Package: libc6 Version: 2.2.5-11.5 Severity: normal When using libldap in a LDAP client program, which connects to a LDAP server on localhost on port 389 (default LDAP port), libldap uses getaddrinfo() to resolve localhost into 127.0.0.1.
The resolution process involves querying the DNS although the nsswitch.conf entry states : hosts: files dns This can be very confusing, for instance if the DNS entries in /etc/resolv.conf get configured in a wrong way. In this case, requests to the DNS will fail after a 5 seconds lag, and LDAP connections will work, but involving very strange lags of 5 secs... I ran into this problem recently and described it here : http://www.openldap.org/lists/openldap-bugs/200309/msg00058.html I consider that this problem can greatly diminish some services based on LDAP useability, if unnecessary lags can pop from time to time... This problem of getaddrinfo's behaviour was addressed also in bug #160596, but the behaviour described there was not concerning localhost. I'd assume the resolution of localhost should somehow be handled differently than the one of other machine names... so this may not be considered the same problem exactly. This may have been corrected in the "testing" version of the glibc, but had no time to check into the source for differences between the two versions. But straces of the same LDAP client on a stable or testing machine configured the same in nsswitch.conf and resolv.conf show that DNS resolution seems to be no longer attempted. -- System Information Debian Release: 3.0 Architecture: i386 Kernel: Linux picolibre.int-evry.fr 2.4.21 #1 Mon Sep 15 15:04:20 CEST 2003 i686 Locale: LANG=C, LC_CTYPE=C -- Olivier BERGER <[EMAIL PROTECTED]> Ing�nieur Recherche - Dept INF INT Evry (http://www.int-evry.fr) OpenPGP-Id: 1024D/6B829EEC -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
