Subject interclient, jdbc and linux subsystem
Author tengicki@sdctec.net
Hello,

I have some problem with interclient 1.6 and interbase 6.0 under
Linux (FreeBSD).

Our provider has organized the server in subsystems. Thats means
that there are logical system with own ip-adresses and access
rights on one physical system.

for example the server has the ip 1.2.3.1 (and can be called as
localhost (127.0.0.1)

an apache with jserv is runnung unser ip 1.2.3.2 on the same
server and make a connect to interclient
jdbc:interbase://localhost//usr/databases/db.gdb thats work fine

now we have running a second apache with jserv under ip 1.2.3.3
on this
server. apache and jserv work well

But if I try to connect the database from the second jserv
environment the
java statement


java.sql.DriverManager.getConnection (databaseURL, user, password)


didn't come back. No exception, or something like else.


Because of the fact that all subsystem has the same physical server localhost
"pointed" to the same machine. If there is any call identification via localhost
it must fail. What uses interclient to connect to interbase, what uses jdbc as
local ip where the call come from. How can interclient make differences
between the calls from subsystem on (1.2.3.2) and subsystem (1.2.3.3) if
they have the same localhost (127.0.0.1).


Have anyone any idea, about what happens, what is to do, where I can find
more information. Thank you.
