Ubuntu :: Sky Webmail Ok But Password Failure With Email Clients?

Oct 21, 2010

I've configured more email clients over the years than I care to mention so I am by no means a newbie at this so when I set up linux for a friend recently (10.10 on a laptop) I came across this problem, the install went wonderfully btw! The fix, long story short, if you are a sky broadband customer and are just setting up your email, you'll have a letter informing you of your email address, you log on to sky.com/resetpassword (or similar) enter some credentials and enter a password. This worked fine with the webmail, log in no problem, configuring a client (Thunderbird and Evolution) resulted in receiving a login failure with the message similar to 'credential failure' or words to that effect.

So after entering the password again and again, reading and re-reading the sky.com site instructions on setting the correct security settings, checking the correct ports, checking the correct settings to allow an IMAP connection from within the webmail interface and still getting no where I did this: logged into the webmail interface, then 'mail settings' > 'accounts' > then 'google account settings' then 'change password', this opens a sky.com reset password window. choose the my security question option and use this to enter a new password and this worked.

I suggest not using the 'my email address' and 'send an email with a reset link' option, this was attempted first and resulted in the same issue, new password set for the webmail but still not working with an email client. It seems that, and I'll be corrected by anyone who knows for sure, that their software is currently not updating all the passwords held if you use the 'reset password via email link'and neither did the initial setting up of the password work correctly either. My best guess is the passwords are going out of sync with their email servers not being updated correctly in all circumstances. Once I had reset the password as described it worked first time, so clearly there is something in this.

For info the settings for IMAP:

[code]...

outgoing mail settings:

[URL]
security: use name and password
connection security: use SSL
port should be set to 465

[code]....

Security :: Invalid (Untrusted) Certificate - TWC Webmail

Oct 7, 2010

At the login webpage of <[URL]>, the Time Warner Cable (TWC) Webmail site, I am immediately confronted with a warning that the Security Certificate is invalid & that the site is untrusted. This occurs with Firefox, Seamonkey, & Konqueror. This does not occur on Microsoft or Apple systems; I have checked other colleagues machines. I have manually overridden the warning & everything functions fine. I have contacted TWC & am awaiting their tests. But, I would like some independent corroboration from other users in the Linux community. Could some of you perform the test yourself on this URL? An error will be readily apparent.

Security :: Secure Webmail - SMTP Relay In DMZ?

Apr 11, 2010

When you set up a webmail solution these days, either on your home LAN or at a small business. What steps do you take to make the solution as secure as possible? A couple of years ago it was sufficient to port forward both port 25 and 80/443 to you server located on the internal LAN. Today you're more likely to have a SMTP relay in a DMZ of some kind. But the webmail, how do you solve this? Do you place a dedicated webmail frontend in the DMZ and open ports towards the internal LAN, or do you just place the entire server in the DMZ? I'm looking for input for a small network/home LAN so it shouldn't be to complex.

Ubuntu :: Linux Ignoring Windows NTFS Permissions & Security Settings?

Apr 26, 2010

I have NTFS-protected directories under Windows. However under Linux, even though I'm not logged in as a Super-User, Ubuntu cheerfully mounts all NTFS partitions on this machine and EVERY computer on my home network. This gives my GUESTS complete access to all machines connected to my network: Nautilus -> Windows Network -> Workgroup -> Clicking on any computer Name gives access to windows' administrative shares C$, D$, etc. I've always known that Linux ignores Windows security, but... what is the solution?

Ubuntu Security :: Yahoo Spamming With Email (Vista)

Jul 7, 2010

My Email Address is spamming

1. I received an email (spam) on Yahoo Mail from someone who was not intending to send it. (While it did go to spam folder, I did 'open' the email (since it came from a trusted sender) but it only contained a link (which because of WOT) I assumed was spam.) I did NOT click the link.

2. I then informed him that his email addy was spamming.

3 Shortly thereafter, i noticed in Ubuntu (firefox) whenever I clicked "reply" to email back to someone, there was a quick flash of letters/numbers in the slot where I would normally write. This instantly disappears and goes blank so I can write something, so I just figured it was a bug. This is happening on BOTH windows and Ubuntu.

4 Now MY EMAIL is spamming people the people I write to.

So far: I have 1. Changed my Yahoo password 2. Deleted firefox 3. In windows Ran Spybot/Search-Destory AVG (turns up nothing) What else can I do?

Ubuntu Security :: How To View Email Attachment Without Risk

Oct 30, 2010

I have received an email with a .csv attachment from a bank, and need to know how to view the attachment without risk. Using View>Message Source I see a large solid block of random upper and lower case characters, whereas I would expect to see some readable text mixed in. The email subject and the attachment name both contain data specific to me, but the text of the email consists largely of disclaimers with no mention of my name or any clue as to the nature of the attachment. I am using Thunderbird as my email client.

Ubuntu Security :: 11.04 - Automated Email With Unclickable Link

Jul 12, 2011

I'm fully aware that Linux, and Mac OS X are a far reach from Windows when it comes to viruses. I run Xubuntu 11.04 on the netbook, and Mac OS X 10.4 on a Mac Mini. But, and I now wish I kept the email and didn't delete the account, but the following happened recently: I received an email, from myself (I was on my own contacts list) that was sent to a few others on my contacts list - an email I did not send out. There was no subject, and an unclickable link that - once copy/pasted and gone to, was "Forbidden," even when you took the /s away and went to the main site, it was "Forbidden." It was a .be website (Belgium). Being that one of the recipients was "noreply@craigslist.com" I can only assume that this email was automated.

It was only sent to a few addresses, all of which were tied to my account. I changed the password, deleted my contacts, and deleted the address (and have a new one elsewhere). I ran ClamAV on here, an antivirus on my Mac Mini (and I'm running a different one now), and thus far, absolutely nothing. So my question is - Is it, then, even reasonably possible that either of my computers are infected, and if not, how did this occur? I'm just taken aback a little, considering I don't use or have Windows on any machine that I own, and extremely rarely use Windows when elsewhere (and not at all recently).

Security :: Rkhunter's Email With Several Warnings

Last night I received the classic rkhunter's email with several warnings inside:

Quote:

Warning:

Warning:

and so on..

Why rkhunter isn't able to calculate the hash of those files and compare it with the stored one?

Other strange thing: for the "good" file, the hash is often different!

For example, in the last rkhunter.log, /bin/awk is "good".

But:

So, if the sha1sum is different, why rkhunter tell me that awk is secure?

Ubuntu Security :: Security Changed In Remote Desktop?

Jul 6, 2010

I always use VNC to check my server for updates, and this morning I started the xvnc4viewer to vnc into my server and it keep asking for a password. I never setup a password because I do this local from my laptop, and I am the only one who uses my laptop. I had to go to my server and check the setting in System > Preferences > Remote Desktop and found them all changed. There was a password setup and there was a check mark in the you must confirm each access to this machine there some security update that changed all these setting? Sometimes when I do updates I don't know what is being changed on my server

Security :: Securing System For Email Abuse

Jun 25, 2010

I have a mail server that accepts to relay from system in the trusted network. One of the systems in the trusted network is a webserver. On the webserver there are several scripts that send email.Let's focus on the PHP scripts. These use the mail() function for that.I am looking for means to reduce the potential abuse of the mail server when one of the PHP scripts is hacked.For the situation that the code is modified by a hacker or a new script is installed I would like to take this approach:

1) scan the system for scripts using the mail() function
2) generate a checksum list from these scripts
3) intercept email (being sent to sendmail) from these scripts
4) check if they match the checksum list

In theory (I will still have to implement it) this would take care of the situation in which new/modified scripts try to send email.

However, there is also the option of an exploit of some script. Are there any ideas on means to prevent email abuse for this situation (other that: make sure scripts cannot be exploited )?

Ubuntu Security :: Real Time Email Virus Scanning In Lucid?

Jun 14, 2010

I am building a PC that dual boots Kubuntu and Windows and want to share the email store. Therefore, I would like to have real time or on access scanning of emails in an antivirus program like Windows does. I am not running an email server, just a desktop using pop3 and eventually imap email.

In previous Debian versions ClamAV and Dazuko used to do this. However, I understand that this setup doesn't work in Lucid. I tried p3scan but that hasn't been updated since 2008, once I managed to install it, it failed to find clamd even though it was running. I understand that clamdrib no longer works for Thunderbird 3. Amavisd as a replacement for p3scan, but this seems to be for mail servers.

I would be really grateful if anyone could tell me how to get on access/real time virus scanning of pop3 and imap emails on a desktop running Lucid with either Thunderbird 3 or Kmail, without having to buy an antivirus program like Avast Or point me to an existing tutorial that I might have missed.

As an aside (don't want much do I?) does anyone know if Kmail can be setup to only download the headers like Thunderbird does?
