UNIX for Dummies Questions & Answers

I have a Windows batch file with the below entry for auto login.

Code:

putty.exe -ssh user1@10.10.10.7 -pw passwd1 -m command.txt

commnd.txt contains the below entries

Code:

pwd
sudo su - user2

Switching from user1 to user2 does not require any password [auto switch].

Output just prints the pwd and not sudo

When i do this manually it works, but when i tried to automate as above the putty session sort of freezes.

OS: SunOS Sprac IP: 10.10.10.7

Any clues / Alternate workarounds ?

whether your client machine using public ip ? if so then it hangs sometimes... it must be doing reverse dns lookup I guess..

check dig -x clientip

If you're trying to automate it, plink may be more reliable than putty. (Derived from the same program, available from the same source.)

plink also freezes the same way as putty.

dg command not found !!

man su:

Code:

           When - is used, it must be specified as the last su option. The other forms (-l and --login) do not have this restriction.

I did not get much of what you said ... but what i could understand is that I should try sudo su user2 instead of sudo su - user2

I tried, but that too did not help !! Any suggestions ?

Can you see the output of pwd? Or just the words "pwd"? Your shell might not be starting correctly causing a hang in the session. Try executing the command without the su part and confirm you are able to login. If anything add a sleep, it may need sometime to log in and load the shell.
