Network ip issue
 

Hi All;

In my laptop i instlled vmware version 9.
On virtual machine i installed linux distro.
I enabled ip configuraion using DHCP.It was working fine. recently i tried to set static ip.
After that i facing n/w issue.

...and since you don't tell us what 'linux distro' you installed, what the actual issue/problem is, give us error message(s), or tell us what you're trying to do, what do you think we'll be able to tell you??? Are you using IPv4 or 6? HOW did you set the static address? If you switch it back to DHCP, does it work??

Since you provide no useful details, the best anyone can guess at is "you set it up wrong". Either you didn't provide a default gateway, DNS server(s), a valid address, or some other piece of the network puzzle is missing. Figure out what that piece is, and correct it.

LINUX 5.5 distro installed.

using neat command i set static ip as '192.168.1.120'

again i have enabled dhcp. so now i am facing problem. I dont understand.

WHICH Linux 5.5??? RHEL? OEL? CentOS? ANY hints at all????
...and back to "you don't provide any useful details". You set the static IP...great. Did you read and UNDERSTAND the previous post? Did you set the default gateway? DNS? WHAT MESSAGES did you get? You say you enabled DHCP and you are 'facing problem'...which doesn't tell us if DHCP has STOPPED working, or if you just have the problem with static addresses.

AGAIN: provide details and ask a clear question if you need help. If you're using Oracle Linux 5, then we can suggest you contact Oracle, since that is a COMMERCIAL PRODUCT. You have been advised of this numerous times in the past, and have been asked for details several times previously too, but seem to ignore these requests. And did you try to look this up on Oracle's website (which, as a DBA, you should have access to, especially since you're PAYING FOR these products, right???)

Looks like Oracle EL 5 from the thumbnail.

If you tried to configure a static IP and it didn't work,.. you will need to post the output of these commands for anyone to help:

Hi TBone ;

I have installed OEL 5.5
I did NOT enable ipv4 or ipv6 .

What the actual issue/problem is, give us error message(s), or
tell us what you're trying to do, what do you think we'll be able to tell you???

When installing linux , i have selected 'network adapter as 'HOST ONLY'
then i choosed 'automatic ip address using 'dhcp'
so i got ip by default as '192.168.133.169'
Later using neat command i set static ip as '192.168.1.120'
then i have selected network adapter as 'bridged network'


Now i have removed everything!
again i set network adapter as 'host only'
but cannot enable any ip. this is problem.

HOW did you set the static address?
using 'neat' comamnd

If you switch it back to DHCP, does it work?
I tried , but not working. please see attached screen shot.

Did you set the default gateway? DNS? WHAT MESSAGES did you get?
I enabled when installing 'linux' .. i cannot recall anything.

Thanks TBone .. I hope ..

Please see attached screen shots.

If you don't enable ANY sort of IP, why do you think that it'll work???
What makes you think that the 120 address is correct? Are you sure nothing else is using it? Did you ask your networking folks what range your static address can go in??
Because you didn't set the address correctly, and have modified files outside of the neat utility. Restore the files back to their original state, THEN run the neat utility (after getting the correct network parameters from your networking team. Without default gateways, DNS servers, and a VALID IP address, things won't work. Ever.
No, you *TRIED* to set it using the neat command...but didn't actually show us what you filled in, only a screen shot of the error. And you've been asked if you have filled in the other networking parameters, but STILL haven't said if you did or not, and have not even acknowledged that you read that message.
...because you manually modified things. Restore the files you modified from backups.
AGAIN..you just say 'linux', when you should say OEL5. And, AGAIN: YOU NEED TO PAY FOR OEL5, and CONTACT ORACLE FOR HELP. You repeatedly ignore this.

You were sent a link from Oracle's knowledgebase. It has steps to take to get a static address/device configured. You either haven't read it, or haven't understood it. You don't provide what is needed for a static address to work, and until you do, IT WON'T.

CONTACT ORACLE SUPPORT...you say you're a DBA, and use both OEL and Oracle at your company, which means you are PAYING FOR SUPPORT. USE IT.

Hi TBone ;

I have installed in my laptop for personal use.
Not commercial purpose. So i cannot ask oracle supporting for personal use.

...which DOES NOT MATTER AT ALL, since no matter WHY you installed it, that is a COMMERCIAL PRODUCT, just like Red Hat Enterprise is. Not paying = DON'T USE IT, period. And you have said in other threads, repeatedly, that you use Oracle, RHEL, and OEL at your workplace, so logging a support call should be very easy to do.

That said, did you read and understand the links provided to you previously, and the instructions you were handed?? Did you look on the Oracle knowledgebase, for instructions on how to do this? Have you done/tried ANYTHING suggested of you yet?
