Dear Miguel,
Package: x2gobroker Version: 0.0.3.1
When x2gobroker-ssh is used with system with not IPv6 configured,
this generate very big delays in x2gobroker listsession task.Before some research, the problem become from x2gobroker.utils
portscan function.This function propagates a delay in all agents call because it tests
first the IPV6 connection:/ip_proto = 0////try:////socket.getaddrinfo(addr, None,
socket.AF_INET6)////ip_proto = 6////except
socket.gaierror:////try:////socket.getaddrinfo(addr, None,
socket.AF_INET)////ip_proto = 4////except socket.gaierror:////# we
can't find a valid address for this host, so returning a
failure...////return False /This will be fixed testing IPv4 first or
more easily, setting a new option in config to select the ip protocol.
A while ago you reported the above issue.
I tested this now.
The portscan function in x2gobroker.utils is really fast when
detecting that a remote host is not IPv6 supportive. It basically is a
fast DNS query.
Is it so, that your client system has IPv4 disabled entirely (in the
kernel)? Or what exactly did you mean by "When x2gobroker-ssh is used
with system with not IPv6 configured..."?
I am willing to do more test, please provide more info. You possibly
also have found a fix meanwhile. If so, I'd be happy, if you could
share it.
Thanks Mike
