Hello. I wonder how just correct couple of spdadd commands like spdadd 192.168.1.0/24 192.168.2.0/24 any -P out ipsec esp/tunnel/10.1.0.1-10.2.0.1/require; spdadd 192.168.2.0/24 192.168.1.0/24 any -P in ipsec esp/tunnel/10.2.0.1-10.1.0.1/require; makes _routing_ of packets from 192.168.1/24 into 192.168.2/24. If I understand correctly how it works on *BSD, these commands with make already

I have a squid proxy running transparently, so in my firewall script I run the following fairly early: iptables -A PREROUTING -t nat -i $LAN -p tcp -m multiport --dports 80,443 -j REDIRECT --to-port 3128 This is a multihomed server so after this change the masquerading was removed (as only web access on the lan side of this server was needed). I now need to masq cleanly one device so that it

Solution is really simple. Since this server is dual-homed ( 2 nic's ), i suggest setup advanced routing tables. The short version of howto setup. edit /etc/iproute2/rt_tables and Add : 10 OfficeLan 20 InternetWan Lookup the routing tables: ip route show table OfficeLan ip route show table InternetWan The default gateway's is to the internet. ( change ethX to you network interface

I have a dual-homed firewall. It has 2 Internet connections, provided by different ISPs (each with an associated IP address). The 2 Internet connections are connected to the same physical interface. The 2 Internet connections do NOT have equal bandwidth How do I configure the SNAT/MASQ and ensure sharing of the gateways with the correct ratio of usage and with the correct source IP address? I

On the Ubuntu 14.04 host, it fails 2 of 8. The log is attached. Additionally there are other weird differences, like /etc/passwd and /etc/shadow and many other /etc

We are planning on moving a large amount of Exchange mailboxes to UNIX mbox format. My question is, does anyone know of any projects out there or of any tools that can assist in this conversion? Thanks Josh

Hi I have been searching for commands to "debug" netgroup membership. I am using netgroups provided by ldap. I can do a ldap query but it seems a bit unwieldy to do. I have found a package on ubuntu called ng-utils https://launchpad.net/ubuntu/jaunty/+source/ng-utils/0.7-1 which does what I require and compiles very easily. It contains two commands netgroup and innetgr to query netgroup

Hi All, I'm wanting to tell my centos box to get a dynamic ip via cli. I know I can do "ifconfig eth0 up", or "ifconfig eth0 191.168.100.35 netmask 255.255.255.0", but, how do I tell it to send the dhcp 0.0.0.0 broadcast to the DHCP server? Cheers. Mark Sargent.

Hi, I recently downloaded and burned the 5.4 DVD ISO. All my machines are now running 5.4, but these are installs I performed with 5.0, 5.1, 5.2 etc. and then progressively upgraded. Now I had to use 5.4 because a friend's laptop, a brandnew Fujitsu Esprimo Mobile, refuses to boot anything under 5.4. After a fresh install of the base system, first thing I do is 'yum update' with

at http://wiki.openpbx.org/tiki-index.php?page=Easy+route+to+building+OpenPBX.org there is the following adduser command: adduser --no-create-home --ingroup openpbx --disabled-password --disabled-login openpbx This does NOT seem to be the right format for Centos. So far, using man, I have come up with; adduser -M -g openpbx What else do I need?

It's half a nice Saturday later and many attempts have brought no satisfaction. Maybe this can't be done. I'm trying to write a function which, when called from one function execute in another. In itself, that's not the problem. Rather, there's one built-in variable which is evaluated in the function definition and it's value is then set (too early). Here's the one

This is an issue that I have been having with one of our production servers for a couple of months, just out of no where /var goes to read only. There aren't any errors that show up in /var/log/messages nor dmesg, I checked to make sure that the drives on error option is set to continue and there isn't anything as far as I can tell wrong with the disks. Also there is plenty of disk space.

I noticed in 4.92 there is no disabling selinux at install. It is now a firstboot option which then requires a reboot. Is there anyway to disable selinux at the boot install prompt so after the firstboot screens it wont reboot again? I presently install with "linux askmethod" so I can select NFS install. Thanks, Jerry

I have been delving into how to get this HP NC4010 to suspend. I think the practice of just closing the unit for 15+ min inside my backpack as I move to the next meeting is what cooked my drive... So it seems that Debian users have been successful with APM: http://www.proulx.com/~bob/nc4000/ and http://www.gag.com/~bdale/nc4000/ So my Centos related questions are: I need to turn acpi=off

Hi there, This post has also been posted in the Hardware and General forums but I thought it might be wise to post it here as well! My CentOS 4.3 (upgraded from CentOS 4.2 installed from Linux Magazine's April 2006 issue) server is rebooting spontaneously (over and over again). It started while I was copying from USB-device (iPod) to another USB-device (Freecom Portable-Hard-disk) but it

How do I configure my DHCP client to restart Shorewall when it obtains a new IP address? Blake

Hi there, I just got a new machine with Redhat Enterprise Workstation and samba 3.0.0-14 pre-installed. I am trying to connect it to my existing network which has a redhat v8 samba v2 PDC controlling 16 or so win2k and winxp machines. In the nmbd log I get this error 3 times every 5 seconds or so: nmbd/nmbd_packets.c:process_nmb_request(1448) process_nmb_request: Multihomed registration

I have a location using a CentOS 5 server that's multihomed running Asterisk and iptables for internal web access. Recently some sales people got busted surfing some explicit content so the owner wants something in there to block this. I had heard of Dans Guardian and am reading about what's involved here but just wanted an opinion on what's the best solution for this. NTLM silent

Hello: I am currently planning to divide our network in smaller subnets. Our central server is a Samba AD DC File Server also acting as DC. My plan is subnet our current network, add a new interface for each subnet in the Samba File Server and configure it to listen in all new interfaces. Questions: 1 - Does this multihomed configuration have any drawback, specifically because AD relies
