When a PPP connection is lost, no redial is attempted. There seems to be no way to configure this from the rp3 GUI. I'm using rp3-1.0.1-1
You are right. I hesitate to add every possible option to rp3-config, but perhaps redial is one of those options that should be added. In the meantime, you can work around this with echo 'PERSIST=yes' >> /etc/sysconfig/network-scripts/ifcfg-ppp0 You can also use linuxconf to make this change, although it will leave an unused chat-ppp0 file around when it does so. When linuxconf supports rp3-style wvdial configuration, it will give the option to set PERSIST=yes, just as it does now. Right now, linuxconf is the CHAT-based configuration fall-back tool for when rp3 doesn't work.
Persistant redial has been added as an option for the next release of rp3.
The latest test release at ftp://people.redhat.com/johnsonm/rp3/rp3-1.0.3-1.i386.rpm has added a persistance option. Feel free to try it out.
The latest test release is now http://people.redhat.com/nalin/rp3-1.0.7-3.i386.rpm, which fixes a few more problems.
We've released 6.2, which incorporates all known bug fixes to date. The package can be found in ftp://ftp.redhat.com/pub/redhat/redhat-6.2/i386/RedHat/RPMS/.
