[gentoo-user] rsh failed : Connection reset by peer
Hi,
I want to use iozone to test my cluster, and I found that iozone need
rsh. But rsh never worked in my machine.
I have followed this guide
http://www.gentoo.org/doc/en/hpc-howto.xml#doc_chap2, which including
the configuration of rsh.

}
I have a node07 whose is is 192.168.1.7 and a master, whose ip is 192.168.1.1.
I tried to rlogin to master from node73 with any user (i mean both
root and other users), I got the error in node07:
node07 # rlogin -l root master
rcmd: master: Connection reset by peer
and I read the log from /var/log/rlogin in master:
# cat /var/log/rsh

09/1/5...@23:10:36: EXIT: login status=0 pid=8961 duration=0(sec)
And the master can't rlogin to itself, too: with root, because t:

I am sure the password is correct */

Anybody can help?

I tried to rlogin(rlogin -l myuser host) and rsh(rsh -l myuser host
date) from the remote machine 192.168.0.7 and from localhost. Here is
the log:
# cat /var/log/rsh

So in a word, I can rlogin from localhost with common user(I meant not
root) but not from remote machine 192.168.0.7. And I can't use rsh at
all.
So anyone can help?
PS:
I just want to use iozone, and I am not very sure whether I can ssh in
the iozone clusting test or not. If I can use ssh without changing the
source of iozone(iozone is a benchmark tool, so I don't think it's a
good idea to change it), please let me know.
Thanks in advanced!
