Exactly. NIX_REMOTE is set to daemon and you need to unset it so that the nix*-utils inherits those vars: export NIX_REMOTE="" export http_proxy=$1 meaning that root gets a HTTP proxy to communicate through and that she shan't make RPC calls to the nix-worker but build herself. This interim proxy subject can be found at: * https://lastlog.de/wiki/index.php/Nixos_configuration.nix#nixos_with_proxy - You also need to unset binary-caches since those fetches didn't honour the proxyvars when I needed an interim proxy. * https://github.com/edwtjo/nixin/blob/master/nixin#L103-L124 - My own hack. Example of disabled binary-caches when setting or unsetting a system proxy. Also note that I don't recommend using that script, it is just an example usage. > > Looking around the manual, I have found nix.proxy configuration > string. I have ended up with a /etc/nixos/configuration.nix like that: nix.proxy will set the http_proxy upon the next activation, which happens after a nixos-rebuild switch. You need to use an interim proxy to actually do that, as described above. You also don't want to update the build expressions, nix-channel or git fetch, in order to keep the system switch rebuild small. > > { config, pkgs, ... }: > > { > imports = [ <nixos/modules/installer/virtualbox-demo.nix> > <nixpkgs/nixos/modules/services/misc/nix-daemon.nix> > ]; > > nix.proxy = "proxy-host.com:3128"; > > } > > However nixos-rebuild switch fails in the same way as nix-env -i: > > building Nix... > building the system configuration... > download-from-binary-cache.pl: still waiting for > ‘http://cache.nixos.org/nix-cache-info’ after 5 seconds... > download-from-binary-cache.pl: could not download > ‘http://cache.nixos.org/nix-cache-info’ (Curl error 7) > these derivations will be built: > /nix/store/17s184bdsmnqa0vpwxmyj58i3a2n8flz-dbus-conf.drv > /nix/store/2jwpim2m9f4yhi1ds0rqqcl6h623v0b5-stdenv.drv > /nix/store/3xbm6viqjdpznhxxxqpsirlfjz0b64lw-bzip2.drv > ... > /nix/store/zw9nnsyygzz72j5b3j5zw4bknzkcbcdf-docbook-5.0.zip.drv > building path(s) `/nix/store/4fxls0b5l7c3kdd8idbzr6cp823iip37-bzip2' > downloading http://tarballs.nixos.org/stdenv-linux/i686/r24519/bzip2 > into /nix/store/4fxls0b5l7c3kdd8idbzr6cp823iip37-bzip2 > % Total % Received % Xferd Average Speed Time Time Time > Current > Dload Upload Total Spent Left Speed > 0 0 0 0 0 0 0 0 --:--:-- 0:02:07 --:--:-- > > > > Thank you in advance. > _______________________________________________ > nix-dev mailing list > [email protected] > http://lists.science.uu.nl/mailman/listinfo/nix-dev Regards
