I could really use some help. I have "headless" FreeBSD 5 web server
that I'd like to be able to log on to via a serial link to my lap top.
I've been using the FreeBSD Handbook as my guide, but its just not
getting me there.
Without getting too far into it, does anyone have any suggestion as to
how I might trouble shoot the system? What test can I preform to
isolate the trouble spot? If you're willing, please read on to get
more details about what I have done so far.
Thanks for your time + help
So far I've installed a couple of terminal emulators on the test PCs
(one is a Mac OsX TiBook and one is a win2k box). For emulation
software I've tried (Mac) Zterm and MacWise, (win2k) KoalaTerm.
For the serial cable I'm using a Manhattan LapLink female to female
null modem serial cable. When attaching to the TiBook, I add a KeySpan
PDA Adapter (pn# USA-19). I followed that recommendations I found
On the FreeBSD box I've edited the etc/ttys as below
root# vim /etc/ttys
# Serial terminals
# The 'dialup' keyword identifies dialin lines to login, fingerd etc.
ttyd0 "/usr/libexec/getty std.19200" vt100 on insecure
ttyd1 "/usr/libexec/getty std.19200" vt100 on insecure
ttyd2 "/usr/libexec/getty std.9600" dialup off secure
ttyd3 "/usr/libexec/getty std.9600" dialup off secure
The I checked a few things ...
root# /sbin/dmesg | grep sio
usb0: USB revision 1.0
usb1: USB revision 1.0
sio0 port 0x3f8-0x3ff irq 4 on acpi0
sio0: type 16550A
sio1 port 0x2f8-0x2ff irq 3 on acpi0
sio1: type 16550A
[sbox.net:~] root# ps -axww | grep getty

472 ?? I 0:00.00 /usr/libexec/getty std.19200 ttyd1

469 v6 Is+ 0:00.00 /usr/libexec/getty Pc ttyv6
470 v7 Is+ 0:00.00 /usr/libexec/getty Pc ttyv7
But in the end, I get nothing when I connect it all up. None of the
emulators on either platform give me a login prompt, or anything at all
for that matter.
