  • How to setup GoDaddy dns forwarding

    - by skerit
    I have a VPS in England and a hosting account with hostgator. I use GoDaddy to manage my domain name settings. My VPS is mainly used for mail and certain other services. The actual site is hosted at hostgator I had a cname called "www" which would point to mydomain.com, at hostgator All the rest would point to my vps. (The "A" host, @) Now Hostgator lost my original domain name, so pointing to that leads to a fake website. But you can't just make www point to an ip adres. No. I tried adding an "A" host which would point to the hostgator ip-adres and then I would point the "www" cname to that "A" host. But that does not work. Can anyone shed some light on this?

  • How to use X11 forwarding with putty

    - by Neuquino
    I have a VM with RHEL 5 without an X server. My host has Windows 7. I need to connect to the VM and redirect the X11 output of the commands to my host. I know that if my host were a GNU/Linux machine it would be as easy as ssh -X . I'm ussing PuTTy to connect by SSH to the VM, I tried enabling X11 forward option in PuTTy config, but nothing happened. Have you ever done this? I'm quite advanced with GNU/Linux, but a newbie with this toy of Winbug$ 7.

  • Internet Forwarding With Qemu?

    - by ConfusedGuy
    I'm using kvm and qemu to run a windows virtual machine, but I'm trying to get internet on that machine. I've been reading about all this bridging and stuff that is done to do that, but I was wondering if there was a simpler way, to just forward my internet connection (since I'm connected on the host machine) through qemu to the guest operating system. Is this possible? Thanks

  • ssh X11 forwarding issue

    - by bbuser
    I have put ForwardX11 in my ~/.ssh/config and then I start a X11 application like this: ssh -f user@host 'someapp; sleep 1' This works fine. The application someapp has a button which opens a viewer application via a shell script viewer.sh. When I press the button the viewer comes up. This is all good and as expected, but if I do ssh -2 -f user@host 'someapp; sleep 1' there's trouble. someapp starts very well, but if I click the button the viewer doesn't show up. As the viewer is called via a shell script, I replaced the call with xclock and the situation was exactly the same - I think the viewer is not to blame. The situation is the same on Linux and AIX. The reason I need -2 is that I finally want to use connection multiplexing and this does only work with version 2. The reason for the sleep 1 is that it didn't work otherwise;-) To add more confusion, with ssh -2 -f user@host 'xterm &; app; sleep 1' the viewer works as long as the xterm is open. When I close xterm ssh -v outputs the following debug1: channel 1: FORCE input drain debug1: channel 0: free: client-session, nchannels 3 debug1: channel 1: free: x11, nchannels 2 and from that moment the viewer doesn't show when I press the button. I also replaced the viewer application with a script that writes the $DISPLAY variable to a file. The variable is always set correctly.

  • port forwarding on windows server 2008 to Hyper-v machines

    - by This is it
    I have a host machine (win server 2008 R2) with several Hyper-V virtual machines. I want to be able to redirect certain ports of host to virtual machines. There is virtual network connection between host and virtual machines (192.168.10.xxx). Host is also attached to external network (10.10.10.123). Virtual machines have several other networks between them. E.g., I want to be able to redirect traffic from 10.10.10.123 12345 to 192.168.10.321 54321 I tried RRAS in windows server but for it to work Default gateway to 10.10.10.123 has to be set in virtual machines. Virtual machines can not be on external network.

  • AWS forwarding email to a gmail account

    - by user2433617
    So I registered a domain name. I then set up a static webpage using aws (S3 and Rout53). Now what I want to do is forward any email I get from that custom domain name to a personal email address I have set up. I can't seem to figure out how to do this. I have these record sets already: A NS SOA CNAME I believe I have to set up an MX record but not sure how. say I have the custom domain [email protected] and I want to redirect all email to [email protected]. The personal email account is a gmail (google accounts) email address. Thanks.

  • ssh port forwarding / security risk

    - by jcooper
    Hi there, I want to access a web application running on a web server behind my office firewall from an external machine. We have a bastion host running sshd that is accessible from the Internet. I want to know if this solution is a bad idea: Create an account on the bastion host with shell=/bin/false and no password ('testuser') Create a ssh RSA key on the external machine Add the public RSA key to the testuser's authorized_keys file ssh to the bastion host from the external host using: ssh -N 8888:targethost:80 run my tests from the external host shut down the ssh tunnel I understand that if my RSA private key were compromised then someone could ssh to the bastion host. But are there other reasons this solution is a bad idea? thank you!

  • Question about Domain Forwarding [beginner]

    - by Jack W-H
    Hello folks Just a quick beginner's question here. I have a webapp located at domainxyz.com, and it generates short URLs for long posts automatically - so rather than visit domainxyz.com/reallylongpostnamehere I can just type domainxyz.com/a5c and be taken there automatically. However, I've bought a shorter domain name - short.com - and I want to be able to visit short.com/a5c and be redirected (or forwarded) to domainxyz.com/a5c. Or short.com/7f0 -- domainxyz.com/7f0. This way, although it seems a tad illogical it saves me setting up another hosting account on short.com to deal with the URL shortening. Is this possible? I realise you can forward domains, but, can you forward domains AND forward the URL segments? Thanks! Jack

    - by Danialzo
    I have Hyper-V running on a windows 2008. I got a new ip stack from the data center to be set on my virtual machines. But I have difficulties to set these IPs on my VMs because they are on different network. my current server ip is xxx.xxx.18.6 with MASK : 255.255.255.224 and the GW is xxx.xxx.18.1 my new ip stack is xxx.xxx.168.176/29 I can use RRAS to achieve this. Do I need to create another NIC? How do I make these VMs reachable from outside?

  • centos 6.3 kvm external ip forwarding to guests

    - by user1111702
    I have a centos 6.3 server with kvm installed. The server has 4 external ips and one NIC. 176.9.xxx.xx1 176.9.xxx.xx2 176.9.xxx.xx3 176.9.xxx.xx4 I use the following configuration ifcfg-eth0 as slave to ifcfg-br0 the configuration in ifcfg-eth0 is DEVICE=eth0 ONBOOT=yes BRIDGE=br0 HWADDR=14:da:e9:b3:8b:99 and in the ifcfg-br0 DEVICE=br0 TYPE=Bridge BOOTPROTO=static BROADCAST=176.9.xxx.xxx IPADDR=176.9.xxx.xx1 NETMASK=255.255.255.0 SCOPE="peer 176.9.xxx.xxx" and I have 3 more aliases for br0 , br0:1 to get the trafic from the second external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx2 NETMASK=255.255.255.248 ONBOOT=yes br0:2 to get the trafic from the third external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx3 NETMASK=255.255.255.248 ONBOOT=yes br0:3 to get the trafic from the second external ip DEVICE=br0:1 IPADDR=176.9.xxx.xx4 NETMASK=255.255.255.248 ONBOOT=yes The above settings work fine and I recieve the trafic from all the external ips. My problem is that I want to pass the trafic from external ip to specific virtual guest on my server. ie trafic that comes from 176.9.xxx.xxx2 must pass to virtual machine 1 176.9.xxx.xxx3 must pass to virtual machine 2 176.9.xxx.xxx4 must pass to virtual machine 3 Can you please help me how to achieve this ? What are the settings on the host and what should I do to the guests. Thank you in advance

  • IP Masquerade and forwarding

    - by poelinca
    Hi all , i got a dedicated server running ubuntu server 10.10 with 3 ip adresses on the same eth card ( example: eth0 192.168.0.1 , eth0:0 188.78.45.0 , eth0:1 ... ) with a 3 virtual machines running ( virtualization technologi used is lxc but i don't think this matters too much ) . Now i need to redirect all ports opened ( using ufw to close/open ports ) from the ip 188.78.54.0 ( eth0:0 ) to a virtual machine ip ( let's say for example 192.168.2.3 ) , all requests made by a virtual machine should be redirected back to the virtual machine that made the request ( in this example 192.168.2.3 ) . Lets say the second vm has the ip 192.168.2.4 now i need to redirect all opened ports to from eth0:1 to this ip and viceversa . And so on and so on , what are the iptables/ufw rules to get this done ? and where to save them ( witch config file ) so they stay the same after reboot . In a few words redirect all requests comming from/to eth0:0 to a certan ip , all requests comming from/to eth0:1 to another ip ... Remember i'm saying all ports opened becouse they might be dynamicly changed . p.s. please excuse my bad english

  • Samba port forwarding?

    - by Robert
    Here's my situation: On my network, most of the clients are on an outside router. Router 1 192.168.1.1 | | - Client | Router 2 192.168.1.2 to router 1, | 192.168.2.1 to clients within | Samba server - 192.168.2.25 I cannot figure out how to get clients under router 1 to access the Samba shares in router 2. I have forwarded ports 139 and 445 to the appropriate machine in router 2 but machines in router 1 still cannot access the server. How would I set this up?

  • Forwarding sent mail through postfix

    - by D_f-r
    So I've successfully forwarded mail from my postfix server to remote Gmail accounts using /etc/aliases and newaliases. But now of course those Gmail accounts cannot send email originating from the original, aliased addresses without further configuration. I examined the Gmail configuration and found that it is indeed possible to forward sent emails via SMTP through the postfix server, but an account with a password is necessary. Even though those accounts are simply aliases, is it possible to give them passwords to facilitate replying to emails they forward? Or is an entirely different configuration set-up necessary?
