  • Whitelist IP from google-authenticator in sshd pam

    - by spudwaffle
    My Ubuntu 12.04 server uses the google-authenticator pam module to provide two step authentication for ssh. I need to make it so that a certain IP does not need to type the verification code. The /etc/pam.d/sshd file is below: # PAM configuration for the Secure Shell service # Read environment variables from /etc/environment and # /etc/security/pam_env.conf. auth required pam_env.so # [1] # In Debian 4.0 (etch), locale-related environment variables were moved to # /etc/default/locale, so read that as well. auth required pam_env.so envfile=/etc/default/locale # Standard Un*x authentication. @include common-auth # Disallow non-root logins when /etc/nologin exists. account required pam_nologin.so # Uncomment and edit /etc/security/access.conf if you need to set complex # access limits that are hard to express in sshd_config. # account required pam_access.so # Standard Un*x authorization. @include common-account # Standard Un*x session setup and teardown. @include common-session # Print the message of the day upon successful login. session optional pam_motd.so # [1] # Print the status of the user's mailbox upon successful login. session optional pam_mail.so standard noenv # [1] # Set up user limits from /etc/security/limits.conf. session required pam_limits.so # Set up SELinux capabilities (need modified pam) # session required pam_selinux.so multiple # Standard Un*x password updating. @include common-password auth required pam_google_authenticator.so I've already tried adding a auth sufficient pam_exec.so /etc/pam.d/ip.sh line above the google-authenticator line, but I can't understand how to check an IP adress in the bash script.

  • Is this a solution for having multiple SSL certificates on the same IP

    - by Saif Bechan
    I am running CentOS running on a VPS. I read some guides on having multiple SSL certificates on the same system, but I can not get the basics to work. The guide I got that makes the most sense to me is the doing the following. In CentOS I can make virtual NIC's. So I made 2 virtual NIC's to start with. 192.168.10.1, 192.168.10.2. Now I work in ISP manager Pro, so this is listening on my primary ip 1.1.1.1 For each website I have them listening on 192.168.10.1:80, 192.168.10.1:443 In the hosts file I made the following 2 entries 192.168.10.1 1st.com 192.168.10.2 2nd.com Now the strange thing is that when I browser to 1st.com I do not get the website located at 192.168.10.1, I get the website located at my prim IP 1.1.1.1 Should I do something like forwarding or routing for this setup to work? And the basic question: Will this setup even work? Are the SSL certificates based on the IP adress, or are the based on the host name, 1st.com and 2nd.com.

  • IP routing Solaris 9 access the internet from local network

    - by help_me
    I am trying to configure the NICS on the Solaris Sparc server. My problem lies in getting out to the "Internet" from the local network.

  • Cisco 891w multiple VLAN configuration

    - by Jessica
    I'm having trouble getting my guest network up. I have VLAN 1 that contains all our network resources (servers, desktops, printers, etc). I have the wireless configured to use VLAN1 but authenticate with wpa2 enterprise. The guest network I just wanted to be open or configured with a simple WPA2 personal password on it's own VLAN2. I've looked at tons of documentation and it should be working but I can't even authenticate on the guest network! I've posted this on cisco's support forum a week ago but no one has really responded. I could really use some help. So if anyone could take a look at the configurations I posted and steer me in the right direction I would be extremely grateful.

  • How to Assign a Static IP Address in XP, Vista, or Windows 7

    - by Mysticgeek
    When organizing your home network it’s easier to assign each computer it’s own IP address than using DHCP. Here we will take a look at doing it in XP, Vista, and Windows 7. If you have a home network with several computes and devices, it’s a good idea to assign each of them a specific address. If you use DHCP (Dynamic Host Configuration Protocol), each computer will request and be assigned an address every time it’s booted up. When you have to do troubleshooting on your network, it’s annoying going to each machine to figure out what IP they have. Using Static IPs prevents address conflicts between devices and allows you to manage them more easily. Assigning IPs to Windows is essentially the same process, but getting to where you need to be varies between each version. Windows 7 To change the computer’s IP address in Windows 7, type network and sharing into the Search box in the Start Menu and select Network and Sharing Center when it comes up.   Then when the Network and Sharing Center opens, click on Change adapter settings. Right-click on your local adapter and select Properties. In the Local Area Connection Properties window highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button. Now select the radio button Use the following IP address and enter in the correct IP, Subnet mask, and Default gateway that corresponds with your network setup. Then enter your Preferred and Alternate DNS server addresses. Here we’re on a home network and using a simple Class C network configuration and Google DNS. Check Validate settings upon exit so Windows can find any problems with the addresses you entered. When you’re finished click OK. Now close out of the Local Area Connections Properties window. Windows 7 will run network diagnostics and verify the connection is good. Here we had no problems with it, but if you did, you could run the network troubleshooting wizard. Now you can open the command prompt and do an ipconfig  to see the network adapter settings have been successfully changed.   Windows Vista Changing your IP from DHCP to a Static address in Vista is similar to Windows 7, but getting to the correct location is a bit different. Open the Start Menu, right-click on Network, and select Properties. The Network and Sharing Center opens…click on Manage network connections. Right-click on the network adapter you want to assign an IP address and click Properties. Highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button. Now change the IP, Subnet mask, Default Gateway, and DNS Server Addresses. When you’re finished click OK. You’ll need to close out of Local Area Connection Properties for the settings to go into effect. Open the Command Prompt and do an ipconfig to verify the changes were successful.   Windows XP In this example we’re using XP SP3 Media Center Edition and changing the IP address of the Wireless adapter. To set a Static IP in XP right-click on My Network Places and select Properties. Right-click on the adapter you want to set the IP for and select Properties. Highlight Internet Protocol (TCP/IP) and click the Properties button. Now change the IP, Subnet mask, Default Gateway, and DNS Server Addresses. When you’re finished click OK. You will need to close out of the Network Connection Properties screen before the changes go into effect.   Again you can verify the settings by doing an ipconfig in the command prompt. In case you’re not sure how to do this, click on Start then Run.   In the Run box type in cmd and click OK. Then at the prompt type in ipconfig and hit Enter. This will show the IP address for the network adapter you changed.   If you have a small office or home network, assigning each computer a specific IP address makes it a lot easier to manage and troubleshoot network connection problems.

  • Impact of Changing IP Address of Outgoing IP Packets From My Network

    - by iamrohitbanga
    If I modify the source ip address of all outgoing ip packets from my network to an ip address belonging to someone else (while ensuring that the checksum is correct) then what will happen. Assume that I have a public IP address connected by a point-to-point link to an ISP. Will the ISP check that the IP address in my IP packets is correct or will it just forward the packets. I believe that ISP should just forward the packets. what mechanisms are present in the Internet that prevent this from happening?

  • Local IP address same as Google's external

    - by GRIGORE-TURBODISEL
    I'm exampling Google's IPs, but you get the idea. What happens if somebody configures a router's LAN address pool to range from 62.231.75.2 to 62.231.75.255, then his computer's IP address to 62.231.75.232 and someone else on the network tries to access Google? Or better off, is there any case in which someone in that network can, by merely attempting to access Google, accidentally bump into another computer on the network?

I know the first address could be in numbers but i've yet to find out how i could really find in some kind of order for that amount of addresses E.G: What technique could i use to make sure i'll actually be able to use all of the addresses

  • Chrome Equivalent of %s address bar trick in Firefox

    - by notbrain
    I was curious if there was an equivalent technique in Chrome to do address bar param string replacement like you can do in Firefox. If you create a bookmark and put a %s in the bookmark URL/address part, and set a keyword for the bookmark, you can do things like URL: http://php.net/%s Keyword: php Type in browser: php fopen End up at: http://php.net/fopen Is this making its way into Chrome or is there a way to do it?

  • Ubuntu Server static IP

    - by FoxyShadoww
    I am trying to give my server a static ip address. This seems to work without any problems, but I can't seem to get an internet connection after this process. I've also changed my dns server to 8.8.8.8 (google dns right?). OS: Ubuntu Server 12.04 x86 Environment: Virtualbox File: /etc/network/interfaces: auto eth0 iface eth0 inet static address 192.168.2.10 netmask 255.255.255.0 network 192.168.2.0 broadcast 192.168.2.255 gateway 192.168.2.1

  • NLB NIC w/ Static IP permanently "Acquiring Network Address" after adding more IP's to the cluster

    - by I.T. Support
    We have a 2 node NLB cluster. I recently added more IP's to the cluster range, after which point, the NLB NIC's on both of my nodes ended up in a permanent "acquiring network address" state. The cluster appears to be functioning despite this hang in acquiring an address. We've also rebooted the machines, and these NIC's remain in this state "acquiring network address" even after reboot, which I find troubling. Questions: Does anyone know where I can find documentation on how NLB binds to a NIC? (are there dll's involved, drivers, etc.) Does anyone know of any programs that have known incompatability issues with NLB? We have an application server installed on these NLB nodes (AOL Server) that interacts with the NIC's as well, and I suspect that it might be causing this issue. Before I go directly to Microsoft, I want to gather as much information as possible about the issue. Any help / guidance would be much appreciated...

  • If an visitors IP address contains "google" or a similar keyword, does this mean they were a crawler?

    - by Roscoe
    Hi, I have a huge list of IP addresses recorded from various visitors to a website. A huge amount of the visitors, in some months over 70%, came from IP addresses that contained keywords such as google, yahoo, bot, crawler, etc. Does this mean that those users were infact search engine crawlers? If so, why are their so many crawlers in my visitor records in comparison to genuine human visitors? (and if not what's the explanation?) Thanks in advance.

  • Routing static IP traffic on a Comcast Business Class IP Gateway (SMCD3G-CCR)

    - by Jakobud
    We are in the process of replacing our firewall, which is currently the only thing connected to our Comcast Business Class modem. Comcast gives us 5 static IP addresses. Currently, all traffic to all 5 static IPs goes directly to the existing firewall. Eventually, obviously all traffic will goto the new firewall, once the old firewall is removed from the network. But in the meantime, as we will have two firewalls plugged into the same Comcast modem, I need to route certain traffic to the new firewall instead of the old one. The firewall switchover is going to be slow and gradual as I am testing it, so I can't simply unplug the existing firewall and plug in the new one. So my question is, how do I tell the modem to route all traffic that goes to a specific IP to goto the new firewall instead of the old one? I've logged into the web interface for the modem, but the available options aren't very clear. There is a 1-to-1 NAT option (which I can't seem to get the interface for it to work properly) but I also see a "Static Routing" section. I always understood Static Routing to refer to routing data within the LAN though, so I'm not sure if that's what I'm looking for or not. Keep in mind, I'm not looking to do simple port forwarding. I'm wanting 100% of traffic to certain public static IPs to go to the specified connected firewall (I'll deal with service policies there). The modem is an SMC SMCD3G-CCR and is labeled as a Comcast Business Class Business IP Gateway. Any help or direction would be greatly appreciated.

  • Secondary IP (eth0:0) acts like main server IP

    - by George Tasioulis
    I have a CentOS server, configured with 4 consecutive IPs: eth0 5.x.x.251 eth0:0 5.x.x.252 eth0:1 5.x.x.253 eth0:2 5.x.x.254 The problem is that all traffic goes out to the internet with eth0:0 (5.x.x.252) as the source IP, instead of eth0. # curl ifconfig.me 5.x.x.252 How can I fix this, so that all traffic goes out via eth0, ie my main IP? PS: My server is VPS running on a Xen dom0, the latter being configured in routed mode networking. Thanks in advance!
