enabling GPT (was Re: what to do with a uefi hp pavillion 10-f014au?)
David Coppa suggests a custom kernel with the GPT option turned on. I'm thinking along the lines of (1) compiling the custom kernels (GENERIC, GENERIC.MP, and RAMDISK with the option GPT turned on) and (2) making a bootable USB drive with that, (3) backing up the current installed openbsd system to another USB drive, probably a USB connected rotating HD. (4) then resurrecting MSWindows from the recovery disks and shrinking the MSWindows partition, and (5) using the USB drive to try installing to a GPT partition. What else would I need besides building the GPT enabled kernel? Do I need to install additional packages, or apply the google soc diffs as patches to things? And what kind of odds do I have of being able to dual-boot (using the BIOS boot manager, I suppose) openbsd on such a system?

Re: Blob-free OpenBSD kernel needed
I got the idea of this post, finally: one guy lacking basic knowledge pops in and talks in confusion about some non-free parts inside OpenBSD's kernel. Few threads more and another one is posting a suggestion of liberation. Cheap ads. I am convinced now the free idea got distorted reaching the boundary of paranoia. For the OP: Was openssl able to satisfy you because it was free, open, source code available, GPL sexy version on? Was it free of bugs, trojans, backdoors, etc? A time will come when folks will appreciate quality code and people behind it. Nah, I really don't think so!

Re: partition alignment and advanced format drives
i got curious how visible this speed difference would be, so while i was setting up the disk anyway, i made this unscientific experiment. some modern linux distros (and win7) use 2048 sectors as offset for their first partition, an alignment of 1MB. openbsd's fdisk uses 64. one thing it does not do is creating partition sizes divisble you have confused yourself. 1. openbsd default offset: [64] 280.28 real 6.32 user 7.59 sys 2. linux style offset: [2048] 280.78 real 6.99 user 6.01 sys So no difference at all between those two. 3. non-aligned offset: [63] 339.51 real 4.46 user 5.63 sys quite a difference. Quite a difference WHAT?? Noone uses a non-pow2 alignment. Everyone aligns -- everyone, except you, in this bogus test. This is not a matter of science. Your message is very confusing since the length of it subtly hints OpenBSD is doing something wrong, and we are not. one thing fdisk does not seem to do yet: generate partition sizes divisible by 8. while maybe not necessary on an openbsd only system, in multiboot configurations it might be a matter of being a good neighbour in cases where openbsd is not the last partition on the disk. So you are the one concerned about this. And you already have a setup to test with. So why don't you try writing a diff -- instead of trying to pawn your problem off on someone else?

Hello. I have noticed that the ksh and sh manpages don't make reference to the file /.profile, which I understand to hold the default shell variables if the other source files listed on the manuals don't exist. The current FILES secion of SH(1): FILES ~/.profile User's login profile. /etc/profile System login profile. /etc/suid_profilePrivileged shell profile. /etc/shells Shell database. The current FILES section of KSH(1) FILES ~/.profile User's login profile. /etc/ksh.kshrc Global configuration file. Not sourced by default. /etc/profile System login profile. /etc/shells Shell database. /etc/suid_profilePrivileged shell profile. I noticed that when none of this files exist, variables for the shells are populated from somewhere else. (/.profile). My suggestion is to update the docummentation, and add /.profile to the FILES section of the man pages. Or just move /.profile to /etc/profile if feasible. Is there any reason for having a configuration dotfile in / ?
Re: GROUP CHANGED
Groups and users are actually just numbers, the mapping to names happens in the /etc/passwd and /etc/group files. On Linux, user 0 is 'root' and group 0 is 'root'. On BSDs, user 0 is 'root', but group 0 is 'wheel'. Check the /etc/group file on both systems, and you will see. Bernd On 14/06/15 15:46, Max Power wrote: Thank You Gilles for Your reply.

partition alignment and advanced format drives
i was putting a 2.5 500G WD disk into a usb enclosure and i noticed that instead of technical information they used to put there (chs, lba, etc) most of the space was taken up by a notice about this being advenced format drive, and how speed will suffer if used with windows xp, etc, without partition realignment. and it had jumpers -- i haven't seen jumpers on drives for ages. IIUC, the jumpers can be used to indicate an offset-by-one: make LBA 63 aligned on hardware sector. quite the backwards compatibility. i got curious how visible this speed difference would be, so while i was setting up the disk anyway, i made this unscientific experiment. some modern linux distros (and win7) use 2048 sectors as offset for their first partition, an alignment of 1MB. openbsd's fdisk uses 64. one thing it does not do is creating partition sizes divisble 1. openbsd default Disk: sd3 geometry: 60801/255/63 [976773168 Sectors] Offset: 0 Signature: 0xAA55 Starting Ending LBA Info: #: id C H S - C H S [ start:size ] --- 0: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused 1: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused 2: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused *3: A6 0 1 2 - 60800 254 63 [ 64: 976768001 ] OpenBSD partition: [a] offset: [64] size: [976768001] FS type: [4.2BSD] Rounding size to bsize (64 sectors): 976768000 # time newfs /dev/rsd3a /dev/rsd3a: 476937.5MB in 976768000 sectors of 512 bytes 586 cylinder groups of 814.44MB, 26062 blocks, 52224 inodes each super-block backups (for fsck -b #) at: ... 972425408, 974093376, 975761344, 280.28 real 6.32 user 7.59 sys 2. linux style Disk: sd3 geometry: 60801/255/63 [976773168 Sectors] Offset: 0 Signature: 0xAA55 Starting Ending LBA Info: #: id C H S - C H S [ start:size ] --- 0: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused 1: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused 2: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused *3: A6 0 32 33 - 60800 254 63 [2048: 976766017 ] OpenBSD partition: [a] offset: [2048] size: [976766017] FS type: [4.2BSD] Rounding size to bsize (64 sectors): 976766016 # time newfs /dev/rsd3a /dev/rsd3a: 476936.5MB in 976766016 sectors of 512 bytes 586 cylinder groups of 814.44MB, 26062 blocks, 52224 inodes each super-block backups (for fsck -b #) at: ... 972425408, 974093376, 975761344, 280.78 real 6.99 user 6.01 sys 3. non-aligned Disk: sd3 geometry: 60801/255/63 [976773168 Sectors] Offset: 0 Signature: 0xAA55 Starting Ending LBA Info: #: id C H S - C H S [ start:size ] --- 0: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused 1: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused 2: 00 0 0 0 - 0 0 0 [ 0: 0 ] unused *3: A6 0 1 1 - 60800 254 63 [ 63: 976768002 ] OpenBSD partition: [a] offset: [63] size: [976768002] FS type: [4.2BSD] Rounding size to bsize (64 sectors): 976768001 # time newfs /dev/rsd3a /dev/rsd3a: 476937.5MB in 976768000 sectors of 512 bytes 586 cylinder groups of 814.44MB, 26062 blocks, 52224 inodes each super-block backups (for fsck -b #) at: ... 972425408, 974093376, 975761344, 339.51 real 4.46 user 5.63 sys quite a difference. one thing fdisk does not seem to do yet: generate partition sizes divisible by 8. while maybe not necessary on an openbsd only system, in multiboot configurations it might be a matter of being a good neighbour in cases where openbsd is not the last partition on the disk. -f -- i'm so close to hell i can almost see vegas!

sogo, httpd(8) and the rewrite need
Hi,
I was going to install SOGo on OpenBSD 5.7 using the native httpd(8).
In the readme, there are configuration examples for nginx and
apache-httpd-openbsd. Nothing for the new httpd.
There are rewrite/redirect features that I can’t figure out how to setup with
httpd(8).
nginx example:
location = /principals/
{
rewrite ^ http://$server_name/SOGo/dav;
allow all;
}
apache-httpd-openbsd example:
RedirectMatch ^/principals/$ http://127.0.0.1:8800/SOGo/dav/
Is it possible to achieve such feature with httpd and/or relayd ?
Thanks.
