that was so simple... it solved my problem in a snap!!

now i have to figure out how i can assign my sun ultra to a separate VLAN on my cat2924 switch and make it a tftp server

do you have any support in this direction!

thanks

tftp should be installed by default.

You should find a line in your /etc/inet/inetd.conf that looks like:

#tftp   dgram   udp6    wait    root    /usr/sbin/in.tftpd      in.tftpd -s /tftpboot

I don't recall if it is commented by default or not. If so, uncomment and hup inetd.

Wrappers are recommended of course... --

Dude, you gotta buy a book or something.

ps -ef | grep inetd

    root   172     1  0 11:27:57 ?        0:00 /usr/sbin/inetd -s

172 is the pid.

kill -HUP 172

The inetd.conf file is a list of all the services to which inetd responds. Unless you specifically need the service, you can pretty much comment everything out.

Here is an example to quickly see which lines are NOT commented out:

(202)[aharriso@mail] [/export] # grep '^[^#]' /etc/inetd.conf
telnet  stream  tcp     nowait  root    /usr/local/sbin/tcpd    /usr/sbin/in.telnetd
(203)[aharriso@mail] [/export] #

As you can see, I comment everything except telnet, which I have wrapped and only allow from a local private network.

tcp wrappers can be obtained from sunfreeware.org and contain installation instructions within. After installation, you can simply use my example line above in your inetd.conf.

tcp wrappers rely on a couple of files, /etc/hosts.allow and /etc/hosts.deny. In the deny file, I just have:

ALL: ALL: DENY

In the allow file, I have lines like:

sshd,in.telnetd: 127.0.0.1 : ALLOW
sshd,in.telnetd: 192.168.0. : ALLOW
