vgetty & ppp

• Messages sorted by:[ date ][ thread ][ subject ][ author ]

On my Linux Redhat 5.1., vgetty is running on /dev/ttyS1, when I'm doing
a PPP connection with my ISP, just after I got @IP vgetty down the line.

Why ?
I give you 2 log extracts :

  1. /var/log/vgetty.ttyS1
  2. /var/log/messages
