Altera Installer 11.1 Build 173, linux

Altera_Forum · ‎02-17-2012

Aloha,

installer gives error right at begining, "Error connecting to the internet, check your proxy information ...." I'm connected to internet, no proxy needed. outgoing ip/icmp ip/tcp, and "telnet google.com 80" all work fine. Would anyone know what method the installer uses for determining connection to the internet? I would assume hacking the installer to make it work would be illegal?

thanks,

Juan.

Looks like a failing DNS lookup.

umm.

NXDomain. but the akamai.net host exists.

but 192.168 address doesn't have a reverse reference...

but why does it bother?

Altera_Forum · ‎02-18-2012

No. dns doesn't seem to be the cause. to be sure, I created reverse entries in my hosts file for the missing in-addr.ptr records. And it still doesn't work.

The problem exists between these two system calls:

[pid 1063] mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb7220000

[pid 1063] write(1, "DOWNLOAD_FAILED:4 | Error:IOErro"..., 88) = 88

mmap2 returned a pointer, so that worked, and yet the Installer decides that it's failed.

Perhaps the content of the data mapped into memory was not what the installer expected.

I think I'd have to unpack and debug the installer to pursue this issue any further.

It's disappointing cause I really wanted to get some work done with my new FPGA kit this weekend.

It seems that at least some of the Installer's executables, or the resolver library it's linked and distributed with are buggy; at least on my machine, Debian linux; wheezy/sid; 2.6.39-2-686.

In particular: ./bin/quartus_dl whom the installer uses as a littler helper for downloading from http.

When quartus_dl resolves the IP for download.altera.com, it expects an ip, get's a CNAME, and then decides it's failed to connect. As a temporary solution I've used:

echo "128.171.28.7 download.altera.com" >> /etc/hosts

Now the installer seems to work.

Thank you so much.

I would like to add a few things,

In addition to download.altera.com, you need to add software.altera.com to your /etc/hosts

Also, since they're on akmai, you need to get a new ip.

Just check the ips on nslookup before adding them to /etc/hosts

you can avoid some of these headaches by grabbing the isos on software.altera.com
