SSh on Solaris 9 + how to overcome spamming issue (dnsbl)? 1

[withu]

Dear All,

I am using Solaris 9 with the sendmail version of 8.12.2.
I'd like to install and configure ssh on a my machine and then disable telnet.Can anyone just guide me in this regards and where to retrieve ssh?


Added to that, email account in my mailserver is getting mails from those users which r not at all existing and may be those mails are spam so can anyone help me out in getting rid of this Spam mails. I heared of dnsbl configuration but didn't get the exact steps about the configuration of that...

Hope to hear from u soon.

Thanks in advance..
With best regards...
WITHU

You can get ssh from

http://www.openssh.org.

You will need to have openssl installed. You can get openssl from

http://www.openssl.org.

After you get both of those installed check to make sure you can ssh into your box. Putty is a free ssh client you can get it from

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html.

Make sure you add a start script for ssh or add it to initd which ever meets your needs. You then need to comment out the line for telnetd in your /etc/inetd.conf file and restart.

As for the spam issue try spam assassin it works with sendmail I believe and is found at

Hope this helps

do you not have ssh on your solaris 9?

the sparc version definately comes with it.

the anti-spam features of sendmail are good, but it's probably worth talking to the sendmail forum about it. forum14

or looking at

http://www.sendmail.org/antispam.html

following the links for the m4 section ... they also have links to 'milter' which is a 'mail filter' ...

is your sendmail talking on the internet ... or do you use fetchmail? the dnsbl thing only works if the blackhole'd machines connect directly to your machines sendmail, you're probably better off with '/etc/mail/access.db' feature turned on anyway if that is the case. the feature also only works if you're connected to a dnsbl that allows you to use it, the default one only works for paying customers.

if you use fetchmail, then you probably want to look at other mail filtering software on top of sendmail ...
