similar to: Custom iptables rules to drop DNS Amplification Attacks

Greetings all, I''m sure there is probably a very obvious reason for the following problem. However, after much hair pulling, I am just not seeing it yet. As you can see from the trace below, I am not able to complete scaffold generation due to some problem between rails and mysql. I double checked MySQL to make sure both my Ruby user and Root user have full rights to the database.

How can I configure samba4 to be protected against DNS amplification attacks? Is there a way to set the network I want it to be recursive, like in bind9? My samba4 is receiving attacks and googling I found this: http://dnsamplificationattacks.blogspot.com.br/2014/02/domain-gerdar3ru.html -- --------------------------------------- Bruno Vane S.O. do Brasil Telecomunica??es +55 24 99306-8618 |

Hello, Lutz Donnerhacke implemented DNS-Dampening. http://lutz.donnerhacke.de/eng/Blog/DNS-Dampening The implementation is available as patch for BIND9 only. He told me that there is an other method preferred by the nsd developer. It's called "Response Rate Limiting". May one describe the idea behind rate limiting and compare it with Lutz' solution? Thanks. -- Andreas

Hi, I've noticed huge write amplification problem with thinly provisioned logical volumes and I wondered if anyone can explain why it happens and if and how can be fixed. The behavior is the same on Centos 6.8 and Centos 7.2. I have a NVME card (Intel DC P3600 -2 TB) on which I create a thinly provisioned logical volume: pvcreate /dev/nvme0n1 vgcreate vgg /dev/nvme0n1 lvcreate

I give up and need help! I won''t add to the confusion by showing all the combinations I have tried unsuccessfully... and yes, I''ve read FAQ2 and FAQ2a many times! When googling the subject of this post there are many answers that boil down to using the same three iptables rules, two of which use nat. I won''t repeat them here. I don''t want to risk mixing

Hi, I use shorewall-4.5.4 + lsm-0.143 and it does not seem to work as expected... When all providers are up, everything seems fine. When one goes down, lsm says "link <provider> down event"... and it seems ok but we then experience some problems such as a few unreachable sites, DNS problems... If I remove the downed provider from all confs and restart, everything works again.

Hi, I want to configure QoS in my shorewall conf but I have a doubt. Now I am using tcrules with prerouting and with the file providers, like this. 2:P 192.168.0.11 0.0.0.0/0 tcp 25 So, with this way I route my smtp traffic with my provider number 2. Well, now I want to configure QoS with tcclasses and tcdevices, but if I do that I need to use the MARK in the tcclasses So, how

hi, while stopping shorewall 4.5.21.2 on a debian7 box with the ADMINISABSENTMINDED set to no in shorewall.conf, the connections on vlan tagged interfaces that were active before the shorewall stop command was executed are not terminated as it is for the firewall and other interfaces! when the firewall is stopped as expected new connections on vlan tagged interface are refused but even

Hello, I''m using shorewall-4.5.16 with centos5. The dhclient stores the lease information on the /var/lib/dhclient/dhclient-<DEVICE>.leases file. The /var/lib/shorewall/firewall script has the function detect_dynamic_gateway that detects the gateway based on the leases file. The code in the function is: detect_dynamic_gateway() { # $1 = interface local interface

I''m trying to use my VPS server (single interface of course) as somewhat of a VPN gateway to my other location (which is not accessible directly from some places) where the openvpn server is running, and am kind of lost as to what to try next. I tried a redirect rule, but apparently shorewall didn''t like that (it just failed to start). I tried adding the rules via
