3.13 Kernel

[David Baron]

Is it just my very subjective impression or are these significantly faster than 
3.12??

Maybe, certainly my guesses as to the cause are similar... the tarball'd
be tricky (debsums).

*If* the package was legitimately installed - then it's removal would
ease Ha's concern. Though without understanding how it happened it's no
less likely to happen again.

I haven't seen the result of checking the selections with dpkg. There
are a couple of scenarios where the user/operator can damage the dpkg
database - I'm not familiar with all of them.

Unfortunately the OP's editing combined with my free time limitations
mean I'm not sure who said what - so that comment wasn't aimed at any
particular participant in the thread. It's a convoluted thread and at
present there's still three recent posts I haven't read.

I'd hate to hold anyone responsible for their memory - AFAIK no one can
remember what they don't remember (this is why we take notes and run
script) - I can only assume their memory is complete. With other areas a
guess/"instinct" may be good enough - with security I prefer proof.
Even if they didn't specifically install open-vm-tools it could well
have been a dependency

Hopefully you realise that should take quite a while to run, and you
correctly mounted etc for your check...

Looking at those files makes me think of a possible installation error:
that one or more partitions on the old install were used and mounted
"without reformatting" for the new install.

Is there a timestamp check that could be performed (install time/date
for the file, rather than the datetime that ls -l shows?

There's a difference, indeed.

My guess is that this situation is the result of invoking:
dpkg -X *deb /

or, simply unpacking a tarball into /.
But your guess is as good as mine.

What I cannot understand is how exactly removing a package would fix
this issue if both apt and dpkg claim that the package is not installed.

If you browse this part of thread up, you'll see that OP did checked
the root filesystem with debsums, and debsums haven't found anything.
Therefore I agree that it's unlikely that vmtoolsd is a malware.

Agreed. That's why I wrote earlier that no reinstall is necessary.

Yet, there is another thing - OP claims that he didn't install anything
like this.

Please note the difference between *are/is* installed, and *were* installed.

I would expect dpkg -S to fail if those packages had been wrongly
removed (corrupting dpkg database) but the pam and man files are
extremely unlikely to be the result of malware. The OP never responded
to my query about the other files that would have been installed - or
checked the installation history with dpkg --get-selections (it won't
show if purge was run, but then, those files would likely not be left).

It is possible[*1] vmtoolsd is a trojan - though that scenario means the
rest of it's expected files would likely be there (and dpkg -S would
find it) - an md5sum is a simple way to check.
Simply re-installing a system because some one "suspects" a security
breach - will zero evidence to support the suspicion, is not a good
idea. By all mean re-install from a known clean source - but first check
to see if the installation was legitimate (check package selections
status), check "suspect" file/s. Otherwise it confirms nothing and do
even less to help detect and defend against real malware.

Always test when security is in doubt - but it's probably not a good
idea to rule out user error.

[*1] the first reported case.

Kind regards

This:

> dpkg-query: no path found matching pattern /usr/bin/vmtoolsd

equals to 'no package owns /usr/bin/vmtoolsd'.
'open-vm-tools' package owns /usr/bin/vmtoolsd file.

If open-vm-tools is installed - 'dpkg -S' would find it.

I've got nothing.
I'm guessing you wouldn't have Tracker installed:-

Nautilus? Perhaps they use the hooks from the gvfs-metadata?

I run XFCE, and I have the "Mount Plugin" applet, to assist
unmounting, but it seems to have the same problem.

Unless, most likely, you've since removed the packages (and open-vm-dkms
and zerofree)

There's an easy test:-
$ dpkg --get-selections | grep 'zerofree\|open-vm'

 dpkg --search ${filename}

Woops! No it won't. Apologies to whoever suggested that (I didn't strip
the attributions.)  --search is the long-hand for -S.
It *will* search for a file installed as part of a package and the
following should happen if openvm-tools and openvm-toolbox have been
installed and removed at some point (but not purged):-
$ dpkg -S vmtoolsd
open-vm-tools: /etc/pam.d/vmtoolsd

Is that the process that shows how much space is available in the GNOME
file manager widget?
You don't have your file manager attempting to display the contents of a
drive you simultaneously want to unmount (and therefore not display, or
it's free space) - do you?

open files/ forcing dismount

[Zenaan Harkness]

One long term "non-easy" issue that keeps coming up a few times a
year, is attempting to dismount an external drive/usb stick and this
failing due to a file being opened.

lsof is a good start, and sometimes advised in the error message with
some other command.

However, what ends up the case is gvfs has it's greedy fingers stuck
right up the drive and refuses to let go!

There _ought_ be a simple force dismount option. There ought be one
command (I know, let's say "umount") that achieves this, optionally

Does such a thing exist?

umount: /media/tmp: device is busy.

 the device is found by lsof(8) or fuser(1))

$ grep wlan /etc/udev/rules.d/70-persistent-net.rules
if it's there (I don't have one I can check at present) then edit the
entry matching the correct MAC address and change it's name from wlanN
to wlan0, then remove the other wlanN lines. You'll need to be root to
edit the file.

Yes. ifup only does something if the net device is not up already.
Instead try:-

You set it to manual (so it's off somewhere reading the manual?) ;p

It's there, but you haven't specified it e.g.:-
# iwconfig wlan0
which is why iwconfig it's trying all of the *configured* network devices.

man interfaces 
"The manual Method
   This method may be used to define interfaces for which *no*
configuration is done by default. Such interfaces can be configured
manually by means of up and down commands or /etc/net‐work/if-*.d scripts."

What I take that to mean is - that unless you have something in
/etc/network/if-*.d then the if up/down commands need to be qualified.
.i.e issuing:-
# ifup wlan0
is interpreted as "do nothing to wlan0". Compare that to "ifup eth1"
which is interpreted as "ifup eth1 "

Am I missing part of the thread?  Where did the OP check to see if
open-vm-tools and open-vm-toolbox were installed. I see where to OP

Yes - you are paranoid. There is no conspiracy. Those files were
installed by the operator/user/sysadmin.
So relax. :)

If you want to remove them:-
# apt-get remove open-vm-tools open-vm-toolbox

It's difficult to tell who you're quoting as you've stripped all the
attributions from the post.
You'll also find you have:-
/etc/vmware-tools/xautostart.conf
/etc/vmware-tools/poweroff-vm-default
/etc/vmware-tools/poweron-vm-default
/etc/vmware-tools/resume-vm-default
/etc/vmware-tools/scripts/vmware/network
/etc/vmware-tools/statechange.subr
/etc/vmware-tools/suspend-vm-default
/etc/vmware-tools/tools.conf
/etc/vmware-tools/vm-support


 This rather highlights why I like Arch's package manager (Pacman.) more
 than APT. Pacman features a command (pacman -Qo ) that explicitly
 checks a file you specify for package ownership.
>>>
>>> dpkg --search ${filename}

Will search for the installed *package* name
"vmtoolsd" is *not* the package name
"open-vm-tools" is

So you 'could':-
dpkg --search open-vm-tools


It's unlikely to be an attempted backdoor - more likely it was simply
unwittingly installed as part of something else e.g. open-vm-tools-dev
Anyone/thing capable of installing software requires root - while it's
possible they/it could achieve that and still be dumb enough not hide
that file, it's very unlikely.
NOTE: vmtoolsd is *not* a back door, or part of any rootkit.

To see if the package was legitimately installed:-
dpkg --get-selections | grep open-vm

In your case you'll find *you've* installed:-
open-vm-tools and open-vm-toolbox

and:-

man open-vm-tools  # unlikely even a script kiddie'd leave the
documentation for you don't you think? :)

When are doing a one-shot (ie/or just testing), then I always add the
"-d" option to stop dhclient from backgrounding as a daemon - this way
it runs in the foreground, and I can kill it with a CTRL-C at any
stage - having to ps aux|grep dh then kill the appropriate IP has been
a source of frustration in the past.

I think you mean "auto lo eth0". I separate the lines, so leave the
"auto lo" line as it is and add a new line (if wanted):
auto eth0

> iiface eth0 dhcp

Looks like you have a bit of a thing for this 'i' char :)

Or in multiple "auto" lines, to belabour the point.

If you do not want this process to take precedence, why did you choose
such a low niceness to other processes? Shouldn't you have chosen
something above 10 or at least above 0?

You can force or change the order of the nameservers. /etc/resolv.conf
even has an option "rotate" to do round-robin among the listed
nameservers. What you cannot do is expect the current resolver library to :
- ask a given nameserver for a given type of queries (e.g. "external
names"), and another nameserver for another given type of queries (e.g.
"internal names") ;
- ask the next nameserver if the previous nameserver replied that the
requested name does not exist or does not have a resource record for the
requested type (aka negative answer).

Why then are you messing with the router's nameserver ?

If you need to resolve both internal and external names, I suggest that
you query only the Debian nameserver and configure it to reply to
recursive queries, either by itself or by forwarding them to the
router's nameserver.

According to the manpage it is not necessary to restart the daemon, so 
this should not fix your problem. How about you attach your crontab and 
the relevant parts from syslog? Also check if you have anacron 
installed.

I'm trying to configure a machine with two network cards to share

auto eth1

The card eth0 is used as gateway on the internal network with static IP
192.168.0.1 and eth1 is connected to the B-890 -53 Huawei modem.

But the modem do not send an IP during initialization.

The IP of modem is 192.168.1.1.

The modem sends the IP address (192.168.0.4) to my laptop by wifi
without problems.

Any suggestions of what I should check?

   

I'm afraid that I don't understand the problem.  Is this a traditional
async dial-up modem?  If so, I would expect it to be configured with
ppp,
its interface name would be ppp0, and it would not be listed in
/etc/network/interfaces at all.  I don't get it.


 

I'm guessing it's a cdc_ether device - probably running a web and dn
server at 192.168.0.100.  Hopefully the OP will correct my assumption
(Vendor and Product codes from dmesg?).
I'm not familiar with that particular model - but I've had to hack Linux
support for the chipset either side of it (model number).


Kind regards



   

Dear Scot and Stephen,

I am using this model of modem:

http://www.4glterouter.de/huawei-b890-4g-lte-smart-hub.html
 

Thanks - yes it's the chipset I was expecting.

   

I just tested on another machine and the modem supplied the IP to my
laptop via wireless and IP to a computer (with 1 NIC) via ethernet
without problem.
 

Yes.

   

Tomorrow I'll change the network card (of the machine with 2 NICs) and
test again to see if the problem is the network card.
 


OK - I misunderstood - I didn't realise you had a second card installed
and assumed you'd just noticed the USB modem cable is seen as a NIC, or
that networkmanager had autoconfigured it for you (it should, if you
have a recent version of usb-modeswitch installed).
You don't need the 2nd network card unless you want to duplicate the
routing functionality build into your modem/hub/router. Just connect the
modem to that computer with the USB cable. Make sure you have
usb_modeswitch installed and add the extra line I suggest (the gateway
stanza).

The modem should then be seen as /dev/eth1 by Debian and will be used as
the gateway for your internet. You'll find that resolv.conf will
automagically use the modem as the nameserver .i.e. /etc/resolv.conf
will contain:-
nameserver 192.18.1.1

You don't need to add netmask and broadcast stanzas to
/etc/network/interfaces, you do need to change auto to hot-plug for the
modem (yes it's USB but the system will see it as an eth device).

Any other devices you connect to the modem should automagically (via
DHCP) do the same - and by default will all be able to communicate with
each other.

NOTE: the route output I quoted (in the previous post) is from a box
connected to a similar Huwaei modem in the same situation.

/etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
allow-hotplug eth0
iface eth0 inet static
 address 192.168.0.6
 netmask 255.255.255.0
 gateway 192.168.1.1
 # dns-* options are implemented by the resolvconf package, if
installed

allow-hotplug eth1
iface eth1 inet dhcp
 # you could make this static, but more typing would be involved


NOTE: network and broadcast stanzas are optional

   

Thanks for your attention,
Markos


 

Kind regards


   
Dear Scott Ferguson, Stephen Powell, Dan Purgert, Andrei POPESCU, Pascal 
Hambourg, Rod James Bio and Rob Owens,


Thanks for your comments.

As I said, I tested the modem at home, and it worked well.

I imagine that the initial problem was related to the network adapter.

The next day I changed the network card and realized the following:

When I changed the network card the system started to assign the address 
to eth2 the new card and the modem sent the IP address for this card (eth2).


Despite that the /etc/network/interfaces is:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0

auto eth1
iface eth1 inet dhcp


Then I replace the second NIC by another one and again the system 
assigned the number "eth3" for this new card.


And also the modem sent the IP number OK.

Every time I change the card the system increment the number to the 
interface: eth2, eth3 etc..


I searched on the Web and

Try execute "dhclient xxx0 IP-of-Server" as root. For example

dhclient eth0 192.168.1.1 

or 

dhclient wlan0 192.168.1.1
 you 
You can request each interface as needed.

If you want it automatically at boot, edit /etc/network/interfaces.

The syntax i.e. for eth0 is 

auto io eth0

iiface eth0 dhcp

If you do so, each command "/etc/network/interfaces restart" let you request 
an IP from the dhcp-server. All interfaces named in the "auto"-line are 
initialized new then.

Hope this helps.

Good luck!

Hans

very slow Xorg and/or bash

[Morel Bérenger]

Hello.

Since few days, say 4 or 5, my netbook is *really* slow when a terminal
starts. After taking a look with top, it seems that it's bash itself which
is the problem: it makes the terminal freezing for at least 15s on login,
and almost the same when using auto-completion.

There is also xorg, which uses constantly at least 10% of the CPU, if I
trust top ( at least, means that it is the minimal value ).

I have no idea about how to find the origin of the problem, this is why I
am not giving any real hint or suppositions.
I do not remember having updated anything particular ( but no doubt that I
did, otherwise I could not have such kind of constant slowness ).

I am using a testing/unstable/experimental debian, no DE.
wheezy's packages have priority 900, unstable ones only 200, except for
compilers ( Package: clang* gcc* g++* cpp* libgfortran* )
Running services are currently:

Any idea about the problem? Or at least any idea about what to look for to
have one?
I suspect some bash script, but the slowness is also with root, and I did
not changed anything by hand that could affect root since at least 2
weeks.

   apt-cache rdepends --no-breaks open-vm-tools

gives

   Reverse Depends:
 open-vm-tools-dbg
 open-vm-toolbox
 open-vm-dkms

Does that resolve the ". . . . maybe a dependency" question?

When something is installed as a dependency, then it would show up in
the history. Assumed the OP isn't mistaken and the OP didn't install
something that included those stuff, then somebody has got access to the
machine. Somebody mentioned this already and I agree with this. I only

You said you wrote to the "top level directory".  I'm guessing you were
running as root and wrote to a section that you shouldn't have tampered with.
For example, a drive might appears both as /dev/sdd and /dev/sdd1.  You don't
want to mess with /dev/sdd - loosely speaking, that's just for the partition
table (i.e. use fdisk or one of its kin to alter if necessary).  
Read/write/mount
only the /dev/sdd1.

Of course the drive could have failed, but it seems unlikely.

Have you tried to fsck the drive?

Or simply apt-get purge open-vm-tools. Perhaps you can search in history
files in /var/log/apt/ directory and find entry of the open-vm-tools
package.

If they do, they should be aware that would essentially permit any user
on the machine to bind to any port; since nc is a redirection system it
can be paired with any daemon or program.

Well, that's good. Meaning, that's simply a misuse of root, not a
rooted host. No reinstall in necessary, probably, simple removal of:

/etc/init.d/vmtoolsd
/etc/pam.d/vmtoolsd
/usr/bin/vmtoolsd

should do it.

Don't forget to change the root password just in case.

Three possible ways:

1) Unofficial install media. You won't believe what kind of strange
gizmos people put into these ;)

2) Lack of physical security. Remove an HDD, place it into another
host, copy some files, put back.

3) Someone has a root password, and that's not you. Or, you left root
shell and an unlocked screen, someone has used it.


> By the way, do not have sshd installed (and there is no /usr/sbin/sshd).

I mentioned sshd as an example. There are plenty of ways to do remote
connection to the host (telnet, VNC, XDMCP), all of them can be used
for the root access.

Just to be on a safe side, scan your host with 'nmap -sT -sU 1-65535'
for both ipv4 and ipv6. Consider blocking everything unneeded with
iptables.

Check to see if you have any new users or groups added to your system
that look suspicious. The log entry for vmuser indicates that someone is
or has tried to use your system as a vmuser. I use this type of login on
an OpenVZ system that I use on a remote host. That may give you some
insite.

Great, thanks! I didn't know about debsums.
However, it does not report anything when started from the debian live usb.


4) If, and only if debsums won't report anything unusual - purge
vmtoolsd, cleanup anything in /usr/local, change root password,
remove any ssh public keys from /root/.ssh/authorized_keys, reboot to

5) If debsums show any file replacements

I will format disk and do the fresh install anyway, but I simply do not

By the way, do not have sshd installed (and there is no /usr/sbin/sshd).

Because that's the low-end package manager job, and, - surpise! - dpkg can
do that.

dpkg -S /path/to/dile 

for installed packages.

There's also apt-file, too, if you look for what (un)installed paclage
a file is in. That one looks in the ahives Contents files

Accessing Glipper in testing (Jessie)

[David Parker]

Hello,

I was running Wheezy for a while, with a little bit of tweaking, I came to
enjoy the new Gnome interface (I had been a KDE fan for years until I
upgraded to Wheezy).  In installed the Glipper clipboard manager and could
access it by placing the mouse cursor into the lower right corner of the
screen.  It was otherwise hidden, and I thought the whole thing was very
slick.

I recently upgraded to testing, and Glipper disappeared.  It's still
installed, but I can no longer access it like I used to.  The only way I
can find to access Glipper is to open the Gnome Tweak Tool and enable the
"Window list" extension.  This enables a traditional task bar at the bottom
of the screen which shows the currently open windows, a workspace switcher,
and at the very end on the right it has a blue circle with a "1" on it.  If
I click on that blue circle, a gray bar slides up and shows the Glipper
icon, which I can then click on.

I don't care for this solution, because the task bar takes up space at the
bottom of the screen and I can't seem to hide it, and I also have to click
the blue circle in order to get to Glipper.  I neither need nor want the
window list or workspace switcher, so to have it there simply for the
puspose of accessing Glipper is irksome.  It was much nicer when I could
simply move the cursor to the lower right corner without clicking on
anything.  Is there something I can do to get this old behavior back?

Thanks in advance.

- Dave

P.S.  Yes, I do realize that I can use CTRL-ALT-C to pop up Glipper
anytime, and that's what I'm doing right now, but I really liked the
mouse-only solution I had before.

Thank you. Using that command it'd be trivial to see if those files were 
installed by the package manager, maybe a dependency, which is more likely 
than being compromised, in all honesty.

Rather than getting paranoid, go see if APT has a tool that does the same

To answer your question - yes, you're right being paranoid.

In Debian, software doesn't install by itself, installing a
software requires human intervention. You didn't do it = someone else
did it.

Whenever virtualization can be used to gain a backdoor is irrelevant
here, what's relevant is that someone has a root privileges on your
host already.

Now, whenever these privileges were carelessly used to install vmtoolsd
Slackware-style (i.e. not using apt or deb), or these privileges were
used to do something more (say, replacing sshd with its' keylogged
version) - that's really interesting.

I suggest you to:

1) Reboot the system using the good-known LiveCD. That's really
important as you cannot trust the integrity of the OS on this host.

2) Mount host's / filesystem and /var filesystem somewhere ('/mnt' will
do).

3) Run

debsums -ac -r /mnt

4) If, and only if debsums won't report anything unusual - purge
vmtoolsd, cleanup anything in /usr/local, change root password,
remove any ssh public keys from /root/.ssh/authorized_keys, reboot to
normal.

5) If debsums show any file replacements
(especially /usr/sbin/sshd, /bin/bash, etc) - reinstall the OS from the
scratch.

Sure, there's a way. Remove NetworkManager and wicd as both of them are
unsuitable for managing network settings anyway. Install wpasupplicant
and resolvconf (unless you have them already).

Configure your network interfaces at /etc/network/interfaces:

1) Wired - the usual way, with 'gateway' and 'dns-nameservers' stanzas.

2) Wireless - in accordance
with /usr/share/doc/wpasupplicant/README.Debian.gz, section 'Roaming

ethernet and wifi together

[S3v3ran .]

Hello

My scenario is the following. I'm connected to the wired network, which is
the default network i'm using. The default gateway, DNS server and
everything else is via this interface. On the other side i have some
virtual machines inside and i need them to use the bridged wifi connection
(because the wired one is behind a proxy server). For this i also need to
have connected the wireless network (using WPA2-PSK). When i use Wicd. When
i use Wicd to connect to wifi, it automatically disconnects me from
ethernet and when i connect to ethernet, it disconnects me from wifi. Both
connections (wifi and wired) should be configured dynamically (i'm using
various networks at home or in the company). I tried a network-manager but
I couldn't connect to wifi with it. Is there a way how to connect
dynamically to both interfaces, using the eth0 as default route? Thanks in
advance.

Multiple dns servers are for REDUNDANCY. So if one fails and is no longer 
available you will automatically use the next one available.

Ok, so
1: Make sure to either disable DHCP in the router or make sure the router 
cannot answer those devices
2: Enable DHCP (isc-dhcp-server) on your linux machine
3: in the /etc/dhcp/dhcp.conf file have a line that points to the proper dns 
server

Me, I have a linux box conneted to the LAN and the and the router on the same 
NIC. Internally I use 172.16.17.0/24 and my router is on 192.168.178.1
In my /etc/dhcp/dhcpd.conf file I have:
#network definition
shared-network internal.xxx.xx. {
  subnet 172.16.17.0 netmask 255.255.255.0 {
option routers 172.16.17.1;
option domain-name-servers 172.16.17.1, 194.109.104.104;
option ntp-servers 172.16.17.1;
range 172.16.17.20 172.16.17.39;
range dynamic-bootp 172.16.17.40 172.16.17.45;
default-lease-time 86400;   # one day
max-lease-time 172800;  # two days
  }
  subnet 192.168.178.0 netmask 255.255.255.0 {
  }
}

This provides all information to the clients. If you want the router to handle 
all the traffic directly and not via the linux machine then change the "option 
routers ..." line. But...
If you want it all in one network range then change that part of the setup too.
For me, my linux box routes between several segments which my ISP router knows 
nothing about, which is why it is the default route for my network. Also, it is 
why I run my own dns server. Because there I CAN tell it where to look for the 
proper information if it is not available on the default "internet" dns servers.

Off-list someone suggested I restart the cron daemon, which I have done.
I won't know if that helped until tomorrow morning, though.

Re: Am I paranoid?

[ha]

Hi

I cannot see a package named "vmtoolsd" in the debian archives. But I
can see a package named "open-vm-tools", which has files named like
that:



Yes, I know. No, I do not have "open-vm-tools" package.



This package seems to be the VMware Tools bit intended to be installed
on a guest VM - i.e. it does not provide virtualisation, but does
stuff guests...

Is your box a VMWare guest? If not, then you should not need open-vm-tools.



Yes, I know. No, my computer is not a virtual machine and I did not 
install on it any virtual machine software (and especially not VMware).


My guess was that somebody assumed it is a VM box. (That's why I 
mentioned stealing of processor cycles)




I would not suspect this to be the case here. If you have the
open-vm-tools package from the Debian repository, you should be safe.

Hope this helps



No, according to synaptic I do not have installed any package that has 
"VM" in it.


But thanks anyway.

Re: resolv.conf misbehaving

[Danny]

Hi,

My apologies, I must have missed your reply

> 
> If you query the first server for an information out of its scope, it

However, what would be the point of giving resolv.conf multiple nameserver
options then (if I understand you correctly), if one cannot "force" (for lack of
a better word) it, or even arbitrarily change the order in which servers can be
queried? So it would be absolutely pointless in even trying?

I think I am missing something somewhere, previously (Debian 3.0 and even later)
one could add multiple nameservers in resolv.conf and the list would be queried
one at a time if an ANSWER SECTION could not be obtained from the previous one.
I fail to understand then the reasoning for "limiting" resolv.conf (and
everything associated with it).

I am no expert (by a long way) when it comes to any sort of DNS, but you don't
need to be a Doctor to know when someone is ill.

The setup I had (Debian 3.0) worked. Unfortunately smart devices and more
wireless laptops demanded attention. So I upgraded (clean install) to Debian
7.0. All I want to do is for all wireless devices to get DHCP from Debian (not
the router) and query Debian (not the router) for name resolution. Simple as
that.

I appreciate your input.

Thank You

Danny

Authentication problem which ejabberd using ODBC

[Daniel Bareiro]

Hi all.

Some time ago, I decided to migrate from a compiled ejabberd 2.0 to
version 2.1.5 from Debian GNU/Linux repositories.

After that, everything was working, although the weekend I was checking
some things of setup and I noticed that was running with a version of
MySQL modules I compiled at the time (2011).

The idea is that everything is running Debian packages for ease of
administration and security updates. Then I tried the authentication is
done with ODBC.

Then, to achieve this, I commented the lines:

---
{host_config, "sysadminhaiku.com.ar", [
 {odbc_server, {mysql, "localhost", "sysadminhaiku", "ejabberd",
"password"}}
]}.
---

and added these lines:

---
{odbc_server,
"DSN=MySQLEjabberdSysadminHaiku;UID=ejabberd;PWD=password"}.
---

But I get an authentication error:

---
I(<0.568.0>:ejabberd_c2s:649) : 
({socket_state,tls,{tlssock,#Port<0.4138>,#Port<0.4140>},<0.567.0>}) Failed 
authentication for dan...@sysadminhaiku.com.ar

---

Could the authentication error be related to a connection issue? What I
find strange is that I did a test with isql, and the connection is
established. When I undo the change and authentication is back with
Erlang compiled modules, everything returns to normal.

Any idea what could be the problem?


Thanks in advance for your reply.

Regards,
Daniel

cron.daily logrotate beating up my server

[Tazman Deville]

I have a little server running here in my office,
and logrotate kept running at c. 7am, and using up 100% CPU.
I changed the line in /etc/crontab to run cron.daily scripts
at 4:15am, instead of 7:whateveritwas am.
15 4 * * *
Also, in cron.daily/logrotate
I added 
nice -n 15
I made these changes two days ago,
and still, yesterday and today, logrotate is running at 7:30ami-ish,
and using up almost 100% of CPU cycles.
The "server" is an old refurbed eMachines box,
3.2ghz single core celeron with 2gb ram (was my work box from 2007 to
2011), and logrotate is beating it up.

How do I get logrotate, first,
to run at a time when the server is not busy with other stuff 
(I'm actively doing stuff on the server at 7am, but not at 4am, which is
why I had made that change).
and/or
limit its abuse of CPU cycles?

Why is it seemingly not honouring the changes I made to /etc/crontab
and cron.daily/logrotate?

I had that same issue at the weekend. Somehow my amd64/x86 multiarch
machine had got libc6:i386 at 2.18 but libc6:amd64 was at 2.17. I think
it was this mismatch that was throwing segfaults.

In the end, I was able to complete the upgrade by:
 * Download the libc6:amd64 deb
 * dpkg-deb --extract  
 * dpkg-deb -e  
 * Edit /DEBIAN/preinst and insert "exit 0" near the top
 * dpkg-deb -b 
 * dpkg -i 

This skipped some checks, but it did get things back in sync and I was
able to complete the upgrade.

Note, however, that due to a conflict with an existing package (node aka
ax25-node), Debian ships the binary as /usr/bin/nodejs. If you need to
use the old name (/usr/bin/node), then the node-legacy package seems to
provide for you.

There is also ncat, which comes in the nmap package and is described as
"a much-improved reimplementation of the venerable Netcat". This is what
the OP is apparently using. He might also have nc aliased to ncat.

I'd not previously come across the CAP_NET_BIND_SERVICE capability Pascal
Hambourg mentions; the OP could consider doing (as root)

   setcap cap_net_bind_service=+ep /usr/bin/ncat

as a solution to his problem.

And the excellent crypcat - but I just counted the ones with netcat in
