sshuttle がエラーになる

SSH VPN がお手軽に利用できる sshuttle を久々に使おうとしたら失敗します.いくつかのremotehostを試してもうまくいかない.

Debian sid 環境でのエラー

最後の行のエラーメッセージで検索すると以下のIssue を見つけました.

参考にして -x remotehostip で使えるようになりました.-x は除外オプションで接続先のip を指定して除外するとOKのようです.

  • NG $ sshuttle -r user@remotehost 0/0

  • OK $ sshuttle -r user@remotehost 0/0 -x remotehostip

VPN 対象のサブネットと同様 -x にも複数のサブネット/ip の指定ができます.

Debian sid 環境
$ dpkg-query -W sshuttle
sshuttle        0.78.5-1
$ hostnamectl|grep -E 'Operating System|Architecture'

Raspbian Buster 環境でのエラー

ちなみに sshuttle を Raspbian Buster で試すとまた違うこんなエラーに.でもやっぱり -x で解決しました.

Ubuntu 18.04 LTS 環境(OK)

Ubuntu 18.04 LTS のsshuttle でも試してみましたがこれは -x を付けなくても問題なしでした.sshuttle 0.78.4 〜 0.78.5 の間の修正での影響でしょうか?

error の出なかった環境
$ dpkg-query -W sshuttle
