如果我的本地主机出现故障，我如何重新建立隧道？
我有 2 台机器，Remotehost 和 localhost，在我的 localhost 上运行 autossh 以在出现网络问题时保持隧道活动。
autossh -M 20000 -L 3300:192.168.2.101:3306 -R 3000:192.168.1.3:3000 [email protected] -p 80
但是如果我需要重新启动本地主机怎么办？那我如何自动重新连接隧道？
我在尝试升级 Mono 时遇到了一些问题
我已经添加到sources.list deb http://badgerports.org lucid main
尝试升级，似乎运行良好，但我明白了
mono -V
Mono JIT compiler version 2.4 (tarball Fri Oct 2 12:47:18 CEST 2009)

再做一次时，我说已经是最新版本了。
# apt-get install mono-runtime mono-2.0-devel
Reading package lists... Done

mono-runtime is already the newest version.
mono-2.0-devel is already the newest version.
The following packages were automatically installed and are no longer required:
python-rpm rpm python-urlgrabber
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
有人对如何解决此问题提出建议吗？
我试过了
apt-get purge mono-runtime mono-2.0-devel
并完成了重新安装但仍然是相同的版本
如何从终端添加 pgp 密钥？
我已将 deb http://badgerports.org lucid main 添加到 sources.list 并且当我执行sudo apt-get update我得到
W: GPG error: http://badgerports.org lucid Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C90F9CB90E1FAD0C
这是我需要添加的关键 http://badgerports.org/directhex.ppa.asc
安装 Ubuntu 10.04 后，我遇到了一些闪烁问题，所以我尝试升级驱动程序等，然后我安装了fglrx驱动程序并且闪烁消失了，但是当尝试从 1-6 访问 TTY 屏幕时，屏幕变为空白。我可以在 tty7 上重新使用 gnome。
有人对在这里尝试什么有建议吗？
