Uncheck the flag in Kppp that sets the hostname after a connection ('Setup' - 'Edit' - 'IP').

The telnet package now consists of two packages: 'telnet', which contains the client, and 'telnet-server'. To telnet to your machine, you need both.

Get Fortify.

* [-> 6.1/5] "metamail: can't open temporary file!"

Create a directory called 'tmp' in your home directory (mkdir -p tmp) and run the program again.

* [-> 7.1] Signal 11 Errors

This seems to hit a lot of you. Regretably diagnosis is especially hard for this one. According to the SIG11 FAQ, possible sources are:

  • Wrong memory/cache speed settings in BIOS. Increase number of waitstates.
  • Bad memory chips. If you have more than one module, try removing one.
  • 30-72 pin converters.
  • 'hidden refresh' option in BIOS is turned on. Turn it off.
  • Stupid IDE drives. Some drives cannot handle the "irq_unmasking" option. Fix unknown.
  • Badly terminated SCSI chains. Check termination, cables.
  • Bad processors. Especially some K6 seem to have a design bug.
  • Overclocking by default. Try to lower the setting for processor clock rate.
  • Power management, especially on notebooks. Try to turn it off in your book's BIOS.
  • Dust build-up. Might lead to weak shorts and bad thermal flow. Well, clean your computer ;-).

For more advice and information , read the SIG11 FAQ.
So why doesn't this happen with Windows®? This is because GNU/Linux makes much more use of hardware-specific features and therefore reacts much more sensitive to flaky parts.

* [= 7.0] Missing Pixmaps In KDE

(by Brett Jones, edited)

It seems the kdelib rpm does not install fully. Most of it makes it onto the hdd (enough to run kde) but it does not finish, and does not register in the rpm database.

Running rpm -Uvh on the kdelibs rpm (on your Mandrake CD) installs it completely and the missing pixmaps on KFM (and other apps) show up as they should.

(NOTE: I've received reports that this doesn't solve the problem for some users. Regrettably none of those who reported were willing to cooperate in trying to solve this issue...)

T.Rashid adds this (edited):
the error message reports a conflict with another rpm (kcmclock-0.1-1.rpm).
what you have to do is remove the other rpm using the usual rpm -e --nodeps and reinstall the kdelibs rpm and the removed one restart KDE and HEY! your pixmaps are there!

(Would somebody please report if this works?)

Eric Dexter wants to help you, too (edited):
FIRST: rm -rf /usr/share/doc/HTML THEN: rpm -Uvh [the KDELIBS rpm on your CD]

Anyone yet another idea? ;-)

* [-> 6.1/5] "Invalid option `preferred-stack-boundary=2"

(by Axalon Bloodstone, edited)

Run

perl -p -i -e 's/-malign-functions=2//g' /usr/src/linux/Makefile /usr/src/linux/arch/i386/Makefile

It's a bad cc1-flag.
