Just add a `debug` option containing the value true to the `input` section. The log files will be created depending on the parent directory of the logfile option. + +The following example will log an active ssh/telnet session `/home/oxidized/.config/oxidized/log/<IP-Address>-<PROTOCOL>`. The file will be truncated on each consecutive ssh/telnet session, so you need to put a `tailf` or `tail -f` on that file! + +```yaml +log: /home/oxidized/.config/oxidized/log + +... + +input: + default: ssh, telnet + debug: true + ssh: + secure: false +``` + +## Privileged mode + +To start privileged mode before pulling the configuration, Oxidized needs to send the enable command. You can globally enable this, by adding the following snippet to the global section of the configuration file. + +```yaml +vars: + enable: S3cre7 +``` + +## Removing secrets + +To strip out secrets from configurations before storing them, Oxidized needs the `remove_secret` flag. You can globally enable this by adding the following snippet to the global section of the configuration file. + +```yaml +vars: + remove_secret: true +``` + +Device models that contain substitution filters to remove sensitive data will now be run on any fetched configuration. + +As a partial example from ios.rb: + +```ruby + cmd :secret do |cfg| + cfg.gsub! /^(snmp-server community).*/, '\\1 <configuration removed>' + (...) + cfg + end +``` + +The above strips out snmp community strings from your saved configs. + +**NOTE:** Removing secrets reduces the usefulness as a full configuration backup, but it may make sharing configs easier. + +## Disabling SSH exec channels + +Oxidized uses exec channels to make information extraction simpler, but there are some situations where this doesn't work well, e.g. configuring devices. This feature can be turned off by setting the `ssh_no_exec` +variable. + +```yaml +vars: + ssh_no_exec: true +``` + +## SSH Auth Methods + +By default, Oxidized registers the following auth methods: `none`, `publickey` and `password`. However you can configure this globally, by groups, models or nodes. + +``` +vars: + auth_methods: none, publickey, password, keyboard-interactive +``` + +## SSH Proxy Command + +Oxidized can `ssh` through a proxy as well. To do so we just need to set `ssh_proxy` variable with the proxy host information. + +This can be provided on a per-node basis by mapping the proper fields from your source. + +An example for a `csv` input source that maps the 4th field as the `ssh_proxy` value. + +```yaml +... +map: + name: 0 + model: 1 +vars_map: + enable: 2 + ssh_proxy: 3 +... +``` + +## FTP Passive Mode + +Oxidized uses ftp passive mode by default. Some devices require passive mode to be disabled. To do so, we can set `input.ftp.passive` to false - this will make use of FTP active mode. + +```yaml +input: + ftp: + passive: false +``` + +## Advanced Configuration + +Below is an advanced example configuration. You will be able to (optionally) override options per device. The router.db format used is `hostname:model:username:password:enable_password`. Hostname and model will be the only required options, all others override the global configuration sections. + +```yaml +--- +username: oxidized +password: S3cr3tx +model: junos +interval: 3600 #interval in seconds +log: ~/.config/oxidized/log +debug: false +threads: 30 +timeout: 20 +retries: 3 +prompt: !ruby/regexp /^([\w.@-]+[#>]\s?)$/ +vars: + enable: S3cr3tx +groups: {} +rest: 127.0.0.1:8888 +pid: ~/.config/oxidized/oxidized.pid +input: + default: ssh, telnet + debug: false + ssh: + secure: false +output: + default: git + git: + user: Oxidized + email: oxidized@example.com + repo: "~/.config/oxidized/oxidized.git" +source: + default: csv + csv: + file: ~/.config/oxidized/router.db + delimiter: !ruby/regexp /:/ + map: + name: 0 + model: 1 + username: 2 + password: 3 + vars_map: + enable: 4 +model_map: + cisco: ios + juniper: junos +``` + +## Advanced Group Configuration + +For group specific credentials + +```yaml +groups: + mikrotik: + username: admin + password: blank + ubiquiti: + username: ubnt + password: ubnt +``` + +and add group mapping + +```yaml +map: + model: 0 + name: 1 + group: 2 +``` + +For model specific credentials + +```yaml +models: + junos: + username: admin + password: password + ironware: + username: admin + password: password + vars: + enable: enablepassword + apc_aos: + username: apc + password: password +``` + +## RESTful API and Web Interface + +The RESTful API and Web Interface is enabled by configuring the `rest:` parameter in the config file. This parameter can optionally contain a relative URI. + +```yaml +# Listen on http://127.0.0.1:8888/ +rest: 127.0.0.1:8888 +``` + +```yaml +# Listen on http://10.0.0.1:8000/oxidized/ +rest: 10.0.0.1:8000/oxidized +``` + +## Triggered backups + +A node can be moved to head-of-queue via the REST API `GET/POST /node/next/[NODE]`. This can be useful to immediately schedule a fetch of the configuration after some other event such as a syslog message indicating a configuration update on the device. + +In the default configuration this node will be processed when the next job worker becomes available, it could take some time if existing backups are in progress. To execute moved jobs immediately a new job can be added automatically: + +```yaml +next_adds_job: true +``` + +This will allow for a more timely fetch of the device configuration. |
