Topic: dhcpd.conf expand-template error?

[kryptos]

Hello,

I just brought this problem if mine. I need to tweak some configuration on dhcpd.conf to satisfy what I need on my network. I need to redirect some of the network station to use a different gateways as the current dhcp gives out while others uses the default gateway. Basically I have created a new custom template from /etc/e-smith/templates-custom/etc/dhcpd.conf and from there create this file 99group

Code: [Select]

group {
        option domain-name "vpnisl2";
        option routers 192.168.102.2;
        option domain-name-servers 192.168.102.2;
        host lab {
        hardware ethernet 00:24:82:4C:5b:ce; fixed-address 192.168.102.4;}
}


Then I expand it by: #expand-template /etc/dhcpd.conf

And I got this error after

Code: [Select]

Can anyone explain why I have this error?

hi

Code: [Select]


$OUT .= "group {\n";
$OUT .= "        option domain-name \"vpnisl2\";\n";
$OUT .= "        option routers 192.168.102.2;\n";
$OUT .= "       option domain-name-servers 192.168.102.2;\n";
$OUT .= "        host lab {\n";
$OUT .= "        hardware ethernet 00:24:82:4C:5b:ce; fixed-address 192.168.102.4;}\n";
$OUT .= "}\n";

should work, not tested, let us know

Change the content of file 99group and I have this error:

Code: [Select]

{ and } are special characters within template fragments. You will need to use \{ and \} for them to work correctly.

[Stefano]

thank you Charlie..

I'm pretty confused as I'm scripting in vbscript, javascript, php..

[CharlieBrady]

Code: [Select]

group {
        option domain-name "vpnisl2";
        option routers 192.168.102.2;
        option domain-name-servers 192.168.102.2;
        host lab {
        hardware ethernet 00:24:82:4C:5b:ce; fixed-address 192.168.102.4;}
}


Change it to:

Code: [Select]

group \{
        option domain-name "vpnisl2";
        option routers 192.168.102.2;
        option domain-name-servers 192.168.102.2;
        host lab \{
        hardware ethernet 00:24:82:4C:5b:ce; fixed-address 192.168.102.4;\}
\}

The problem is that the perl interpreter is trying to interpret what it finds inside the {} blocks in your template, but what it finds there is not perl.

Change it to:

Code: [Select]

group \{
        option domain-name "vpnisl2";
        option routers 192.168.102.2;
        option domain-name-servers 192.168.102.2;
        host lab \{
        hardware ethernet 00:24:82:4C:5b:ce; fixed-address 192.168.102.4;\}
\}

It works great thanks a lot Charlie and Stef. I've learned something new.
