你好，我目前正在运行 cobbler 和 dhcp，在重新启动 ubuntu 之前，一切都正常，现在我重新启动了主服务，但在 m syslog 中出现了这个错误
/var/syslog ....
bind failed (Address already in use (errno = 98))
. service = tftp
xinetd -d
17/5/21@17:42:25: ERROR: 3249 {activate_normal} bind failed (Permission denied (err
no = 13)). service = tftp
17/5/21@17:42:25: ERROR: 3249 {cnf_start_services} Service tftp failed to start and
is deactivated.
17/5/21@17:42:25: DEBUG: 3249 {cnf_start_services} mask_max = 0, services_started =
0
请你告诉我如何清除地址
谢谢
