Buildings have units. Units have rooms. Rooms have people. I can grab building, room, and people IDs and store them in a session[:variable]. However, when creating a new unit, I need to give that session[:building_id] to ActiveRecord for creation. I''m not sure whether to use hidden fields or do it all in the model ''before_validation'' - in either case I

I have the following scenario. Users have various levels of ability. They can only view and edit their own records (their profile). Their managers can only view and edit their employees records. The regional managers can view and edit only the people in their regions and the corporate headquarters can view and edit all records. There are multiple regions so somebody can be the manager of the

I''m building a 10 branch/1 headquarter network with Shorewall/Linux as gateway on all locations. The TI guy asked me if there is a way to ''cache'' TCP/UDP traffic between them. I crawled on Internet and I only find very expensive solutions for this. Some of them appeared in this comparison article: http://www.networkcomputing.com/showitem.jhtml?docid=1524f5 Does anyone

Hello Guus, thank you very much for your suggestions, I could not dive into it further because I was traveling, but now I have time to reconfigure the network. At first I really like the idea of having 3 Daemons on the headquarter, one for each ISP. The firewall should forward the port 655 from each ISP's public IP Address to my internal server and to the ports 655, 656, 657 respectively,

Hi guys, I was thinking aboiut this for a while: If I have nested resource routes, for example /building/1/floor/2/ room/ 3 (building has_many floors and so on), I have to call the room_path method like this: room_path @room.floor.building, @room.floor, @room Isn´t there a better way to handle nested routes with foreign keys, or can I have this method overwritten somewhere?

Hello I makeing a Domain Controller with Samba (v3.0.33) and LDAP (v2.4). I will install a PDC in the headquarter and a BDC in the subsidiary of the company that I work. The PDC and the BDC will have his own LDAP data base. I just install the PDC without problems and my next step is to install the BDC. I configured the LDAP that work in multi master mode.

I am thinking about a change to our company's phone "layout" and would like to get comments from people who have done something similar. Currently, we have 3 locations - each with their own Asterisk PBX. The corporate office has a PRI. Each remote location has a SIP provider for 5 channels of SIP going to their own PBX. Interoffice calls use the PSTN. Most inbound calls come to

Hi people! I?m a fireman from S?o Paulo Fire Dapartment (Brasil) and I?m encharged to give support to the Computer System of the headquarter.

Hi all, ive been reading lartc howto, im new about traffic shaping/police. As far as red (chapter 9 complete) i saw that first the packet passes at the ingress qdisc, then it passes to the ip stack if the packet is directed to the box or its forwarded (is my case), then it falls to the egress classifier/s. Now, i understand if i have an ipsec vpn at the outside interface, the egress

In the headquarter of my Institution we have some 300 windows PCs, distributed like this: domain1: 100 clients in a consolidated samba 3.0.5-2 domain (RH 9.0) domain2: 20 clients in an incipient samba 3.0.14a-2 domain (FC4) 80 clients to be joined to domain2 without domain: 150 clients beloging to some three workgroups We outsourced the deployment of a LDAP server and we are in the

Another old thread I’m resurrecting; apologies, but I have also been experiencing this issue. I have 10 international remote sites over very lossy WAN links. Getting traffic to them from HQ is a challenge; them trying to talk directly each other over umpteen paths is even worse. They are able to accomplish this (somewhat) because we have a mesh VPN setup with direct site-to-site connectivity, but

Hello, I''ve been using cbq''s "weight" parameter to influence distribution of excess bandwidth among sibling classes. Does htb offer something similar? So far I think that - you either use priorities - then excess bandwidth is offered to higher priority classes first, the rest (if any) is distributed among lower priority classes - or you don''t use

At work, I have 4 branch offices at which I've deployed asterisk. Call termination/origination at each branch office is handled either through a frac PRI or 3rd party SIP provider. Soon, I'll be replacing the legacy PBX at our HQ with asterisk. Each branch office has between 3 and 20 employees, each with their own extension and DID, and at headquarters, we have about 70 people, again

We are planning to install a voip system based on asterisk for 2000-3000 retail locations and up to 6000-8000 sip accounts/users. Instead of setting up a new, centralized PSTN gateway, we are intend to use a CISCO gateway/router of an existing CISCO voip solution in the headquarter and we must able to call all CISCO based voip phones in the headquarter running together with a CCM.

Hi R-users, I have to define a noise level function L and its energy in the various moment of the day by: if time is between 18:00:00 and 23:59:59 then L[j] <- L[j]+5 and W <- 10^((L+5)/10) if time is between 22:00:00 and 05:59:59 ==> L <- L+10 and W <- 10^((L+10)/10) else L=L and W = W Could someone help me to realize this function please? You will find my following

Hi team! At work I have several small branch offices with ~5 PCs each. All PCs are member of a Samba4 domain, whose DCs are on the headquarters (linked by consumer grade VPNs) I want to ship "some small, cheap, reliable and magical device" to each branch, in order to provide just 2 things: * AD replication * File shares That't it, period. Nothing fancy. Suggestions??? What do you

Hi: Can anybody point me to some guidelines about SMB network design or give some advice? Samba HOWTOs are very detailed recipes, but I need some general tips, like if we are serving fish or pasta tonight :-) This is the situation: a WAN with 20 offices with 2 to 30 people in each, plus a headquarter with 50 people, plus the databases and central file servers. The organization grew up on a NT4

I am a Linux sysadmin who has been tasked with developing the phone system for our nonprofit's new US headquarters building. We cannot bring our legacy phone system with us, so I am building this completely from scratch. I have already read "Asterisk: The Future of Telephony" and done a fair amount of googling. I am completely sold on Asterisk, and the new building's
