Is there a proxy between my VM and the open web?

[Burns, Eric]

Hi!  I have two VM resources on GENI, and I’m trying to install my node.js server on them.  On both, “npm install” errors out trying to fetch the prerequisite libraries.  Usually this is due to internet connectivity issues, and can be caused by a proxy (if I don’t have npm set up to use that proxy).

 

Do the resources have a proxy between that VM and the open internet?

 

A curl from one resource (pcvm2-6.instageni.nysernet.org) showed that it could reach the prerequisite URLs fine (which would be consistent with the idea that I have not set up npm correctly for a proxy).

 

On pcvm2-6.instageni.stanford.edu, though, I wasn’t able to install curl because I get 404 errors trying to do so (on URLs that work fine on my machine).

 

Anyone have any ideas of why this could be happening?

 

Thanks!

Hi. I logged into your VM and tried wget and ftp, both worked fine.
Maybe you are seeing a transient problem with site you are trying to
access?

Hi Eric,

This seems to just be an npm configuration issue.

I think I was able to reproduce your issue (are you seeing something like [1]).

Googling "npm install fails" took me to:

http://stackoverflow.com/a/13119867/1804086

So I did:

$ npm config set registry http://registry.npmjs.org/

And now I can install a packet using npm:

$ npm install sax

npm http GET http://registry.npmjs.org/sax

npm http 200 http://registry.npmjs.org/sax

npm http GET http://registry.npmjs.org/sax/-/sax-0.6.0.tgz

npm http 200 http://registry.npmjs.org/sax/-/sax-0.6.0.tgz

s...@0.6.0 ./node_modules/sax

Could you try that?

Thanks,

Sarah
