How to force an application to use only ipv4?
Hi, I have a problem connection from thin clients (old machines) to server using xdmcp ( connection thru X using port 6000 and 6001), with previous debian 6.0.7, mint 13, I had problem, with recent distro mint 14 or 15 , debian 7, I have connection pb I suspect a conflit ??? between ipv6 and ipv6 ? may be my old machines don't understand this protocol ? I want to test mint15 with just ipv4, I want to force ipv4 on the mdm manager ( gnome-like) where to do it ?? here is the output for open port netstat -nau |grep 177 udp6 0 0 :::177 :::* netstat -nat |grep 6000 tcp0 0 0.0.0.0:60000.0.0.0:* LISTEN tcp6 0 0 :::6000 :::*LISTEN no port open on ipv4 udp ?? thanks for help

Does your old machine have an IPv6 address? Does your new machine have an IPv6 address? Can you ping6 one machine from the other? % ip -6 addr 1: lo: LOOPBACK,UP,LOWER_UP mtu 65536 inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: BROADCAST,MULTICAST,UP,LOWER_UP mtu 1500 qlen 1000 inet6 2001:770:1d5:::::/64 scope global dynamic valid_lft 86396sec preferred_lft 14396sec inet6 fe80::62a4:4cff:fe5f:1257/64 scope link valid_lft forever preferred_lft forever Note the global address for eth0. If you can't ping6 the other machine, then there's probably no IPv6 connectivity. All services should default to IPv6 and fall back to IPv4 if unavailable. Regards, Roger -- .''`.

Hello abdelkader Excerpt from abdelkader belahcene: -- snip -- I want to test mint15 with just ipv4, I want to force ipv4 on the mdm manager ( gnome-like) where to do it ?? -- snip -- I do not know mint but with debian wheezy it is easy to turn off/on IPv6 on the fly: /etc/sysctl.d/ipv6.conf # Disable IPv6 net.ipv6.conf.all.disable_ipv6=1 ---/ then you need to activate those settings with: # sysctl -p /etc/sysctl.d/*.conf -- Regards, Thilo 4096R/0xC70B1A8F 721B 1BA0 095C 1ABA 3FC6 7C18 89A4 A2A0 C70B 1A8F -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
