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

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 :
First i searched for libproxychains.so.3 location :
whereis libproxychains.so.3
Output :
libproxychains.so: /usr/lib/x86_64-linux-gnu/libproxychains.so.3
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 [ $# = 0 ] ; then
echo " usage:"
echo " proxychains <prog> [args]"
exit
fi
export LD_PRELOAD=libproxychains.so.3
exec "$#"
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
