Hi All

We had DNS servers running on rhel 2.1 As , One Primary and One Secondary running DHCP,WebServer etc .

Recently we migrated our DNS servers from rhel 2.1 as to rhel 4 as 64 bit .
We see lot of performance issues with new DNS servers . We manage our dns servers using webmin .
We have rysnc running on new Primary DNS Servers every 1 hr for keepings our webservers updated .

OLd DNS servers runs on dl 360 g3 RHEL 2.1 As
New DNS servers runs on DL 380 G5 RHEL 4 U 5 AS

Need ur Valuable advice on getting this issues fixed

>>> We see lot of performance issues with new DNS servers . We manage our dns servers using webmin .

Â¿Can you explain better the "perfomance issue"?

>>> We have rysnc running on new Primary DNS Servers every 1 hr for keepings our webservers updated .

Â¿Do you think that this is related to the problem? Â¿What is the real problem? Slow DNS queries/answers, slow web access?

Hello

You can see list of Source RPMS at
ftp://ftp.redhat.com/pub/redhat/linux/enterprise/5Server/en/os/SRPMS/
Version numbers are encoded in RPM file names.

Apache package is named 'httpd', latest is
httpd-2.2.3-11.el5_1.3.src.rpm. So version is 2.2.3 release 11.

Latest MySQL is mysql-5.0.45-7.el5.src.rpm, version is 5.0.45 release 7
