I just upgraded from Yosemite to El Captain but I can't connect Dell SonicWALL NetExtender version 7.5.757. I give this log message:
[general error 463] ERROR: Pppd is not setuid-root and the invoking user is not root. (3)
[general fatal 463] Please delete and reinstall NetExtender, or run chmod u+s /usr/sbin/pppd an administrator.
then I tried delete and reinstall NetExtender but not working. After I tried sudo chmod u+s /usr/sbin/pppd on terminal but I give this massage:
chmod: Unable to change file mode on /usr/sbin/pppd: Operation not permitted

Dell SonicWall NextExtender is not compatible with Mac El Captain. There is a software which enables this you can download SonicWALL Mobile Connect, which is released by SonicWALL, from below link: https://itunes.apple.com/us/app/sonicwall-mobile-connect/id822514576?mt=12
