similar to: ip route nat madness.

Dear all, I have a server with 4 ethernet port interfaces. Also, I have four clients that will connected directly (cross-cable) to one-by-one of each port ethernet interfaces of my server. |--SERVER--\ | eth0-- ------------------ client A | eth1-- ------------------ client B | eth2-- ------------------ client C | eth3--

Greetings routing folks, I want to use the netmask 255.255.255.255 to insulate (not quite isolate) machines on a shared subnet from each other. This works just fine on win XP, but Linux iproute will not acccept the gateway address in one step -- neither on the command line nor via DHCP: Here''s the interface, set up with a netmask of /32: # ip addr ... 2: eth0:

Could you please send me the output of command "sysctl net.ipv4.ip_local_reserved_ports". Apart from output of command please send the logs to look into the issue.

Hi, I have tried on my host by setting corresponding ports, but I didn't see the issue on my machine locally. However with the logs you have sent it is prety much clear issue is related to ports only. I will trying to reproduce on some other machine. Will update you as s0on as possible.

Me and my son are running Tinc over 5 nodes, 3 of them got public address and we using them as server. Each node has its own Lan subnet 192.168.0.0/24. Originally we ran network on Openwrt routers with Tinc many years without any problem, but due to limited RAM on routes and change of one router to not Openwrt supported model, we decided to transfer Tinc installation on Raspberry Pi-s in LAN.

Hi, I am able to recreate the issue and here is my RCA. Maximum value i.e 32767 is being overflowed while doing manipulation on it and it was previously not taken care properly. Hence glusterd was crashing with SIGSEGV. Issue is being fixed with " https://bugzilla.redhat.com/show_bug.cgi?id=1454418" and being backported as well.

Thanks Gaurav! 1. Any time estimation on to when this fix would be released? 2. Any recommended workaround? Best, Guy.

Hello Everyone, I have gone through a few really good tutorials from the OpenSIPS site, Asterisk resources etc.. The unanswered question (and final piece of our puzzle) is if it's possible to have a register free environment in an OpenSIPS/Asterisk integration. Most approaches have OpenSIPS relay the UA's REGISTER request to Asterisk which has "host=dynamic" set for the

If you have a working proxyARP setup, will you please post it? I''ve tried to insert a Linux box between the DSL connection and the switch, but I''m getting nowhere. Everything works correctly when all the servers in this network use the switch to get to the DSL. Any box directly connected to the DSL also works correctly. http://www.sjdjweis.com/linux/proxyarp/ makes it sound

Hi, I have a gluster (version 3.10.2) server running on a 3 node (centos7) cluster. Firewalld and SELinux are disabled, and I see I can telnet from each node to the other on port 24007. When I try to create the first peering by running on node1 the command: gluster peer probe <node2 ip address> I get the error: "Connection failed. Please check if gluster daemon is operational."

https://review.gluster.org/#/c/17494/ will it and the next update of 3.10 should have this fix. If sysctl net.ipv4.ip_local_reserved_ports has any value > short int range then this would be a problem with the current version. Would you be able to reset the reserved ports temporarily to get this going? On Wed, Jun 14, 2017 at 8:32 PM, Guy Cukierman <guyc at elminda.com> wrote: >

Hi, I'm currently experimenting with the mod_evasive module for Apache, to protect the server against potential DoS attacks. Here's what I did so far. # yum install mod_evasive Don't touch mod_evasive's default configuration, just restart Apache. # systemctl restart httpd The package includes a test.pl script supposed to launch a testing DoS attack. Unfortunately this

Thanks, but my current settings are: net.ipv4.ip_local_reserved_ports = 30000-32767 net.ipv4.ip_local_port_range = 32768 60999 meaning the reserved ports are already in the short int range, so maybe I misunderstood something? or is it a different issue?
