I don't know either! :(

What is in /etc/krb5.conf ?


root at dc2:~# cat /etc/krb5.conf
[libdefaults]
    dns_lookup_realm = false
    dns_lookup_kdc = true
    default_realm = CAMPUS.SERTAO.IFRS.EDU.BR
root at dc2:~# ls -laht /etc/krb5.conf
-rw-r--r-- 1 root bind 115 Dec 12 15:31 /etc/krb5.conf

root at dc3:~# cat /etc/krb5.conf
[libdefaults]
    dns_lookup_realm = false
    dns_lookup_kdc = true
    default_realm = CAMPUS.SERTAO.IFRS.EDU.BR
root at dc3:~# ls -laht /etc/krb5.conf
-rw-r--r-- 1 root bind 115 Jul  7 11:33 /etc/krb5.conf

Is there any way I can increase the timeout in the command?
