Samba Authentication - gethostbyaddr

jerry1 — Mon, 23 May 2005 11:48:56 GMT

I had a similar problem with rexecd but
there is a switch(if the patch is applied)
for rexecd, "-s", which tells rexecd to not
deny the connection if the client IP does
not match the DNS entry.

Is there a similar switch for Samba to not
do a DNS lookup of a connecting client when
the IP address of the connecting client does
not match the DNS entry of that client. It's
a DHCP VPN problem we have sometimes with
people taking their laptops home and getting
an IP from the VPN connection and registering
it in our DHCP server as another network IP
for that client.

Check the smb.conf file. ( man smb.conf ) .. you should be able to turn this off with this parameter:

hostname lookups (G)
Specifies whether samba should use (expensive) hostname lookups or use the ip addresses instead. An example place where hostname lookups are currently used is when checking the hosts deny and hosts allow.

Default: hostname lookups = yes

Example: hostname lookups = no
