Networking :: Set An Static Ipaddress On Network-scripts But Dynamic Ip Shows On Ifconfig?
Jan 27, 2010
I recently installed fedora 12 in my server where I had a page published in my local net by tomcat, and I was looking on the Internet how to set up an static ip address and this is what I did
then I can access via ssh by two addresses the one I got from dhcp (10.17.148.223) and the static one (10.17.148.26) I put ifconfig and and 10.17.148.223 appear on eth0 I restart my server and I just can access from 10.17.148.223 I have to put
ifdown eth0
ifup eth0
Again...to access by my static ip, y can access my page by its dns on my server, but I cant access from other computer...so, I guess when my static adress appears on ifconfig I would be able to access my page from other computer...
I messed up my Network Connections when I put a different NIC in my computer. Now I just went back to using the old NIC. It shows up in ifconfig, but the GUI Network Connections is blank. When I manually Add the connection back to the GUI Network Connections, the settings are not reflected when doing ifconfig.For example, I change the IP address for eth0 in GUI Network Connections, save the settings,
I want to restrict the Visitors to my Webserver whom i want to give access But the persons whom i want to give access. have Dynamic IP. I want to use DynDNS and update IP address of person. Based on the Hostname Pointing to Dynamic address of person.
in my iptables script I define the environment like this:
Code:
# ENVIRONMENT # Private interface IF_PRV=eth1
[code].....
if I give the IF_PUB interface the DYNAMIC IPaddress assigned by my ISP how can I define it in IP_PUB and also the NET_PUB so I can then use it for the firewall rules.
I'm on Fedora core 14 linux. and I'm online with the HSPDA modem. My modem is /dev/ttyUSB0 and when it's dialed it creates the interface /dev/ppp0 , My question is when I hit ifcofig it shows two IP addresses in the ppp0 interface.
Code:
[nature@localhost ~]$ ifconfig eth0 Link encap:Ethernet HWaddr 20:6A:8A:12:CF:53 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0
[code]....
when I get the routing table, the gateway is setten to the 10.64.64.64 and when I look my Ip address global I found it's 175.157.64.119.
My wireless usb will not attempt to connect to my AP even though it shows in ifconfig and iwconfig:further information which i believe may helplspci -v

where are the interface configurations (set by ifconfig, not the static ones) stored? I'm asking because I'm trying to understand, more broadly, the order of IP address lookup. If I ping the local machine (localhost, or one of the interfaces) no messages get sent out (at least according to wireshark), so some local lookup must be taking place.

Note: the Code/Design/Security projects pages (A,B,C,D...) will be at start around 35 pages, and will grow. My index.php is something like this: PHP Code: .....
What I would like to know is how to build the content (the home-main.php)? Do it dynamically based on a link something like this index.php?page=coding_b, and put in the index.php page a number of 35 if/else statements to cover all the project pages or ... static, creating every page for the projects menu when I create the menu? I check if a page 'pro-co-a.php' exists, if not I create it based on some template and do the query to get the content from db or? How to organize the pages, if using static page?
Centos el5xen x86_64 in a company network, novell-netware, Static IP I have several issues with the Xen network configuration. This configuration worked before, and was maded by a other personn with a higher level in centos and network . I'm trying to re-install xen in bridging mode.
1) The dom0 ping in the company network, but can't acess to the Internet.
I de-activated firewall, iptables and SE-Linux for the test.
the ifconfig-a command return eth0 lo sit0 (IPV6 encapsuled in IPV4) vif0 vnet0 but no Peth0 Physical device
I have an old program that kind of depends on older dynamic libraries. They tend to get upgraded easily with distro's updates. I figured that there would be a script with using ldd that would gather the libs needed and create one bigger, statically linked application that wouldn't break so easily. If I could do this, a lot of older KDE libraries could be removed from my system and easen my life.
My distribution of choice is gentoo, but I'm looking for a general solution that doesn't depend on rebuilding anything. If it runs with libs on their path, I'm sure it can be made run with libs somewhere else!
got a VPS and for testing purposes a homeserver with apache running. what two tools would i need to redirect my static ip to my dynamic one?
the traffic shall all go through the dynamic one. i've got a domain name registered with the VPS also. nameservers are configured.
is there any setup required on my local (dynamic ip) apache settings for using the name? and if i stop the service, will it still work? do i have to setup a webserver on the VPS for it? none running yet.
I am currently looking for tools for static/dynamic code analysis for embedded Linux system development (both device driver and user space apps). We will use Eclipse IDE and C++ lanuage. I hope the tools are easy-to-use, reliable, popular, better with good supports, and not-too-expensive. I already find a list of tools at WiKi, however, I don't have time to try them all. Could anyboy please recommend me a few? If you can tell me briefly about their pros and cons, that will be the bet.
I just installed Fedora 13 from the Live CD. FIrst off I read the guide and the first step doesn't even work for me. System>Administration>Network does not exist. If I go to System then Preferences I see a Network Manager but it looks nothing like what these screen shots look like. [url]
No wireless card show up in the wireless tab of Network Manager. How can I fix this since my card is listed in ifconfig and iwconfig. Wifi card is a Zonet zew2500p
I have got Ubuntu 10.10 on a Dell Inspiron Laptop. Can't get anywhere with wireless network. Tried a few bits of poking it blindly with a stick:
matthew@ubuntu:~$ lshw -C network Warning: you should run this program as super-user. *-network Description: Network controller Product: BCM4312 802.11b/g LP-PHY Vendor: Broadcom Corporation Physical id: 0 Bus info: pci@0000:0c:00.0 Version: 01 Width: 64 bits Clock: 33MHz Capabilities: bus_master cap_list Configuration: driver=b43-pci-bridge latency=0 Resources: irq:17 memory:f69fc000-f69fffff *-network .....
I reckon *-network DISABLED is a problem, I tried sudo ifconfig wlan0 up but that didn't work. The output of that and lspci are on the ubuntu side of my machine. I have also tried pressing my wireless on/off key (F2) but that doesn't work either.

I have installed CentOS. I have two ethernet card (one onboard and one PCI). I am able to set ip for realtek ethernet card and my atheros(on board) is not shown in network ifconfig shows only one ethernet card (PCI) hen i gave the command lspci i got the following output
In 8.04 I can use the network manager app to set a static IP.
In 8.1 the network manager doesn't seem to work. I tried many different permutations of settings and got nowhere. Even though I put in IP subnet and gateway it still does the DHCP config.
So I added lines to my /etc/networking/interfaces file like this:
auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.100 netmask 255.255.255.0 gateway 192.168.0.1
I then either reboot or do this: sudo /etc/init.d/networking restart
This made the network manager icon in the top panel vanish. An ifconfig showed that those settings are in place but DNS doesn't seem to be working. I can ping other hosts on my network by IP but not www.yahoo.com etc.
I even read the man, that's how desperate I got! (a config like the above seems to work on my 8.04 machine except that the auto eth0 appears at the end of the file.)
I didn't see how to set the DNS server(s), unless I was in the wrong man.
I am trying to secure my LAN a little by doing static arp entries. But I am not sure how to go about doing this... I have a gateway, and I have a seperate box that runs dhcpd. I would like to assign every machine an ip and only allow it to use that ip, therefore static dhcp entries, and static arp entries on the gateway.
1. But how do I prevent someone from picking an ip that nobody is using and assigning it manually?
2. I assigned a static arp entry by doing arp -i br0 -s 2.2.2.35 00:1F:E1:CC:2E:46, how do I remove it now? I used arp -d but now it just says:
? (2.2.2.84) at <incomplete> on br0
3. I would also like each machine to have a hostname/dns.. like machinex.local, where I can do forward and reverse dns lookups, how do I config this?
4. I know static arp can be fooled if someone just clones an allow mac.. is there anything else that I could use that is more secure for wired lan?
5. I have my gateway running rflow sending all data to ntop running on my dhcp box.. Ntop is kinda cryptic, is there anything easier to use? or something that is better in features? I would like to see how much bandwidth each local ip is using and possibly what protocols, like ntop already shows.
I have a fresh install of Centos 5.x and I'm having issues on setting up the network...i know i have to edit/etc/sysconfig/network-script/ifcfg-eth0 and create an ifcfg-eth0:0 right?im just having issues getting everything setup correctly.my network setup:Router IP: 192.168.2.1IPs on network: 192.168.2.xNetmask: 255.255.255.0
I'm setting up a home webserver with Ubuntu 10.10 and want to configure the interface to static. I'm using a router, which is setup and working correctly. I have been using linux workstation with dhcp for some time.
I've edited my interfaces file to reflect the parameters for setting static ip, with the exception of 'network'. No matter what I put into this setting, it causes me to loose connectivity to the outside world. I've tried to put my router IP, and my IP set by my provider. What should the 'network' value be?
At this time, my 'interfaces' files only includes the following and has connectivity out to the internet:
Code:
Do I need the 'network' settings as shown in every tutorial (but never explained)?
I'm having strange difficulties in setting a static ip for my CentOS 5.4 installation. If I use DHCP everything is fine, but with a static ip I have no network connectivity. I have done this many times with RedHat/Fedora/Ubuntu etc. with no problems and now I have no idea what I'm missing or doing wrong. I have tried to set ip as 192.168.1.20 (anything below .100 will do). GW is 192.168.1.1 and NM is 255.255.255.0. This is all I have had to use with other distros, but now when I set these I cannot even access my routers admin page or ping it (192.168.1.1). (I just did this with Vista on my other machine and all worked fine).
I'm encountering a strange problem. I need to open and forward all UDP and TCP ports related to VoIPtelephony (5000:32000) in the Suse 11.1 server that's acting as router/firewall in our setup. The ports must redirect to a Asterisk server in the local network. (This server has the IP adress 192.168.0.3)I've opened ports in Yast (Firewall>Ports>Advanced) and putted in some masquerading rulesirewall>Masquerading):0/0,192.168.0.3,tcp,5000:31000,5000:310000/0,192.168.0.3,udp,5000:31000,5000:31000when I do a nmap localhost I get:Starting Nmap 4.75 at 2010-01-08 16:52 CETInteresting ports on localhost (127.0.0.1):

I need static networking to be functional on F14 to try freeipa....the problem I have is I am unable to get eth0 to start. Knowing the software it has to be eth0 or it will likely not work... The guest is in a RHEV6svr environment... So I have disabled NetworkManager and enabled networ and set manula settings in ifcfg-eth0 incl the hware address but eth0 wont start on boot....
next I tried setting a e1000 network card after the hypervisor default didnt work, only to find that this doesnt work either. The MAC addresses are changing as I try and fault find a dead DNS client issue (yet another F14 issue but lets not go there yet, it could be RHEV's "funky" NATing setup)....so I suspect F14 has got its knickers in a twist over the MAC for ETH0....I keep changing it and I suspect it cant keep up.....so I need to disable the automatic function(s), if there is one....
So somewhere down in the code there is probably a line saying eth0= <mac address> but despite greping I cant find that.....or not something that I edit and it then works.... I have tried the gui tools and command line tools and I still have no network..... So what would be a totally CLI process to fix this automated crap? ie stop F14 pointing at the wrong MAC for eth0?
I want my Ubuntu desktop to have a static ip-address, i have altered the interfaces file to the below and also filled the info regarding my wireless network card but still every time I reboot the desktop gets the ip 10.42.43.1, HOW is that possible???
I use a apple time capsule router, I want my desktop to run a apache server thats why I need the static ip. I also want the static ip to be set on the wireless network interface. I have an old laptop with an internal Intel pro 2200 card so there should not be a driver problem.
This i my interfaces config code...
To be on the sure side to get this to work I have configured my router(DHCP) to give my wireless-HWaddress the ip of 10.0.1.15, STILL the ubuntu desktop starts with the false address above.
I wanted to have a static local IP on my server,But on my 192*.168.1.1, there's a place where ic an see all devices, and before, the displayed name was "STASH" and with the update i put, it'S now "--", but i'd like to keep my old one..
I want to set up a static IP on my laptop that connects via wireless to my home network. I have 11.04 installed on my laptop. When I try to use the manual IPv4 setting in the network manager the save option gets greyed out. I tried to edit the /etc/network/interfaces file but all the examples I could find on the net refer to eth0. I tried replacing this with wlan0 but this did not work. I tried installing wicd but I kept getting "Bad Password" errors even though I know the password is correct. A number of people recommended uninstalling network manager to get wicd to work but many other posts said that uninstalling network manager didn't help so I didn't want to go ahead and uninstall unnecessarily. Besides I figure if Ubuntu is distributed with network manager there must be a reason for having it. So what do I do to get a static IP address for the client on a wireless connection?
1. I went to network manager and selected "Connection Information" On the information window I saw the following:
IPv4 IP Address: 192.168.1.6 (This is the item I wanted to change and make static) Broadcast Address: 192.168.1.255 Subnet Mask: 255.255.255.0
[code].....
2. I went to network manager and selected "Edit Connections" 3. I selected the wireless tab and then the wireless network I wanted to edit 4. I clicked on the edit button and then I clicked on the IPv4 settings tab. 5. I changed method from Automatic (DHCP) to Manual
