I have a standard home set-up for my Ubuntu OS, and I would like to know whether its possible to cut out the repetitive prompts to enter the password, as when you connect to the internet or access files on a partition that's not home, or install new software.
View 1 RepliesIt's been awhile since I've been on here. I suppose that can be considered a good thing, since I made the completely transfer to Ubuntu three months ago and everything's been running completely smoothly. Anyway, security is a pretty big thing to me. I usually change the root password, take sudo off (and default gksu, not gksudo), encrypt my hard drives, etc... One thing I also do is create a separate password for my login keyring. I don't mind having to enter one extra password at login, but it started prompting two times, and now three. It's the same password every time, so my question is..
View 4 Replies View RelatedI know it's safer not to block the request for a password that unblocks the keyring but I'm desperate.
The more I use ubuntu more times I'm requested to provide the keyring password. Now, this time, i've typed 7 times!
is there a way to limit this nighmare. Every time I bootup i got tired.
I have a Kerberos/LDAP/OpenAFS server running on Debian lenny, set up according to Davor Ocelic's excellent guide here (url). SSHd has ben configured to use GSSAPI auth and the clients have been configured to pass auth tokens through to the server.
My clients are all Ubuntu 9.10 x86 fully patched. On the clients, OpenAFS has been compiled and installed as a kernel module and git 1.6.6 has been compiled from source and installed. Otherwise, all software is stock Ubuntu repository-ware.
The setup is working fine as long as I connect to the primary server using its hostname:
peter@client01:~$ ssh nana
<connection goes through seamlessly without prompting>
peter@nana:~$
If I try to connect via a DNS alias (actually a second CNAME record), I get:
peter@client01:~$ ssh git1
peter@git1's password:
<connection completes>
peter@nana:~$
I need both passwordless auth and the DNS alias working, as it's internal policy that user connections are only ever made to service names, not real hostnames.
I have tried adding a second host principal to Kerberos for the alias (git1.darling.local) in addition to the host principal for the hostname (nana.darling.local).
If I turn off PasswordAuthentication in sshd_config, then "ssh git1" doesn't even fall through to passwords; it just denies logins. So it looks like it's not even using GSSAPI for the DNS alias.
So:
1) Is what I want even possible? I can't find anything that indicates that there's anything odd about DNS aliases such that this should happen.
2) Which config files should I post to help debug this? There's a lot and I didn't want to start blarfing them here if they aren't helpful.
everytime i try to vnc to my box, it pops up the keyring authentication, which is obviously a huge problem when logging in remotely.how do i change my keyring password to match my login password?

I need to limit the number of ssh connections a user has. All the users are using tunnel only so their shell is set to /sbin/nologin The logins do not open a shell they just create the tunnel so /etc/security/limits.conf has no effect on them at all.
I tried setting 'MaxSessions 1' in sshd_config but either that doesn't not do what I expect it to or it plain does not work as even with a normal user I was able to open an unlimited number of sessions. I need a good secure way to limit each user to 1 ssh session without them having a shell but Im unable to find a solution.
I'm looking for a solution for sendmail to limit the number of emails send per miniute per IP. For example all my local computer user with ip 192.x.x.x need to able to send 10 emails/minite (emails, not connections!. The rest of the world can send for example 200 emails/minute to the mailserver. If the amount of emails per minute is exceeded, sendmail needs to block receiving emails from the spesific IP. I want to do this to stop spaming from my local network. Is it possible?

I just reinstalled ubuntu lucid after accidentally damaging it, And I used all the same passwords and user names as before, I can login fine, and I can do sudo commands, but the gnome keyring wont accept my password, I tried changing my password using Applications>accessories>Passwords and encryption but that didn't work. How can I fix this so that keyring will accept my password, I need it to save my wireless router password.

When I installed Ubuntu (Lucid) on my new computer, As well as the login password I was asked for a keyring password. I gave one, but I am not sure exactly why I need this password. It seems that it was required to let me access the wifi - even though this has its own security code. I found I could stop the system asking for it every time I tried to connect to the internet using wifi by checking a button in the network setup, but when I registered for Ubuntu One, I was again asked for it - twice, once when I registered and again when I set up Tomboy notes sync. Now I get asked for it again every time I switch on.
I would like to know why the keyring passwords are needed in addition to the login password for a single user computer, which mine is and also how I can stop it asking for this password when I switch the computer on. One suggestion I have seen is to make the keyring password the same as my login password. If that is the case, then how do I change the keyring password?
I just changed my password now every time I start my computer the keyring wants my old password and it keeps doing weird things even after I type it in. Like Ubuntu will say No keyring found or something to that effect anyway.

I am running Ubuntu 9.10. When I open Evolution, it prompts me for a password to the default keyring. I am not sure what this is, but I would like to not have to do this. I looked around in Evolution and did not see a way to have this password entered automatically. I searched this forum and it found no results. So I don't know if my problem is unique or not.
View 3 Replies View RelatedI know, I know, its a security feature. That doesn't make it any less annoying. I find the constant asking for my password to be every bit as irritating as Windows's UAC. When I want to use the terminal, or when I want to download something, I don't want to have to enter my password every time. I don't care that someone could theoretically do something to my computer in some way. I managed to stay out of harms way in windows with UAC off, I'm sure I can do it in ubuntu without the constant nagging of the password prompts. Its annoying and I am tired of dealing with it. Anyone know how to turn it off? I am really not looking for reasons to leave it on. Its the same with UAC: Yeah, it can keep you out of trouble. No, I don't want it on.

I just installed Ubuntu last night on a partition, and so far..There is one thing that may be a deal-breaker for me though: It seems that I am always prompted for a password!!!! When I first start my machine up...PASSWORD! O-K, once a day wouldn't be so bad...but if I let my display turn off while I'm away from the 'puter...I come back, and...PASSWORD?! Every time I try to do anything on the system....PASSWORD?!
I did a few things that I thought might solve the problem- I checked some boxes here and there, like "automatically log on" and made myself an administrator....but no matter what I do, I'm plagued by the password prompt 600 times a day and i can't take it!!!
Is there any way to stop this nonsense? This is WORSE than Windows UAC crapola!! (at least with that, you just have to click a button)- As much as I am loving Ubuntu....if there is no way to disable this password nonsense, I'm afraid I'll be heading back to Vista. I'm the only person who uses my computer (Although I think my dogs were playing on it while i was out fixing the tractor today...)- so I just need to know if there's a way to get rid of all this password-protected stuff?
Was just wondering if there was a way to disable the password prompts that pop open every time I try to install something. Is there a way to do that?
