Linux to HP-UX remsh backup

[Ronald Angel]

I'm attempting to back up a Linux machine to one of our HP-UX 11.0 machines using tar & remsh. I get "remshd: Couldn't look up address for your host". nslookup returns the correct name & IP on both systems for both systems. Any ideas?

[Vitaly Karasik_1]

what about reverse resolution?

nslookup xx.yy.zz.xx ?

set up the .rhosts files or /etc/hosts.equiv files with IP addresses instead of hostnames.

Then if there is a reallignment of your network names or your DNS server goes down this process will still work.

Openssh and Secure Shell(HP-UX) is a much more secure way to accomplish the same thing without the vulnerabilities involved in your current process.

I'm attaching a doc on password free public key exchange that works on both platforms(I tested it).

remshd, by default, tries to do a reverse lookup on a host's IP address (i.e., 192.168.0.4 -> myhost.somedomain.com).

You can disable this by specifying the -s option for remshd in /etc/inetd.conf

shell stream tcp nowait root /usr/lbin/remshd remshd -s

(providing you have current patches applied for the r-cmds; the unpatched version of 11.0 does not have this option)

If you have control over DNS, then you could add reverse look-up records for your Linux machine.

I remsh daily from my linux host to all our HP-UX servers.

I found that in some boxes you have to put the FQDN of the linux box in the .rhosts file. NOt sure why that happens, been over lots of config issues.

anyway, the fasted way to get remsh to work,

is

create a dot r hosts file on the remote machine and add the line



save the file, chmod 400 .rhosts

done,



peace
