Packet Tracer Centos 7 error when executed.

Post by peli23 » 2018/08/13 10:06:47

Good morning everyone,

I am a newbie in Linux and I need the run Cisco Packet Tracer for taking CCNA certification. After installing Packet Tracer, I cannot execute the software because I am getting the error below in /lib64/libcrypto.so.1.0.0. Any suggestions on how to fix this issue?

[root@localhost bin]# ./PacketTracer7
./PacketTracer7: /lib64/libcrypto.so.1.0.0: no version information available (required by ./PacketTracer7)
./PacketTracer7: /lib64/libcrypto.so.1.0.0: no version information available (required by /lib64/libQtNetwork.so.4)
./PacketTracer7: /lib64/libcrypto.so.1.0.0: no version information available (required by /lib64/libQtNetwork.so.4)
./PacketTracer7: /lib64/libcrypto.so.1.0.0: no version information available (required by /lib64/libssl.so.10)
./PacketTracer7: /lib64/libcrypto.so.1.0.0: no version information available (required by /lib64/libssl.so.10)
./PacketTracer7: relocation error: /lib64/libssl.so.10: symbol private_ossl_minimum_dh_bits, version libcrypto.so.10 not defined in file libcrypto.so.10 with link time reference
[root@localhost bin]#

This is the kernel I am running on my machine.

[root@localhost bin]# uname -r
3.10.0-693.17.1.el7.x86_64

Many thanks

See viewtopic.php?t=52256 but be aware that it is using non-CentOS packages. Possibly unmaintained, insecure non-CentOS packages.

The problem is that this program is built against the wrong version of openssl to run on CentOS. It needs to be rebuilt (by Cisco?) against the correct openssl version so that it runs without error. The posts above give a workaround but not a fix.
CentOS 5 died in March 2017 - migrate NOW!
