Networking :: SNMP Error - Encryption Support Not Enabled
Nov 1, 2010
When I run the following GET commad:
./snmpget -m ALL -M /data/net/naamab/snmp/snmp_mib/ -v 3 -a MD5 -l authPriv -u test1 -A welcome1 -x DES -X privpass 127.0.0.1 NOVELSAT-MODULATOR-MIB::nsModLineCMMode.0 -d
I get the error:
Encryption support not enabled.
snmpget: USM encryption error
I have defined a user (and user, view and access) that should work with encryption:
snmpd.conf:
createUser test1 MD5 welcome1 DES privpass
group debugGroup usm test1
view debugView included .1
access debugGroup "" usm priv exact debugView debugView none
General details:
I am using net-snmp on linux embedded
version 5.5
Configuration (part of it):
./configure --target=mips64-octeon-linux-gnu
--build=mips64-octeon-linux-gnu

I have an issue when sending snmp traps. I have an embedded system connected to a SNMP manager. I am sending traps from the box to the manager continuosly. After sometime I don't see any trpas coming out.
I get this error message.
Cannot open file /proc/net/tcp ...
: Too many open files
Cannot open file /proc/net/snmp ...
: Too many open files
What could be the reason for such an error?

In both CentOS 5.5 and FreeBSD 7.4 when I use
Code:
snmpget -v 1 -c public windows_host system.sysDescr.0
I get the remote windows machine system description just fine. But not in ubuntu.
Searching snmp-net FAQ for the erroe message "Unknown Object Identifier", I got this to work around
Code:
snmpget -v 1 -c public 127.0.0.1 SNMPv2-MIB::system.sysDescr.0
But it not worked either.. Searching "MIB" using apt-file search, I installed "snmp-mibs-downloader", and now
Code:
snmpget -v 1 -c public 127.0.0.1 SNMPv2-MIB::system.sysDescr.0
works.. but
Code:
snmpget -v 1 -c public windows_host system.sysDescr.0
still breaks..
Why it works in CentOS and FreeBSD but not in Ubuntu?

I just tried to create a qemu qcow2 image with encryption:
Code:
qemu-img create -e -f qcow2 foo.qcow2 100G
Formatting 'foo.qcow2', fmt=qcow2 size=107374182400 encryption=on cluster_size=0
It's some time ago I played with qemu, but I think it's supposed to ask for a password.
If I start the image with
Code:
qemu foo.qcow2
it just says 'QEMU [Stopped]' in the popup terminal window. It starts normally without the encryption option on qemu-img.
Is encryption known to be broken? Is this perhaps specific to qemu with KVM patch or to the 64-bit version?
Ubuntu 9.10
qemu-kvm 0.11.0-0ubuntu6.3
Linux wallace 2.6.31-19-generic #56-Ubuntu SMP Thu Jan 28 02:39:34 UTC 2010 x86_64 GNU/Linux

Running ubuntu 10.10 here, brand new install/machine.USB wireless based on a realtek chipset. I spent a few days trying ndiswrapper, and now have the native driver up and running. I can see the network(s) but can't connect. If I encrypt the network, i get a bad password error from wicd network manager (All encypt. methods- Weps, WPA etc) If I open my wireless up with no encryption, i receive a "can't obtain IP" error.

I would love to be able to use TrueCrypt consistently across all my machines, be they Windows or Linux. As it stands, I can do full-disk encryption with pre-boot authentication only on Windows.
I don't really understand why this is. Are there technical challenges specific to Linux/Mac that make full disk encryption harder? Does anyone know whether TrueCrypt will support this in the near future.
PS. yes, I'm aware that there are other options. My goal is to simplify my life here and use the one tool across all machines.

currently running karmic on an old gateway laptop with kernel 2.6.31-22-generic and, as is par for how I handle challenges, I've jumped in with both feet - which is to say this is not a dual-boot situation. I've spent some time reading the forums (and other sources of information) and am grateful for all the knowledgeable people who are willing to share what they know.
My operating system seems to be functioning properly.I can get online via ethernet, but not via wireless. I have a lucent orinoco gold PC24E-H-FC (PCMCIA) card, which the computer isn't seeing. I am trying to follow the instructions here: [URL] to install the driver. Everything is going well until I get to the sudo make line. At that point I get the following display:
make -C /usr/src/linux-headers-2.6.31-22-generic M=/usr/src/orinoco-0.15rc4 KERNELRELEASE= modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.31-22-generic'
/usr/src/orinoco-0.15rc4/Kbuild:8: *** Wireless extensions are not enabled. Stop.
[code]....
how I can fix it so I can continue on with the instructions. (For the record - if I just continue on, I can change directory in the next line, but I cannot remove either hermes or orinoco as "no such file or directory" seems to exist.)

where I can find a package for mplayer with dvdnav support enabled?
I was disappointed to discover that in 10.04 dvdnav support was disabled in mplayer. I rely on it for my mythtv front end box to be able to play DVDs. According to a bug it was disabled because of an upstream email chain where dvdnav was considered 'experimental' and 'not ready for production use'. Funny as it worked fine for me.
Post #6 here is where I found the above reasoning for it being disabled.

I keep getting the following error when I run the following:
Quote:
# iwconfig wlan0 key s4ssw0rd Error for wireless request "Set Encode" (8B2A): SET failed on device wlan0 ; Invalid Argument
No matter what method I try for setting an encryption key for my card, it doesn't work. I am only able to connect to wireless access points that don't use encryption.
details: I have an Atheros AR9285 wireless card, I have the mac80211,ath9k modules loaded. Also when I run lspci, my Atheros AR9285 card shows up on the list. I am using the 2.6.30.9 kernel.

I am building an active directory and using BIND9 as my DNS. To allow for secure dynamic updates from the domain, I am enabling GSS-TSIG as detailed here and here. Unfortunately, some of the commands and configurations used here seem to be depreciated, at least in the newer versions that I'm using. My issue is one of keytab encryption. I generated a keytab using ktpass.exe on the Windows Server 2008 domain controller. I have tried DES/MD5, AES128/SHA1 and AES256/SHA1, each have been turned down by ktutil on the kerberos server (FreeBSD). Each time, it outputs the following error: ktutil: AES256/SHA1*: encryption type AES256/SHA1* not supported *Respective to encryption used.
I cannot find a list of suitable encryption schemes that ktutil will accept. The FreeBSD handbook details a means of producing a keytab file, but I'm not sure how to configure the Domain Controller to use the keytab.

I am trying a release of Ubuntu has have run into a problem that does not make much sense. I am receiving the following error: Syntax error on line 20 of /etc/apache2/sites-enabled/portal: Invalid command 'ProxyHTMLEnable', perhaps misspelled or defined by a module not included in the server configuration
fail! I believe the modules required for this is apt-get install libapache2-mod-proxy-html and it shows under the available modules and it was enabled with a2enmod proxy-html.
The line from the config is ProxyHTMLEnable On. The release is the latest download with updates from, 32bit.

I have enabled SNMP monitoring in my debian box (using apt-get install snmp) and configured it to allow my PC to query the server.
I'm able to query the server and get SNMP data but when I get STG to give me a per/second graph of the interface octets, it only updates the data every 12 seconds or so.
Is this a setting in SNMP which could be causing this problem? If so, how can I enable it so that SNMP can give me up to the second octet rates.

2 machines (one of them working as a server to monitor the network with IP 192.168.100.110 and the other one to be monitored with IP address 192.168.100.1):
In the first machine:
snmpwalk -v1 localhost -c public sysName (working fine)
snmpwalk -v1 192.168.100.1 -c public sysName (don't works -> Timeout: No Response from 192.168.100.1)
In the monitored machine:
snmpwalk -v1 192.168.100.110 -c public sysName (it works)
snmpwalk -v1 localhost -c public sysName (dont works -> Timeout: No Response from localhost)

I have recently set up nagios on a ubuntu server (9.10), and set it up to monitor all the servers, switches etc, following the quickstart guide provided on the nagios website.My problem is this:I have setup the nagios-plugins, and tried to set it up to monitor the network switches via SNMP but receive the following within the nagios web interface:SNMP problem - No data received from host I tried it from the command line, and got the exact same error.Is there some further configuration I need to do to be able to get this data?I've used up all my google-fu, and read over everyone else's problems on every forum I could find, but to no avail.

I have created this thread as it sis realy hard for me to send traps from my Linux workstation... I m lost with v1/v2/v3 snmp... So here is the initial configuration: (without traps)
rocommunity myrocom
rwcommunity MyL33tP4ss 10.5.32.202
rwcommunity MyL33tP4ss 127.0.0.1
syslocation "FR"
syscontact root
From there i can "poll" my system. But what should i do if i want my Linux system sending traps when disks are full or system overloaded etc...I have found information on Internet but not easily understandable It is for v3:
rwuser admin
createUser admin MD5 mypasword
#
# From there i would have to comment the lines regarding the communities
#
[code]....
10.5.32.202 is my management host ... is this config ok ? But it seems that trap2sink is for v2 ? How does it work ?

I am trying to monitor a Centos 5.3 box using SNMP and I am having a lot of trouble getting the data that i need from it. Everytime I try to get information from the UCD-SNMP MIB it returns "End of MIB". It is my understanding that UCD-SNMP is a standard package when Net-SNMP is installed and should always be there. Then why can't I access it? I have tried removing the reinstalling Net-SNMP, but that hasn't worked. My server is update date on all it's patches as well. It is quite old hardware, but I don't believe that should affect SNMP from being gathered. Iptables is down, and I cant' even get it from the local machine.
