Today started off with a bit of panic, as I hadn't set my alarm. Me being a west-coaster, 7:20 (when I woke up) is an entirely reasonable time to get up as far as my body is concerned. Only, I needed to get dressed and breakfasted before my first session at 8:30. Aie! I had to eat quick, but I got there. Didn't get a chance to check work email, though.
ATT326: Advanced Linux Troubleshooting
An ATT, therefore hard to summarize. But I learned about a few new commands I didn't know about before. Like strace. And vimdiff.
TUT130: Challenges in Storage I/O in Virtualization
Another nice one, but an emergency at work (printing down in a dorm, during finals week) distracted me heavily during the first half of it. Which resulted in the following note in my notes:
TUT216: OES2 SP1 Architectural Overview
There is a LOT of new stuff in SP1.
TUT211: Enhanced Protocol Support in OES2 SP1
This is the session where they went into detail about the AFP and CIFS support. They said that netatalk, the existing AFP stack on Linux, gets really slow once you go over the 20 concurrent users. Whoa! I can soooo understand why Novell felt the need to make a new one.
Tonight was the night formerly known as 'Sponsor Night,' but has a new name now that everyone who gets a booth is no longer a 'sponsor'. Some are sponsors, some are exhibiters. I can't keep track. Anyway, today was their party. "World of Novellcraft!" Homage to vid-gaming.
Lots of Wii, lots of Rock Band, some Halo, lots of women dressed in Renaissance Festival gear getting their pictures taken by the 90%+ male audience. I've blogged before about my ambivalence about Sponsor Night. I lasted until about 7, when I came back to the hotel.
Tomorrow I have an actual LUNCH BREAK in my schedule! Ooo! AndSoul Asylum Soul Coughing Collective Soul plays the concert! I've been listening to two of their CD's for the past two months so I think I may even know a few songs by now.

TUT130: Challenges in Storage I/O in Virtualization
Another nice one, but an emergency at work (printing down in a dorm, during finals week) distracted me heavily during the first half of it. Which resulted in the following note in my notes:
NPIV looks really nifty. Look into it.NPIV being how you can use fibre-channel zoning to zone off VM's, rather than HBA's. Highly useful. I also learned about a neat new thing called Virtual Fabrics. Virtual Fabrics work kind of like VLANS for fabrics. You can segregate your fabrics into fabrics that share hardware but nothing else. Handy if your, say, Solaris admins don't want you mucking about with their zoning, while saving money through consolidated hardware.
TUT216: OES2 SP1 Architectural Overview
There is a LOT of new stuff in SP1.
- It will include eDir 8.8.4 (8.8.3 will ship this summer sometime)
- NCP and eDir will be fully 64-bit
- OES2 SP1 will be based on SLES SP2, which will be releasing about the same time
- AFP Support
- AFP 3.1
- Uses Diffie-Helman 1 for password exchange, meaning the 8-character password problem is solved.
- Fully SMP-safe
- Has cross-protocol locking with NCP. CIFS doesn't have cross-protocol locking yet, but IIRC, Samba does
- Does not need LUM enabled users
- CIFS Support
- NTLMv1, but v2 is a possibility if enough people ask, so file those enhancement requests!!
- CIFS is separate from Samba, therefore can not be used in conjunction with Domain Services for Windows
- As with AFP, fully SMP safe
- EDir 8.8.4
- LDAP auditing enhanced
- "newer auth protocols", but they didn't say what.
TUT211: Enhanced Protocol Support in OES2 SP1
This is the session where they went into detail about the AFP and CIFS support. They said that netatalk, the existing AFP stack on Linux, gets really slow once you go over the 20 concurrent users. Whoa! I can soooo understand why Novell felt the need to make a new one.
- The 8 character password limit has been fixed! They now support DH1 for passing passwords.
- The 'afptcp' daemon can use one password protocol at a time, so you can only use DH1, or one of the other three I can't remember.
- Support for OSX 10.1 and 10.2 is scanty, and 10.5 is limited but users may not notice anyway.
- Passwords will be case sensitive.
- Kerberos will be in a future release
- Performance is faster than NetWare, partly due to the ability to multi-thread
- Can register services by way of SLP
- Only supports NSS for the time being, the other Linux file-systems will be a future feature.
- Can support 500 concurrent users, and 1000+ in the future. This fits our current AFP loads.
- We can configure more about how it works than we could on NetWare, such as how many worker threads to spawn.
- Has meaninful debug logs!
- Has a new command, 'afpstat' that works like 'netstat' for giving a snapshot of afp connections.
