Does anyone know how to get procmail and dovecot to play happily together with
mboxes? I'm on Centos 6.5, fully patched.
I'm getting tons of lock timeouts which is killing performance.
I tried using dovecot's lda from procmail, which prompted many adjustments to
selinux, which I managed, but it still gives permission problems, and I haven't
succeeded in getting it to deliver mail.
Any guesses at all would be useful.
thanks,
-chuck

Just wondering if you had the chance of testing the network speed with
iperf from host to host yet?
This is like the first thing to do while doing a full debug upside-down.
No matter what disks you have but note that each and one of them has a
maximum IOps limit which sometimes you can hit in a way.
as already suggested by others in the past you can use a binary search
dividing the issue one part at a time network.. disk.. controller..
driver.. software(since the software is proven to work).…

Hi,
I'm a bit confused regarding the connection of a Mac OS X system to the
app store by the app store client.
Squid is configured using ncsa_auth and I can access https and http
websites without a problem.
But the app store app is not logging in. I do get
==> /var/log/squid/cache.log <==
2014/06/11 13:23:10| The request CONNECT p12-buy.itunes.apple.com:443 is
DENIED, because it matched 'ncsa_users'
2014/06/11 13:23:10| The reply for CONNECT p12-buy.itunes.apple.com:443

2014/06/11 13:23:10| The request CONNECT p12-buy.itunes.apple.com:443 is

in my squid logfile.
Any hints or suggestions? Regards . Götz

I have googled, read the man page, and such.
What I am trying to do is install applications to a NFS mounted drive,
where the libraries and everything are locally installed on that
filesystem so that it is portable across servers (I have over 100
servers which each need specific applications installed via yum and we
do not want to install 100 copies).
We tried the yum relocate and it was not available on Centos6.4
and
yum --nogpgcheck localinstall R-3.1.0-5.el6.x86_64
I want the …
[View More]binaries and all dependencies in the application filesystem
which is remote mounted on all servers.
Thanks,

I have a question about SSD respecting security. Recently I have been
investigating sanitizing these devices, together with 'smart-phones, tablets
and pads which use flash memory …
[View More]persistent storage. Not to mention the
ubiquitous USB 'memory stick'. I have come to the rather unsettling
conclusion that it is effectively impossible to 'sanitize' these things short
of complete and utter physical destruction, preferably by incineration. Is
this in fact the case?

Let's see, how many grad students did the first digital computer need to
replace the burned-out tubes? Was it about that many?
But I agree, he does win the 'Net for today. I propose we award him one

I started using chrome on the RHEL7 beta after some firefox hangs -
but maybe this behavior is generic. I have the system 'network
settings/network proxy' set to use squid on another host for
connections out of the private range we use. This proxy requires
authentication so I can always tell the first time a browser uses it.
However, I can start a chrome connection to gmail and it just goes
direct (which happens to work, I just prefer the proxy which will use
a different outbound route). …
[View More] If I go to any non-google site, it uses
the proxy and will pop up the expected authentication dialog on the
first connection. Does anyone know (a) why it bypasses the proxy
when going to a google site, (b) why it doesn't have its own internal
proxy settings, or (c) how to fix it?

Hey all,
We have the following set in /etc/profile :
umask 0002
so that it will affect all users. That should create all files as 664 and
all directories as 775 if I'm not mistaken.
Well I logged into the machine after this was set and just created a file
as one of the users who complained about permissions settings on files. And
this is what I saw:
[user1@qa_host ~]$ ls -l test_qa
-rw-r--r-- 1 user1 domain^users 0 Jun 11 10:08 test_qa
I even tried logging out and logging in again just …
[View More]to be sure. I still got
the same result.
So my question is why would the file not have the permissions specified by
the umask command in /etc/profile ? I really need this to work for the
users.
Any helps or clues would be great!
Thanks
Tim

I decided that the next time I reformatted my main desktop computer (this one) I would have a ssd installed in it to use for the boot drive. Now that Centos 7 is on the horizon, I'm thinking that the time is approaching when I'll want to do that.
The last time I set up a computer with a ssd in it, that was the only drive that it had. I changed issue_discards=0 to issue_discards=1 into the /etc/lvm/lvm.conf file, set up cron to run fstrim on that drive on a weekly basis, and that was it.
…
[View More]Since this next setup will have both a ssd and a regular hard drive in it, is there some way that I should specify that issue_discards=1 applies only to the ssd or does that matter? I see that the explanation in the lvm.conf file says "If set to 1, discards will only be issued if both the storage and kernel provide support." so I'm left with the impression that the issue_discards setting won't affect a regular hard drive even if it is set to 1.
