Bounty's hard drive was replaced this morning due to I/O errors that started yesterday.
Nerds was in a bad state. Had to power cycle and fail-over worked as expected with a 90 second dept cluster NFS blip.
Ricola is down again for the third week in a row; this time a day early. We are performing a memory test before bringing it back in to service.
CIS will be performing maintenance on their DNS and DHCP services on February 10th between 6am and 7am. They anticipate a degradation of services during this window, which means you may experience issues:
- reaching Brown services, outside the department
- obtaining a DHCP address on the RLAB networks, wired and wireless
Authenticated Print Server
Tstaff has implemented an authenticated print server, printhost-dmz, that sits outside the department. A split DNS for printhost.cs.brown.edu is set up to point to correct print server depending on whether you are inside the department or outside.
More info about the Printing Service is located on the CS web ...
One of the departmental GPFS NFS gateways, runts, was misbehaving. We had to fail over the cluster nfs ip address to another nfs server. There was a brief 90 sec blip for those linux workstations connected to this cluster nfs server ip address. Runts will be rebooted and re-added to the dept cluster nfs server ...
Patches for a vulnerability, being referred to as GHOST, have been released. This vulnerability is a buffer overflow bug affecting the gethostbyname() and gethostbyname2() function calls in the glibc library, which means pretty much every service is affected. Since the vulnerability could allow a remote attacker to make an application call to either of these ...
We just rebooted one of our GPFS NFS gateways (runts). It was showing a high load, which was affecting NFS throughput. The reboot only affected NFS clients and should have been relatively painless, at most a momentary freeze of Linux workstations.
