You don't.  You mount a tmpfs on top of a directory.  Once mounted, any
attempt to access that directory goes into the temporary file system
that you mounted there.  Any files that were in the directory become
inaccessible.

There are some advantages to persistent /tmp files (such as if debugging
information stays in there until you've used it).  The old idea, when it
worked, was to leave files in there and delete them a few days after
they were created, or a few days since they were last read (using a cron
job, to automate that).

Though waiting for a few days of them not being read could last forever,
in some cases.  You only have to open the /tmp directory in a file
browser, and the filebrowser will look into each file to see what they
are, and that means that they've been "read".  Likewise for anything
else that scans the directory tree, and goes through /tmp.

gnomeuimm, also seems to be long-deprecated, to the point I can't
actually find documentation for it either. gtk3mm may be the
replacement. Would guess it'd be necessary to port it to get it to
work as this stage. Why gcdmaster in particular? Reading toc files?

[389-users] Re: Can't access 398-ds Java console over https

[Tom Fallon]

Further update:

SSL is working fine it's just the console not playing ball over SSL for some 
reason. I've been using LDAP Admin (http://www.ldapadmin.org/) as an 
alternative front end which works fine.

I am still in a bit of a bind (no pun intended) as I don't have the original 
admin user setup on the LDAP server by the previous admin and only 
documentation I've found points to needing to do this via the console. Can't 
use LDAP Admin as the entry is not stored within LDAP itself.

I need this password to setup replication so could do with getting the password 
reset via another means if possible.

It looks like it just a client connection that is using AES GCM, it
hasn't got to process the ldap request yet. I think that the following
should work:

openssl s_client -connect LDAPHOSTNAME:636 -cipher ECDHE-RSA-AES256-
GCM-SHA384

Should be able to reproduce it. Else, you can wait patiently for the
crash to happen again.

Perhaps try unsetting the variables Noriko mentioned, test that the
openssl command does indeed cause a crash, then re-apply the
environment variables to see if that prevents it?

Type "env" to see your environment variables: one of them is LS_COLORS. 
 I'm guessing they are different on the two machines.

You should have an environment variable of LS_COLORS.  Check for differences or 
simply
take the settings from the system you prefer and set it in the other system.  
Normally,
you'd put that in your .bashrc if your using bash as your shell.

gcdmaster was also used to create CD text to be included in audio cd

That is the primary reason wanted the old versions of cdrdao, which used

Sorry I'm late to the thread.

Bruce, I'd love your opinion on the "SELinux for Mere Mortals" talk
from Red Hat Summit: https://www.youtube.com/watch?v=MxjenQ31b70

Disclaimer: it's a video of me, and I work for Red Hat.

I've gotten a lot of positive feedback on the video, and I hope that
it will make your decision easier. It's only about an hour, and pretty
much everyone who has watched it has said they'd use SELinux after
watching it. I am clearly biased, but I would not run any
internet-facing system without SELinux turned on. Heck, I don't run
*any* system without it.

I hope this helps!

I built this list of stuff to install from several other sites. It

initially did this for F19, but it's worked for every distro from 19

Thunderbird doesn't accept password/username

[Martin Skjöldebrand]

Hi,

Before the community sighing begins.
Yes I've double, triple and quadruple checked that the setting to the
server are correct.
And googled umpteen hits starting with Account can
not be verified - most of them telling me GMail changed their login
routine ...
No, it's not a Gmail account, it's a regular mail server.
Yes, other clients (Evolution, KMail) are able to connect and yes I've
tried accessing my mail account through webmail.

I still get "Account can not be verified - are you sure your username
or password are correct" in Thunderbird.

Any ideas before I apply to the loony bin?

You're talking about a connection to read your email as opposed to sending, 
correct?  IMAP
or POP3?

And what do you have set for "Connection Security" and "Authentication Method"?

how to automatically clean /tmp

[Walter Cazzola]

Dear Linux Experts,

I've recently passed from Fedora 20 to Fedora 23 on my laptop.

I've a separate partition for /tmp that I'm used to see it wiped out at
any reboot on my previous installation but now this is never wiped out.

This is a real partition:

  /dev/sda10   5029504   1154204   3596772  25% /tmp

whereas previously it was a tmpfs partition. I've read on the web that
after Fedora 20 the tmpfs has been dropped in favor of real partition
but I was expecting anacron/cron entry that wipe the content of the
partition at boot but my system doesn't have any.

It is also difficult to create my own anacron/cron entry because this
should take effect before the system starts and create its temp
files/sockets in there.

I'm also puzzled because I also have a couple of tmpfs partitions:

  tmpfs1633640 0   1633640   0% /run/user/989
  tmpfs163364016   1633624   1% /run/user/526

that I don't what they are for and if I can (and how) rid of them.

Probably I could add an entry like this
  tmpfs   /tmptmpfs   rw,seclabel 0 0

in /etc/fstab but this would means a waste of the space I currently have
reserved for /tmp (4Gb not much but I would prefer to use them).

So there is a way to wipe out the /tmp partition before it has been
mounted and the system creates its files and use the current partition
for it?

Thank you
Walter

GNOME Extensions for time/date and autologin

[Alex]

Hi all,

Does anyone know of a GNOME extension (fedora23 desktop) to control
the date/time in the top menubar thing to change it to 12-hr time
instead of 24-hr? Is an extension even necessary for that, or am I
missing some other ability to control that?

Is there an extension that enables autologin? I'd like to save my
password and have it login automatically, since it's only my desktop
with no other users.

Any other extensions you think are really useful you might recommend?

Thanks,
Alex

1)  shouldn't yum-fastestmirror be yum-plugin-fastestmirror?

2)  I didn't know that Google had released a 64 bit chrome.  Is there a
64 bit repo for it so it will update automatically?

Couple of points.  I don't think you can reserve a partition for the
use of a tmpfs.  It uses your RAM memory and swap space instead.

You could add /dev/sda10 as another swap partition.  Then perhaps add
the fstab entry.  However, I think systemd has a way mount /tmp as a
tmpfs without having an fstab entry.

If you want to use your partition as /tmp but have it cleaned out at
boot, check the manpage for tmpfiles.d

That's the expected behavior.  If you specify a partition during 
install, it will be used.  If you use the default layout, you'll get tmp 
on tmpfs.  There's no active wiping involved, either way.  tmpfs simply 
isn't persistent.


If you'd like to use tmpfs now, you can "systemctl enable tmp.mount" and 
comment out the /tmp item you currently have in fstab.  When you reboot, 
you should have /tmp mounted as tmpfs.


Once you've done that, you can remove the partition or LV that you're 
using for /tmp now.  Then you can resize another LV to use the free 
space or, if you're not using LVM, try to figure out how to do something 
useful with the space.

I'd like to point out that the default policy is "targeted", which means 
that it only affects the "select area of operations" where it can help 
to contain an attack.

gsettings is probably what you want.  You can see what you have set
currently with:

$ gsettings get org.gnome.desktop.interface clock-format

And, you can change it to 12-hr time with:

$ gsettings set org.gnome.desktop.interface clock-format '12h'

Hope that helps.

Mike

You might have hit a nss-softokn - processor mismatch issue.  Could you 
please try this workaround?


We would like to know setting the following environment variable(s) changes the 
behavior.
1)
Open /etc/sysconfig/dirsrv and add the following line:
export NSS_DISABLE_HW_GCM=1
Restart the Directory Server.
Does the LDAP/TLS request crash the server?
2)
If the server still crashes, add another variable to /etc/sysconfig/dirsrv:
export NSS_DISABLE_HW_AES=1
Restart the Directory Server.
Does the LDAP/TLS request crash the server?

Hello,
the first variable is set. Unfortunately I can not reproduce the
request, since I do not know it;(

Do you mean stack traces?  If you have stack traces just paste them into 
the email.  I don't think error/access logs alone will provide any 
useful information without a stacktrace.

It's fairly clear you've understood nothing I said. Pointless to continue.
