HP-UX

hello,
i have 4 hp-ux servers (srv1,srv2,srv3,srv4)
srv1 is used to remsh srv2,srv3,srv4

/etc/hosts is configured on all servers and they can ping each other by ip,hostname and alies

in srv2,srv3,srv4, .rhosts file is configured in user home with the entry:
srv1 srv1_user

/etc/inetd.conf is checked

as srv1_user on srv1, i tested remesh to all other servers:

Code:

 
srv1> remsh srv2 -l srv2_user uname -n
srv2 
 
srv1> remsh srv3 -l srv3_user uname -n
srv3
 
srv1> remsh srv4 -l srv4_user uname -n
remshd: Login incorrect.

srv4 can remsh srv1

Code:

srv4> remsh srv1 -l srv1_user uname -n
srv_1

i made sure about /etc/hosts and .rhosts files
but i cannot remsh from srv1 to srv4

is there service has to be started on srv4 or how to make sure that all needed services for remsh are up .. what am i missing

thank you

Try to connect to srv4 using remsh:

Code:

remsh srv4

It should at least ask you the passwd...
If after giving the (good) passwd it works, it leaves you with perms issue on .rhosts or..
If you dont even get there, then you may have the service denied (remsh not a valid login...) you would have to look at /var/adm/inetd.sec

hi vbe..
with command in remsh it gives incorrect login:

Code:

 
srv1> remsh srv4 -l srv4_user uname -n
remshd: Login incorrect.

if i omit the command (uname -n) in remsh,

Code:

 
srv1> remsh srv4 -l srv4_user
Password:
srv4>

if omit user_name and command: (user in srv1 is different from srv4 which defined in .rhosts)

Code:

 
srv1> remsh srv4 
Password:
Login:
Password:
srv4>

all .rhosts files in all servers has 700 permission (for srv4 the owner of .rhosts is srv4_user and so on)

(The .netrc process does not resolve aliases).

When logged in to server "srv4" issue "nslookup srv1" .
If it fails, fix /etc/hosts or your DNS according to circumstances.
If it works, whatever "nslookup" replies with as the "Name:" is the server name to put in the "srv1_user" line of the ".rhosts" file in the home directory of account "srv4_user" on server "srv4".

i.e. It is quite possible to "remsh" to a server by name but the ".rhosts" on the target computer contains a different name for the source computer. It must be possible to resolve the name of the source computer on the target computer.

Btw. Permissions for .rhosts should be 600 not 700. It must not be a link.

Make sure that the line in "/etc/inetd.conf" on "srv4" containing "remshd" is identical to the other servers and does not contain a "-l" switch (which would disable .rhosts processing).

hi methyl
- The name in nslookup is used in .rhosts
- 700 permission works with other servers. however i changed it to 600 (and 777 to test)
- remshd entry in /etc/inetd.conf is same as other servers

still not working.

But in your last login using remsh in your previous post what user did you enter (you say nothing...) and was it successful?
Did you have a look at inetd.sec?

(I tend you use 640 perms on .rhosts...)
