This solution is strange because - you may hit issues because not all FS locking commands will be supported - running multiple database instances connecting to the same DB files is normally done in an Oracle RAC configuration. You don't run Oracle on the app servers you run it on database servers and use a shared filesystem like ASM or OCFS2 normally connected to the DB files over a SAN. Network filesystems are not normally used for database files. I am sure you are correct, I don't have any experience with Oracle or large, distributed DB installations. Is there a good reason you need more than one oracle instance? No! I think I phrase the question incorrectly to start with.

I have setup an Internet Cafe for a mate of mine in a far away land. In what seems like a nightmare I haven't woken up from yet, he is proposing a crazy marketing stunt to pull in people to the Cafe. A $1000 reward for obtaining the root password off one of the PC terminals! I don't even want to repeat that, I'm just trying to think of it as the ultimate vote of confidence ;-) Outline of the system design is: * The PCs are all running Ubuntu Breezy (as is the server). * The local user accounts are supplied via NIS from a central server (only user accts, all passwords disabled) as all authentication is done via PAM radius, back to the central server. Yes, I know LDAP will be in v2. * IPsec secures communication between each PC and the server * There is an admin account with full root sudo access on each PC and the root password has been set the same (doesn't seem like a lot of point if admin has root sudo access anyway to have it different - correct me if I'm off track here) * The PC admin/root passwords do not match those on the server Rules of engagement * Must be on-site and present (no at/cron jobs) * Cannot boot off anything else (of course) * Cannot change boot parameters * No malicious activity (I know, what does this mean under these circumstances?!) * They have to open a file only readable by root and report back the contents plus the root password plus the method of attack * I am going to push for this to only be for 1-2 weeks tops I'd love some feedback from people on what further preps I should undertake. I know that sounds very open ended but should I really trust the default installation to be safe enough? Of course, a public system like this is always open to naughtiness but legitimising it is really scary. -- Simon Wong [EMAIL PROTECTED] -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Alternatively, login and run the commands interactively (but given you're running commands directly from ssh, I'm assuming this is actually a script?). yep, trying to script it :-) If you go with the sudo group idea, you may want to setup a special user (updater or something) that can only run specific commands like apt-get with sudo and even then, restrict the options that can be passed as well. Good idea, that sounds like the way to go but I expect that means setting up an SSH key with the specific command so that the updater user can login via SSH and do only that one thing.

[SLUG] Login with radius authentication
Here's on for the RADIUS gurus... I'm trying to piggy back off a radius authentication setup that I have for wireless access and use that for logging into some Ubuntu PC's. Now, I have the authentication working so that password is checked and accepted or rejected from the radius server via PAM on the central server...yay! Now, I want a home directory automatically created for the user so they can actually login through gdm. This fails because there's no group information for the user and I guess no default shell either. Combing the web is still not getting me a long way.

The results after that are the real results where buffering no longer gives an advantage and you see the true sustained (lack of) throughput. OK. That would indicate that you're filling the bus to the hard disk, not the network between the CPUs. yeah, the network throughput (iptraf) was only about 20Mbits, well below what I was expecting for a Gigabit to 100Mbit connection. dd is writing a lot of empty blocks down to that disk. You might want to consider using tar is the filesystem has a lot of empty space. True, I should have elaborated that this was an NTFS partition image. That's a very handwaving question since you haven't told us anything about the computer. The bottleneck obviously varies with the hardware. Sorry, that's the sort of question you get from someone when they're stuck :-) Now set the machine for maximum performance. hdparm should report 32b UDMA, write caching, look ahead, APM disabled, fast AAM goodness. TCP buffers should BINGO! Thank-you, thank-you, thank-you! I didn't think about DMA :-( I assumed that Knoppix would turn on such things for me! (1) Turning on DMA (hdparm -d1 /dev/hda): On the client: # time ssh [EMAIL PROTECTED] cat client.img.gz | gunzip /dev/hda1 time reports a real time of 6 mins 1.8s (including ssh password entry)! There's still a slow down at the 1GB mark for about 12 seconds, then full speed transfer is reached for another 200MB or so, after that the transfer trickles along until the end of the file. So, if I get the partition image size as close to or below that 1GB mark things are as fast as they're gonna get. (2) Tuning with hdparm So this time I tried: # hdparm -d1 -c1 /dev/hda time reported basically the same time within a few seconds. Performance was the same. (3) Netcat I thought I would try netcat. Server: $ cat image.img.gz | nc -l -p 5030 -q 10 Client: # time nc serverip 5030 | gunzip /dev/hda1 time reports real time of 5m18s. Wow! Buffers filled at around 1200MB, another burst at around 1400MB but then crawling (270kbits/sec) to the end. Test. Are you CPU-bound, I/O-bound or network bound (top, vmstat, etc)? If you are, is that bound reasonable (eg, 90% of the sustained disk write rate)? So, in the end definately disk I/O bound. You might want to try transferring from and to /dev/null to check network+CPU preformance. Note that ssh has a special Alrighty then, netcat to /dev/null. time gives real 2m50s. performance issue -- it uses a 128MB window so the bandwidth- delay product needs to be under that for ssh to run at maximum speed. Not sure where to tune that. I'll put that aside for now. Now you're found the bottleneck, fix it. Repeat test until one of the hard bounds is reached. If possible, chose a better method to move away from that bound (eg, dd v tar; ssh v ftp of of a gpg-encrypted file). hence netcat instead of ssh. Since, this is now happening within a reasonable length of time here's some more results: 1. Netcat + dd nc serverip 5030 | gunzip | dd of=/dev/hda1 time gives real 5m52s. So quite a bit slower than the redirect. Remember to record your results at each step. Let us know the interesting numbers (eg, what is the real throughput of your particular drive). There's surprisingly few real benchmarks out there, so you'll be helping a lot by posting your numbers. Well, thanks so much for your help Glen. I really appreciate your teach a man to fish support :-) I hope the above results are of use to anyone else needing to do the same sort of thing. I think I'll try and get that partition image size down (bye bye system restore). Of course, for linux clients this is so much easier (no activation issues) so setting up the preseed file for Ubuntu is my next step.
