tsocks.conf

[m.]

Is there any way for tsocks to read user-defined config file instead of /etc/tsocks.conf?
I have login/password for proxy in this file and don't want it to be readable by anybody else but me.. something like $HOME/.tsocks.conf would be fine..
Thanks

I am also interested in a ~/.tsocks.conf file that would trump the defaults at /etc/tsocks.conf ... this is standard convention and I am surprised that it is not in place, especially when there are issues with root using tsocks to begin with.

I would also like command-line arguments that can trump the configuration file(s), like
  tsocks --server=127.0.0.1:1080 --type=5 telnet 192.168.0.1
or the shorter
  tsocks -s 127.0.0.1:1081 -t5 telnet 192.168.0.1

Hell, I'll even help on the shell scripting side ... I just can't contribute to the library.

If my code gets mangled here, I may give up.  Nobody is reading this anyway.

#!/bin/sh

# read in application defaults here

  # these are dummy defaults so that you can test properly
  local=127.0.0.0/255.0.0.0
  server=default-server
  type=5
  port=1080

# read in default config (/etc/tsocks.conf) here (overriding app defaults)

# read in user config (~/.tsocks.conf) here (overriding system defaults)

# now we read in the command line arguments to override the above

# display 1st arg when it exists and is unique, otherwise second arg and FALSE
get_value() {
  if [ -n "$1" ] && [ "$1" != "$2" ]
    then echo "$1"
    else echo "$2"; false # this return value is used below to shift arguments
  fi
}

while true; do
  case $1 in
    --server* ) server=`get_value "${1#--server=}" "$2" || shift` ;;
    -s* | -d* ) server=`get_value "${1#-[sd]}"  "$2" || shift` ;;
    --port* )   cport=`get_value "${1#--port=}" "$2" || shift` ;;
    -p* )       cport=`get_value "${1#-p}"      "$2" || shift` ;;
    --type* )   type=`get_value "${1#--type=}"  "$2" || shift` ;;
    -t* )       type=`get_value "${1#-t}"       "$2" || shift` ;;
    --local* )  local=`get_value "${1#--local=}" "$2" || shift` ;;
    -l* )       local=`get_value "${1#-l}"      "$2" || shift` ;;
    * )         break ;;
  esac
  shift
done

# if syntax is "server:port" then separate into server and port
p="${server#*:}"
server="${server%:*}"
[ -z "$cport" ] && [ "$server" != "$p" ] && cport="$p"
[ -n "$cport" ] && port="$cport"

echo "server: '$server'"
echo "port: '$port'"
echo "type: '$type'"
echo "local net: '$local'"
echo "execute code: '$@'"
echo "(note, execute code will actually be passed with correct quoting)"

that cool logic with shift doesn't work in a subshell (back-ticked command substitution). 
also note that indentation was removed and spacing truncated (likely anti-ascii porn) :-(

fix:

#!/bin/sh

# read in application defaults here

  # these are dummy defaults so that you can test properly
  local=127.0.0.0/255.0.0.0
  server=default-server
  type=5
  port=1080

# read in default config (/etc/tsocks.conf) here (overriding app defaults)

# read in user config (~/.tsocks.conf) here (overriding system defaults)

# now we read in the command line arguments to override the above

# display 1st arg when it exists and is unique, otherwise second arg and FALSE
get() {
  [ -n "$1" ] && [ "$1" != "$2" ] && echo "$1" || echo "$2"
}

while true; do
unset r
case $1 in
--server* ) server=`get "${1#--server=}" "$2"`; [ "$server" = "$2" ] && r=2 ;;
-s* | -d* ) server=`get "${1#-[sd]}"     "$2"`; [ "$server" = "$2" ] && r=2 ;;
--port* ) cport=`get "${1#--port=}"      "$2"`; [ "$cport"  = "$2" ] && r=2 ;;
-p* )           cport=`get "${1#-p}"     "$2"`; [ "$cport"  = "$2" ] && r=2 ;;
--type* ) type=`get "${1#--type=}"       "$2"`; [ "$type"   = "$2" ] && r=2 ;;
-t* )           type=`get "${1#-t}"      "$2"`; [ "$type"   = "$2" ] && r=2 ;;
--local* ) local=`get "${1#--local=}"    "$2"`; [ "$local"  = "$2" ] && r=2 ;;
-l* )           local=`get "${1#-l}"     "$2"`; [ "$local"  = "$2" ] && r=2 ;;
* )  break ;;
esac
shift $r
done

# if syntax is "server:port" then separate into server and port
p="${server#*:}"
server="${server%:*}"
[ -z "$cport" ] && [ "$server" != "$p" ] && cport="$p"
[ -n "$cport" ] && port="$cport"

echo "server: '$server'"
echo "port: '$port'"
echo "type: '$type'"
echo "local net: '$local'"
echo "execute code: '$@'"

Four years after the initial query, two years after my pondering, I discover that the actual tsocks program is itself a posix script, and that libtsocks works fully via shell environment variables, including on that sets the tsocks configuration file.  I'm also a far better scripter these days.

I have fully implemented ALL configuration options on the command line, plus several various configuration file manipulators (alternate config file, save command line in config file, etc), help, descriptions, and more.

I still use this regularly and it still works swimmingly. It is now a part of my net-scripts repository on GitHub.
