?

Best regards,

Holger

Setting global variables is a solution, but the real problem is that the import does not support proxy. 
To do so you could patch the import file PubMedID.pm and add the method LWP for fetching the files (same as DSpace.pm). 
Once you have done that, add 

https://github.com/eprints/eprints/pull/296/files

to use proxy with LWP.

Best regards,

Denis

Hi,

I think you might be able to set the proxy in the env e.g.:

export http_proxy='http://user:password@proxy-server:3128'

export https_proxy='http://user:password@proxy-server:3128'

export ftp_proxy='http://user:password@proxy-server:3128'

In the past (for a reason I can’t remember now), I had to do something like this:

http://serverfault.com/questions/589340/configuring-apache-web-server-to-use-the-http-proxy-environment-variable

- but that was on an old Solaris server…

Cheers,

John

No, that is not the problem - the extension is installed and works fine. I have changed our firewall config, so eprints can communicate without a proxy, but this is only a workaround.

Do you have any other idea?

It seems, from your log message, that the problem is with your perl installation: you are missing the extension XML::LibXML

Hi Holger,

I have created in cfg/cfg.d a file called proxy.pl <http://proxy.pl>  with the line:

$c->{proxy} = 'http://proxy.yourproxy.org:yourport';

and everything works fine.

Hi @ all,

my new eprints server is behind a firewall in a DMZ. If i will import Items from Pubmed ID i get an error message. 

-- error : unreachable network --

I think eprints dont know how to communicate outside and i have to set a proxy.

So how can i tell eprints to use a proxy server?

OS: Cent OS 6.7

Eprints Version 3.3.15

King regards,

Holger
