squashfs in the hundreds of GB range
by Boris Epstein 23 Feb '11

23 Feb '11

Hello listmates, I am running mksquashfs trying to archive a 400GB+ directory. It has already taken about a day and the resultant archive is only about 40GB thus far and the command is not done yet. Has anyone made a squashfs that size? Is it normal for the process to take this long? If it is not - what am I doing wrong. I am using the most basic syntax: mksquashfs <directory name> <image name> The process is running at 100% CPU. Thanks for any and all help. Boris.

sendmail, port 465/587, auth and imap
by Jobst Schmalenbach 23 Feb '11

Hi. Apologies to the list for sending this twice as I forgot to enter a proper subject line, I wanted to write the content first and then make up the subject line ;-) -------------------------------------------------------------------- I am trying to configure sendmail that is looks up the users credentials to allow them to send email via that server via an imap server on the same machine when sending email while on the road. I can send email when specifying a user that is stored in the servers /etc/shadow ... no problem but I cannot get my head around it how to do make saslauth OR sendmail lookup the user via the imap daemon. This is the working config (mc) for the sendmail daemon when using a locally created user (I knock the PLAIN off once I got it to work): define(`confAUTH_MECHANISMS', `LOGIN PLAIN DIGEST-MD5 CRAM-MD5') TRUST_AUTH_MECH(`LOGIN PLAIN DIGEST-MD5 CRAM-MD5') DAEMON_OPTIONS(`Family=inet, Port=465, Name=MTA-SSL, M=s') etc. How can I make sendmail (or saslauth) to get the user credentials via an imap server running on the same machine (the credentials are from an internal samba server) so I do not need to enter users details twice?

System Log Error
by sync 22 Feb '11

22 Feb '11

When I issue sudo tail -f/var/log/syslog in order to try and track down an external drive problem I get the following: Jan 11 07:56:00 kernel: [17179663.076000] atkbd.c: Unknown key released (translated set 2, code 0x81 on isa0060/serio0).

Jan 11 07:56:11 kernel: [17179674.012000] atkbd.c: Use'setkeycodes e059 <keycode>' to make it known. I have no idea what this means. atkbd presumably means AT keyboard? Can anybody translate the rest and point me at what might be wrong with my keyboard setup? By the way ,the server is CentOS 5.3 x86_64, and kernel version is 2.6.18-128 Thanks....

How much maximum memory will CentOS 5 support? I know it's not 16 GB!
by Aleksey Tsalolikhin 22 Feb '11

22 Feb '11

How much maximum memory will CentOS 5 support, please? The product info page at http://www.centos.org/product.html says 16GB, but I am running 80 GB RAM right now and seeing 80 GB in top. I see the same 16 GB limit on the RHEL page: http://www.redhat.com/rhel/compare/#note_4 The server hardware is capable of 192 GB RAM and I want to add memory, but want to be sure the OS will support it. Is anybody running CentOS 5 or RHEL 5 with 192 GB or more, please? Best, -at

problems with createrepo
by Janez Kosmrlj 22 Feb '11

I run a local repo for our company's packages. Since yesterday we have problems with creating the repo files. When i run "createrepo --update -s sha rpmdir" i get the folowing error: File "/usr/share/createrepo/genpkgmetadata.py", line 249, in ? main(sys.argv[1:]) File "/usr/share/createrepo/genpkgmetadata.py", line 223, in main mdgen.doPkgMetadata() File "/usr/lib/python2.4/site-packages/createrepo/__init__.py", line 368, in doPkgMetadata self.writeMetadataDocs(packages) File "/usr/lib/python2.4/site-packages/createrepo/__init__.py", line 532, in writeMetadataDocs self.primaryfile.write(po.xml_dump_primary_metadata()) File "/usr/lib/python2.4/site-packages/yum/packages.py", line 1032, in xml_dump_primary_metadata msg += misc.to_unicode(self._dump_base_items()) File "/usr/lib/python2.4/site-packages/yum/packages.py", line 866, in _dump_base_items msg = """ UnicodeDecodeError: 'ascii' codec can't decode byte 0xc2 in position 83: ordinal not in range(128) I didn't change anything on the server and it fails on packages that are more than a year old. It usually fails on package number 200-206. When i move the supposedly broken package to a new directory and run createrepo on that directory, then createrepo finishes OK. I googled a bit, but i couldn't find anything useful. Has anyone on this list seen something similar and what was the problem. thanx in advance Janez

funding

Maybe what Centos needs is a bridal registry. Here in the US, an engaged couple can tell their friends what they'd like to be given as wedding presents. They do this by listing items in a registry, in various stores around town. Anyway, the idea is, post stuff you need in a list on your site. Say you need 20 hard drives, or a particular power supply, or whatever items that get consumed in day to day operations. Just list what's needed, who needs it, and whatever info. It doesn't have to be hardware either - just something everyone can agree is OK to list. People visiting the site can look and decide if it's possible to contribute something - even if it's only one new hard drive of the type needed. Or maybe a canister of Columbia's finest coffee. (although I supposed consuming donated foods of any kind from unknown persons is a risk) And should a contributing member have a hardware failure on his own personal workstation, why not ask the world for some charity in return for his/her efforts? Just list what you need, what it is to be used for, and see if we like you enough to give it to you. 'Contributing members' meaning those known to the community, verifiable, and who are putting in the hours, or whatever efforts. And I'm thinking cash donations should be frowned upon because money can be so easily subverted to doing bad things in the world.

iptables question.
by Bill Campbell 22 Feb '11

22 Feb '11

We use a home-brew system similar to fail2ban to block traffic from IP addresses which appear to be doing Nasty Things(tm). The main thing our system does that fail2ban doesn't is to use a central DNSRBL we maintain allowing it to immedatiately ban listed IP addresses the first time they make an attempt to connection without waiting for them to hit a sufficient number of times to bring up the block. This system sends e-mail messages to our security alias whenever a blocking even occurs, either from tcp_wrappers or swatch log watcher. My problem is that occassionally an IP addresses doesn't appear to be blocked as we continue to see the e-mail messages after the blocks are in place. Most frequently these occur from courier-imap failed login attempts, less frequently from sshd. To start, iptables is initialized by setting up a named rule set, say on eth0: # these two set up the rule set. iptables -N csblocks iptables -A csblocks -j RETURN # now add it to input, check csblocks on all new connections. iptables -i eth0 -m state --state NEW -j csblocks #Insert block IP address 1.2.3.4 as first rule in the set. iptables -I csblocks 1 -s 1.2.3.4 -j DROP # now add a rule to prevent IP forwarding on gateway machines. iptables -A FORWARD -s 1.2.3.4 -j DROP # for good measure, null route the IP route add -host 1.2.3.4 reject With all that incoming attempts still seem to get by for a few IP addresses, but certainly not all. Can anybody point out what I'm doing wrong, or why this may happen? Bill -- INTERNET: bill(a)celestial.com Bill Campbell; Celestial Software LLC URL: http://www.celestial.com/ PO Box 820; 6641 E.

java-1.6.0-openjdk.x86_64 keeps clobbering logging.properties
by Jason Pyeron 21 Feb '11

21 Feb '11

It appears that the rpm does not list the logging.properties as a config file, as such every time yum updates the file get overwritten. /usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/lib/logging.properties For now I have a cron job to replace it. Any suggestions? -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is copyright PD Inc, subject to license 20080407P00.
