OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Just install the OpenSSH package directly in Preware, and follow the instructions in the HomePage link in the package description in Preware.
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Install OpenSSH
ipkg-opt install openssh
Note that the default configuration of OpenSSH does not enable SFTP. Since SCP just uses basic SSH, that works.
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Kill the OpenSSH daemon automatically started by ipkg
killall sshd
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Mount the file system as readwrite
If your root filesystem is still mounted readonly, you will not be able to write for example to /etc/conf.d, which we'll be doing in the next step.
mount -o remount,rw /
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Install an upstart event for the OpenSSH daemon
cd /etc/event.d/ wget http://gitorious.org/webos-internals/bootstrap/blobs/raw/master/etc/event.d/optware-openssh
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
[Optional step] Connecting to your pre over 3G (EVDO, UMTS) or WiFi
Generally, most seem to think that's a bad idea. Take a look at the script /etc/event.d/optware-openssh. Notice that it automatically modifies the firewalls rules to enable incoming SSH on port 222 over WiFi (interface eth0) connections only. Follow the directions in the script to enable SSH on all interfaces (including your 3G interface), if you wish.
Look at the script starting openssh:
cat /etc/event.d/optware-openssh
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Start the OpenSSH daemon for testing
initctl start optware-openssh
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Obtain the IP address of your Pre
Look for the "inet addr://Your.IP.Address//" to get the ip address for your WIFI connection:
ifconfig eth0
To get the ip address for your 3G (EVDO, UMTS) connection:
ifconfig ppp0
Alternatively, you can install the Preware application "What is my IP?" for a convenient GUI to lookup IPs on all your interfaces.
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Test your SSH installation
DO NOT CLOSE YOUR TELNET SESSION YET. DO THIS IN A NEW WINDOW From a remote system SSH to your Pre using //your// username and port 222. For example, from a Linux desktop you would run.
ssh -p 222 PRE-USERNAME@YOUR-PRE-IP-ADDR
From a Windows desktop we recommend using PuTTY.
Logout when done with "exit".
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Remount the file system as readonly
mount -o remount,ro /
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Reboot your device
reboot
Confirm that you can still access it after it boots using SSH.
OBSOLETE OBSOLETE OBSOLETE: This page is obsolete.
Optionally disable dev mode.
You may choose to disable dev mode at this point. There is no security issue to leaving dev mode on.
Return to the Next Steps page.
