Comment 12 Erinn Looney-Triggs 2011-12-06 13:09:59 EST
Unless I am missing something here, even after updating to RHEL 6.2 I cannot see this in the man page, I can see another overlay the EDNS0 options but not the single-request-open option. man-pages-3.22-17.el6.noarch man-pages-overrides-6.2.3-2.el6.noarch -Erinn
Comment 13 Mihai Harpau 2011-12-06 15:02:31 EST
I see this sub-paragraph in "man 5 resolv.conf" under options: single-request-reopen (since glibc 2.9) The resolver uses the same socket for the A and AAAA requests. Some hardware mistakenly only sends back one reply. When that happens the client sytem will sit and wait for the second reply. Turning this option on changes this behavior so that if two requests from the same port are not handled correctly it will close the socket and open a new one before sending the second request. man-pages-3.22-17.el6.noarch man-pages-overrides-6.2.3-2.el6.noarch
Comment 14 Erinn Looney-Triggs 2011-12-06 15:27:12 EST
Hmm pretty clearly I am doing somehting wrong. Looked on multiple 6.2 systems after the update and was unable to see that paragraph. Glad though that other people can.

manpath was bad, this works just fine, sorry for all the noise.
Comment 16 todd_lewis 2012-09-11 15:24:15 EDT
I see that option documented on a Red Hat Enterprise Linux Server release 6.3 (Santiago) system, which claims at the bottom of the man page: "This page is part of release 3.22 of the Linux man-pages project." However, it isn't in the Fedora-17 resolv.conf man page, which claims: "This page is part of release 3.35 of the Linux man-pages project." Nor is it in the git HEAD at the man-pages project. I'm not sure what the process is for moving fixes across projects, but something has slipped throught the cracks here that could be better. Just sayin'.
Comment 17 Peter Schiffer 2012-09-12 05:46:12 EDT
Thanks for the notice Todd. I'll fix this in Fedora. (And thanks for submitting this to upstream). I am going to review man-pages bugs in RHEL and fix them in Fedora, it looks like there are more bugs like this one.. peter
