microsoft.public.dotnet.framework.remoting

Client without config file

Hello,
I have created an remoting application which worked quite well until I
realized that I needed to secure my network transmission someway. To
do this I created a custom sink which encryts and decrypts the message
for transmission. I have used a config file for the server portion but
I would like to stay away from a config file on the client end.
Currently here is the code which is in my server config file:

<configuration>
<system.runtime.remoting>
<application>
<channels>
<channel ref="http" port="1235">
<serverProviders>
<provider
type="CustomSinks.CustomServerSinkProvider, CustomSinks"
customSinkType="LameEncryption.LameEncryptionServerSink,
SampleSinks" />
<formatter ref="soap" />
</serverProviders>
</channel>
</channels>
</application>
</system.runtime.remoting>
</configuration>

As you can see it calls the custom sink of
Lameencryption.lameencryptionserversink, sample sinks to do the
encryption. Now on my client I currently have this code to start the
remoting:

httpportval = 1234
HttpString = "http://" & httpName & ":" & Httpportval &
"/4micros.soap"

Dim mgr As IMicrosManager =
CType(Activator.GetObject(GetType(IMicrosManager), HttpString),
IMicrosManager)


So I would assume that I need to change something here in the client
which would tell the program how to use the custom sink. I have the
book "Advanced .NET Remoting in VB .NET" if you want to refer to a
page number, otherwise, I would love some assistance. Thanks!

Ingo Rammer''s (excellent) book has a good section on this which should help
you. Just out of interest, did you consider using SSL via IIS?

I will not have IIS on the machines running this program so I cannot go
that route and I would like to avoid using a config file so that no
person can change the config file to get around the security. Any other
ideas? Thanks!

Hi,

a little out of topic, but it seems that with the current framework
there are some problems with using config files. Maybe you should
consider using programmatic configuration.

Take a look at this article:

Thanks for the help, It close but not exaclty. In your example it shows
how to use an interface to create the client object which is what I have
done. Now I just need to programmincly state how the custom sink chain
should work and be used. I have it working in a config file for the
server but I would like the client side to be hard coded. Thanks again
for the help, any other ideas?

Kevin
