Department Mailing List Server Maintenance, Aug 20, 6-8pm

August 20, 2008 by Rob McNicholas

The EECS Department’s mailing list server lists.eecs.berkeley.edu will be undergoing maintenance from 6pm-8pm on Wednesday, August 20th. During this time, mail sent to any departmental mailing list will be held for delivery until the maintenance is completed.

During this maintenance we will be upgrading the mailing list manager software to the latest version and migrating the service to a new, faster hardware.

Please send any questions to help@eecs.

Coeus/Project Downtime

August 20, 2008 by IRIS Staff

Attention System Administrators,

On Wednesday, August 20th from 6am-8am, IDSG will be migrating production file service of home directories and project space to the new NetApp filers. There will be downtime during this migration that will impact the majority of users in the department. Please evaluate the impact for your users and notify them of those details. A much shorter public announcement will be going out soon to the entire EECS community indicating that local System Administrators will be letting them know of any specific information as to how it will impact their work.

The following services will be affected:

– coeus
– project
– sww (not winsww)
– argus
– www.eecs and www.cs web servers
– the IRIS website

The following changes apply:

1. COEUS

– coeus.EECS.Berkeley.EDU will be replaced by home.EECS.Berkeley.EDU.

– NFS access will change from coeus:/vol/vol0/eecs/username to home:/eecs/username

– The amd and automaps will be appropriately changed.

– CIFS access will change from \\\\\\COEUS\HOME\username to
\\\\\\HOME\username

– The old hostname coeus will be a CNAME to home.EECS.Berkeley.EDU until September 20th.

2. PROJECT

– NFS access will change from project:/vol/vol[02]/projspace to project:/proj/projspace

**NOTE**: A few mount points will change in a different way. See the end of this announcement for details.

**NOTE2**: If your project spaces are merged, the details will be worked out with you directly outside of this announcement.

– The amd and automaps will be appropriately changed.

– CIFS share names will not be affected.

This announcement may be followed by additional updates if additional technical details need to be publicized. Certain requests may be delayed beyond the normal response time (e.g. amd/automap change requests, new user creation, project space creation, etc.) during the 2 weeks prior to the migration.

The downtimes for different services will be different. There will be one or more additional announcements as services get restored to allow early access to the appropriate systems. E.g. the actual downtime for coeus/home is expected to be only a few minutes.

This list will receive notice when access is restored.

Sysadmins should be ready to reboot systems that need to remount filesystems between 7:30 and 8 AM. CIFS access should resume during that time as well. The CIFS share names will not change and therefore should not require a reboot for those systems.

Be advised that there are a number of follow-up tasks after the outage, which could result in slow response from these systems.

If you experience problems during or after the outage, or have
additional questions – please contact Helpdesk at help@eecs or 2-7777 or 395 Cory.

New Unix General Login Server

August 7, 2008 by IRIS Staff

We’re pleased to announce login.EECS.Berkeley.EDU, the new Unix general login server running Solaris 10 x86_64.

This server is using [OpenSSH](http://openssh.org) as the SSH daemon, so if you haven’t already [converted your ssh.com ssh keys to OpenSSH keys](https://iris.eecs.berkeley.edu/15-faq/15-software/putty.html#import_key) you’ll need to do so before they’ll work on the new server.

Since login.eecs uses the x86_64 architecture, any binaries that you run from your home directory that were compiled on Sparc will need to be recompiled to work.

This server mounts the Solaris 10 for x86 sww. You should add
/usr/sfw/bin to your path (if you haven’t already) as most open-source software is available on Solaris 10 and therefore will not be on the Solaris 10 sww.

login.eecs will not mount /var/mail from mailspool.CS.Berkeley.EDU as this service will be discontinued in the near future. There will be an
announcement about that soon.

The old Unix General Login Server, argus.EECS.Berkeley.EDU will be phased
out at a later date. There will be an announcement about that soon as well.

BWRC core switch back on service

July 23, 2008 by Janet Shu

Around 1:50pm this afternoon, BWRC core router can not pass the network traffic as the CPU load hit nearly 98%. However, the networks within BWRC remained functional.

SSH attack triggered the spin cycle during that time. This BWRC switch was back on services at 3:00pm.

iPhone 2.0 and WEP on EECS 802.11b Wireless

July 23, 2008 by IRIS Staff

iPhones with the new 2.0 firmware, including the new iPhone 3g, may have problems getting onto the EECS 802.11b wireless network despite having the proper WEP key entered. Users of iPhones may see an error message about an incorrect password.

The workaround for this is to enter the WEP key in hexadecimal instead of ASCII without any preceding “0x” or “$” characters in front of the key.

While some wireless clients ask that hex keys be preceded by “0x” or “$”, the iPhone does not do this and will not properly join the EECS wireless network if these preceding characters are used.

For example, if the EECS 802.11b WEP key in ASCII were “IloveAppleInc”, the hex version of the key would be “496C6F76654170706C65496E63”. (This is not the actual EECS 802.11b WEP key – it is just an example) .

Enter “496C6F76654170706C65496E63” instead of “IloveAppleInc”. Do not use “0x496C6F76654170706C65496E63” or “$496C6F76654170706C65496E63”.

If you need assistance getting your iPhone onto the EECS wireless network, please contact the EECS Helpdesk in 395 Cory Hall, x2-7777.

Router Failure

July 22, 2008 by IRIS Staff

Just before 4 PM today, a core router management module failed. The unit did try to fail over to the backup but it was not a complete cut over and some services were disrupted. We attempted to reboot the module but that caused a more massive failure in the chassis for less than 1 min. The bad module has been removed and service has been restored. We are continuing to troubleshoot the first problem with the vendor.

IRIS Website and Mailing Lists Offline Due to Maintenance

July 21, 2008 by IRIS Staff

The IRIS website and Sympa mailing lists will be offline beginning at 10:00 p.m. on Wednesday, July 23, 2008 to allow me to perform some routine maintenance on their hosting server.

Total downtime should be brief and any messages sent to a Sympa mailing list will be queued and delivered after maintenance has been completed.
