on 20_05 we updatedto 2.1
in 22 we begun adding datacenter switches to DVC with public snmp community
afterwards we noticed vlan fetching inventory status failed
further investigation :
on the same day application logging reports:
05/22/14 10:39:26.380 INFO [admin] [Thread-3] TFTP logs:Unexpected Error in TFTP Server - Server shut down! + org.apache.commons.net.tftp.
now ncs status reports:
Ftp Server is running
Database server is running
Tftp Server is Failure
Matlab Server is running
NMS Server is running.
Plug and Play Gateway is running.
SAM Daemon is running ...
DA Daemon is running ...
Syslog Daemon is running ..
iptables are ok:
47 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:69
and no process using port 69 is found nor named tftp via netstat grep tftp
what is happening? (now I know the crash has been triggered by a security auditing... -.-)
is there a way to restart tftp only rather than the whole ncs ? (maybe via ADE root?)
thank you

Hi ,
Go to Administration > System Settings > Server Settings
check if TFTP service is enabled ? if not enabled it .
(restart ncs)

of course it is enabled
at this time I cannot restart whole ncs,
I was just wandering if was possible to fix tftp failure by restarting only TFTP

can you try
service tftpd start /restart
Thanks-

Unfortunately it looks like no tftp daemon rpm is installed on the system so service restart is not available for tftp in such way
as the error is reporting org.apache.commons.net.tftp.TFTPPacketException it looks like tftp is a service integrated into apache as a module
I'm starting to think full ncs stop and start as the only option...

Yes, you can do that , it will take around 5 mins only
if it is in production ,you can ask for MW.
