Hosts file ignored, no DNS entry but still routes!!
Hi all,
I have an entry in my hosts file on a server called tractor as follows:
Code:
10.67.34.128 digger-m2m digger
I have a DNS server configured but it doesn't seem to know about digger. When I do an nslookup on tractor for digger i get the following:
Code:
new_dns1.oam.uk can't find digger: Non existant host/domain
There are 2 interfaces on digger - 1 is an OAM interface and the other is a machine to machine interface. The 10.67.34.128 address is the machine to machine interface and the OAM interface has address 172.34.85.102.
If I ping digger from tractor I can see by running a snoop on digger that I am pinging the 172 address but clearly my hosts file has digger listed at the 10 address.
I'm begining to wonder if tractor has somehow cached an association between digger and the 172 address. If so does anybody know how to clear it, or know why I'm getting the above behaviour with my hosts file seemingly being ignored?
Thanks!!!!

I've just discovered that if I change my host entry on tractor to have digger_new at the end of it rather than just digger and then I ping digger_new it pings the right address.
Hello guys,
I am new to AIX .
I have two AIX v5.3 servers running BIND DNS service on them. The plan is to shut down only the DNS service on them, but in order to do that I have to determine which internal hosts are still using the servers to resolve DNS queries.
Can you please advice on... (2 Replies)
Hello,
For what purpose /etc/hosts file is used.I mean how any request coming to a DNS server or a switch would know that which name and ip are configured in /etc/hosts files of a server?

Hello all,
I´m on Red Hat Enterprise Server 4.5
I´m wondering if it is possible to disable the need to add every IP machine entry in the file /etc/hosts to allow it to connect to Red hat?
I´m getting "where are you?" message. This is solved adding the machine ip where I´m working.

As i understand, host/nslookup/dig only query DNS server to resolve name to ip.
ping can query both, but it seems if ping is blocked, ping won't return IP.
traceroute can query both, but i am not able to test if traceroute is blocked, What is the result?
Neither ping/traceroute is... (3 Replies)

Hi all
Is there any reason to have "hosts ldap dns" as line in /etc/nsswitch.conf ? My understanding is that ldap does not contain any host information..(?)

Hi,
This is more of a verification rather than a question of technical nature.
This is based on solaris 10 machine
Could we use Virtual hosts (within our hosts file):
123.1.1.10 virtual_host_name
123.1.1.10 host_A
(note: 123.1.1.10 - host_A is also in our DNS server entry)
And... (0 Replies)
