Re: [CentOS] USB disk dropping out under light load

> Simen, > Out of curiosity, that USB Hub you mentioned....is it a "powered" > hub? Have you attempted to directly connect the external USB HDD? > Thanks. Hi Hollen, It is a powered hub. I've restarted my torrent twice, and seen two rather quick failures (twice in a day), so this is a repeatable problem. I've now hooked the disk up on one of the root-ports and will be restarting the download against it. Still - there /should/ not be a problem running over a hub, powered or otherwise. Right? -S > ______________________________________________________________ > H.F. Streit, UNIX Administrator > IMS Group Technician > Southwest Research Institute -- Simen Thoresen, Dolphin ICS

Running iptables/netfilter module connlimit with stock CentOS4
by Andrew Hull 09 Nov '06

09 Nov '06

Greetings folks, I've been researching the various iptables modules that are included with the stock CentOS4 distro; particularly the connlimit module. Is connlimit included by default? I thought it is since performing # iptables -m connlimit --help returns information on connlimit usage along with the general iptables help info: <SNIP> connlimit v1.2.11 options: [!] --connlimit-above n match if the number of existing tcp connections is (not) above n --connlimit-mask n group hosts using mask </SNIP> The library seems to exist also: /lib/iptables/libipt_connlimit.so However, creating a rule that uses connlimit fails: # iptables -A INPUT -p tcp -m connlimit --connlimit-above 2 --dport \ smtp -j REJECT iptables: No chain/target/match by that name # So, am I missing something simple? Or am I limited to using netfilter's patch-o-matic and compiling a custom kernel (that I *really* do not want to do)? Thank you so much, Andrew Hull

CSGFS repository not up-to-date?
by Jay Leafey 09 Nov '06

09 Nov '06

Let me QUICKLY say I'm not complaining here, but is the csgfs repository not being actively maintained? The Red Hat ftp site has much newer versions available than what is currently in the CentOS csgfs repo, at least for the kernel modules. Should I just go ahead and rebuild them from the SRPMs myself, or is this an unintended condition? This has been holding me up from upgrading to the -4.0.3 kernel. It's not a critical problem, but I'd like to keep current if possible. Thanks! -- Jay Leafey - Memphis, TN jay.leafey(a)mindless.com

USB disk dropping out under light load
by Simen Thoresen 09 Nov '06

09 Nov '06

Hi all, I'm running a pretty updated CentOS4 x86_64 server (Still on kernel 2.6.9-42.0.2, but appart from that fully up to date against the official repos) with a USB-disk attached (the USB-disk is a 750G Seagate disk in a Seagate enclosure) over a USB hub. I've noticed several times that after longish periods of activity, the disk drops out (log from last time, below). In this case, the disk activity was generated by running two bittorrent-clients (ie random access r/w patterns) fed by an 2Mbps connection (ie ~200kB/s datarate). I've been able to use the drive for copying multi-GB file-trees from the main disks (it's part of a backup project), so the failure below seems strange, and not related to traffic.

After repowering the disk again, it seems happy, and fsck passes without comments, and restarting the torrent-clients works well, so the data on the disk is at least reasonably intact. Does anyone here have similar experiences or does anyone use USB-disks for any extended period of time? Yours, -S -- Simen Thoresen, Dolphin ICS

request for optimum setup configuration
by Raghavendra Moktali 09 Nov '06

09 Nov '06

hi, I am required to take text/doc files uploaded to a share/directory in a static ip, do some processing on this queue, convert the file format and save the results in a directory for it to be downloaded (or I could upload the same to another share/folder in another static ip). volume of files is about 1-5 files/second of about 50KB to 100KB each and the converting and delivery has to be in near real time. The actual conversion is on external systems on a seperate subnet and this planned server is for just handling the input and output automatically. I do not know yet if i can use a vpn as the server that provides the data allows this or not. I had planned to put up a centos 4.4 based secure ftp server with two diretories one for incomming files and other for completed, both password protected. the access to the directory will be limited to the ip addresses that are using this facility with iptables. Static IP | Firewall------(public ftp) | (private network 192.168.xx)doing the actual sork | could someone with more experience than me (read newbie) comment or suggest a better approach than the one above or point out security issues as the data must be secured at all costs. Thanks for your time. -- rm

Problems with yum/rpm and %pre scriptlet error 255
by James B. Byrne 08 Nov '06

08 Nov '06

I am running xen (2.6.16-xen3_86.1_rhel4.1) on top of a stock CentOS-4.4 installation. I have not added any additional virtual machines however. When trying to install (as root) acrobat reader 7 for Linux from the adobe rpm (AdobeReader_enu.i386 7.0.8-1) I get the following errors: error: %pre(AdobeReader_enu-7.0.8-1.i386) scriptlet failed, exit status 255 error: install: %pre scriptlet failed (2), skipping AdobeReader_enu-7.0.8-1 This occurs whether I use yum or rpm directly to effect installation and whether or not setenforce is 0 or 1 for SELinux. I have looked for similar errors on google but none of the remedies that I have found there seem to work (turning selinux off, using rpm --replacepackages --replacefiles options). Does anyone here have any ideas that they care to share regarding what is likely the problem or how to fix it? Sincerely, -- James B.
