Package: atftpd
Version: 0.7.git20120829-1
Severity: normal
Tags: lfs
Dear Maintainer,
Attempting to transfer a binary file with a length of 47462048 bytes causes
atftpd to send an ICMP port unreachable to the client.
The server is run out of inetd:
tftp-server$ head -1 /etc/default/atftpd
USE_INETD=true
tftp-server$ grep tftp /etc/inetd.conf
tftp dgram udp4 wait nobody /usr/sbin/tcpd
/usr/sbin/in.tftpd --tftpd-timeout 300 --retry-timeout 5 --maxthread 100
--verbose=5 /tftpboot
We have attempted to transfer a binary file from a Cisco router to atftpd
via a directly-connected network segment. A tcpdump on the segment monitoring
the transfer shows a port unreachable sent from the server (192.168.253.21):
