cat /etc/ppp/chap-secrets* # Secrets for authentication using CHAP # client server secret IP addresses xxxxx * yyyyyyyyyy 192.168.122.100 I get the correct IP address when connecting my W7-machine, but when I try to ping the virtual machine at 192.168.122.11 I get Reply from 192.168.122.1: Destination port unreachable. It's probably something trivial I'm missing but I can't for the life of me figure out what it is. So I'm turning to you, serverfault.

  • Access Router after logging into VPN

    - by Dan
    I access my linksys router through its webserver (192.168.1.1 into a web browser), but can no longer access it once I log into my work vpn. Is there a way I can still get at my router and change the settings? Or do I first have to disconnect from the VPN first? Thanks, Dan

    - by mactruck

What IIS settings should I look at?

  • Links not using FQDN on Sharepoint Mysite from an external access

    - by Busted Keaton
    Hello all I've configured external access to some sharepoint applications, including MySites, using AAM and ISA configuration. Every seems working well, but when using the external access (ie via https), some links are not working because they use the internal name (http://mysite) instead of the FQDN via https (https://mysite.mydomain.fr*) Any hint or suggestion are welcome. *yes, i'm french. =) EDIT : examples of links that are not working : - when clicking on a folder in a library - when clicking on "My links" then "My sharepoint sites" and then clicking on one of the links displayed

  • Wine and Kernel Access

    - by Kyle Rozendo
    My knowledge on the topic is rather limited, but does one have Kernel access/the general ability to change programs at run time whilst running Wine? For Clarification: Can the user of the computer access any information they want via the Kernel on the underlying system running Wine, or does normal Windows security still apply?

  • Multiple access points for the same SSID ?

    - by krosenvold
    I need to upgrade my existing wireless infrastructure and this time I want 2 access points to cover my house, since I get blind spots no matter what with a single AP, I have physical cabling to my central network available for both access points. But I would really like these two to interoperate seamlessly as a single SSID. How do I do this and what are the features the new AP's I'm buying need to support ? (Product recommendations are welcome ;)

  • Networking Mac and PC - Firewall Issue?

    - by zm15
    Here's the scenario: Work network - I have a Mac and a PC - OS X is Snow Leopard - Windows 7 I am trying to connect to the PC from the Mac. IT ONLY works if I turn off the firewall in Windows. I tried to trace the port and connection it was using, it appears to be on port 445 via TCP. I really prefer not to leave this open, or is it OK? How can I only allow this connection while still leaving the firewall on?

  • SQL CE not loading from network share

    - by David Veeneman
    I installed VS 2010 RC yesterday, and suddenly, SQL Server CE isn't loading files from a network share. In projects compiled with VS 2008, if I try to open a SQL CE file located on a network share, I get an error that reads like this: Internal error: Cannot open the shared memory region. If I try to create a data connection in VS 2010 to a SQL CE file on a network share, I get this error: SQL Server Compact does not support opening database files on a network share. Can anyone shed any light on what's going on? Thanks.

  • My facebook blocking ACL has stopped working

    - by Josh
    This probably very simple. This was setup before I arrived, and has been working to block facebook. I recently eliminated some static port forwarding on this 2691 (as in, I don't think anything else has changed), and now facebook is once again accessible. Why is this list not doing what it seems like it should be doing (and was doing)? Would an extended outbound ACL be more appropriate (I think that would have been my thought if I had been tasked with creating this in the first place)? Something different? I've included below what I believe are the relevant parts of the config. interface FastEthernet0/0 ip address my.pub.ip.add my.ip.add.msk ip access-group 1 in ip nat outside ip virtual-reassembly duplex auto speed auto access-list 1 deny 69.171.224.0 0.0.31.255 access-list 1 deny 74.119.76.0 0.0.3.255 access-list 1 deny 204.15.20.0 0.0.3.255 access-list 1 deny 66.220.144.0 0.0.15.255 access-list 1 deny 69.63.176.0 0.0.15.255 access-list 1 permit any ip nat inside source list 105 interface FastEthernet0/0 overload access-list 105 deny ip 192.168.0.0 0.0.0.255 192.168.8.0 0.0.0.255 access-list 105 permit ip 192.168.0.0 0.0.0.255 any access-list 105 permit ip 192.168.1.0 0.0.0.255 any EDIT ACL is once again blocking Facebook. Here is the new definition for those interested... access-list 1 deny 66.220.144.0 0.0.7.255 access-list 1 deny 66.220.152.0 0.0.7.255 access-list 1 deny 69.63.176.0 0.0.7.255 access-list 1 deny 69.63.176.0 0.0.0.255 access-list 1 deny 69.63.184.0 0.0.7.255 access-list 1 deny 69.171.224.0 0.0.15.255 access-list 1 deny 69.171.239.0 0.0.0.255 access-list 1 deny 69.171.240.0 0.0.15.255 access-list 1 deny 69.171.255.0 0.0.0.255 access-list 1 deny 74.119.76.0 0.0.3.255 access-list 1 deny 173.252.64.0 0.0.31.255 access-list 1 deny 173.252.70.0 0.0.0.255 access-list 1 deny 173.252.96.0 0.0.31.255 access-list 1 deny 204.15.20.0 0.0.3.255 access-list 1 permit any

  • Wireless Network Disappearing From Available Networks (Windows 7)

    - by PeteDaMeat
    I have been using Windows 7 with a BT Voyager wireless adapter to connect to my home wireless network for around the last 6 months or so and until recently have experienced no problems. However, over the last couple of days Windows has been unable to connect to the network and the network name is no longer visible in the list of available wireless networks. The only way I have got round the problem is to reboot the NetGear router and to change the SSID to a network name which has not already been used. I do not believe the problem is with the router as my mobile phone can connect to it without any problems. The BT Voyager wireless adapter detects all other available networks so I presume this is a Windows 7 issue as it seems to occur when the PC is rebooted. This problen has happened twice in the last 2 days and is becoming extremely annoying. Does anyone have any suggestions?

  • LocalUser access for WCF hosted in IIS

    - by Eugarps
    I have tried every combination to allow unauthenticated access to WCF as in "LocalUser" accounts, in IIS without success. Here is what I've most recently tried: wsHttpBinding with Message security and mode set to "None". IIS anonymous access enabled, all others disabled, folder level access at default (but granted read access to "Users" which is all users in our domain). I understand I may not have provided enough information to solve the issue, but perhaps somebody can point me in the right direction - is this likely to be a IIS configuration issue or a WCF configuration issue... if WCF, is it likely to be a client level or server level issue? The error I get when attempting to access here is "User is not authenticated". We have ASMX services in the domain which are behaving properly, I am the first developer using WCF here.

  • Unable to add IPv6 address to sendmail access list

    - by David M. Syzdek
    I am running Sendmail 8.14.4 on Slackware 13.37. I have the following in my /etc/mail/access file and it works without any errors: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite The above configuration also allows me to send an e-mail via IPv6 to a local user on the mail server. However, it does not allow my office to relay via IPv6. I have tried two ways of adding IPv6 networks to my access file. Method 1: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:IPv6:2001:470:b:84a RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite Method 2: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:[IPv6:2001:470:b:84a] RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite However whenever I try using either method 1 or 2, I am unable to relay e-mail messages through the host. /var/log/maillog entry: May 31 11:57:15 freshsalmon sm-mta[25500]: ruleset=check_relay, arg1=[IPv6:2001:470:b:84a:223:6cff:fe80:35dc], arg2=IPv6:2001:470:b:84a:223:6cff:fe80:35dc, relay=[IPv6:2001:470:b:84a:223:6cff:fe80:35dc], reject=553 5.3.0 RELAY # Net:office Test session from telnet: syzdek@blackenhawk$ telnet -6 freshsalmon.office.example.com 25 Trying 2001:470:b:84a::69...

  • Certain Programs cannot access internet

    - by Cindy
    Operating System: Windows 7 (x64) Problem: Certain Programs are unable to access the internet. They claim that there is no connection when you already are connected. Hello, before we start. Just letting you know I'm new here, and I'm very new to Windows 7. I installed it two days ago. I just installed Windows 7 on my laptop and I have a few problems. I play World of Warcraft, as well as a variety of games. And when I first attempt to log into the game, I get a windows error message, but it doesn't stop there. I thought World of Warcraft got corrupted during the upgrade. It seems that I am unable to access the internet from other online games as well. Most say in along the lines of "Cannot connect to patch server, try again later." I cannot use a downloader Also, I have internet explorer. The x32 version of the browser cannot connect to the internet, and when I try to enter "google.com", it says the same thing. I'm only accessing this site through Internet Explorer x64, which I would have been fine with is it's compatible with Adobe Flash. The only thing that seems to connect to the internet are Internet Explorer x64 and Windows Live Messenger. Here are the steps I have taken, but none worked. 1.) Disable Windows Firewall 2.) Have Windows Firewall Enabled, but allow the specific programs to access internet. And allowed all incoming access. 3.) Disabled UAC, Ran the programs as an admin, and set compatibility to Vista. 4.) Uninstalled an anti-virus program. (McAffee Security Suite 2010) 5.) Reinstalled the programs 6.) Reinstalled Windows 7 7.) Retaken the steps on the Administrator account. Please assist me in this problem. I need to get back into the game. Thanks so much in advance.

  • Autotesting a network interface

    - by Machado
    Hi All, I'm developing a software component responsible for testing if a network interface has conectivity with the internet. Think of it as the same test the XBOX360 does to inform the user if it's connected with the Live network (just as an example). So far I figured the autotest would run as this: 1) Test the physical network interface (if the cable is conected, has up/downlink, etc...) 2) Test the logical network (has IP address, has DNS, etc...) 3) Connects to the internet (can access google, for example) 4) ??? 5) Profit! (just kidding...) My question relates to step 3: How can I detect, correctly, if my software has connection with the internet ? Is there any fixed IP address to ping ? The problem is that I don't want to rely solely on google.com (or any other well-known address), as those can change in time, and my component will be embbeded on a mobile device, not easy to update. Any suggestions ?
