Package: winbind Version: 3.0.24-6etch9 Severity: wishlist I have some Windows hosts connected to a Debian host via a routed OpenVPN interface. The names of these hosts can be resolved through WINS (Samba running on the Debian host), but not through the Debian name resolution sequence unless I install winbind and include "wins" in the "hosts:" line of /etc/nsswitch.conf. Doing that works fine, but there is a significant penalty: a Debian lookup for a nonexistent name now takes several orders of magnitude longer, e.g., 1.8 seconds instead of .004 seconds. The reason for the delay is that if a name reaches the "wins" method and is a miss in the WINS server, the "wins" method always attempts to resolve the name with a broadcast, and this takes a relatively long time to fail.
It is therefore my wishlist request to be able to configure Debian to resolve names with a WINS lookup but avoid superfluous broadcasting for names. "Superfluous" in my case (and it must be common) means broadcasts for all but single-label unqualified names (more specifically, valid Netbios names, e.g., <15 chars). This could be done any of several ways, but it would be ideal to be able to configure the "wins" method to return failure immediately on lookups of anything but a valid Netbios name. This requires examining and parsing the name query, however. It would work nearly as well to be able to write an /etc/nsswitch.conf that specifies only WINS lookups and never broadcasts, since I don't expect ever to find a host via broadcast that isn't already in the WINS database. This remedy ought to be relatively easy to implement: since the WINS lookup and the broadcast are separate phases anyway, skipping one should be easy. One could implement new methods "winsonly" and "winsbroadcast" while retaining legacy "wins" meaning "winsonly winsbroadcast". Alternatively, if the WINS server is already aware of the Samba config value of "name resolve order" then this value could determine the behavior of the "wins" method in /etc/nsswitch.conf. -- System Information: Debian Release: 4.0 APT prefers stable APT policy: (990, 'stable') Architecture: amd64 (x86_64) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.18-13etch3-corax-1 Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Versions of packages winbind depends on: ii add 3.102 Add and remove users and groups ii lib 2.6.1-1 GNU C Library: Shared libraries ii lib 1.39+1.40-WIP-2006.11.14+dfsg-2etch1 common error description library ii lib 1.4.4-7etch4 MIT Kerberos runtime libraries ii lib 2.1.30-13.3 OpenLDAP libraries ii lib 0.79-5 Pluggable Authentication Modules l ii lib 1.10-3 lib for parsing cmdline parameters ii lsb 3.1-23.2etch1 Linux Standard Base 3.1 init scrip ii sam 3.0.24-6etch9 Samba common files used by both th winbind recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
