Why tftp direct access request to different folders with different network interfaces

Here's my /etc/xinetd.d/tftp service tftp { socket_type = dgram protocol = udp wait = yes user = root server = /usr/sbin/in.tftpd server_args = -s /tftpboot disable = no per_source = 11 cps = 100 2 flags = IPv4 } I have two interfaces on my host: 1. lo: 127.0.0.1 2. virbr1: 192.168.122.1 And I connect the tftp server via the 2 interfaces respectively. tftp 127.0.0.1 get somefile The file is fetched from /tftpboot tftp 192.168.122.1 get somefile The file is fetched from /var/lib/tftp I have no idea where this /var/lib/tftp configuration comes from. Or maybe via 192.168.122.1, tftp servers fall back to some default configuration? --- Mention that I didn't modify /etc/xinetd.conf either: defaults { # The next two items are intended to be a quick access place to # temporarily enable or disable services. # # enabled = # disabled = # Define general logging characteristics. log_type = SYSLOG daemon info log_on_failure = HOST log_on_success = PID HOST DURATION EXIT # Define access restriction defaults # # no_access = # only_from = # max_load = 0 cps = 50 10 instances = 50 per_source = 10 # Address and networking defaults # # bind = # mdns = yes v6only = no # setup environmental attributes # # passenv = groups = yes umask = 002 # Generally, banners are not used.
