prepping to teach a 5-day CompTIA linux+ course next week with CompTIA-supplied courseware and, given that it was my choice, i chose to set up the classroom with centos 7.4 on all the student systems since i assume most students are there to learn sysadmin and that's the most likely platform they'll have when they get back to work. also, most students are taking this course to prep for the

Hey Everyone, I am running the new Dovecot 2.0 RC2. When I try to run 'doveadm quota recalc -A' I just get the usage info for doveadm. Running 'doveadm help quota' gives me the man page for the quota command, and I follow the man page examples as is. Is this feature not implemented yet? Or am I doing something wrong? I know quota is a "plugin" for the doveadm program,

I'm trying to get authentication to work without PAM and just use the standard shadow and passwd files. auth default { userdb passwd { } passdb shadow { } } This seems to be valid code to use /etc/passwd and /etc/shadow. My linux distro is using Salted MD5. Though Dovecot keeps telling me that authentication failed. It doesn't give me any error messages regarding the config. Any

I am testing out the new Dovecot 1.2.beta1 software. I am getting reports from people using POP3 that it randomly drops connections. Looking at the log file I see that the POP3 process they were connecting to panics and dumps a Raw bactrace. Below is a copy of the logs (IP addresses striped for security): dovecot: Feb 21 13:10:45 Info: auth(default): passwd-file(janna at jantics.com,x.x.x.x):

Hello. I've just spent some time figuring out why on my RedHat ES server samba allowed me to connect, browse directories, but as soon as .exe was in the dir it would freeze. I couldn't open text files or anything else. It turns out that the Redhat kernel does not play well with 'sendfile' functionality. so I added: use sendfile = no and I'm back in the game. Anyone could

I am setting up VM off Metaswitch due to a problem with Metaswitch VM. I have a couple days to prove this works and I need a little assist please. I am using TRIXBOX 2.6.2.5 and have the Meta SIP trunk up. I have extensions built that can talk to each other. I took a trace on the TRIXBOX that shows when I dial my test phone on Metaswitch it goes to VM after a couple rings and the call goes to my

i'm sure there's a simple answer to this -- i already understand that newer kernels than the ones shipped with the official release aren't officially supported but there is the elrepo kernel repository here: http://elrepo.org/linux/kernel/el7/x86_64/RPMS/ with a mixture of long-term (lt) and mainline (ml) kernels. i assume that the mainline kernels pretty closely track the latest

i'm just curious -- how many people here are using ACLs as a regular and significant part of their sys admin? rday -- ======================================================================== Robert P.

does anyone here have pointers or access to courseware that could be used to teach centos (5.4, i believe)? publicly-available, free C/W would, of course, be ideal, but if you have some decent training manuals that you're willing to license on a per-manual basis, i'm still willing to chat. rday -- ======================================================================== Robert P.

NEWBIE alert: i'm a linux person, not an asterisk person so i'm certainly capable of handling any linux-flavoured solution you can suggest. here's a note i got from a local company i know (some proper names removed): ===== start ===== Now and again our ISP goes down and when it does give us a hicup, the Asterisk system shuts down (not very forgiving). When it shuts down our phone

again, from here: http://wiki.centos.org/FAQ/CentOS5 regarding a newer version of PHP, a number of PHP experts that i know of suggest that, if you truly need an up-to-date version of PHP, you should: rpm -ivh http://rpms/famillecollet.com/enterprise/remi-release-5.rpm while remi collet's repo isn't official, it's accepted by numerous developers as a reliable source of newer PHP

is it possible to set up NFS on centos 5.5 so that it uses *only* version 4? i tried this not that long ago on fedora and was surprised to see a complaint when i tried to start the server and was told that i was missing required functionality of NFSv1, or something equally weird. i'll check the /etc/init.d/nfs script, but i think what got me into trouble was trying to use the entire set of

just to fix obvious and trivial typoes that i'm running across, like on this page: http://wiki.centos.org/FAQ/CentOS5 "notwithin" "you did not chose to reserve" simple stuff like that. anything more involved, i'll post. rday -- ======================================================================== Robert P. J. Day Waterloo,

absolutely serious question -- i appreciate that it's important to still document how things are done in centos 4, but i have precisely zero interest in that. given how long centos 5 has been out, and that centos 6 is not that far down the road given the alleged release schedule for RHEL 6 (rumoured end of year), i plan on investing my time in centos 5 and 6 exclusively. so while i'm

here: http://wiki.centos.org/HowTos/Network/SecuringSSH the recipe for how to copy your id_rsa.pub file to a remote system is given as: "Copy the public key (id_rsa.pub) to the server and install it to the authorized_keys list: $ cat id_rsa.pub >> ~/.ssh/authorized_keys" i suspect it would be better if that were rewritten in terms of using ssh-copy-id, just to be simpler and

i just registered for a centos wiki account, and was wondering if this gives me edit capability. i'm prepping for the first of a number of RHEL/centos basic admin courses and currently working my way thru the wiki, collecting neat tricks and ideas and, occasionally, i'll stumble over typoes -- some minor, some not so much. for instance, here:

it's been a while since i've played with filesystem encryption so, on centos 5.4 (and other linux distros), is dm-crypt/LUKS considered to be the state of the art WRT encryption? i remember other solutions like loop-aes and others, but what's considered the gold standard these days? rday -- ======================================================================== Robert P.
