Regd: Source NAT Rule in Cluster Suite Setup
by Balaji 21 Dec '07

21 Dec '07

Dear All, My Requirement is 1. I am taking backup from client to server and i configured floating IP Address at the client 2. From primary or secondary server rsync command will be triggerd via floating IP Address to the client PC I am using the following rules in firewall scripts /sbin/iptables -F INPUT /sbin/iptables -F OUTPUT /sbin/iptables -F FORWARD /sbin/iptables -F RH-Firewall-1-INPUT # Default Rule /sbin/iptables -P OUTPUT ACCEPT /sbin/iptables -P INPUT ACCEPT /sbin/iptables -P FORWARD ACCEPT Rsync Source NAT rules is iptables -t nat -A POSTROUTING -p tcp -s 192.168.13.179 --dport 873 -j SNAT --to-source 192.168.13.83:873 192.168.13.83 is floating ipaddress 192.168.13.179 is primary ipaddress 192.168.13.110 is secondary ipaddress The following rules is working fine . But the problem is at every trigger of rsync command we will restart the iptables and firewall scripts, then only it will works fine. If the services are not restart then it will send the following error message "rsync: failed to connect to 192.168.13.100: Connection timed out (110) rsync error: error in socket IO (code 10) at clientserver.c(94)" I need to solve the following "iptables and firewall restart" issue in Cluster Suite Setup. Can some one throw light on this.

Postfix Configuration Setup for 2+ domains
by Rick Barnes 20 Dec '07

20 Dec '07

Hello, I have a client that wants to have a dedicated smtp sending host. But they have 2 separate domains then that don't want to have share IP address. The reasons from this is long and drawn out. Is it possible to setup postfix in a virtual host config, like apache for example, such that, domainA.com listens and sends on one IP address and domainB.com listens and sends on another address. This host is simply a email forwarding host, so no user accounts are on the server, they have about 5 servers serving websites for 2 domains and subdomains and want email coming from a common source for both domains (this will be the relayhost for the web servers). I have it setup to listen to 2 ip addresses but as of now I get: 220 smtp.domainA ESMTP Postfix on both addresses. Is there a way to have one address show as: 220 smtp.domainA ESMTP Postfix and the other: 220 smtp.domainB ESMTP Postfix More importantly, email send via 1 should look like it came from that domain and email sent to the other look like it came from its domain. I can find info on virtual domains, but its geared for receiving email for multiple domains. Thanks, Rick

Problem after crash during yum update
by Alfred von Campe 20 Dec '07

20 Dec '07

I was doing a "yum -y update" on a CentOS 4.5 system to get to 4.6 when my system froze. I couldn't ping it nor switch to an alternate console. It was completely frozen. The only recourse was to cycle the power. So I did that, and now when I try to do a "yum update" I get the following error: [many package header downloads deleted] tkinter-2.3.4-14.4.el4_6. 100% |=========================| 21 kB 00:00 ---> Package tkinter.i386 0:2.3.4-14.4.el4_6.1 set to be updated ---> Downloading header for oprofile to pack into transaction set. oprofile-0.8.1-33.i386.rp 100% |=========================| 20 kB 00:00 ---> Package oprofile.i386 0:0.8.1-33 set to be updated --> Running transaction check --> Processing Conflict: python-devel conflicts python < 2.3.4-14.4.el4_6.1 --> Processing Dependency: kdebase = 6:3.3.1-6.el4 for package: kdebase-devel --> Processing Dependency: httpd = 2.0.52-32.3.ent.centos4 for package: httpd-manual --> Processing Dependency: xorg-x11-devel = 6.8.2-1.EL.31 for package: xorg-x11-deprecated-libs-devel --> Processing Dependency: rpm = 4.3.3-22_nonptl for package: rpm-build --> Processing Dependency: xorg-x11-deprecated-libs = 6.8.2-1.EL.31 for package: xorg-x11-deprecated-libs-devel --> Processing Dependency: httpd = 2.0.52-32.3.ent.centos4 for package: httpd-suexec --> Processing Dependency: rpm = 4.3.3-22_nonptl for package: rpm-devel --> Finished Dependency Resolution Error: python-devel conflicts with python < 2.3.4-14.4.el4_6.1 Error: Missing Dependency: kdebase = 6:3.3.1-6.el4 is needed by package kdebase-devel Error: Missing Dependency: httpd = 2.0.52-32.3.ent.centos4 is needed by package httpd-manual Error: Missing Dependency: xorg-x11-devel = 6.8.2-1.EL.31 is needed by package xorg-x11-deprecated-libs-devel Error: Missing Dependency: rpm = 4.3.3-22_nonptl is needed by package rpm-build Error: Missing Dependency: xorg-x11-deprecated-libs = 6.8.2-1.EL.31 is needed by package xorg-x11-deprecated-libs-devel Error: Missing Dependency: httpd = 2.0.52-32.3.ent.centos4 is needed by package httpd-suexec Error: Missing Dependency: rpm = 4.3.3-22_nonptl is needed by package rpm-devel From the attached log file, you can see that yum was able to install/ update 120 packages before it crashed.

Resizing a Xen DomU disk image
by Matthew Lind 19 Dec '07

19 Dec '07

Hello Mailing List! A quick question. Has anyone gotten a resize (in my case grown) a Xen DomU disk image? Here is the procedure I have followed: 1. Install a DomU using virt-install Customize xvda to be all one partition ext3 2. On Dom0: dd if=/dev/zero bs=1G count=1 >> <my_disk_image> ll -h (Image is now 1GB larger) xm create <DomU> On DomU: df -h (Size has not changed) shutdown -h now On Dom0: e2fsck -f <my_disk_image> (Errors Bad Magic...) resize2fs -f <my_disk_image> (Errors Bad Magic...) xm create <DomU> On DomU: df -h (Still reports old size) I am assuming that because resize2fs didn't run that the DomU doesn't know about the additional space. Thanks in advance!

Getting email from cron when script is run manually
by Jeff Larsen 19 Dec '07

19 Dec '07

We have some third party software running on a CentOS 4.5 virtual machine. The software is delivered as compiled python and I wrote an init script for it myself (/etc/init.d/gk). Because the software lacks the usual robustness of CentOS services, I have a bash script (/etc/cron.daily/gk-restart) which simply calls "/etc/init.d/gk restart". So, as expected, root gets an email every day when cron runs the script. Here's the puzzling part: If I need to manually restart the service, I will use the command "/etc/init.d/gk restart". But then I get the very same email message from the cron daemon as if the daily cron job had been run automatically. The email is timestamped for the time at which I manually restarted the service. How on earth is the manual restart being monitored by the cron daemon? The init script is full featured and maintains pid and lock files in /var/run and /var/lock/subsys respectively. Is that the connection? Jeff

Hi, I upgraded a Dell C521 from Ubuntu 6.04 to CentOS5.1. The Dell has an NVidia 6150 analog video card. The screen is an LG1952Tx. After the screen blanking goes on, and the screen goes to sleep, the screen goes black except for a blue note saying: analog video, invalid frequency... I have installed the NVIDIA-Linux-x86-100.14.19-pkg1. Everything works great except for the screen sleep...

How to generate UUID for Xen?
by Kai Schaetzl 19 Dec '07

19 Dec '07

The new virtual machine manager in Centos 5.1 displays some weird behavior here and I assume it's because the UUID of one running VM is the same as of a VM that is shut down. I used the same config file template for creating all my test VMs, so several have the same UUID. Didn't produce any problems with xm. But the new VM manager in Gnome shows active and inactive VMs and identifies them by UUID, which results in it trying to mix the status etc. of the active and of the inactive VM. How can I generate a new UUID? I assume there's some checksum in it, so that I can't just make one up?

CentOS-5.1 I need some help with setting up the SELinux context for a custom httpd directory so that I can write log files into it. This is what I have: In my virtual host config file: RewriteEngine on RewriteLog /etc/httpd/virtual.d/trac-rewrite.log # RewriteLogLevel 0=off 1=basic 2=verbose 3+=module developer debuging RewriteLogLevel 0 If /etc/httpd/virtual.d/trac-rewrite.log does not already exists then when I try to start httpd I get this: ---> # service httpd start Starting httpd: [FAILED] Checking /var/log/messages I see this: # tail /var/log/messages Dec 17 16:08:01 inet01 setroubleshoot: SELinux is preventing the /usr/sbin/httpd from using potentially mislabeled files trac-rewrite.log (etc_t). For complete SELinux messages. run sealert -l cfc477ae-0443-44f7-9bd3-4ede69b03a57 Following the suggested remedy I do this: # sealert -l cfc477ae-0443-44f7-9bd3-4ede69b03a57 Summary SELinux is preventing the /usr/sbin/httpd from using potentially mislabeled files trac-rewrite.log (etc_t). Detailed Description SELinux has denied the /usr/sbin/httpd access to potentially mislabeled files trac-rewrite.log. This means that SELinux will not allow http to use these files. Many third party apps install html files in directories that SELinux policy can not predict. These directories have to be labeled with a file context which httpd can accesss. Allowing Access If you want to change the file context of trac-rewrite.log so that the httpd daemon can access it, you need to execute it using chcon -t httpd_sys_content_t.trac-rewrite.log. You can look at the httpd_selinux man page for additional information.

These files tend to only be used when I am working on a new set of rules but I would rather not have this tripwire lurking in the background when I am concentrating on a different type of problem. I tried: # semanage fcontext -a -t httpd_sys_content_t "/etc/httpd/virtual.d(/.*)?" and # semanage fcontext -a -t httpd_sys_content_t "/etc/httpd/virtual.d/*\.log" But that did not make any difference for the current situation. If someone could enlighten me then i would be greatful. I realize that for some the use of SELinux is controversial. However, please do not "advise" me to drop SELinux as a remedy for this problem. We are not going to do that. Usually, we manage to configure our policies to handle situations like this as they arise using audit2allow and audit2why, I just cannot seem to find a way to generalize a solution to this one. P.S. I am a digest subscriber so that message threading is simply not going to work, Sorry, but that is just the way things are. For the same reason I also request the favour of a direct rely in addition to any to the list. Sincerely, -- *** E-Mail is NOT a SECURE channel *** James B.

possible bug 5.1 - possibly more of a package issue

Hi there, not really sure if this is a bug, but more so rather a missing file... I installed a fresh 5.1 copy very minimal - no desktop, etc. Now it came up later that I would need a desktop on this install. So I was going to just groupinstall in the Gnome Desktop. # yum groupinstall "GNOME Desktop Environment" Now while processing the dependencies, it fails out with a dependency for libgaim.so.0 (for package nautilus-sendto). So I tried... # yum provides libgaim.so.0 No results. Ideas? dnk

The objective here is to have a "spare computer" that I can boot up into any of four "modes" depending on what I'm swapping it in for a the moment. For example, I want to be able to boot it up as a webserver, or as a fileserver, or as a LTSP-enabled application server. And so on. I have a computer here with two 300GB hard drives in it, which I plan to split into four 150GB partitions, one for each of my "modes". And I want to install Centos separately and independently into each partition, so I can just tell Grub to boot up using whatever partition I choose. What is the best way to accomplish this? I have a bad feeling that the drive partitioning tool is going to complain about having multiple / partitions unless I take steps to avoid that. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

Re: [CentOS] "multi-boot" drive partitioning
by Brent L. Bates 18 Dec '07

One good thing about a spare UNPLUGGED machine is in case of a lightning strike. We had a customer site get hit by or near by lighting. The unplugged spare wasn't connect in any way shape or form to anything. No power cord, no network connections, nothing. After the strike, they were having problems with their industrial systems and blamed it on the computers we installed. We took the spare system that wasn't plugged into anything, started it up, and things still didn't work. This proved that our system wasn't the problem. It turned out to be their hardware that didn't have adequate surge protection. -- Brent L. Bates (UNIX Sys. Admin.)

./configure perfparse -> "configure: error: required library libgd unusable"
by Rogelio 17 Dec '07

17 Dec '07

I recently had a problem with the configure script from perfparse running properly so that I could 'make install' it to work with Nagios 2.10 on latest CentOS 4.x + RPMForge (see http://readlist.com/lists/centos.org/centos/5/28966.html) Thinking it was a problem that was a result of "yum remove gd", I formatted the box and reinstalled everything. Now, oddly, I still have the same problem, and unlike before (before running "yum remove gd"), I cannot configure it without getting the following error: *************************************************** *************************************************** "checking for gdlib-config... /usr/bin/gdlib-config checking for gdMalloc in -lgd... no configure: error: required library libgd unusable. Install required and dependent files and rerun configure. See config.log or FAQs for details." *************************************************** *************************************************** The part of the config.log which looks relevant to the problem is the following: *************************************************** *************************************************** | /* Override any gcc2 internal prototype to avoid an error. */ | #ifdef __cplusplus | extern "C" | #endif | /* We use char because int might match the return type of a gcc2 | builtin and then its argument prototype would still apply. */ | char gdMalloc (); | int | main () | { | gdMalloc (); | ; | return 0; | } configure:26962: result: no configure:26974: error: required library libgd unusable. Install required and dependent files and rerun configure. See config.log or FAQs for details. *************************************************** *************************************************** and in the configure script, this pertains to the error as well *************************************************** *************************************************** LIBS="-lgd $LIBS" else { { echo "$as_me:$LINENO: error: required library libgd unusable. Install required and dependent files and rerun configure. See config.log or FAQs for details." >&5 echo "$as_me: error: required library libgd unusable. Install required and dependent files and rerun configure. See config.log or FAQs for details." >&2;} { (exit 1); exit 1; }; } fi *************************************************** *************************************************** Any suggestions? This was working (in that I could ./configure, just not "make && make install") before I removed gd, and once I formatted and reinstalled everything fresh, none of it works. Any help in the right direction would be greatly appreciated.

What is the REAL version of Xen in 5.1?
by Ross S. W. Walker 17 Dec '07

17 Dec '07

I have a 5.1 system with Xen installed. The package says 3.0.3, but an 'xm info' shows 3.1. So what is it? Is it 3.0.3 patched to 3.1 or is it 3.1 packaged as 3.0.3? And if it's the former, does anybody have any idea why upstream wouldn't just deploy 3.1 (now 3.1.2) which is more stable? -Ross ______________________________________________________________________ This e-mail, and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.

Instalation with a customized kernel
by Jerome 17 Dec '07

17 Dec '07

Hi all I don't know if it's the right place to ask for this problem. I just install my server with centos4.5, using PXE/http protocol. ALl goes very well. My asking is that i need a customized kernel to use all of the posibilities of my server. This kernel, made as an rpm file, run well on it. But i would like to be able to install the server directly with this kernel, using PXE/http.. As for any reason, i can have in 10 minutes a new fresh server ready installed. Someone can say me where to search? Thank's a lot. Best regards. -- -- Jérôme La télévision est faite pour ceux qui, n'ayant rien à dire, tiennent absolument à le faire savoir. (Pierre Dac)

problems with CentOS chroot
by Maxim Soldatov 17 Dec '07

17 Dec '07

Hello, I've got strange problem with centos (as well as rhel btw) chrooted environment. First of all I created simple directory with only the libs for 'bash' and 'id' tools: ---- # chroot testcase/ bash-3.1# id uid=0 gid=0 groups=0,1,2,3,4,6,10 ---- Yes, I even do not have /etc/ directory inside testcase/ , but id shows groups from the _host_ root account. I tried to create full chroot with all the libs and tools based on debian testing, but the same result: # id uid=0 gid=0 groups=0,1,2,3,4,6,10 but if I do # ls /etc/shadow /etc/passwd /etc/group /etc/group /etc/passwd /etc/shadow then # id uid=0(root) gid=0(root) groups=0(root),1(daemon),2(bin),3(sys),4(adm),6(disk),10(uucp) Args, quite strange for me. I tried to use strace to identify where is the problem, and only one thing I found is 530 error on read() : [cut] open("/etc/group", O_RDONLY|0x80000) = -530 getgroups32(0, NULL) = 7 getgroups32(7, [0, 1, 2, 3, 4, 6, 10]) = 7 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 open("/etc/group", O_RDONLY|0x80000) = -530 write(1, "uid=0 gid=0 groups=0,1,2,3,4,6,1"..., 34) = 34 [cut] 530 is EIOCBRETRY according to errno.h, but, honestly, I do not know what does it mean and what I can do with it.

Re: [CentOS] Expandable network storage
by Ross S. W. Walker 17 Dec '07

17 Dec '07

No it probably would not provide the performance unless run on 10 Gbe. Of course that depends on the number of write transactions, 1Gbe maxs around 100MB/s, so if you need faster performance look elsewhere. I doubt it's reliability too, nbd is a simple protocol, but as such doesn't provide for error recovery. Best bet, build performance storage with redundancy on 1 server, then if budget allows duplicate it on another and use something like drbd to replicate it (synchronous if network speed allows, asynchronous otherwise) for high availability. -Ross -----Original Message----- From: centos-bounces(a)centos.org <centos-bounces(a)centos.org> To: CentOS mailing list <centos(a)centos.org> Sent: Mon Dec 17 04:56:57 2007 Subject: RE: [CentOS] Expandable network storage Hi all, I'm currently thinking about similar configurations, and (also for cost reasons :-) am also thinking about GNBD with two standard servers as a "poor man" redundant storage - but I'm wondering if that gives enough performance for running databases (in my case Oracle) on top of it.

I kind of just sat back and watched it develop. I learned a lot from it all. I have been reading all of the documentation on clustering provided by Centos/Red Hat, and find I travel in circles. I read one chapter and answer a self-imposed question but I end up asking myself another. What I really want to do is have HA for any service I run (which is mostly HTTP, MySQL, FTP, and the common things like that). I want to run that to redundant storage somewhere that is real easy to expand by just adding more hardware (server or disk drive). I started exploring this by using the Cluster Suite as a base and then looked into each aspect of the cluster and invariably got stuck on the storage side of this. I see how I can maybe set this up originally, but the expansion just doesn't seem to be there. I don't really want to go the route of Fibre channels and ISCSI, and would prefer to use common hardware (which sort of suggests GNBD). If anyone cares to offer suggestions, with a pretty clear explanation trail (thanks Ken Price for your link to a step-by-step), I would really like to see it, as I'm not getting anywhere with the documentation. I hope to get some hardware to play with shortly, and maybe that'll make things clearer. I'm sure it one of those deals where once I get it done, it'll be so obvious. I just need a little kickstart to help me get there.

Qlogic HBA scanning issues with CentOS 5.1 ?
by Finnur Örn Guðmundsson 17 Dec '07

17 Dec '07

Hi, I got few servers (IBM HS20,HS21 blades, IBM xSeries 3650 & others) connected to a dual fabric san throught Qlogic HBA's (23xx, 24xx). Multipathing is done with device-mapper-multipath. On CentOS 4.x i can scan for new scsi devices without any problems, get them up with multipathing & use them without any problems. However, after i started installing CentOS 5.1 (did not notice this problem with CentOS 5) i cannot seem to rescan without huge problems. Sometimes when i rescan after presenting a new LUN to the server nothing is detected, and sometimes the device comes in without any problems at all. Sometimes i even loose some paths after rescanning.....again, i had no problems at all with CentOS 4.x. I use the Qlogic script (Dynamic Target and LUN Discovery <http://support.qlogic.com/support/EULATemplate/Template.aspx?TemplateID=9&p…> 2.2) to scan for new luns. Has anyone had any issues with scanning for new devices off san after upgrading to 5.1 ? Thanks, Finnur

CESA-2007-1215-001 CentOS 4.6 i386 Zero Day Updates (Johnny Hughes) ---------------------------------------------------------------------- Message: 1 Date: Sun, 16 Dec 2007 08:52:27 -0600 From: Johnny Hughes <johnny(a)centos.org> Subject: [CentOS-announce] CentOS 4.6 is released for i386, x86_64, s390, s390x and ia64 To: CentOS-Announce <centos-announce(a)centos.org>, distro(a)distrowatch.com Message-ID: <47653BAB.6040308(a)centos.org> Content-Type: text/plain; charset="utf-8" The CentOS development team is pleased to announce the release of CentOS 4.6 for i386, x86_64, s390, s390x and ia64. It is available on all CentOS.org mirrors and via bittorrent, see this link to download ISOs: http://isoredirect.centos.org/centos/4.6/isos/ This release corresponds to the upstream vendor U6 release. Also released in the updates repository for CentOS-4.6 are all updates through December 15th, 2007. The work for the i386 and x86_64 ServerCDs is in progress. If you are currently using another version CentOS-4 version, using this command will upgrade you to CentOS-4.6: yum update -------------------------------------------------------------------- Major changes for this version are: * samba has been updated to version 3.0.25b. This addresses several critical issues affecting interoperability with Windows 2003™ and Windows Vista™ (resolved in recent upstream releases). * autofs5 is included in this release as a Technology Preview. This new version of autofs resolves several long-standing interoperability issues in multi-vendor environments. * There is a technology preview of OpenOffice-2.0 included in the updates directory. You can install this OOo2 preview alongside the current OOo-1.1.5 version, or you may install the OOo2 preview alone. We apologize that this was not included on the ISOs, however it was not on the upstream ISOs and we followed that layout. To List the new OpenOffice-2.0 RPMS with yum use this command: yum search openoffice.org2 | grep i386 | grep -v langpack For finding Language Packs (if you want other than English) do: yum search openoffice.org2 | grep langpack Use "yum install <pkg_name1> <pkg_name2>" to install the packages that you want, or "yum info <pkg_name1> <pkg_name2>" to obtain more information about them. * A new yum included in CentOS-4.6 requires the installation of yum-metadata-parser. The yum-metadata-parser package contains a metadata parser for yum written in C. It speeds up the metadata parsing phase of yum considerably and does not change yum behavior in any other way. Please see the CentOS specific release notes here (or in the main directory on your install media): http://mirror.centos.org/centos/4.6/os/i386/RELEASE-NOTES-en.html detailed upstream release notes here (and in the /NOTES directory on your install media): http://www.centos.org/docs/4/html/release-notes/as-x86/RELEASE-NOTES-U6-en.… CentOS-4 Documentation is here: http://www.centos.org/docs/4/ -------------------------------------------------------------------- All previous released CentOS versions are available at: http://vault.centos.org/ -------------------------------------------------------------------- To stay current with CentOS: Visit our website at http://www.centos.org/ Join the CentOS mailing list at: http://lists.centos.org/mailman/listinfo/centos HowTos and other items on the wiki: http://wiki.centos.org/ Join various team members on IRC at irc.freenode.net #centos -------------------------------------------------------------------- Note: It may take a couple days for some of the external mirrors to catch up. -------------------------------------------------------------------- Enjoy, The CentOS Development Team

Expandable network storage
by Steve Campbell 17 Dec '07

17 Dec '07

I want to thank everyone who has provided insight into my thread about clustering MySql. I kind of just sat back and watched it develop. I learned a lot from it all. I have been reading all of the documentation on clustering provided by Centos/Red Hat, and find I travel in circles. I read one chapter and answer a self-imposed question but I end up asking myself another. What I really want to do is have HA for any service I run (which is mostly HTTP, MySQL, FTP, and the common things like that). I want to run that to redundant storage somewhere that is real easy to expand by just adding more hardware (server or disk drive). I started exploring this by using the Cluster Suite as a base and then looked into each aspect of the cluster and invariably got stuck on the storage side of this. I see how I can maybe set this up originally, but the expansion just doesn't seem to be there. I don't really want to go the route of Fibre channels and ISCSI, and would prefer to use common hardware (which sort of suggests GNBD). If anyone cares to offer suggestions, with a pretty clear explanation trail (thanks Ken Price for your link to a step-by-step), I would really like to see it, as I'm not getting anywhere with the documentation. I hope to get some hardware to play with shortly, and maybe that'll make things clearer. I'm sure it one of those deals where once I get it done, it'll be so obvious. I just need a little kickstart to help me get there. Thanks, Steve Campbell

After 5.1 update $releasever is still 5
by Robert Moskowitz 16 Dec '07

16 Dec '07

I have performed the 5.1 update via the 5 repo on a couple of systems. I then went to switch these systems to my new local repo using ther $releasever variable. It still has the value of 5, not 5.1 Where is this set? Why was it not changed to 5.1? On the one clean install from the 5.1 isos, $releasever is at 5.1 I think.

Samba issue
by William Warren 15 Dec '07

15 Dec '07

for some reason I cannot to my samba server on centos 4.5 with any other linux distro. I have tried pclinuxos, kubuntu, fc7. I have entered the correct credentials in the correct case to no avail. What's funny is my winders machines can connect just fine.

What is equivalent to MS OUTLOOK ?
by Indunil Jayasooriya 15 Dec '07

15 Dec '07

Hi All, I am looking for an open source email client package that is equivalent to MS OUTLOOK. Clients are running Windows XP and Vista and Linux. So the package should be able to run on both Windows And Linux. Mail server is running Ms Exchange. So this client pkg should be able to access Global Address book of the MS Exchange Server just as MS OUTLOOK. What about evolution ? Pls see, below URL http://www.gnome.org/projects/evolution/ Can it do fulfil my requirements? or do you know any other pkg that can fulfil these requirements? -- Thank you Indunil Jayasooriya

file or website upload scripts / programs and security protection
by Robert - elists 14 Dec '07

14 Dec '07

Holiday Greetings! Ummmmm scenario is centos 4.5 standard apache webserver I have a client that is really struggling with website file upload concepts. Ive been googling for some scripts or other programs that allow uploading of files to proper directory(ies) after authentication I am definitely concerned about security issues of course. I have never implemented this before because everyone I have ever given a web address, a login, a password, and directory structure understood what was going on.... till now... Would someone consider and please share url's or other info about what solutions they have implemented for the website upload technically challenged? We do not mind paying if we need to get something that also helps create excellent yet basic websites on the fly too. Thanks! - rh
