Re: Fwd: kfreebsd dropped as an official release architecture for Debian Jessie

In one point Hubbart is a bit unkind to FreeBSDs init scripts. For a while now they are now "ahead" of old-fashioned sysV where the number S## determines the order. rcorder orders them at run time before running them. E.g. nfsd: # REQUIRE: mountd hostname gssd nfsuserd mountd: # REQUIRE: NETWORKING rpcbind quota rcpbind: # REQUIRE: NETWORKING ntpdate syslogd ntpdate: # REQUIRE: NETWORKING syslogd So this describes a logical order for nfsd and dependencies. Obviously some order is needed but they all come after a milestone NETWORKING and syslogd. syslogd_enable ="NO" makes the later a NOP. pppoed has # REQUIRE: NETWORKING so it could run in parallel. Yes, there is inetd, and there is cron.. (something else?) and there is a risk of having things in parallel (needeing semaphores). Ansd there are events as e.g. a USB device plugged in and caught by devfs etc. I am pretty sure that will be dealt with in a sensible way. systemd is a bit like our office renovations at the moment. [Slightly made up] "There is a cable in the way" "Just cut it" "Don't worry we go wireless". And a few days later: "Well, we need this on an Ethernet cable." "Don't worry, I still have a piece of string and a band aid" I just helped someone on the German mailing list with boot problems under OpenSUSE. He had /home coming from an iSCSI target. It just did not boot. He could not figure out how to fix the sequence so it worked, and started to hole it through the boot.local and rc.local scripts. This are fallbacks which are more or less obsolete for twenty years but needed as a life support for him. Regards Peter

New OpenSUSE install- issues with encryption and LVM
by Andrew Greig 27 Nov '14

27 Nov '14

Hi All, A few weeks backI tried to install the 32bit version of OpenSuse 13.2 on a Toshiba A100 machine. It did not go well. So tonight I have had another crack at an install and I would like to get back to a clean drive, but there are a couple of encrypted LVM partitions which I cannot delete. It only has a 120Gb HDD so I don't want to sacrifice 30Gb for these two partitions. On trying to delete a partition, I get the message "The selected partition is used by volume group "/dev/system" To keep the system in a consistent state, the volume group and its logical volumes will be deleted. Then ... Delete partition /dev.sda1 and volume group ?dev/system now? Then clicking on delete does nothing. Everything remains intact. how do I overcome this, please? Andrew Greig

Possibly a simpler way out is to check to see if the low level tools fdisk or cfdisk is avaible on the disk. Neither of these tools particularly fdisk are very intelligent and they will erase any partition with only a single warning. Lindsay

An apt-get question
by Allan Duncan 26 Nov '14

26 Nov '14

As a happy user of the rpm system I find myself needing to bend apt-get's ear. On a Pi I got sick of having 3 versions of cpp so I just asked synaptic to remove the lot and then installed just 4.8. This worked fine except I found that I needed to make symbolic links from cpp to cpp-4.8 etc. I now need to install libtool but synaptic wants to also install cpp (-4.6) without an option. I figured I could tell apt-get to forget about cpp and just get on with it (ie --nodeps in rpm), but it doesn't seem to have such an option. I have hazy memories of hacking a file somewhere to make the problem go away by changing the cpp deps. Suggestions please.

RedirectMatch problem
by Russell Coker 25 Nov '14

25 Nov '14

RedirectMatch ^/wws/subrequest/(.*)$ /cgi-bin/mailman/listinfo/$1 [L,R=301] Apache on the new server is refusing to start when the above config line is enabled for lists.luv.asn.au. Any idea why? According to my basic tests the mailman web pages are working well, so maybe it's not needed anyway. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

adsl modem that gets power over USB
by James Harper 24 Nov '14

24 Nov '14

I've replaced my home router with a little laptop, and it's working great. Does anyone make an ADSL modem that can be run (and powered) via USB? Most have USB ports but I suspect can't use it as a power source. This would allow my internet connection to stay up during the power outages that get more frequent out here once fire season starts. Thanks James

ZFS compression - looking for space savings
by Peter Ross 23 Nov '14

23 Nov '14

Hi all, I want to reorganize some backups and use ZFS snapshots copied to a "backup NAS" (I am having). Traditionally some zfs were sent as a .tgz to the NAS. I want to use ZFS compression on the box instead and look for the best method to compress it. Space savings are important, speed isn't. Below the man page describing the compression methods available. Do you have experience to recommend a method working well? I do not want to "muck around" and change too much because it is Terabytes worth of data and I do not want to reconfigure too often. I do not use compression on my production systems a lot so I do not have too much experience with it. I have a few "not frequently used/non-critical" filesystems with lz4 - but that's it. Speed-wise it did not seem to matter much compared to uncompressed filesystems (but I did not benchmark properly) Thanks for any advice Peter compression=on | off | lzjb | gzip | gzip-N | zle | lz4 Controls the compression algorithm used for this dataset. The lzjb compression algorithm is optimized for performance while providing decent data compression. Setting compression to on uses the lzjb com- pression algorithm. The gzip compression algorithm uses the same com- pression as the gzip(1) command. You can specify the gzip level by using the value gzip-N where N is an integer from 1 (fastest) to 9 (best compression ratio). Currently, gzip is equivalent to gzip-6 (which is also the default for gzip(1)). The zle compression algo- rithm compresses runs of zeros. The lz4 compression algorithm is a high-performance replacement for the lzjb algorithm. It features significantly faster compression and decompression, as well as a moderately higher compression ratio than lzjb, but can only be used on pools with the lz4_compress feature set to enabled. See zpool-features(7) for details on ZFS feature flags and the lz4_compress feature.

Varnish :80 New Zealand Apache Problems
by Piers Rowan 23 Nov '14

23 Nov '14

Hi All, This is a strange one. Ages ago we suddenly had NZ visitors complaining about time outs and white screens for our web apps. Noting else was broken except the people across the ditch (and a few other overseas customers). After testing and trying a vast number of things we put up varnish and told them to connect on port :6xxx and hey presto it all went back to normal. We did this for a few months and then decided to move everything on :80 through varnish. The speed improvement is great. Love it. Amazing. And now we have the NZ clients complaining that things are dropping out and whitescreening again. Is there a great firewall of Australia on port 80? How can one service on port :6xxx work flawlessly and then when moved to :80 kill overseas users? Really this is doing my head in. I am faced with changing everything back (and removing varnish and the speed it gives) and getting the NZ folks to use a weird port again. Clues appreciated. Cheers Piers

LUV server etc
by Russell Coker 21 Nov '14

21 Nov '14

The old LUV server has now been replaced. Due to multiple hardware problems (drive errors and CPU/RAM problems) I had to do a rush job. If you see this then the mailing lists are now working. The web site isn't working yet, I'm still trying to get it going. Any suggestions appreciated. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
