Outgoing connections
====================
Connection restrictions
-----------------------
Outgoing connections, from Salomon Cluster login nodes to the outside world, are restricted to following ports:
|Port|Protocol|
|---|---|
|22|ssh|
|80|http|
|443|https|
|9418|git|
!!! Note "Note"
Please use **ssh port forwarding** and proxy servers to connect from Salomon to all other remote ports.
Outgoing connections, from Salomon Cluster compute nodes are restricted to the internal network. Direct connections form compute nodes to outside world are cut.
Port forwarding
---------------
### Port forwarding from login nodes
!!! Note "Note"
Port forwarding allows an application running on Salomon to connect to arbitrary remote host and port.
It works by tunneling the connection from Salomon back to users workstation and forwarding from the workstation to the remote host.
Pick some unused port on Salomon login node (for example 6000) and establish the port forwarding:
```bash
local $ ssh -R 6000:remote.host.com:1234 salomon.it4i.cz
```
In this example, we establish port forwarding between port 6000 on Salomon and port 1234 on the remote.host.com. By accessing localhost:6000 on Salomon, an application will see response of remote.host.com:1234. The traffic will run via users local workstation.
Port forwarding may be done **using PuTTY** as well. On the PuTTY Configuration screen, load your Salomon configuration first. Then go to Connection->SSH->Tunnels to set up the port forwarding. Click Remote radio button. Insert 6000 to Source port textbox. Insert remote.host.com:1234. Click Add button, then Open.
Port forwarding may be established directly to the remote host. However, this requires that user has ssh access to remote.host.com
```bash
$ ssh -L 6000:localhost:1234 remote.host.com
```
Note: Port number 6000 is chosen as an example only. Pick any free port.
### Port forwarding from compute nodes
Remote port forwarding from compute nodes allows applications running on the compute nodes to access hosts outside Salomon Cluster.
First, establish the remote port forwarding form the login node, as [described above](outgoing-connections/#port-forwarding-from-login-nodes).
Second, invoke port forwarding from the compute node to the login node. Insert following line into your jobscript or interactive shell
```bash
$ ssh -TN -f -L 6000:localhost:6000 login1
```
In this example, we assume that port forwarding from login1:6000 to remote.host.com:1234 has been established beforehand. By accessing localhost:6000, an application running on a compute node will see response of remote.host.com:1234
### Using proxy servers
Port forwarding is static, each single port is mapped to a particular port on remote host. Connection to other remote host, requires new forward.
!!! Note "Note"
Applications with inbuilt proxy support, experience unlimited access to remote hosts, via single proxy server.
To establish local proxy server on your workstation, install and run SOCKS proxy server software. On Linux, sshd demon provides the functionality. To establish SOCKS proxy server listening on port 1080 run:
```bash
local $ ssh -D 1080 localhost
```
On Windows, install and run the free, open source [Sock Puppet](http://sockspuppet.com/) server.
Once the proxy server is running, establish ssh port forwarding from Salomon to the proxy server, port 1080, exactly as [described above](outgoing-connections/#port-forwarding-from-login-nodes).
```bash
local $ ssh -R 6000:localhost:1080 salomon.it4i.cz
```
Now, configure the applications proxy settings to **localhost:6000**. Use port forwarding to access the [proxy server from compute nodes](outgoing-connections/#port-forwarding-from-compute-nodes) as well .

------------
Do not use shared filesystems at IT4Innovations as a backup for large amount of data or long-term archiving purposes.
!!! Note "Note"
../../img/The IT4Innovations does not provide storage capacity for data archiving. Academic staff and students of research institutions in the Czech Republic can use [CESNET Storage service](https://du.cesnet.cz/).
The CESNET Storage service can be used for research purposes, mainly by academic staff and students of research institutions in the Czech Republic.
User of data storage CESNET (DU) association can become organizations or an individual person who is either in the current employment relationship (employees) or the current study relationship (students) to a legal entity (organization) that meets the “Principles for access to CESNET Large infrastructure (Access Policy)”.
User may only use data storage CESNET for data transfer and storage which are associated with activities in science, research, development, the spread of education, culture and prosperity. In detail see “Acceptable Use Policy CESNET Large Infrastructure (Acceptable Use Policy, AUP)”.

CESNET storage access
---------------------
### Understanding Cesnet storage
!!! Note "Note"
It is very important to understand the Cesnet storage before uploading data. Please read <https://du.cesnet.cz/en/navody/home-migrace-plzen/start> first.
Once registered for CESNET Storage, you may [access the storage](https://du.cesnet.cz/en/navody/faq/start) in number of ways. We recommend the SSHFS and RSYNC methods.
### SSHFS Access
!!! Note "Note"
SSHFS: The storage will be mounted like a local hard drive
The SSHFS provides a very convenient way to access the CESNET Storage. The storage will be mounted onto a local directory, exposing the vast CESNET Storage as if it was a local removable harddrive. Files can be than copied in and out in a usual fashion.
First, create the mountpoint
```bash
$ mkdir cesnet
```
Mount the storage. Note that you can choose among the ssh.du1.cesnet.cz (Plzen), ssh.du2.cesnet.cz (Jihlava), ssh.du3.cesnet.cz (Brno) Mount tier1_home **(only 5120M !)**:
```bash
$ sshfs username@ssh.du1.cesnet.cz:. cesnet/
```
For easy future access from Anselm, install your public key
```bash
$ cp .ssh/id_rsa.pub cesnet/.ssh/authorized_keys
```
Mount tier1_cache_tape for the Storage VO:
```bash
$ sshfs username@ssh.du1.cesnet.cz:/cache_tape/VO_storage/home/username cesnet/
```
View the archive, copy the files and directories in and out
```bash
$ ls cesnet/
$ cp -a mydir cesnet/.
$ cp cesnet/myfile .
```
Once done, please remember to unmount the storage
```bash
$ fusermount -u cesnet
```
### Rsync access
!!! Note "Note"
Rsync provides delta transfer for best performance, can resume interrupted transfers
Rsync is a fast and extraordinarily versatile file copying tool. It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. Rsync is widely used for backups and mirroring and as an improved copy command for everyday use.
Rsync finds files that need to be transferred using a "quick check" algorithm (by default) that looks for files that have changed in size or in last-modified time. Any changes in the other preserved attributes (as requested by options) are made on the destination file directly when the quick check indicates that the file's data does not need to be updated.
More about Rsync at <https://du.cesnet.cz/en/navody/rsync/start#pro_bezne_uzivatele>
Transfer large files to/from Cesnet storage, assuming membership in the Storage VO
```bash
$ rsync --progress datafile username@ssh.du1.cesnet.cz:VO_storage-cache_tape/.
$ rsync --progress username@ssh.du1.cesnet.cz:VO_storage-cache_tape/datafile .
```
Transfer large directories to/from Cesnet storage, assuming membership in the Storage VO
```bash
$ rsync --progress -av datafolder username@ssh.du1.cesnet.cz:VO_storage-cache_tape/.
$ rsync --progress -av username@ssh.du1.cesnet.cz:VO_storage-cache_tape/datafolder .
```
Transfer rates of about 28MB/s can be expected.

CESNET storage access
---------------------
### Understanding Cesnet storage
!!! Note "Note"
It is very important to understand the Cesnet storage before uploading data. Please read <https://du.cesnet.cz/en/navody/home-migrace-plzen/start> first.
Once registered for CESNET Storage, you may [access the storage](https://du.cesnet.cz/en/navody/faq/start) in number of ways. We recommend the SSHFS and RSYNC methods.
### SSHFS Access
!!! Note "Note"
SSHFS: The storage will be mounted like a local hard drive
The SSHFS provides a very convenient way to access the CESNET Storage. The storage will be mounted onto a local directory, exposing the vast CESNET Storage as if it was a local removable harddrive. Files can be than copied in and out in a usual fashion.
First, create the mountpoint
```bash
$ mkdir cesnet
```
Mount the storage. Note that you can choose among the ssh.du1.cesnet.cz (Plzen), ssh.du2.cesnet.cz (Jihlava), ssh.du3.cesnet.cz (Brno) Mount tier1_home **(only 5120M !)**:
```bash
$ sshfs username@ssh.du1.cesnet.cz:. cesnet/
```
For easy future access from Anselm, install your public key
```bash
$ cp .ssh/id_rsa.pub cesnet/.ssh/authorized_keys
```
Mount tier1_cache_tape for the Storage VO:
```bash
$ sshfs username@ssh.du1.cesnet.cz:/cache_tape/VO_storage/home/username cesnet/
```
View the archive, copy the files and directories in and out
```bash
$ ls cesnet/
$ cp -a mydir cesnet/.
$ cp cesnet/myfile .
```
Once done, please remember to unmount the storage
```bash
$ fusermount -u cesnet
```
### Rsync access
!!! Note "Note"
Rsync provides delta transfer for best performance, can resume interrupted transfers
Rsync is a fast and extraordinarily versatile file copying tool. It is famous for its delta-transfer algorithm, which reduces the amount of data sent over the network by sending only the differences between the source files and the existing files in the destination. Rsync is widely used for backups and mirroring and as an improved copy command for everyday use.
Rsync finds files that need to be transferred using a "quick check" algorithm (by default) that looks for files that have changed in size or in last-modified time. Any changes in the other preserved attributes (as requested by options) are made on the destination file directly when the quick check indicates that the file's data does not need to be updated.
More about Rsync at <https://du.cesnet.cz/en/navody/rsync/start#pro_bezne_uzivatele>
Transfer large files to/from Cesnet storage, assuming membership in the Storage VO
```bash
$ rsync --progress datafile username@ssh.du1.cesnet.cz:VO_storage-cache_tape/.
$ rsync --progress username@ssh.du1.cesnet.cz:VO_storage-cache_tape/datafile .
```
Transfer large directories to/from Cesnet storage, assuming membership in the Storage VO
```bash
$ rsync --progress -av datafolder username@ssh.du1.cesnet.cz:VO_storage-cache_tape/.
$ rsync --progress -av username@ssh.du1.cesnet.cz:VO_storage-cache_tape/datafolder .
```
Transfer rates of about 28MB/s can be expected.
