Do you use a proxy for normal browsing? If so, you can set the proxy 
in /etc/wgetrc.

If your proxy don't let ftp pass, use

torify

Please try to avoid doing this with large packages. Tor is a distributed
net built by volunteers. Flooding it with large downloads is neither
nice nor fast.

I'd say, try http.

Jeez. You didn't read the original posting, did you? It's FTP, period.

I still advise to set the proxy in /etc/wgetrc.

It's FTP, which is blocked by the firewall, so use only HTTP mirrors
in /etc/make.conf. There is no requirement to use FTP for downloads. If
rsync is also blocked, use emerge-webrsync to update the portage tree
over HTTP.

 export ftp_proxy=XXX.XX.XXX.XX:80 && emerge -uaDv world, should do what 
you're after.  You can also try export http_proxy of course.  It assumes that 
you know the LAN IP address of your web gateway/firewall at work - i.e. that 
your work's MSWindows configuration allows plain users to view the MSIE 
Internet Settings, or your sysadmin will let you know what the address is.  If 
not, boot a LiveCD on a works computer, mount its MSWindows C:\ drive and 
search for "proxy".  It should lurk somewhere in the registry settings.  
BartsPE CD will also help you find that, as it can search natively the 
registry.

BTW, if this is anything like my work, then only outbound connections to port 
80 are allowed and rsync will not work.  Follow the webrsync advice above.

HTH.

Hi,

You should also set RSYNC_PROXY to "hostname:port" in order for "emerge
--sync" to work.

I've tried that and had no success behind my work's firewall, but the OP may 
be luckier.
