tftp access violation error

[Mauro Gatti]

Hi all, I've a problem with tftp.
From a client I get this error...

virgo# tftp 172.16.200.14
tftp> verbose
Verbose mode on.
tftp> binary
mode set to octet
tftp> get prova
getting from 172.16.200.14:prova to prova [octet]
Error code 2: Access violation


On my tftp server I've this configuration:

leo# cat /etc/passwd |grep tftp
tftp:*:510:104:TFTP:/usat/tftpboot:/usr/bin/false

leo# cat /etc/group|grep 104
guest::104:tftp


leo# cat /etc/inetd.conf|grep tftp
# Before uncommenting the "tftp" entry below, please make sure
# that you have a "tftp" user in /etc/passwd. If you don't
# have one, please consult the tftpd(1M) manual entry for
tftp dgram udp wait root /usr/lbin/tftpd tftpd /usat/tftpboot

leo# ls -la /usat/tftpboot/prova; ls -lad /usat/tftpboot
-rw------- 1 tftp guest 5 Nov 4 15:18 /usat/tftpboot/prova
drwxr-xr-x 2 tftp guest 2048 Nov 4 15:18 /usat/tftpboot

I've tried also with:
leo# ls -la /usat/tftpboot/prova; ls -lad /usat/tftpboot
-rwxrwxrwx 1 tftp guest 5 Nov 4 15:18 /usat/tftpboot/prova
drwxr-xr-x 2 tftp guest 2048 Nov 4 15:18 /usat/tftpboot
and also with:
leo# ls -la /usat/tftpboot/prova; ls -lad /usat/tftpboot
-rwxrwxrwx 1 tftp guest 5 Nov 4 15:18 /usat/tftpboot/prova
drwxrwxrwx 2 tftp guest 2048 Nov 4 15:18 /usat/tftpboot


Could You help me?

Thank You

Error code 2 on unix means "No such file or directory".
Are you sure the file exists on your ftfp server?

Can you try putting a file up there and then getting it back ?

Mauro,
I think you need to give the full path of the file to tftp.

HTH,

What are the rights on /usat ?
And on the directory where you run the tftp client ? Could it be that there is already an prova file that is not writable ?

virgo# cd
virgo# pwd

virgo# echo "test" > pippo
virgo# tftp 172.16.200.14
tftp> verbose

tftp> put pippo
putting pippo to 172.16.200.14:pippo [netascii]
Error code 2: Access violation
tftp> put /pippo
putting pippo to 172.16.200.14:/pippo [netascii]
Error code 2: Access violation

Is prova a file or a directory ? If it's a directory, you can't download it this way, you need file names.
