ERROR: ld.so: object 'libproxychains.so.3' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored

Question

When I type the command proxychains chromium on linux terminal

it gives me this error:

ERROR: ld.so: object 'libproxychains.so.3' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored. Opening in existing browser session.

what should I do in order to get rid of this error and make sure that proxychains work properly?

Answer 1

I've faced the same problem, when trying to run something like :

proxychains ping -c www.google.com  

but when trying to run something else like to get my public ip addr :

proxychains curl ifconfig.me 

surprisingly it works flawlessly

What i did to fix it was :

1. First i searched for libproxychains.so.3 location :

   whereis libproxychains.so.3  
   

   Output :

   libproxychains.so: /usr/lib/x86_64-linux-gnu/libproxychains.so.3
   

2. Next i took a look at the proxychains script /usr/bin/proxychains :

   sudo cat /usr/bin/proxychains
   

   Output :

    #!/bin/sh
    echo "ProxyChains-3.1 (http://proxychains.sf.net)"
    if [ $# = 0 ] ; then
        echo " usage:"
        echo "     proxychains <prog> [args]"
        exit
    fi
    export LD_PRELOAD=libproxychains.so.3
    exec "$@"
   

3. Edited the script sudo nano /usr/bin/proxychains and changed the export to include the absolute path to libproxychains.so.3:

    export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3
   

   like this :

    #!/bin/sh
    echo "ProxyChains-3.1 (http://proxychains.sf.net)"
    if [ $# = 0 ] ; then
        echo " usage:"
        echo "     proxychains <prog> [args]"
        exit
    fi
    export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3
    exec "$@"
   

Check again, the Error gone.

You can also install proxychains4 that it is better in my opinion (you can use both if you wanted)

to install proxychains4 : sudo apt install proxychains4
