2 - In event of no response from server 1, this request is sent to the server 2.
3 - In event of no response from server 2, go back to step 1 (4 times max.).
4 - In event of negative answer from any server, the resolution is aborted.
5 - If other requests can be sent (using default DNS domains are defined), go back to step 1.
Example: looking at the screen shots of the Chapter 3.1, these are the DNS requests sent to
resolve "as400" with 2 DNS servers and 2 default DNS domains (of course this process is stopped
if one DNS server sends back a positive response):
- "as400.servers.axel.com" to DNS server 1
- "as400.servers.axel.com" to DNS server 2
- "as400.terminals.axel.com" to DNS server 1
- "as400.terminals.axel.com" to DNS server 2
- "as400" to DNS server 1
- "as400" to DNS server 2
c) Messages Displayed on the AX3000 Screen
To open a session the AX3000 must resolve the host name (if no IP address has been associated
through the set-up).
This is a screen-shot example when the resolution successes:
Connecting to as400.servers.axel.com:23 (Telnet)...
Session number 1
Resolving...
Resolved: 192.168.1.180
Connected
Explanation : the AX3000 attempts to resolve "as400.servers.axel.com". The resolution process
returns the IP address which is 192.168.1.180.
In the event of a problem, the "Resolved: a.b.c.d" message is replaced by an error message. For
example:
Connecting to as400.servers.axel.com:23 (Telnet)...
Session number 1
Resolving...
Srv: domain not found
Press <Ctrl><Alt><Shift><D> to close this session
Error messages : error messages reported by the DNS server begins with Srv. Error messages
from the thin client begin with "Loc". The main messages are:
- Srv: domain not found : the name doesn't exist within this domain.
- Srv: refused query : the DNS servers refuses to respond to the request. This could be due
to a DNS server security function.
- Loc: no DNS server defined : no DNS server has been defined through the AX3000 Set-Up.
- Loc: name syntax error : the syntax of the name to resolve is not correct (for example two
consecutive dots: as400.servers).
- Loc: timeout : no DNS server responds
- Loc: no memory : due to a temporary memory overload, the AX3000 can not process the
name resolution. Retry later.
When the resolution fails, the session must be manually closed. This is done by pressing
<Ctrl><Alt><Shift><D>.
