Security :: Getting Rid Of Certificate Requirement In MUTT
Apr 7, 2010
When running MUTT on a RHEL 5.4 box, I get the message:
------------------------------------------------------
Server certificate has expired
This certificate belongs to:
localhost.localdomain
Unknown
SomeOrganization
SomeOrganizationalUnit
[URL]
I choose "accept always", but the same message appears next time. I do not wish to have a certificate requirement for MUTT and did not intentionally set the program up to include this feature. How can I get rid of it? My second choice would be to get a new certificate, but then I have to go through this every year. I have MUTT working on two other servers and this does not happen.

I have a certificate froma CA that I want to use with Mutt. I have been using this certificate to sign emails in thunderbird and I don't want to send emails from mutt without it. I looked on Mutts website, but I wasn't able to make heads or tails of it. I found something on Google about gpgp certificates and wanted to know if that would be the same type of instructions.

The iptables has every rule set correctly, the users in the subnet works great, but I have the following issue.every user connect to a mysql running on the internet through the port 3306, the forward and masquerade do the job. Now I have a user in the outside, and he wants to connect to a mysql in a certain machine (Not the gateway), prerouting rules solve my problems, but all the packages from the inside users goes now to that certain machine. I would like something like if the package passed trough masquerade don't pass trough the prerouting rule, and if it come from the outside (Not a package that come from a petition from the inside) pass trough the prerouting rule.

I am having issues with using OpenSSL. How do I view the currently used certificate? Also, do you know of a good site that has instructions on how to install a certificate. The previous user installed a GoDaddy cert for an FTP server and I need to update it because it's expiring real soon.

Got F13 installed yesterday, this afternoon I suddenly started getting Secure Connection Failed warnings. I'm not sure whose problem it is because it mentions uses an invalid security certificate.This certificate is only valid for *.opendns.com(Error Code: ssl_error_bad_cert_domain)It continues to say that someone could be impersonating the actual server. I am still receiving mail through google and my google calendars seem to be working. I do use OpenDNS for my DNS instead of my ISPs (Comcast which would very often slow down) and obviously I use IMAP mail with google on Thunderbird. So is it google, or OpenDNS, or Thunderbird that has a problem. Firefox does not seem to have a problem

I was trying to configure user authentication in SSH using certificate method.As u all know the usual way of authentication is using the ssh-keygen method. But i want the another method where we create a certificate key and send it to the CA, which signs it and send back etc etc.I cannot find any unique procedure in the net to configure this method.

I want to enable sshd from Internet, but I want to secure it as much as possible.Therefore, despite the fact that the service will run on a tcp port above 2000 to prevent most scans, I would like to :- First, force the use of a client certificate, to avoid brute force attack on my users/passwords- second force the use of a username/password to avoid someone having access to my system just by stealing my key..When I look at the configuration, it's possible to enable both, but one of them is sufficient to login, but I can't find how to make them both mandatory...

Having read how a private company is providing governments (and probably criminals) with a box that can listen in on SSL traffic by the use of forged CA certificates - [URL]. It turns out there's already a forged certificate in Firefox 3.6.
Go to Edit>Preferences>Advanced>Encryption>View Certificates and look for 'Equifax Secure Inc.' - You should see a proof-of-concept rogue certificate called 'MD5 Collisions Inc.' and a link to phreedom which explains the method used to generate it. That little lock doesn't necessarily mean that you're safe...

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.

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.

Occasionally my machine displays the following warning whenever left to itself for an hour or so. "www.windowsvistatestdrive.com:443 uses an invalid security certificate. The certificate expired on 09/16/2009 10:52 AM. (Error code: sec_error_expired_certificate)"
I am not trying to access this site. It is not always the same url. My machine, described below, is networked to an XP machine which recently had to be recovered after a viral attack. Since I am not usually interested I decline to use the certificate and the warning goes away.

I just upgraded from Ubuntu 8.10 to 9.04. I installed Webmin 1.470 but when I tried to run it from Firefox 3.09 I got the following message.
localhost:10000 uses an invalid security certificate. The certificate is not trusted because it is self signed. (Error code: sec_error_untrusted_issuer).
Never had this problem with Ubuntu 8.04.

Firefox 3.6.12 on Ubuntu 10.10 on my desktop computer is reporting a "this connection is untrusted" error for sites that have security certificates provided by COMODO. Yet, the same sites work fine in Firefox 3.6.x on Windows XP, or Chromium in Ubuntu. Here is the more specific message: "The certificate is not trusted because the issuer certificate is unknown.
(Error code: sec_error_unknown_issuer)" The issuer is listed as "COMODO High Assurance Secure Server CA." Here are some examples that throw this error for me:[URL]... It appears that there was some controversy with COMODO and Mozilla (due to bad behavior by COMODO) in the past, but all I can find on that indicates that this should be not an issue any longer.
Anybody with ideas?

I get an Untrusted Connection error when I visit this site to login into my GRE account, and I cannot add it as an exception, in Mozilla Firefox 4.0 on Ubuntu 11.04. When I visit the site using Chrome, I have no issues. Is this a bug in Firefox's certificate management? I'm using Ubuntu 11.04. I do not get this error in Windows' Firefox 4.0.

Girlfriend with a problem: she needs to sign up at the unemployment office in Spain. She is here in China. But for reasons unknown, she can't access the bit which she needs to. It says: 'can't set the browser' Java is enabled and so on, we read the instructions. On her windoze computer, she has a digital certificate. I copied it onto my mem-stick. When I try to copy it from my mem-stick to my Linux machine, I can't. Not even as root! The folder is called 'certificado digital' and contains two folders:
Trash.(tilde)1 and VM_Ware_Workstation They both have some kind of encrypted stuff inside. Can this certificate be installed on my machine?? Trash has 5 things, VM_Ware_Workstation has 3 things. The guy who set this up for her told her she must use Mozilla. Is a certificate only valid with a particular browser?

this is not on the master node, but rather the node that is being replicated to. The problem occurs when i query using ldapsearch or an `getent passwd` EG ldapsearch:
Code:
[root@cakeslave ~]# ldapsearch -x -b 'cn=Christian Unger,ou=People,dc=example,dc=org' -D "cn=replica,dc=example,dc=org" -H ldaps://cakeslave.example.org -w cakewalk
ldap_bind: Can't contact LDAP server (-1)
additional info: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
[code]....
The cacert.pem in /etc/ssl/certs and /etc/openldap/certificate are identical (check using md5sum). I have done an strace and found that it looks at /etc/pki/tls/cert.pem .

I am relatively new to Fedora and appreciate it is intended to be a bleeding/leading edge distribution but the continual requests to reboot the computer after updates is intrusive and seems rather odd for a unix operating system. It is often not clear to me why it is necessary when I look at the names of the items triggering the request.

I recently installed openSUSE 11.4 64Bit on my desktop computer and it is running like a breeze! I have an Intel Dual Core 2.5 and 2GB of RAM and a NVIDIA 8400GS 256MB display card. I just want to know if 2GB of system RAM would be sufficient to run a Windows XP VirtualBox with 768MB of RAM assigned to it? PS - openSUSE is still the best of the best!
