Static IP okay...DHCP no
I have just recently lost communication with several XRAID systems that are set to DHCP. I can ping the ones set to static but can't ping the ones on dhcp. All of my other systems on the network that are set to dhcp are working fine...except my xraids.
Not sure where to start! Help!
I am running RHEL4.
Thanks!
We had a very similar thing happen today to our raid, we only use one controller the upper and set to dhcp, our dhcp serves a static address to the raid 192.168.168.162 and the controller will no longer pull that address - it gets 192.168.168.253 which is actually out of the range allowable - it also shown a different router address 192.168.1.1 rather than 192.168.168.1 we have troubleshot the router it is serving addresses correctly, we have changed the ethernet cables to new ones, we have tried the lower controller and that pulls other addresses - our it guy is stumped - he thinks it might be our switch seems the fans have failed and is running hot, not likely he says, could be our router he is going to replace, says that is also not likely, upgraded firmware to 1.5.1 nothing changed - what else can we do? should we reset the controller? will that erase data on the raid? what could it be

How can I scan my network to determine which PC is using static IP or DHCP?
Hello friends,
I`m using Spiceworks for couple of days alreadyand need some help on this - In another post i saw that via SpiceWorks I can see how many PCs are using DHCP or Static IP (http://community.spiceworks.com/topic/37663-how-can-i-scan-my-network-for-static-ip-s-without-checki...) but is for previous version of the program. Currently I`m running version 7.4.00059.
Can someone point me in the right direction where can I fing this information?

Static vs. DHCP configuration: Arch-specific details
Hi,
I'm a recent Arch convert (after seven years of Slackware, Debian and CentOS). I have a few questions about details that I didn't quite get in the Wiki section.
1) static IP
The sample line in rc.conf is explicit enough, so this one is no problem. On the other hand, there are some diverging hints concerning the configuration in /etc/hosts. Let's say I configured a server with a static IP of 192.168.1.1/255·255.255.0. In that case, is it correct to have an /etc/hosts that looks like this?
127.0.0.1 localhost.localdomain localhost
192.168.1.1 buildbox.localdomain buildbox
Or is it:
127.0.0.1 localhost.localdomain buildbox.localdomain localhost buildbox
2) DHCP
If I configure my Ethernet interface with DHCP, what do I have to put in /etc/hosts? Only the localhost line?Yeah, you don't really need to inject anything into /etc/hosts
I'd say this is partially wrong. When I only keep the default /etc/hosts, I get a warning message when XFCE starts up: it complains that there's no hostname defined.
Finally, I'm using this configuration:
127.0.0.1 buildbox.local buildbox
127.0.0.1 localhost.local localhost
Note: The double 127.0.0.1 is only for better readability.
But I just notice something else, that puzzles me a bit. Here's what ifconfig returns, as expected:
[root@buildbox:~] # ifconfig
eth0 Link encap:Ethernet HWaddr 00:20:ED:B8:E8:EC
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::220:edff:feb8:e8ec/64 Scope:Link

TX packets:52 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:3470 (3.3 Kb) TX bytes:3470 (3.3 Kb)
And here's the network section of my /etc/rc.conf:
# DHCP: Set your interface to "dhcp" (eth0="dhcp")
# Wireless: See network profiles below
eth0="eth0 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255"
INTERFACES=(eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.1.254"
ROUTES=(gateway)
What puzzles me: I didn't define anything localhost-like in rc.conf, and yet it's there. How comes?

Set Up Airport Extreme with Static IPs and DHCP same time
I have Verizon Fios to my Business with 5 Static IP Address. One of them must be assigned to the Airport Extreme Base Station. I have 5 iMacs needing internet connection of which 2 need to use a static ip,( Filemaker Server and my Mac OS X Web Server). I also use 2 iPhones with a custom App accessing that FileMaker Server via the internet too. I want to set up my Airport Extreme Base Station to have those 2 iMacs connected with static ips , which must NEVER CHANGE, via an ethernet cable and all the rest wireless with WiFi. Do to the size of my building I also want another Airport Extreme or Express to just expand the range from the Base Station for the wireless connections only. Looking at the Airport Internet Settings I only see 3 options for Connection Sharing, "Share A Public IP Address", "Distribute a range of IP addresses", "Off (Bridge Mode)". I'm thinking I need to give 1 IP Address to the Base Station, 2 ip addresses to my servers, then 1 ip address to share for my wireless DHCP connections. The additional Airport set to Off(Bridge Mode) to expand the base station. Please advise on how I would set up that base station to do this.
With respect to expanding the base stations range, in the Base stations Wireless Settings I would click to select "Allow this network to be extendeded". Then what settings would I need in the Additional Airport?
Note: Both AirPorts would have to be 802.11n models in order for this to work. The additional AirPort would need to be configured to extend the Extreme. (ref: AirPort Utility > Manual Setup > AirPort > Wireless > Wireless Mode = Extend a wireless network)
Would that NEED to be connected to the base station via ethernet cable or will it pick up the base station wirelessly?
Using the "extend" feature is intended to expand the wireless range of an AirPort with another wirelessly. You would not need to connect them by Ethernet. In this configuration, the additional AirPort would be in bridge mode and will pass through the IP information from the other base station's DHCP service. -
Setting static leases through DHCP (1841)
Interested in how to set up static leases through my DHCP pool on a Cisco 1841.
The DHCP pool is currently set as 14.18.16.0, sharing 14.18.16.20-120 with the submask of 255.255.255.0.
I'd like to have x clients with specific IPs (based on their MAC?), the leases should never expire.
Thanks in advance.You need to capture user MAC address to configure STATIC DHCP Mapping. IMO this is provided for users who want to get the same IP Address but too lazy to hardcode (manually configure in their PC interface) it in their PC :)
Here is the link how to do it http://www.cisco.com/en/US/docs/ios/12_3t/12_3t11/feature/guide/gtdhcpsm.html
Watch out when user change PC, some users (though with NO disability) expect the IP Address to follow them when they change PC :) -
Static IP works, DHCP doesn't with road runner
The boss has a road runner cable modem in his office. He is directed connected from port 2. I ran a wire from port 1 to the downstairs and connected it to a WRT54G. I did this so people downstairs could get wireless access. No one is wire connected to the router.
If I set up the router as DHCP, everyone can see the WRT54G but cannot get internet connectivity. Since we do have a static IP, I set that up in the WRT54G and everyone can connect. That is until the boss uses his machine.
I spoke with Road Runner and they said the cable modem is set up for dynamic IP but we do have a static IP. The best I can decipher is that once the boss signs on the cable modem goes back to dynamic.
But my question is why doesn't the DHCP work? If I unplug the wire from the WRT54G and plug straight into my laptop, it works fines.
Of course Road Runner is blaming the Linksys as the problem.
Thanks
KeithWill you please let me know when you connect 2 computer from the 2 Ports on the Modem are you able to go online from both the Computer at a time.....if yes then you have to configure the Router....if No then You have to connect the Modem to the Internet Port of the Router and configure it accordingly...while configuring make sure you have your computer connected to any one of the 4 ports on the Router.
follow the Steps as Follows:-
Open the set up page of the router by launching an Internet Explorer Browser and type the address bar, 192.168.1.1 and press enter. When it prompts for the username and password, leave the username field empty and provide password as admin and click on ok.
On the main setup page the ""Internet Connection Type"" should be
on ""Obtain IP Automatically - DHCP “. Click on the Save Settings
button.
Now click on the sub tab ""MAC address clone"".
- Click on enable
Click Clone your PC's Mac & click save settings
Check Internet IP on Status page of router ....
If getting Valid IP .... try going online
If not ... power cycle for 4-5 minutes & then again check the Internet IP address by login into the Setup page of the Router....checked the Internet IP Address.... -
Photosmart C4580 on encrypted university network: change static IP to DHCP
My HP Photosmart C4580 All-in-One works beautifully as a wireless printer on small networks such as my home network that goes through one WEP encrypted router. However, neither myself nor the HP support person I spoke with over the phone can get my printer to connect to my HP dv5-1235dx PC (Vista operating system) through my college's wireless network. The network is encrypted (I do not know if it is WEP, WPA, or something else), and does have several visible SSIDs from where my printer is because there are several routers in the building, adding to the complexity of the issue.
The crux of the problem is: I called the school's IT support and they said that I need to change the printer from a static IP to a DHCP but they do not provide support for wireless printers and therefore cannot do this for me. HP support was unable to help me do this when I called them.
Is there a way I can do this if I do not have administrative privileges on the network and obviously did not set up the network? I am not sure whether or not I am allowed to access the router I am closest to to do things such as cycle the power to it.
Thank you!I think you are out of luck without admin access to the network.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

Configuration of Cisco WLC 2504 with Local LAN static IP and DHCP
I want to configure Cisco WLC 2504 with Local LAN static IP and WLC 2504 with DHCP so that APs can be connect with controller.
Currently i am using WLC 2504 with DHCP so can anyone suggest how to do that..Hi Sandeep
The info is correct, if we're using code below 7.3.101.0.
This issue is fixed via the below bug id.
CSCto01390 Unable to ping AP's directly connected to a 2500 controller
check the fix that is updated on 7.4, 7.5 RNE.
http://www.cisco.com/en/US/docs/wireless/controller/release/notes/crn75.html
Note
Directly connected APs are supported only in Local mode.
http://www.cisco.com/en/US/prod/collateral/wireless/ps6302/ps8322/ps11630/data_sheet_c78-645111.html
For quick and easy deployment Access Points can be connected directly to 2504 Wireless LAN Controller via two PoE (Power over Ethernet) ports

How to set VPN server with static IP without DHCP on
I set up a new Mac mini server with OS X 10.9.1 and Server App 3.0.1
My ISP gave me a static bublic IP address.
I have on:
- web server
- mail server
- DNS server
without using DHCP, but now i want to set up L2TP/IPSec VPN server and it requires that i give start IP address of the VPN server.
Can i use VPN server w/out DHCP server on?
If yes, how?
If not, when i turn on the DHCP server, what i have to do with web, mail servers?To run a public VPN server, you need to do the following:
1. Give the gateway either a static external address or a dynamic DNS name. The latter must be a DNS record on a public DNS registrar, not on the server itself. Also in the latter case, you must run a background process to keep the DNS record up to date when your IP address changes.
2. Give the VPN server a static address on the local network, and a hostname that is not in the top-level domain "local" (which is reserved for Bonjour.)
3. Forward external UDP ports 500, 1701, and 4500 (for L2TP) and TCP port 1723 (for PPTP) to the corresponding ports on the VPN server.
If your router is an Apple device, select the Network tab in AirPort Utility and click Network Options. In the sheet that opens, check the box marked
Allow incoming IPSec authentication
if it's not already checked, and save the change.
With a third-party router, there may be a similar setting.

Make cisco 1200 assign a static IP not DHCP
I have given the airport an IP address and installed the card in my laptop. I can connect as far as the airport and it shows me as being connected, but the IP address it assigns isn't configured to go through our router.
Unfortunately the router is managed by another a company and I am unable to change the routing table....so is there anyway you can set the airport to assign a static IP or assign from a range of IP's.
I've looked through the manuals and on this site without any sucess, any help anyone can give me would be great.
Regards
RobJust to add some more....Since cisco's AP can't work like/as DHCP server, it can't assign static/dynamic ip addresses to the wireless clients..So in your case you need fix the router to do routing for your ip address or fix it accordingly..Tejal

i'm trying to figure out how to do this, but i'm coming up perplexed!!
i have a 515 pix that i've been playing with and it has 2 static outisde IP's, i'm trying to get it to establish a VPN conneciton to a DHCP router. if i could do by hostname i would have no issues, but since the PIX wont let me its kind of moot.
is there something i can do with establishing a tunnel? i'd really like to get this goingand actually, would it be better if i did certificates in this situation?

Why are my computers using static insead of DHCP
I have decided to test the Home Hub 3 one last time, before I stick to the home hub 2 till bt infinity is released then get a cable router. Anyway when I add a computer to the network the HH3 seems to be giving them static IPs instead of DHCP and giving gaming consoles DHCP is there anyway to get the static for computers to use DHCP as I cannot find any option in the settings.
When you click on the device name in the 'Devices' list under 'Home Network' does it have the 'IP address assignment' set to Static, or is that this says 'DHCP' but the 'Always use this IP address' is set to Yes?
On my HH3 my laptops both say DHCP, but the 'Always use this IP address' set to Yes and if I change it to No it doesn't stay that way, when I go back to the device list and to the laptop again it's gone back to Yes. I have lots of connection issues as per my thread (http://community.bt.com/t5/BB-Speed-Connection-Issues/HH3-Wireless-N/td-p/232269) from the laptops and losing connection when other devices are turned on.
On my HH2 my laptops both say DHCP, and the 'Always use this IP address' is set to No - I don't have any connection issues with the laptops.
On the HH3 changing the wireless interface type from '802.11 b/g/n (Recommended)' to '802.11 b/g' doesn't make any difference for me - apart from slowing down the laptop connecetion when I can get it to work.
My HH2 is set to '802.11 b/g/n (Recommended)' -
Static ip works dhcp Assigned IP not work
environment:
1. D-link 7100 router provide internet service. DHCP enabled from 192.168.0.140 to 192.168.0.240
2. A DC setup to provide DNS and DHCP, server IP192.168.0.10. DHCP enabled from 192.168.0.20 to 192.168.0.100
3. a normal switch connect the router and DC.
3. Client by default will get IP from DHCP (DC server) .
problem:
some computer got the IP from DHCP server but can't ping through the router, but if you change to manual Ip address it will work, or after restart the router also works.
so any ideas? thanks a lot.
MisnotmI agree it's the DNS address is part of the issue.
Another thing is if the clients are Windows 7 or newer, then you have the NLA to deal with, and even if it may have a correct ipconfig, it may configure the network as unknown.
I've seen this with two separate IT companies that have called me with issues regarding this. If you use the server's DHCP and disable DHCP on the router, as suggested previously in this thread, the issue will disappear.
Here's more on the NLA and how it work.
