CentOS-6.6 We have a host that has multiple IPv4 addresses aliased to eth0. The primary address is 216.185.71.x and the alias is 192.168.6.x. This host connects to devices on both netblocks without problems. Only default routing is used and it looks like this: #ip route 192.168.6.0/24 dev eth0 proto kernel scope link src 192.168.6.x 216.185.71.0/24 dev eth0 proto kernel scope link src

Hi James, Simply remove the GATEWAY line from the eth0:192 interface config :D Then you'll had only one default gateway. And the source IP to all unknown address will be the routeable one.

Hi Everyone, We rent a CentOS 7 VM from GoDaddy. We received a warning about excessive cpu usage, and a threat to cancel our service. We tracked it down to Apache and someone hammering our web server. The offending host is 59.64.129.175. To err on the side of caution we attempted to block the entire netblock. According to whois data, that's 59.64.128.0-59.64.159.255. iptables -A INPUT

Some lists and emails are distributed via ns1.samba.org. For those of you that use ORBS, you'll find it is blacklisted now. There is no mention of it on the website and it doesn't return a positive when you enter it for testing but it has slipped into the ORBS blacklist somewhere. Samba.org admins may wish to force all ns1 outbound email via another netblock, bringing it up to ORBS only

CentOS-6.5 i86_64 qemu-kvm-0.12.1.2-2.415.el6_5.4 MS-Windows v7proSP1 We have installed a MicroSoft Win7 system as a guest and have joined it to our MS AD domain. The system runs and has internet access. However, the IPv4 address it obtains and the gateway it is assigned are both sourced from the virtual machine host system and not from our AD DC DHCP server. To clarify, the virbr0 IP address

Sub:[LARTC] cbq init for one port on a subnet Hello, We use cbq.init to limit bandwidth. It works great on a per-user basis. Now I''d like to limit traffic from a netblock to the Internet on port 6699. Network is 192.168.0.160 mask 255.255.255.224 eth0 is the gateway eth1 connects the netblock in question Is this the proper syntax; DEVICE=eth0,10Mbit,1Mbit RATE=100Kbit

I have set up a VPN over PPTP on a CentOS server using the DKMS module rpm dkms-0-2.0.6-3.el4 from http://centos.karan.org/el4/extras/stable/i386/RPMS/repodata/repovie w/dkms-0-2.0.6-3.el4.kb.html and kernel_ppp_mppe-0.0.5-2dkms.noarch.rpm at http://pptpclient.sourceforge.net/howto-fedora- core-3.phtml. I have configured the pptpd server on Centos4 to use MS_CHAPv2, 128bit encryption and

This note is essentially a request for a reality check. I use IPFW & natd on the box that provides the interface between my home networks and the Internet; the connection is (static) residential DSL. I configured IPFW to accept & log all SSH "setup" requests, and use natd to forward such requests to an internal machine that only accepts public key authentication; that

I have a three interface network (net,loc,dmz). The internet interface (eth0) has a static IP. Windows machine in the local network (eth1) use DHCP to get IPs from the 192.168.10.0/24 netblock. The Debian machine in the DMZ (eth2) gets a fixed IP through DHCP in the 192.168.11.0/24 netblock. The DHCP server is running on the firewall machine (not ideal, I know, but that''s the way

I've been having some odd problems with samba and it's libsmb/nmblib parts. It seems to be trying to transmit data to the .63 of my netblock, i.e. the IP of the machine would be 24.240.60.20, it'd be trying to transmit to 24.240.60.63. I've changed IPs about 15 times since, and it does it to each different block I change to. If the IP of the local machine got changed to

I been running shorewall with out any problems for several months. But I''ve now run into a problem. Hopefully this will be enough information. I''m running shorewall version 1.4.8. On Fedora core 1.

I am contemplating converting some of our internal networks from routable to private IPv4 address space. I have a question about RIP as implemented under Cisco IOS 12.x. Presently the setting for rip is: router rip version 2 passive-interface [[FastEthernet]]0/0 network aaa.bbb.ccc.0 no auto-summary What I would like to know is how one routes the entire 192.168/16 address space using rip.

I am seeing log file entries like this: IN=eth0 OUT=eth1 SRC=109.74.193.253 DST=x.y.z.34 LEN=122 TOS=0x00 PREC=0x00 TTL=48 ID=49692 PROTO=ICMP TYPE=3 CODE=3 [SRC=x.y.z.34 DST=109.74.193.253 LEN=94 TOS=0x00 PREC=0x00 TTL=53 ID=41330 PROTO=UDP SPT=34679 DPT=53 LEN=74 ] This is found on our gateway host. eth0 is the WAN i/f, eth1 is the LAN i/f. Our netblock is x.y.z.0/24. Can somebody tell me

I am trying shorewall as my previous post With alisias on eth1 loc and 4 pptp client vpns. The odd thing is when I enter one of the vpns in interfaces such as vpn1 it works.

Hi, I would normally post this to the drbd list but it so low traffic/low volume (plus Austria might be asleep right now) I figured i'd ask someone here in case they have gotten drbd working on centos. Right now my system says i'm only the 971st person to even install it... It's been out for years, so likely this just means version 8. But you'll only see a couple of posts

We use a dual homed CentOS-6.3 host for our Internet gateway router.
