Sorry to ask such a basic question: I have a * box with 2 nics in the following setup: Internet | 192.168.5.253 (firewall) | 192.168.5.xxx network (gw 192.168.5.253) | 192.168.5.10 (* nic 1) 192.168.6.10 (* nic 2) | 192.168.6.xxx network The netmask for both networks is 255.255.255.0 The 192.168.6.xxx networks has a 48 port switch solely for the use of cicso 7940 phones, the 192.168.5.xxx is

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

I have this problem: there is a subnet 192.168.6.0/24 and the gateway is 192.168.6.1 which has also another nic 172.21.13.123 which belongs to subnet 172.21.13.0 where the PDC of NT-domain is. GW does NAT and it causes that computers/users in subnet 192.168.6.0 cant logon to NT-domain. Is it possible to put Samba in GW machine so that it can be a backup domain controller in NT-domain and it uses

Hello Everyone. We have: Asterisk 1.4.21.2 zaptel-1.4.11 libpri-1.4.5 Sangoma A101D Connected to a PRI Cicso 7960G phones (About 30 of them) We have a problem with dropped calls that has going on for a long time. We get up to 5 dropped calls on a bad day. They all seem to be incoming calls. I have a recording of what my users report a dropped call sounds like right before it drops

Hi Folks, Prior to upgrading my Zaptel sources everything was working fine. I have a X100P connected to my analogue line. The handset port of the X100P is connected to my desk phone's line 2 input. When the analogue line rings I see the CID on my line 2 but not from Asterisk on line 1 via the Cicso ATA. This used to work fine until I upgraded the sources. I get this when watching the

A number of weeks ago I had huge help from many of you configuring routing on a server with multiple Internet facing nics. Thanks for all of your help!!!! I am still having a routing issue that I am hoping someone can help me tweek. This server, besides acting as our gateway to the internet, is also our web and email server. The server has 4 nics. Two are connected to the internet and the

I have the following configuration on one of my file shares using 3.0.10. And I have found out that some users can get files off of the server and some cannot. The users that cannot connect get the error. "Incorrect password or unknown username" Connect as; Password: After playing around awhile I added one of the users to the computer with useradd. They were then able to

I have a three tinc server setup, similar to "4.3 How Connections Work" using the configuration mostly likehttp://ostolc.org/site-to-site-vpn-with-tinc.html The clients (Ubuntus, Debians and Windows 10s) can all ping (and SSH) to each other remotely. As far as that is concerned it's working great - thanks so much for some great software. However, on each of the Tinc servers (A and

I'm trying to setup my first Asterisk setup on a CentOS 5 installation on VMWare Workstation 6. Got two Linksys SPA941s working fine. But X-Lite softphones can't answer phone calls, and when one of them calls on of the Linksys phones they "connect" but neither party can hear hear the other. I noticed that the Linksys phones are connected via Native bridging while the

Hi guys, I realise this is problaby more basic than what this list is intended for, but I had no luck elswhere. Short version: I have previously used these lines on a server with two network interfaces, two public IPs, and one common default gateway, to make sure that connections coming into eth1 is replied to replied to via the same interface. eth0 is 196.xx.xx.35, eth1 is 196.xx.xx.54,

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.

I am having an issue with a new samba setup. My gateway server (H1 - the new setup) is running Samba and acting as my networks wins server. It also houses my email and web server. It is connected to a private network to another server (H3) running Samba acting as my main file server. The issue that I am experiencing is that H3 can view our webpage that is hosted on H1 but my Windows machines

I need help setting up a basic routing between two nic's on my CentOS desktop. I thought I'd understood the basics, but ... I don,t want a nat router, just packets forwarded back and fort. This is what I thought would do the trick, but didn't. Can someone please give me some pointers or links so I can get this right. # echo "1" > /proc/sys/net/ipv4/ip_forward # route

Hello! I need assistance to solve my problem related to traffic shaping based on the user ids. The problem: each unix user (of the linux host) has to be limited with incoming channel (internet) bandwidth. I need this to implement internet access solution based on ltsp (http://www.ltsp.org). As far as I know the best way to shape traffic in linux is CBQ. But there is no filter based on unix

Hi all, I have a strange setup I am trying to get working. Initally I thought I could set it up by just setting up the correct routes. However after thinking about it I have convinced myself (maybe incorrectly) that I most likely need some sort of advanced NAT/routing setup. Below is a description of the networks involved: Local net (192.168.101.0/24) | | Linux machine eth1

Hi, I'm trying to backup from one machine to the other (automatically via cron) using rsync and ssh password-less public key authentication.

Hi everyone, samba 2.2.5 The server I'm using has 2 interfaces so using the interface parameter I'm telling samba to use eth0 but for some reason when I do netstat it is listening on eth1 interface = eth0 (the IP is 192.168.6.10) netstat -an udp 0 0 138.79.161.225:137 0.0.0.0:* udp 0 0 0.0.0.0:137 0.0.0.0:* udp 0 0 138.79.161.225:138
