DNS and Static IP Address Question on Solaris v10 X86

I�ve recently installed Solaris v10 X86 and have two questions. The system is a Dell E521 with 4GB RAM and 1GB SysKonnect NIC, and internet is provided via a cable modem, that�s plugged into a Netgear router, and the Solaris 10 box is plugged into the Netgear router via a CAT5 ethernet cable.
1. I can connect to my router login page using the following URL:
http://192.168.1.1/start.htm and I can also connect to various web pages such as yahoo, if I first "ping yahoo.com" (on another machine that�s internet enabled) and then plug the web site�s ip address into the Solaris/Mozilla browser. So it appears that I haven�t been successful at pointing the Solaris x86 at a DNS server to resolve the DNS name.
2. I've purchased a commercially available software package and it requires a static ip address for this Solaris x86 server. If the ip address changes, it�ll stop working by design and require that I reacquire the license file. When connecting through this Netgear router, how do I lock this Solaris v10 x86 server into a specific ip address? (the ip address floats presently when cycling my PC�s on/off) presently, and assume the Solaris box will too, usually through an ip range of 192.168.1.<1 through 5>

pci1148,5021, instance #0 (driver name: skge)
pci1028,1ed
pci1022,1100
The NIC is a SysKonnect 9821 1GB Ethernet card. The drivers in Solaris 10 were apparently very old and didn't install drivers or configure/plumb when I installed Solaris 10, so I downloaded the
latest drivers (hard to find!), followed the instructions and got the NIC drivers installed and then plumbed.
My router's ip address appears to be 192.168.1.1 and in one of the articles I've read, there is a recommendation to create a file (touch) within /etc named defaultrouter and enter the router's ip address. I did this, and the file now contains:
192.168.1.1
I also read where another file called resolv.conf needed to be pointed to a DNS server, which in this case, according to my Netgear router, and according to ipconfig/all on another WinBox on the same network, also shows the same 192.168.1.1 address for the DNS, so I created that file too (wasn't there) and it contains:
nameserver 192.168.1.1
There is a host name file called hostname.skge0 and it contains one line:
INTHOST
There is a hosts file, and it contains:
127.0.0.1 localhost loghost homex86
192.168.1.3 INTHOST
There is a netmasks file, and other than the commented out lines, it appears to contain one relevant line:
192.168.1.0 255.255.255.0
There is a nsswitch.conf file and other than the commented out lines, it contains:

Finally, I've also seen some advice using the folling command (and I tried it):
"route add default 192.168.1.1" as an alternative method of setting up route table
The only other command I've tried is:
"ifconfig skge0 192.168.1.1 netmask 255.255.255.0 up" but I suspect that was redundant as the plumb command I used to get the NIC functioning earlier probably already provided what was needed.
Finally, on this small network, I ran an ipconfig/all on a Windows based PC, to see what network settings were reported through the wireless connection, and this is an excerpt of that information:

HH5 and static IP address question

I've been trying to set up static addresses for my devices and for some weird reason, when trying to set an address for one PC, the HH tells me the following:
The IP address entered conflicts with a device using the same IP address on your home network.
Please enter a different IP address.
Ok, seems fairly self-explanatory but after looking through the devices and dhcp table, it appears that no other devices have that IP address. How can I free up the address in question if I'm unable to locate what device has been assigned it please? It doesn't respond to pinging.
Thanks.
P.S - Can remember my previous frustrations with earlier models of the HH. Can anyone recommend a decent third party router that works well with BT Infinity please?

From what I can remember (I haven't used a Home hub in eons) the Home Hub's DHCP range is 192.168.1.64-192.168.1.253 (.254 is used for the router itself), so in order to use static IPs on your LAN, you would need to use 192.168.1.1-192.168.1.63 for your devices.
Don't forget that the subnet mask would be 255.255.255.0
I hope this info helps.

Weird DNS and GATEWAY IP Address

iPad 1 and iPad 2, join wireless network, pulls 192.168.1.199 for a DNS and GATEWAY address, force a STATIC (manual) of 192.168.1.1 works, revert back to DHCP, keeps 192.168.1.1 until offsite and attempt to reconnect.
Tried Renew Lease, still pulls 192.168.1.199, have to always force 1.1 and revert back to DHCP afterwards.
Router has static IP (Cablevision), 255.255.255.248 Subnet with OPEN-DNS (208.67.222.222 and 208.67.220.220) Even if I use Cablevision, Google, Verizon DNS, always pulls a 1.199 IP for GW and DNS.
Tried 3 different routers, still weird.
Any ideas?

HH4 and static IP addresses on home network

I want to assign a static IP outside the DHCP range to a server on my home network. I know I've done this in the past as I already have another server on the network which the HH4 recognises as having a static IP (and not in the DHCP range) but I can't for the life of me remember how to do it now.
I do recall that it wasn't obvious last time, but I've looked repeatedly through the HH config options and can't find it. The only place that looks likely is the Device Information page, where if "IP address assignment" is DHCP then you can select "Always use this IP address" and type an IP address, but only addresses within the DHCP range are accepted (this is reasonable). But there seems no way to provide a non-DHCP address.
I've read elsewhere that I should allocate the static IP on the device itself, but this doesn't work - while the device is able to connect to the LAN and can ping/can be pinged by other devices, the HH doesn't recognise the device and it's unable to connect to the internet.
I've constantly been frustrated by the non-standard interface of the HH4, and the fact that BT will provide little information on how to configure it (no manual is available). I called BT just hours ago to ask their tech support the same question I'm asking here, and their response was that "they don't have that information". When I said I was amazed that they don't know how to support their own hardware, they replied that it came ready configured and I shouldn't need to change it. Unbelievable. I was invited to subscribe to their tech expert support for £8 per month to get the answer, so I suspect that the claimed ignorance is just a revenue-earning opportunity.
Anyhow, any help will be very welcome.
Solved!

Hmm, as far as I'm concerned the only 'true' static address is one configured on the device itself. Anything else is a non-changing dynamic address which is still at the mercy of the router dishing it out correctly.
That's a fair point. Perhaps I'm not used to routers (or just never used the feature) that allow "sticky" allocations within the DHCP range. So I see (saw?) DHCP and non-DHCP addresses as different.
However, I have to admit to feel a bit stupid at this point. I've just looked at the HH display and now I can see my device in all its static glory! This is after a number of days of testing and experimentation and getting nowhere (and before you ask, yes, regular refreshing). It's puzzling - perhaps it takes time for the HH to pick up a static allocation and I just didn't give it long enough.
So it does appear to be working now. I can confirm that your advice of just defining the address on the device is the way to go, and eventually the HH will recognise it.
Thanks to all for your patience!

Port Forwarding and Static IP addresses

Netcomm NB1300 router and Airport Express.
I want to use and old G3 mac running 10.3.9 as a server for HTTP and FTP. The Mac is currently connected via Airport but I can connect it via Ethernet if necessary.
I understand that I will have to activate Port Forwarding on my Router with Ports 21 and 80 to allow external Internet access to the G3. I will also have to configure DHCP Manually for a Static IP address and probably link up with a Free DNS service to maintain reliable access to the G3.
I have other computers on the network, two Macs (Ethernet / 10.3.9 & Airport 10.4.11) and two PC's (one with Vista, one with XP / both on Airport). Only one of the extra Macs is connected via ethernet, the rest are connected via Airport.
Will I have to assign Static IP addresses to all the computers or just the one I want to use as a server?
And also, can anyone tell me about Port Forwarding via Port 22 to give more security from external observation/attacks? I know nothing about this security measure.
Thanks in advance.
Christo.

I am now assuming I will be able to access the 'server' from an external location. Very optimistic! But I can't test that for a couple of days.
Ah, but you've given up too soon! You can access your web server from outside your network real easy: you just need to find an external client you can point back to your site. I like to use the W4C validator to do that. It has the happy side effect of also telling you if your web page markup is valid. So you'd point your browser to the validator page:
http://validator.w3.org/
I like to choose "More Options" and tell it to show the page source. That way I can also verify that it's seeing the page I want it to see.
If I disconnect the iBook from Ethernet, can it still be accessible from an external location if it is connected to the Router via Airport, or do I have do so something like Port Forwarding with my Airport Express as well? Note the iBook can still connect to the Internet via Airport.
It would depend on how your Airport is set up. I think there are a couple of ways to set them up. One is to make the Airport a DHCP server, which would make the wireless network essentially a separate network. In that case, you'd have to forward throught the Airport, too.
My wireless network, though, is set up to bridge, so it's all one network. In that case, all I'd have to do to forward wirelessly to a client would be to set up the forward on the main router.
Being that persons other than myself will be accessing the iBook via FTP, do I give them the user account password of the Mac, or can I set a password in the Router or something else?
Also, when accessing the iBook on my local network using Cyberduck, I can see the entire directory of the iBook's user account. Is there a way to limit access to just one folder, such as the Public folder, or a self-designated folder?
Unfortunately, I don't know anything about setting up FTP. I would suggest that you look into maybe making an account on the iBook specifically for the FTP user and only give out that username and password. You might want to poke around in the Networking and the Web and Unix discussions in the Mac OS X Technologies area. I've seen a number of posts there about setting up FTP, and you might be able to find your answers there.

Time Capsule connected to internet via ethernet and static IP address

Hi! I'm at my wits end and getting no help from my IT department. I want to use my Time Capsule to create a wireless network within my office. I can directly connect my TC to the internet via ethernet and an assigned static IP address. However, doing so I'm unable to connect to the internet using the created wireless network on my laptop. I've tried using the bridge option for sharing as well as the "sharing an IP address" and neither configuration is working. any thoughts?

I have the same setup; my ISP uses static IP only. No probs configuring a LinkSys router but with TC it's not obvious where to plug in the info. Can't ping the TC router via IP address to setup directly like the LinkSys which would be simple. Is the out of box router address really 10.0.1.1 on the LAN side? I want to use the 192.168 sequence and have changed it but still no success as I can't determine where to put the static IP! Can you give me something specific? By the way, it works fine thru the LinkSys router in Bridge mode.
Thanks,

Setting hostname,domainname and static IP address

Hi,
I have an issue regarding hostname and domainname on Oracle Linux 5.4.
I followed the steps given on this link for Oracle Linux 5.4 installation.
http://www.oracle-base.com/articles/linux/OracleEnterpriseLinux5Installation.php
As per the snapshots and guidelines given on this link,I should have been asked to configure network interface.
But It didn't show me the screens shown in steps 16,17 and 18 where I could have entered hostname,domainname,IP etc.
And when I checked after installation,it showed me
hostname
localhost.localdomain
and
domainname
(none)
That's because it took DHCP network configuration automatically(Correct me if i am wrong!!).
Although I am going to turn it's currnet DHCP assigneed IP into static IP.
Now,as I am going to have to install Oracle E-Business suite on this platform,I must have hostname,domainname and IP set properly.
Please guide me how I can set these three things(hostname,domainname and IP) permenantly.
Also should I turn its current DHCP IP into static IP before changing hostname and domainname or after it?
Thanks,
Rushi

HttpServlet and multiple URL addresses question

Hi!
I've created a HttpServlet using the New... wizard (BTW, my web.xml file wasn't updated so I had to do it manually). I've implemented doGet and doPost methods in this class. I specified an url-pattern in web.xml as <url-pattern>/httpservlet/*</url-pattern>.
If I'd like more than one URL address inside this servlet, what do I need to do? I'd like to have an URL that only supports POST method. This is something I have now as my doGet method looks like this:
    response.setContentType(CONTENT_TYPE);
    PrintWriter out = response.getWriter();
    out.println("<html>");
    out.println("<head><title>HttpServlet</title></head>");
    out.println("<body>");
    out.println("<p>GET method is not supported. Please use POST method for XML messages.</p>");
    out.println("</body></html>");
    out.close();Now I'd like another URL that supports only GET method and has a parameter. This address will be used for downloading some PDF documents. Do I need another HTTP server? Do I have to create a jspx file (how do I 'tell' it that is in this servlet)? Are there other options?
Thank you in advance for any suggestions.
BB

Hi,
you can create another servlet mapping in web.xml for the same Servlet. However, note that the access path doesn't determine the access method. Your servlet still need to check if it was called from a GET or POST request

Cant connect Solaris 10 with internet with a static ip address

Hi, Guys:
I just installed a Solaris 10 on a PC on my company's network.
The box can get an IP address from my company's DHCP server if I use "ifconfig skge0 dhcp", and it can connect to Internet without any problem.
I can ping the gateway router, dns server, and browse the websites. The gateway router and dns server have different ip addresses.
However, when I assigned a valid static IP address to the solaris 10 box and rebooted the box, it cannot connect to the internet anymore.
It cannot ping the gateway router, dns server. It can only ping itself.
If I do ifconfig -a, I can see the static ip address I assigned to it.
Here is how I assigned static ip address to the box:
I add the static ip address to /etc/hosts, /etc/hostname.skge0, /etc/ipnodes files and rebooted the solaris 10.
I have added "hosts files dns" in the /etc/nsswitch file.
I have /etc/defaultrouter with the valid gateway router's ip address.
Can anyone tell me what went wrong here? Why I cannot connect to the internet when I assigned a static ip address to it?
Please feel free to let me know if you need any output data.
Thanks!
richard

just some quick thoughts:
are you certain that you are configuring the correct netmask in your manual config? If you cannot ping hosts on the same subnet, nor are you able able to ping the default router (which needs to be on the same subnet as your system), that comes to mind.
was your static addressing info provided by your network administrator or did you guess? assuming that the static info is on the same subnet as the DHCP provided info (a /big/ assumption), the "ifconfig -a " info from the DHCP configuration will show the netmask.

EA6700 - Maximum Static IP Addresses

Is there a limit on the number of Static IP Addresses on the EA6700? There are currently three open entries called Static DNS 1, 2, 3. I am using all three, and would like to add a fourth for the WAP300N Access Point. Is there a way to add a fourth Static IP Address? Thanks

Thanks for the advice. I thought I knew what I was doing by "reserving" IP addresses using the DNS entry. Now that I found and read the User Guide, I understand how to “reserve” these devices. I still need to find the Linksys valid ranges for static vs dynamic on the EA6700. I don't see this info in the user guide. Or does it matter?
Don't I just go to the DHCP Reseration Table, select the devices, and click on Add DHCP Reservation? This reserves whatever IP address was dynamically assigned to it. Currentlu on the DHCP panel, the Start IP address is 192.168.1.100, number of users is 50, so the range is 192.168.1.100 - 149. I will clear out the DNS entries. I may just reset the router and start over. If the range begins at 192.168.1.100, then I'll use 192.168.1.2-99 as static addresses and 192.168.1.100-150 for dynamic IP addresses.
Is the default Release Time of 1440 (24 hours) adequate?
Should I keep dynamic and static IP address separated in different ranges as in your example? .
We have 24 devices on our home network including laptops, desktops, printers, iPads, iPhones, NAS, etc.
I planned on setting static IP addresses for my primary desktop (where I manage the network), network printers, IP cameras, WAP300N Access Point, Seagate BlackArmor 440 NAS, Honeywell 6280 Tuxedo keypad, and Xbox 1.

8-way SMP with Solaris 8 x86

We're pondering the purchase of two 8CPU Intel boxes to run Oracle Parallel server. Since Oracle Parallel Server has not been ported to Linux, we'll need to run Solaris x86.
Now, my question: Does Solaris 8 x86 support 8 CPUs? I called Sun and was told no and e-mailed them and was told yes. So, I got two different answers. Can anyone point me to a definative answer?
Thanks,
Mike

Mike, Oracle Parallel server is not supported on Intel Solaris. ;-) check with Oracle (this should be true for 8.1.6 and maybe also 8.1.5). I do not believe you want to turn to Oracle7 in these modern days...

How to setup a static ip address and DNS on airport extreme using the iOS Airport Utility?

I am at a location that only has wired ethernet. The ethernet connection has a specific Static IP address, subnet, gateway, and DNS setting. I cannot seem to find how to enter DNS settings using the Apple Utility on an iPad. HELP!!!

First, I am assuming that you are trying to administer your AirPort base station for a static IP address using the iOS version of the AirPort Utility ... correct?
If so, then to do so:
Start the AirPort Utility app on the iPad
Select your base station.
Select Edit
Select Internet Connection
Select Static
Enter the appropriate IP address information
Select Done
Sorry, it does not appear that direct input for DNS IP addresses is an available option with this version of the iOS AirPort Utility app. Not sure why this was not included.

Is an 'external' static IP address required to set up DNS

Hi there
I'm going to be setting up a OSX Server 10.3 machine as an open directory master, to take advantage of single sign-on capabilities.
From what I have read in manuals and in this topic: http://discussions.apple.com/thread.jspa?threadID=977178&tstart=15 , it is necessary to configure the DNS service first. However, the topic talks about having an external IP address for the server, as well as for the internet router.
Is this the only method that will work? The network only has one external IP address as far as I am aware.
Any thoughts greatly appreciated.

The answer is, it depends.
If you want your server to provide any external services then it will need an external IP address. Now, depending on your network, you may be able to use a single IP address on your router, having it NAT incoming connections via port forwarding - that's a common setup.
The bigger issue is whether you need a static IP address or can live with a dynamic one. A static IP address is required if you're running certain services such as DNS or Mail. Other services might be able to get by with a dynamic IP, depending on what you're doing with them (for example, it's OK to run a personal web site on a dynamic IP address, but you wouldn't want to do that for a corporate web site that gets a lot of traffic.

Oracle 11gR2 RAC VM and SCAN and DNS and /etc/hosts (two) setup questions

Hi,
I am looking forward to setting up two Oracle 11gR2 RAC instances
on my Oracle VM test machine.
I plan on using the Oracle 11gR2 RAC VM template.
I want the final Oracle 11gR2 RAC instances to have SCAN that uses DNS.
The DNS will be pre-installed in the JeOS.
My first simple question about the setup is the following.
In my DNS name file, for example,
/var/named/chroot/var/named/milkyway.univ.db
do I need to provide the racnode1 and racnode2 information,
for example,
# DNS name file (snippet)
myjeos IN A 192.168.1.150
racnode1 IN A 192.168.1.161
racnode1-vip IN A 192.168.1.163
racnode2 IN A 192.168.1.162
racnode2-vip IN A 192.168.1.164
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
Or, can I just provide only the rac-scan information
# DNS name file alternate (snippet)
myjeos IN A 192.168.1.150
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
What I am getting at is the following.
Within the install process, will racnode1, racnode1-vip, racnode2,
and racnode2-vip host names and their IP address be written
to the RAC instances /etc/hosts files? (So I should not bother
to put them in the DNS name file like '# DNS name file alternate (snippet)'?)
Or, should I put the racnode and racnode-vip host names and IP addresses
in the DNS name file like '# DNS name file (snippet)'?
The second question is the following.
Are the cluster name and the scan name allowed to be different?
Currently, I would plan them to be different,
for example, rac-cluster and rac-scan.
Or, are they required to be the same,
for example, rac-cluster and rac-cluster.
Thank you.

We write this data out to /etc/hosts just to reduce the amount of round-trip DNS requests the cluster nodes make for themselves.
