Hello, Unfortunately, I do not have a solution to your problem. I just wanted to pass along some information concerning PuTTY from a security news letter to which I subscribe: 04.31.4 CVE: Not Available Platform: Third Party Windows Apps Title: PuTTY Remote Buffer Overflow Description: PuTTY is a free Telnet and SSH client. It has been reported that PuTTY is subject to a pre-authentication buffer overflow that can allow malicious servers to execute code on a client machine as it attempts to negotiate connection. PuTTY 0.54 and previous versions are vulnerable. Ref: http://www.coresecurity.com/common/showdoc.php?idx=417idxseccion=10 Note that the URL may have wrapped. Regards, Stheg Stehg Thanks for the security note/update on putty! I'm using version 5.5 now. Michael __ Do you Yahoo!? Yahoo!

How to increase scrollback for FreeBSD-4.10?
Greetings: I have a FBSD-4.10 system that I log into using PuTTY (on a Win2K workstation). I am able to set PuTTY's scrollback to 1200 lines. When I'm on the 4.10 box the scrollback is about 200 lines. If possible I'd like to set the scroll back to 600 lines or so (at least). Question: How do I increase the scrollback on 4.10? Note: The video card on the 4.10 box is a Voodoo3-2000 (16 Mb) card. I searched the FBSD mail archives going back to 2003 and could not find a single reference. I also googled and could not turn up anything specific to FBSD. Hints?

That depends on the console program you're using. For an xterm(1),
the following in ~/.Xdefaults will give you 8k scrollback lines:
xterm*saveLines:8192
(Remember to run '/usr/X11R6/bin/xrdb -merge ${HOME}/.Xdefaults' out
of .xsession or .xinit so that gets set every time you log in)
For the system console, you'll need to play with the syscons(4)
history size. Modify your kernel configuration to set
options SC_HISTORY_SIZE=N
where N is the number of lines of scroll back you want (default 100).
Then build and install a new kernel in the usual way:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
There doesn't seem to be any way of achieving the same effect via
sysctl(8), which is unfortunate.
Cheers,
Matthew

Except of course, for the kbdcontrol(1) program which I am reminded
does all that sort of stuff. Changing SC_HISTORY_SIZE will let you
alter the default size of the history buffer, kbdcontrol(1) lets you
override that to whatever value you want.

Matthew

Thanks, Michael kbdcontrol Scroll Lock History While your system boots, probe messages scroll across the consoles screen so fast that you can not read them. Or when you list the contents of a large directory the same thing happens. The messages may have scrolled off your screen, but they are still in the screen buffer. You can redisplay the messages from the screen buffer. You hit the keyboard 'scroll lock' button, (IE: top row right side) and then use the keyboard up arrow button to scroll back through the screen buffer to redisplay the message lines. The 'page up' and 'page down' buttons also work to move backward and forwards through the screen buffer one full screen page at a time. Hit the 'scroll lock' button again when you are finished to return to the command line prompt. The default size of the screen buffer is to small to contain all the boot messages, so it should be increased to 200 lines. This is how you increase the size of the screen buffer. Add the -h 200 option onto the allscreens_flags= statement you already added to the /etc/rc.conf file ee /etc/rc.conf and add this statement, allscreens_flags=h 200 # -h size of scroll lock buffer in number of lines Save the changed file and reboot your system for your edit changes to take effect. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Then build and install a new kernel in the usual way:
xterm like programs allow the -sl switch lines. I've had problems with
numbers approaching 32767 but have never nailed down exactly how many
lines I can save. I safely use -sl 3 for xterm, rxvt, aterm, and
gnome-terminal.
This would be an excellent topic to include in the fortune file:

I went and tried this using this kdbcontrol command in my .cshrc: # added to increase scrollback to 1000 /usr/sbin/kbdcontrol -h 1000 This gave me 1,000 lines when I'm logged into the console however, it resulted in a Inapproriate ioctrl for device error when using xterm (xfterm4) under xfce4. So I removed the kdbcontrol from my .cshrc and used a -sl 3000 option to launch xfterm4. So launching xfterm4 -sl 3000 now does the trick!
