How to access your account

Arachne System Logins

The two primary methods of accessing the Arachne System are via secure terminal login to a Unix shell or a secure file transfer login.

Remote shell (terminal) access: Users must use an SSH capable application to make a terminal login to their CalWeb Unix web account. There is no telnet access to the CalWeb Unix Web servers. You may connect via a Internet Service Provider (ISP) or the campus dial-up modem pool. The system internet hostname is:

arachne.berkeley.edu (169.229.131.109) and is also known as: recluse.berkeley.edu spider.berkeley.edu and tarantula.berkeley.edu
Remote Secure File Transfer: Users may connect using Secure File Transfer Protocol (SFTP) login from any campus network or internet connected host to transfer files. SSH2 Secure Shell copying (scp) is also supported.

Via an AirBears, campus dial-up or direct connection on a core campus data network subnet having IP addresses beginning with 128.32., 169.229. or 136.152.
- Use: workstation internet connection software and SSH2 capable client software.
Via a non-core campus network connection or other internet connection.
- Use: workstation internet connection software Virtual Private Network (VPN) client software and SSH2 capable client software.
Note: Use of VPN on low-speed dial-up connections can be very slow. For connections from off-campus IST recommends using a high-speed internet connection such as DSL or cable modem connection.

Effective 11 July 2007 at 3pm the following requirements must be met to access the Arachne System:

An active internet connection (campus or non-campus).
The internet connection must be using an IP address that has a internet Domain Name Service (DNS) PTR record so it can pass a reverse IP address verification test.
If connection does not have an IP address being with 128.32., 169.229. or 136.152 or does not have a DNS PTR record, VPN must be used to map originating IP address to a UC Berkeley campus network one with a DNS PTR record.
Using client software that is capable of using the SSH2 secure shell protocol for a secure terminal or file transfer (SFTP or scp) connection.
