ifcfg-$DEV-range* not inheriting netmask from parent config
Last modified: 2014-03-16 22:43:53 EDT
Description of problem: ifcfg-eth0-range0 does not inherit network mask from parent config Version-Release number of selected component (if applicable): initscripts-7.31.9.EL-1 How reproducible: always Steps to Reproduce: 1.configure ifcfg-eth0 with desired netmask (in my case 255.255.255.224) 2.configure ifcfg-eth0-range0 with no netmask entry 3.restart network Actual results: Netmask from parent config ignored (resulting netmask 255.255.255.0) Expected results: Netmask from parent config inherited (in my case 255.255.255.224) Additional info: This seemed to work OK on the 7.x series. The documentation within ifup-aliases also specifically states that "Range files also inherit configuration from the ifcfg-$DEV file just like normal."
This is a result of the problem described in bug 65415. You can work around it by making sure that the range filenames match the egrep -v that's shown in that bug (and thus are excluded from the list of interfaces); for example, you can name them "-range:0" rather than just "-range0", since a colon is one of the exception strings listed in the egrep -v. Bill Nottingham closed bug 65415, and in response to a query I sent him regarding RHEL3, he replied: "It's fixed on the RHEL branch as well, should be in the next scheduled update (update 4)." Bill, feel free to add any more info...for example, it would be useful to know approximately when RHEL3 update 4 is expected to be released.
U4 came out some time ago :-)
Yes, this should be fixed in 7.31.18.EL-1.
