massy · 10-15-2014, 06:07 AM

I can't run commands like as:
ls, yum, rpm, ./configure, and...
The error is shown:
error while loading shared libraries: libcap.so.2: cannot open shared object file: No such file or directory

How did you remove it? First recommendation is to reverse that. If you did a rm of that and a variety of files, you can run package manager to fix and force reinstallation of the appropriate packages.

I've used rpm --nodeps -e libcap. RPM and yum doesn't work!!!

you need another host, download the package itself, unpack and copy the file libcap.so.2 into the system. That may allow to reinstall that package. Just copying the file is not sufficient.

Either that or download the source for libpcap, then make and install it.

where should I copy it?

pan64 · 10-15-2014, 07:10 AM

it depends on your installation, probably: /lib/libcap.so.2 or /lib64/libcap.so.2 or /lib/x86_64-linux-gnu/libcap.so.2 or /lib/i386-linux-gnu/libcap.so.2
I'm not really sure, I would try /lib first.

rtmistler · 10-15-2014, 07:20 AM

The path should be: /usr/lib/<system-type>-linux-gnu for instance i386 as the system-type. An issue here is that if you download/install on a parallel system, you potentially need the same kernel version, at the very least you need the same libpcap version you had before. That's why I wonder if it's better to try and get the source and then build and install it on your system where the problem is.

Thank you, so much.

I did not tell him to install it, just download and unpack the given package. Of course the same version - if he was able to identify.

I have no idea which one is the better (make/make install from source or just do that trick to be able to reinstall).
