HI, We made some changes recently(2.7?) to use the os shipped tftp server instead of the xCAT one. For configuring the os shipped tftp server, AAsn.pm intentionally configured disabled=yes into /etc/xinetd.d/tftp, and start tftp directly by calling "/usr/sbin/in.tftpd $v4only -v -l -s /tftpboot -m /etc/tftpmapfile4xcat.conf", because we noticed that starting tftp through xinetd did not work well in some scenarios, for example, the system has alias ip addresses configured.
Thanks,

Mailing list compatibility issue?
<xcat-user@lists.

Saw a similar report in the bug tracker, so there’s a chance there’s a fix
being worked on:
http://sourceforge.net/tracker/index.php?func=detail&aid=3505360&group_id=208749&atid=1006945
However after updating to the latest snapshot, the xinetd.d/tftp file is
still being overwritten by AAsn.pm. The version are now:
[root@drdkvm0003 /]# rpm -qa | egrep -i 'atftp|xcat-server'
atftp-server-0.7-6.el6.rf.x86_64
xCAT-server-2.7.3-snap201206110241.noarch
Perhaps the easiest short term fix for me is just to allow AAsn.pm to
generate a non-working xinetd conf file for tftpd, and to start tftp from a
separate, /etc/init.d/tftp init script. I’m a little hesitant to do this
because there’s code in AAsn.pm that restarts xinetd, which would result in
tftp being restarted, and if an init script is used to start tftp instead,
xcat will not have control over tftp.
Thanks,
Goran

Subject: xcat - tftp compatibility issue?
I have the following installed on a Linux CentOS 6.2 Management node:
xCAT-server-2.7.1-snap201204060047.noarch
atftp-server-0.7-6.el6.rf.x86_64
Once installed, whenever xcatd is restarted, the following xinetd file is
generated for tftp:
[root@drdkvm0003 xcat]# cat /etc/xinetd.d/tftp
# default: on
# description: The tftp server serves files using the trivial file transfer
protocol. The tftp protocol is often used to boot diskless worksta.
service tftp
{
disable = yes
socket_type = dgram
protocol = udp
wait = yes
user = apache
group = apache
server = /usr/sbin/in.tftpd
server_args = -s /tftpboot -m /etc/tftpmapfile4xcat.conf
per_source = 11
cps = 100 2
flags = IPv4
}
However according to the atftpd man page, the server args above won’t work.
in order to work with atftp, the following changes are needed:
[root@drdkvm0003 xinetd.d]# diff /tmp/tftp /etc/xinetd.d/tftp
5c5
< disable = yes
---
> disable = no
12c12
< server_args = -s /tftpboot -m /etc/tftpmapfile4xcat.conf
---
> server_args = -v --logfile /var/log/tftpd /tftpboot
The problem is every time xcatd is restarted, /etc/xinetd.d/tftp is
overwritten by: /opt/xcat/lib/perl/xCAT_plugin/AAsn.pm
I wondering whether I should look for a different version of tftpd, try
the latest xCAT snapshot, or look for a configuration problem? Likely the
default of “disable = yes” is a configuration issue in my db, but the
AAsn.pm doesn’t appear to have much wiggle room for different tftpd
server_args.
(BTW I tried installing atftp-xcat, but it shows that it’s been obsoleted
by xCAT-server.)
Thanks,
Goran
