How to resolve this error "ERROR: ld.so: object 'xxx' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored. " [closed]

Question

To utilize the proxy on my Ubuntu system, I required the installation of proxychains. Here are the steps I took:

1. sudo apt-get install proxychains
   

2. sudo vim /etc/proxychains.conf
   ...
   [ProxyList]
   socks5 192.xxx.xxx.xxx 1080
   

3. sudo vim /usr/bin/proxychains
   ...
   #export LD_PRELOAD=libproxychains.so.3
   export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3
   

Then I run proxychains curl www.google.com, the proxy doesn't work but there's no error. When I run sudo proxychains curl www.google.com, there's the error:

ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libproxychains.so.3' from LD_PRELOAD cannot be preloaded (failed to map segment from shared object): ignored.
ERROR: ld.so: object '/usr/lib/x86_64-linux-gnu/libproxychains.so.3' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

How can I fix this issue and run proxychains successfully? Thanks a lot.

Answer 1

Try

export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libproxychains.so.3.0.0

this is the correct libraryname on Ubuntu (it reports "cannot open shared object file")

Answer 2

I was able to solve the issue by identifying a problem with my 'curl'. After reinstalling it, everything is running smoothly now.
