[CentOS] [CentOS 5] tftp-server, unable to create new files (even with "-c" option)

[Davide Grandis]

Hi Grant,

No luck again with the w/a you provided.

Here is the result of more investigation:

1) disabled (disable = yes) in /etc/xinetd.d/tftp

2) reboot or just "service xinetd restart"

3) run in.tftpd

Writing to a new file still fails. This is what I discovered from / 
var/log/messages:

Sep 13 23:56:39 chl1 xinetd[2301]: START: tftp pid=3036 from=10.58.2.159

That is, xinetd automatically starts TFTP when a TFTP request comes  
in. 10.58.2.159 in fact is the IP address of the switch from which  
I'm trying to TFTP-ing.

Checking the processes it turns out that:

[root at chl1 log]# ps -ef | grep tftp
root      3014  2813  0 23:55 pts/2    00:00:00 ./in.tftpd -c -v -u  
root -s /tftpboot
root      3036  2301  0 23:56 ?        00:00:00 in.tftpd -s /tftpboot
root      3043  2888  0 23:57 pts/3    00:00:00 grep tftp
[root at chl1 log]#

two tftpd are running. Apparently the one responding is the one w/o  
the '-c' option!!!

Can someone please explain to me why xinetd is starting tftp, even if  
disabled!?!?!?

Thanks,
Davide
