我无法打开 duckduckgo 或任何带有代理链的网站，如图所示，并且由于某种原因，其末尾有一个数字 4。图片
/etc/proxychains4.conf
# proxychains.conf VER 4.x
#
# HTTP, SOCKS4a, SOCKS5 tunneling proxifier with DNS.
# The option below identifies how the ProxyList is treated.
# only one option should be uncommented at time,
# otherwise the last appearing option will be accepted
#
dynamic_chain
#
# Dynamic - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped)
# otherwise EINTR is returned to the app
#
#strict_chain
#
# Strict - Each connection will be done via chained proxies
# all proxies chained in the order as they appear in the list
# all proxies must be online to play in chain
# otherwise EINTR is returned to the app
#round_robin_chain
#
# Round Robin - Each connection will be done via chained proxies
# of chain_len length
# all proxies chained in the order as they appear in the list
# at least one proxy must be online to play in chain
# (dead proxies are skipped).
# the start of the current proxy chain is the proxy after the last
# proxy in the previously invoked proxy chain.
# if the end of the proxy chain is reached while looking for proxies
# start at the beginning again.
# otherwise EINTR is returned to the app
# These semantics are not guaranteed in a multithreaded environment.
#
#random_chain
#
# Random - Each connection will be done via random proxy
# (or proxy chain, see chain_len) from the list.
# this option is good to test your IDS :)
# Make sense only if random_chain or round_robin_chain
#chain_len = 2
# Quiet mode (no output from library)
#quiet_mode
#Proxy DNS requests - no leak for DNS data
proxy_dns
# set the class A subnet number to use for the internal remote DNS mapping
# we use the reserved 224.x.x.x range by default,
# if the proxified app does a DNS request, we will return an IP from that range.
# on further accesses to this ip we will send the saved DNS name to the proxy.
# in case some control-freak app checks the returned ip, and denies to
# connect, you can use another subnet, e.g. 10.x.x.x or 127.x.x.x.
# of course you should make sure that the proxified app does not need
# *real* access to this subnet.
# i.e. dont use the same subnet then in the localnet section
#remote_dns_subnet 127
#remote_dns_subnet 10
remote_dns_subnet 224
# Some timeouts in milliseconds
tcp_read_time_out 15000
tcp_connect_time_out 8000
### Examples for localnet exclusion
## localnet ranges will *not* use a proxy to connect.
## Exclude connections to 192.168.1.0/24 with port 80
# localnet 192.168.1.0:80/255.255.255.0
## Exclude connections to 192.168.100.0/24
# localnet 192.168.100.0/255.255.255.0
## Exclude connections to ANYwhere with port 80
# localnet 0.0.0.0:80/0.0.0.0
## RFC5735 Loopback address range
## if you enable this, you have to make sure remote_dns_subnet is not 127
## you'll need to enable it if you want to use an application that
## connects to localhost.
# localnet 127.0.0.0/255.0.0.0
## RFC1918 Private Address Ranges
# localnet 10.0.0.0/255.0.0.0
# localnet 172.16.0.0/255.240.0.0
# localnet 192.168.0.0/255.255.0.0
# ProxyList format
# type ip port [user pass]
# (values separated by 'tab' or 'blank')
#
# only numeric ipv4 addresses are valid
#
#
# Examples:
#
# socks5 192.168.67.78 1080 lamer secret
# http 192.168.89.3 8080 justu hidden
# socks4 192.168.1.49 1080
# http 192.168.39.93 8080
#
#
# proxy types: http, socks4, socks5
# ( auth types supported: "basic"-http "user/pass"-socks )
#
[ProxyList]
# add proxy here ...
# meanwile
# defaults set to "tor"
socks4 127.0.0.1 9050
socks5 127.0.0.1 9050
更新：我卸载了它然后重新安装它，但仍然不起作用图像
更新 2：我尝试了不进入 root 权限的方法，并且成功了。但这有什么区别吗？
答案1
我在 kali linux 上遇到了完全相同的问题（2021 年 12 月 27 日）。我猜测我需要给它指示如何显示，因此我将命令修改为：proxychains firefox openwww.duckduckgo.com
并且它通过简单地添加“打开”起作用它确实打开了第二个选项卡，所以我不确定这是默认设置还是需要更多调整，但它打开了页面并且代理链起作用了。
