Common tftpd Problems
This section discusses the common tftpd problems and possible resolutions.
Symptom:
A file transfer ‘timed out’ message is displayed. inetd connection logging (enabled with the
inetd -l command) does not show any connection to the TFTP server.
Cause:
The TFTP server, tftpd, did not start.
Action:
□ Ensure that the /etc/inetd.conf file contains the appropriate tftp entry.
□ Ensure you have reconfigured inetd with the command inetd -c.
□ Ensure that the bootpd server is configured properly for tftp to transfer the boot file. For
information on configuring bootpd, see “Configuring the BOOTP Server” (page 101). Now,
try to transfer a file on a different node on the network, instead of the server node.
If the server still fails to start when the client attempts the file transfer, it may be a connectivity
problem. See Installing and Administering LAN/9000 Software or the BOOTP client manual
(for example HP 700/X documentation).
Symptom:
File transfer timed out. The system log contains one of the following messages:
User tftp unknown
system_call: error
Cause:
The TFTP server, tftpd, exited prematurely.
Action:
TFTP may exit due to the following problems:
□ Problem in the network: You can increase the per-packet retransmission and the total
retransmission timeouts using the tftpd timeout options -R or -T. For more information,
type man 1M tftpd at the HP-UX prompt.
□ System call failure: tftpd can exit if a system call failure occurs. The name of the system
call and cause for the system call failure are logged in the system log file
/var/adm/syslog/syslog.log. For more information about the cause for failure, see
the system call in the HP-UX Reference at the URL
http://www.docs.hp.com/hpux/os/man_pages.html.
□ Problem with the password database entry: The error message User tftp unknown can
occur if the password database entry for the user tftp is either missing or incorrect. Verify
if the entry exists and is correct, and transfer the file again.
Symptom:
File transfer fails with File Not Found, No Such File or Directory, or TFTP Error
Code 1 message.
Cause:
The file that the client is attempting to read from or write to the server does not exist within the
home directory of the user tftp or in the path specified with the tftpd command.
