• setting up bridged adapter for VPN server

  - by B. VB.

  I have an Ubuntu linux Linode server that I am trying to install OpenVPN on. I'm following the tutorials (which, it turns out, are quite incomplete). auto br0 iface br0 inet static address 192.168.0.10 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.1 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off When I add this chunk in my /etc/network/interfaces, and I restart networking, my eth0 interface does not have an IP and I cannot get on the network (I need to use a buggy, slow, and annoying AJAX term to do damage repair). Why does adding this screw everything up? Any tips on how to set up this bridged adapter?? Thanks in advance!

• Ubuntu 12.04 host lookups extremely slow

  - by tubaguy50035

  I'm having issues with one of my servers taking a long time to look up host names. This is an Ubuntu 12.04 box, so I've tried following the new resolvconf directives. In my /etc/network/interfaces file, I defined my name servers like this: auto eth0 iface eth0 inet static address someaddress netmask 255.255.255.0 gateway 198.58.103.1 dns-nameservers 74.14.179.5 72.14.188.5 In my /etc/resolv.conf, I see these name servers, like this: # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 74.14.179.5 nameserver 72.14.188.5 On another box, I edited the resolv.conf directly as directed by my hosts' setup help files. It looks like this: domain members.linode.com search members.linode.com nameserver 72.14.179.5 nameserver 72.14.188.5 options rotate This second box has no issues with host name look ups and responds quite quickly. Could not having the domain and search directives make my look ups slow? By slow, I mean it's taking anywhere from 5 to 15 seconds to find the IP address of a host.

• Cisco ASA - Unable to create "range" type of network object on 8.2

  - by j2k4j

  I'm wanting to block a range of ip addresses on my Cisco ASA 5520 (8.2) using ASDM 6.4. In the help files/cisco documentation, it says, just create a network object with a "range" type, and use that in a blocking access rule... When I'm accessing the ASA (8.2) with ASDM 6.4, I go to configfirewallobjectnetwork objects & groups, then click "add" to add the IP range as a "network object", I get the following 4 fields to fill out: Name: IP address: Netmask: Description: That's all... In the context-sensitive help files, it says that there should be a Type drop-down to select, with "range" being one of the options, but there is no "Type" drop-down list... If I try to create a "network object group" instead of just "network object", then I get a "Type" drop down list, but it only contains two options: network & host (No "Range" option here either) Can someone help me figure out how to block a range of IP's, using the current 8.2 version on the ASA? Thanks for any pointers or tips!

• Connecting/Adding a private network on windows server 2008

  - by WhyMe

  Hey all, I have a dual server configuration on a host provider using VPS. I was told by my Host provider that in order to use free bandwidth between my two servers (they are in the same location) I need to add a alias "subnet" to a specific ip (A private network, VPN). How do I add an aliased ip in widnwos? in Linux the relevant command is supposed to be (By my search in blogs) "ifconfig eth0:1 10.129.175.165 netmask 255.255.255.0" They also said that another way to connect between the servers (should also be faster) is to use "private lan", but as it happens I don't know how to define one :(. Is there a windows equivalent or another way to do this? I have checked my ip config and found no indication of the private lan or the VPN ip.

• Configuring Linux Network

  - by Reiler

  Hi I'm working on some software, that runs on a Centos 5.xx installation. I'ts not allowed for our customers to log in to Linux, everything is done from Windows applications, developed by us. So we have build a frontend for the user to configure network setup: Static/DHCP, ip-address, gateway, DNS, Hostname. Right now I let the user enter the information in the Windows app, and then write it on the Linux server like this: Write to /etc/resolv.conf: Nameserver Write to /etc/sysconfig/network: Gateway and Hostname Write to /etc/sysconfig/network-scripts/ifcfg-eth0: Ipaddress, Netmask, Bootproto(DHCP or Static) I also (after some time) found out that I was unable to send mail, unless I wrote in /etc/hosts: 127.0.0.1 Hostname All this seems to work, but is there a better/easier way to do this? Also, I read the network configuration nearly the same way, but if I use DHCP, I miss som information, for instance the Ip-address. I know that I can get some information from the commandline (ifconfig), but I dont get for instance Hostname, Gateway and DNS. Is there a commandline tool that will display this?

• OpenVPN Configuration - Windows 7 client & debian server

  - by Guillaume

  I recently formatted my Windows 7 computer and lost my client's config files for OpenVPN. I recovered the certificates and default config that were left on the server but I haven't managed to make the whole thing work again. I assume the server's config and routing table are OK because it was working before (although quite some time ago). Would any of you experts be able to help? server.conf # Serveur TCP/666 mode server proto udp port 666 dev tun # Cles et certificats ca ca.crt cert server.crt key server.key dh dh1024.pem tls-auth ta.key 0 cipher AES-256-CBC # Reseau server 10.8.0.0 255.255.255.0 #push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 208.67.222.222" push "dhcp-option DNS 208.67.220.220" push "redirect-gateway def1" keepalive 10 120 # Securite user nobody group nogroup chroot /etc/openvpn/jail persist-key persist-tun comp-lzo # Log verb 3 mute 20 status openvpn-status.log log-append /var/log/openvpn.log client.conf # Client client dev tun proto udp remote *my server's ip address*:666 cipher AES-256-CBC # Cles ca ca.crt cert client1.crt key client1.key tls-auth ta.key 1 # Securite nobind persist-key persist-tun comp-lzo verb 3 Routing table on debian server when OpenVPN server is running: Destination Gateway Genmask Indic Metric Ref Use Iface 10.8.0.2 * 255.255.255.255 UH 0 0 0 tun0 10.8.0.0 10.8.0.2 255.255.255.0 UG 0 0 0 tun0 my server's ip * 255.255.255.0 U 0 0 0 eth0 default 72815.trg.dedic 0.0.0.0 UG 0 0 0 eth0 Routing table on Windows 7 client (OpenVPN not working) =========================================================================== Interface List 19...00 f0 8a 1b 6e 5c ......TAP-Win32 Adapter V9 12...90 2e 34 33 84 7b ......Atheros AR8151 PCI-E Gigabit Ethernet Controller ( NDIS 6.20) 1...........................Software Loopback Interface 1 12...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter 13...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface 16...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #2 =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 192.168.1.1 192.168.1.11 20 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 192.168.1.0 255.255.255.0 On-link 192.168.1.11 276 192.168.1.11 255.255.255.255 On-link 192.168.1.11 276 192.168.1.255 255.255.255.255 On-link 192.168.1.11 276 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 192.168.1.11 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 192.168.1.11 276 =========================================================================== Persistent Routes: None IPv6 Route Table =========================================================================== Active Routes: [...] =========================================================================== Persistent Routes: None And when the link is established between my client and the server: The server's routing table stays the same.

'Gateway' value is empty on client's side (in the adapter's "status" window). Client has got no internet access when the link is up. Ideal configuration: I only want the client to be able to use the server's Internet access and access its resources (MySQL server in particular). I do not need or want the server to access the client's local network. The client needs to be able to access it's local network, although all Internet traffic should be redirected to the VPN link. I spent a considerable amount of time on this but it's still not working, any help would be much appreciated. Thanks :)

• Connecting via ShrewSoft VPN client means no LAN internet access (Windows 7 64 bit) - any advice please?

  - by iwishiknewmoreaboutnetworking

  I have a Windows 7 64 bit desktop machine which is connected to a LAN. I recently installed ShrewSoft VPN client v 2.1.7 on my machine so that I can connect to a license server hosted by my customer. They are running a Cisco VPN server and I originally tried (unsuccessfully!) to use the Cisco VPN client for Windows 64 bit but the default gateway wasn't being configured correctly after loading in my pcf file. Using ShrewSoft I am able to import the same pcf file, and successfully connect to the machine I need to using the VPN client software. The client machine I need to connect to has IP address 1.52.90.33. The problem is that when I am connected to the customer network using the VPN client application (and after a few minutes) I lose my LAN internet connection. I can only presume that this is because, by default the ShrewSoft VPN client application automatically tunnels all traffic through the VPN connection. I know there is an option to switch off the "Tunnel All" option on the Policy tab of the application and enter a Remote Network Resource (to "Include" or "Exclude") as "Address" and "Netmask" IP addresses however I am not sure what I need to enter here. Here is my ipconfig output before connecting to the VPN (with suffixes blanked out): Windows IP Configuration Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : ***.*** Link-local IPv6 Address . . . . . : fe80::8de3:9dbe:393a:33ba%11 IPv4 Address. . . . . . . . . . . : 150.237.13.17 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 150.237.13.1 Tunnel adapter 6TO4 Adapter: Connection-specific DNS Suffix . : ***.*** IPv6 Address. . . . . . . . . . . : 2002:96ed:d11::96ed:d11 Default Gateway . . . . . . . . . : 2002:c058:6301::c058:6301 Tunnel adapter Local Area Connection* 9: Connection-specific DNS Suffix . : IPv6 Address. . . . . . . . . . . : 2001:0:4137:9e76:2cf9:38c4:6912:f2ee Link-local IPv6 Address . . . . . : fe80::2cf9:38c4:6912:f2ee%12 Default Gateway . . . . . . . . . : Tunnel adapter isatap.***.***: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : ***.*** Here is my route print output before connecting to the VPN: =========================================================================== Interface List 11...20 cf 30 9d ec 2a ......Realtek RTL8168D/8111D Family PCI-E Gigabit Ethern et NIC (NDIS 6.20) 1...........................Software Loopback Interface 1 14...00 00 00 00 00 00 00 e0 Microsoft 6to4 Adapter 12...00 00 00 00 00 00 00 e0 Teredo Tunneling Pseudo-Interface 13...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #2 =========================================================================== IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 150.237.13.1 150.237.13.17 2 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 150.237.13.0 255.255.255.0 On-link 150.237.13.17 257 150.237.13.17 255.255.255.255 On-link 150.237.13.17 257 150.237.13.255 255.255.255.255 On-link 150.237.13.17 257 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 150.237.13.17 257 255.255.255.255 255.255.255.255 On-link 12

• having 2 ip's on a debian 7 box

  - by David

  I just installed Debian Wheezy on my homeserver. I want to assign 2 ip's to it on the same network interface, 1 static ip (eth0) and 1 dynamic ip (eth0:1). I know it doesn't make much sense but I need it to test something. I edited my /etc/network/interfaces to be like this: auto lo eth0 eth0:1 iface lo inet loopback iface eth0 inet static address 192.168.178.240 network 192.168.178.0 netmask 255.255.255.0 broadcast 192.168.178.255 gateway 192.168.178.1 iface eth0:1 inet dhcp when I bring up eth0:1 (ifup eth0:1) I get the following error (eth0 works fine) Bind socket to interface: No such device Failed to bring up eth0:1. is it even possible to have a dynamic and static ip on the same network adapter?

• Remove a known network from Windows 8

  - by Edward Brey

  When Windows 8 detects a network based on the assigned IP address, netmask, default gateway, etc., it remembers the network along with the setting you give it as a public or private network. If you change the configuration of a network (e.g. reconfigure your router), Windows may determine you are on a new network and assign it a name of Network 2 or YourAPN 2. This less-than-friendly name shows up in many places in the Windows 8 UI, but unlike the good old days of Windows 7, there doesn't appear to be any UI to merge or delete these networks. What's the best way to merge or delete networks you don't want?

• ubuntu server in a vm, can't connect to internet

  - by jessh

  I'm attemtping to host my own development web server in a virtual box guest, Ubuntu Server. I would like this virtual machine to be accessible from not only my home network, but outside the LAN as well. As such, I've set up a static IP (so I can later forward ports to this static IP.) My virtual box settings have this vm only using one adapter -- in bridged mode. Here's what my /etc/network/interfaces looks like: iface eth0 inet static address 10.0.1.203 /*this is outside the DHCP range*/ netmask 255.255.255.0 gateway 10.0.1.1 network 10.0.1.0 broadcast 10.0.1.255 dns-nameservers: 8.8.8.8 8.8.8.4 Here's what the output of ifconfig looks like: https://dl.dropbox.com/u/2241201/locker/ubuntu.png My Host is a mac mini, running OS X 10.7.

• What is the network address (x.x.x.0) used for?

  - by Shtééf

  It appears to be common practice to not use the first address in a subnet, that is the IP 192.168.0.0/24, or a more exotic example would be 172.20.20.64/29. The ipcalc tool I frequently use follows the same practice: $ ipcalc -n -b 172.20.20.64/29 Address: 172.20.20.64 Netmask: 255.255.255.248 = 29 Wildcard: 0.0.0.7 => Network: 172.20.20.64/29 HostMin: 172.20.20.65 HostMax: 172.20.20.70 Broadcast: 172.20.20.71 Hosts/Net: 6 Class B, Private Internet But why is that HostMin is not simply 64 in this case? The 64 address is a valid address, right? And whatever the answer, does the same apply to IPv6? Perhaps slightly related: it also appears possible to use a TCP port 0 and an UDP port 0. Are these valid or used anywhere?

• Bringing the xenbr0 interface up on XEN under Ubuntu 8.04

  - by iyl

  I installed XEN on Ubuntu 8.04 using this tutorial: http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories but after I reboot with the XEN kernel, I don't have xenbr0 device. I see that network-bridge script runs and it creates peth0 device, but not xenbr0. I have a very basic IP setup, with a single static IP defined in /etc/network/interfaces. The only unusual thing is that my hosting (1&1) gave me a netmask 255.255.255.255, so I had to add the default gateway with this script: /sbin/route add -host 10.255.255.1 dev eth0 /sbin/route add default gw 10.255.255.1 Everything else is plain vanilla Ubuntu 8.04.

• How to make all of my IPs works in HyperVM XEN?

  - by user758667

  I've installed HyperVM on CentOS 5.8 final to make XEN VPS. I have 5 IPs, and added them to an IPPool. They are from *.123 to *.126. But when I add Virtual machines, just the first one (which indicate to *.123 ip) works well. I mean I can ssh to it by "works well" and when I want ssh to the other ones ( *.124 *.125 ...) it says : ssh: connect to host *.124 port 22: Connection timed out after a while. I alos set gateway and netmask as it shows in my server IPAdresses for device eth0 (it doesn't make any difference if I set these or not, I get same error). What should I do now? Thanks.

• Ubuntu 11.04 Static IP doesn't take

  - by mrduclaw

  I'm trying to set a static IP address in Ubuntu 11.04. I did a server install. I edited my /etc/network/interfaces file to include: auto eth0 iface eth0 inet static address 10.0.0.100 netmask 255.255.255.0 gateway 10.0.0.1 When I do a /etc/init.d/networking restart this appears to take. After awhile though, that 10.0.0.100 will turn into something dished out by the DHCP server. My problem appears to be similar to this: Ubuntu intrepid - static IP networking keeps restarting with DHCP But I don't have Gnome installed. Is there anything else that's running in the background that could be doing this? And if so, how do I disable it?

• ssh can't connect after server ip changed

  - by Kery

  I have a server with ubuntu installed. After I change the network configuration and restart server, ssh client can't connect server any more. But in the server I can use ssh client to connect itself and the netstat command shows that sshd is listening port 22. And in my computer (win7) ping command is OK to server's new IP. The configuration in /etc/network/interfaces is: auto eth0 iface eth0 inet static address 10.80.x.x netmask 255.255.255.0 gateway 10.80.x.1 I'm very confused about this. Hope somebody can give me some idea. Thank you in advance!!!

• Cisco WLAN Controller not pushing out DHCP addresses, what else could it be?

  - by Name

  On our Cisco WLAN Controller web interfaces, in Controller Interfaces, I have made a new interface with these settings: VLAN Identifier 202 IP Address 172.16.202.1 Netmask 255.255.255.0 Gateway 172.16.202.254 Primary DHCP Server 172.16.100.3 Secondary DHCP Server 172.16.100.2 Port: LAG I've also made a new WLAN and assigned it to the above interface. I have saved changes. But our wireless devices, although they seem to authenticate with the WLAN fine, they always get stuck on "obtaining DHCP address", so it seems the WLAN Controller isn't pushing out DHCP addresses to our devices. We do have a DHCP scope for the above in Windows Server 2008 R2 and everything there seems fine. If I connect a device with a static address (e.g. 172.16.202.10), it will connect. Stuck on what to do :(

• Windows XP doesn't like small subnets?

  - by erniedwork

  This totally sounds like a bug to me, because my subnet mask and IP address should be valid by all accounts. My ISP has assigned me a fixed IP address of 65.110.7.20, with a subnet mask of 255.255.255.252. Which sounds about right, because we're trying to set up a router with a /31 network - just 4 ip addresses. But when I try to set this IP and netmask up in Windows XP, I get the following error: "The combination of IP address and subnet mask are invalid. All of the bits in the host address portion of the IP address are set to 0." But they're not all set to 0. That would be a subnet mask of 255.255.255.255. Even then, that too is a valid subnet mask, consisting of a network of 1 IP address. Is there a way around this? A registry hack maybe?

• Setting primary IP for VPS (out of 2 available)

  - by Flyer

  I've got a little problem. My VPS (Debian box) has 1 primary IP address, but now my hosting provider decided to assign me another one due to problems with first one. Let's say new IP is 91.222.152.20 and old one 91.221.190.170. How should I make 91.222.152.20 primary one, so that everything works on this address instead of 91.221.190.170 (like ftp, mysql etc) I tried editing /etc/newtwork/interfaces setting iface eth1 inet static address 91.222.152.20 netmask 255.255.252.0 network 91.222.152.0 broadcast 91.222.155.255 gateway 91.222.152.1 I know that network is 91.222.152.0/22 so I assume that above configuration should be right. Saved, rebooted and that ended pretty bad. Couldn't even ping box on old or new IP. Had to revert to working one. So question is. What am I doing wrong and how to do it right?

• Two IP ranges on eth1 configuration for centos 6.2

  - by Trickzzz

  i have a dedicated server, with "Virtuozzo" on it running VPS's. I have: eth0 - which is configured to the internal network, that one is fine. Now I have: eth1 - which has two ranges routed through this device. x.x.134.x (which has 12 IP's sequentially) x.x.132.x (which has 5) eth1: DEVICE="eth1" HWADDR="00:25:90:37:65:67" NM_CONTROLLED="yes" ONBOOT="yes" IPADDR="x.x.134.x" NETMASK="255.255.255.240" GATEWAY="x.x.134.x" I tried using this with another file as well named "ifcfg-eth1:1" in /etc/sysconfig/network-scripts/ any ideas why the containers on eth1:1 would not link up to the network? Virtuozzo also thinks that eth1:1 is the primary network now, which isn't right?

• VLAN Configuration Conflict, Who Wins?

  - by Kevin

  I'm new to VLANs, so take that into consideration... Lets say that I had a server set up to create a virtual interface that is set to be tagged as VLAN 3. For example, the following Debian config: iface eth0.1 inet static address 192.168.1.1 netmask 255.255.255.0 Now on my switch, lets say that I have the port that the aforementioned server connects to, set to VLAN 4... Who wins? What are the packets tagged as, as viewed by the rest of the network?

• Ubuntu 9.10 and Squid 2.7 Transparent Proxy TCP_DENIED

  - by user298814

  Hi, We've spent the last two days trying to get squid 2.7 to work with ubuntu 9.10. The computer running ubuntu has two network interfaces: eth0 and eth1 with dhcp running on eth1. Both interfaces have static ip's, eth0 is connected to the Internet and eth1 is connected to our LAN. We have followed literally dozens of different tutorials with no success. The tutorial here was the last one we did that actually got us some sort of results: http://www.basicconfig.com/linuxnetwork/setup_ubuntu_squid_proxy_server_beginner_guide. When we try to access a site like seriouswheels.com from the LAN we get the following message on the client machine: ERROR The requested URL could not be retrieved Invalid Request error was encountered while trying to process the request: GET / HTTP/1.1 Host: www.seriouswheels.com Connection: keep-alive User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.9 (KHTML, like Gecko) Chrome/5.0.307.11 Safari/532.9 Cache-Control: max-age=0 Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,/;q=0.5 Accept-Encoding: gzip,deflate,sdch Cookie: __utmz=88947353.1269218405.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none); __qca=P0-1052556952-1269218405250; __utma=88947353.1027590811.1269218405.1269218405.1269218405.1; __qseg=Q_D Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Some possible problems are: Missing or unknown request method.

Your cache administrator is webmaster. Below are all the configuration files: /etc/squid/squid.conf, /etc/network/if-up.d/00-firewall, /etc/network/interfaces, /var/log/squid/access.log. Something somewhere is wrong but we cannot figure out where. Our end goal for all of this is the superimpose content onto every page that a client requests on the LAN. We've been told that squid is the way to do this but at this point in the game we are just trying to get squid setup correctly as our proxy.
