SSH 連接因 shell 無法載入而關閉

我有使用 OpenSSH 執行的 FreeBSd。我設置了所有內容，並且通過 SSH 的連接執行良好。然後我決定擺脫一些未使用的埠，我顯然解除安裝了一個 zsh 使用的埠。

當我登錄時，我得到以下資訊：

~ # ssh cristian@192.168.1.56

Welcome to FreeBSD!

Before seeking technical support, please use the following resources:

o  Security advisories and updated errata information for all releases are
  at http://www.FreeBSD.org/releases/ - always consult the ERRATA section
  for your release first as it's updated frequently.

o  The Handbook and FAQ documents are at http://www.FreeBSD.org/ and,
  along with the mailing lists, can be searched by going to
  http://www.FreeBSD.org/search/.  If the doc package has been installed
  (or fetched via pkg_add -r lang-freebsd-doc, where lang is the
  2-letter language code, e.g. en), they are also available formatted
  in /usr/local/share/doc/freebsd.

If you still have a question or problem, please take the output of
`uname -a', along with any relevant error messages, and email it
as a question to the questions@FreeBSD.org mailing list.  If you are
unfamiliar with FreeBSD's directory layout, please refer to the hier(7)
manual page.  If you are not familiar with manual pages, type `man man'.

Edit /etc/motd to change this login announcement.

Shared object "libiconv.so.3" not found, required by "zsh"Connection to 192.168.1.56 closed.

問題是我沒有顯示器，也沒有鍵盤（現在）可以很快解決問題……

我試過這個來強制載入不同的 shell >強制 SSH 使用特定的 shell

我得到的不起作用：

~ # ssh cristian@192.168.1.56 /usr/local/bin/sh << EOF
chsh -s /usr/local/bin/bash
EOF
Password:
Shared object "libiconv.so.3" not found, required by "zsh"%    

任何想法如何在沒有鍵盤和顯示器的情況下解決它？

我曾經犯過同樣的錯誤。我懷疑您是否能夠獲得遠端更改 shell 所需的 root 訪問權限。另一個不太可能的選擇是破解你自己的盒子並獲得 root 權限。

我必須通過鍵盤和監視器在本地連接並更改為預設外殼。永遠不要讓 root 使用使用者態 shell。始終讓 root 使用系統自帶的預設 shell。如果您需要或想要使用不同的 shell，請在登錄後手動啟動它。這就是我現在所做的。

make delete-old-libs請記住，/usr/src除非您絕對知道您將不再需要這些庫，否則不要這樣做：-D
