Description of problem:
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. My home network works with a (legacy) Speedtouch Home/professional router with built in DNS. No ipv6 support. The DNS looks up local machine and then forwards to an external DNS of my ISP.
2. Fresh install of Fedora 15. Disable ipv6 (/etc/modprobe.d/dist.conf; Firefox/Thunderbird about:config network.dns.disableIPv6 true; /etc/sysconfig/network-scripts; chkconfig ip6tables off)
3.When using de internal (ipv4) DNS all seems to work (Firefox, Thunderbird, ping, nslookup, ...) except yum/wget/curl. Using a mirror address with wget en explicitly giving the "-4" option works however (which lead me to believe it's a ipv6 DNS problem).
Switching to an external (ipv6) DNS (such as 220.127.116.11) works for all packages, but obviously prevent lookup of local machines.
curl#6 - "Couldn't resolve host"
update of yum packages
Found related bugs 548269 and 548396, but seems to be different because I want my internal network on ipv4 (due to legacy).
Hi, thanks for the report! Yum does not support -4 and -6 in yum.conf.
However, you could manually change the urlgrabber's defaults.
- self.ip_resolve = None
+ self.ip_resolve = 'ipv4'
But there's something wrong in your setup, as curl should not exit with ERR#6, but fall back IPv4 "A" records. Could you run
# export URLGRABBER_DEBUG=1,debug.txt
# yum update
and attach the debug file?

Thank you very much for your quick reply. The trick in /usr/lib/python2.7/site-packages/urlgrabber/grabber.py does indeed solve the initial problem. I have no idea why curl exits with ERR#6. If it is of any help, I could attach the new debug file ?
The upstream yum now supports 'ip_resolve' option in yum.conf, so just set 'ip_resolve = ipv4' there. Fixed in upstream, closing.
