Please read the "Question Guidelines" link in my posting signature.

You have given us NO DETAILS at all, with which to help you. You don't tell us version/distro of Linux, what kind of hardware, what kind of network, what environment (home or office), etc. All you've said is you installed Linux....we need more than that.

Ok, a bit more information, but still NOTHING that really helps. What kind of laptop? Ethernet card? Wirless? How are you connecting (which one are you choosing?) And if this is at your home, alone....WHERE is the Oracle database you want to connect with?? What kind of home networking hardware are you using? Is there some reason you haven't set up your NIC(s) to use DHCP from the home router, versus static???

Chances are, you don't have a default route set, nor do you have DNS servers set. Can you post the output of "ifconfig -a"?

AGAIN you need to read the "Question Guidelines" link, as well as the LQ Rules. Open a new thread for a new question, and you are STILL not providing enough details to let anyone help you. What "email" are you trying to configure? How? Email client or server? What desktop GUI are you using?

hi sir,

it is ethernet based laptop and ASUS X54c it is in home no router just simple laptop and i configured oracle database 11g R2. listener is okay. but when i am trying to use emctl it says no network

veerain · 12-22-2014, 12:08 AM

Run command
ip a

and check it's output it shows all interfaces with IP address. Usually for standalone system you should use 127.0.0.1 instead.

anilreddy.nhinfomedia · 12-22-2014, 12:43 AM

then how should i connect my database with ip address

what happen when i use other ip address if like 192.168.10.15 and i want to connect listener.ora with ip address of 192.168.10.15

because i mentioned 192.168.10.15

As requested by TBOne, what networking hardware are you using? If no router, is your laptop connected to the internet via an ADSL or Cable modem? You state ethernet rather than WiFi.
I'd think your gateway address would be more like 192.168.0.1 or 192.168.1.1 which are fairly standard? If wired, you appear to have set an IP with a different domain which would prevent communication.

To clarify, is your Oracle database on another PC/Server?, if so what's it's IP, whats your laptop's IP and how are they networked together?

Forgive me, but your post implies that your laptop has no network connection which would be one reason you get "connection timed out", are unable to ping and can't set up email.

Maybe I've missed something?

Play Bonny!

As other members have stated you have not provided enough information for us to aid you in diagnosis of the problem(s) or issues.

I like to provide the following for new users. RUTE is a good tutorial. Plus look at #10 below for some helpful network information;

FYI: Netiquette is a set of social conventions that facilitate interaction over networks, ranging from Usenet and mailing lists to blogs and forums.

FYI: I suggest that you look at 'How to Ask Questions the Smart Way' so in the future your queries provide information that will aid us in diagnosis of the problem or query.

Please notice that I am using root, identified by '~#' prompt in the code windows.

Identify the Ethernet device;

Code:

~# lspci -kvv |grep -i eth
0a:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168 PCI Express Gigabit Ethernet controller (rev 06)

Please notice that I am using a Realtek RTL8111/8168, I would then check for the installed module & firmware by using;

Code:

~#lspci -vv

Which would show device information & the kernel driver in use;

Code:

 Kernel driver in use: r8169
        Kernel modules: r8169

I would then do;

Code:

~#lsmod

then do a

Code:

~#modinfo r8169

to be sure that would be the correct driver., which it is for my device.
Then you could use;

Code:

~#ifconfig -a      #<- this will show us the devices recognized even the ones that are down
~#route -n                     #<- this will show the kernel route table
~#cat /etc/resolv.conf     #<- this will show us the nameservers in use

By providing the above we could see if the devices are setup properly or see where you may need to modify.
Hope this helps.
Have fun & enjoy!
