Solved my problem > Perhaps for the people reading the thread on this list.... It is not a good thing the have the policy of iptables set to "accept", and drop what you want. If you ever misses one port, you are as vulnerable as you would have been without any rules. Better approach is: 1) to set the policy to drop everything, 2) allow what is needed, 4) log everything else. If you find you log gets to bulky, you can introduce stap 3) to drop traffic from specific port&address before everything else is logged. In this way, everything that you forgets, will be logged & dropped, instead of allowed in. hw ______________________________________________________________________ Dit bericht kan informatie bevatten die niet voor u is bestemd.

how to specify IP not equal to in iptables rules ????
by Jatin K 17 Jul '11

17 Jul '11

Dear All Gurus, I want to deny a particular IP (172.16.158.111) address in my network to FTP on server (RHEL6), I'm trying to add the following[1][2] iptabls rules on server and getting error [3] [1] iptables -A INPUT -s! 172.16.158.111 -p tcp --dport 21 -j DROP [2] iptables -A INPUT -s! 172.16.158.111 -p tcp --dport 20 -j DROP [3] Using intrapositioned negation (`--option ! this`) is deprecated in favor of extrapositioned (`! --option this`). if I try following [4] it throws error like " bash: !172: event not found " (I think it tries to recall a command from history ..may be not sure ) [4] iptables -A INPUT -s !172.16.158.111 -p tcp --dport 21 -j DROP So how to go ...??? and any one guide to the right direction ????? how do I add a rule like IP or the PORTs is not equal to ?

no sound on cf15 but yes system sound
by Zoran Spasojevic 17 Jul '11

17 Jul '11

I just installed FC15 with the latest updates. I am using M-Audio audiofile 2494. I get the system notifications sound but none of the audio or video applications produces sound. I tried using alsamixe and considered various suggestions I read on these lists but still don't have sound.. When I try system settings > Multimedia and click on "test sound" button, the reply I get is that the sound card does not work and it seems that it can not be detected by pulseaudio or various other applications. Thanks in advance for any help. zoran

Accessing MS Exchange 5.5 mailbox from Fedora 15
by Kevin Wilson 17 Jul '11

17 Jul '11

Hello, Is there a way to access MS Exchange 5.5 mail server from Fedora 15? I saw that for previous versions of Evolution there was a plugin called evolution-brutus plugin - for exchange 5.5 server but from what I found, this plugin is not available for fedora 15. I also tried with thunderbird, but I did not find out how. I want to add that I don't need to sync a calander, only to read mail. another thing is, a solution which will enable me to only read mail (and not send) is also good for me. Rgs, Kevin

how with export printers from remote session?
by Franta Hanzlík 17 Jul '11

17 Jul '11

Can someone recommends any solution for remote desktop connection (both side would be F14+ distros), which is able export remote printer(s) to connecting side? It shall be, if possible, working over relatively slow links (256+ kbps, e.g. xDSL). What I catch on, this should be able do with nx/freenx+freenx-server, maybe with rdesktop/xfreerdp+xrdp, but I never tried these. Or are there other solutions? Has somebody personal experience with this ? Thanks in advance, Franta Hanzlik

Re: Gnome 3 ~ Windows 8?
by Roelof 'Ben' Kusters 17 Jul '11

Hi There, This discussion will be an endless one - as there will always be people who don't like it; and people who do. Change always hurts, because you need to learn computing anew. And it's difficult for many to be humble enough to say you don't know how to do it - if you already know how to do it somewhere else. > One thing is sure: Your new user-base will not be your current (old) > user-base. Well, there will be overlap. I liked Gnome2, I adore Gnome3. It is where computing is going, like it or not. What we now know as desktops will in the not so very distant future be used only for servers and other large storage devices. Computing will be entirely mobile, and envision a little device on your collar (possibly in combination with glasses, but preferably without) that reads and responds to your arm movements, and projects your computing environment in front/around you. A keyboard will no longer be a physical thing, it'll be projected on the surface in front of you... Gnome3 is - although far from there - going in that direction. It is - like stated elsewhere - very suitable for PADs (I call them tablets, but whatever). On Desktops it's very possible to multitask btw, as long as you have a rather wide display... Then you don't need everything full screen. :) The movements needed for use of Gnome3 are very much Grab and Drag. I can see myself doing this sitting in the garden with a matchbox strapped to my collar... Meanwhile, many things do indeed need to change, or at least be improved in Gnome3 (Fedora 15 is my only reference). Indeed, Power Off (Shut Down, whatever you wish to call it) needs to be there standard - and not through a plugin (btw, yes, there's the Are you Sure option, where you can also decide to reboot). I'm looking for a better notification/taskbar equivalent. Right now, only the program on top is shown. More space needs to be made for more open programs. For example, I use XChat while gaming. There is no notification what so ever when there's activity on the chat channel - because there's no space for anything to blink. And there are more things, but they've been repeated ad nausea (is that the spelling) so I won't do it here. > I'd expect people, who are attracted by the kind of GUI, Gnome 3 tries > to implement, to choose the original, i.e. Apple, Microsoft or Google's > products over Gnome 3 (which means them not ot use Linux). There certainly will be some going that way. I am not, and I know a few people who are with me. P.S. Sorry, this mail took overnight to compose; a crying kid can be awfully distracting. :) -- Greetz, Roelof Kusters aka Ben The internet isn't a highway, it's a swamp: the more you surf, the more it draws you in.
