Not necessarily. There are several ways to work around this problem
that I've used with great success. In order of my preference, they are:
1. I run squid on my laptop, bound only to the localhost interface and
with ACLs that only allow localhost to use it as a general-purpose
proxy, then I login to the remote host with a port forward and run
cpanp (or cpan) with a proxy configuration...
ssh -R 3128:localhost:3128 server.address
server% http_proxy=http://localhost:3128 cpanp
2. If I'm at a client site where my laptop won't have outgoing access
either, then I run apache on the laptop, and use CPAN::Mini to make
myself a local mirror of CPAN before I go...
minicpan -l /var/www/html/minicpan -r http://some.cpan.mirror/
ssh -R 8080:localhost:80 server.address
server% cpanp (and use http://localhost:8080/minicpan as the mirror
3. As a last resort, if the site is so paranoid that ssh forwarding is
locked down too, then I still have a fallback...
rsync -essh -avz /var/www/html/minicpan some.secure.host:minicpan
If you write your own mirroring tool instead of using the cpanmini
script, you can even exclude stuff from your local mirror...
remote => 'http://some.cpan.mirror',
local => '/data/minicpan',
force => 0,
trace => 1,
skip_perl => 1,
path_filters => [
module_filters => [
CPAN::Mini only mirrors the most recent version of each module, so the
size is much smaller than you might expect (I believe a minicpan
mirror can still fit on a CD-ROM, although I haven't checked that
