  • Setting up a static IP address (public) in Ubuntu

    - by ycseattle
    I have a business class internet connection and need to setup a static ip address for a machine. I did a search online and only find how to setup static local ip addresses (like 192.168..). I tried the same technique, and only setup the ip address and netmask, but after restart networking the computer could not connect to the outside world. This is what I did: 1) edit /etc/network/interfaces iface eth0 inet static address 173.10.xxx.xx netmask 255.255.255.252 2) edit /etc/resolv.conf search wp.comcast.net nameserver xx.xx.xx.xxx nameserver xx.xx.xx.xxx 3) restart network sudo /etc/init.d/networking restart Now the last step didn't report error, ifconfig shows the ip address was set, but this server cannot connect to outside world, ping google.com and reports "unknown host google.com". Any ideas?

  • cPanel default email address and BCC forward

    - by trante
    In my cPanel I redirect all unknown emails to my gmail address of [email protected]. I set it from default email address option of cPanel of example.com. I wrote a filter in gmail. When I receive email thait is sent to example.com I move it to folder X. But when I receive an email that is sent to example.com as BCC, I don't see my email address in headers, so filter doesn't work. Email comes to gmail inbox, which I don't like. So I need to forward BCC type emails to [email protected]. Or add my email address before forwarding to gmail.

  • Configure IIS to rewrite IP Address to Site Name

    - by Bath Man
    So i've started my first web site from home, and I'm trying to get it up and running and google crawlable and the like, but I can't seem to figure out how to have my site name returned in the address bar instead of my IP address. I've purchased a domain name for my site on Godaddy and then set it to redirect to my site. When you type in the domain name, you get redirected to http://0.0.0.0/default.aspx (not my real IP obviously), and that stays in the user's address bar. In order to fix that temporarily, I've set up masking on Go Daddy which keeps the URL in the address bar, but just shows my website in a frame. This is fine for users visiting the site, however any kind of automated robot such as GoogleBot cannot discover my content because of the frame. I've looked into ISAPI filters and server-site-rewriting, and the like... but I just can't quite figure out how to do what I need it to do. Any simple suggestions or links would be appreciated.

  • Httpd restart "Address already in use" error

    - by mtndesign
    I have an .rpm, which I created. In its %post part, I do some stuff, and in the end of this script, i call service httpd restart. It gives the following error: + service httpd restart Stopping httpd: [FAILED] Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:81 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:81 no listening sockets available, shutting down Unable to open logs [FAILED] I got this from the rpm verbose installing (-vv). So I know its about httpd restart itself, nothing else. The according to netstat only one process (httpd) is listening on port 81. $ sudo netstat -nlp | grep 81 tcp 0 0 :::81 :::* LISTEN 29670/httpd I don't understand, why running http FAILS at stop, and FAILS again in start. Any ideas how to solve this?

  • Force an LXC container to use its own IP address

    - by emma sculateur
    Sorry if this question has already been asked. I could not find it, I have this setup : +---------------------------------------------------------------------------------------------+ |HOST | | | | +-------------------------------------------------+ | | | UBUNTU-VM | | | | | | | | +-------------------+ | | | | |UBUNTU-LXC | | +------------------+ | | | | 10.0.0.3/24 | 10.0.0.1/24 | |OTHER VM | | | | | eth0-----lxcbr0----------eth0-----------br0----------eth0 | | | | | | 192.168.100.2/24| 192.168.100.1/24 |192.168.100.3/24 | | | | +-------------------+ | +------------------+ | | +-------------------------------------------------+ | +---------------------------------------------------------------------------------------------+ When I ping 192.168.100.3 from my UBUNTU-LXC, the source IP address is automatically changed to 192.168.100.2 by UBUNTU-VM. It's like having a NAT, whereas I really want my UBUNTU-LXC to talk with it own IP address. Is there any way to do this ? Edit : these info may be relevant : I am using KVM +libvirt to set up my VMs Here is how I create my interface in UBUNTU-VM : <interface type='bridge'> <mac address='52:54:00:cb:aa:74'/> <source bridge='br0'/> <model type='e1000'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x09' function='0x0'/> </interface>

  • Transferring domains when registered owner's email address is incorrect

    - by www.jacob-
    Years ago I registered some domains using a now expired university email address. The other contact details for the registered owner (postal address and phone number) are still correct. In order to change/update the email address, the registrar wants to charge £20 a domain. I would like to transfer the domains away from the current registrar. I can unlock the domains and generate an auth code. However, I cannot authorise the transfer by email as any emails sent to the registered owner's address will bounce. This seems to rule out most registrars I have tried. Are there any ways to transfer these domains without paying the £20 fee to update the registered owner's details?

  • Rewriting to address on postfix local aliases

    - by Wade Williams
    I was running into the common problem that mail for "root" on my system was having $mydomain appended, and because $mydomain is not in $mydestination, the mail was being sent to our central mail server as "root@domain." I cannot add $mydomain to $mydestination, because if I understand it correctly, that would mean all mail addressed to $mydomain would be looked up locally, and if an alias does not exist, delivery would fail. So, I followed these instructions: Delivering some, but not all accounts locally which seems to have resolved the problem. Mail for "root" is now expanded according to /etc/aliases and delivered to the non-local address I desire. The one oddity however is that the "To:" address still reads "root@domain." Is there any way I can get the "To" address to be the one that the alias directed its delivery? So for example, if my alias says that mail for "root" should go to "hostname-admin@domain" is there any way the "To" address can be rewritten as "hostname-admin@domain?" Currently it still shows as "root@domain."

  • Access Google Apps Global Address List from Thunderbird

    - by Roy
    We're considering using Google Apps as groupware, with our Mac and Linux users (and likely a few of the Windows users as well) accessing mail and calendar using Thunderbird with Lightning. We seem to have worked out most features, but have not found a way to access Global Address List. Is there a way to sync the Global Address List to Thunderbird? Update: The Zindus addon as suggested by @superuser, does not have support for Global Address List from Google Apps (it does however support GAL from a Zimbra server)

  • Assign fixed IP address via DHCP by DNS lookup

    - by Janoszen
    Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

  • Need to set mailx variable to specify the From address

    - by user256817
    Running Oracle Linux 5.8 (which is just re-branded RedHat EL 5.8) I must change the From address. But we have scripts that use mailx which cannot be re-written to use any extra flags, so I'd like to use internal variables instead, which I see on the linux.die.net manpage on mailx is an alternative to the -r flag: -r address Sets the From address. Overrides any from variable specified in environment or startup files. Tilde escapes are disabled. The -r address options are passed to the mail transfer agent unless SMTP is used. This option exists for compatibility only; it is recommended to set the from variable directly instead. (Source: http://linux.die.net/man/1/mailx) How can we use these mailx variables? I tried adding this to /root/.mailrc, no go: set [email protected] I also added that to /etc/mail.rc with no gold. So I am turning to you, SuperUsers...

  • Address already in use - Amazon AWS

    - by Peter
    I've run into a really weird issue. I was debugging a server 500 error script on our EC2 instance and found that we didn't have ioncube loaders installed. So I went to go install them and I created a new file at /etc/php.d/zend.ini and initially I inserted the value of extension=/usr/local/ioncube/ioncube_loader_lin_5.3.so and restarted httpd at which point it told me: The ionCube Loader is a Zend-Engine extension and not a module Please specify the Loader using 'zend_extension' in php.ini PHP Fatal error: Unable to start ionCube Loader module in Unknown on line 0 So I changed the contents of zend.ini to zend_extension=/usr/...etc. Now when I attempt to restart httpd I get this error: Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80 (98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down Unable to open logs I can't even run /etc/init.d/httpd stop without it erroring. I've since removed zend.ini to see if that's what caused it and it doesn't seem to be. Any ideas?

  • How to have 2 windows machines on the same network with the same IP address

    - by Stu
    I have a custom made ADC device that is spitting out data by addressed UDP packets. I have that device plugged into a 4 port switch. I have one windows embedded standard 7 machine which is the normal recipient of that data. To be able to receive the data (Using LabVIEW) the windows network adapter IPv4 settings must have a static IP address that corresponds to the UDP packet destination. I would like to add a second windows machine (This one is just regular Win 7 Pro) to simultaneously catch the data, however with all devices connected to the switch, the Win 7 Pro machine recognizes an IP address conflict and will not take the setting for the required static IP address. (The network adaptor settings show that the correct value has been entered but ipconfig shows that it is not actually set.) Neither windows machine needs to transmit network data, they only need to be able to receive the UDP data from the ADC device. Is there any way to disable this IP address conflict detection 'feature' of windows networking?

  • OS X - forwarding external port to local loopback address

    - by Rory Fitzpatrick
    I have an HTTP service bound to port 8000 that I want to access from another computing on the network, but I can't seem to connect using the external IP address of the machine (e.g. 192.168.0.105). I've checked the OS X firewall isn't running, so I'm assuming the issue is the service is only bound to the IP address 127.0.0.1, and not the external IP address. What would be the easiest way to temporarily forward external connections on port 8000 to 127.0.0.1:8000?

  • question about IP address

    - by baddogai
    i know how IP basically works, and knows that an IP address composed of a network ID portion and a host ID portion, but when I type a IP address ,say "8.8.8.8" into the web browser, i DIDN'T supply any subnet mask information, so how does the browser know where the dividing line is between the network ID and host ID? since 8.8.8.8 may mean 8.8.8.8/8, 8.8.8.8/24 etc. In a nutshell, the IP address I supplied is ambiguous.

  • Routing based on source address in Windows Server 2008 R2

    - by rocku
    I'm implementing a direct routing load balanced solution using Windows Server 2008 R2 as back-end server. I've configured a loopback interface with the external IP address. This works, I am receiving packets with the external IP address and respond to them appropriately. However our infrastructure requires that traffic which is being load-balanced should go through a different gateway then any other traffic originating from the server, ie. updates etc. So basicly I need to route packets based on source address (external IP) to another gateway. The built-in Windows 'route' command allows routing based on destination address only. I've tried setting a default gateway on the loopback interface and mangled with weak/strong host send/receive parameters on the interfaces, however this didn't work. Is there any way around this, possibly using third party tools?

  • Setting up a fake email address to trap spammers

    - by Brent
    I have heard it suggested that we set up a special email address, with it's only purpose being to be harvested. Then blacklisting every sender that targets this address. I'm wondering: if anyone else has tried this how do you go about doing it (ie - put the address in a hidden field on your website - or better ways?) does it work? Is there anything to watch out for when trying this (ie. legitimate senders using harvested addresses?)

  • NETSH : Set default ip address for an interface with multiple Ips

    To test a load balancer I need to switch my ip address several time a day, and keep other ips routing trough other Wans.

  • Not having address/phone number in WHOIS database?

    - by HighCommander4
    When I sign up for an account with a domain name registrar like 10dollar.ca, it asks for my address and phone number. Will these show up when someone does a WHOIS lookup on my domain name? I noticed that when you do a WHOIS lookup on some websites (e.g. http://www.chrismanieri.ca), no address/phone number comes up. I want mine to be like that, too (don't want my address/phone number exposed to the public).

  • forward all ports via htaccess to new address

    - by user875933
    I have a chat server running on my local machine that listens to different ports. I want to use the sub-domain of one of my accounts to access it. I intend to manually change the redirect whenever my local machine gets a different ip address. So: chat.example.com:123 would redirect to dynamic.ip.address:123 I am trying to accomplish this with .htaccess and RewriteRule I have tried: RewriteEngine on RewriteRule ^(.*) http://dynamic.ip.address/ [L, R=302] but this doesn't work. When I try chat.example.com:123 nothing happens. When I input chat.example.com into the web browser, I get dynamic.ip.address Is .htaccess the right tool for this? I am using a simple web host that gives me ssh access, but not much more.

  • Exchange 2010 Prevent Authenticated Users From Sending Email From Any Address

    - by Chance
    I have recently been combating an SMTP AUTH attack in which one of my email accounts had been compromised and was being used to solicit spam. I have been able to identify the account and change the password however I would like to further restrict my exchange server. By default exchange 2010 allows for any authenticated user to specify any email address as the MAIL FROM address and it will accept it. Is there any way to restrict this so that only the authenticated account's email address will be able to be used as the MAIL FROM address? I have been looking through all ADPermissions for the SMTP connector however I can't find any documentation on how to accomplish this. Any suggestions would be greatly appreciated.
