Network Problem IDS7.30.UC3+Linux (SuSE6.1)

When I try to start the Dynamic-Server, setup with the following: IDS 7.30.UC3 Linux SuSE 6.1-i386 (Kernel 2.2.9, libc6). sqlhosts: ifxdms onsoctcp lxsrv ids_tcp /etc/services: ids_tcp 1526/tcp I get the following error-messages in the online-logfile: listener-thread: err = -25580: oserr = 0: errstr = : System error occurred in network function. listener-thread: err = -25573: oserr = 11: errstr = : Network driver cannot accept a connection on the port. System error = 11. (repeated every few seconds....) dbaccess doesn't work (Message: Network down) I tried different ports, but with no change in this behaviour. ----- If I change the sqlhosts-file to access via shared-memory like: ifxdms onipcshm lxsrv ifxdms the server seems to run fine. I also can connect local via E/SQL (9.16.UC3), that I use to access the Database from our Intranet-Webserver (Apache+PHP3). ----- Does anybody know something about network-problems with IDS and Linux and if there is a workaround ? I need to connect to the IDS over TCP/IP from other clients in the network. I hope that somebody could help me. Thanks in advance Martin Gutjahr
