Title: Problem with ssdp script.
Post by: UndyingHippocracy on March 01, 2015, 02:29:17 AM

(OS: CentOS 6)
Recently I've been trying to run my ssdp scanner off of my VPS and this has been the result everytime:


./ssdpscan: error while loading shared libraries: libpcap.so.0.8: cannot open shared
object file: No such file or directory.


I uploaded the file from my VM to the VPS through the FTP and used "sudo chmod +x ./ssdpscan" to make he application.
I don't know what the issue is because I checked to see if libpcap needed to be updated
and it is currently on the latest version. (I'm on an ssh terminal btw) please if anyone has a solution to this tell me.

Which is means "libpcap is not installed". Try yum install libpcap to install the library.

Nothing to do

Then you have different version of libpcap in your system, I guess newer version.

You can create a symlink from your existing version to the new one using ln -s <source> <target> command.

usage something like:
ln -s /usr/lib/libpcap<your_version> /usr/lib/libpcap.so.0.8

You can check libpcap version by ls /usr/bin/libpcap*
Obviously, you have 1.4.0-1 version but your libpcap file can be named differently.

I'm still getting the same error, do you think that this might be
happening because I'm on an OVH VPS?

No.

Could you please show me output of ls -l /usr/lib/libpcap*

symlink is wrong.

create symlink with source libpcap.so.1

Post by: UndyingHippocracy on March 01, 2015, 07:23:34 AM

I used:
ln -s /usr/lib/libpcap.so.1 /usr/lib/libpcap.so.0.8


and it's giving me the same error still

Could you show me output of previous (ls -l ...) command? Just to be sure that you did symlink right.

And if symlink was created without errors then I guess it's not possible to see "No such file or directory" error

do you see this awesome RED line? It means that symlink is wrong.

How you didn't notice error that symlink already exist when you executed ln -s command?

You need to:
- remove wrong symlink
- create new one again.

ok so...

Title: Re: Problem with ssdp script.
Post by: KryDos on March 01, 2015, 07:49:07 AM

output seems good...

I don't know... try to copy all libpcap files to the ssdp directory.

cp -R /usr/lib/libpcap* <ssdp directory>

Title: Re: Problem with ssdp script.
Post by: UndyingHippocracy on March 01, 2015, 07:54:26 AM

Now by SSDP directory do you mean the directory for the script?

Ok so what would that be, the script is in "cd ~"

Now it seems like magic...

I found this in google:
yum install gcc libcap libpcap libpcap-devel

try to execute this command
