 Posted: Sun Dec 11, 2011 5:29 pm Post subject: dibbler-client segfaults |
 |
|
Hello all,
I've been trying to setup ipv6 since my ISP has launched a ipv6 beta programme. I've been following various guides online, and dibbler seemed to work the first time I ran it. However, for some reason it keeps segfaulting now. I tried upgrading to the latest version from git, which gives me a little more output on the console, but it also results in a segmentation fault. Here's the output:

Here's my /etc/dibbler/client.conf:
| Quote: | #
# Example client configuration file: default
#
# Uncomment following line to use Link-layer DUID instead of default Link-layer+time
#duid-type duid-ll
# Uncomment following line to make dibbler very aggressive about getting requested
# options.
#insist-mode
# Uncomment following line to make dibbler accept downed/not associated interfaces
inactive-mode
# Uncomment following line to make confirm enable at start
#use-confirm
# Uncomment following line to skip confirm sending (after crash or power outage)
# skip-confirm
log-mode short
# 7 = omit debug messages
log-level 7
# Current Dibbler release adds obtained addresses with /64 prefix. Although
# this violates spec (RFC3315), it is very useful as hosts in the network can
# exchange data immediately. To restore previous behavior, uncomment this line:
# strict-rfc-no-routing
# Dibbler can detect interfaces and ask for address on every suitable interface.
# If that is what you require, just don't mention any interfaces
# On the other hand, you may want to specify interfaces to be configured
# explicitely
#iface "eth1" {
# ia
# option dns-server
# option domain
#}
iface ppp0 {
rapid-commit yes
pd
option dns-server
}
