Mar 16, 2010I have a desktop computer running Debian Lenny, a 56 K modem, and a dial-up account, currently configured like this: computer -> modem -> UPS -> phone jack
When I run off a Knoppix live CD, I can use kppp to configure pppd (using PAP/CHAP authentication and hardware control flow) to dialup and surf. When I try to user kppp to configure pppd exactly the same way on my hard drive installation, I get nothing. Both my Knoppix live CD and Debian Lenny use exactly the same version of kppp, but the pppd related files in /etc/ppp look a bit different.
Under both Knoppix and Debian Lenny hard drive installation, when I try to connect, the login debug window of kppp shows:
Code:
ATZ
OK
ATM1L1
OK
ATDT [phone number]
At this point I hear the modem dialing out, and when using Knoppix, after a few seconds I see
Code:
Which I think corresponds to my route to the InterNet being established through my ISP. When using the hard drive install, I never see the CONNECT, and all indications are that my modem is not sending authentication information at all, but getting stuck right after dialing out, so that my ISP gets a phone call from a modem which... refuses to speak. I never had any problems before, so I am baffled.
So apparently my system is currently misconfigured in some way which prevents point to point protocol from getting out.
Questions:
I have a firewall on my computer which I set up using guarddog. I have enabled point to point protocol from internet zone to local zone. I know that ppp is a symmetrical protocol, but my understanding is that I do not need to enable point to point from local to internet zone. I have not enabled irc protocol because my understanding is that this is only relevant to software flow control using chat scripts. Does this sound correct? Is there some additional protocol I need to allow in order to use pppd to dial out?
When I reboot my computer (off the hard drive) I sometimes see that the system complaining about a failure to stop every process, and sometimes I see mention of an eth0.pid. I have been looking for lock files; would they all be in /var/run?
When I use kppp to configure pppd, I want to do that as my ordinary user for at least two reasons, correct? don't want to run pppd as root user for security reasons kppp is a GUI and root user can't use X (on Debian)
So I should see in home directory of my ordinary user
.kde/share/config/kppprc
.kde/share/apps/kppp
But not in /root directory, correct? What pppd related processes should I see with ps -ef if everything is working?
General :: CentOS5.4_x64 - Open Up Ports In Firewall?

Mar 5, 2011I'm looking forward to the release of openSUSE 11.4, which I'm looking to install as an Internet facing gateway on a mini-ITX machine with 2 Ethernet cards. As such I've been reading up on the YaST Firewall trying to find out to configure it, and there's one thing I'd like to be able to do: 'stealth' all the firewall ports.
In other words, if someone were to hypothetically do a port scan of my external IP address, I would rather they not know whether any of the ports on my gateway are open or closed, so instead of replying with the status of those ports the packets get dropped. I've been able to do this with a product called Astaro Security Gateway, which I currently have installed on a second hand Dell Optiplex machine, but I am now looking into the possibility of installing this as a virtual machine inside an openSUSE 11.4 host (extra level of security) and would like the same functionality for the host OS.
Networking :: Configure My Firewall (through Iptables) To Allow Apt-get Features
Apr 26, 2010I am encountering problems to configure my firewall (through iptables) to allow apt-get features, like update and install.I have the latest debian server running in a virtual machine in my windows xp and therefore I have two interfaces in this debian server:- NAT Interfaceinet: 10.0.2.15- Host Only Interfaceinet: 192.168.56.101So far my iptable rules drop all packets for default, in exception icmp and ssh that I allow to ping and connect from my windows xp. Both of them I use only the Host interface (192...) to connect to another 192... interface on my windows.
Those are working fine, but apt is not. I know, in this very moment it shouldn't. But I made a lot of attempts trying to configure the iptables allow connections through the 80 and 21 ports from/to NAT and Host. I think I made all possible combination (or not, because it didnt work). But I'm wondering if someone more experient can help me solve this problem.
