  • unable to access a NAT'ed IP via a VPN on Windows 7

    - by crmpicco
    I connect to a range of servers hosted by one provider via a VPN. I can connect to the VPN fine, however when I then go and try and connect to the server(s) it fails. A NAT'ed IP address that has worked up until today, has stopped working either via SSH/SFTP. As you can see below, if I try and ping the IP then it responds with Destination host unreachable, but, for some reason it says the reply is from 192.168.0.8? If it enter this IP address in my browser, I get nothing. Where is this IP coming from and is there any good reason why I cannot access the IP I am trying to ping? C:\Users\crmpicco>ping 172.26.100.x Pinging 172.26.100.x with 32 bytes of data: Reply from 192.168.0.8: Destination host unreachable. Reply from 192.168.0.8: Destination host unreachable.

But i'm unsure if there is a config issue at the server side or my end that has caused this issue? I have had some recent Win7 (automatic) updates, but it's hard to tell if that's caused this problem.

    We have setup ipsec and l2tp on linux. One question came up (due to firewall management policy) is whether it's possible to have 1 virtual interface instead of one per connected client. Now we have: ppp0 serverip clientip1 ppp1 serverip clientip2 Want to have: l2tp_tun serverip serverip like with OpenVPN's tun interfaces and then to be able to push IP address and route to each client.

  • How to edit a table in the email reply (in Gmail)?

    - by imz
    I've received an email with an embedded table. I want to put some marks inside that table (i.e., edit the contentof the table) and send it back. Unfortunately, the Gmail interface doesn't seem to have table editing capabilities: after I hit reply, I see the table in the quoted text of the original message, but is not editable... If this is not possible in Gmail, how do I export the HTML source of this messsage and edit in another installed word processor?

  • Primary/secondary ethernet interfaces via NetworkManager in Ubuntu 9.10

    - by Josh
    I have an Ubuntu 9.10 machine with three ethernet interfaces, eth0, eth1 and eth2. eth2 is connected to a private network. eth0 and eth2 are connected to two different LANs. Either one will provide access to the internet. All three networks have DHCP servers. Using Ubuntu's the default settings (And Gnome), when I boot up all the interfaces are active and my system gets three IP addresses. However any attempt to access the internet results in connection timeouts and other weirdness. I suspect that traffic is going out on one NIC (like eth0) and coming back in on another (like eth1). I'm not sure what's going on. The only way I can access the internet at the moment is to bring two of the devices down with ifdown. How can I configure eth0 as my primary interface so all trafic goes out by default on that interface, while keeping the other two active? Also, I want to make sure Avahi broadcasts properly on all three IPs so that the computers on the LAN of eth1 can still connect to myHostname.local... EDIT: Here's my routing table: Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 172.16.151.0 0.0.0.0 255.255.255.0 U 0 0 0 eth2 172.16.30.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.1.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 172.16.30.2 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 10.1.0.1 0.0.0.0 UG 0 0 0 eth1 I want the 172.16.30.2 network to be the primary one and the 10.1.0.0 network to be the secondary one. EDIT2: My nameservers are also incorrect. It seems like Ubuntu is bringing the networks up in order, eth0, then 1, then 2, and the DHCP information from eth1 is overriding eth0, and eth2 is overriding eth1. How can I reverse this so the DHCP information from eth0 is the "master"? EDIT3: This seems to be an issue with Gnome's NetworkManager.

    I have a Lenovo 3000 N200 notebook with integrated GMA 965 VGA, using Windows 7. All my drivers are up to date, downloaded directly from the vendor site, installed with administrative privileges, etc. Yet, all OpenGL applications cannot render the interface (or any visuals). Examples are Blender (3D modeling software) and Babo Violent (top-down FPS). All the controls, sound effects and music are live, but the screen is black or light gray, respectively. What can one do?

  • How can I change the apache config for a virtual host, from the shell on a whm/cpanel system?

    - by Chiggsy
    I wanted to change the setting for a virtual host in a hurry I knew how to "just do it" but I'm not very familiar with the restrictions of the cpanel system. I read the theory of the config system and regardless of my feelings on the matter I understand where they are coming from. However in that world view, there must be a way to interact with the system from a command line interface, not just for httpd.conf but for the virtual host containers as well EDIT: reworded this question a bit to show I was talking about a virtual host container.

  • Ubuntu hardware wireless switch has no effect after suspend and 13.10 upgrade

    - by blaineh
    I'm posting this on SU after it stalled on askubuntu. I hope someone here can help! If you'd prefer to answer on AU itself, here's the link: http://askubuntu.com/questions/365177/hardware-wireless-switch-has-no-effect-after-suspend-and-13-10-upgrade Wireless works fine after a reboot, but after a suspend the hardware switch (for my laptop this is f12) has no effect on the wireless, it is just permanently off, and shows that it is with a red LED. My rfkill list all reads: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes Any combination with rfkill <un>block wifi doesn't work, although one time first blocking then unblocking actually turned it on again. sudo lshw -C network reads: *-network DISABLED description: Wireless interface product: AR9285 Wireless Network Adapter (PCI-Express) vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlan0 version: 01 serial: 78:e4:00:65:2e:3f width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath9k driverversion=3.11.0-12-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:90100000-9010ffff *-network DISABLED description: Ethernet interface product: RTL8101E/RTL8102E PCI Express Fast Ethernet controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:03:00.0 logical name: eth0 version: 02 serial: c8:0a:a9:89:b4:30 size: 10Mbit/s capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list rom ethernet physical tp mii 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8169 driverversion=2.3LK-NAPI duplex=half latency=0 link=no multicast=yes port=MII speed=10Mbit/s resources: irq:42 ioport:2000(size=256) memory:90010000-90010fff memory:90000000-9000ffff memory:90020000-9002ffff Also, adding a /etc/pm/sleep.d/brcm.sh file as recommended here simply prevents the laptop from suspending at all, which of course is no good. This question has an answer urging to install the original driver, but it wasn't an "accepted answer" so I'd rather not take a chance on it. Also I'll admit I'm a bit lost on that and would like help doing so with the specific information I've given. I would be happy to provide more information, so long as you're willing to help me find it for you! This is a very annoying bug. I have a Compaq Presario CQ62. Edit. Output of lspci | grep Network: 02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01) Edit. This morning, I had had the laptop suspended all night, and then when I tried to awake it, it simply wouldn't. It would try, and then it would sleep again (I guess it felt a little bit like me! </badjoke>). Is it possible these problems are related? Edit. I don't have enough reputation on SU proper to post links to pastebins and other questions I've tried, so I'm putting them in comments, and of course they're available in the original question.

  • Any way to map WebDAV with SSL as network drive in Windows XP?

    - by Shadow
    I'm trying to map WebDAV with SSL as a network drive in Windows XP. (I've been at this for several hours) I can read the share just fine using a browser and with Network Places, but it refuses to mount as a network drive. I've tried it using the Windows explorer interface and net use. Net use with the \\server@ssl:443\webdav method gives System error 53. https://server/webdav gives error 67. Any help would be appreciated.

  • Routing table with two NIC adapters in libvirt/KVM

    - by lzap
    I created a virtual NAT network (192.168.100.0/24 network) in my libvirt and new guest with two interfaces - one in this network, one as bridged (10.34.1.0/24 network) to the local LAN. The reason for that is I need to have my own virtual network for my DHCP/TFTP/DNS testing and still want to access my guest externally from my LAN. On both networks I have working DHCP, both giving them IP addresses. When I setup NAT port forwarding (e.g. for ssh), I can connect to the eth0 (virtual network), everything is fine. But when I try to access the eth1 via bridged interface, I have no response. I guess I have problem with my routing table - outgoing packets are routed to the virtual NAT network (which has access to the machine I am connecting from - I can ping it). But I am not sure if this setup is correct. I think I need to add something to my routing table. # ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:B4:A7:5F inet addr:192.168.100.14 Bcast:192.168.100.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:feb4:a75f/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:16468 errors:0 dropped:27 overruns:0 frame:0 TX packets:6081 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:22066140 (21.0 MiB) TX bytes:483249 (471.9 KiB) Interrupt:11 Base address:0x2000 eth1 Link encap:Ethernet HWaddr 52:54:00:DE:16:21 inet addr:10.34.1.111 Bcast:10.34.1.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fede:1621/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:34 errors:0 dropped:0 overruns:0 frame:0 TX packets:189 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:4911 (4.7 KiB) TX bytes:9 # route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.100.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 10.34.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 1002 0 0 eth0 169.254.0.0 0.0.0.0 255.255.0.0 U 1003 0 0 eth1 0.0.0.0 192.168.100.1 0.0.0.0 UG 0 0 0 eth0 Network I am trying to connect from is different than network the hypervisor is connected to: 10.36.0.0. But it is accessible from that network. So I tried to add new route rule: route add -net 10.36.0.0 netmask 255.255.0.0 dev eth1 And it is not working. I thought setting correct interface would be sufficient. What is needed to get my packets coming through?

  • Virtualbox - routing subnet to bridge adapters

    - by user42384
    Hello, I have set up a Debian Lenny box with 3 vbox Lenny machines running eth0 of the host in bridged mode (on virtualbox 3.1.6). When testing in my local LAN, this all worked perfectly well and traffic flowed to and from the IPs of the virtual machines as it should. However, now that it's in its co-lo home, the networking setup is a bit different, and I'm unable to get traffic to flow to the vboxes properly. Specifically, the host has its own Primary IP, and I have a separate subnet of 8 (6 usable) IPs routed to the box for use by the vboxes. So, eth0 on host is: Machine IP: 2x.x.x.137 Gateway IP: 2x.x.x.138 Subnet Msk: 255.255.255.252 Subnet for vboxes is Subnet: 2x.x.x.240/29 Netmask: 255.255.255.248 vbox1 is configured to 2x.x.x.241 on eth0 as follows: auto eth0 iface eth0 inet static address 2x.x.x.241 netmask 255.255.255.248 Setting up a virtual interface (eth0:0) on the host with one of these subnet IPs allows me to ping to that address only from vbox1, and it allows me to ping vbox1 from the host. I can also ping that virtual interface perfectly well from outside, so the IPs are definitely landing at my machine. It seems I'm missing some sort of routing instruction either on the host or vbox1 to get traffic moving between the subnet and the default gateway, but I can't seem to figure out what it should be, or what glaringly obvious thing i'm missing. Most of my obvious attempts (the gw of eth0, the ip of eth0) were rejected by route command with SIOCADDRT: No such device (eg - i can't find it). I tried setting vbox1 to bridge on eth0:0, but this was not an acceptable device name and VBoxHeadless refused to start. The physical machine does have an unused physical NIC at eth1 that can be used if necessary for something or other. Host machine is running iptables configured by ferm, have experimented with it allowing forwarding for that subnet, but I wouldn't have thought this was necessary given the nature of the virtualbox devices (nor did it actually work). Clearing out all of these rules for a blank iptables set does not resolve the issue. (you can see ferm generated iptables at http://codedumper.com/ojaze) Thanks for any help you can give... Patrick

  • Suggestion for software to control internet

    - by redknight
    I need to implement a gateway that will allow me to control the access to the internet of a network made up of a about half a dozen of workstations. My main obejectives are the following: 1- Monitoring of traffic 2- Logging of traffic 3- Access control - block websites (mainly adult) and certian traffic(example torrents) 4- Possibly cache content 5- Easy management interface 6- Preferable free and opensource Serverfault users can you please suggest from your vast experience which software you think is the best to suit my needs? Any suggestion is greatly appreciated. Thank you

  • Multiple virtual VLAN interfaces on single NIC (Debian)

    - by RayQuang
    I'm trying to setup multiple virtual interfaces with VLAN's on a single NIC. I'm running Debian Squeeze. Currently this is my /etc/netowrk/interfaces auto eth0.10 iface eth0.10 inet dhcp This gives me a working connection, however I'm not sure how to configure several like these on a single NIC so I can use multiple external IP's. I have tried aliasing the VLAN's like so: iface eth0.10:1 But that was not successful and it said failed to bring up interface. And suggestions would be greatly appreciated :)

  • Release/Renew IP Address via Terminal in OS X

    - by Rupert
    I am looking to release and renew my IP address in OS X 10.4 using Terminal. Essentially, I need the OS X equivalent of Windows: C:\ ipconfig /release C:\ ipconfig /renew However, I need the interface to remain active during this process, so using ifconfig down/up will not work. I believe I can clear the IP with ifconfig delete but I'm not sure how to get the dhcp client to reassign the address. An article from 2002 suggests using set dhcp but Apple's ifconfig man page does not include this information.
