Routing

Hello

We have fw SRX1500 as the role as server log i will send you toplogie that you can help for configuration I want to configure router MX480 with configuration syslog but the BUT is to i want to use domain-name (fr-1vm-syslog03.infra.msv) as a remote server instead of @ip (not @ip) and also with dns 1

question1++ how to ensure the log is sent to the syslog server and be centralized ?

 Mean ==< What is the Juniper syslog template ( or configuration of cli ) that allows to send logs and be centralized on SRX1500 FW?

i wait a expert network in juniper help me

I'm not sure I follow the question.  It seems like you might be asking if the SRX1500 can be the syslog server and collect logs via DNS name from other devices.  The answer is no, the SRX or any Junos device can send logs to a syslog server but cannot be the syslog collector.

You can configure the external syslog server you sent to as a DNS name instead of ip address.

Yes remote syslog servers can be configured as domain name instead of ip address.  Naturally, the MX would need to also have a configured reachable name-server setting so it can resolve the name.

set system name-server 8.8.8.8 (Your internal DNS server here)

The syslog remote section:

set system syslog host fr-1vm-syslog03.infra.msv any notice

After the host name you need to pick a level of logging or more details to limit the types of logs generated.

Your diagram also notes that there are SRX firewalls between the MX and the syslog servers.  So you would need to have security policies in place from the entry zone of the routers to the destination zone of the syslog servers that permit the communication on syslog ports.

On your two SRX devices you would need to see if the security policy permit traffic from your devices to the syslog servers.  You can use the policy-match command to see if one currently exists.

Your zone names and ip addresses would need to adjust to the firewall where the to-zone seems to be SUPERVISION instead of Z2 and the from-zone varies by the device place on your network instead of Z1.  With the syslog being tcp 514.

This match needs to be checked for each zone pair on the SRX.

show security match-policies from-zone z1 to-zone z2 source-ip 10.10.10.1 destination-ip 192.0.2.1 source-port 1 destination-port 514 protocol tcp

More details on the match command is here.

https://www.juniper.net/documentation/us/en/software/junos/cli-reference/topics/ref/command/show-security-match-policies.html

If the policy does not exist yet.  You need to create any address book objects and policies to permit the syslog traffic as described here.

Hello again

 i have two domain-name  used in  the same server syslog (  fr-1vm-syslog03.infra.msv  , fr-2vm-syslog03.infra.msv )  and also i have server dns : addres ip :10.5.11.106

my question  is update   :  Configuring two domain names on client DNS   (    my goal of this mini project ) 

what is the template syslog configured in device  device MX 480 , that i want use two domain name (  search in domain 1  else domain 2 ) in configuration syslog  and also dns 

that allow send all log to remote server   ??  what are commands exact ? 

same toplogie 

i wait a answer from  you to help me

I'm not sure I follow the question.  It seems like you might be asking if the SRX1500 can be the syslog server and collect logs via DNS name from other devices.  The answer is no, the SRX or any Junos device can send logs to a syslog server but cannot be the syslog collector.

You can configure the external syslog server you sent to as a DNS name instead of ip address.
