exactly right, i think. i'll have to clean that cruft out of my existing systems. i just built a brand new VM, minimal install of squeeze, immediately upgraded to latest sid, reboot to get linux 3.0.0 kernel, then apt-get install munin-node. net.ipv6.bindv6only defaults to 0. munin-node works just fine on both ipv4 and ipv6 interfaces, after adding appropriate allow lines. root@ztest:/etc# sysctl net.ipv6.bindv6only net.ipv6.bindv6only = 0 root@ztest:/etc# telnet ::1 4949 Trying ::1... Connected to ::1. Escape character is '^]'. # munin node at ztest.taz.net.au list cpu df df_inode entropy exim_mailqueue exim_mailstats forks fw_packets http_loadtime if_err_eth0 if_eth0 interrupts iostat iostat_ios irqstats load memory nfs4_client nfs_client nfsd nfsd4 open_files open_inodes proc_pri processes swap threads uptime users vmstat quit Connection closed by foreign host. root@ztest:/etc# telnet localhost 4949 Trying 127.0.0.1...
