SNX：接続が中断されました。

私の最終目標は、SSHを介してのみアクセスできるUbuntu 16.04を実行しているサーバーのCheckPoint VPNの背後にあるFTPサーバーからファイルをダウンロードすることです。

私は次の手順に従いました。この回答、具体的に：

1. snxバージョン 800007075 のインストール

wget https://starkers.keybase.pub/snx_install_linux30.sh?dl=1 -O snx_install.sh

2. 依存関係をインストールします。

sudo apt-get install libstdc++5:i386 libx11-6:i386 libpam0g:i386

3. 走る

chmod a+rx snx_install.sh
sudo ./snx_install.sh

4. ファイルを生成します~/.snxrc。

server <server_ip>
username <vpn_user>
reauth yes

それ以降（そしてステップ4より前）に試みるたびに、次のような結果がsnx -s <server_ip> -u <vpn_user>得られます。

Check Point's Linux SNX
build 800007075
Please enter your password:

ここでの出力はsudo ldd /usr/bin/snx次のとおりです。

私は何を逃したことがありませんか？
