Configuring TFTP and BOOTP Servers
Troubleshooting BOOTP and TFTP Servers
Symptom: File transfer fails with Access Violation, Permission Denied, or
TFTP Error Code 2 message.
Cause: tftpd does not have permission to read the file.
Action: If the transfer is a get operation where the client is attempting to read
the file from the server, then the server does not have read permissions
on the file that it is trying to send. Ensure that the file the client is
reading has read permissions for the user tftp. For example, if the
client was attempting to read the file named xterm, xterm should be
mode 0400 and owned by the user tftp:
$ ll /home/tftpdir/xterm
-r-------- 1 tftp guest 438 May 10 1989 xterm
If the transfer is a put operation (which is not something a BOOTP
client will be doing as part of the BOOTP protocol), then this message
means that the file did not have sufficient write permissions for the
server to write to the file. If the server is to receive a file, it must already
exist and be writeable by the user tftp. For example, if a tftp client is
sending the file named fontlist, the file must be mode 0600 and owned
by tftp:
$ ll /home/tftpdir/fonts
-rw------- 1 tftp guest 0 May 10 1989 fonts
Error Logging
This section explains the error messages that bootpd logs through
syslogd. The three levels of error logging documented in this section
are as follows:
• “Information Log Level” on page 191
• “Notice Log Level” on page 193
• “Error Log Level” on page 193
The bootpd debug level must be set for these messages to be logged. Set
the debug level using the -d option to bootpd.
Information Log Level
The following messages are logged at the syslogd information log level.
