Network configuration: fully manual vs. DHCP with manual IP

Are there any OS X Server services (e.g. AFP, DHCP, DNS, OD, LDAP) that specifically require a server's network settings to be manually configured, or can they all get my with just manual IP and the rest of the configuration supplied by DHCP?

Oddly enough, I set up a server with DHCP and manual IP and added its IP to a DHCP subnet. But it was also the DHCP server. It did not accept the DHCP-delivered configuration (e.g. it couldn't find the router).
Is it the case that a DHCP server cannot serve itself with network config information?

Leopard : Network : Unable to use DHCP with manual address.

After installing Leopard on my Macmini (PowerPC 1.42Ghz, 1GB RAM, 80GB HDD), I found my IP address obtains different IP address than Panther and Tiger use. Then I go into System Preferences -> Network -> select Ethernet -> select "Using DHCP with manual address" in the "Configure" combo box, and change the IP address from 192.168.0.8 to 192.168.0.100. Once I hit apply, the network connection never comes back. There is no complaint that another computer is using the 192.168.0.100 IP address. This works if I am using Panther or Tiger on the same computer.
Any help is appreciated.

Setting the DHCP to a number you want to use can be very useful in a busy environment. I usually choose to use numbers that are outside of the range of numbers being controlled by my router (Westell).
Port Forwarding for services like ARD, Azureus, or any server application break when the IP number changes for any reason.
Some routers will not allow numbers outside of a restricted range of numbers that can be set up in the router configuration menu's. In this case, I find out if the router is assigning numbers from the high or low end and make sure I assign numbers at the opposite end of the range.
My Westell router does allow me to use numbers other than the range of 50 numbers it has been told to use for DHCP, but I have also encountered problems when trying this on a wireless connection.

Windows (or other OS) network configuration

Hello all,
I've been asked to develop a Java software that should be able to modify network configuration (IP, mask, ...) of a PC. Is this possible? I don't think so, but, please help me!!
Thank you so much

I have to use Windows, now, but this process could be repeated on Mac or Linux, Solaris, ... not sure yet. But Windows is surely mandatory.
The software I need to develop has to do this things:
- read computer network configuration (IP, mask, gateway, DHCP, ... all the things in IP network connection of Windows);
- save this configuration (let me call it "office configuration") somewhere;
- change the active configuration to apply a "local" or "direct" configuration that will be used to directly connect (with a cross cable) the pc to a network device (Digital Microwave Radio Links Low/Medium Capacity, for Short-Haul PDH Networks I'm working on). Something like IP=10.0.1.x, mask=255.255.255.0 or so and so on for local direct connection;
- do the things on this device (software exists);
- restore office configuration at the end of the software.
Is this possible? Thank you very much.

Network setup 'DHCP with manual address' changes to 'Using DHCP'

I have setup my local network with a manual address and have observed that the setting changes without my doing to simply Using DHCP. I can't get the setup to continue using a manually assigned ip address. Even though I've saved the network settings preferences, they revert to 'Using DHCP'. Any ideas? Thanks in advance.

If you "have setup (your) local network with a manual address," does that mean you have disabled DHCP in your router? If so, then you'd want to configure "manually" in your Sys Prefs > Network.
Or did you mean that you have setup a computer on your local network with a manual address using DHCP? (And that your router has DHCP enabled?)
If the router's DHCP is enabled, many routers will allow you to set aside a subset of IP addresses to the DHCP pool, and the remainder are, by definition, reserved for static addressing. Are you assigning the computer requiring a static IPA (but using DHCP defined gateway and subnet) an address falling within the static address range of your local subnet?
If you can't partition the address space between static IP addresses and DHCP-assigned IP addresses when DHCP is enabled, are you assigning a high-numbered IP address to the computer whose Sys Prefs has DHCP with manual address?

Wireless printing with 2 (or more) printers + manual network configuring

Here's my previous question:
Network configuration: Cable modem (Linksys)-Wired cable router (Linksys)-Airport Extreme Base Station. Wired cable router is used for VOIP phone which is left on 24/7. Base station is shut off when not in use. I had 2 printers, HP multifunction and Samsung color laser printer connected to the Airport via a USB hub, but I could only print from 1. The printer I wanted to use had to be ON and then the Airport turned on to recognize it. So, I purchased a dLink DPR-1260 wireless printer hub. It had to be configured with a Windows operating system, which I did with an XP business laptop. The printer hub had to be configured wired and then the Cat 5 cable removed. The IP address: 10.0.1.2 (dynamic) is what Airport gives whenever anything is plugged into that port. MAC address: 001E589D8035 (which is what the printer hub says on it). SSID is correct. Raw TCP port and LPR/LPD enabled. Re-established Firewall and WPA2 security. Both printers work fine (even scan on HP) wirelessly with Windows XP laptop.
However, neither printer works with either MAC (G5 or iBook) Although they both (HP & Samsung) appear to be ready and start the printing process by downloading percentages of the job.
New info: The IP address of the dLink (DPR-1260) print server is now 10.0.1.3 (Airport is 10.0.1.2) I can connect to 10.0.1.3 thru Safari (or Firefox) and see the device info. I can't configure there. dLink told me to manually configure in network preferences. Their instructions told me to manual change the print server address to 102.168.0.x (x not 10). Then make Appletalk active. When I tried to add the DPR-1260 on the network is said IP Config 10.0.1.3 in use by 00:1e:58:9d:80:35 I guess I need to start over. How can I add the DPR-1260 manually to the network?

xee -
You have two simultaneous problems. Print Server setup, and network-capable CUPS driver required for each printer. Unless either printer is a postscript one, the drivers provided by the manufacturers are Carbon-type, limited to exactly what they programmed it for - probably USB only. That's why Airport Extreme/Express have an advantage over other print servers - Apple has put Mac-to-Mac printer sharing into Extreme/Express, so a USB-only driver works over the network. Other print servers require use of the industry-standard comm protocols LPD or raw port 9100 (=HP Jetdirect) or IPP. Those standard protocols are provided by CUPS and you have to use a CUPS driver with them.
Make it work:
1. Allow the print server to get its IP address just as it has.
2. Install CUPS drivers:

How to manually configure and then use DHCP

I'm having problems with internet connectivity. If I try to configure in Airport Utility, there are two choices - manual or use DHCP. If I allow AU to renew the DCHP lease, I end up with a bad IP address (one of those 169.... ones). If I configure manually and put in the IP address my service provide gave me, then I can input the address, but without the lease renewal, it won't connect. Put in the address in manual, switch to renew the lease, the bad address shows up.
Obviously, since I'm writing this on-line I have connectivity, via the Ethernet port in the back of my iMac, which has the correct IP address I had to type in and is also using DHCP.
So, what's the difference? Why won't Airport line up things just as the Ethernet network will?

It sounds like your cable/DSL modem is not properly recognizing the AirPort Express Base Station (AX). Most of the time this can be remedied by just performing a complete power recycle when changing network configurations ... like when you switch what is connected to the modem.
Try the following, in order, checking for Internet access after each step, until resolved:
1. If the modem has a reset switch, use it to reset the modem. Wait at least 5-10 minutes for the modem to initialize.
2. Remove power from the modem. If it has a backup battery, remove this as well. Wait 5-10 minutes. Replace the battery, and add power back to the modem.
3. Perform a complete power recycle of your network components as follows:
Modem/Router Power Recycling - Quick
o Power-off the modem, AX, & computer(s); Wait at least 5 minutes.
o Power-on the modem; Wait at least 5 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
If this fails to get the modem to "recognize" the Internet router, then try the "Full" version.
Modem/Router Power ReCycling - Full
o Power-off the modem, AX, & computer(s). (Wait at least 30 minutes. If possible, leave the modem off overnight.)
o Power-on the modem; Wait at least 15 minutes.
o Power-on the AX; Wait at least 5 minutes.
o Power-on the computer(s)
4. Contact your ISP to have them perform a "modem reset."

Safari 3.0.4 Slow Loading (Manual Network Configuration)

Hi Everyone,
I'm having problem with Safari loading very slow.
First, due to the need of configuring this MacMini to be shared with a network scanner, the Network IP address need to be configured manually. And since this is not a regularly-used computer, the monitor is being turned off when it's not in used.
The problem comes in when someone try to use Safari. It loads forever! and I mean forever! It seems like it's trying to look for something, but I don't know what!
Does this have anything to do with the manual network configuration and the fact that the screen being turn off?
Interestingly, I also have Firefox installed on this MacMini and it appears to have the same issue.
Any ideas?
Thank you,
Nacintosh520

Hi
Since you have confirm that "screen has no effect on computer or network operation." I'd like to ask you something about this but not related to the problem I'm posting here.
I configured my linksys router to have VNC access, port 5900 open and the IP address of the computer (Mac Pro) that I want to remote access to, and using Chicken of the VNC from a remote computer to access the Mac Pro. From time to time, when I turn off the monitor with the computer still running, I couldn't remotely access the MacPro with Chicken of the VNC; and when I check the MacPro to make sure that it's not turn of any reason, it's ON. This happens several times, so I suspect that turning of the monitor has something to do with the Network! Is my suspicious legit? Or is there anything else I don't know about in this problem?
I doubt that this lag in browsing operation has anything to do with the configuration of the Network Scanner, because the scanning goes through to the MacMini with no problem at the same time that Safari is acting up this way.
The Network scanner is a Kyocera Machine (Copier/Printer/Scanner). They mainly support PC, and our vendor doesn't know much about setting it up on Mac. We're so thankful enough to have it set up in the first place, needless to say setting up "correctly."
Could it be Mac OS X Tiger is still "sleeping" and not fully awake when the monitor is turned off? You know, like power saving feature of some sort. Just a guess.
Thank you,

I'm hooked up to the ethernet using DHCP with manual address. It's running (green) but my internet (Safari, messenger, email) doesn't work! Help!

I'm running an iMac with Mountain Lion. Not only do we do accounting work on this computer with AccountEdge, but the computer functions as a server to another computer in a different state.
Anyway, I set a static IP address (Using DHCP with manual address) on it (to allow for a VPN to the computer in the different state) and it is connected (green dot) - meaning that the other computer in the different state can connect to us via that ethernet line - but for some reason Safari, Messanger, and Apple Email won't work.
But if I switch a dynamic IP (DHCP auto), I can use the internet (Safari, messanger, email), but the computer in the different state can't connect to this computer.
How can I fix this so that the computer in the different state can connect to this computer and that the internet (Safari, messanger, and email) can work at the same time?
Much thanks!

No but if they are using a VPN Tunnel for the connection that restricts all internet traffic over the tunnel. Which means you can't use that same computer to broswe the internet or connect to other computers or devices on your LAN.
I'd need to see the actual setup, router and the IP addresses you are using.
Networking and remote networking is fairly easy when you are in front of the systems you are working on. Doing it over the internet on a forum is almost impossible. Tha is why I suggested you get local help, like the person that originally set it up.

DHCP with manual address doesn't work

My ISP has decided that they won't support static addresses for the
DHCP servers anymore. I'd really like to keep static IP addresses, so
I tried using the "DHCP with manual address." Unfortunately, it
doesn't recognize my Router which is serving DHCP. What's busted here?
Is it Tiger or is it my router (old mansesnse MIH-130).
Any help is appreciated.
thanks.

Comcast I believe is a cable connection.
Interesting, I found that if I continue to manually configure the
TCP/IP settings and just point the DNS to the router (192.168.1.1),
all works perfectly. This worked for 10.4.5, 9.2 and Yellowdog Linux as well.
When you say your isp is no longer using static ip addresses this only affecs your WAN ip. Setup your router to receieve internet via DHCP.
Your LAN ip addresss won't change. You can give all your macs static ip addresses if you like. It does not affect your WAN IP.

ATV2 and Manual Network Configuration Issue

Hi all,
Have 3 ATV2's in the house connected to latest gen TC via 5Ghz WiFi. Works great with one exception. From time to time, one of the ATV's loses the host iTunes library (connected via Home Sharing). If I go the the host and restart itunes - all is well again.
My solution was to try manual IP's for all of the ATV's and the Mac Mini host. Set the Mini to DHCP with manula IP- no problem.
However, when setting the ATV's, all three lose the "Movie" and "TV Shows" menu items as well as Youtube etc.. Meaning, they are obviously not connected to the WAN/Internet. They CAN see the host shared library.
Yes, it would seem my static config is wrong, BUT, I used the numbers already populated when I swtiched from DHCP. Would these numbers not be the ones assigned using DHCP? Would it not be safe to assume that simply assigning these manually would retain the same connectivity?
I switched all but the host mini back to DHCP and all is well again. However, I would like to go with a static set up. Am I missing somehting?
Thanks in advance!
Stuart

Thanks for the reply!
When you say "you also need to assugn adresses from the router" what exactly do you mean?
with exception of Mac Adress Control, I don't see a setting anywhere in Airport Utility that would allow me to assign specific IP's to specific devices...
In the past, simply setting an IP manually on a device would make it static on the network. No intervention on the TC was necessary.
Thanks again,
Stuart

Wireless direct configuration source manual

I have a Photosmart 5520 printer and we changed router and Ithe P address schem. On the first page of the Network configuration page the IP address is correct at10.0.1.10 (DHCP). On the second page under "Wireless Direct" the IP address is 192.168.223.1 and the configuration source is set to Manual. How do I change the IP address for the Wireless Direct IP address so iPrint works again?

The network configuration report can be confusing as it lists information for two different networks in the printer.
The first network is the one that connects to your home network. On your report it is connected with an IP address of 10.0.1.10. I would expect most of your home devices to print over your home network to that IP address.
The second network is the HP Direct Print network. It allows devices to directly connect to the printer to print. It's IP address shows as 192.168.223.1 If you connect a device directly to the printer it will see the printer at that IP address.
Most of your comuting devices will connect to your home network and print through it. There should be no reason to change the HP Direct Print IP address. I'm not sure it can be changed.
Now to resolve the printing problem. iPrint might need to rediscover the printer. You may need to treat the printer as a new device and delete the old connection. Hopefully this will solve the issue.
If not - I'm guessing that there is a routing issue with the new router. The best way to resolve that would be to power off all the computing devices, power cycle the new router, turn on the printer and wait for the blue wireless light to turn on and stay lit, then power up all the other wireless devices.
The idea is to let each device relearn the network as it comes up. If there is still a problem after doing this there might be a configuration issue on the router that is not letting the network devices see the printer.
If neither of the above help there might be an problem with the configuration of the new router. It's configuration might not allow the wireless devices to see the printer. Let us know and we will work through that. To troubleshoot a router configuration we will need the brand and model of the router.
Good Luck!

Best wireless network configuration with my hardware

I have a rather large property and over the last year or so I have acquired the following hardware. Up until now I have been extending my network wirelessly to get through coverage. However with the recent addition of a Time Capsule and the addition of AT&T U-Verse, I decided it was time optimize my network configuration
The Hardware:
• 1 AT&T Residential Gateway (With WiFi)
• 1 Airport time Capsule
• 2 Airport Extreme 802.11n (Gigabit Ethernet)
• 1 Airport Extreme 802.11n (Fast Ethernet)
• 1 Airport Express 802.11n (used mostly for printers)
The Computers:
• Mac Pro 8 core 2.8Ghz
• Mac Mini Core Duo 1.83Ghz
• Macbook Air Core 2 Duo 1.8 Ghz
• Lenovo T60p (with 802.11n)
• Ipod Touch
The slowest system is the Mac Mini with it's 802.11g however it is close enough to the TC / Residential gateway to wire into the network. All the other systems need to take advantage of the Wifi and have the ability to use the 802.11n speed. I'm not too worried about the ipod touch...
So I know I am reaching a point of diminished returns by constantly extending my wireless connection. Now, would it be beneficial to set the TC as kind of my main Wif access point and use eithernet to connect my Airport Extremes to extend my network?
I have the built in 802.11g of my AT&T RG disabled right now. I could create a 2nd network to allow the connection of my mini and iPog touch. but for the most part i would prefer to leave it disabled.
One thing to take into consideration. Due to the nature of AT&T U-Verse and the connection from the AT&T RG and the TC/AP Extreme bust be in bridge mode giving DHCP control to the AT&T RG.
Whew. Any thoughts?
Message was edited by: Vermifuge

Ethernet as many routers as possible. Place secondary routers in bridge mode. Separate the N devices to a router (TC) from N+B/G devices should go to the secondary routers. Once done set wireless to create their own network. All N computers to N router ie TC and the remainder to which ever secondary router you prefer.

IPX not working with new Network Configuration

Here is my situation. I have been engaged with a customer that had the following equipment.
1x 3640 Router running IOS c3640-d-mz.121-3a.T1
1x 3550 L3 Switch running IOS 12.1.15 EMI
8 x 3548XL L2 Switches running IOS c3500xl-c3h2s-mz.120-5.WC13.bin
When I was asked to look at the network they were experiencing slow LAN speeds (10.8MB file between two LAN hosts around 12 minutes). This network consisted of 10 Class C networks 10.5.60.x - 10.5.69.x, these networks were based on the 3560 split between two interfaces. Odd ranges on FE 0/0 and Even on FE0/1. The router was acting as a stub router on a T1 from the clients core network provider. This core provider has IPX services that my client has to be able to use. Under the old design there was no VLAN structure and basic network services such as DHCP barely worked.
Now the network is configured with the 3640 router as the edge routing device and the 3550-48-EMI is configured as the LAN routing devices. I have split the 10.5.60.x range in two using the lower segment for VLAN 60 and using the upper range as the communication network between FE 0/48 on the 3550 (ip addr 10.5.60.130 255.255.255.128) and FE 0/0 on 3640 (ip addr 10.5.60.131 255.255.255.128), these interfaces are connected via an ISL Trunk. Each VLAN is set at the 3550 with the gateway of 10.5.x.1. Each of the 8 3548XL switches is configured with all of the VLANS and are linked to the 3550 via 100 BaseT and 1000BaseT interfaces configured as dot1q trunks. Multicast routing is enabled on the 3550 to allow services like MDNS and Imaging to occur across VLANS.
With all this said IPX is not working. My 3640 edge router is still seeing all of its upstream IPX servers and networks. This router also sees the local IPX network as connected out of FE 0/0, based on this config setting (ipx network 1368023) FE 0/0. I'm guessing that this piece of the puzzle is based on my L3 changes on the LAN. But I just am not able to wrap my head around what it is. Any help that could be offered concerning this issue would be greatly appreciated.
Whatever the solution is it needs to happen with no more hardware and this new structure has to stay in place. I have been able to fix all ip network services such as DHCP and the customer reports a 1013% speed increase from the point when I first arrived. The 10.8 MB file mentioned above now transfers in about 8 to 10 seconds across the LAN.
Again Thanks.

I was pretty sure of that. Is there anyway to tag the IPX traffic to a VLAN from the 3600 as described in http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t1/ipx_vlan.htm Which so far hasnt worked...
Or is there a way that I can simply use broadcasts at a L2 level to accomplish connectivity? This was working like a charm under the bad network configuration that was purely L2 and 10 subnets drapped accross two router interfaces. It seems like there should be some sort of simple fix I'm missing.
Otherwise is there a way to have the VLAN clients talk up to the 3600 in order to get IPX information? In the end this is a short term fix. 3 weeks from now the IPX app is being replaced by and IP app. But I need it for 3 more weeks.
Thanks,
Josh
