Re: Discussing ideas or wish list
Thanks for reply. I am an user. I am using or thinking from the user perspective. 1) Perl version change within Major release Do you see the problem with having to support an ancient Perl version that is 13 years old? I'd suspect many modern Perl applications to not even work on Perl 5.8.9. CentOS shipped Perl 5.8 in CentOS 5 series. They shipped Perl 5.10 in CentOS 6 series. So far I have no problem in doing the OS upgrade within the minor release. It is because the Perl (or other packages eg. gcc/python) version is consistent between the OS major versions. Let share an experience for my case. I have installed OTRS (a great ticketing system) in FreeBSD 9.0. The Perl version at that time is 5.12. For me, upgrading to FreeBSD 9.1 take some time because the Perl version at that time is 5.14. OTRS depends on lots of Perl/p5 modules/packages. This is not scalable if I need to upgrade multiple servers. Some (crazy?) ideas: a) Is it possible to install multiple Perl versions in the same server? Each third party Perl packages would linked to the corresponding Perl versions? Users have to update /usr/bin/perl to link to the desired Perl version (or using wrapper mechanism like /etc/mail/mail.conf). The installed package may like these: perl58-5.8.xxx p5-perl58-Net-zzz perl510-5.10.yyy p5-perl510-Net-zzz In this case, the user can install multiple Perl in the FreeBSD system. b) Try to use the newest stable Perl version at the very beginning FreeBSD major release. And try to maintain the Perl major version consistent within the FreeBSD minor release. For example, using Perl 5.14 at FreeBSD 9.0 and Perl 5.18 for FreeBSD 10.0. 2) pkgng man pkg-check pkg check -s is used to find invalid checksums for installed packages. I think this does not protect from the checksum and the files is being changed at the same time. When using pkg_add -r, I am concerned that if the packages was being tampered. And I have no way to verify it. Or how can user authenticate that the package is build by FreeBSD? I don't think packages are signed yet, but this is permitted by the new pkg design and will hopefully happen before too long. Good to hear that. 3) systat I hope systat can record statistics periodically. Currently systat is like 'top', that is monitoring system resources in real time.

The change of Perl version may make user difficult to upgrade other perl packages due to dependency issues. The ports tree is a rolling release and decides what the default perl version is, not the FreeBSD release. Let's ignore that though and take a peek into history using FreeBSD 8 series as an example because it's closer to EoL. Perl 5.8.0 is officially released July 18, 2002. Perl 5.8.9 is officially EoL on Nov 6, 2008. FreeBSD 8.0 released Nov 25, 2009. The ports tree's default Perl version at that point in time is Perl 5.8.9. Both Perl 5.8.9 and 5.10.1 are available as packages at that time. FreeBSD 8.4 released June 7, 2013. The ports tree's default Perl version at that point in time is 5.14.2. FreeBSD 8.4 could be the last release in the FreeBSD 8.x series. Its estimated EoL is June 30, 2015. Do you see the problem with having to support an ancient Perl version that is 13 years old? I'd suspect many modern Perl applications to not even work on Perl 5.8.9. I know pkgng should replaced the old package management tools in FreeBSD 10, I hope the situation would improve. After the EoL of FreeBSD 8 (estimated June 30, 2015) the old package tools are scheduled to be removed from FreeBSD. This change will be MFC'd back to 9-STABLE and the release at that time (perhaps 9.4-RELEASE?) will not have the old pkg_* tools. This seems a bit odd to happen in the middle of a series because of POLA, but we can't support the old package tools forever and FreeBSD 9.1-9.3 will have given you plenty of opportunity to migrate to the new package format and ease the upgrade to FreeBSD 10.x. 2) pkgng I think it has checksum checking on the files in the packages. Could pkgng detect the packages was being tampered? man pkg-check pkg check -s is used to find invalid checksums for installed packages. Or how can user authenticate that the package is build by FreeBSD? I don't think packages are signed yet, but this is permitted by the new pkg design and will hopefully happen before too long

Why OpenLDAP? Why not one of the other ldap implementations available in the ports? In particular, do any of them already have plugins for use with pam? OpenLDAP, nss_ldap, pam_ldap should be the stable. It was around for years and most Linux distro come with it. For Solaris, it comes with Sun Microsystems implementation of LDAP library. BTW, I see ISC Bind, Sendmail and Amd automounter is in base. Yes, but you're asking to move a major chunk of functionality into the base from ports. That doesn't really happen very often, for lots of good reasons. Those reasons are often used to suggest that the packages you just named be moved *out* of the base system, but that's not much easier than moving things into it. The other issue is - well, how much use is this for ports? After all, most of the servers you're going to install come from ports, so if they don't play here, then there's not much of a win. In the past, in my University. There are several computer labs. They run around 200 Solaris and Linux workstations. I guess the total number of students in the faculty is around a thousand. Of course LDAP SSO comes into play. 4. LVM and file systems As of FreeBSD 7.0, ZFS is ported. This is great as FreeBSD do not have LVM in the past. True, there's no volume manager per se. On the other hand, most of the functionality provided by a volume manager is available through the geom system. Frankly, geom is a lot saner than the volume managers I've dealt with. I am sure there is still room for improvement. For example: ZFS/UFS shrink support, native file system journaling. Um, is something wrong with gjournal? Or for that matter, soft updates (which solve the same problem that journaling does, only with lower overhead)? FreeBSD is an open source, volunteer driven project. A list of nice to haves is cool for your personal use, but if you want to actually make any of them happen, then you're the best person to do that. Either start coding yourself, or convince somebody else to do it (and you'll find cash offers work fairly well). Even then, it may not make it into the base system. Being available as a port is often considered sufficient, or it may be that your changes aren't considered appropriate for some other reason, like duplicating functionality that already exists. mike -- Mike Meyer [EMAIL PROTECTED] http://www.mired.org/consulting.html Independent Network/Unix/Perforce consultant, email for more information. ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED] Special deal for Yahoo! users friends - No Cost.

Re: can we use disk device for iscsi-target port?
My testing env is Vmware, the backend disks are new/empty. Here's my testing result: 1. OpenBSD 4.1 with iscsi-target compiled (I can't find it in the ports) It support disk slice directly, I use /dev/sd1c. 2. NetBSD 4.0-current with iscsi-target in base OS It support disk slice directly, I use /dev/sd1d. 3. FreeBSD 6.2 with iscsi-target port: When the new harddisk is added. It is empty and do not have any individual slice (only have /dev/da1). iscsi-target cannot use /dev/da1 directly (tested yesterday) /dev/da1c is gone in FreeBSD (since 5.0) I have tried to create a disk slice by fdisk (/dev/da1s1 and /dev/da1s1c is created).

Re: Backup problem for backup MySQL (a table 2GB)
The main problem is money. Buying a new product needs money. The old backup product (commercial) is scalable and is working fine with various OS. However it is outdated and is not supported anymore (unless we have a service agreement with the vendor of the backup product.) It consumes lots of space to do tar+gzip and split. I am thinking if I could copy all mysql files to another server (by ftp/ssh) periodically.

Feature request (pam/nss ldap, nsswitch ldap integration)
Hi First of all, I know that most committers or contributors contribute their work in their free time. I am not asking for any promise but I just want to discuss a possible improvement for FreeBSD. So my suggestion is: integrate pam_ldap, nss_ldap, nsswitch support with ldap and lookupd (ie LDAP client support) into the OS. Perhaps by default, the ldap support is off. It can be enabled by a switch in /etc/make.conf (like KERBEROS) FreeBSD has the above support in the ports. But I think it would be great if FreeBSD support LDAP out of the box. Just like Solaris and most Linux distro. The integration with LDAP is like the integration of OpenPAM, OpenSSH, AMD automounter and BIND in FreeBSD. Please express your view. Ignore me if my suggestion has no practical use or only beneficial to a small amount of people.
