Error In Rsh Connection, poll:protocol failure in circuit set
 

I wanted to setup the rsh service. But there is some problem.
the host name with rsh service is "netking",and the client name is "xxx"

When I input the command "rsh netking ls" in the netking which surpport the service,the work went well . however while I input the same command in the client ,the terminator showed the tips like :
rsh netking ls
poll:protocol failure in circuit set

Now I list the hosts and hosts.equiv in /etc
hosts:
127.0.0.1 netking
211.111.12.63 xxx

hosts.equiv:
netking
xxx

What's wrong with my system?
By the way ,my system is redhat9.0.

Take a look at this thread:

Other sources also mention permission problems.

Feed your searchengine with the following and you get some hits:

Hope this helps.

thanks a lot to the upstairs in advance!
I've read the link you introduced to me and done by fitterhappier's method.
but it doesn't work.
In rsh's work,there's something I still not sure!
Firstly , is there neccesary to add a same username in both the server and the client .
Secondly, when i input the comannd "rsh netking" in the client,the terminator showed the tips saying "passwd",then i try the server's root and a normal user's passwd ,but they didn't work, and the third time,the terminator ask me to input a username ,and i
have just done follow that ,finally the connection does work. In one word ,i can't rsh the server directely.It need input passwd. Is there something inproper with the server's
firewall or other things? If is firewall, how can i modify the firewall's setup?

No it's not. The -l <username> option can be used. Take a look at the manpage for more details.

If you omit the -l <username> part, rsh uses the name of the user executing the rsh command to execute the command on the other side. If that user does not excists, an error will occur. In this case you have to use the -l <username> option.

Before the command is remotely executed you need to give the appropriate password (the one for the remote user). This is normal behaviour. However, there are ways to automate this (I'm not going into that atm).

I'm don't think that the firewall is causing this.

Hope this helps.

I thinke you're right .But when i created a same username in the client and input the command "rsh netking pwd",it shouted at me the same tips.After that used "rsh netking"(of course i had used the same username to get in the client on the client side),and the same
situation appeared.

Sorry for my poor english, i can't understand your words "(I'm not going into that atm)".
And i wanted to take a try in this way.But i couldn't make it work by "setup" on the terminator.when i changed the firewall's setup , the next time i got in, everything was recoveried.In fact,i am setting the MPI's enviorament.From the http://www-unix.mcs.anl.gov/mpi/mpich/docs/faq.htm
i got the idea of shutting down my firewall.
but till now ,i can't shut down it yet.
i feel really hopeless.
Any way, thanks a lot of you. Druuna!

Sorry for the abbreviation. atm = at the moment.
I'm was just saying that it's a bit much to explain what you need to do to set it up without a password. You first need to get this running the way it should :)

I'm not familiar with MPI(CH), so I cannot help you with that.
It would be a good idea to shut down thw firewall and see if rsh is working. If it does, you know that the firewall is the cause of your problem.
