With iptables version 1.4.21 and RHEL7.2 and ipset v6.19, I have been observing a difference in ipsets. It seems that the ipsets are displayed as follows:- root@system> ipset list Name: BlockList Type: hash:ip Revision: 1 Header: family inet hashsize 4096 maxelem 2147483648 Size in memory: 65680 References: 0 Members:Name: BlockList2 Type: hash:ip Revision: 3 Header: family inet hashsize 4096 maxelem 2147483648 Size in memory: 65680References: 0 Members:What is the significance of this revision? Could anyone let me know.On RHEL6.6 and an older version of iptables 1.4.7 and ipset v6.11, I could get this as the output:- Name: myset Type: hash:net Header: family inet hashsize 1024 maxelem 65536 Size in memory: 16848 References: 0 Members: 27.8.0.0/13 58.16.0.0/15 14.144.0.0/12Here I can see that there is no such thing called Revision.Any help or guidance will be appreciated.
