Bad File Permission

[Richard <nospam [at] zetnet.co.uk>]

Hello

Here's a good one :-)

I've set up a user in /home/user so that I don't use root to connect
to the internet. After further tests last Monday night I had a
denial of service attack performed on me whilst downloading Grass
4.21 from www.baylor.edu. This was a bit of a pain just before demo
day but I managed to get round it by re-installing the system.

I've started X as the user and I'm getting the following when I try
to start Kisdn to connect to the internet.....

Bad file permission

I can't set the correct permission of the config file
/home/user/kde/share/config/kisdnrc
It should be readable, only writable by the owner,
because the passwords for your ISPs are stored there

So what do I do ? I've read the Howto and all of the books at
Blackwell's. Nothing doing there :-( What do I change to get Kisdn
to work ?

On a different but related theme I've been able to enable the
firewall with ipchains -P input DENY. This works fine but doesn't
allow me to view web pages or send and receive e-mail. And what
about ftp ?? What's the correct syntax to allow my web browser to
work ? I have to connect to port 3128 at my ISP. E-mail download is
on port 110 and send is on port 25.

So... do I put something like ipchains -P input DENY allow 3128 110
25 ???

Thanks
