Hi,
from man yum.conf:
ip_resolve Determines how yum resolves host names.
`4' or `IPv4': resolve to IPv4 addresses only.
`6' or `IPv6': resolve to IPv6 addresses only.

Added:
"OPTIONS=-4 -named" to /etc/sysconfig/named,
disabled ipv6 per interface,
created /etc/modprobe.d/ipv6_disable.conf file with
alias net-pf-10 off
alias ipv6 off
options ipv6 disable=1
but still getting the same error message.
Maybe it just needs a reboot (which im trying to avoid)

You must stop using the module then you can unload it. Busy usually means you have IPv6 addresses on some interfaces -- ip -6 addr flush dev ethX. /mark
Our network admin blocked ports (don't know why - i asked him 2 weeks before I started to troubleshoot the system). Everything is fine now, thanks for help. -----Original Message----- From: Mark Milhollan [mailto:mlm at pixelgate.net] Sent: Monday, December 29, 2014 9:21 PM To: Mateusz Guz Subject: RE: [CentOS] (py)curl error 7 On Mon, 29 Dec 2014, Mateusz Guz wrote:>Ip -6 a shows no output > >after "visual" inspection i don't see any ipv6 addresses assigned to my eth interfaces > >On Mon, 29 Dec 2014, Mateusz Guz wrote: >>On Sun, 28 Dec 2014, Mark Milhollan wrote: >>>On Fri, 26 Dec 2014, Mateusz Guz wrote: > >>>>created /etc/modprobe.d/ipv6_disable.conf file with >>>>alias net-pf-10 off >>>>alias ipv6 off >>>>options ipv6 disable=1 >>> >>>These only take effect if you reboot or unload the modules manually. >> >>Tryning not to reboot, when unloading I get the message that the modules is in use. >>I think that forcing the unload is too dangerouse, read that it might resolve in kernel panic. > >Forcing an unload wouldn't be wise.
