I'll start here with my concerns ... version 9.04 onwards does not work gives blackscreen. I think "forgotten" by the generic drivers for ATI or something that influences the video. it does not show. 9.10,10.04,10.10 none of those versions worked ... on other computers functioned normally. I found researching how to dribble and go to live. and thus unable to install. but does not work after the pc restarts. Linux does not. shows nothing ... goes to black screen with the (- FLASHING) but nothing else happens.

[Code]...
The problem is that everything works fine ( i have the same rules for other services such as samba, nfs, mysql on another server) BUT ftp there is no way to make it work. not even locally.when i try to connect, i log in, but while listing the directory i get MLSD ... and it hangs like this for a moment, then i get error message "connection time out" , "impossible to list directory". if i turn off the iptables script no problem,ftp works fine.. but why all services work and ftp no?
how do i have to modify the rules? what is strange also is that if i set as OUTPUT policy "accept", the server seems to be offline."host unknown" error message. I was thinking the rule INPUT is fine cause at least i can login, but the dir list is not going out, so gotta modify output rules. or state?
Regarding the usage of our PKI, some security consultants suggested to let our root CA offine (hardware online but disconnected from the network). However, when it is offline, I don't understand how to sign certificate request or to publish CRL. How a PKI works with the root CA offline? USB sticks?

The window opens without problems in my dad's session, so I guess that if I delete some config file in my /home it will get fixed. where are the gwibber config files? I couldn't find them =/

I installed 9.04 clean yesterday to try and once again move from Windows to Linux and I thought I would give it a real try this time to learn the new OS. Well, right off the bat my wireless connection does not work. By default my WPA/WPK security was set on my router. My wireless adapter does connect to the router but there is no internet access. If I remove the WPA/WPK security and leave it open I can connect and I do have internet access but as soon as I re-enable WPA/WPK security I lose internet access. I even tried WEP security and same result. What the heck is going on with this? I am not going to leave my router unsecured but that seems to be the only way this works. I also upgraded this morning to 9.10 and same problem so this is not limited to 9.04.

I know Ubuntu doesn't really become the receiving end of Virus and melware but IM one of those users that proves that there are virus out there for mac and Linux.Like a few years ago (back during 8.o5 Ubuntu i think i downloaded a hefty amount of software with out considering the recourse Thus I became the receiving end of a nasty Ubuntu target virus sucked and at the time it ruined my fun so i went back to the windows virus any ways I'M looking for a virus protector that works on Linux as I tend to be Very.. *ehem...* dumb when it comes to what not to download
so ya other then avg (i had that on windows virus and its awful)also could I get an idea of things NOT to download?
i have setup auto ssh login for my server. And it works, but only when i have a active connection. if i use "ssh server.com" it asks for my password. If i then open a new terminal and issue "ssh server.com" it logs right in. I really don*t understand whats wrong.
I have tried setting up 2 virtual machines on my local computer and with the same setup it works fine.
SOLVED: my home folder was encrypted, so when no users were logged in the home folder was unmounted
I've added my public key to the remote machine's authorized_keys file, and I can ssh over without password. But when I try to mount the remote share using sshfs it -always- asks for my user's password. I have set sshd_config|PasswordAuthentication no
... and when I mount the share as root it says, "read: Connection reset by peer". My mount is being done as user, so it shouldn't be a root authentication problem:
sshfs#bill@droog://media/droogfuseuser,noauto,gid=6,umask=007,cache=no,ServerAliveInterval=15,reconnect,allow_other,comment=sshfs 0 0
I can't mount as user because /dev/fuse is not suid, and I'd rather not set it such.
Is there a free online vulnerability scanner where either I can give them the IP address to scan or can be initiated from the console command, tool, or text based browser. I use GRC's Shields Up when I have a GUI, but I want a scan ran on my website that runs Ubuntu 8.04 server on a hosted VPS.
View 5 Replies View RelatedJust to confirm - I have come to the conclusion that it is best to have separate Ubuntu installations if users of the same computer have different default firewall blocking needs. Me and my wife have totally different Internet surfing habits. I also tend to block most of the websites that she normally uses, some of which are dialed by default when opening Firefox.
We have used one desktop computer for a while now with two users in one Ubuntu installation. It is becoming too much of a hassle having to change the firewall settings each time it was changed by the other user with a previous log-on. We also have two other computers in the household for the children. I have created a Local Repository, and download updates only on my computer, saving on time and bandwidth (the only replication that takes place is downloading the index files from the update servers for each computer). Having another Ubuntu installation on the same computer will just add to the "auto update" list.
Another advantage is that my "more secure" Ubuntu partition (which may contain sensitive information from time to time) will not be mounted when my wife is on the Internet.
I am using the Fedora 13 Live USB on my Gateway MT6451 laptop. All the major things you want to work on a laptop with linux actually work! Even my Broadcom wireless card! But even though I can see wireless networks and connect to ones that are open with no problem, I can't actually connect to my Hidden WPA2 network. I put all the information in and it connects, shows a good signal, but doesn't acquire the correct IP. I have a 192.168.X.X address range on my network, but it shows a 10.X.X.X ip and no Gateway address.
If I can get this one thing working I will definitely be installing Fedora.
If I forward port 5764 to port 80 to my VOIP device, I can nmap and get a proper connection. If I forward port 5764 to port 22 to my server, it comes up filtered. It even happens if I try forwarding port 80 to my server. So I'm sure it has something to do with my server, but I'm not sure.Here's my Linksys iptables:
Code:
:wanin - [0:0]
-A FORWARD -i vlan1 -j wanin
[code]....
I'm having a mare with SSL with Apache. I have set it up and if I go to the follwoing address http://192.168.1.2 it seems to work and the pages are delivered to my browser. However if I try to access it from an exernal PC it will not work.
I can get to the non-ssl part of the site so the static ip is resolved and the port forwarding all works.
Does any one have any ideas (and in fact i think I may have just solved it - Ports - 80 mis open but I haven't done anything with 443. Will check it out and post back.
i am relatively new to ubuntu. Just recenty i have not been able to access certain files(for example the history and bookmarks in the firefox folder), download files individually from the internet(music,fonts,etc), recieving an error message

i have sudo priveleges and can install via update manager. i read somewhere that compizfusion might affect access permissions and i do use compiz and emerald at the same time.
Can a virus survive a reformat, running bootrec /fixmbr (both from the install CD), and then installing Ubuntu? Reformat meaning from the windows disk recovery console, using the format command for all partitions. Likewise, would a virus be capable of surviving just the first two steps alone without installing Ubuntu, just re-installing windows?
If one were to have an MBR virus on Windows or Linux, how abouts would you find or remove it without doing an entire disk wipe? And before someone goes "Linux is immune" take into consideration vulnerabilities on the user end.
I was on funnyjunk.com yesterday, looking at funny pictures. I clicked the next button, and a page popped up displaying that the website had malware hosted by hit.d1.net, however when I had Windows XP the MacAffee Siteadvisor Displayed that there was no malware. Is this Real or Fake? Just wondering if it is one of those fake spyware alerts, like from windows.
View 2 Replies View RelatedI realize that FF 3.6 was referred to near the end of this thread? Most Ubuntu based distros (Mint, Gosalia, Ubuntu, Xubuntu) are shipped with FF 3.5.8, are there any reported problems with this version of FF? Mint does offer Opera, I really don't care about installing Wine to gain access to IE6, you open the browser, there are two critical updates that shows, but on three occasions, I left the desktop for an hour, and the two updates still never applied. I have installed Clam AV, is there a malware scanner for Mint, too? I do want to be secure, but don't wish to run two AV's, have four separate malware scanners, and scan every piece of everything the way you must do in Windows. With Windows, you spend more time scanning than browsing. I don't want to have to do this with Mint, too.
View 5 Replies View Relatedis it possible for malware to survive a full reformat (ie... dd /dev/zero,urandom,zero?I'm for some reason worried that my android based phone, PS3, XBox 360, Routers, and/or TV can somehow be infected with malware as they were hooked up to my network..Is this possible? And does Factory Resetting or Hard Resetting clear all data on the device and reset it entirely? If so, how does that work? Is there a specific storage chip on the device that cannot be written to and only read for when a hard reset is requested?
I'm aware that this sounds outlandish but I've got a severe paranoia for some reason and would like peer advice on how to resolve this and get some peace of mind.
So I downloaded a movie from megaupload and a pop up came up with [URL]....that bounced me to[URL]..but that webpage did not display. Normally, on Windows, I would have an anti-virus that would likely give me some sense of good or bad websites. On Ubuntu, I am not quite sure. Do I need a malware scanner for the firefox browser? I have the standard package from the 10.04 distro with the latest updates...

View 9 Replies View RelatedIn Ubuntu 10.04 LTS, I have downloaded and installed texlive (2011). They have issued the following warnings:
1. "To the best of our knowledge, the core TEX programs themselves are (and always have been) extremely robust. However, the contributed programs in TEX Live may not reach the same level, despite everyone�s best efforts. As always, you should be careful when running programs on untrusted input; for maximum safety, use a new subdirectory."
What does this exactly mean? The installed program has already created own directories and subdirectories (e.g. /usr/local/texlive/2011/bin/i386-linux). Am I supposed to create a new subdirectory in home to write files and run latex program? Exactly how do I know that the downloaded and installed program is not malicious?
2. "Finally, TEX (and its companion programs) are able to write files when processing documents, a feature that can also be abused in a wide variety of ways. Again, processing unknown documents in a new subdirectory is the safest bet."
what is implied by "a feature that can also be abused in a wide variety of ways".
I have been using the new ocr app 'cuneiform' that has appeared in the Lucid repo.It is command line and works very well.However, the rest of the household would like to use it and desire a gui front-end.Mepis has this and it is called YAGF. Works well.We are told to install only from trusted sources.how can I check the integrity of this .deb and freedom from malware before installing it?
