Automated installer 2.7.7 - network unreachable - recommendation

Dear Hplip,

I'm maintaining a Pclinuxos network with 27 computers - and tried the HPLip 2.7.7 automated installer. It failed with the message Network unreachable - and yet the network is fine.

Apparently the installer is pinging www.google.com - and this is impossible either from my Linux at home, directly from my pix - or from any of our PClinux boxes.

My workaround was to alter the hosts file to let www.google.com point to localhost during the installation. My recommendation is to point the ping to one of HP's servers that is replying to pings.

The reason I write this, is because of the large number of posts I've read on the subject.

The installation by the way - went fine after this hack.

I will do the same at work tomorrow to see if printing bitmaps from our KDE applications is faster after this version update. An image prints in 30 seconds using guthenprint and 5-10 minutes using any KDE application using HPLip 1.6.9,

we use Linux to print on a extremely efficient HP5550n printer using JetDirect,

thanks,

Re: Automated installer 2.7.7 - network unreachable - recommendation

Hi, Martin-

Is the reason that pinging google.com not working because you do not route ping packets or that you do not allow access to outside servers?

In 2.7.9, I have changed the network check to first attempt an HTTP get (using curl or wget) of http://www.google.com and if that fails it will try to ping www.google.com. The reason we chose not to use an HP server, is that in our testing, we had several cases where pinging an HP server would fail. I don't know if they have pinging turned off or what the issue was, but we felt that google.com would be pretty universally accessible to our users.

Would these commands succeed on your network?:

wget --timeout=5 http://www.google.com

or:

curl --connect-timeout 3 --max-time 5 http://www.google.com


Thanks,

Don
