I work under a current Debian 4.0 (AMD64/stable) and try to compile a current Gentoo in a chroot'ed environment. Portage fails to resolve host names correctly after it has been updated. /etc/resolv.conf is set correctly. # emerge --version Portage 2.1.4.4 (default/linux/amd64/2008.0, gcc-4.1.2, glibc-2.6.1-r0, 2.6.24.6 x86_64) # emerge -f --newuse world Calculating world dependencies... done! >>> Emerging (1 of 1) sys-devel/gcc-4.1.2 to / >>> Downloading 'http://distfiles.gentoo.org/distfiles/gcc-4.1.2-patches-1.1.tar.bz2' --2008-05-17 23:43:46-- http://distfiles.gentoo.org/distfiles/gcc-4.1.2-patches-1.1.tar.bz2 Resolving distfiles.gentoo.org... failed: Temporary failure in name resolution.

Hi, coud you ping anything else appart from that? Did you try to ping the IP adress? Can you post your /etc/conf.d/net and the relevant dmesg, lscpi and ifconfig output??? Whats the Gentoo and Kernel version you are using? Thanks, Karsten
Hi, > coud you ping anything else appart from that? Yes, virtually everything. > Did you try to ping the IP adress? Yes. Works. > Can you post your /etc/conf.d/net and the relevant dmesg, lscpi and ifconfig output??? Since it is a production Debian system and just a chroot'ed Gentoo environment, which actually has neither kernel nor net config, I doubt that would help. In the chroot cage: Everything works, until portage makes some environmental changes. Why? For what reason? If there is some sandbox in order to fetch files, where is it? > Whats the Gentoo and Kernel version you are using? Gentoo is the Gentoo of today, and kernel is Linux superlupo 2.6.24.6 #1 SMP Sat May 3 22:19:46 CEST 2008 x86_64 GNU/Linux
Ahem, sorry, forgot to say: "emerge --sync" works perfectly. Problems only when trying to fetch files. Most of the files are already there, so "emerge system" worked perfectly, too.
First of all, I would give env-update a try and source /etc/profile After that we could probably narrow it down to only wget wont connect to the mirror? Can you wget the file manually? If you have a proxy in place did you specify it in the /etc/wgetrc or ~/.wgetrc??
env-update and . /etc/profile done, no change. wget manually invoked from command line works perfectly. There are no private settings yet, this is simply a plain Gentoo (i.e. stage3-amd64-2008.0_beta2) without anything changed, except for /etc/localtime, /etc/resolv.conf, and /etc/make.conf. "emerge --sync" and "emerge system" are done, now I want to emerge the rest... /dev and /proc are mounted --bind from the host system. There are no proxy settings required, so that isn't the problem.
I wondering if your "working" wget is not properly bound to portage. Try: 1. which wget 2.set the FETCHCOMMAND var in your /etc/make.conf example make.conf: # Fetching files # ============== # # Default fetch command (5 tries, passive ftp for firewall compatibility) #FETCHCOMMAND="/usr/bin/wget -t 5 --passive-ftp \${URI} -P \${DISTDIR}" #RESUMECOMMAND="/usr/bin/wget -c -t 5 --passive-ftp \${URI} -P \${DISTDIR}" # # Using wget, ratelimiting downloads #FETCHCOMMAND="/usr/bin/wget -t 5 --passive-ftp --limit-rate=200k \${URI} -P \${DISTDIR}" #RESUMECOMMAND="/usr/bin/wget -c -t 5 --passive-ftp --limit-rate=200k \${URI} -P \${DISTDIR}" #
# which wget /usr/bin/wget # ls -d /var/db/pkg/*/wget* /var/db/pkg/net-misc/wget-1.11.1 FETCHCOMMAND set... Doesn't work. Sorry. The error message: "Temporary failure in name resolution" means: It is there, it is being executed, but for some reason, the DNS settings disappear. What can it be but a broken sandbox mechanism?
"Does it work if you put distfiles.gentoo.org and its ip address in /etc/hosts?"
Yes, that works.
(In reply to comment #8) > "Does it work if you put distfiles.gentoo.org and its ip address in > /etc/hosts?" Of course that works. @yanestra: You didn't show the $YOUR_CHROOT/etc/resolv.conf yet. Also, did you try a simple `wget http://distfiles.gentoo.org/distfiles/gcc-4.1.2-patches-1.1.tar.bz2' yet? Also, your emerge --info is missing. I would also like to know if /proc and /dev are mounted inside the chroot. By the way, it's considered inappropriate to use our distfiles master. Please find a local mirror[1] and start using that instead. [1] http://www.gentoo.org/main/en/mirrors.xml
@Jeroen resolv.conf contains only one line: nameserver 192.168.1.1 I tried a manual wget, and it worked (which I already had written). Jeroen, I suppose I may use the distfile master for testing purposes, maybe even with your permission. Thank you very much. emerge --info will be posted when possible (it's not right now).
Hi, I'm confronted with the same problem in a xen-domU. I copied a working domU, bootet the copy and wasn't able to fetch any sources - running wget manually worked. The problem seems to have sth. to do with the userfetch-FEATURE. If I put "-userfetch" in my make.conf, everthing works fine. The permissions of the distdir are correct (since they work on the other machine without problems). Any suggestions?

i'm guessing that was indeed the source of your troubles
