29: =head1 DESCRIPTION
30:
1.41 andrew 31: Perl access to the telnet interface on Trango APs and SUs.
1.40 andrew 32:
1.41 andrew 33: A handy feature is that it will parse the output from certain commands that is
34: in the format "[key1] value1 [key2] value2" and put those in a hashref that is
35: returned. This makes using the output from things like sysinfo very easy to
36: do.

1.40 andrew 65:
66: It also takes an optional parameter 'Decode'. If not defined it
67: defaults to 1, if it is set to 0, it will not decode the output and
68: instead return a reference to an array of the lines that were returned
69: from the command.

177: These are usually only set internally.
178:
179: =head2 B<firmware_version> - returns the firmware version
180:
181: Returns the firmware version if available, otherwise undef.
182:
183: It should be available after a successful open().
184:
185: =head2 B<host_type> - return the type of host you are connected to.
186:
187: returns the type of host from the login banner for example M5830S or M5300S.
188:
189: Should be available after a successful open().
190:
191: =head2 B<is_connected> - Status of the connection to host.
192:
193: returns 1 when connected, undef otherwise.
194:
195: =head2 B<logged_in> - Status of being logged in to the host.
196:
197: returns 1 after a successful login(), 0 if it failed and undef if
198: login() was never called.
199:
200: =head2 B<login_banner> - The banner when first connecting to the host.
201:
202: returns the banner that is displayed when first connected at login.
203: Only set after a successful open().
204:
205: =head2 B<last_lines> - The last lines of output from the last cmd().
206:
207: returns, as an array ref, the output from the last cmd() that was run.
208:
209: =head2 B<last_error> - A text output of the last error that was encountered.
210:
211: returns the last error reported. Probably contains the last entry in
212: last_lines.
213:
214: =head1 ALIASES
215:
216: =head2 B<bye> - alias of exit()
217:
218: Does the same as exit()
219:

221:
222: Does the same as reboot()
223:
224: =head2 B<save_systemsetting> - alias of save_ss()
225:
226: Does the same as save_ss()
227:
228: =head1 COMMANDS
229:
230: Most of these are just shortcuts to C<cmd(String =E<gt> METHOD)>,
231: as such they accept the same options as C<cmd()>.
232: Specifically they take a named paramater "args", for example:
233: C<tftpd(args =E<gt> 'on')> would enable tftpd
234:
235: =head2 B<tftpd> - The output from the tftpd command
236:
237: Returns a hash ref of the decoded output from the
238: command.

241: successfully changed.
242:
243: =head2 B<ver> - The output from the ver command
244:
245: Returns a hash ref of the decoded output from the

268: $t->remarks($new_remarks);
269:
270: =head2 B<sulog> - The output from the sulog command
271:
272: Returns an array ref of hashes containing each log
273: line.
274:
275: =head2 B<save_sudb> - saves the sudb

296:
297: Returns the output from the eth link command
298:

300: command after it to appear to fail. I am not sure why.
301:
302: =head2 B<su_info> - gets the su info
303:
304: Returns information about the SU.
305:
306: You need to pass in the $suid and it will return the info for that suid.
307:

309:
310: =head2 B<su_testrflink> - tests the RF Link to an su

1321: =head1 TODO
1322:
1323: There are still a lot of commands that are not accessed directly. If
1324: you call them (as cmd("command + args") or whatever) and it works,
1325: please send me examples that work and I will try to get it incorporated
1326: into the next version of the script.
1327:
1328: I also want to be able to parse the different types of output from
1329: commands like su, sudb all and anything else that would be better
1330: available as a perl datastructure.
