I know that ubuntu is highly resistant to windows based viruses but what if I open a attachment or click on a link within a email that is infected with a linux or platform agnostic virus?

i was thinking that is there a way to check data flow for viruses? i mean if i set up calm av in my internet sharing server could it detect anything in incoming and outgoing data ?!!
View 2 Replies View RelatedI've prepared a Samba fileserver at work without much too problems and I've prepared a batch file to mount it as z: letter on windows machine at startup.As a sad result the share gets filled with many viruses and became a vehicle of infection.
folder1 ----> folder2 and many other files and folders
folder1 has a condivision access read and write for everyone so I get no problems with passwords for all those who have access but i use ntfs security to do it read only (viruses act like if a pendrive is connected and mainly put infected files just in the "root" of it, in my case in folder 1) and then give everyone full control in folder2. I've been trying to understand how to do this but I'm quite new to linux and smb.conf really scared me. I've tried samba graphical tool which was a lot easier but I'm not able to achieve this kind of result: no need of user password for users to mount the share and no write possibilities in folder 1 and full control in folder 2.
I would like to use my Ubuntu 9.10 Karmic system to scan and clean viruses from Windows based HDD. I have KlamAV, AVG, and AVAST. I couldn't get F-prot to work. I don't find a debian package of it and don't know how to install tar.gz and the tutorials don't help a lot. Are there other antivirus solutions which are good for cleaning Windows OS but work on Linux/WINE? I wonder if I can install antivirus software in WINE and scan with no problem the hard disks.
View 5 Replies View RelatedI have been told that some virus scanners for linux (including but not limited to AVG, Antivira, clamAV, others) are available to ubuntu. My question is which of these still CURRENTLY support detection of WINDOWS viruses in addition to linux viruses. I would like to boot the Ubuntu live jump drive I have to scan windows machines and at least detect viruses, dont really need to repair. who knows which virus scanners compatible with ubuntu that will detect windows viruses as well
View 3 Replies View RelatedI am a very new Linux user. My first OS is Fedora 12, which I just recently installed into my laptop. So far, I am thoroughly enjoying it. I do have a question bugging my mind though. Linux systems are known to be very safe from viruses, mainly due to programmers targeting the Windows platform. In Windows, common methods for virus infections are from infected executable files, external drives autorun... ETC.
Now my question is how do viruses spread into a Linux system? And with so few viruses known to exist for Linux systems, do I really need to be aware and take precautions for viruses (For example in Windows, disabling autorun function for external drives)?
I read some articles about viruses in Linux and about some antiviruses which work in Linux and delete Windows viruses but I still don't understand: is there any antivirus which specializes in Linux viruses? Even though there are very little of Linux viruses, I know.
View 11 Replies View RelatedI have a dual boot computer. The WindowsXP "side" has been infected with a rootkit virus. So far UBUNTU has not been affected to my knowledge. I have not yet been able to remove the virus from the WindowsXP "side". I am thinking of deleting the NTFS partition and have the computer fully dedicated to UBUNTU.
Now for my question. Is there a possibility that the virus resides in the MBR and that I need to "rebuild" the MBR to actually remove the virus? Even more extreme, should I totally re-install UBUNTU in the name of safety and precaution.
I have set up a virtual machine under VMware Player 3.1.2 in Debian. Operating system of this virtual machine is a Windows Server 2003. I would like to periodically test this Windows Server 2003 installation for viruses. Obvious solution would be to install an AV software under this Windows Server 2003 installation. However, I was wondering, is this possible to use NOD32 for Linux or clamav in order to test this Windows Server 2003 installation for viruses? Is NOD32 for Linux able to detect viruses inside the .vmdk file?

View 9 Replies View RelatedI recently received an email from a friend without subject and just a link. Since we do that a lot, I clicked on it. I was taking to a website that looks like a phishing site and my computer hard drive started working feverishly. I closed it quickly.
First, I want you guys to be aware of this thing since it seems to be fairly new.
Second, I want to know if I have been compromised. I already changed the password on my gmail account and I accessed the site using Ubuntu and Firefox.
I was wondering how to block attachments to gmail. I am running squid 2.7 stab9 with dansguardian 2.10, users authenticated from LDAP. I have configured the POST restrictions in Dansguardian which does block all attachments to hotmail/yahoo etc etc but attachments to gmail continue to upload.
View 1 Replies View RelatedI have recently secured a server by preventing root from logging in via SSH. Now I log in with a non-root account and use 'su' when necessary.However, now I can't do something I used to do, which is open 'sftp://user@ipaddress' in nautilus and be able to edit files as root. Is there anyway to get nautilus to give me root permissions on the server? Or at least end up with root permissions in a GUI text editor on my computer? I don't mind if I have to use bash to start the process, once I can get a GUI for editing files.
Note 1: Yes, I realize I could ssh in and use nano/vi etc, but I'd rather use my graphical text editor.
Note 2: The server does not run X, so I can't just forward it.
The problem is here:When I was open gmail in my system Certificate Error is coming. The error details:
This Connection is Untrusted You have asked Firefox to connect securely to url, but we can't confirm that your connection is secure. Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.
What Should I Do? If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

View 1 Replies View RelatedThis used to work in Fedora < 15. Whenever I want to send an e-mail using Gmail's SMTP server for the first time in a given session, the KWallet system asks if I would not rather migrate the password and store it encrypted inside a wallet. Every time I concur and every time an error message pops-up, as soon as I try and send another e-mail. The attached snapshot shows the error message I get. It doesn't matter how many times I select "Store Password". Every time the ordeal is the same. Up to Fedora 14 this method worked all right, but now it fails.

View 3 Replies View RelatedSo on one of the Linux systems here (2.6 kernel if it matters), there's some weirdness regarding trying to ssh into the system. Basically, if you give it the wrong password on the first ssh attempt, it will give you two more attempts, but even if you give it the correct password, it still won't let you in on those subsequent attempts. (If you give the correct password on the first attempt, it will let you in.)
Example:
Code:
user1@machine1# ssh user2@machine2
user2@machine2's password: <wrong password>
Permission denied, please try again.
The system has sshd configured to use pam (i.e., UsePAM set to 'yes' in sshd_config), but I'm kind of a PAM dummy.

View 9 Replies View RelatedSo, I am looking to implement an FTP server with Isolated Client accounts/directories where a client can only access what's in their directory. I also need to provide my internal user's (content managers) the ability to upload, delete, etc from all of the Client accounts. The simple part is creating the secure client accounts. It's a matter of changing DIR_MODE in adduser.conf to 700 or 770, creating a user, having the FTP server chroot them to their home directory, revoke/restrict shell/ssh access and maybe even slap on some ACL to prevent botched permissions.The hard part is figuring out how to give my power users the ability to access all of their folders without thrashing security.
My first thought was to put all of the client user-groups in a parent group and having my internal users inherit group permissions..but you can't have groups inside of groups.My second thought was to put all of the client users in the same group and prey that the FTP chroot is enough to keep them from poking around but then I have the problem of how do my internal users access other user directories if they are chrooted. Do I create a second server without chroot.do I create some weird nested homedir structure..I honestly have no idea how to satisfy both requirements (secure client accounts and privileged user accounts). I need my privileged users to authenticate against Active Directory via Likewise open, LDAP, etc and I don't care how the clients authenticate. Though, I would prefer to have both file and FTP-server level protection just to make sure no one can see the other client's data.
I have my own dedicated server box running (using it for game servers). I access it via ssh and I have root control of it. It has FEDORA Operating System. I wanna give FTP control of different directories to different users. Right now there are no other FTP users except root. I have installed vsftpd and dont know what should I do next? How do I add users (who can read/write/delete files) and How do I restrict them to their home directory?
Here is what I want:
username:client1
password:12345
home directory: home/server1
username:client2
password:12345
home directory: home/server2
We use PAM to control access to our RHEL4 servers. We would like PAM to give a message, of our choice, when users who are not allowed to login try to login. PAM's default is to let the user try 3 times without any explanation.

I am not at all convinced by the idea of giving permissions to read,write and execute as these Learning Management Systems say. Let me know what you people have to say? What is the best practise in such situations? I have to get all these LMS run on same web server.
I have a log server that collects logs from all the cisco devices on our network.he company policy states that any logs should only be accessible by root. So I have the following permissions set on the directory, as well as everything inside the directory where the cisco logs are kept.
Code:
drwx------ 65 root root 4096 Apr 29 7:38 rsyslog
The cisco folks are requesting access to these logs, which is allowed by company policy.

use any browser and go to gmail. i can't get gmail to load. if i browse on videos, links to videos don't work. they appear to be taking a long time to buffer, then a message appears saying to try again. sometimes, links on google search pages are all dead. yahoo mail loads as far as logging me in, then i get a page with all dead links.
i'm using a laptop at several locations that have free public wifi. at some places, everything works perfectly normally. at other places, google and yahoo are almost useless. the "bad" places work just fine under ms windows.
so i figure it's a networking/handshaking issue, but that's all i can figure. i need help to troubleshoot it further. if it's happening to me, it has to be happening to other people, and i consider it a major hassle.
My college internet providers shifted to a different setting.. defined in the changing lan proxy settings on the user end. I.e.ip - 192.168.0.200 and port to 3000. This to reduce misuse of the net connection ..The thing is, since then, every other website is working, except GMail. It isnt blocked, the Nebero page shows up for blocked sites. When attempting to open gmail, the default internet page shows up for unavailability of page owing to no or slow response from the server, or the firewall or proxy settings not appropriately configured. I cannot open gmail, the connection on empathy im. I cant ping gmail either. No response. What can be the problem.
