I'm trying to setup a VPN connection on OpenSUSE Leap 42.2, with the following command:me@linux-box:~> sudo pptpsetup --create TUNNEL --server 172.16.100.2 --username 444182 --password 255553 --startBut I'm receiving the following error message: Using interface ppp0Connect: ppp0 <--> /dev/pts/5anon warn[open_inetsock:pptp_callmgr.c:329]: connect: Connection refusedanon fatal[callmgr_main:pptp_callmgr.c:127]: Could not open control connection to 172.16.100.2anon fatal[open_callmgr:pptp.c:479]: Call manager exited with error 256Script pptp 172.16.100.2 --nolaunchpppd finished (pid 17988), status = 0x1Modem hangupConnection terminated.Also, when trying to start the VPN with:pppd call TUNNEL debug nodetachI receive the same error message. Also, when I turn off my firewall, I receive the same error message. I wonder if anybody knows how to resolve it.
Start a VPN connection with PPTP protocol on command line
opensuse;vpn;pptp
Actually, I realized that the PPTP was disabled on MikroTik v6.25, i.e. IP address 172.16.100.2, that's why I couldn't connect to the VPN server. After enabling the PPTP on MikroTik, I'm able to connect to the server like this: me@linux-box:~> sudo pppd call TUNNEL debug nodetachusing channel 15Using interface ppp0Connect: ppp0 <--> /dev/pts/5sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xa905bd9b> <pcomp> <accomp>]sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xa905bd9b> <pcomp> <accomp>]sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xa905bd9b> <pcomp> <accomp>]sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xa905bd9b> <pcomp> <accomp>]sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xa905bd9b> <pcomp> <accomp>]sent [LCP ConfReq id=0x1 <asyncmap 0x0> <magic 0xa905bd9b> <pcomp> <accomp>]
