Hello everyone,

I have connected two laptops with a lan cable, and I'm trying to ping each other after giving them static IP's.
The error I am getting is Destination Host Unreachable. Please help ASAP.

Thank You.

Have you set a default route on each system, pointing at the other? The command 'netstat -r' will show the routing table. You should have an entry like this:

The gateway on your systems should show the ip address of the other system.

@OP
If you want to connect both laptops directly to each other, you'll need a crossover cable.
No need to specify gateways or routes. Just assign them static IPs as you already have.

Regards

this is the very old rhel5.4
the current is 5.10

5.4 is 6 versions out of date

with rhel6.5 as the current

the older LEGACY rhel5 is good for OLD legacy hardware

so are these two laptops OLD 2000 to 2005 laptops

Only when using 15+ year old systems.
https://en.wikipedia.org/wiki/Ethern...atic_crossover

current eth ports can use a port to port

if you do have old hardware requiring the use of rhel5 ( you might want to upgrade to the current legacy rhel5.10)

maybe a crossover might be needed
but most likely not

The output of netstat -r is
----------------------------------------------------------------------------------------------
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
default 192.168.1.105 0.0.0.0 UG 0 0 0 eth0
-----------------------------------------------------------------------------------------------
192.168.1.105 is the ip of other laptop. I am encountering a new problem on the laptop with ip 105. On bringing up the eth0 of that system, error displayed is "device eth0 has different MAC address than expected, ignoring".

Also the ifconfig eth0 up shows :
-------------------------------------------------------------------
eth0: unknown interface: no such device
-------------------------------------------------------------------

And the output of netstat -r is empty kernel routing table.
Also the output of ifconfig -a has no entry for eth0.

I am downloading RHEL 6.5. I have x86_64 architecture, i5.

Because these are older machines, it is possible you may need a cross over cable. I can not be sure, just keep that in mind.

The one machines routing table looks OK. Your machine 192.168.1.105 appears to be the problem.

If you run 'ifconfig' without specifying any adapter, does it show any active interfaces? Possibly eth0 is now eth1??? Just a thought.

It shows only lo, and no other device. And, the machines are not older I guess. Both are x86_64 architectures.

well you ARE using RHEL 6.5 now
so you did create an account with redhat
this would be the 30 day TRIAL!!! version???
or
did you already buy the REQUIRED support contract
https://www.redhat.com/apps/store/desktop/

if you did not buy the required license and are not going to
-- then do not use RHEL--

install CentOS 6.5
it is a free rebuild of RHEL 6.5

I have downloaded it from torrent. And, on installation it is showing same problems as I have mentioned earlier. On typing :

ifconfig eth0 up

It says that

eth0: unknown interface: No such device

You shouldn't be confessing that haha

You have better choices: Oracle Linux and CentOS

if you are NOT going to pay for Redhat
Then DO NOT USE IT!!!!
you will NOT be able to install software unless you BUY the REQUIRED support contract !!!


go to redhat
REGISTER WITH REDHAT
grab a official copy of RHEL 6
install and REGISTER the install ( desktop inon you click on)
BUY the required support contract!!!!!!!!!!
--- a MUST DO !!!!!!!!!!

--- single desktop install ---
https://www.redhat.com/apps/store/desktop/


or

install the FREE!!!!!!!!! rebuild called
" CentOS 6.5 "
