TFTP service refusing connections

Question

I've installed atftpd, and configured it as follows:

boban@netmonitor:~$ cat /etc/default/atftpd
USE_INETD=false
OPTIONS="--tftpd-timeout 300 --retry-timeout 5 --mcast-port 1758 --mcast-addr 239.239.239.0-255 --mcast-ttl 1 --maxthread 100 --verbose=9  /tftp/"

boban@netmonitor:~$ ls -ld /tftp/
drwxrwxrwx 2 nobody root 4096 2012-01-16 13:06 /tftp/


boban@netmonitor:~$ ls -l /tftp/test.txt 
-rw-rw-rw- 1 nobody root 12 2012-01-16 13:06 /tftp/test.txt

boban@netmonitor:~$ cat /etc/hosts.allow
in.tftpd: LOCAL, 192.168.150.66
atftpd: LOCAL, 192.168.150.66

boban@netmonitor:~$ tftp localhost
tftp> get test.txt
Received 12 bytes in 0.0 seconds

But, from other host, I'm getting:

boban@boban:~$ tftp 192.168.150.85
tftp> get test.txt
Transfer timed out.

Logs on tftp server shows:

Jan 16 15:20:40 netmonitor atftpd[13503]: Creating new socket: 192.168.150.85:37057

Jan 16 15:20:40 netmonitor atftpd[13503]: Aborting transfer
Jan 16 15:20:40 netmonitor atftpd[13503]: Server thread exiting

There is no iptables filtering on both sides. Is there a way to solve this?
