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. # eix netkit-rsh [I] net-misc/netkit-rsh Available versions: 0.17-r8 ~0.17-r9 {pam} Installed versions: 0.17-r8(08:51:30 10/20/08)(pam) Homepage: ftp://ftp.uk.linux.org/pub/linux/Networking/netkit/ Description: Netkit's Remote Shell Suite: rexec{,d} rlogin{,d} rsh{,d} # eix xinet [I] sys-apps/xinetd Available versions: 2.3.14 {perl tcpd} Installed versions: 2.3.14(09:02:57 PM 01/05/2009)(perl tcpd) Homepage: http://www.xinetd.org/ Description: powerful replacement for inetd # cat /etc/xinetd.d/rsh service shell { socket_type = stream protocol = tcp wait = no user = root group = tty server = /usr/sbin/in.rshd log_type = FILE /var/log/rsh log_on_success = PID HOST USERID EXIT DURATION log_on_failure = USERID ATTEMPT disable = no } # cat /etc/xinetd.d/rlogin service login { socket_type = stream protocol = tcp wait = no user = root group = tty server = /usr/sbin/in.rlogind log_type = FILE /var/log/rlogin log_on_success = PID HOST USERID EXIT DURATION log_on_failure = USERID ATTEMPT disable = no } 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: FAIL: login address 09/1/5...@23:10:36: START: login pid=8961 from=192.168.1.7 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: master # rlogin -l root localhost Password: Password: Login incorrect /*rlogin with root, the password is incorrect forever and Of course, I am sure the password is correct */ master # rlogin -l wcw localhost Password: Last login: Mon Jan 5 23:23:06 CST 2009 from localhost on pts/8 rlogin: connection closed. /*rlogin with other user(wcw), it will succeed, but the connection will closed immediately */ # cat /var/log/rsh [...] 09/1/5...@23:20:09: START: login pid=10227 from=127.0.0.1 09/1/5...@23:21:17: EXIT: login status=0 pid=10227 duration=68(sec) 09/1/5...@23:22:13: START: login pid=10954 from=127.0.0.1 09/1/5...@23:22:15: EXIT: login status=0 pid=10954 duration=2(sec) # cat /etc/hosts.allow ALL:192.168.1.0/255.255.255.0 # cat /etc/hosts.equiv master node07 Anybody can help?
