Q: The ordb.org test probe claims that my Qmail server is an open relay. I've got a valid "rcpthosts" file and I'm setting the RELAYCLIENT environment variable as per the qmail instructions. What's wrong?
A: Do you have a "percenthack" file in the qmail control directory? Make sure no line in "percenthack" also appears in "envnoathost" (or "me" if "envnoathost" doesn't exist). Type 'man qmail-send' for more information.
Q: I have a SonicWall SOHO Firewall and RealPlayer isn't working. How do I fix it?
A: Get the latest firmware from SonicWall. The RealPlayer bug was fixed in Release 5.1.7.0.
Q: I have PacBell (SBC) DSL service and an old Alcatel 1000. It quit working, and SBC tech support isn't very helpful. What should I do?
A: Call (877) 722-3755, then press 1 1 4. Ask them to perform a "rip and rebuild" on your line, and be sure to configure it for "ATM" rather than "Universal." If that doesn't help, threaten to cancel service and you'll be transferred to the "save the sale" department for a free visit from a technician.
Q: I've checked the "Disable Script Debugging" option in IE5. Unfortunately, something is unchecking it. What's up?
A: Do you have Visual InterDev installed? Even if you don't remember installing Visual InterDev, it may be on your system. It's included as part of Visual Studio. Go to:
Start -> Programs -> Microsoft Visual Studio 6.0 -> InterDev
and follow the instructions in Microsoft's Knowledge Base Article.
Q: When I type "make install" in the gdbm top-level directory, I get the message "can't open libgdbm.so.2.0.0: No such file or directory." How can I fix this?
Look for this in the generated Makefile:
install: libgdbm.la gdbm.h gdbm.info
$(srcdir)/mkinstalldirs $(libdir) $(includedir) $(man3dir) $(infodir)
$(LIBTOOL) install -c libgdbm.la $(libdir)/libgdbm.la
Change the command literal "install" in the last line to the variable "$(INSTALL_PROGRAM)," like this:
$(LIBTOOL) $(INSTALL_PROGRAM) -c libgdbm.la $(libdir)/libgdbm.la

Q: I've managed to turn off the little tool on my KDE taskbar that switches between virtual desktops. If I right-click on the taskbar to make changes, I can't seem to find any option to re-enable the tool.
A: That's because it has the unobvious name "Pager." In KDE, right-click on the taskbar and select Add -> Applet -> Pager. "Pager" implies a one-screen-at-a-time file display utility like 'less' or 'more.'
Q: I'm running VMWare 3 under Linux. Windows 2000 is running in the virtual machine. When I attempt to switch to full-screen mode, VMWare just continues running in a window.
A: Try disabling the message window that pops up when you press the "Full Screen" button. It worked for me.
Q: My Asus P4S8X's (SiS 648/963) built-in Ethernet adapter doesn't work under Linux. What now?
A: Use kernel 2.4.20 or later.
Q: I recently installed Fedora Core 2. I am using an LCD display. When using KDE, I cannot turn "sub-pixel hinting" off in the Fonts control panel. Even if I uncheck it, the fonts still look terrible. What can I do?
A: Sub-pixel font rendering for LCDs, such as "ClearType," is an awful invention that attempts to marginally increase the apparent spatial resolution of text at the expense of nasty color fringes reminiscent of a CRT with badly misajusted convergence.
Sadly, KDE won't take no for an answer -- if an LCD display is detected, then sub-pixel "hinting" is enabled whether you check it or not. To turn it off for real, add the following to ~/.fonts.conf:
<match target="font">
<edit name="rgba" mode="assign">
<const>
none
</const>
</edit>
</match>
