Re: Connecting (IConnect) Solaris machine to a Linux server

Ciao, explanation by example: scenario: machine A (Solaris), IDS server name A1 machine B (Linux), IDS server name B1 Configuration machine A: onconfig file: ... SERVERNAME A1 ... sqlhosts file: A1 ontlitcp A portA B1 ontlitcp B portB /etc/services file: ... portA 87341/tcp portB 87342/tcp ~informix/.rhosts file (.rhosts file of user informix): ... B informix # short host name B.domain... informix # long hostname Configuration machine B: onconfig file: ... SERVERNAME B1 ... sqlhosts file: A1 onsoctcp A portA B1 onsoctcp B portB /etc/services file: ... portA 87341/tcp portB 87342/tcp ~informix/.rhosts file (.rhosts file of user informix): ... A informix # short host name A.domain... informix # long hostname With this you should be able to connect from IDS server A1 on machine A to IDS server B1 on machine B and vice versa. Note: - no changes are needed to the environments (environment variable seetings) on the machines. - rlogin is not used by IDS itself. But it can be used to test connectivity between machines, i.e. that login without password is working. - remote login without password for user informix is achieved by the entries in respective .rhosts files. - this remote connectivity without password (trusted user) is necessary for IDS remote queries to work. - for other users to be able to do remote queries I think you also have to do these entries. Alternatively you can use the mechanism of /etc/hosts.equiv (trusted hosts) for whole machines. - port numbers in /etc/services have to match. They are like telephone numbers ... - port numbers in /etc/services need to be unique, above I just picked arbitrary examples.
