I went over my notes and discovered that they were not as complete as
needed to be. As a result I decided to reinstall FC3, and get a fresh start.
I first used the network configuration application to configure the
dialup. This time the modem came up as ttyS4.
I got mesage:Cannot activate network device xxxxxxxx Failed to activate
xxxxxxx with error 8
Logged on yyyyyy@localhost, I opened a terminal and entered the command
tail -f /var/log/messages, and got cannot open tail -f /var/log/messages
for reading: Permission denied
Someone suggested that I log on to a terminal as Su_-. I entered Su_- at
the command line and got: bash:Su_- command not found
Did they mean that I reboot, and enter Su_- at user name prompt?
How and where do I invoke Su_-?
It is "su -"! No underscore, "-" is an option and is the short for of
"-l" (-> man su). And on Linux it matters whether you use lower or
capital letters.
I understand that it is not wise to make changes to wvdial logged on as
root!
I then entered wvdial and got
-->WvDial: Internet dialer version 1.54.0
-->Warning: section[Dialer Defaults] does not exist in wvdial.conf.
-->cannot open /dev/modem: Device or resource busy
-->cannot open /dev/modem: Device or resource busy
-->cannot open /dev/modem: Device or resource busy
You need to create a symlink: ln -s /dev/ttySX /dev/modem (where X is
the number of the serial device).
I logged out, and then tried to log in, entering Su_- at Username
That did not work, so I logged in as root.
I then entereed wvdial, and got:
-->WvDial: Internet dialer version 1.54.0
-->Warning: section[Dialer Defaults] does not exist in wvdial.conf.
-->cannot open /dev/modem: No such file or directory
-->cannot open /dev/modem: No such file or directory
-->cannot open /dev/modem: No such file or directory
I then entered: /etc/wvdial.conf , and got:
bash: /etc/wvdial.conf: Permission denied
/etc/wvdial.conf
How can I execute the command /etc/wvdial.conf with out getting
permission denied? I am assuming that since that I am logged on as
root@localhost that I would have the permission.
vim /etc/wvdial.conf
It is a configuration file you need to open with an editor. It is
nothing to execute.
Is there a way to log onto a terminal as super user, while I am logged
on as xxxx@localhost?
See above.
