    Hi folks,

    Ubuntu 8.04 Hardy - Host
    Ubuntu 8.04 Hardy - Guests

    Debian Etch - Host
    Debian Etch - Guests

    Both machines together with their guests are working. They can ping and ssh-connect each other on IP. But they can't ping nor ssh connect each and others (both local and remote machines) on hostname. I have been playing around on hosts, hostname, resolv.conf, mailname, etc. for 2 days without a solution. Please help. TIA

    Hi kcharoen,

    Solved the problem already by putting IPs and hostnames of all machines on /etc/hosts, both physical and virtual.

    $ grep hosts /etc/nsswitch.conf
    hosts:          files mdns4_minimal [NOTFOUND=return] dns mdns4
    "files" is at the beginning of that line. I did not make any change.

    I heard winbind can solve the problem avoiding having a long list on /etc/hosts. Its setup is simple. Of couse bind9 is another option but its setup is not easy. Another option is samba.
