Re: Informix On-Line error: "not trusted by server"

Hi Yudong, In reply to Yudong Sun's email about Informix On-Line error: "not truste, on 16 Aug 96 > Whatever I do, I get the following error: > > 00:44:43 listener-thread: err = -956: Client host or user> (informix@torserv2.econnect.ca) is not trusted by the server. > Apologies in advance for the length of this reply. This error message is usually due to the missing hostname in /etc/hosts.equiv or $HOME/.rhosts file or non existence of these files. These files are used by the "r" commands (rlogin, rcp etc.) to establish user equivalence.I do not know the procedure if you are using DNS on the servers. But if you are using /etc/hosts as the means of recognising the servers on network, then anyone of the following should work. a) Create a /etc/hosts.equiv on the server, on which you want to do backup, with entry of the informix host. This will have systemwide effect of setting user equivalence. b) Create $HOME/.rhosts only for the user e.g. informix. E.g. If infserver1 is the Informix server whose data you want to backup and server1 is the server where actual backup would be run, then on server1. if using option a) /etc/hosts.equiv will have following entry. infserver if using option b) then informix user's ( on server1) $HOME/.rhosts would contain following entry. infserver. Things to keep in mind. a) /etc/hosts.equiv is potential security hazard. b) User Informix should exist on both the servers, though on server1 (as per above example), need not have Informix software installed. Just the user is enough. Warnings. : The above may not work if you are using DNS. I believe the procedure is different. Also, in future do specify the hardware platform, O/S, and Informix versions. It will help much more in solving such problems. The above illustration is true for HP E series machines running HP/UX 9.04 and Informix 5.
