[opensuse-factory] Boot speed and services
There's been talk about improving boot speed and stopping unnecessary services from running by default. I believe postfix, sshd and AppArmor are not necessary on most installations, I certainly always disable them. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

AppArmor has no running daemon (it uses auditd for logging), it is mostly a kernel module.

It loads the profiles on boot. But: I prefer security over saving a second of boot time ;-)
(it uses auditd for logging), it is mostly a kernel module.
Just curious: What's the advantage of using auditd compared with logging to syslog-ng? (I see only a disadvantage right now: auditd doesn't have human-readable timestamps in the log :-/ ) Regards, Christian Boltz --

Maybe you should unplug your internet connection then ;-) It's overkill for home desktop users imo, which make up the majority of users I expect. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

It might be overkill at present time, but... See what's happening with windows... One of my colleges in the office installed a windows box less than a week ago, to try to reproduce an issue that his customers had. He then left it overnight (the machine is sitting behind a firewall and the only access to the internet will be NATed) and when he came back the next day, he had viruses all over the place. All he did was to install the box. He didn't use it at all. But viruses (worms, whatever) still manage to get in there... So, as a security measure, always take the necessary precautions. If we're not targeted today, we might be tomorrow!

No, this was in his own vmware session and nobody would have used that machine.

I hope you have the latest anti-virus stuff and all the latest patches installed on there.

No, this was a virus. I can find out exactly which virus it was if you want to. The point is, sad but true, that if you install a windows box and don't apply the latest patches straight away, together with an anti-virus program, you will get viruses on there without even browsing the internet!

That might be. A worm, for instance. If there are other machines infected in the same intranet, he could easily be exposed. I think xp has some kind of firewall, maybe it was not active.

Maybe an idea is to add a list of not essential services at install time, where the user can decide to disable them.

I have said many times in many forums that I thought that there needs to be an effort to reduce the "kitchen sink" approach of SuSE\OpenSuSE , it is starting to appear with build patterns but needs more work .i.e. detailed view in the installer for advanced\expert users to add those "services" they expressly need. I hope that the Devs see this as a good thing too! OpenSuse is the best , but it doesn't need to keep installing multiples of everything, i.e. Krita and Gimp , for someone who wants just to check e-mail. lighter, faster and less complicated has been my chant for three years. I am still waiting for http://en.opensuse.org/SLICK to come into being. I too have a box of P 1 laptops going into the trash bin. they make great thin clients so i still use them but time is running out because they need a wire for that job. If the education environments of the world are to have cheap computers they are going to have small HD's and limited ram so working to reduce the installation minimum is of high priority.

Forget about harddisks. Still trying installing SuSE on an usb-pendrive, and also have some storage-space left. Hopes that slick-project would fit on a Kobil-mIDentity stick or an Etoken-flash....

My box of running P1 350MHZ laptops have as a max 128 mg and a 6 gig drive. I'm sure that it would be cheaper to build a HD with one platter that is a total of 10-20 gig than to build a 6 platter 120g HD. My laptop is a 2\3 year old Centrino 1.5ghz with 2 gig of ram(256 default), 40g HD and a 32mg video card. if IBM\Lenovo saw that this laptop were going to be viable for another 5-10 years they wouldn't need to push to discontinue this one, but with 512mg video requirements and operating systems that come on 5 cd's or a DVD on the market, my Motherboard is completely useless to them. But Lenovo could sell the Manufacturing tools and rights to this MB to some builder to sell as a Linux platform and still make LOADS of cash, unless Linux adopts those same requirements as a mandatory installation environment (which seems to be on it's way). How does Education get to keep up? What if those P1 tools still exist somewhere? or the PII's or etc.....why build a special 100.00 laptop when continuing to produce this system until its cost of manufacturing drive it down to 100$, unless there is no distro to run on it? Hell Novell could buy this MB from IBM\Lenovo and make a killing! it is fully SLED compatible! I'm on 10.2 now.

I don't know why postfix is needed on most machines, but sshd is useful to help remotely people that are beginners.

Your argument is pretty weak as we default to firewall enabled, so it's pretty hard to get to the ssh port ;) Greetings, Stephan -- SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

I think this whole discussion is greatly relative to the difference server/desktop.

Yes, having an MTA which can deliver local email is absolutely essential. cron, smartmontools, fetchmail(!), you name it. What would be a very good idea(TM) is if the MTA in its default configuration was prevented from delivering email to other than localhost or one of localhost's domain aliases. I tried this with postfix and found that it's not possible, though there are 2 drastic and not very nice workarounds for this problem.

It hasn't been removed: I have it (10.2) However, notice that that line does not prevent mail from being _sent_ to outside. It just prevents mail from being sent to that system using smtp (ie, postfix or sendmail). - -- Cheers, Carlos E.

But you're right, I didn't read well the message and it was about blocking delivery to external hosts. I could be wrong but I think that, to configure the machine for local only delivery of local mail, i.e to receive in a local account on the local machine the mail sent from the machine itself, you only have to modify the following parameters in /etc/postfix/main.cf:
myhostname = localhost mydomain = localdomain inet_interfaces = localhost mydestination = $myhostname, localhost.$mydomain, localhost mynetworks_style = host
I have: mydestination = $myhostname, localhost.$mydomain, localhost mydomain = nimrodel.valinor myhostname = nimrodel.valinor mynetworks = 127.0.0.0/8 [::1/128] mynetworks_style = host inet_interfaces = $myhostname, localhost which is very similar and I can send - as you can check looking at this email header ;-) I'm not sure if the small diferences are that crucial :-? - -- Cheers, Carlos E.

There used to be the following lines in /etc/sysconfig/mail:
## Type: yesno ## Default: no ## Config: postfix # # Set this to "yes" if mail from remote should be accepted # this is necessary for any mail server. # If set to "no" or empty then only mail from localhost # will be accepted. # SMTPD_LISTEN_REMOTE="no"
This prevents sendmail/postfix from accepting mail for delivery from interfaces other than localhost. Note that once mail has been accepted for delivery, there is no restriction as where this mail will be delivered to. This is a useless restriction for preventing any local users from sending mail to anywhere on the internet. Note also that mail can be given to sendmail/postfix for delivery by anyone calling /usr/sbin/sendmail.
Why have they been removed?
They haven't.

I think this whole discussion is greatly relative to the difference server/desktop.
Yep, definitely.
I couldn't image a server without sshd, but on a desktop? most users of thunderbird and seamonkey not even know there is an other mailbox :-)
I find it useful to use fish:// between two desktops - I have two office locations that I occasionally swap between.
servers are not stopped, so the boot time is not very important :-)

It's a KDE KIOSLAVE. In almost all KDE applications you can access remote (file) systems which have sshd installed just by using the fish:// protocol.

Or sftp:// for that purpose (why go through the fish hack if you can use
sftp -- except when sftp is explicitly disabled on the ssh server)

There doesn't seem to be any difference in functionality? /Per Jessen, Zürich -- ENIDAN Technologies GmbH - managed email-security.

Your argument is pretty weak as we default to firewall enabled, so it's pretty hard to get to the ssh port ;)
Ok, I didn't remeber what is the default behavior of the firewall. But in that case (ssh port is closed) it is really not needed to run it at startup for every system. Andras -- Quanta Plus developer - http://quanta.kdewebdev.org K Desktop Environment - http://www.kde.org

I believe postfix, sshd and AppArmor are not necessary on most installations, I certainly always disable them.
I'm sure it varies a lot, but none of my systems would do very well without postfix and sshd. Using Apparmor or not is a security issue. /Per Jessen, Zürich -- ENIDAN Technologies GmbH - managed email-security.
