Free hub software for linux

Open DC hub is a Unix/Linux version of the hub software for the Direct Connect network. Direct Connect is a file sharing network made up by hubs, to which clients can connect.
Once connected to a hub, the user can search for files on the hub or the network, or browse files of other users connected to the hub.
Main features:
- Searching for files
- Connecting to users, both in active and passive mode
- Messaging in open chat
- Private messaging
- Registering users
- Kicking users (for OP:s)
- Banning users (for Admins)
- Uploading hub address and description to public hub list
- Hublinking, which makes it possible to search on other hubs connected to the network
- Administration of the hub from chat
- Scripting (In Perl)
The hub is run as a daemon, i.e, it runs in the background. Its administrated through a tcp connection, for example with telnet, which makes it possible to administer remotely, given that the user has the administration password. Its also possible to administer the hub directly from the chat in Direct Connect.
The software should run on all POSIX compliant operating systems, but the main testing has so far been done on GNU/Linux-x86 and Solaris-Ultrasparc. Please tell me if you fail or succeed in running it on other platforms.

DSHub is a hubsoft for Direct Connect Network. DSHub project uses the ADC protocol currently in development by Jacek Sieka and DC DEV. ADC is the future of DC++ network.

- added drop command , a kick with no reason and 0 ban time;
Kick Command:
- Kicking in DSHub is very simple now.
- Classic kick:
kicks just a user out in flames, with a kick_time temporary ban, default 5 minutes.
- Extended kick has way more advantages and can be used very efficiently with a large hub.
- Extended kick features:
- Kicking users that match a certain regular expression:
- Example: !kick [RO].* -- this command kicks all users that have their nick starting with [RO]
- Example: !kick .. --this command kicks all users with 2 letter nicks
- This type of kick accepts just any regular expression.
- Kicking users that have their fields checked:
- Example: !kick share, < , =, !
- And a list of possible fields : share, sl (slots), ni (nick length),su(supports, accepts only = or !, example: !kick su=tcp4),hn(normal hubs count),hr(registered hub count),ho(op hub count),aw(away, 1 means normal away, 2 means extended away),rg (1- registered, 0 otherwise, registered means not op),op ( 1 -op, 0 - otherwise , op means it has key).
- created a kick and ban function for easy call from commands;
- done almost all that kick stuff, for share slots and su, still need to do for rest;
- added a debug message, please ignore, or if you figure it out, report to me;
- modified share kick, to be in megabytes;

Kahuna is a KDE application to manage 3com SuperStack PSHub 40s. It provides a load/save function for your favorite hubs. For communication kahuna uses net-snmp 4.2

Aimwatch is a packet sniffer designed to reconstruct AOL Instant Messenger and ICQ information by passively collecting packets from the network.
Main features:
- Messages and Chats
- Buddylists
- AIM Client details
- Login information
- Multiple connections sorted by IP or screenname
- Full interpretted packet dissections of protocol data
- Raw hex views of packets
Packets can be read live from the network or from a file saved in libpcap/tcpdump format. To be able to collect packets from connections between remote machines, you either have to be on a hub (non-switched) network, physically located between the IM client and server, or use other tools to redirect packets through your machine.
Currently this project requires a Linux operating system (or compatible), with the libpcap, libxml2 and GTK+ 2 libraries installed. Ill try to make a binary available with the next version. A text-only interface will be created in the future. A Windows port may also be made, but not this month.
The new design uses an XML file to describe the protocol. The file is read when the program is started and packets are dissected with a dynamic tree created in memory. This allows new packet dissection information to be added to the program without having to recompile or understand the source code.

Cheops is an Open Source Network User Interface. It is designed to be the network equivalent of a swiss-army knife, unifying your network utilities. Cheops is for the network what a file manager is for your filesystem.
Main features:
- Organize your network into convenient pages so you can place relevant portions together, and quickly go to a specific area or specific network.
- Cheops can optionally determine the OS of hosts on the network, selecting appropriate icons for them.
- Cheops can show you the routes taken to access areas of your network. (This feature is designed for larger networks, with routers, subnets, etc. If you only have a simple LAN where all your hosts are connected with hubs, then itll just draw a bunch of lines between you and the other computers) This mapping not only makes heirarchy clearer, but can show unusual routing issues, like this unusual router triangle. Unfortunately, you have to place the machines yourself, but cheops handles the interconnections.
- Right clicking on a host quickly shows you a list of common services it supports, and rapid, easy access to them.
- For large networks, you can view the network with smaller icons, or even as a simple list of networks. Layout is arrangeable by domain, hostname, IP address, etc and searching is supported in both iconic and list formats.
- Cheops includes a generalized TCP port scanner to see what ports on your network are in use.
- Retrieve version information for certain services, to be sure any given host is up-to-date with the latest revision of its services.
- Cheops is highly configurable both through text-based configuration files and through a graphical "Options" dialog box.
- Cheops includes a simple integrated SNMP browser, including write capability, using the UCD SNMP library. Cheops also supports a plugin interface, which includes support for SNMP plugins, similar in concept to those of HP Openview.
- Cheops can monitor your critical servers, and immediately notify you through its event log, standard e-mail, and soon via paging, when things go wrong. Know exactly whats up or down, and just when problems occur.

Tvheadend 2.4 brings users the convenience of a streaming server/relay which supports a variety of sources and multiple output formats.

Together with powerful DVR (Digital Video Recorder) features, an advanced EPG and a web-interface it can be used as a TV distribution hub in your home.

GNU Sauce is an anti-spam server. SAUCE (Software Against Unsolicited Commercial Email) is an SMTP server that sits between the Internet and your actual mail software. It was originally written to help in the fight against spam, but it also helps encourage good configuration and administration in general.

SAUCE has various tactics for DETECTING incoming spam:


Extremely aggressive checks on incoming email and its sources. If any problems are discovered the mail is not accepted.
Spambait addresses: when mail is sent to a bait address its sources are blacklisted.
Mail from previously-unknown sources is delayed to give them a chance to try a bait address or get their account cancelled.

Pros:

SAUCE is very sucessful. It can cut spam by an order of magnitude.
Administrators using SAUCE have to deal with much less bounced mail.
SAUCE never bounces legitimate mail from correct, non-spamming sites.

Cons:

Most spam sources are misconfigured, but many other sites are too, and SAUCE will bounce their mail. SAUCE is not for you if clueless strangers often send you mail thats important to you.
SAUCE delays mail from new senders and sites (configurable, though).
SAUCE is something of a resource hog.
SAUCE is hard to install, especially if youre not using Debian.
SAUCE is controversial, because it deliberately rejects mail for technical deficiencies which wouldnt make it undeliverable.

SAUCE is not a users mailer. It must be installed on a mail hub by the system administrator. It needs existing SMTP software, which must have standard anti-spam features such as relay prevention, checking recipients during the SMTP conversation, etc. Currently you must be using Exim, though support for other mailers could be added.
