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.

I'm running 9.04, and wanted to use GMail's talk and video features. Registered with Gmail, and had to install a deb called google-talkplugin_current_i386.deb , and after installation, Gmail appeared as if it was ready/ok for a chat, talk or video.
Then I noticed the .deb was not shown under Synaptic, as a 'standard' deb, so in the interests of some 3rd party software NOT running on the computer, uninstalled it.
Went looking in Synaptic, and it does have a 'gtalk'. Is that all that is required, to run talk or video under a web browser, after logging into my GMail account ? Or, should I use Empathy ?

I have an issue in Gmail that has just started recently. When I'm logged into Gmail I sometimes have as many as 22-28 outbound connections and my NIC never stops sending and receiving data.When I log into Gmail this starts and doesn't stop even if I log out and close the tab. I have to quit the browser to lose the connections.
I had a thread URL... that initially was about this issue but I didn't know it seemed to be totally Gmail related so I thought I might ask this way. It could be Google just changed something on their end but I don't want to run my mail until I know it's ok.

I created an account for my brother but it's a very limited account, just so he can browse and listen to music and stuff like that.However, what I do find funny is the fact that accounts are secured with a password but limited accounts can browse to /home and see the files of everyone, even admins, without Ubuntu asking for a password.I obviously do not want this to happen.Anyway, is there any way I can block him from being able to browse to my homefolder, other than encrypting it?

We are trying to set up a classroom training environment where our SIG can hold classes for prospective converts from Microsoft/Mac. The ten machines will have /home/student01..10 and /home/linsig01..10 as users. We want /home/student01 to be able to explore and sudo so they can learn to administer their personal machines at home. We don't want them to be able to modify (sudo) /home/linsig01. I've seen the tutorial on Access Control Lists but I'd like other input so we get it right the first time.

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.

I have FC-4 with Squid and Dansguardian. Internet Users in my organisation are configured to use proxy with 8080 in browser IE. There's no issue with Users as DG working perfect for them. We have Business Development Team, as they need to do most of the research over internet, their IP's are included into "Exception IP List" in Dansguardian. Obviously these people will be excepted from all banned sites, BD Team able to do chat, play games and do social networking and other stuff over the net, which results in more bandwidth consumption and breaking office policies.
I have tried to implement SQUID ACL's to block few sites like " meebo.com, orkut.com,facebook.com etc" but SQUID acl's not coming into picture. any one who successfully blocked chat, banned sites and social networking in DG with my case.

This 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.

I 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've got a request from one of my company's subsidiaries to block all incoming and outgoing mail for a group of users. I've read up some guides on access.db and I know how to do that, but now they want to allow these users to receive emails from a few select domains, and block the rest. To summarize:
1) Block all incoming and outgoing email to users in team A, except mail from [URL]
2) All other users can receive and send mail from/to any domain.

We have 4 servers having rhel 5.2. We have several users logged in on one of them. We have nis server/client running on them and have common home area mounted on all of them. Now we want to disable/block the accounts of the users who have not accessed our servers in last 2 months from today. What logic should we apply to do so? We were checking stat of .bashrc of each user but is not correct logic. We are going to write shell script for the same. We don't want to do anything in users home area or their files.

To avoid having to input a password for the keyring each time I connect to the net via wireless, I enabled the 'Available to all users' option in Network Manager. Now, my question is this. Are the 'users' it refers to just those created on this machine? Would a drive-by be able to use my network without entering the password?

I have an environment with multiple projects that have a variety of government and commercial sponsors. We have been satisfied to this point with a netapp serving nfs/cifs and keeping a tight reign on nfs exports.Some of these projects have started asking us to provide access restricted sub-folders of the project space based on different groups that contain a user subset of the primary group.
We have a linux machine that serves as a version control front end to the netapp, mounting the project spaces via nfs. People are now mounting their project space via sshfs to this "front end" and sharing the root password of this sshfs client with everyone in their project, in turn creating a security hole to access the so called restricted sub-folders. I know all the obligatory responses referring to irresponsible user behavior but would like to see how others have addressed something like this where user behavior seems out of control.

I'm running Fedora 15 64-bit on my laptop, an HP HDX. I installed skype and got flash video to work (the former required that I install some 32 bit libraries, the latter required that I install an experimental 64-bit flash plugin from a tar ball). Now, they both work fine, but they don't work at the same time. In other words, I can have a video/audio chat, or just an audio chat, with someone on skype, but during that chat, I cannot view flash videos, nor can I watch a movie (and I verified that the problem is not just with totem) at the same time. If I'm watching a movie or listening to audio, skype will refuse to make a call.
Furthermore, when I have the sound settings open, and I'm using skype, in the applications tab of the sound settings I get "No application is currently playing or recording audio" which seems highly suspicious. I know this is a fixable problem because skype 64 + flash and/or movies works fine in the most recent iteration of 64bit ubuntu on my laptop, so it is just a matter of settings. I can't find much in the way of pulseaudio or alsa management apps in any of the repositories.
