Troubleshooting
Problem
-25580 error connecting via Informix SDK ilogin or connect test demo or ODBC apply & test
Cause
- Configuration issue with the firewall on the Windows client, destination server, or on the local area network (LAN)
- Hostname resolution problem
- Service name resolution problem
Diagnosing The Problem
- If possible, temporarily disable firewalls involved to see if that allows the connection. Here are instructions for a Linux firewall:
The firewall on the Linux box is enabled by default. To disable the firewall on the Linux box issue the following command:
/etc/init.d/iptables stop
usage: /etc/init.d/iptables [start|stop|restart|condrestart|status|panic|save]
- Use the destination ip address in your connection information instead of the hostname to test if hostname resolution is the problem. ping the hostname from the client. ping the destination ip from the client
- Use the destination port number in your connection information instead of the server to test if service name resolution is the problem.
Resolving The Problem
- If disabling firewalls allowed the connection to complete, then you'll need to determine what changes are required on the firewall to have it enabled but allow the connection.
- Several reasons a hostname might not resolve but it might not be known on the DNS or a setting that controls where the computer first looks to resolve the hostname are not set correctly. Could be a hostname or ip address typo. There are certainly more causes.
- If a service name is not resolving it is most likely a typo but there could be other causes.
