Comment on DenyHosts on FreeBSD 6.2 by Scott Spare

Great article. One note that might be of interest: in addition to your suggestions, the denyhosts faq mentions blanking out the BLOCK_SERVICE value when using auxiliary files.
http://denyhosts.sourceforge.net/faq.html#aux

Can anyone comment on why this might be?

Also, any comments on how to block ALL access from the offending hosts? This seems doable, but the tutorials and documentation seem to suggest the approach of just blocking ssh. Maybe this is to prevent a DoS to all your services at once if someone’s injecting code?

I’ve been having timing issues with vmplayer on a custom kernel. I have done EVERY possible thing I could think of when building a custom kernel for vmplayer but the time always runs really fast and the reported CPU is much slower than it actually is. I read all of vmware’s documentation and all I found is that the kernel requires the rtc and parallel port support. Using the tsc as the system timer works fine for the guest (with the exception of choppy audio) but performance suffers. I would like to be able to use the hpet. Could you possibly post your entire kernel config? btw, vmware’s documentation for linux is disgusting so I appreciate posts like this.
Thanks,
Ben

Great post and thanks!

I wish I could point it at HTTP logs for brute force attacks against my .htaccess
There are an awful lot of people trying to access my phpmyadmin alias.

That is very odd. I’ve never – at all – come across this issue with 64-bit architectures.

Did you try poking in your kernel config?

revisiting this issue… apparently this isn’t the magic bullet…

/proc$ zcat config.gz |grep CONFIG_RTC
CONFIG_RTC=y
/proc$ zcat config.gz |grep HPET
CONFIG_HPET_EMULATE_RTC=y
/proc$ dmesg | tail -2
rtc: lost some interrupts at 512Hz.
rtc: lost some interrupts at 512Hz.

Hardware is SC1435.
Linux hostname 2.6.22-3-amd64 #1 SMP Mon Nov 12 17:53:18 UTC 2007 x86_64 GNU/Linux

Any other ideas?

th3D:
Well, in my situation (With a Dell PowerEdge server), the BIOS didn’t have an option to turn off HPET. Also, why NOT use HPET?

WHY rebuild kernel when HPET usually can be turned off in BIOS? HPET isnt a requirement but rather a supplement, im sure HPET will be supported in the next major Debian release, until then Debian is still one of the best distros and i hope people dont start recompiling or change distro without taking 30 seconds to look for it in Bios first.
