Can't ping the host name or host IP address from host.

Can't ping the host name or host IP address from host.

Post by Owen E Dennen » Tue, 03 Aug 1999 04:00:00



Hello there,
I have the unusual problem of not being able to ping the machines host name
or host IP address from the host.
I've checkout the network settings and I can't seem to find any problems.  I
am able to ping & telnet to the machine
from the network.  Seems quite strange.

Any help would be really appreciated.

thanks,

Owen.

Here is output from ifconfig

1. can't ping host or host IP from host ?

Hello there,

I am unable to ping the host machine name or by IP address from the host
itself.
All the network config seems to check out correctly.  I can ping & telnet
the machine from the network.

Any help or pointers would be greatly appreciated.

thanks,
Owen.

2. Yamaha CDR102 drive - scsi problems

3. /etc/hosts (or NIS host map): official-host-name vs nicknames

4. IBM screws RT owners?

5. Get 'cannot connect to host', yet can ping remote host!!

6. Reentrancy

7. ping -g 'gateway-IP' 'host-IP' DOESN'T work!

8. leave accept

9. IP Masquerading - Can't use Host names only IP address

10. Get Host Address from Host Name

11. Strange network problems - pings to host are fine, pings from host fail

12. ICMP HOST cannot build IP Header address to echo ICMP HOST

13. Host IP number instead of host name ?
