linux - Ubuntu 14 和 Linux Mint 17 上的隧道问题

Question

我从程序管理器安装了 stunnel4。当我尝试在 Ubuntu 14 或 Linux Mint 17 上运行 stunnel 时，我收到以下消息。我在 CentOS6.5 和 MacOS X Mavericks 上工作。不确定接下来要尝试什么。重建 openssl 是一团糟，如果这甚至是问题的话。

idf@idf-ZBOX-ID42-BE ~ $ sudo stunnel
Clients allowed=500
stunnel 4.53 on x86_64-pc-linux-gnu platform
Compiled with OpenSSL 1.0.1e 11 Feb 2013

Update OpenSSL shared libraries or rebuild stunnel

Section stunnel: SSL server needs a certificate

idf@idf-ZBOX-ID42-BE ~ $ 

我的配置文件如下所示:

idf@idf-ZBOX-ID42-BE ~ $ more /etc/stunnel/stunnel.conf 
;Example stunnel configuration file by Michal Trojnara 2002-2006
; Some options used here may not be adequate for your particular configuration

; Certificate/key is needed in server mode and optional in client mode
; The default certificate is provided only for testing and should not
; be used in a production environment
;cert = stunnel.pem
;key = stunnel.pem
cert = /home/idf/Downloads/cert.pem
key  = /home/idf/Downloads/key.pem
fips = no
libwrap=no
;
;Protocol version (all, SSLv2, SSLv3, TLSv1)
;sslVersion = all
sslVersion = all 
ciphers = ALL

;
; Some security enhancements for UNIX systems - comment them out on Win32
chroot = /var/run/stunnel4/
setuid = stunnel4 
setgid = stunnel4 
; PID is created inside the chroot jail
pid = /home/idf/stunnel.pid


; Some performance tunings
socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1
compression = zlib

; Workaround for Eudora bug
options = DONT_INSERT_EMPTY_FRAGMENTS

; Authentication stuff
;verify = 2
; Don't forget to c_rehash CApath
;CApath = certs
; It's often easier to use CAfile
;CAfile = cacerts.pem
; Don't forget to c_rehash CRLpath
;CRLpath = crls
; Alternatively you can use CRLfile
;CRLfile = crls.pem

; Some debugging stuff useful for troubleshooting
debug = 7
output = /var/log/stunnel/stunnel.log

; Use it for client mode
client = yes

; Service-level configuration

accept = 127.0.0.1:9099

idf@idf-ZBOX-ID42-BE ~ $

如果我卸载存储库中的 stunnel 并将其替换为这个:

https://launchpad.net/ubuntu/utopic/amd64/stunnel4/3:5.01-3

即使我禁用压缩，我仍然可以得到。我不明白为什么它告诉我“服务 [stunnel]:SSL 服务器需要证书”，因为我试图仅在客户端模式下使用它。另外，另一端不需要证书。

前几天我刚刚通过了这个。

你想要 stunnel4_5.01-3_amd64.deb - 你必须下载它 - 还没有在 repo 中。我相信有人让它与 4.53 一起工作，但我没有成功。

https://launchpad.net/ubuntu/utopic/amd64/stunnel4/3:5.01-3

openssl 1.0.1f 和 libssl.1.0.0 以及 libssl.1.0.0:i386 1.0.1f(它们是当前版本)很好。但请从您的开始输出中注意这一点:

使用 OpenSSL 1.0.1e 2013 年 2 月 11 日编译2014 年 1 月 6 日使用 OpenSSL 1.0.1f 运行

我认为如上所述更新 stunnel 将为您排序。

你需要做的另一件事是在你的 stunnel.conf 中关闭压缩——我尝试过的不同类型的压缩目前都不起作用。希望这是暂时的。
