Re: Connection string

Hi Micheal,
sudde2nly a problem has cropped up in my connection.
Its kind of strange.

ECPGdegug(1, stderr) says

[9852]: connect: cold not open database dbxyz on 192.168.0.123 port 5432 for user jsb in line 16
     could not connect to server: No route to host
     Is the server running on host " 192.168.0.110" and accepting
     TCP/IP connections on port 5432?

My server is very much running.
I also made sure that TCP/IP connection is being accepted on port 5432 using nmap -sS localhost in my database server.

Don't know  whats wrong now

Also, just an observation (don't know if that is the cause or not) In my clinet machine while compiling my test.c file using
gcc -o test test.c -lecpg -L/usr/lib/pgsql
there's not pgsql directory in /usr/lib.
Where exactly do i have to do this linking thing and to what I have to link it.

Thanks

You might want to add 192.168.0.0/24 on another line rather than
replacing 127.0.0.1.  And allowing "trust" connections is bad
security practice because anybody on one of the allowed IP addresses
could connect as any user without being challenged for a password.
Consider using a stronger authentication method and modifying the
client code accordingly.
