globalset < attribute > < value >
set global attributes
globalset will change the < attribute > of the teamspeak instance and set it to < value >.

These are the currently available attributes and their values:

attribute value
hoster_gfx_url text

Note: This is a URL to a image to be displayed to connected clients, changes to it will only be visible to clients connecting after you changed it - and the changes will not be
saved to the server.ini, meaning will not be permanent over a server restart.

allowedclientnamechars text

Note: This restricts what characters you will allow in nicknames. Users with disallowed characters will get a message when they connect.

disallowedclientnamechars text

Note: This is the little brother of allowedclientnamechars - characters you set here will not be allowed in nicknames, clients will be informed what characters they are using that are not allowed on this server. The default setting for this will be "()[]{}" to prevent flag faking.

Net::Telnet::Netscreen is a Perl module that interacts with a Netscreen firewall.

Net::Telnet::Netscreen is mostly a pure rippoff of Net::Telnet::Cisco, with adaptations to make it work on the Netscreen firewalls. It also has some additional commands, but for basic functionality, see Net::Telnet and Net::Telnet::Cisco documentation.

use Net::Telnet::Netscreen;

my $fw = new Net::Telnet::Netscreen(host=>192.168.1.1); $fw->login(admin,password) or die $fw->error; $fw->enter_vsys(wineasy.no); print "We are now in: ".$fw->current_vsys."n"; my %vsys=$fw->get_vsys; foreach $key (sort (keys %vsys)) { print $key,=, $vsys{$key},"n"; } print @results;

Before you use Net::Telnet::Netscreen, you should probably have a good understanding of Net::Telnet, so perldoc Net::Telnet first, and then come back to Net::Telnet::Netscreen to see where the improvements are.

Some things are easier to accomplish with Net::SNMP. SNMP has three advantages: its faster, handles errors better, and doesnt use any vtys on the router. SNMP does have some limitations, so for anything you cant accomplish with SNMP, theres Net::Telnet::Netscreen.

New methods not found in Net::Telnet follow:

enter_vsys - enter a virtual system

Enter a virtual system in the firewall. parameter is system you want to enter . You may enter another vsys even if you are in a vsys. Note that we will save your changes for you if you do. (only works for ns-500+)

enter_vsys - exit from the level you are on

exit from the vsys you are in, or from the system if you are on the top. takes one parameter. if you should save any changes or not. (only works for ns-500+)

current_vsys - show current vsys

return the vsys you currently are in. returns blank if youre not in a vsys. (only works for ns-500+)

get_vsys - return vsys.

returns a hash of all the virtual systems on your system, with system ids for values (only works for ns-500+)

ha_mode - return high availability mode.

return the HA mode, if your system is in a HA cluster, or false if it isnt.

ping - ping a system. Returns percentage of success (0-100).

$sucess=$fw->ping(192.168.1.1);

exit - Exit system

use this command to exit system, or exit current vsys

getValue - Set a value from the box.

Will return a value from the firewall, or from the vsys you are in, if you arent in root.

setValue - Set a Value in the box.

Set a value in the box, returns true if set successfully.

lastPrompt - Show the last prompt returned.

Shows the last prompt returned by your netscreen device.

lastCmd - Show the last command executed.

Shows the last command executed on your netscreen device.

The ser2net daemon allows telnet and TCP sessions to be established with a units serial ports. Note that ser2net supports RFC 2217 (remote control of serial port parameters), but you must have a complient client. The only one I know it is kermit application (http://www.columbia.edu/kermit).
Enhancements:
- dataxfer.c, devcfg.c, devcfg.h, ser2net.conf, ser2net.8: Added a s banner token for printing out the serial parameters.
- ser2net.conf: Cleaned up the ugly banner3.
- Makefile.am: Add ser2net.init to EXTRA_DIST.
- configure.in: Move to version 2.3.

Netwox is a toolbox that helps to find and solve networks problems.
Main features:
- sniff, spoof
- clients, servers
- DNS, FTP, HTTP, IRC, NNTP, SMTP, SNMP, SYSLOG, TELNET, TFTP
- scan, ping, traceroute
- etc.
Netwox contains 217 tools using network library netwib. Some tools are only a simplified implementation, while others are very sophisticated.
Netwox project is available under the GNU GPL License.
Netwag is a graphical front-end to netwox.

Perl MUD Client project is a text-based MUD client supporting SSL, ANSI, telnet negotations, and MCP.

PMC is a text based mudclient written in Perl 5. It utilizes GNU readline, supports SSL, local editing support through MCP (MudClientProtocol), full telnet negotiation support and of course ANSI support if your terminal supports it.

Unlike other mudclients with input line editors/history, it also supports the telnet character mode, which enables it to use e.g. fullscreen applications within a mud (like the xeditor found on some LP Muds).

tcptunnel is a simple TCP tunnel written in Perl.

Also is a versatile tcp tunnel. The tcptunnel uses:
- tunnelling through a firewall or proxy
- redirecting tcp connections to other ports or machines
- debugging tcp connections in-place
- packet sniffing

The tcptunnel listens on local port < port > and when a connection is made it connects the other end of the tunnel as follows:
a) With no proxy specified, it connects the other end
to < srvport > on < srv >.
b) With a proxy, it connects to < srvport > on < proxy >.
It then directs the proxy to telnet to < srv >, and then it connects the ends of the tunnel.

Lynx is a fully-featured WWW client for users running cursor-addressable, character-cell display devices (e.g., vt100 terminals, terminal emulators running on PCs or Macs, or any other character-cell display).
Lynx will display HTML documents containing links to files on the local system, as well as files on remote systems running HTTP, HTTPS, gopher, FTP, WAIS, NNTP, finger, or cso/ph/qi servers, and services accessible via logins to telnet, tn3270, or rlogin accounts.
Enhancements:
- Several unrelated fixes and improvements were made for configuring, packaging, FTP, SSL, etc.
