ThinClient & TFTP Server remap - feature needed

(1/1)

In order to boot WinPE with PXE a remaping is necessary

Unfortunately the smeserver-tftp-server has no remaping entry.

--- Quote ---~]# config show tftpd
tftpd=service
UDPPort=69
access=private
directory=/tftpboot
log=normal
privilege=r
status=disabled
timeout=normal
user=root

--- End quote ---

As a workaround I add a reference in the db.

--- Quote ---~]# config setprop tftpd remap /tftpboot/tftpd.remap
~]# config show tftpd
tftpd=service
UDPPort=69
access=private
directory=/tftpboot
log=normal
privilege=r
remap=/tftpboot/tftpd.remap
status=disabled
timeout=normal
user=root

--- End quote ---

This is not the cleanest method, but I edit the file /service/tftpd/run

--- Quote ---~]# nano /service/tftpd/run

#!/bin/bash

#db configuration show tftpd
#Database: configuration
#Key: tftpd
#PROP: status VALUES: enabled/disabled
#PROP: access VALUES: private/public/localhost
#PROP: log VALUES: normal/verbose/disabled
#PROP: user VALUES: root/nobody (or any other valid user)
#PROP: privelege VALUES: ro/rw
#PROP: timeout: VALUES: default/300 (secounds, 900 is the default)
#PROP: UDPPort: VALUES: 69
#PROP: directory VALUES: /tftpboot (or any other directory)

TFTPD_STATUS=$(/sbin/e-smith/db configuration getprop tftpd status);
if [ $TFTPD_STATUS == "enabled" ]; then

elif [ $TFTPD_ACCESS == "private" ]; then
TFTPD_ACCESS_SETTING=$(/sbin/e-smith/db configuration get LocalIP);

fi

if [ $TFTPD_PRIVILEGE == "rw" ]; then

fi

if [ $TFTPD_TIMEOUT != "default" ]; then
TFTPD_TIMEOUT_SETTING="-t $TFTPD_TIMEOUT";
fi

Now you must restart tftpd

--- Quote ---~]# /etc/init.d/supervise/tftpd restart

--- End quote ---

The problem is that this change does not support the upgrade.

If anyone has a solution to make this a permanent feature. Or maybe add it in the new feature of smeserver-tftp-server

Hi,

please add it to the bug tracker here and you may find it gets implemented, or you could supply a patch yourself that might get included. The more you do, the more likely it will happen !!!! :-)

Go here and add your bug under sme-tftp-server

http://bugs.contribs.org/enter_bug.cgi?product=SME%20Contribs

I think the rpm needs the following :

new db default :
/etc/e-smith/db/configuration/defaults/tftpd/remap

containing :
/tftpboot/tftpd.remap

Your mod gives a diff something like this :

HOWEVER, it MAY need to check for the presence of the remap as a db entry (I am not sure what happens if there is no entry and guess it would fail so you might need something like this) :

Note that my coding skills are extremely limited so the above needs comprehensively checking and testing !!!!! I am sure that the package maintainer will help you on the bug tracker.
