ISQL remote connection from Win to Linux - Server name not found

Hi,

I'm new to SYBASE. I've installed AES on RED Hat 6.0 and I can connect locally via ISQL.

Then I downloaded the SDK onto Windows 2012 Server, but cannot connect remotely.

SERVER: wrkredhat6.0x64

STATIC IP: 192.168.242.199

DATABASENAME: SYBASEDB

I run the following windows console command:

isql -Usa -Ppassword -SSYBASEDB -H192.168.242.199

But I get error: Requested server name not found.

Many thanks,
