Commands ¶

Nearly all commands have the following common options:

-cfg ¶

Path to configuration file. May be overridden by $NNCPCFG environment variable. If file file is an encrypted eblob, then ask for passphrase to decrypt it first.

-debug

Print debug messages. Normally this option should not be used.

-minsize

Minimal required resulting packet size, in KiBs. For example if you send 2 KiB file and set -minsize 4, then resulting packet will be 4 KiB (containing file itself and some junk).

-nice

Set desired outgoing packet niceness level.

-replynice

Set desired reply packet niceness level. Only freq and exec packets look at that niceness level.

-via

Override via configuration option for destination node. Specified nodes must be separated with comma: NODE1,NODE2. With -via - you can disable relaying at all.

-spool

Override path to spool directory. May be specified by $NNCPSPOOL environment variable.

-log

Override path to logfile. May be specified by $NNCPLOG environment variable.

-quiet

Print only errors, omit simple informational messages. In any case those messages are logged, so you can reread them using nncp-log command.

-progress, -noprogress

Either force progress showing, or disable it.

-version

Print version information.

-warranty

Print warranty information (no warranty).

All commands respect $TMPDIR environment variable.

If you set $NNCPNOSYNC=1, then all fsync operations will be skipped. That is dangerous option, but if there there are abilities to rollback possibly corrupted state to some stable snapshot, then disabled fsync can give considerable increase in performance.
