Question

之前我使用ubuntu 12.04用于我的项目目的。当我使用12.04时，我曾经通过Openssh服务器结账来源，我可以查看来源。

现在我迁移到Ubuntu 16.04。现在我试图通过openssh从同一个svn查看它没有发生我收到跟踪错误

svn: E170013: Unable to connect to a repository at URL 'svn+ssh://XXXXX@YYYY.ZZZ.com/repos/'
svn: E210002: To better debug SSH connection problems, remove the -q option from 'ssh' in the [tunnels] section of your Subversion configuration file.
svn: E210002: Network connection closed unexpectedly

然后我尝试调试我得到了以下日志

任何人都可以帮我解决这个问题。

Answer 1

将14.04升级到16.04之后出现了同样的问题。

在此处找到解决方案：http://www.joho.se/2016/05/13/ssh-keys-are-no-longer-working-after-upgrading-to-ubuntu-16-04-lts-help/

错误在于：

debug1: Skipping ssh-dss key /home/chinniah/keys/chinniah.pri - not in PubkeyAcceptedKeyTypes

临时解决方法是将此行添加到您的home / yourusername / .ssh / config文件中。

PubkeyAcceptedKeyTypes=+ssh-dss

现在重启ssh：

sudo service ssh restart

问题在于ssh密钥文件。默认情况下，OpenSSH 7不允许使用ssh-dss键。这篇文章我发现了为什么：https://security.stackexchange.com/questions/112802/why-openssh-deprecated-dsa-keys

Answer 2

SVN连接问题

svn：E170013：无法连接到URL'svn：// Ip / repo'上的存储库 svn：E000113：无法连接到主机'

解决方案：

请检查您的防火墙

在防火墙中添加svn端口并重新加载

firewall-cmd --permanent --zone = public --add-port = 3690 / tcp 防火墙-cmd-重新加载

Answer 3

我遇到的主要问题与主要答复中提到的问题相同，但由于经过多次尝试，我的IP被阻止，这一事实使情况更加复杂。到我开始将-v标志添加到ssh时，我还没有获得任何信息。通过使用其他连接，我最终能够登录到服务器。然后，我从/etc/hosts.deny（或您的监视软件将它们存储为/usr/share/denyhosts/data的任何位置）中删除了IP。

在我的特殊情况下，我通过添加默认情况下ssh接受的pub / priv键类型来解决此问题。

svn：E170013：无法连接到URL上的存储库
