ssh - gerrit 到 github 复制 : jsch issues

Question

尝试设置从 gerrit 到我的 github 存储库的复制。获取此堆栈跟踪:

[2011-09-20 00:11:58,470] ERROR com.google.gerrit.server.git.PushReplication : Cannot replicate to git@github.com:myuser/myrepo.git

我的配置文件如下:

复制配置:

[remote "github"]
url = git@github.com:myuser/${name}.git
push = +refs/heads/*:refs/heads/*
push = +refs/tags/*:refs/tags/*
timeout = 5
replicationDelay = 0
authGroup = Administrators

安全配置:

[database]
    password = secret
[ssh]
    file = /home/gerrit2/.ssh/config

.ssh/配置:

Host github.com:
  IdentityFile ~/.ssh/id_rsa
  PreferredAuthentications publickey

我试着运行

ssh -i etc/ssh_host_dsa_key git@github.com
ssh -i etc/ssh_host_rsa_key git@github.com
ssh -i ~/.ssh/id_rsa git@github.com
ssh -i ~/.ssh/id_dsa  git@github.com

并且能够“点击” github，因此可以导入 key ，不确定问题是什么，
任何建议表示赞赏。

作为异常的名称SocketTimeoutException说(及其 documentation details):

Signals that a timeout has occurred on a socket read or accept.

查看 documentation of Gerrit's replication.config :

remote.<name>.timeout

Number of seconds to wait for a network read or write to complete before giving up and declaring the remote side is not responding. If 0, there is no timeout, and the push client waits indefinitely.

A timeout should be large enough to mostly transfer the objects to the other side. 1 second may be too small for larger projects, especially over a WAN link, while 10-30 seconds is a much more reasonable timeout value.

Defaults to 0 seconds, wait indefinitely.

您的值是 5 秒，您可以尝试使用更大的值。

(问题仅与 JSch 间接相关 - JSch 的 Session.connect(int) 将简单地获取超时参数并将其传递给它创建的 Socket。我应该记录此超时的单位为 reminds me 的 JSch - 秒或毫秒。 )
