我今天早上创建了一个新的 OpenVPN 安装。我的测试用户工作正常，一切正常。现在我想创建额外的用户，但是当我运行此命令时：
C:\Documents and Settings\User>"C:\Program Files\OpenVPN\easy-rsa\build-key" newuser
系统返回的信息如下：
C:\Documents and Settings\User
req [options] <infile >outfile
where options are
-inform arg input format - DER or PEM
-outform arg output format - DER or PEM
-in arg input file
-out arg output file
-text text form of request
-pubkey output public key
-noout do not output REQ
-verify verify signature on REQ
-modulus RSA modulus
-nodes don't encrypt the output key
-engine e use engine e, possibly a hardware device
-subject output the request's subject
-passin private key password source
-key file use the private key contained in file
-keyform arg key file format
-keyout arg file to send the key to
-rand file;file;...
load the file (or the files in the directory) into
the random number generator
-newkey rsa:bits generate a new RSA key of 'bits' in size
-newkey dsa:file generate a new DSA key, parameters taken from CA in 'file'
-newkey ec:file generate a new EC key, parameters taken from CA in 'file'
-[digest] Digest to sign with (md5, sha1, md2, mdc2, md4)
-config file request template file.
-subj arg set or modify request subject
-multivalue-rdn enable support for multivalued RDNs
-new new request.
-batch do not ask anything during request generation
-x509 output a x509 structure instead of a cert. req.
-days number of days a certificate generated by -x509 is valid for.
-set_serial serial number to use for a certificate generated by -x509.
-newhdr output "NEW" in the header lines
-asn1-kludge Output the 'request' in a format that is wrong but some CA's
have been reported as requiring
-extensions .. specify certificate extension section (override value in config
file)
-reqexts .. specify request extension section (override value in config file
)
-utf8 input characters are UTF8 (default ASCII)
-nameopt arg - various certificate name options
-reqopt arg - various request text options
unknown option -config
usage: ca args
-verbose - Talk a lot while doing things
-config file - A config file
-name arg - The particular CA definition to use
-gencrl - Generate a new CRL
-crldays days - Days is when the next CRL is due
-crlhours hours - Hours is when the next CRL is due
-startdate YYMMDDHHMMSSZ - certificate validity notBefore
-enddate YYMMDDHHMMSSZ - certificate validity notAfter (overrides -days)
-days arg - number of days to certify the certificate for
-md arg - md to use, one of md2, md5, sha or sha1
-policy arg - The CA 'policy' to support
-keyfile arg - private key file
-keyform arg - private key file format (PEM or ENGINE)
-key arg - key to decode the private key if it is encrypted
-cert file - The CA certificate
-selfsign - sign a certificate with the key associated with it
-in file - The input PEM encoded certificate request(s)
-out file - Where to put the output file(s)
-outdir dir - Where to put output certificates
-infiles .... - The last argument, requests to process
-spkac file - File contains DN and signed public key and challenge
-ss_cert file - File contains a self signed cert to sign
-preserveDN - Don't re-order the DN
-noemailDN - Don't add the EMAIL field into certificate' subject
-batch - Don't ask questions
-msie_hack - msie modifications to handle all those universal strings
-revoke file - Revoke a certificate (given in file)
-subj arg - Use arg instead of request's subject
-utf8 - input characters are UTF8 (default ASCII)
-multivalue-rdn - enable support for multivalued RDNs
-extensions .. - Extension section (override value in config file)
-extfile file - Configuration file with X509v3 extensions to add
-crlexts .. - CRL extension section (override value in config file)
-engine e - use engine e, possibly a hardware device.
-status serial - Shows certificate status given the serial number
-updatedb - Updates db for expired certificates
Could Not Find C:\*.old
有办法解决这个问题吗？（除了重新安装应用程序吗？）
我有一个理论，它要求我事先运行一些先前的命令，但如果是这样，我不确定哪一个；我不想意外地杀死我的服务器密钥（尽管我可能误解了每个命令的用法）。
答案1
easy-rsa 脚本依赖于一些环境变量，您应该事先在 中配置并获取这些变量vars.bat。假设它仍然包含正确的信息，则只需重新执行vars.bat即可继续。
答案2
确保您之前制作的 ca.crt、ca.key、01.pem、02.pem、03.pem 和 dh1024.pem 文件位于或在您的 Program Files\OpenVPN\easy-rsa\keys 文件夹中有副本。
