Ntp dependency with libcrypto.so.4

smallbook · 01-09-2008, 03:53 AM

Hi everyone, i am fairly new in this forum. I have problem setting up ntpdate on one of my servers, a dell power edge that runs redhat ES version 4. I have configured /etc/ntp.conf but when i tried to start up ntpd using service ntpd start, this error pops up :
service ntpd start
Starting ntpd: ntpd: error while loading shared libraries: libcrypto.so.4: cannot open shared object file: No such file or directory
[FAILED]

This only happens after i have upgraded from ES version 4 to ES version 4. I did copy the libcrypto.so.4 (that points to the file libcrypto.so.0.9.7a) from other servers to this one and tried to restart but to no avail. Strangely, i did the same thing to another server that failed with the same message but it worked. However, this time it doesn't work anymore. Any idea what could have caused it?

Welcome to LQ!

First, make sure your symlinks are still valid after copying. Example below shows sometimes there may be more than one symlink.

Code:

~ $ ls -l /lib/libuuid*
lrwxrwxrwx 1 root root    12 2008-01-01 12:16 /lib/libuuid.so -> libuuid.so.1
lrwxrwxrwx 1 root root    14 2008-01-01 12:16 /lib/libuuid.so.1 -> libuuid.so.1.2
-rwxr-xr-x 1 root root 13824 2008-01-01 12:16 /lib/libuuid.so.1.2

Second, you must run ldconfig after installing new libraries manually.

HI Emerson, thanks for your warm welcome

I have ensured that the symbolic links are there:

ls -al /lib/libcrypto.so.4
lrwxrwxrwx 1 root root 19 Jan 9 17:25 /lib/libcrypto.so.4 -> libcrypto.so.0.9.7a

ls -al /lib64/libcrypto.so.4
lrwxrwxrwx 1 root root 19 Jan 9 17:25 /lib64/libcrypto.so.4 -> libcrypto.so.0.9.7a

and, the file libcrypto.so.0.9.7a is also there:

ls -al /lib/libcrypto.so.0.9.7a
-rwxr-xr-x 1 root root 972156 Jan 9 17:32 /lib/libcrypto.so.0.9.7a

ls -al /lib64/libcrypto.so.0.9.7a
-rwxr-xr-x 1 root root 1236736 Jan 9 17:31 /lib64/libcrypto.so.0.9.7a

I did try running ldconfig but still the output is the same when i tried to start up ntp:
service ntpd start
Starting ntpd: ntpd: error while loading shared libraries: libcrypto.so.4: cannot open shared object file: No such file or directory
[FAILED]

Anymore suggestions or any ideas? I am going to upgrade other servers to version 4 too and i am afraid other servers will encounter the similar problem and i wouldn't be as lucky as the first time where i managed to just copy over libcrypto.so.0.9.7a from other working servers and got ntpd running.

Well, correct solution would be installing libcrypto in RH way (whatever it is, I'm not familiar with it). I wonder why it does not install it automatically with ntpdate as dependency.

Hmm so i should load in the installation CD and install the lib ?

Emerson · 01-10-2008, 07:25 PM

Yep, you could also try uninstalling and reinstalling ntp, maybe it pulls in libcrypto then. And you could call RH, the whole idea behind having RH Linux is to have support, so why not use it when needed.

Thanks Emerson, i will try to reinstall ntp, what about reinstalling the libcrypt or crypt-setup because when i tried to install it says all these have been installed.
