[i=s] 本帖最後由 ckleea 於 2015-5-15 09:35 編輯 [/i]通過雯雯介紹
成功將Openconnect VPN server 放在 Debian Wheezy X86 server
安排方法如下
[size=5][color=Red]1. 系統準備[/color][/size][code]
# need to have newer gnutls req backports
echo "deb http://ftp.debian.org/debian wheezy-backports main contrib non-free" | tee -a /etc/apt/sources.list
aptitude update
aptitude -t wheezy-backports -y install libgnutls28-dev
aptitude -y install libgmp3-dev m4 gcc pkg-config make gnutls-bin libreadline-dev
aptitude -y install libpam0g-dev libwrap0-dev liblz4-dev libseccomp-dev libkrb5-dev libprotobuf-c0-dev libnl-route-3-dev libreadline-dev libtalloc-dev libopts25-dev libwrap0-dev
[/code][size=5][color=Red]2. 下載OpenConnect VPN Server 源碼 # as of today, latest=0.10.4[/color][/size][code]# Get OCServ
mkdir /usr/src/ocserv
cd /usr/src/ocserv
wget ftp://ftp.infradead.org/pub/ocserv/ocserv-0.10.4.tar.xz
tar xvf ocserv-0.10.4.tar.xz
cd ocserv-0.10.4
./configure --prefix=/usr --sysconfdir=/etc
make
make install
mkdir /etc/ocserv
cp doc/sample.config /etc/ocserv/
mv /etc/ocserv/sample.config /etc/ocserv/ocserv.conf[/code][size=5][color=Red]3. 準備 系統 certificate，如有有效的certificate更好[/color][/size][code]## Generate your self-signed certificate for Ocserv use
## change the value in CN and organization based on your choice
## create two files for certificate generation
1. ca.tmpl
cn = "VPN CA"
organization = "Big Corp"
serial = 1
expiration_days = 9999
ca
signing_key
cert_signing_key
crl_signing_key
2. server.tmpl
cn = "www.example.com"
organization = "MyCompany"
expiration_days = 9999
signing_key
encryption_key
tls_www_server
certtool --generate-privkey --outfile ca-key.pem
certtool --generate-self-signed --load-privkey ca-key.pem --template ca.tmpl --outfile ca-cert.pem
certtool --generate-privkey --outfile server-key.pem
certtool --generate-certificate --load-privkey server-key.pem --load-ca-certificate ca-cert.pem --load-ca-privkey ca-key.pem --template server.tmpl --outfile server-cert.pem
cp server-cert.pem /etc/ssl/certs/
cp server-key.pem /etc/ssl/private/[/code][size=5][color=Red]4. 修改設定檔，只需要修改下面的行列[/color][/size][code]## config your own /etc/ocserv/ocserv.conf
## change the setting as below

## change the port 443 to the port you choose
## change the ip address 10.10.0.0 to the ip address you choose

[/code][size=5][color=Red]8.最後重啟系統[/color][/size][code]## reboot the machine and openconnect server should work[/code] 我的介紹不是自動安裝scripts
需要 copy and paste 部分係 command line 行
部分需要 editor 修改 Reference:
[url]http://blog.ltns.info/linux/vps_debian_ocserv_support_anyconnect/[/url] An update
0.10.4 ocserv also works 更新了帖的instructions If you use rsyslog to log the auth messages from ocserv
add the following lines into /etc/rsyslog.conf
# log messages from ocserv into /var/log/ocserv.log
if $programname == 'ocserv' then /var/log/ocserv.log
It will log the message into /var/log/ocserv.log 請問可唔可以教下整CA 果一part, 我覺得好難明, 唔知自己做緊什麼 ck这个帖子不错！有非常好的参考价值。
