One of the two DNS server going down causes impacts
Our computing enviornment consists for Linux, Solaris , AIX, Windows. /etc/resolv.conf file of each *nix has two entries. When the 2nd one goes down we are seeing impacts on AIX hosted services. We are breaking our head, to no avail yet. We have not seen any impact on non-AIX hosted services. While 2nd DNS server remains down, nslookup returns hostnames immediately.
We are trying to avoid running tcpdump, and was trying to capture DNS traffic from client through netstat. But netstat does not capture DNS traffic either.
Would you please give us a hand?

I'm running on UNIX with Solaris. I need to change the Timezone on the box and was going to make the changes to the files and then reboot the box.
Someone warned me that this method should not be used and that a util (unconfig.sys I think it was) should be used to make the changes.
Any ideas... (2 Replies)

recserv(1M) recserv(1M)
NAME
recserv - HP SharedX Receiver Service
SYNOPSIS
/usr/lbin/recserv
DESCRIPTION
HP SharedX Receiver Service provides a method for a receiver to allow the sharing of windows without explicitly performing any xhost com-
mands. The Internet daemon (inetd(1M)) executes recserv when it receives a service request at the port listed in the services data base
for recserv (see inetd(1m) and services(4)).
When recserv is executed via inetd, a dialog box appears informing the receiver of the share request by the sender. The receiver can allow
or disallow the share request by selecting the YES or NO button.
recserv allows sharing by xhosting the sender just long enough for it to make a connection to the receiver. Once the connection is estab-
lished recserv removes the sender from the access control list, unless the sender was entered in the list prior to the execution of rec-
serv. Since no permanent change is made to the access control list, security is maintained at its highest level.
To start recserv from the Internet daemon, the configuration file /etc/inetd.conf must include the single line entry,
recserv stream tcp nowait bin /usr/lbin/recserv recserv -display :0
If the sharing is going to be done between IPv6 machines, the protocol field of the above entry in /etc/inetd.conf file of the receiver
machine should be changed to tcp6 as follows
recserv stream tcp6 nowait bin /usr/lbin/recserv recserv -display :0
and the services file /etc/services must include the line,
recserv 7815/tcp # SharedX Receiver Service
Receiver Service options, set by selecting the Options button, dictate the behavior of recserv. The behavior can also be set by running
recserv manually. In either case, an X server resource is set dictating the behavior for subsequent invocations of recserv.
OPTIONS
The following options allow different behavior according to user preferences.
AlwaysAsk
The dialog will pop up each time sharing is requested, regardless of the security on your X server.
AlwaysAllow
The dialog box never appears, but sharing will always be allowed.
AskUnhosted
The dialog will pop up only if the sender's machine is not hosted on your machine. If the sender's machine is already
hosted, sharing will occur without a dialog appearing.
NeverAsk
The dialog will never appear. Windows are shared only if the sender's machine is already hosted by your server.
To set resources (system behavior, label strings, etc) globally for a system, edit the file /usr/lib/X11/app-defaults/RecServ.
