Hello everybody,
I'm getting a strange trouble with TFTPd's Debian Etch, where it stops
without apparent reason.
I have to use the TFTPd for a Cable Modems network take it own CM file
to get online.
I installed the TFTPd by the usual way, "apt-get install tftpd". I
changed the conf of inetd, to serve tfp's files on /tftpboot.
Here following the inetd's and TFTPd's configuration:
###Configuration file
ns-mns:/var/log# cat /etc/inetd.conf
#:BOOT: TFTP service is provided primarily for booting. Most sites
# run this only on machines acting as "boot servers."
tftp dgram udp wait nobody /usr/sbin/tcpd
/usr/sbin/in.tftpd /tftpboot
###Permissions
ns-mns:/var/log# ls -la
drwxrwxrwx 2 root root 4096 2007-11-24 21:23 tftpboot
ns-mns:/tftpboot# ls -la
-rwxrwxrwx 1 nobody suporte 4203 2007-06-05 10:17 UP0300K

-rwxrwxrwx 1 nobody suporte 4203 2007-06-05 10:20 UP1300K
ns-mns:/var/log# cat /etc/hosts.allow
in.tftpd : ALL
###LOGS
ns-mns:/var/log# grep tftp daemon.log
### Few moments before the stop

### After a killall inetd

Nov 27 13:54:41 ns-mns tftpd[12610]: tftpd: serving file from /tftpboot
###I noted a strange behavior of tftpd while I was watching the opened doors
(pay attention to the value of Recv-Q):
ns-mns:/var/log# netstat -ntlpu
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
PID/Program name
udp 109344 0 0.0.0.0:69 0.0.0.0:*
12604/inetd
Ps.: the normal value of Recv-Q is zero "0".
###Watching the netstat man
ns-mns:/var/log#man netstat
Recv-Q
The count of bytes not copied by the user program connected to this
socket.
### Desperate attempt to stop the instability - Reinstalling the service
ns-mns:/var/log# grep tftp * | grep -v daemon.log | grep -v syslog
