Siac Usage

siac is the command line interface to Sia, for use by power users and those on headless servers. It comes as a part of the command line package, and can be run as ./siac from the same folder, or just by calling siac if you move the binary into your path.

Most of the following commands have online help. For example, executing siac wallet send help will list the arguments for that command, while siac host help will list the commands that can be called pertaining to hosting. siac help will list all of the top level command groups that can be used.

You can change the address of where siad is pointing using the -a flag. For example, siac -a :9000 status will display the status of the siad instance launched on the local machine with siad -a :9000.

Full Descriptions

Wallet tasks

• siac wallet init [-p] encrypts and initializes the wallet. If the -p flag is provided, an encryption password is requested from the user. Otherwise the initial seed is used as the encryption password. The wallet must be initialized and unlocked before any actions can be performed on the wallet.

Examples:

user@hostname:~$ siac -a :9920 wallet init
Seed is:
 cider sailor incur sober feast unhappy mundane sadness hinder aglow imitate amaze duties arrow gigantic uttered inflamed girth myriad jittery hexagon nail lush reef sushi pastry southern inkling acquire

Wallet encrypted with password: cider sailor incur sober feast unhappy mundane sadness hinder aglow imitate amaze duties arrow gigantic uttered inflamed girth myriad jittery hexagon nail lush reef sushi pastry southern inkling acquire

user@hostname:~$ siac -a :9920 wallet init -p
Wallet password:
Seed is:

Wallet encrypted with given password

• siac wallet unlock prompts the user for the encryption password to the wallet, supplied by the init command. The wallet must be initialized and unlocked before any actions can take place.

• siac wallet balance prints information about your wallet.

Example:

user@hostname:~$ siac wallet balance
Wallet status:
Encrypted, Unlocked
Confirmed Balance:   61516458.00 SC
Unconfirmed Balance: 64516461.00 SC
Exact:               61516457999999999999999999999999 H

• siac wallet address returns a never seen before address for sending siacoins to.

• siac wallet send [amount] [dest] Sends amount siacoins to dest. amount is in the form XXXXUU where an X is a number and U is a unit, for example MS, S, mS, ps, etc. If no unit is given hastings is assumed. dest must be a valid siacoin address.

• siac wallet lock locks a wallet. After calling, the wallet must be unlocked using the encryption password in order to use it further

• siac wallet seeds returns the list of secret seeds in use by the wallet. These can be used to regenerate the wallet

• siac wallet addseed prompts the user for his encryption password, as well as a new secret seed. The wallet will then incorporate this seed into itself. This can be used for wallet recovery and merging.

Host tasks

• host config [setting] [value]

is used to configure hosting.

In version 1.4.3.0, sia hosting is configured as follows:

Setting	Value
acceptingcontracts	Yes or No
collateral	in SC / TB / Month, 10-1000
collateralbudget	in SC
ephemeralaccountexpiry	in seconds
maxcollateral	in SC, max per contract
maxduration	in weeks, at least 12
maxephemeralaccountbalance	in SC
maxephemeralaccountrisk	in SC
mincontractprice	minimum price in SC per contract
mindownloadbandwidthprice	in SC / TB
minstorageprice	in SC / TB
minuploadbandwidthprice	in SC / TB

You can call this many times to configure you host before announcing. Alternatively, you can manually adjust these parameters inside the host/config.json file.

• siac host announce makes an host announcement. You may optionally supply a specific address to be announced; this allows you to announce a domain name. Announcing a second time after changing settings is not necessary, as the announcement only contains enough information to reach your host.

• siac host -v outputs some of your hosting settings.

Example:

user@hostname:~$ siac host -v
Host settings:
Storage:      2.0000 TB (1.524 GB used)
Price:        0.000 SC per GB per month
Collateral:   0
Max Filesize: 10000000000
Max Duration: 8640
Contracts:    32

• siac hostdb -v prints a list of all the know active hosts on the network.

Renter tasks

• siac renter upload [filename] [nickname] uploads a file to the sia network. filename is the path to the file you want to upload, and nickname is what you will use to refer to that file in the network. For example, it is common to have the nickname be the same as the filename.

• siac renter ls displays a list of the your uploaded files currently on the sia network by nickname, and their filesizes.

• siac renter download [nickname] [destination] downloads a file from the sia network onto your computer. nickname is the name used to refer to your file in the sia network, and destination is the path to where the file will be. If a file already exists there, it will be overwritten.

• siac renter rename [nickname] [newname] changes the nickname of a file.

• siac renter delete [nickname] removes a file from your list of stored files. This does not remove it from the network, but only from your saved list.

• siac renter queue shows the download queue. This is only relevant if you have multiple downloads happening simultaneously.

• siac renter setallowance sets the amount of money that can be spent over a given period. If no flags are set you will be walked through the interactive allowance setting. To update only certain fields, pass in those values with the corresponding field flag, for example '--amount 500SC'.

• siac renter allowance views the current allowance, which controls how much money is spent on file contracts.

Skynet tasks

• siac skynet upload [source filepath] [destination siapath] uploads a file or directory to Skynet. A skylink will be produced for each file. The link can be shared and used to retrieve the file. The file(s) that get uploaded will be pinned to this Sia node, meaning that this node will pay for storage and repairs until the file(s) are manually deleted.

• siac skynet ls lists all skyfiles that the user has pinned along with the corresponding skylinks. By default, only files in var/skynet/ will be displayed.

• siac skynet download [skylink] [destination] downloads a file from Skynet using a skylink.

• siac skynet pin [skylink] [destination siapath] pins the file associated with this skylink by re-uploading an exact copy. This ensures that the file will still be available on skynet as long as you continue maintaining the file in your renter.

• siac skynet unpin [siapath] unpins a skyfile, deleting it from your list of stored files.

• siac skynet convert [source siaPath] [destination siaPath] converts a siafile to a skyfile and then generates its skylink. A new skylink will be created in the user's skyfile directory. The skyfile and the original siafile are both necessary to pin the file and keep the skylink active. The skyfile will consume an additional 40 MiB of storage.

• siac skynet blacklist [skylink] will add or remove a skylink from the Renter's Skynet Blacklist

Gateway tasks

• siac gateway prints info about the gateway, including its address and how many peers it's connected to.

• siac gateway list prints a list of all currently connected peers.

• siac gateway connect [address:port] manually connects to a peer and adds it to the gateway's node list.

• siac gateway disconnect [address:port] manually disconnects from a peer, but leaves it in the gateway's node list.

Miner tasks

• siac miner status returns information about the miner. It is only valid for when siad is running.

• siac miner start starts running the CPU miner on one thread. This is virtually useless outside of debugging.

• siac miner stop halts the CPU miner.

General commands

• siac consensus prints the current block ID, current block height, and current target.

• siac stop sends the stop signal to siad to safely terminate. This has the same affect as C^c on the terminal.

• siac version displays the version string of siac.

• siac update checks the server for updates.
