May you help saying me how to flush a specific domain in Linux SunOS5
I know the command rndc is to flush DNS cache, but I would like to know:
1- How to do a flush only on specific domain
2- How to see the content of DNS Resolver cache (similar to info given by IPCONFIG /displaydns in Windows)
If I send below command with flushname, I get an error:
Thanks in advance for any help on this.

Hi,
I am new in exim. I am trying to configure a debian server running exim4 such that it relays only mails to our domain (@abcd.de).The exim server uses a smarthost for relaying. I do not get it to block outgoing mails to domains different from ours (i.e. with the "standard" configuration it... (0 Replies)
Hello,
I'm using CentOS 5.3, and I connect to a VPN in order to work. The problem is that I'm constantly accessing things on the local network and the remote network. But once I'm connected to the VPN I can't access local addresses by name, I have to use the ip-address.
What I'd like is to... (4 Replies)
Hi all!
I try to find all directories which match a specific path, e.g., to find all directories matching "data/temp/" assuming a directory structure like this:

The "find" command under SunOS 5.9 DOES... (7 Replies)

rndc-confgen
RNDC-CONFGEN(8)RNDC-CONFGEN(8)NAME
rndc-confgen - rndc key generation tool
SYNOPSIS
rndc-confgen [ -a ] [ -b keysize ] [ -c keyfile ] [ -h ] [ -k keyname ] [ -p port ] [ -r randomfile ] [ -s address ] [ -t chrootdir
] [ -u user ]
DESCRIPTION
rndc-confgen generates configuration files for rndc. It can be used as a convenient alternative to writing the rndc.conf file and the cor-
responding controls and key statements in named.conf by hand. Alternatively, it can be run with the -a option to set up a rndc.key file
and avoid the need for a rndc.conf file and a controls statement altogether.
OPTIONS -a Do automatic rndc configuration. This creates a file rndc.key in /etc (or whatever sysconfdir was specified as when BIND was built)
that is read by both rndc and named on startup. The rndc.key file defines a default command channel and authentication key allowing
rndc to communicate with named with no further configuration.
Running rndc-confgen -a allows BIND 9 and rndc to be used as drop-in replacements for BIND 8 and ndc, with no changes to the exist-
ing BIND 8 named.conf file.
-b keysize
Specifies the size of the authentication key in bits. Must be between 1 and 512 bits; the default is 128.
-c keyfile
Used with the -a option to specify an alternate location for rndc.key.
-h Prints a short summary of the options and arguments to rndc-confgen.
-k keyname
Specifies the key name of the rndc authentication key. This must be a valid domain name. The default is rndc-key.
-p port
Specifies the command channel port where named listens for connections from rndc. The default is 953.
-r randomfile
Specifies a source of random data for generating the authoriazation. If the operating system does not provide a /dev/random or
equivalent device, the default source of randomness is keyboard input. randomdev specifies the name of a character device or file
containing random data to be used instead of the default. The special value keyboard indicates that keyboard input should be used.
-s address
Specifies the IP address where named listens for command channel connections from rndc. The default is the loopback address
127.0.0.1.
-t chrootdir
Used with the -a option to specify a directory where named will run chrooted. An additional copy of the rndc.key will be written
relative to this directory so that it will be found by the chrooted named.
-u user
Used with the -a option to set the owner of the rndc.key file generated. If -t is also specified only the file in the chroot area
has its owner changed.
EXAMPLES
To allow rndc to be used with no manual configuration, run
rndc-confgen -a
To print a sample rndc.conf file and corresponding controls and key statements to be manually inserted into named.conf, run
rndc-confgen
