Dear Skunks I have a setup where my core servers will have a secondary IP , now my windows servers are responding correctly with a secondary ip but i have 3 linux boxes which have refused to work with the secondary IP , any pointers on how to go about this? -- GG
Gitagia, If the secondary IP is in the same class as the primary one, then your subnet mask for the secondary IP must be a /32 (255.255.255.255) for the box to respond to it. If it's a different class, then I think your firewall is blocking the packets to this secondary IP. On 31 August 2016 at 17:54, geoffrey gitagia via skunkworks < skunkworks@lists.my.co.ke> wrote:

Tail /var/log/messages and see what the cause might be. On Wed, Aug 31, 2016 at 5:54 PM, geoffrey gitagia via skunkworks < skunkworks@lists.my.co.ke> wrote:

Geoffrey, Start with some background info on how you configured your secondary IP. What method did you use to add the secondary IP? Was it via the legacy ethx:x alias method? Share what you did and failed, then you can get advise on where you went wrong. On 31 August 2016 at 18:54, geoffrey gitagia via skunkworks < skunkworks@lists.my.co.ke> wrote:

Hehee.. These are some of the things that make Linux complicated:-) In *BSD land we edit /etc/rc.conf and add the IPs viz: ifconfig_rl0="inet 192.168.55.254 netmask 255.255.255.0" ifconfig_rl0_alias0="inet 192.168.55.253 netmask 255.255.255.255" ifconfig_rl0_alias1="inet 192.168.55.252 netmask 255.255.255.255" then restart the networking daemon or use CLI to do the same: ifconfig rl0 inet a.b.c.d netmask n.n.n.n alias up... The _aliasX denotes a secondary IP and the subnet mask must be a /32 because it's in the same class. Wait until you come to /etc/networking/* blah in Linux and it gets too confusing. Then there are different tools to configure networks.. On 31 August 2016 at 21:40, TJ via skunkworks <skunkworks@lists.my.co.ke> wrote:
