Hi, I want to use iozone to test my cluster, and I found that iozone would use 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} # 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 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 08/10/[EMAIL PROTECTED]:58:39: START: shell pid=23802 from=127.0.0.1 08/10/[EMAIL PROTECTED]:58:48: EXIT: shell status=1 pid=23802 duration=9(sec) 08/10/[EMAIL PROTECTED]:58:53: START: shell pid=23857 from=127.0.0.1 08/10/[EMAIL PROTECTED]:58:59: EXIT: shell status=1 pid=23857 duration=6(sec) 08/10/[EMAIL PROTECTED]:17:21: START: shell pid=26446 from=192.168.0.7 08/10/[EMAIL PROTECTED]:17:21: FAIL: shell address 08/10/[EMAIL PROTECTED]:17:21: EXIT: shell status=0 pid=26446 duration=0(sec) # cat /var/log/rlogin 08/10/[EMAIL PROTECTED]:19:04: START: login pid=26727 from=192.168.0.7 08/10/[EMAIL PROTECTED]:19:10: FAIL: login address 08/10/[EMAIL PROTECTED]:19:10: EXIT: login status=0 pid=26727 duration=6(sec) 08/10/[EMAIL PROTECTED]:39:31: START: login pid=28886 from=127.0.0.1 08/10/[EMAIL PROTECTED]:39:40: EXIT: login status=0 pid=28886 duration=9(sec) 08/10/[EMAIL PROTECTED]:39:46: START: login pid=28912 from=127.0.0.1 08/10/[EMAIL PROTECTED]:39:47: EXIT: login status=0 pid=28912 duration=1(sec) 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! -- wcw
