Subject: [ECOS] eCos on ubuntu - general download problem

All,

I'm a relative newbie to linux and definitely to the eCos operating
system.  I have been getting a particular error while trying to download
the software (using the ecos-install.tcl) that I can't seem to get
around and was wondering if anyone could help.  Here's what I did in
detail:

Download failed. Perhaps you need to set a proxy to connect via a
firewall?

Configure a proxy? [Y/n]
</copied in>

I don't know how to configure a proxy on linux (have tried to look it
up) but no dice so far.  I've tried some intelligent things and I've
tried every entry on the ftp list.  The problem may be that I'm doing
this connected to my universities network.  If anyone can help, even a
suggestion, it's appreciated.  This may be a common newb problem worth
remembering.

David,

You need to do something like:

$ export http_proxy=http://wwwcache.university-address:8080
$ export ftp_proxy=http://wwwcache.university-address:8080

Do this before runing the ecos-install.tcl script. Or when it asks if
you need to set a proxy then answer yes and enter the proxy address as
above where 8080 is the proxy port number.

Note that it will only last for your current console session.
Get the exact proxy address from Internet explorer or other web browser
network settings if you don't know it.
You can set this in your .bashrc file or .bash_profile to make it
permanent, but if you are using Ubuntu then there is usually a better
way to set this globally in one of the Administrator or preference
settings on the Gnome panel.

Hope this helps,

Steven
