denyhosts 不断添加我的 IP [英] denyhosts keeps adding back my IP

问题描述

我正在尝试解除阻止我进行一些测试的 IP.我是按照网上的教程来的:

I am trying to unblock an IP from which I was doing some tests. I have followed the tutorials on the net:

$ sudo /etc/init.d/denyhosts stop
$ sudo vim /etc/deny.hosts
[remove the last line where I can see my IP to clear]
$ cd /var/lib/denyhosts/
$ sudo vim *
[remove any occurences of my IP to clear]
$ sudo /etc/init.d/denyhosts start

此时我的 IP 又出现在/etc/deny.hosts 中.我也试过:

At this moment my IP appears back into /etc/deny.hosts. I tried also:

$ cd /var/lib/denyhosts/
$ echo '123.456.789.122' >> /var/lib/denyhosts/allowed-hosts

我也试过:

$ echo 'my.ip.to.clear' >> /etc/hosts.allow

不幸的是，hosts.deny 总是优先，拒绝 ssh 连接，从日志文件可以看出:

Unfortunately the hosts.deny always takes precedence, and refuse ssh connection, as can be seen from the log file:

2 月 10 日 10:06:24 ks123456 sshd[22875]:拒绝连接123.456.789.122 (123.456.789.122)

Feb 10 10:06:24 ks123456 sshd[22875]: refused connect from 123.456.789.122 (123.456.789.122)

参考:debian/6.0.4，denyhosts 2.6-10

ref: debian/6.0.4, denyhosts 2.6-10

推荐答案

可以在此处找到删除 denyhosts 条目的说明:http://www.cyberciti.biz/faq/linux-unix-delete-remove-ip-address-that-denyhosts-blocked/.在 Ubuntu 中，denyhosts 数据文件位于 /var/lib/denyhosts.

The instructions to remove an entry for denyhosts can be found here: http://www.cyberciti.biz/faq/linux-unix-delete-remove-ip-address-that-denyhosts-blocked/. In Ubuntu the denyhosts data files are located at /var/lib/denyhosts.

1. 确保拒绝主机中没有代表您 IP 地址的域名的条目.
2. 从/etc/deny.hosts(对于 Ubuntu 为/etc/hosts.deny)中删除所有出现的 IP 地址和域名后，如果您仍然无法登录，请检查身份验证日志，通常在:/var/log/auth.log它可能会为您提供有关问题所在的线索.
3. 如果您在服务器和客户端上都运行 linux，您可能需要使用 ssh-copy-id，这样您就不需要密码登录，以防止因使用错误密码太多次而将自己锁定未来.

1. Make sure there are not entries that represent the domain name for your IP address in denyhosts.
2. After removing all occurrences of your IP address, and domain name from /etc/deny.hosts (/etc/hosts.deny for Ubuntu) if you are still unable to log in, check the authentication log usually in: /var/log/auth.log It may give you clues to what your problem is.
3. If you are running linux on both the server and client, you may want to use ssh-copy-id so that you don't need a password to login to prevent locking yourself out by using the wrong password too many times in the future.

我自己遇到了问题，因为我使用 sftp 在 KDE 上的 Dolphin 中保存了一个位置到我的服务器.Dolphin 使用您当前的用户名尝试登录，从而将我的 IP 添加到 hosts.deny 文件中.

I had problems myself because I had a location saved in Dolphin on KDE to my sever using sftp. Dolphin uses your current username to try logging in which was getting my IP added to the hosts.deny file.
