As an only-occasional visitor to the So'ton meetings I certainly find that there are usually more new (or forgotten ;-) faces than familiar/remembered ones, and I remember the first few visits feeling a little bit out of it .

[Hampshire] trouble after memory upgrade
Hello, this is an Acer Aspire T180 desktop: Linux ss07 2.6.24-19-generic #1 SMP Wed Aug 20 17:53:40 UTC 2008 x86_64 GNU/Linux Came with 2*512MB ROM, with 4 slots. Bought in November 2006. I have just got 2*1GB sticks from Crucial, and moved the current 1GB from banks 1,2 to banks 3,4 (it was recommended in the little note that came with the memory that smaller-capacity units should occupy the higher slots), putting the new 2GB in slots 1 and 2. At boot up attempts we always get to the GRUB prompt, then: A. 1. Select the current kernel, gets as far as 'Starting up...' then freezes. 2. Select the current kernel, see some panic trace for a moment then reboots. 3. Select the current kernel, see 'Kernel alive and the next line then reboots. 4. Select the current kernel, see 'Loading, please wait...' then freezes. 5. as 4, but with a scrambled screen of 4 'loading' messages dotted around it. B. On to memtest86. 1. crash after 22sec on test2 with a Stack Fault. 2. reboots after 15 sec. 3. stack fault after 3 sec. 4. reboot after 15 sec. 5. stack fault after 53 sec. C. Remove the 2*512 MB sticks leaving just the 2*1GB new memory. 1. Boots into Ubuntu 8.04 fine. D. Put the 2*512MB back in, 1,2. 2 memtest hangs 3,4. 2 memtest reboots. 5. Recovery mode Ubuntu immediately reboots. E. Swap round the two 512MB sticks, having brushed the slots and cleaned the memory contacts with an eraser. 1.Ubuntu start hangs at 'Kernel remapping...' 2. memtest runs ok for 2 minutes (!) 3. memtest reboots after 3 sec 4. memtest stackfaults after 1'45''. The old memory was behaving OK (at least, not breaking) before I opened the box. I am now running with just the 2GB new memory, and apparently things are behaving. I was wondering, since a) the high memory banks 3 and 4 were previously unused before I moved the old memory into them, b) the machine is almost a couple of years old, c) it is in a not-optimal environment (had a bit of dust inside) d) the misbehaviour seems a bit erratic during and between trial runs above, this makes me suspect that I have not-good contact between the 2 512MB sticks and the slots on the motherboard.

Actually, just checked and the new mem is PC2-4200 and the old sticks are labelled PC2-4300 which in fact both denote 533MHz (thank you wikipaedia(1) ) - so they "should" be OK together... I will have a go with memtesting the old ones in isolation tonight and check that memtest agrees with me. If the sets are confirmed to both be 533MHz perhaps I will try putting the old ones back into the first pair of slots where they were originally. (1) http://en.wikipedia.org/wiki/DDR2_SDRAM - which also confirms Vic's suspicion: Faster DDR2 DIMMs are compatible with slower DDR2 DIMMs; however, the faster module runs at the slower module's speed. Using slower DDR2 memory in a system capable of higher speeds results in the bus running at the speed of the slowest memory in use. And I must say that just running with 2GB instead of 1 makes a big difference already. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

The new & old sticks have the same connector & keyslot layout (obviously...) ; they have some visual differences of course (different manufr-branding, and wd have to open the case again to tell you more); the new sticks were identified by the Crucial web site tool when I gave that tool my system's make & model, which I understand to be quite a reputable tool. They are identified on their invoice as '2GB kit (1GBx2), 240-pin DIMM Upgrade for a Acer Aspire T180 System' (240-pin DIMM 128Mx64 DDR2 PC2-4200) and a part number. > What are the latencies of the different sticks?

Have not tried going in to the BIOS. Don't even know what memory-related settings there may be in there. A few things for me to check out over the next evening or two. TBH I don't know that much about how the timings/latencies may vary. I kind of assumed that the Crucial memory selector would offer 'the right thing' for the model, which I guess it has since the new memory unquestionably works; but I guess it may just not be happy working alongside the old memory. thanks, -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

[Hampshire] reverse DNS lookup tools?
Hi, what tools do people prefer to use to do IP address lookups? I am often in the situation where I see something a bit curious in an Apache server log and want to see where a browser client is coming from. I copy/paste the IP address (e.g. 123.123.123.123) into a shell window to run: $ whois 123.123.123.123 $ nslookup 123.123.123.123 $ dig 123.123.123.123 One of these may come up with something useful such as the organisation or originating country or something to satisfy my curiosity and soothe (or raise) my concerns. But the above set of commands include a load of output that I don't understand and do not always agree on who/where a connection is coming from.

[Hampshire] Ubuntu 8.10 install sticks at disk partition stage

And that was all from the CD's trial mode. However... On trying to do the installation: at disk partitioning stage, select the default "Guided: resize SCSI1(0,0,0) - partition #1(sda) and use freed space" Resizing partition ... Please wait(0%)... and wait... (for 30+ minutes...) and eventually the partitioner fails with a message "An error occurred while writing the changes to the storage devices. The resize operation has been aborted."

2008/12/4 Sean Gibbins <[EMAIL PROTECTED]>: > > That is odd because I thought you were licensing the set(s) at your > address and and not the right to receive and watch broadcasts as such. I believe it is the case that a licence is required if you have a piece of equipment that is capable of receiving broadcast material. If you have a TV screen that you use for watching pre-recorded material but can demonstrate that it is does not have a functioning tuner for off-air reception then you are OK. I do not know if the onus is on *you* to show that your TV set *cannot* pick up live broadcasts or on *"them"* to show that it *can* - i.e. whether you are innocent until proven guilty or vice versa. These days the requirement for a license extends to those who don't use a conventional TV but instead use a laptop or 'media center' PC with a TV tuner card. I think I've also heard rumours of the license mandate being extended to the watchers of 'live' TV feeds over the 'net, but don't quite see how that would work. Several years back I had a contract which involved me living in a rented mobile home on farmland next to the customer's site Monday to Friday. I got a wee 6" portable TV from Radio Shack, and was able to use it without having to obtain a second license because (a) I had a license at my home address and (b) the device was capable of operating on batteries!

[Hampshire] irritating ssh behaviour
I have an Oracle server which I can access with a passwordless ssh login from my desktop, connecting as the 'oracle' user. In ~/.ssh/config, I have: Host qq3 User oracle , and the appropriate setup of id_dsa.pub, authorized_keys2 etc. I do not have an Oracle installation on the desktop machine itself. Running an application that uses the Ora server, I see an Oracle error reported: (ORA-24315: illegal attribute type.) I'd like to see what Oracle has to say about this. I *can* do this: [EMAIL PROTECTED]:~$ ssh qq3 Last login: Thu Nov 27 09:31:26 2008 from obscure.sotn.cable.ntl.com [EMAIL PROTECTED] 12:46 ~]$ oerr ORA 24315 24315, 0, "illegal attribute type" // *Cause: An illegal attribute type was specified for the handle. // *Action: Consult user manual to specify an attribute valid for this handle. [EMAIL PROTECTED] 12:46 ~]$ logout Connection to qq3 closed. However, that means I have to remember to log out of the server so I'd rather just run the oerr command as an argument to the ssh command. Unfortunately, [EMAIL PROTECTED]:~$ ssh qq3 "oerr ORA 12152" bash: line 1: oerr: command not found [EMAIL PROTECTED]:~$ ssh qq3 'oerr ORA 12152' bash: line 1: oerr: command not found Apparently either *my* bash is saying "I know no oerr" so it is not forwarding the command to the remote server, or the oracle user's environment is not getting set up for the execution of the command. My local path: [EMAIL PROTECTED]:~$ echo $PATH /home/victor/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games oracle's path , and access to oerr command, on remote machine: [EMAIL PROTECTED]:~$ ssh qq3 [EMAIL PROTECTED] 13:34 ~]$ echo $PATH /u01/app/oracle/OraHome_1/bin:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home/oracle/bin [EMAIL PROTECTED] 13:36 ~]$ which oerr /u01/app/oracle/OraHome_1/bin/oerr [EMAIL PROTECTED] 13:36 ~]$ ssh-ing in as a different user seems to have odd effects on the environment: [EMAIL PROTECTED]:~$ ssh qq3 "which oerr" which: no oerr in (/usr/local/bin:/bin:/usr/bin) [EMAIL PROTECTED]:~$ ssh qq3 'echo $PATH' /usr/local/bin:/bin:/usr/bin But simple commands are as you would expect: [EMAIL PROTECTED]:~$ ssh qq3 whoami oracle [EMAIL PROTECTED]:~$ ssh qq3 pwd /home/oracle [EMAIL PROTECTED] 13:49 ~]$ cat > ~/bin/hello #!/bin/bash echo Hello [EMAIL PROTECTED] 13:50 ~]$ chmod +x !$ chmod +x ~/bin/hello [EMAIL PROTECTED] 13:50 ~]$ hello Hello [EMAIL PROTECTED]:~$ ssh qq3 hello bash: line 1: hello: command not found [EMAIL PROTECTED]:~$ The ssh man page sayeth: SYNOPSIS ssh [EMAIL PROTECTED] [command] ...

Re: [Hampshire] irritating ssh behaviour
Yep, just so. Path not initialised, profile not executed ... [EMAIL PROTECTED]:~$ ssh qq3 '/u01/app/oracle/OraHome_1/bin/oerr ORA 12152' ORACLE_HOME not set. Please set ORACLE_HOME and try again. Basically I think we are in an analogous situation to when you set up a cron job to run: you get a minimal environment and that is it. So doing everything explicitly does the job: [EMAIL PROTECTED]:~$ ssh qq3 '. .bash_profile ; oerr ORA 12152' 12152, 0, "TNS:unable to send break message" // *Cause: Unable to send break message. Connection probably disconnected. // *Action: Reestablish connection. If the error is persistent, turn // on tracing and reexecute the operation. Trouble is it kind of nullifies the aim of the exercise which was to have a quick (ish) invocation [type "ssh qq3 oerr ", copy-paste in a number, hit Enter). Aliases to the rescue!! [EMAIL PROTECTED]:~$ alias oerr="ssh qq3 '. .bash_profile ; oerr ORA $@'" [EMAIL PROTECTED]:~$ oerr 12152 12152, 0, "TNS:unable to send break message" // *Cause: Unable to send break message.

Of course we have had these discussions before and as I recall one position was that the only time a disk platter is completely safe is when it has been reduced to slag in a furnace.

Sorry to be a pain, but I see a problem if an attendee wants to
register a second MAC. I'd be inclined to leave the MAC data out of
the attendee table altogether. That's what the macs table is for.

[Hampshire] strange emacs behaviour on Ubuntu?
Hello,
something odd just happened.
I tend to keep an emacs -nw session running in a ssh session on a
remote server (yeah, sorry, haven't got my head round 'screen'
yet..;-)
And that is all fine until just now.
I had been doing various stuff inside the emacs , including running
emacs shell windows. Then wanted to set up a cron job.
Now I know better than to try a 'crontab -e' from within an emacs
shell window (since $EDITOR is "emacs -nw"), so I went to another
terminal, did another ssh to that server, and said crontab -e at the
shell prompt. And that shell just stuck; and meanwhile so did my emacs
session. Eventually needed a 3rd shell window to do ps and kill on the
emacs sessions (actually two emacsen, the original one and one for the
crontab edit).
And now, since then whenever I try to run emacs, the shell session
just locks up.
I tried doing a 'strace emacs -nw', and see continuous output of these
lines: (sorry, I don't know what the format should look like. This was
all over my screen with no CR/linefeeds)
--- SIGIO (I/O possible) @ 0 (0) ---
ioctl(0, FIONREAD, [0]) = 0
sigreturn() = ? (mask now [WINCH])
--- SIGIO (I/O possible) @ 0 (0) ---
ioctl(0, FIONREAD, [0]) = 0
sigreturn() = ? (mask now [WINCH])
.. and so on indefinitely, the same lines repeating - until I kill
the emacs and strace commands from another terminal, when some other
stuff comes up:

[Hampshire] tail -f logfile in screen session ... server dies ... coincidence?
I am just wondering ( the way you do when you do something out-of-the-ordinary and something else odd happens...) yesterday I tried setting up a 'screen' session on a remote server for the first time. I am not a screen user but have had it recommended to me by various people. One of the virtual terminals in the screen session was doing a tail -f of a log file, as I recall. This morning the server was deadly slow and unresponsive - not quite dead but bogged down. Am getting the data centre to reboot it as I write. That screen session would not lead to a huge memory footprint ... would it?? -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

[Hampshire] tailing a file as/after it gets rotated?
Hi, I have a log file on a server, which I like to keep an eye on by running tail -f logfile (in fact I then pipe that through other stuff too). This sits in a dedicated screen session. Trouble is the file I am tailing gets moved by a cron job at 06:00 every day and replaced by a new empty one. My tail job keeps watching the old log file even though it has now been renamed by the rotate procedure, and the new logfile is untailed. I am sure this is not a new thing but a (not so) quick google did not come up with a way round this. All I can think of is to have the cron job that rotates the log file send a HUP signal to any process tailing it, but I'm not sure how one would go about that or if that would actually work. (Having just experimented, I suspect not.) ( I have just noticed that this paragraph includes five occurrences of the word 'not', and that's not including these two. ;-) SO, does anybody know of a way to keep a tail on-target when the files get whiked away and replaced? -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

Trouble is, sshd is pretty reticent about the issue so it can be quite hard to determine just what the problem is. I probably should not say this but I have sometimes been (too?) relaxed about group permissions on a box , since usually I am the only user. In fact I wonder if the 'user/group/world' permission model that has been there since the start of the epoch is actually a bit anachronistic. These days I can believe that there are assorted daemons who'd each like a slice of some hardware resource, and so some sharing/locking structure is appropriate, but how many PC's have multiple different human users with conflicting, overlapping access rights such that I and my alter ego can share some things, keep some things to ourselves, but hide others from other alter egos? -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

Munin looks quite comprehensive and specifically says in its FAQ that it is 'complementary to nagios' in that it is plug&play .

[Hampshire] a strange web server anomaly?
This has me really puzzled. I have an Apache setup to write a custom_log with the %D field to tell me the server response time for each request. And I am seeing a very strange pattern. It seems that for one particular client IP address, when the page they are being served includes a particular image, the server frequently times out delivering the image. The image is fine served to other clients; the client IP gets fine response on (some) other pages. It's not particularly big. A small example of the results - format is filename:line-number:IP Address,http status, size, etc. The final field is the time in microseconds): 1. grepping the image: cd /var/log/httpd/ grep -n -e K0002.jpg cus* /dev/null custom_log:1996:194.73.99.134 200 58124 [10/Mar/2009:12:12:34 +] "GET /images/meters/K0002.jpg HTTP/1.1" 90075828 custom_log.1:1946:91.208.3.130 304 - [02/Mar/2009:15:24:53 +] "GET /images/meters/K0002.jpg HTTP/1.1" 241 custom_log.1:5324:194.176.105.49 200 58124 [05/Mar/2009:15:21:56 +] "GET /images/meters/K0002.jpg HTTP/1.1" 47326 custom_log.1:6146:217.33.26.36 200 58124 [06/Mar/2009:15:48:42 +] "GET /images/meters/K0002.jpg HTTP/1.1" 67631 custom_log.10:1372:195.173.32.142 200 58124 [29/Dec/2008:09:56:11 +] "GET /images/meters/K0002.jpg HTTP/1.0" 605584 custom_log.10:1441:195.173.32.179 200 58124 [29/Dec/2008:10:40:48 +] "GET /images/meters/K0002.jpg HTTP/1.0" 113752 custom_log.10:1718:195.173.32.142 304 - [30/Dec/2008:12:03:41 +] "GET /images/meters/K0002.jpg HTTP/1.0" 113 custom_log.10:1766:194.176.105.49 200 58124 [30/Dec/2008:12:26:06 +] "GET /images/meters/K0002.jpg HTTP/1.1" 42906 custom_log.10:1783:195.173.32.179 304 - [30/Dec/2008:12:36:06 +] "GET /images/meters/K0002.jpg HTTP/1.0" 246 custom_log.11:400:195.217.251.188 200 58124 [22/Dec/2008:12:05:45 +] "GET /images/meters/K0002.jpg HTTP/1.1" 246301 custom_log.12:5312:195.93.21.73 200 - [20/Dec/2008:12:49:01 +] "HEAD /images/meters/K0002.jpg HTTP/1.1" 153 custom_log.12:5332:195.93.21.73 200 58124 [20/Dec/2008:12:49:01 +] "GET /images/meters/K0002.jpg HTTP/1.1" 234387 custom_log.13:1834:194.73.99.134 200 58124 [10/Dec/2008:09:14:10 +] "GET /images/meters/K0002.jpg HTTP/1.1" 91120 custom_log.13:1839:194.73.99.134 200 58124 [10/Dec/2008:09:13:26 +] "GET /images/meters/K0002.jpg HTTP/1.1" 90132330 custom_log.13:1842:194.73.99.134 200 58124 [10/Dec/2008:09:13:41 +] "GET /images/meters/K0002.jpg HTTP/1.1" 90035283 386 lines for K0002.jpg 155 >= 90 sec 241 from 194.73.99.134 2. grepping the IP address cd /var/log/httpd/ grep -n -e 194.73.99.134 cus* /dev/null custom_log:1987:194.73.99.134 302 - [10/Mar/2009:12:12:26 +] "POST /bstream/myMeter/intro_bs.pl HTTP/1.1" 273073 custom_log:1988:194.73.99.134 200 18341 [10/Mar/2009:12:12:26 +] "GET /bstream/myMeter/master.pl?CGISESSID=f38f18b093477c93f6543fa178ac8f5c HTTP/1.1" 7369256 custom_log:1989:194.73.99.134 200 1596 [10/Mar/2009:12:12:34 +] "GET /local/QGStyleSheet.css HTTP/1.1" 260 custom_log:1990:194.73.99.134 200 3282 [10/Mar/2009:12:12:34 +] "GET /images/presn/mmw4u.gif HTTP/1.1" 180 custom_log:1991:194.73.99.134 200 15663 [10/Mar/2009:12:12:34 +] "GET /images/presn/SW_Welcome_226x59.png HTTP/1.1" 13087 custom_log:1992:194.73.99.134 200 76 [10/Mar/2009:12:12:34 +] "GET /images/presn/SW_grey_720x2.gif HTTP/1.1" 125 custom_log:1993:194.73.99.134 200 580 [10/Mar/2009:12:12:34 +] "GET /images/presn/TopNav_Highlight_150x40.gif HTTP/1.1" 134 custom_log:1996:194.73.99.134 200 58124 [10/Mar/2009:12:12:34 +] "GET /images/meters/K0002.jpg HTTP/1.1" 90075828 custom_log.13:1825:194.73.99.134 302 - [10/Dec/2008:09:13:14 +] "POST /bstream/myMeter/intro_bs.pl HTTP/1.1" 444074 custom_log.13:1826:194.73.99.134 200 18254 [10/Dec/2008:09:13:14 +] "GET /bstream/myMeter/master.pl?CGISESSID=12b34f1cf1c7ed53b48ef1d356de7909 HTTP/1.1" 11256875 1605 lines from 194.73.99.134 241 occurrences K0002 184 occurrences >=90 sec 3. grepping for >90s response times cd /var/log/httpd/ grep -n -e 9[0-9][0-9][0-9][0-9][0-9][0-9][0-9]$ cus* /dev/null custom_log:1317:195.173.32.179 200 36401 [09/Mar/2009:16:02:17 +] "POST /bstream/myMeter/master.pl?page=Charts&CGISESSID=45373afd8fe16befa1c3deb524ee91b4 HTTP/1.0" 91407681 custom_log:1996:194.73.99.134 200 58124 [10/Mar/2009:12:12:34 +] "GET /images/meters/K0002.jpg HTTP/1.1" 90075828 custom_log.11:1261:195.93.21.73 200 6410706 [23/Dec/2008:14:14:14 +] "POST /bstream/myMeter/master.pl?page=Charts&CGISESSID=f6a4ae7f6cc2c43199e06ea96ef7981a HTTP/1.1" 94657173 custom_log.12:4372:195.10.45.219 200 5322469 [17/Dec/2008:11:15:53 +] "POST /2.3.1/myMeter/master.pl?page=Charts&CGISESSID=96abb78b64b6722ff1eb1a106d5cfa29 HTTP/1.1" 91916041 custom_log.13:1929:194.73.99.134 200 58124 [10/Dec/2008:09:29:19 +] "GET /images/meters/K0002.jpg HTTP/1.1" 90079633 custom_log.13:1935:194.73.99.134 200 58124 [10/Dec/2008:09:31:36 +] "GET /images/meters/K0002.jpg HTTP/1.1" 90044363 custom_l

Interesting. I guess one could look at that by running a tcpdump waiting for a connection from this one address, although I am no TCP/IP expert.

Conventional Wisdom has always been that for computer contractors setting up your own Ltd. Company is the way to go. Indeed, some agencies and some clients require a contractor to have their own limited company in order to do business with them at all. However, there are some 'umbrella organisations' that you can use instead, where (AFAIK) the organisation looks after some of the (from your point of view) overheads such as administering the NI, VAT, etc. It seems that these are more often used by contract project managers and similar professionals on the one hand and IT Support types on the other, but I'd imagine that that is purely coincidental. Certainly the majority of freelance sotware engineers/programmers/whatever-you-call-em have their own ltd company and look after their own NI, Revenue and VAT admin (or else are lucky enough to have an Other Half who can do that!) In fact the (consultant, part time) CTO I report to is a user of one of these umbrella companies so I can ask him for more info if you like. > > I've also been involved in software development and wouldn't mind getting > into quality assurance or system administration. Any advice on transitioning > to either of those? If you find the right sort of role in the right size/type of organisation, that sort of transitioning can just happen.

So for the other stick, latency is 10^9 / 667 = 1.5 MHz, times 5 cycles, also = 7.5 ns. And higher bandwidth because once the pipelines are primed the 800MHz chip pumps the data through at a higher rate. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

[Hampshire] Compatibilty issues installing 64 bit Oracle onto 64-bit Ubuntu
Hi, this is a freshly downloaded x86_64 installation of Ubuntu Server 8.04LTS. q...@pe2950:~$ uname -a Linux pe2950 2.6.24-23-server #1 SMP Mon Jan 26 01:36:05 UTC 2009 x86_64 GNU/Linux Running on a Dell pe2950 (imaginative host naming, huh?) I've downloaded Oracle's 64 bit release 10gR2 : the download filename was 10201_database_linux_x86_64.cpio.gz. However, Oracle only certify this for Red Hat and Suse, not Debian or Ubuntu. By following the usual link-from-a-link-from-a-forum process I have got a good way into the install and am now encountering an error which seems related to a 32/64 bit lib compatibility issue. Log file shows: gcc -m32 -o ctxhx -L/u01/app/oracle/product/10.2.0/db_1/ctx/lib32/ -L/u01/app/oracle/product/10.2.0/db_1/lib32/ -L/u01/app/oracle/product/10.2.0/db_1/lib32/stubs/ /u01/app/oracle/product/10.2.0/db_1/ctx/lib/ctxhx.o -L/u01/app/oracle/product/10.2.0/db_1/ctx/lib/ -ldl -lm -lctxhx -Wl,-rpath,/u01/app/oracle/product/10.2.0/db_1/ctx/lib -lsnls10 -lnls10 -lcore10 -lsnls10 -lnls10 -lcore10 -lsnls10 -lnls10 -lxml10 -lcore10 -lunls10 -lsnls10 -lnls10 -lcore10 -lnls10 `cat /u01/app/oracle/product/10.2.0/db_1/lib/sysliblist` /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.2.4/../../../libpthread.so when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.2.4/../../../libpthread.a when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/bin/../lib/libpthread.so when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/bin/../lib/libpthread.a when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/libpthread.so when searching for -lpthread /usr/bin/ld: skipping incompatible /usr/lib/libpthread.a when searching for -lpthread /usr/bin/ld: cannot find -lpthread collect2: ld returned 1 exit status make: *** [ctxhx] Error 1 Now part of the precursor steps involved various apt-get installs of lib packages including 32 bit compatibility ones such as sudo apt-get install ia32-libs .

So far my googling has been from Oracle/Ubuntu/64-bit entry points; if I google for the 'skipping incompatible' message the proportion of unrelated issues seems to be getting huge. Can anyone suggest what I need to do to get this sorted? No flame war here please, but I would prefer to install it to Ubuntu on the principle of 'if it's you administering it, install what you're familiar with', which is 'buntu in my case. I have not done anything with rpm-based systems for years and apt-* comes more naturally to me nowadays. But I am starting to wonder if going to RH may be the only option left. That seems to be the way some of the rest of the internet has gone. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

I was just deciding at that point that the sensible way to go would be with a Red Hat install, both for level of manufacturer support and for PHB credibility. And I have just wiped Ubuntu off the machine in readiness for putting RH on it ;-( BUT having seen your encouraging post I am going to keep a wee spare partition with a new U64 install on it just to experiment with this issue! Software brings out a stubborn streak in me sometimes... Agree with you about oracle.

Hello again Tony, I have had another go but was not sure exactly which libraries you're referring to. Could you possibly quote the Metalink info?

Sure, a $US 350 per year Red Hat Ent subscription is peanuts compared to how much the time costs that one can spend on this game. (Currently I have the 30 day free "trial" to get going with) TBH I was mainly trying the Ubuntu route because I have a preference for working with Ubuntu nowadays and wanted to see if I could do this, and would feel more at home looking after the box. I have not had to have much to do with RH for a few years now and coming back to it is... (Red Hat Server! Gnome desktop! Log in as root!) weird... And wading through all the Enterprise-speak on the RH site is just - well a bit tacky. It's consistent with Oracle I suppose. But it does mean that the Oracle version should install relatively cleanly on the OS, and the OS should install relatively cleanly on the hardware (that's another story for another post). I have had to divert today onto other tasks so won't be back on this one till later. But thanks to all, especially Tony, for comments & suggestions. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

Re: [Hampshire] [OT]ServerHouse and NewNet
Delving a little further it looks as if NewNet may provide various offerings built on top of ServerHouse facilities, and are to some extent resellers of ServerHouse resources. FWIW, I had seen NewNet mentioned once or twice in Lug discussions about ISPs, and then Google gave me ServerHouse when looking for colo providers, and they turned out to be neighbours.
