Hi, the vendor is Audiocodes,mediant 800 I don't know the other details about the device. We just try to make telnet with perl and get configuration backup to a txt file. it runs show running config command. thanks.	[reply]

The documentation I have found for those devices (here and here) is not very friendly. In any case, they look too sophisticated to lack a setting to disable pagination. What do you get when you run `help` at the CLI? Anyway, supposing pagination can not be disabled, I would try the following ways: 1. You may be able to download the configuration file through the web interface. Even if that means doing some web-scraping, getting the file would be a reliable operation. 2. Those devices support the TR-069 management protocol (a SOAP interface). If it is enabled you could also use it to download the configuration file. 3. Maybe, the file is also downloadable using TFTP or SCP. 4. Finally, you can use some module as Expect or Net::Telnet to send the command to the device and then repeatedly wait for the `--MORE--` prompt and send CRLFs. Then you will have to remove the prompts from the output, but be careful, because it would be easy to mangle the configuration.	[reply] [d/l] [select]

hi salva thanks for your advices. here is the outputs of help command on CLI `Mediant 800> help Use '?' in order to show available commands. 'TAB' can completion Use 'list' to see all available commands Mediant 800> enable Turn on privileged commands exit Exit from current mode help Show available commands history Show a list of previously run co list Available command list nslookup resolve host name ping Ping packets pwd Display current configuration mo quit Disconnect show Show running system information` [download] Could you please give some examples about the usage of Expect and Net:Telnet to ignore --more--? I've made some tests like below but it does not make sense could you please check? `$telnet->print('show running-config'); while( my $line = $telnet->getline() ) { push @lines, $line; $match = $telnet->waitfor(Match => '/\-\-More\-\-$/i'); if ($match =~ /\-\-More\-\-/){ $telnet->print(" "); } }` [download]	[reply] [d/l] [select]

It seems `list` would give you the full list of commands. The problem with your code may be the device not sending a CRLF after the `--MORE--` prompt, so `getline` just stalls waiting for one. Try using the following code instead: `while(1) { my $match = $telnet->waitfor(Match => '/^--More--$/i', Match => '/^Mediant 800 >/i', Mathc => '/.*$/'); last unless defined $match; if ($match =~ /^--More--/i) { $telnet->print(' '); # ignore line } elsif ($match =~ /^Mediant 800 >/i) { # back at command prompt; last; } else { push @lines, $match; } }` [download]	[reply] [d/l] [select]

The command set looks similiar to Cisco's, where the command for setting the page length (and disabling paging) is a privileged command. in your command list, there's an `enable` command. Try to issue this command, which probably will require an additional password, and repeat the `list` command (or try to issue a `terminal pager 0` command.	[reply] [d/l] [select]

Hi Salva; I can get the all the configuration to a txt file thanks, but there is some bad characters in this file like BSBSBS is it backspace? How can I replace it with using perl? I can't do this? thanks	[reply]

Hard to tell without seeing the exact output file. Anyway, that's the reason why using telnet and feeding a pager is usually a bad idea. It is not reliable. There are too many ways the captured output may be mangled.	[reply]

Hi again salva, is there any way to remove empty lines from array? I tried with grep but it doesn't work. thnaks.	[reply]
Re^5: How to pass --MORE-- by salva (Canon) on Feb 17, 2015 at 13:58 UTC
`@lines = grep is_empty($_), @lines;` [download] Where `is_empty` depends of your definition of empty. For instance: `sub is_empty { my $line = shift; $line eq '' }` [download] BTW, even if you may still be facing the same issue, this is a different question. You should open a new thread for it.
