Free lan software for linux

OSGlobeLAN project is a Web portal for LAN parties, featuring a seat map system, registration, and more.
Enhancements:
- A lot of changes have been made, but this release is primarily to announce that work on the pre-1.0 codebase of OSGL has been stopped, and will no longer be maintained.
- Serious security-related issues might be fixed, but all focus is now on the 2.0 codebase.

phpLanParty project is a Lan Party registration application.
phpLanParty is an application to administer Lan Parties.If you host gaming sites, parties, tournaments, or the like, you may be interested in using this utility.
Main features:
- Its fast, easy, and easily modified to suit your needs.
- Being written in PHP, is multi-platform. Although its only been used and tested on Linux, it should work well on other Unix-like platforms, and probably the Win32 platform, provided the required packages (below) are installed.

LMS (LAN Management System) is the integrated system of networks management designed for various size internet providers (ISP).

That software writed in PHP, Perl and C, works with variuos database systems.

Run a web server inside LAN is a simple script to run a WWW server inside a Local Area Network. Run a web server inside LAN script assume all iptables features are compiled statically in the kernel, or all modules are loaded.

Otherwise you may encounter some surprises trying to utilize the more featureful and creative commandlines that Ive come up with.

Sample:

#external and internal interfaces
EXT=eth0
INT=eth1

# clear everything, and create my cascading chains
iptables -F
iptables -N e0
iptables -N tcpin
iptables -N udpin

# e0 is the name of our chain for eth0
iptables -I INPUT -i $EXT -j e0

# OUTPUT Chain
iptables -A OUTPUT -o $EXT -j DROP -p icmp --icmp-type ! echo-request

# remote gnutella queries were really pissing me off one day
# iptables -A OUTPUT -o $EXT -j DROP -p tcp ! --syn --dport 6346
# iptables -A OUTPUT -o $EXT -j DROP -p tcp ! --syn --sport 6346

# $EXT Chain
# a single rule to accept SYN Packets for multiple ports (up to 15)
iptables -A tcpin -j ACCEPT -p tcp --syn -m multiport --destination-ports 873,993,995,143,80,113,21,22,23,25,53

# stateful connection tracking is wonderful stuff
# ESTABLISHED tcp connections are let through
# If we send a SYN out, the ACK is seen as RELATED
# then further communication is accepted by the ESTABLISHED rule
iptables -A e0 -j ACCEPT -m state --state ESTABLISHED
iptables -A e0 -j ACCEPT -m state --state RELATED

# certain ports I simply DROP
iptables -A tcpin -j DROP -p tcp --syn -m multiport --destination-ports 6346,139

# UDP rules...
iptables -A udpin -j DROP -p udp -m multiport --destination-ports 137,27960

# I run a DNS server, so we must accept UDP packets on port 53
iptables -A udpin -j ACCEPT -p udp -m state --state NEW --destination-port 53

# lets log NEW udp packets on ports 1024:65535, then let them through
iptables -A udpin -j LOG -p udp -m state --state NEW --destination-port 1024:65535 --log-level debug --log-prefix UDPNEW --log-ip-options
iptables -A udpin -j ACCEPT -p udp -m state --state NEW --destination-port 1024:65535

# lets log NEW tcp packets on ports 1024:65535, then let them through
iptables -A tcpin -j LOG -p tcp --syn --destination-port 1024:65535 --log-level debug --log-prefix TCPNEW --log-tcp-options --log-ip-options
iptables -A tcpin -j ACCEPT -p tcp --syn --destination-port 1024:65535

# lets log INVALID or NEW tcp packets on priveleged ports, then DROP
# (remember I have certain ACCEPT rules higher up the chain)
iptables -A tcpin -j LOG -p tcp -m state --state INVALID,NEW --destination-port 1:1023 --log-level warn --log-prefix TCPPRIV --log-tcp-options --log-ip-options
iptables -A tcpin -j DROP -p tcp -m state --state INVALID,NEW --destination-port 1:1023

iptables -A e0 -p tcp -j tcpin
iptables -A e0 -p udp -j udpin
iptables -A e0 -j LOG --log-level debug --log-prefix NETFILTER --log-ip-options -m state --state INVALID,NEW
iptables -A e0 -j DROP

# NAT Rules
# I run a web server inside...
iptables -t nat -A PREROUTING -p tcp -i eth0 --dport 80 -j DNAT --to-destination 192.168.1.4:80

WANem is a WAN Emulator, meant to provide real experience of Internet, during development and test on a LAN environment. Typically application developers develop applications on a LAN while the intended purpose for the same could be the client is accessing the application by WAN or even the internet.

WANem allows for the application development team to setup a transparent application gateway which can be made use to simulate WAN characteristics like Network delay, Packet loss, Packet corruption, Disconnections, Packet re-ordering, Jitter, etc.

WANem allows for WAN network characteristic emulation and thus allowing for applications to be tested in a realistic WAN environment before they are moved into production.

WANem is a combined development strategy where it hooks into the Linux kernel for performing network emulations and provides GUI to make it simple to use. Remastering of Knoppix Live CD makes it even more effective as it becomes platform independant.

LarryMessenger is a simple to use and easy to install Instant Messenger. It is Open Source Software and is hosted as an Open Source Project at SourceForge.net

It is published under the GNU General Public License

You can download all available Source Codes, Binary Releases and Documentation from theLarryMessenger Summary Page at SourceForge.
The Version Alpha02_1 Version will be out soon and provides possibilities to exchange text messages in a LAN with no need for a central Server or a Internet Connection and enables the user to querry the ICQ and AIM Messaging Network.

Next Versions will include support for Proxy Server, MSN and the Jabber Protocol.

If you want to join the Project as a developer visit our SourceForge Page. You will find there all necessary informations.

If you got a list of features you are missing, please fill in Feature Requests at SourceForge.

SafeRelay is a certificate authority center, based on OpenSSL, for network administrators who want to deploy certificates on a LAN (local area network). SafeRelay is written in CURSEL.

You may be thinking of using TLS/SSL and certificates on your LAN for activities like:

configuring intranet web servers to use HTTPS instead of plain HTTP
making LAN users connect over IMAP/SSL or POP3/SSL to your mailserver
letting your LAN users connect to your Sendmail SMTP server using certificate client authentication
having LAN users sign or encrypt their email with S/MIME
client authentication based on certificates for intranet HTTPS webservers

The basic idea is that users tend to forget to make a backup of their certificates.

If the PC of the user crashes, the private key and certificate, can be recovered, from the diskette, by the user without help or intervention from the system or network administrator.

If the user has multiple PCs (e.g. a laptop and desktop), it suffices to simply import the certificate from the diskette on both PCs.

If the diskette is lost by the user, or stolen by another user, or if the diskette suffers from a media error, a new diskette with a new keypair must be prepared for the user.

In any case, by giving the user a diskette with a certificate, the user immediately receives a backup. Any tangible medium would also work. In fact, SafeRelay could allow you to use "cdrecord" and a CD-RW drive instead. For important keys and certificates, you could copy the contents of the diskette onto a read-only medium such as a CD.

ACM is a LAN-oriented, multiplayer aerial combat simulation.
