I need to use socks proxy in Firefox on my laptop
, using ssh tunnel to server
On my laptop
, I set socks proxy in firefox, and connect to server
:
ssh server -D1234
When I visit any website in firefox, the proxy works, but I get these errors:
on laptop
(in the console where I started ssh)
channel 15: open failed: connect failed: Address family for hostname not supported
on server
(in syslog):
sshd: error: connect_to ff00::: unknown host (Address family for hostname not supported)
this looks like firefox is trying to use IPv6
. But I have no IPv6
support either on laptop
or on server
. And I have explicitly disabled IPv6
in firefox, by setting network.dns.disableIPv6
to true
.
As said, everything works. But I am just bothered by the flood of error messages.
How can I prevent Firefox from even attempting to use IPv6
, or if that is not possible, to get rid of the error messages on both laptop
and server
.
The laptop
is running Debian 12, and server
is running Debian 10.
Both have custom linux kernel, without IPv6
support.
