Ping and traceroute...
by John Doe 26 Jan '09

26 Jan '09

Hi everybody, Right now, we are blocking pings and traceroutes to our website. But, in order for our members to test the connection when they are experiencing slow browsing, we are thinking about unblocking them... Are there still any security issues (flooding, etc...) in enabling them or is that an old problem fixed a long time ago? Thanks, JD

Hi, Does anybody has any experience with e-sata on CentOS5.2? - How fast is it? Same as an internal sata? - Does it support sata-2? - Does it "hot-plug" like a USB? -- Thanks http://www.911networks.com When the network has to work

OT? File order on CentOS/Samba server
by Miguel Medalha 25 Jan '09

25 Jan '09

I hope someone familiar with the way Linux processes files can enlighten me on the following: I recently replaced an old Windows 2000 server with a new machine running CentOS 5.2. It uses Samba 3.2.7 to serve a network of Windows XP clients. We are a newspaper. We use Acrobat Distiller to batch-convert a folder of single-page PostScript files (for print) to a multipage PDF file (for electronic distribution). Running on a workstation, Distiller watches the folder on a Samba share and does the conversion, automatically creating bookmarks, indexes and other information. On the Windows server, Distiller processes the files by filename order: M09010901A001C.ps M09010901A002C.ps M09010901A003C.ps ... and so on. On the Linux server, Distiller processes the files in an order that seems arbitrary, for example: M09010901A021C.ps M09010901A005C.ps M09010901A015C.ps ... and so on. The order Distiller uses is NOT related to the time stamp of the files. I tried to copy the files to the watched folder one by one in the correct order; the result is the same. This creates the need to open the final PDF and reshuffle the pages by hand, which is very time consuming and prone to error. There is a workaround to this: use the runfilex script that comes with Acrobat: it can contain a list of files to convert, in the order you want. Unfortunately, this is not acceptable for us since the process then takes about 40 minutes (irrespective of platform or filesystem), instead of 3 or 4 minutes. My question is: how is the order of files determined by Linux when a particular order is not explicitly required by a program? I noted the following: I have 4 files in a folder: file1.ps, file2.ps, file3.ps, file4.ps. When I order them by date, they appear in Windows Explorer in, say, the following order: 3, 4, 1, 2 If I copy them to a new folder one by one in the order 1, 2, 3, 4, they will still appear in the order 3, 4, 1, 2 when ordered by date. So, what information is transported with the files that makes the Linux server present them to the world in this order? Does someone know a workaround to this situation or can someone point me to information about file ordering with Linux? By the way, I am using the EXT3 file system. I tried the same on a VFAT file system and the result is the same. It seems to be a Linux thing, not a file system thing. Thank you for your patience.

Problem detecting HP Tape Drive
by Mehdi Sarmadi 24 Jan '09

24 Jan '09

Hello I do have problem using Linux with an external HP tape drive. The server platform is also an HP Server; the server is an HP ML350 G4, and the Tape drive is a HP Storage Works Ultrium 448 - 1U Rack-mountable. HP Ultrium documentation says two drivers should be automatically up, sym53c8xx for LSI SCSI interface "st" for tape and /proc/scsi/scsi should contain information about tape drive, e.g. SCSI ID. However none of them happened in my case! (document: "UP LTO Ultrium 2-3 - Unix Config Guide") The SCSI adapter is an LSI53C1030. The system has another the same adapter which is used for hard disk drives. The interesting part is, the hard disk are detected and even OS boots from them, but I can't make the tape drive work. Moreover, in system boot up, LSI SCSI BIOS displays informations saying there is a tape drive connected! Any one has same experience, suggestion, comments or clues? I've place a zip file here: http://msarmadi.googlepages.com/report_files.zip which contains: - dmesg - lshal - lsmod - lspci -vv - cat /proc/scsi/scsi > proc.scsi.scsi - cat /proc/modules > proc.modules - uname -a > uname Also, below there are detailed information about devices and OS config/log files. ===== System info: Operating System: Redhat Enterprise Linux AS 5(the same thing happened using CentOS 5.2) Sever System: HP ML530 G4 SCSI Adapter: LSI 1030 Tape Drive: HP Storage Works Ultrium 448 - 1U Rack-mountable SCSI Cable: P/N 313375002 Rev R (coming with tape drive) *Note that, no other SCSI devices are connected to the cable. ===== Here is some parts of boot up messages on the screen of HP ML350 G4 ==== System BIOS D17 (14/04/2005) ...

svnserve with SASL on CentOS 5.2
by Ruslan Sivak 23 Jan '09

23 Jan '09

Hello List. I'm cross posting this from svn-users, as I'm not sure whether this is an CentOS specific issue. Perhaps someone here has an idea of what's going on? ----------------------------- I got a fresh install of CentOS 5.2 x32, svnserve, version 1.5.5 (r34862), here is my svnserve.conf file [general] anon-access = none auth-access = write realm = isf [sasl] use-sasl = true min-encryption = 128 max-encryption = 256 and here is my /etc/sasl2/svn.conf file pwcheck_method: auxprop auxprop_plugin: sasldb sasldb_path: /svn/sassl mech_list: DIGEST-MD5 On the client I am using TortoiseSVN 1.5.5 (TortoiseSVN 1.5.5, Build 14361 - 64 Bit , 2008/10/24 18:06:34 Subversion 1.5.4, apr 1.2.12 apr-utils 1.2.12 berkeley db 4.4.20 neon 0.28.3 OpenSSL 0.9.8i 15 Sep 2008 zlib 1.2.3) When connecting to this repository, I am getting "Error: Could not obtain the list of SASL mechanisms". I think I followed the instructions in the svn book : http://svnbook.red-bean.com/en/1.5/svn.serverconfig.svnserve.html#svn.serve…, although the instructions are very sparse. I'm not quite sure hwo sasl is supposed to know to use the svn.conf file to authenticate with svnserve. I am running svnserve from xinetd. Here is my /etc/xinetd.d/svnserve.conf # default: on # Subversion server service svnserve { socket_type = stream protocol = tcp user = root wait = no disable = no server = /usr/bin/svnserve server_args = -i -r /svn port = 3690 } Not quite sure why this isn't working. Does anyone have any ideas? Russ

cpu load monitoring
by Dave Stevens 23 Jan '09

23 Jan '09

Hi, I have a server running Centos 5.2 and am implementing a GIS mapserver app. I have some sample logs from another implementation that give me an idea of bandwidth requirements but I would like to check the cpu load. I can not be at the server during the test and am interested in knowing if there is logging of cpu load available. Anyone have experience with this? Recommendations?
