Help in local-user and iMC.......

MohammadH — Sun, 24 Mar 2013 09:48:03 GMT

we have local user (admin) in the switch 4800G and 2900al I want to see what the configure he change from iMC we have 70 switch I want to see them all in the same time not go to switch's one by one to see the log.

and thank you.

If I'm understanding it right, what you want to do is to generate a report that shows you all changes, across all devices (or maybe a group of devices). Is that correct?

I don't think that this capability currently exists. It's easy enough to see what's changed on an individual device basis, but it's not so easy to generate a single report showing changes across all devices.

I haven't dug into the ProCurve options around logging commands, but you may be able to get the switches to log all executed commands to your syslog server. I know you can do it with IOS, so it should be possible on HP switches. Set the syslog server to be the IMC system, and you'll be able to see the logs.

You should also be using centralised AAA, so you can control users, and log all commands. Then set up an alert whenever someone logs in with a local admin account, rather than using AAA.

I think you don't understand me I mean by local user in the switch not a computer user I want to know what the change in group of (switch's) in configure like vlan , inter disable,... ,

and

how can I Set the syslog server to be the IMC system ?

I try to use Configuration Templates I add new Template the configure for the Template you can see it in the attachment.

Thank you for your help.

I wasn't referring to a computer user - I was referring to users logging into the switches or routers.

Thank you for your help.

Config to set the syslog destination on a Comware-based switch would look something like:

info-center enable
info-center loghost 10.1.1.200
info-center source default channel loghost log level information
info-center source default channel loghost trap level information
info-center source default channel loghost debug state off

In general, if you want to look at logs across a range of devices, you don't log into them all and go "display log" - instead, you configure them to all send syslogs to a central destination, and you search there. Using config templates in IMC is more intended for pushing out configuration changes, rather than looking at logs.

sorry I misunderstand you

thank you for the configure can I have the configure for 2900 and do I need change any sitting in iMC so he can get the log from the switch ? I want to ask can make the iMC send email if the user change the configure in the switch's ??

and

Thank you for your help

Re: Help in local-user and iMC.......

LindsayHill — Mon, 25 Mar 2013 07:53:41 GMT

On ProCurve, the commands are something like:

logging 10.1.1.100

logging severity info

IMC will be set up to receive syslogs by default, BUT you may need to check your firewall on your server, to ensure it allows inbound syslog.

Once IMC is receiving syslogs, you should see syslogs at Alarm -> Syslog Management -> Browse Syslog.

If the switches are configured to send SNMP traps to the IMC server, and they send SNMP traps for config changes, that will generate alarms, which you can use to send emails. Those will just be generic alerts every time someone enters config mode.

If you want more complex alerts, you can configure syslog templates to match specific patterns, configure syslog to alarm escalation, and configure email alerts based on those.

MohammadH — Tue, 26 Mar 2013 05:43:44 GMT

thank you for configure for the ProCurve, are you by (If the switches are configured to send SNMP traps to the IMC server)

you mean the config for the syslogs ?

and thank you for your help.

Re: Help in local-user and iMC.......

LindsayHill — Tue, 26 Mar 2013 06:14:50 GMT

No, SNMP traps are configured separately to syslogs. They are different protocols, used for different purposes (although I guess there is some overlap in use/functionality).

You might want to do some reading on SNMP, and traps, and how they work in general. Might make it a bit clearer.

Re: Help in local-user and iMC.......

MohammadH — Tue, 26 Mar 2013 06:52:45 GMT

I know what the SNMP traps I want to know how to config the switch and iMC so if someone login to switch or change the config or the login fail or successful the iMC will send Email Notification.

I try to do it but No luck...!!

Thank you for your help.

OK. Let's start from the top. If you want an email on all logins, and config changes, then let's start by using syslog.

On the switches themselves, when you login and make a change, does it display anything in your syslogs?

Deal with that first. You may need to change the configs. I haven't looked into it for Comware/ProCurve, but Cisco switches need configuration to log failed login atempts.

Once that's working, make sure that the switches are sending syslogs to the IMC server.

When you've got syslog entries for logins + config changes being sent to the IMC server, and visible in Alarms -> Syslog Management, come back here, and we'll walk through turning those syslog entries into emails.

The other thing you should be doing is implementing centralised AAA. This will give you MUCH better visibility and control.

Re: Help in local-user and iMC.......

MohammadH — Tue, 26 Mar 2013 10:51:28 GMT

if you mean by implementing centralised AAA the RADIUS server if that so we plan it in the future to install RADIUS server,

I finish configure in the switch when I change the config in the switch I can see it in the :

(Alarm -> Syslog Management -> Browse Syslog),

so what the next step ?

LindsayHill — Wed, 27 Mar 2013 08:29:24 GMT

You can use either RADIUS or TACACS (with IMC's TAM if you like) for centralised access control.
 
Now, if we used SNMP traps, we can immediately escalate those to alarms. Since it's syslog, we need to go through another step. Bear with me, and we'll work through it in stages.
 
First you need to define a Syslog Template. This will match specific patterns in the syslog entries. We can later use this template to create alarms. Once we can create alarms, we should be able to turn those into emails. 
 
Go to Alarms -> Syslog Management -> Syslog Templates. Click Add, and give it a name, and Template Content. This is the patterns to match in the syslog entry. Note that you can grab specific parts of the syslog, and assign them to parameters. For now, maybe just keep it simple. If your syslog entry looks something like this: "User admin logged in via console", then you could have a pattern Template Content like: "User $(user) logged in via $(interface)"
 
Click OK to save that.
 
Now go to "Syslog to Alarm". Click Add. Give it a name & Description. Key things to change here are the Alarm Level, and the Repeat interval/repeat time. The default is to only generate an alarm for 50 events in 300s. You probably want 1 event in 1s. Set the severity to whatever you want. 
 
In the "Alarm Description" field, just leave it as %syslog% for now. Later you can change the message if you like, using some of those parameters we got earlier. Select a Syslog Template - use the one you defined earlier. Hit OK on that.
 
Now try triggering some of the events that cause that syslog. See if you can see the entry in "Browse Syslog". Then go and check "Alarm Browse -> Real-Time Alarms", and see if you can see the alarm there.
 
Get that working, then we'll look at generating emails.

I want to ask the do I need active directory with TACACS ? If so is there a way to use TACACS without active directory ???

and

will the (User $(user) logged in via $(interface)) work with telnet ?? or only the console ?! Because I try it whit telnet but can't see anything in (Alarm Browse -> Real-Time Alarms) ?!

I have Filtering Trap will it effect the syslog ? I have attachment you can see the Trap.

LindsayHill — Wed, 27 Mar 2013 08:29:02 GMT

I haven't used TAM, so I can't comment on that. You'd have to read the docs.

That template example was just a random example - I don't know what your syslogs patterns look like. You need to look at your syslogs, and come up with a pattern that works.

LindsayHill — Wed, 27 Mar 2013 09:15:08 GMT

So what settings do you have for your syslog template, and your syslog to alarm policies?

Looking at those logs, you could probably also use snmp traps if you wanted.

LindsayHill — Wed, 27 Mar 2013 23:00:25 GMT

My advice would be to start simple with your templates. Don't worry about parameters, etc. just yet. Keep it simple, until you know you're matching what you need.

e.g. for the Failed Login syslog, I might just look for "h3cLoginAuthenFailure"

Make sure that your syslog to alarm template changes the counters too, to alarm for every message, not for the default of 50 messages received in 5 minutes.

Hi,

On comware devices (4800), you can enable shell logging to a specific syslog server. This means that all typed commands (as shown in the local log file with display logging) can be sent to an external syslog server.

If you do not want these on the default syslog server, you can use a dedicated channel (output channel), disable all other features (default), and enable the SHELL source on this new channel.

Next configure a specific syslog IP for this channel.

This would be a sample config:

info-center channel 6 name loghostshell
info-center source default channel 6 log state off trap state off
info-center source SHELL channel 6
info-center loghost 192.168.5.42 channel 6

This is not possible on provision devices. For these you need to configure an external radius server for login. The provision switches can use radius accounting to log all operator commands to an external system.

I have attached a configuration guide I have made in the past which explains the steps with a microsoft NPS radius server.

Hope this helps,

Best regards,Peter.

Hi northlandboy

sorry I take long time, I make it work but only send email the first time I login but sometime not send email and same for the command when I input any command it only send the first command then will not send any email so it almost work,

I use more then one templates for login and and logout, for the command change:

for the login:

---------------

<h3cLogIn>: $(UserName) login from VTY

------
$(UserName) logged in from $(Source IP).

------------------------------------------

for the logout:

---------------

<h3cLogOut>: $(UserName) logout from VTY

------
<h3cLogInAuthenFailure>: $(UserName) failed to login from VTY, reason is 2

------
TELNET user $(UserName) failed to log in from $(Source IP) on VTY0

------
$(UserName) logged out from $(Source IP).

-----------------------------------------------------

for the cammad change:

-------------------------

-Task=vt0-IPAddr=$(Source IP)-User=$(UserName); Command is

$(Source IP)-User=$(UserName); Command is

------------------------------------------------------------------------------------

hi Peter_Debruyne

thank you for the guide it really help me , and for the config sample.

thank you for taking your time to help.
