X forwarding: trying to forward to busy local port

[Jim Knoble]

Circa 2007-02-19 06:06 dixit Lars Kruse:

: Maybe I get something wrong, but for now the setting "AdressFamily any"
: seems to severely degrade the reliability of X-forwarding setups.
: Did someone already file a bug report for this behaviour? I could not
: find any. Otherwise I would like to do create one.

Anyone know if there's an IPv6 equivalent to Linux's
/proc/sys/net/ipv4/ip_local_port_range (equivalent to the
'net.ipv4.ip_local_port_range' sysctl)?  Under IPv4, this twiddles the
port range available when connect(2)-ing without specifying the local
endpoint's TCP port number.

If there is such a twiddle for IPv6, you might be able to use it to work
around this problem.  For example, with the IPv4 setting:

    su root -c sysctl -w 'net.ipv4.ip_local_port_range=7000 65535'

Best,
jim
