<0> I don't need good documentation on netfilter, I need to know if my "fix" worked
<0> how do I test it
<1> are you asking me -how- to test if your system no longer responds to ping?
<0> oh, well I already know the answer to that; I thought it might be something else
<1> for the record, I don't think you ahve solved your problem.
<0> anyway, how do I protect against Syn flooding attacks?
<1> you rate limit them
<0> I did fix the problem by turning off ICMP alltogeather: `echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all`
<1> tybalt: you can do that, but it ****s up source quenching among other things
<0> I don't know what source quenching is, is it something I might need to use for a server?
<1> it's a basic flow-controll implementation
<1> if you don't know what you are disabling, you probably shouldn't be disabling it.
<0> well, I know I am disabling ICMP which is ping
<1> no
<0> how am I not doing that?
<1> ICMP is more than ping. ping is icmp_echo_request and an icmp_echo_reply
<1> http://en.wikipedia.org/wiki/Internet_Control_Message_Protocol
<0> yes, it's a request and reply; but if I blocked all ICMP messages then I have blocked ping.
<1> yes. as well as a large amount of other stuff
<1> a computer with all icmp blocked is like a cop car with a busted radio
<0> no, its a cop car with a one way radio
<1> if you only block it one way, sure. in this case though, said cop car is only able to report out
<0> ok
<1> most ICMP requests require a response though, and that one you won't get.
<0> yup
<0> anyway, how do I set a better rate limit to protect against Syn attacks?
<1> I really think you should just look into a firewalling script. I used shorewall last, it was rather nice
<0> no gui
<1> shorewall doesn't have a gui, no. this is one of the good things about it ;)
<0> why have people bad-talked shorewall on forums? they then turn to self-made firewall scripts...
<1> tybalt: I dont' see how I could possibly answer that. I suspect those people either didn't know any better, or needed some very specific functionality that shorewall didn't provide.
<1> You however are asking for basic functionality, and frankly, I don't think you have the skill to build your own firewall script. atleast not one that will actually be water tight
<0> well, I already have my firewall set up the way I need it using my own script (just a bunch of iptables calls to allow certain ports)
<0> would you be willing to look at it and tell me what you think?
<1> no
<2> How can i remove the p***word prompt of the CVS ?
<2> cvs -z3 -d :pserver:bleh@bleh.sf.net:/cvsroot/bleh co bleh
<2> that ask me for p***word
<2> but its anonymous so that dont have p***word ..

<3> men i just wanted to know if some of you could help me
<3> jajaj
<3> no man
<5> ****son-slac: It's as simple as you messed up.
<3> ok
<5> ****son-slac: There is nothing we can do about it
<3> but can't you tell me how do you compile a kernel 2.6??
<3> to see if i'm soing well
<3> just the comands
<3> after make menuconfig
<5> It'll be slightly different for me because of the whole debian-based distro...but...
<5> make-kpkg clean && fakeroot make-kpkg --initrd --append-to-version=-custom kernel_image kernel_headers
<6> hey reality
<5> Yeah?
<6> man usermod then what else?
<5> Viperserv: Then you read with your eyes
<7> what is the name of the program to parse a certain column from a string?
<6> ah ok
<7> for example: root 34654 1.0 ...
<7> and I want the second value
<5> deadeyes: sed
<7> reality_ can I do it without sed?
<7> I thought there was another program for it
<5> deadeyes: maybe awk
<7> found it in my book:) the command I wanted was "cut" :)
<6> anyone use vsftp?
<7> have a problem with sed, I want to parse the procesid from the ps command
<7> I use: sed 's/ */:/g' ...
<7> but what I get is that between each letter I get a ":"
<7> I just want to replace the multiple spaces with a ":"
<7> fixed it:)
<7> sed 's/ */:/g' ... (there has to be 2 spaces:))
<8> yo
<9> is awol usually in here?
<10> anybody alive ?
<11> anyone here have roadrunner thru warner cable?
<12> hello all.
<13> I'm new to linux and I just installed Fedora Core 6 on my desktop on the Virtual PC
<13> I'm having trouble with my video card or probably my monitor
<13> because the graphics looks really messed. I can't see anything at all
<13> how can i change the settings to start off linux?
<12> Gee. It's quiet in here too... not like the old days.
<10> anybody online ?
<10> how can i install oidentd on RedHat 3 ?
<10> ES release 3
<14> how can i compile a .c file using gcc ?
<15> comrad: something you wrote yourself??
<15> comrad: because it somewhat depends
<10> Stegul can you help me ?
<10> rpm -i oidentd-2.0.3-fr1.i386.rpm
<10> warning: oidentd-2.0.3-fr1.i386.rpm: V3 DSA signature: NOKEY, key ID e42d547b
<10> error: Failed dependencies:
<10> pidentd conflicts with oidentd-2.0.3-fr1
<10> rpm -e pidentd
<10> error: package pidentd is not installed
<10> why ?
<10> how can i remove that pidentd ? so i can install oidentd ?
<15> porky: well, firstly it's a good idea to use something a bit more high-level than raw RPM
<15> and secondly, there's probably a fuller package name that needs to be p***ed to rpm
<15> try listing packages and picking out the package name from that
<10> and what to use ?
<10> tell me please the comands please
<15> I don't know
<15> I don't use rpm-based distros
<15> porky: what distro *are* you using?
<10> Red Hat Enterprise Linux ES release 3 (Taroon Update 8)
<10> 2.4.21-47.0.1.EL #1 Fri Oct 13 18:04:55 EDT 2006 i686 i686 i386 GNU/Linux
<15> porky: well, consider reading the redhat manual about how to manage packages
<15> it will tell you there
<10> Stegul i know how to install the oidentd
<10> but i don't know how to remove that pidentd
<10> please tell me how to remove it and i will be off
<10> rpm --query --list pidentd
<10> package pidentd is not installed
<15> I don't bloody know
<15> read the bloody manual
<10> where from ?
