Re: Problem with sudo in 6.5 (final)

I deal with many CentoOS servers that have been updated to 6.5 and we rely heavily on sudo for developers to access application UIDs and we have not see any issues.

Re: BIND Routing Tables

All BIND does is resolve a name to an IP address or IP address to a name. There is no routeing involved.

If you are hosting multiple domains in BIND you need to have individual zone files for each domain you are going to resolve for.

Re: Question about LDAP and DNS

The "dc=example,dc=com" is normally used to define the LDAP search base not the host to bind to and doesn't require DNS entry.

Is there a host entry on the phone configuration for LDAP user lookup? Or does it look for a _ldap._tcp SRV entry in DNS?

When a browser connects to an SSL site the the server will send the host certificate as well as the whole CA chain and if the r...

Re: Firewall box setup in front of sonicwall

As someone who is new to linux it is probably not a good thing to try and setup your own firewall. Hardened appliances like the SonicWall are inherently more secure that a general purpose computer. If you still want to move away from the SonicWall I would suggest using something like pfSense instead...

Re: why my dhcp server assign ip address on eth0 and eth1 bo

You need to bind the dhcpd service to the eth1 interface only. You do this in /etc/sysconfig/dhcpd by adding the name of the interface to the list of DHCPDARGS:
DHCPDARGS=eth1
