[gentoo-user] dummy0 network interface
After a recent world update I have a new network interface in addition
to 'lo' and the real network interface ('eth0', now named 'enp1s4'):
# ifconfig dummy0
dummy0: flags=195UP,BROADCAST,RUNNING,NOARP mtu 1500
ether 2e:a2:4b:cb:f2:3f txqueuelen 0 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 51 bytes 19992 (19.5 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
# udevadm info -p /sys/class/net/dummy0
P: /devices/virtual/net/dummy0
E: DEVPATH=/devices/virtual/net/dummy0
E: IFINDEX=2
E: INTERFACE=dummy0
E: SUBSYSTEM=net
I'm using sys-fs/udev-210 on an ~amd64 with the predictable network
interface names.
Does anybody know where this dummy0 interface comes from?
Can I (or should I) disable or remove it?
thanks,

a recent world update means nothing to us, it coud have included
anything.

It's nothing to do with udev, it is a kernel feature, enabled by
CONFIG_DUMMY. You can disable it if you wish, or build it as a module in
which case the interface will not appear until you modprobe it.

You get this anywhere you choose but the easiest is to boot from a removeable media (CD, USB, etc). Booting the Gentoo minimal install CD (from CD/DVD or USB flash drive) is the canonical way to get to the point where you start following the steps in the handbook. On one recent install, I used systemrescuecd 4.xx, which gives you a nice minimal XFCE desktop with the Midori web browser you can use to read the handbook (and wander around the web while stuff builds). There was one step -- installing syslog-ng, I think -- where there was a glitch due to an environment variable set by srcd. Immediately after doing the chroot do the following command # export path= See below for more details http://forums.gentoo.org/viewtopic-t-921678-start-0.html http://forums.gentoo.org/viewtopic-t-786386.html Gentoo used to have a page[1] documenting the required deviations from the handbook to install from an arbitrary recent-glibc linux environment. Now it redirects to a wiki page[2] with roughly similar content. When installing from media other than the official gentoo minimal install cd, you should refer to the section currently labelled Installation from non-Gentoo LiveCDs in [2] to avoid surprises. In particular, I have several times seen people run into problems due to not properly adapting the instructions on mounting (thus missing /dev/pts in the chroot) and cleaning the environment prior to chrooting (thus ending up with incomplete PATH or having various variables set that break the build systems for packages bundling gnulib). (Sorry for arrogantly repeating some of the information you provided, but since forums and mailing list entries get archived and are searchable forever and are not updated, I feel it is prudent to provide pointers to resources that have a greater chance of staying relevant.) 1: http://www.gentoo.org/doc/en/altinstall.xml 2: https://wiki.gentoo.org/wiki/Installation_alternatives -- eroen signature.asc Description: PGP signature

I don't know if it is built as a default, or if you need to emerge dev-php/phpmd. In any case, I wouldn't expect this to have anything to do with webDAV. Is that the mess detector? If so it's keyworded and I'm sure I haven't installed it before, whereas I had owncloud running ok before my hard disk failure. That failure caused me to rebuild from scratch on its SSD replacement, because so many disk-unreadable errors came up at the end that I didn't trust anything stored on it. Have you manually disabled webDAV in your apache configuration? You will need to set 'Dav Off' under the entry for your Directory /var/www/owncloud. You will also need to check that you have *not* enabled authentication at apache level because this is managed by the php code and you have also set 'Satisfy Any' under 'Allow from all'. I've included this stanza in default_vhost.include: Directory /var/www/localhost/htdocs/owncloud Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all Satisfy Any # Dav Off /Directory With that # mark omitted I get this: # /etc/init.d/apache2 start * apache2 has detected an error in your setup: Syntax error on line 70 of /etc/apache2/vhosts.d/default_vhost.include: Invalid command 'Dav', perhaps misspelled or defined by a module not included in the server configuration * ERROR: apache2 failed to start So the WebDAV module is not available, which makes sense because it isn't specified in /etc/conf.d/apache2. With the # present I still get the error from owncloud. Apache was remerged overnight; PHP has just finished, but reloading Apache still gives me the owncloud WebDAV error - so PHP isn't to blame. Finally, increase verbosity in apache to see what access errors it reports. Good idea. Thanks again Mick. I've just found something odd.

[gentoo-user] glibc build problem
he guys. I'm having trouble compiling glibc. No matter I tried with binutils 2.23 2.24. or - live version, I got ld internal error in x86_64_relocation . And the same error repeated with glibc-2.18 and glibc-2.19 . Don't know why . The google bring me a old bug report about x86_64_relocation internal error when used conjunction with IFUNC, but that doesn't seems to be related with mine problem. When I first try to update glibc to 2.18, it's fine. but then the attempt to update glibc to 2.18-r1 failed with ld internal error. This error remains with glibc-2.16-r2 and glibc-2.19, regardless of binutils version.
