Question

我一直在尝试使用RCurl和SFTP连接并列出文件。我认为，我的价值观可能在错误的地方。这是我从WinSCP获得的.NET汇编代码C＃（我正在尝试将其复制到R以获取连接）。

Protocol = Protocol.Sftp,
HostName = "sftp.website.com",
UserName = "username",
Password = "pswrd",
SshHostKeyFingerprint = "gibberish",


sessionOptions.AddRawSettings("ProxyMethod", "2");
sessionOptions.AddRawSettings("ProxyHost", "somerandom.looking.com");
sessionOptions.AddRawSettings("ProxyPort", "8080");
sessionOptions.AddRawSettings("ProxyUsername", "proxy_user");
sessionOptions.AddRawSettings("ProxyPassword", "proxy_pswrd");

我在R中尝试过的操作如下：

library(RCurl)

opts <- curlOptions(
  proxytype = 2,
  proxy         = "somerandom.looking.com",
  proxyport     = 8080,
  proxyusername = "proxy_user",
  proxypassword = "proxy_pswrd",
  ssh.private.keyfile = "gibberish"
)

url <- "sftp://username:pswrd@sftp.website.com/"

getURL(url = url, .opts = opts, dirlistonly = TRUE)

Error in function (type, msg, asError = TRUE)  : 
  Failure establishing ssh session

我遗漏了什么？价值观是否在错误的地方？

最后解决了。我不得不更改代理并添加用户名和密码。

opts <- curlOptions(
  proxy         = "http://mynewproxy/",
  proxyport     = 8080,
  proxyusername = "domain\\user", 
  proxypassword = "pwd", 
  httpproxytunnel = 1L,
  ssh.private.keyfile = "ssh-gibberish"
)

通常代理使用Windows passowrds，但我怀疑这是不同的。
