Configuring the Windows Firewall for Symantec AntiVirus on an XP System
When Service Pack 2 is installed on a Windows XP system, the Windows
Firewall is automatically activated on that system. The firewall
can prevent a Symantec Antivirus Server, e.g. a system functioning
as the antivirus server for Symantec AntiVirus Corporate Edition 8.0,
from managing the Windows XP client. You will need to add an exception
to the firewall settings on the client system to open UDP port
2967 access from the antivirus server.

CDE Desktop Not Restored After Shutdown
I was switching back and forth between a Sun Solaris SPARC workstation
and a Knoppix Linux LiveCD system and placed the keyboard for the Sun
system against the side of the desk when I switched to the Linux system.
I then inadvertently knocked over the Sun keyboard. It fell face down and
the keyboard button that will power off the Sun must have been depressed,
since it shut itself down. After it shut down, I hit the button again to
power it up, hoping I would find my desktop just as it was when the system
shut down.
When the system, which is running Solaris 2.7, powered back on, I got my Common
Desktop Environment (CDE) login prompt informing me I needed to unlock the
screen. I logged into the regular user account I had been using only to find a
white desktop with none of the many windows that had been open previously
visible. I had a lot of information I didn't want to lose, so I tried pinging
the system from another system, which worked. I was also able to establish an
SSH connection to the Sun system
from the Linux PC.
So I went back to the Sun's console and tried some key combinations to see if I
could get to any of the windows I had open previously. I found that just
as on a Windows-based PC, I could hit the Alt and tab keys simultaneously
to cycle through the open windows. When I did so, I saw a small icon for each
window, which I could then open fully by hitting Alt-space and then choosing
"Maximize" from the menu that appeared (Alt-F10 will also maximize the
window). I was then able to save information in windows I had open
previously.
Since I had a lot of windows open and I really wanted to just pick up from
where I had been when the system powered down, I searched for an alternative
means of restoring the CDE
. In the
Solaris
7 3/99 Online Release Notes (SUNWrdm), I found a secton titled
"SPARC only: restore from sys-suspend Sometimes Does Not Restore CDE (4174133)",
which described the problem I was experiencing, i.e. a white screen appearing
after a system was restored from a sys-suspend. The information provided
in that section is included below:
SPARC only: restore from sys-suspend Sometimes Does
Not Restore CDE (4174133)
sys-suspend(1M) may hang and not refresh the screen on some
slow systems. After a system is resumed, Screen Lock is in effect by
default. This problem occurs after you enter a user password. A white
screen is displayed instead of a Common Desktop Environment (CDE) screen.
Although you can gain access to the system remotely, you cannot enter
anything because the screen is still locked. If this problem occurs, you
can recover the CDE session by remotely logging on the system as superuser
and then killing the sys-suspend process.
Workaround: If this problem has occurred as a result
of executing autoshutdown, use the dtpower(1M)
application to disable autoshutdown. The problem does not
occur if you execute sys-suspend without the Screen Lock
option.
Refer to "Disabling
the Screen Lock" in Using Power ManagementSolaris 7
Reference Manual Collection for a description on how to disable the
Screen Lock for sys-suspend invoked by the keyboard's power
key. To disable the Screen Lock for the sys-suspend command
that is invoked from the CDE Workspace Menu:
-
Become superuser.
-
Create the following dtaction file
/etc/dt/appconfig/types/locale/sunOW.dt. The
locale is the name of the language option that is selected when
you start CDE.
-
Copy the ACTION SDTsuspend { ... } definition from
/usr/dt/appconfig/types/locale/sunOW.dt to
/etc/dt/appconfig/types/locale/sunOW.dt.
-
Add the -x flag to sys-suspend command in the
/etc/dt/appconfig/types/locale/sunOW.dt file.
-
Exit the CDE session and log in again.
I didn't follow those instructions, but they provided me with the clue
I needed to get my desktop to reappear with all of its windows visible
again. From the terminal window I had open where I had established the SSH
session, I became root and then searched for the sys-suspend process.
When I found it I tried to kill it with kill -HUP, but that
didn't kill it, though kill -9 did produce a prompt to
suspend, shutdown, or cancel on the screen of the Sun workstation.
# ps -ef | grep suspend
root 12233 20298 0 17:15:39 pts/12 0:00 grep suspend
root 20868 20867 0 16:18:40 ? 0:13 /usr/openwin/bin/sys-suspend
# kill -HUP 20868
# ps -ef | grep suspend
root 12452 20298 0 17:16:16 pts/12 0:00 grep suspend
root 20868 20867 0 16:18:40 ? 0:13 /usr/openwin/bin/sys-suspend
# kill -9 20868
When I used the kill -9 followed by the PID, a window popped up on the console with
three options: suspend, shutdown, or cancel. I chose "cancel" and the
desktop reappeared with all of my windows just as I had left them.
