<div dir="ltr">Hi again,<br><br>Thank you for your prompt response. Are you at the Technion now? I will be at the SSDL lab in about 30 mins.<br><br>I understand the process in general, but I would like your help in creating a script and a HOWTO.<br>
<br>I tried to create a VPN "dialer" but it failed to authenticate. Another problem is the fact that the password consists of a 4d igit pre-shared secret and a 6 digit OTP...<br><br>If you are at the Technion, please look me up at the SSDL lab during the day, or even better - give me a call @ 054-3056707.<br>

i never connected to technion using VPN , i did it for my isp barak-013<br>
if you could send me identification or a link about the post you saw<br>
that would be helpful<br>
i also didn't use any gui for making the connection .<br>
but i would be glad to offer any help i can .<br>
<br>
for making the connection you first need to verify the infrastructure<br>
, mine was hot cable modem and my nic got connected to it via dhcp ,<br>
'ifconfig' and 'route' should show eth0 up with an ip<br>
<br>
vpn is done by pppd and pptp software which require kernel support for<br>
ppp , usually if you are not compiling a custom kernel and using<br>
kernel provided by your distribution then you don't need to worry<br>
about kernel support .<br>
<br>
what pppd does is to dial to isp ( pptp | l2tp ) server and provide<br>
authentication , so the parameters are 1) isp server ip 2) username +<br>
password .<br>
after pppd establishes authentication it brings the vpn tunnel up<br>
which is a tunnel between your pc and the isp and in order to make<br>
that tunnel it needs the pptp software .<br>
pptp can be installed easily from source package and can also be<br>
provided via your distribution .<br>
the configuration files reside in /etc/ppp , the way i configure it is<br>
to put my username and password in pap-sercrets and create peer/013vpn<br>
which describe for pppd how to bring the vpn tunnel up an that is by<br>
calling pptp , when i get back home i can send you these files to see<br>
the syntax .<br>
<br>
after pppd finishes and the tunnel is up , you need to use the 'route'<br>
command to make<br>
your kernel route your network connection via the vpn tunnel ( i don't<br>
understand this part well ) before pppd's work your connection is<br>
routed to your dhcp server ( hot/bezeq .. ) and you need to replace<br>
that with a line for the remote address of the vpn tunnel<br>
i use /etc/ppp/peers/013vpn inorder to ask pppd to use a log file<br>
which shows the remote ip of the tunnel , but there must be a better<br>
way to do that .<br>
<br>
you also need to make sure that /etc/resolve.conf has the dns<br>
nameserver of your vpn tunnel , i also user .../013vpn to tell pppd to<br>
create that file and update /etc/resolve.conf<br>
