Stunnel和hpux：为什么会出现此错误？

埃尔巴纳

我用这些选项在hpux上编译了一个tunnel版本

./configure \
  --prefix=/opt/stunnel \
  --sbindir=/opt/stunnel/sbin \
  --mandir=/opt/stunnel/man \
  --docdir=/opt/stunnel/doc \
  --localstatedir=/var/opt/stunnel \
  --with-ssl=/usr/local \
  --disable-libwrap

构建成功，但无法启动隧道

/opt/stunnel/bin/stunnel /etc/opt/stunnel/stunnel.conf
[ ] Clients allowed=1000
[.] stunnel 5.50 on ia64-hp-hpux11.31 platform
[.] Compiled with OpenSSL 1.0.2q  20 Nov 2018
[.] Running  with OpenSSL 1.0.2k  26 Jan 2017
[.] Threading:PTHREAD Sockets:POLL,IPv6 TLS:ENGINE,FIPS,OCSP,PSK,SNI
[ ] errno: (*__errno())
[!] Invalid configuration file name "/etc/opt/stunnel/stunnel.conf"
[!] realpath: Invalid argument (22)
[ ] Deallocating section defaults

配置文件正确，因为在相同版本的linux和solaris上可以正常工作。我看到这两行：

[.] Compiled with OpenSSL 1.0.2q  20 Nov 2018
[.] Running  with OpenSSL 1.0.2k  26 Jan 2017

我有两个版本的openssl，当然不可能同时删除两个或一次，因为会破坏很多部门。我也试过换线

  --with-ssl=/usr/local \

和

  --with-ssl=/opt/openssl\

和..不起作用。同样的错误

/opt/stunnel/bin/stunnel /etc/opt/stunnel/stunnel.conf

这是文件conf。

#server

根据HP-UX 11.31手册页，来自调用的Invalid argument错误（EINVAL）realpath(3X)表示指向要解析的路径名或指向已解析名称的缓冲区的指针为NULL。

这可能是检查配置文件名有效性的代码部分中的某种指针处理错误。这也可能会解释前面的Invalid configuration file name错误消息。
