On a user's 4.0g system, we are having trouble with the passwd command. I
have received some
information that there may be a patch, but searching all the 4.0g patches
turned up nothing.
Symptom: when you do: # passwd FooBar
nothing happens, it does not hang, it simply gives you back the shell
prompt: #
It never prompts for any password.
Has anyone else seen this problem?
Can you compare our binary to yours?
How to compare our binary to yours:
----------------------------------------------------
Its easy to do, if we compare checksums.
To make it easy to compare our /usr/bin/passwd against yours, here is what I
did: I ran sum
on passwd and the c-runtime-lib. If you run command "ldd" on
/usr/bin/passwd you will see that
it depends on the C lib.
1. below you will see our sum output.
2. can you compare to your output from sum to ours?
3. if you get different values for the /usr/bin/passwd command on 4.0g, can
you email me the /usr/bin/passwd
binary [its only 16k bytes in size].
==> details
Commands to compute checksum data:
To quickly verify if the passwd file differs from our system, you can use
the sum command.
The SUM {checksum} data regarding the version of passwd command on your
system can be obtained like this:
do : NOTE: the password command "passwd" may be only readable from the
root account
also note that emailing the passwd command is perfectly safe as it has no
useraccount or
password data from the system.
%
% su -
# sum /usr/bin/passwd
# ^D
%
sum of passwd on the system having a problem returns=> 45835 32
passwd uses the C run time library. You can see this by running command:
#
# ldd /usr/bin/passwd
#
If you run sum on the library, can they compare to :
sum std-C-library => 58345 3268
and tell us if its different?
