Fedora is not in the sudoers file
解决方案:

$su –
(注意有- ,这和su是不同的,在用命令”su”的时候只是切换到root,但没有把root的环境变量传过去,还是当前用户的环境变量,用”su -“命令将环境变量也一起带过去,就象和root登录一样) Continue reading Fedora is not in the sudoers file
samba start error
smbd: relocation error: /lib/libsamba-credentials.so.0: symbol GSS_KRB5_CRED_NO_CI_FLAGS_X, version gssapi_krb5_2_MIT not defined in file libgssapi_krb5.so.2 with link time reference
Package krb5-libs-1.13.2-11.fc23.i686 is already installed
should update krb5-libs-1.13.2 to krb5-libs-1.14.1
so: sudo dnf install krb5-libs-1.14.1-*
other words, security should be set as share
or smbd would not start properly (error exit)
