How would you assign a server a public static IP ?
Ok.. I guess to better ask my question... how to assign server public static IP centos? Like for example I am in the router itself.. where would I go to point ip 44.33.33.21. to ?> 192.168.1.4
What would be the most common in the routers?
I am running a modem in bridge mode to my server
I edit file /etc/sysconfig/network-scripts/ifcfg-eth0 code...
I do service network restart and get nothing ? No connection... Are there other files I need to edit?
i am trying to assign a Static IP address and for the life of my i cannot get it to work Can someone explain to me the easiest way to do it and if i restart the server it won't get lost either.
View 1 Replies View Relatedwe are running dedicated server with CentOS. We installed VMware in order to run a win2003 server. the problem is we need to access that server from outside (public).
1. the centos server has 2 NIC cards: eth0, eth1, eth2 with 2 public ips.
2. when vmware was installed we bind it to eth1.
3. we tried assigning eth1's public IP to the vmware machine and its not able to access anything outside.
4. tried to use NAT, bridged and host-only and no luck.
I want to assign a static ip address, my network/interfaces files shows
Code:
auto lo
iface lo inet loopback
am I correct to add
Code:
iface eth0 inet static
address 10.42.43.10
netmask 255.255.252.0
gateway 10.42.43.1
or is there more I need?
I have installed a ssh server on a computer (Ubuntu 10.04). This computer will be reboot many times, so the IP address is going to change. As a result, I couldn't connect with an other computer on this server via ssh. That's why I search a solution: either I assign a static IP on my server computer or I heard that I could use a dns name. I don't know if the latter solution is good so I hope to have some precisions. Also, I tried to have a static IP by editing the file : /etc/network/interfaces but it doesn't work.

netmask 255.255.255.0
broadcast 192.168.1.0
gateway 192.168.1.254
I was fairly certain that this was verbatim from my previous server which is no longer attached to the network. After hours of fooling around with no success I changed the address to 192.168.1.99 and it worked perfectly. So my question is: why? My old server used 100. Could the router refuse to give a new server the same address or something like that since that address had been taken in the past?

Here's my setup.
MODEM -> router (ISP one don't have access)
from the router it split into 2 connection one to my GW (linux debian) and another to a switch which is connected to a web/email server and the gateway.
My gw use x.x.x.27 and x.x.x.26 (everything I use on these ips is ok)
on the web/email server I have x.x.x.28 29 and 30
With this setup it's ok but I want to eliminate the link to the switch and make it pass thru the GW and i can't manage to get it work!
How do I assign IPv4 and IPv6 static addresses permanently in OpenSUSE 11.2? Currently I am only able to assign either IPv4 or IPv6 static address not both. I cannot find even the interfaces file(/etc/sysconfig/network/interfaces).
View 2 Replies View RelatedI was trying to assign the static IP address of my internet connection to my home server and managed to make a mess of it. I've configured the router to assign it the address every time but when I rebooted everything the server is cut off from the network completely (rather unfortunate with a headless server...). The only file I've edited on the server when trying to do this is /etc/network/interfaces, everything else network related is default. My intention in editing the file was to make the server accept the IP address assigned by the router since the router was already configured to assign the right one. I put in

Could it be the rDNS that is causing this?
Note: this is not a DHCP connection.
I am a developer, not a network admin - sorry if this ia dumb question. I need to test an application on CentOS 55 64 bit. The instalation went fine and initially I let DHCP work its magic. The router IP address ia 192.168.0.1 and all other VM's I have are granted dynamic ip address on this range (i.e. 192.168.0.x). However, the CentOS vm got an IP address that looks like it belongs on a different subnet :192.168.1.1
The VM (vmware desktop) network setting for this VM uses "Bridged: Connected directly to the physical network". I can ping the host (Windows 7 64 bit) and the host can ping it (it been the VM) - but no other computer on the network can see it. To make things easier, I changed the network configuration to use a static IP address. Here are my configuration files:
/etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
HWADDR=00:0C:29:83:4B:A4
ONBOOT=yes

Does a network install assign a pingable ip during installation? I am trying to verify why I get an error during installation that "stage2.img" cannot be found and I'm guessing that since I can *not* ping the static IP I assigned, that the network functionality is not working during the install process. Can anyone confirm if I should be able to ping a system during installation using the assigned static IP?
View 1 Replies View RelatedI'm trying to write a p2p file sharing program using python's built-in libraries. Everything is going well. The only thing is that i'd like to be able to use openssl public and private keys so only a host with the public key could access/decrypt the filesharing. I've gotten these libraries (httplib, basehttpserver, ssl, os) to work using just a pem file containing both the public and private keys but no success with them seperately. Can someone point me in the right direction or offer an alternative? PS, the goal of the project is to create an anonymous, decentralized, secure file sharing program. I want to be able to upload this to sourceforge so everyone can use it, if that's any incentive

PSTN WWW <===========> ADSL Router Firewall <----------------> [eth1 192.168.x.x] Linux Box [eth0 172.16.x.x] <-----> to LAN

1. The VPN is setup and bound to eth1 and eth0 and works well internally
2. IPSec, GRE and PPTP rules have been declared on the router which port map to eth1
However I am still unable to setup a VPN connection to Linux Box I suspect something hasn't been done or I have setup my NATing or IPTables correctly on the linux box.

I will try to explain a bit first about my network typology: I have one cent os 5.5 machine with 2 nics - external one 86.x.x.122 and internal one with 2 IPs: 192.168.1.1 and 89.x.x.121. The ideea is that I have a public subnet (86.x.x.120/29) of IPs which are routable only through 86.x.x.122 so I have a webserver hosted on a different machine with the IP of 89.x.x.122 and GW 89.x.x.121 - everything works perfectly fine, except that I cannot access from the internal network 192.168.1.0 / 24 the so called DMZ (roughly) - the 89.x.x.122.
What really makes me crazy is that I setup the IPtables rules correctly because I can access the webserver from the outside world but I cannot accessit from the internal network...
what I'm missing - why the 192.168.1.0/24 cannot see the 89.x.x.122 machine... What IPtables rules should I add?
