Parallel downloads can be a bit harsh on the servers, and some will fail (eg. uclibc.org) in some cases. Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr>

Normally, crosstool-NG will try to download missing tarballs (or
|
|
checkout from CVS/SVN...).
|
|
If you do not have network connectivity when you run crosstool-NG,
|
|
and some files are missing, it can be a long time before crosstool-NG
|
|
fails.
|
|
|
|
Saying 'y' here will prevent crosstool-NG from downloading missing
|
|
files, thus failing early so that you don't get stuck.

If you have a machine on your LAN that mirrors some of the needed

tarballs, you can say 'Y' here, and configure adequate values in
|
|
the following options.
|
|

Obviously, nothing prevents you from using a mirror that is in fact
|
|
*not* on your LAN, for example on another subnet of your company's

network, or a mirror on the Internet.

I (Yann E. MORIN) have set up such a mirror to host snapshots of
|
|
some components, when those snapshots are volatile on the upstream
|
|
servers. The mirror is *slow*, because it is hosted behind an ADSL
|
|
line. For the time being, I haven't set up bandwidth limitations,
|
|
but should the mirror be abused, I will. Please avoid using my
|
|
machine when you can... Also, no guarantee is made as to its
|
|
availability. Use at your own risks.
|
|
|
|
The mirror is available at:

From the curl manual:
|
|
Maximum time in seconds that you allow the connection to the server to take.
|
|
|
|
The scenario is as follows;
|
|
- some enterprise networks have firewalls that prohibit FTP traffic, while
|
|
still allowing HTTP
|
|
- most download sites have http:// equivalent for the ftp:// URL
|
|
- after this number of seconds, it is considered that the connection could
|
|
not be established, and the next URL in the list is tried, until we reach
|
|
an URL that will go through the firewall, most probably an http:// URL.
|
|
|
|
If you have a slow network, you'd better set this value higher than the default
|
|
10s. If you know a firewall is blocking connections, but your network is globally
|
|
fast, you can try to lower this value to jump more quickly to allowed URLs. YMMV.
|
|
|
|
Note that this value applies equally to wget if you have that installed.

If you have aria2 installed, then it will be used to download files.
|
|
Aria2 can split the download in chunks, and download those chunks in //
|
|
which can be interesting to speed up the download.
|
|
|
|
On the other hand, using many chunks, or even chunking in general, may
|
|
be seen by some site admins as being kind of unfair, or even as a DoS.
|
|
That's why the range of acceptable values is [1..10], and the default
|
|
is 5 (aria2's default).
