SNMP: GET/SET vs. TRAP
Hi, net-snmp's GET/SET mechanism looks completely separated from the TRAP mechanism, which I find quite bizarre. NET-SNMP claims to be easily extensible with Perl (http://net-snmp.sourceforge.net/wiki/index.php/Tut:Extending_snmpd_using_perl) However, this extension doesn't know what a TRAP is, only handles GET/SET commands. It seems as if I have two options: A. Write a completely separate Perl daemon that sends traps using Net::SNMP (completely separate code for sending TRAPs and handling GETs/SETs??) B. Write a subagent in C (a separate process that talks to snmpd), which handles both GETs/SETs TRAPs. (Is that the common approach?) Am I missing something?

RE: SNMP: GET/SET vs. TRAP
Hi, Conceptually, there's a big difference between get/set and traps: get/set messages in SNMP are always requested by the management application and responded to by the SNMP agent. Traps, OTOH, are messages that are sent, unsolicited, from the agent to notify the management app of something of interest that has happened without having to wait for polling.

Re: yet another Hot packet drop
Few rules from an expert. 1. Try to ping some web site. google, ynet (to compare). 2. with mtr you can detect the ip from where you get packet loss. 3. traceroute google.com (if you see *** at some part of the trace, you hit a firewall). 4. tcptraceroute google.com (bypass firewall. Sometimes you get there , 2nd proof of firewall). 5. hping2 to bypass firewall. 5. use firewalk . Firewalk is an active reconnaissance network security tool that attempts to determine what layer 4 protocols a given IP forwarding device will pass. I recommend to read the man of firewalk. 6. If you have the ip (from mtr) go to http://www.dnsstuff.com and put the ip there. You will find if this belongs to hot or bezeq.

The only way you could ping Hot infrastructure directly is if you can do it via the ethernet connection directly rather than via the tunnel.

official way to load wifi in Red Hat/Fedora?
Hi, After 2 weeks of struggling with my wifi (Cisco Aironet 350) I finally gave up and bought a cheap Belkin PCMCIA WIFI card and finally I managed to make it work with my WiFi and WPA-PSK. What I'm looking for is some official way to load and configure it. I could write a script which detect if the card is inserted, if so, load the kernel module (if required), run wpa_supplicant, and finally dhclient, but I think that there is some more official way to do that, but I cannot find it. Any suggestions?

Memory leak question
Hi List
One of my servers is acting very strangely memory wise - it has 4GB of
memory and it is always full, and I don't mean in the not a lot of free
memory kind of full, but in the application memory takes more then
3GB kind of full.
I ran a simple script to compare how many resident memory PS reports
compared to what free reports is being used for stuff other then cache
and buffers, and I got these interesting results:
This is a normal which is very loaded and by right - it has a java
application which is set to 2GB heap and uses it just fine:
# ps auwx | perl -nle 'split/\s+/; $sum += $_[5]; END { print sum:
$sum; }'; free
sum: 3158192
total used free sharedbuffers
cached
Mem: 40634124029396 34016 0 20016
360368
-/+ buffers/cache:3649012 414400
Swap: 4194296 3541883840108
So we can see PS reports 3.1GB is used by applications and free reports
3.6GB of used memory (except buffers and cache). so I'm missing about
half a gig, but I don't mind that much.
Here is the broken server:
# ps auwx | perl -nle 'split/\s+/; $sum += $_[5]; END { print sum:
$sum; }'; free
sum: 1367356
total used free sharedbuffers
cached
Mem: 40634124038212 25200 0 35604
726268
-/+ buffers/cache:3276340 787072
Swap: 4194296 6565083537788
which is mind boggling - there's a 2GB difference, about half my total
amount of memory! Where did all my memory gone too ?
Now that server is also constantly spends tons of time in kswapd and on
IO - thrashing if you want and I'm not sure if its a symptom or the
cause.
Do note that both are production servers and I can't really restart them
or anything, even taking down services is a long and annoying process.
Please throw your two cents my way, thanks.

I just noticed something else - both servers are running MySQL, and I'm
using htop (instead of top) to look at processes. Now in the good
server htop lists MySQL memory share as 8.5% and the numbers are
VIRT=615M and RES=329M , while in the bad server htop list MySQL as
using VIRT=1364M and RES=409M but lists it as only 3.8% of memory ?!?
both servers carry the same 4GB of physical memory and 4GB swap.

Re: official way to load wifi in Red Hat/Fedora?
That documentation is highly out dated. NetworkManager is doing WPA for a long time now (I've been using it more then a year and it had supported WPA all along). I just managed to make it run. I must say, even if in version 0.7.0 (I'm using Fedora 8), it's not the most stable application I've seen. BTW, how do you make it work without using X? (init level 3, X not running). NetworkManager is actually a service that your distro should run in its SysV boot sequence (or whatever they use to boot), and then it has a user application (nm-applet for gnome, knetworkmanager for KDE) that is running in each user's session that offers an interface for the user to select networks and input configuration and security details - and the application talks with the service over dbus so you'd need the message-bus service to also work. Any recent Fedora (7 and above I think) should have that configuration by default. Yeah, the fun part is that with Cisco aironet Wifi which is built on my thinkpad, it specifically says that WPA is supported, but not according to NetworkManager.. Thanks for the help.

[li..........il: related]: Quantum relativity 0.1 completed counting backwords in time; all numbers base 21 [r].
My dear friends from the li.*.il network*; OK sorry for being still paranoid, but I will not let Americans do to me what they did to my friend John Nash in the past. They have their reasons not to allow this, and I had enough. I want to be able to receive communication from friends and not non-friends, and nobody should read my mail or restrict me to this planet. Actually I didn't know there are living anys outside this planet, but this is because the USA Americans not wanting us to find out. So I'll tell you what I'm going to do: 1. since math is universal and even the US Armee can't lie about 1+1, I'll define my own math in such a way that even if there is an axact copy of me now outside what we call the known universe, he/she will be able to communicate with me, plus if there is any un-none inside black wholes etc., I will not need light or even black quantum light to receive information from there, I will just define them to be mathematically closer to me than the faraway science spacetime expanding say and they will just become quantum timespace shrinked inside the empty space of my hands typing you this (relativity will make it work actually, you will see). 2. And since we are too used to the digits 0;1;2 etc. and what they mean to us, they are not symmetric and I need to define them in a symmetric way (remember one=none=one+one=none+none etc?). so let there be digits n and o ; stand for one and none or (k)none and un(k)none, whatever you want or you can have m for the moon, p/n for positive/negative, r/i for real/imaginary etc. so lets start with n/o, that will be enough for me to define everything (actually even one of them or even none of them (just empty space) is enough). 3. So let it be n=o and o=n; completely symmetric, and I'll define their new math: o/n: no equal signs, dots, minus, plus, nothing. o can be either one or many, haff or double or three apples and you can eat all at once with one mouth and decide who's the better. o==o; o [isequalandnotequal] to o n==n; n [isequalandnotequal] to n [of course it looks different, has a direction (spin), but o does too]. base o:onary/binary/baseany. Must be compatible with at least bases 0;1;2;3 now: to not confuse myself (and YES: confuse US Armee) I will use ono and non and same difference representing 010 and 101 respectively (but equally too); 010=101and therefore ono=non; ono plus ono = non [depends on the direction, multidimensional, plus/minus, real/imaginary etc. non plus non = ono [same sane] [==same same] OK now, since I told you 21 is my number, I am telling you that it can be any number, but of course for you allways 21 will be 3 times 7, which is true, but I will not tell you what scale are the 3 of 7, for example it can be plus or minus, positive or negative, real or imaginary, centimeters or meters. For example if 3 is in centimeters and 7 is in meters then 21 would be 2100 square centimeters [euclidan, remember to fold your papers] and depends on the direction, heat and can all be compressed to a tiny black hole; dimensions reversed etc. I just tell you that I will never let you count to 7 (or 3) without passing through my meter first, and they can be reversed to 1/3 and 1/7 or -1/3 and -1/7 as well (and then it's --1/21 etc.). And since 21 is a secret, it's the only (counting) prime number I'm allowing here, then I will pretend it to be equal to 12 to all who are not my real friends. And if spammers will send me information they will have to contact my friends first, or me, or repeat again and again the same message and I will just make it sound the same as nothing to me. So here's the plan: 2: no such number. Will be changed to either 1 or 0. all numbers other than 0;1:: same same. 21 will be 10base10 or 01base01 or 1.0.base1.0. or 0.1.base0.1 or actually also 0base0 and 1base1 and 0.0base0.0 and 1.1base 1.1; 12 will be 0.1base1.0 which is to opposite of 21. OK now. here's the plan. I will have digits trippled and doubled (can be changed later maybe): ono;non and non;ono who are equal (both same haff 0 or 1);one is ono and none is nono or vise versa - it doesn't matter so much. more strings:repeating:cutting by haff and replacing: one+one==: ono+ono==onoono==non; == 0.1 or and 0.4* 0.5* etc. (will change later) non+non==nonnon==ono; == same as above ono+non==ononon==onoono == 1.0 or 0.1 non+ono==nonono==nonnon == same now, if you have a number for me, I will ask you to convert it to me to base 12, which is either onononononon or nononononono - whatever side you are looking at it. so nononononono and onononononon are the even number 12 whois the first number counting and of course the first prime. But of course 12 is not a prime, but a permutation of 21 who I will tell you later how I represent it, right now you don't know but you have to be careful not to cheat me when counting, so you must be compatible with all bases 0,1,2,3,4,6 and 12 and of course 21. So at least you should be compatible

It's not like it has to sit there listening on some port - traps can be sent by any application at any time. fire and forget. B. Write a subagent in C (a separate process that talks to snmpd), which handles both GETs/SETs TRAPs. (Is that the common approach?) Not as far as I understand SNMP traps. Am I missing something? I think you do - just try to sit back and get your head around this - set/get are done with an SNMP agent (daemon) listening for queries and answering them. Traps can be sent by any application on the monitored host and nobody stays behind to see what happened to them.

Hi Thanks for your reply, see my comments below: On Tue, Apr 22, 2008 at 1:48 AM, sara fink [EMAIL PROTECTED] wrote: Few rules from an expert. 1. Try to ping some web site. google, ynet (to compare). Doesnt help, the ping lost is already happening at first hop. 2. with mtr you can detect the ip from where you get packet loss. yeah, that the ISP gateway, looking even further, the pptp addres (I know you were using DHCP so it was transparent to you) lost the packets (the 172.25.32.x subnet) 6. If you have the ip (from mtr) go to http://www.dnsstuff.com and put the ip there. You will find if this belongs to hot or bezeq. Some interesting things you will find there. its a 172.x which is not routable though the internet... 7. nmap to check how harsh the firewall is. Contact me in private to give you the flags. yeah, it comes back as a cisco router, probably doing some nat to the ISP pptp server. 8. One more friendly advice, don't tell them you have linux. You will get immediately the reply we don't support linux. Yeah, I got it already I've setup smokeping, and I think I have no way around it but to show them the bad performance. Thanks for your help, Ohad
