Darren Tucker's Miscellaneous Patches

Patches for stuff that doesn't fit elsewhere.

(See openntpd/patches/ for various patches to OpenNTPD.

tcptraceroute

tcptraceroute-1.4-linuxpppoe.patch
Add support for Linux PPPoE interfaces to tcptraceroute-1.4. Requires libpcap-0.7.1 or greater to work.

tcptraceroute-1.4-autoconf.patch
Add autoconf support to tcptraceroute-1.4. To use, apply this patch then run make -f Makefile.in distprep or autoreconf , then ./configure && make .

BusyBox

BusyBox is a multi-call binary suitable for use in embedded systems.

busybox-0.60.5-tftpbcast.patch. This patch (optionally) enables the use of broadcast addresses with busybox's tftp client applet via a "-c" option.

Dropbear

Dropbear is a small SSH2 server written by Matt Johnston.

dropbear-0.40pre1-hpux.patch. This patch make is work on HP-UX (tested 11.00) and fixes (what I think is) a bug in the prngd interface. The patch will also apply to the current stable version (0.39) with some fuzz.

HP-UX

resetpwtime.c Reset an account's password change time on HP-UX.
iscomsec.c Show whether or not a system is in Trusted Mode (aka Commercial Security).

The Tiny C Compiler (TCC)

tcc-0.9.20-link-order.patch Make tcc library searches behave like gcc

Test harness for Pluggable Authentication Modules (PAM)

pam-test-harness.c: a heavily-instrumented PAM test application, intended to help debug PAM/sshd problems and study the behaviour of PAM on various platforms. It also seems to be useful for testing and debugging while developing PAM modules.

You can control most aspects of the authentication, including not setting the various options (the PAM service name, PAM_TTY, PAM_RHOST, PAM_USER) and skipping the pam_authenticate call (this is common in sshd for non- password authentications, but can confuse some modules).

Here is a complete example of it in action, authenticating the user "testuser" via the sshd stack:

# ./pam-test-harness -?
usage: pam-test-harness [-?ahrt] [-s servicename] [-u user]

        -a: Skip pam_authenticate
        -h: Don't define PAM_RHOST
        -r: Don't define PAM_RUSER
        -t: Don't define PAM_TTY

# ./pam-test-harness -u testuser -s sshd

pam_faildelay module for LinuxPAM

pam_faildelay.c: Allow an admin to change the setting of LinuxPAM's pam_fail_delay from the PAM configuration file, possibly on a per-application basis.

top-3.5-aixgcc.patch

Make top 3.5 build on AIX with gcc.

gcc-3.4.0-aix421.patch

roombactl-0.1.tar.gz

A small C program to set the time and cleaning schedule on a Roomba 530 (and possibly other models) via a serial cable. Alpha quality at best since I stopped working on it once my roombas were programmed for scheduled cleaning.
