tftpd errors in syslog.log

Hi All,

I have found this error messagges in syslog.log:

tftpd: No control message received.
tftpd: Timeout (no response in 10 minutes)

I understand that is refer to tftp session from an external system to my server, that try to transfer file on my system, and this operation fails. But I don't understand "control message" what is and how I ca solve this problem.

thank you for you help! ;)

Shalom,

a tfptd session is being initiated, but not responded to. This could be a password prompt to the end user.

Check ownership of the home directory of tfptd as defined in inetd.conf The daemon is very sensitive to the tftpd user not owning the directory.

Re: tftpd errors in syslog.log

Thank Shalom,

I have check tftp home user and the owner is not "tftp" user but another user. The permission of the directory are 777.
In inetd.conf the home of tftp user does not appears but only /var/opt/ignite and /opt/ignite:

tftp dgram udp wait root /usr/lbin/tftpd tftp -s
/opt/ignite\
/var/opt/ignite

The strange thing is that this error does not appears always in the syslog and the tftp sessions go well many time.
If tftp configuration is uncorrect, why tftp sessions failed only sometime?

THK!

Re: tftpd errors in syslog.log

Shalom,

Best practices say tftpd needs to be the owner of the directory specified for tftpd file transfer.

I would fix that and see if the problem continues.

I don't think having permissions 777 is a good idea either, but don't in my head know best practices for this folder.
