	SecuriTeam™ - KPPP Privileged File Descriptor Leak
		KPPP is "a dialer and front end for PPPd, allowing for interactive script generation and network setup".
		Typically, KPPP is installed setuid root and uses privilege separation to allow only certain functions of the PPP dialer to execute with elevated privileges.
		KPPP may be abused to gain read and write access to /etc/hosts and /etc/resolv.conf, thus giving attackers complete control over a system's domain resolution capabilities.

		The opening screen of kppp will list any available connections, and allow you to specify a Login ID and password for the connection.
		The "Dock" option states that kppp should recede into the KDE dock when it is connected.
		The "Graph" tab is useful for kppp's throughput graphing.

	Your Linux Desktop Internet Connection
		Kppp is an extremely well thought out front end to pppd that makes connection to the 'net almost trivial.
		My experience is that when you use PAP this is unnecessary, because kppp automatically passes needed args to pppd, and does all the other little tasks necessary for correct running of the daemon and connection to the ISP.
		Kppp is smart enough that it takes the dynamic address and issues a default route command to properly enable routing.

	Kppp - Wikipedia, the free encyclopedia
		kppp is a modem and internet dialer for the KDE system, whose name is an abbreviation for "KDE Point-to-Point Protocol".
		kppp is generally used to connect to an internet service provider via a modem and phone line, although it can be used in other situations where the PPP protocol is needed.
		It is a graphical frontend to the pppd daemon, designed to make it easy for non-technical users to connect to the internet from home using their KDE system.

	kppp from the command line?
		Kppp is a KDE GUI frontend for for pppd anyway.
		Or perhaps it is not possible to > have it auto connect Kppp (from KDE menu system) runs /usr/bin/kppp which I think is a pam-aware secure wrapper for /usr/sbin/kppp (or vice versa, I can't remember).
		When Kppp is running it docks itself into the panel where you can monitor its status or disconnect.

	Linux on PowerPC FAQ-O-Matic: How do I connect using kppp from a less privileged account (Site not responding. Last check: 2007-10-19)
		When I try kppp from a different login, I get the following message: "kppp is improperly installed - must be installed with the SUID bit set - contact your sys admin." I can only connect when logged in as root.
		Kppp should load up as if the session was originally root.
		This means that when kppp runs, it runs with an effective user ID (EUID) of its owner, in the case the root user, instead of the user ID (UID) of the user running it.

	KPPP not establishing proper GW \| MEPIS
		kppp connects and establishes ppp0 but when my eth0 card is up and the default GW for my LAN is active, kppp will not assign the ppp0 address to the default GW so my internet apps can find the DNS servers and resolve any addreses..
		Unfortunately, kppp seems to SEE that a Default Gateway already exists and DOES NOT replace it with the one obtained from my ISP.
		kppp app isn't doing what it should and that I even have to deal with this in the first place and secondly why there isn't an official reason/fix for it.

		Communication between the privileged portion and non-privileged portion of kppp is done over a domain socket which does not properly get closed.
		A fix for a similar vulnerability was introduced to the kppp code base in 1998 as can be seen below: // close file descriptors for (int fd = 3; fd < 20; fd++) close(fd); This fix may be easily bypassed if an attacker opens 17 file descriptors before executing kppp.

	Connecting to the Internet with KPPP (Site not responding. Last check: 2007-10-19)
		KPPP is currently somewhat flawed in design-- it requires that it manages the connection itself (you can't use your system's init-scripts to connect/disconnect) and it add differentiation between protocols (do your grandparents care whether their internet is using PPP, Ethernet, or SLIP?
		The reason why kppp differentiates between protocols is kppp is not an universal network connection tool.

		I was able to find analyzing kppp source that the problem occurs when calling tcsendbreak() syscall - it should send a stream of zeroes to modem for 0.5s or so and there is a timeout in kppp source around it to check if it will hang after 2s and report above error if it does.
		Now, even if I code around this, compiling kppp from source is real pain (whole kdenetwork package should be compiled actually), thus I think I'm rather going to spend some more time to find workaround.
