OK, summary time:
We are running Mandrake 6.1 as our internet gateway on a Pentium II with
64Mb RAM. According to the FAQ etc, with my kernel I should be using
ipchains, but was trying to cover all bases.
The Board of Studies now requires that we upload student data directly to
their website and the data is formatted by an Access database that we
download. The database attempts to connect to their site on port 4545. The=
y
have advised that the error I am getting indicates that I have a firewall =
with
port 4545 blocked and that I need to open it for output.
I knew nothing of ipchains and so am on a learning curve.
Ipchains -L tells me that there are no 'rules' and all policies are set to=
ACCEPT, hence to my confused mind no firewall.
I can access their system by dialling through my own account (same ISP)
so wil give up on this I think, until I have more carefully thought and re=
ad all
this info.
Thanks for the help everyone, at least I now know more about this system.
