UNIX for Dummies Questions & Answers

what should i use if i want to run a shell script from a remote host where in it requires me to enter a username and a password which is different from my present login and run a shell located in that server? should the script located on the local or remote end? something that will do something like this:

server1:/home/usrinquirer>xhost +
access enabled blah! blah! blah!
server1:/home/usrinquirer>rlogin server2
password:(ENTER)
login:usrman
password:password
...
...
server2:/home/usrman>date
server2:/home/usrman>sh server2.sh

i've tried including rlogin in the script but how can i change from one user from another? i've tried using rlogin server2 -l usrman/password (and a like with remsh) but it did not work, if i remove password it will give me an error "login incorrect". what will i do?

thanks.

To enable remote logins without asking password, you must configure rhosts. you must create a file named .rhosts in the user's home dir containing the hostname of the machine you want to to alow remote login. man rhosts woud help you. About your scripts, if you want only to execute scripts in remote hosts, try using rsh. man rsh can help you.

Any questions, tell me.

i tried to read man page of rhosts but still unable to understand that thingy... i've never tried this before so could you please help me on this? can you give me some example where in i can do exactly what i meant in my first question? please? i need this very much in order to perform many stuffs in the office. appreciate your assistance

Remote Server : - ABC
Local Server :- XYZ

User in ABC :- john
User in XYZ :- rex

U are logged in as rex in XYZ and want to connect to ABC as john

So wat u do
XYZ> rlogin ABC -l john
Password:
ABC> finger
Check out wat u have in the (where) field for the current (tty)
Lets say u get
Login Name TTY Idle When Where
lhuang lihong huang dtlocal 10 Tue 18:46 a.b.c.d

ABC> vi .rhosts ( make sure u are in home dir of john)

enter the following in there

a.b.c.d(The where field above) rex

Save it

ABC> exit
Connection Closed
XYZ>rlogin ABC
Connected
ABC>

Any Doubts?

i just got off from work and tried your suggestion but when i tried to finger the remote host it gave me this:

Login Name TTY Idle When Bldg. Phone

usrno1 usrno1 *te 1:00 Wed 17:41
usrrex REX101 *4 1d Tue 10:30

the where field is blank and does not contain any information i tried some variation but it just not seem to work how should i do this? how about the password because everytime we remote log it ask for the password regardless if you are trying to remote log the same user but different server. please help

Ok Then use -- from -- field from the output of
%> w

Not every platform gives host information in the w/finger output.

To the original poster: put the IP address of machine XYZ in the .rhosts file on ABC.

Example:

192.168.0.1 rex
