Running shell script on different server

Hi,

I am new to Unix and was wondering whether it is possible to call a shell script on a different server?

(The reason I want to do this is that I have written some Java code that will only run on the Java 1.5 Virtual Machine, but the Production server is Solaris 2.6, which won't run the 1.5 JVM. I therefore need to have the Java on a newer machine. The shell script that calls the Java is called by some Pro*C code)

thanks in advance for your help

Yes, but you will need to set up some form of trust, unless you wish to type in passwords each time you do this.
Best way is to use ssh (part of OpenSSH). I do not know about Solaris 7 but I know you can get OpenSSH on Solaris 8 (though not supported by Sun). If the users are the same on both servers it is not too hard to do.
Failing that it would be via the use of .rhosts - not the bets way to do anything and usign the rsh (or remsh) command.

I agree 100% with Ehlanna on the rsh front. I'd like to add my caution too. If this is a strictly internal application on an internal network then you could just do an:



assuming that paths and the like were set up correctly. As Ehlanna mentioned you may want to set up ~/.rhosts so that the password is not required.

But, again, this is a pretty dangerous configuration. For all practical purposes you're turning security off.

I don't know enough about your code but it seems like if you're stuck with an ancient O/S for production then it may make more sense to rethink your design a bit. Solaris 2.6 isn't supported under 1.4 either so you must be using 1.3. 1.3 has entered Sun's EOL meaning that when Mustang (1.6/6.0) is released 1.3 will no longer be supported without a support contract.

The environment you have is creating dangerous security practices because of it's age. I realize you very well may not make the O/S revision decision but that choice is quickly becoming obsolete. You're 4 major O/S releases behind. The problems you're trying to solve are all tied to this ancient O/S. Is there any way to convince the powers that (at least think they) be that it is time to move into the new millennium? Solaris 2.6 was released 9 years ago this month!

Thanks for your replies guys- they're really useful.

There is a plan to upgrade the server, but this won't happen til January at earliest; the java needs to go live in September.

Thanks once again
