Adobe Flash Install Woes
by Chuck 30 Mar '09

30 Mar '09

I am having a hell of a time getting adobe flash to work on a recent 5.2 install. >From rpm install: Running firefox as root -- I have verified there is a symlink in /usr/lib/mozilla/plugins that points to the actual plugin located in /usr/lib/flash-plugins nada. SoI then copied the plugin directly into /usr/lib/mozilla/plugins and eliminated the symlink from the equation. nada. I then installed the plugin into the $HOME/.mozilla/plugins/ directory of a normal user (and making sure everything was read/executable by that user). nada. At no time does the adobe flash pugin ever appear in the plugins panel when viewing Tools->Addons from within the browser. I see no errors or any logs of any kind getting generated anywhere. An rpm check of both firefox and the flash plugin return with no complaints. I see scads of posts on google regarding other adobe flash player woes but none of the solutions i've found so far work. Since most of the sites I require access to, even metalink, required adobe flash this is a show stopper for me. Thanks for any help, CC

Q about 5.3 qt and qgis
by Michael A. Peters 29 Mar '09

29 Mar '09

Guess I'll find out soon enough ... In order to get qgis to build by RPM in CentOS 5.2 I had to update qt - but the shared library did not version - http://forum.qgis.org/viewtopic.php?f=3&t=4423 Since the qt shared library did not version with the minor update to qt, my suspicion (though I don't know for sure as I didn't look at source) is that the minor version bump was a small bug fix that would have likely just been a patch in RHEL. Anyway, I am curious - is the version of qt in rhel/centos sufficient for qgis or does it need the same minor version bump? Anyone on the list build qgis on RHEL 5.3? If so, was the shipped qt library sufficient? If it is not, then I'm thinking the right way to build qgis may be to see if it *really* needs the minor update and patch the makefile if it doesn't (I usually don't like replacing vendor packages).

sylpheed email client oddity
by Frank Cox 29 Mar '09

29 Mar '09

With the Sylpheed email client: Compose a message Click the button to attach a file to that message Attach a file Save the message to draft Compose another message Click the button to attach a file to that message With Sylpheed 2.5.0 on Fedora 10 I see the directory containing the file that I attached when composing the first message, which is what I expect to see. With sylpheed-2.0.4-0.el5.rf on Centos 5, I see the Sylpheed draft folder. To attach another file from the original directory I have to navigate back there. I don't remember it doing that before. Have I screwed up a setting somewhere? I searched through both the Sylpheed preferences and the Gnome preferences and didn't see anything relevant. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com

OT: PCI Slot Adapter for 2.5" HDD?
by Tim Nelson 29 Mar '09

29 Mar '09

Greetings CentOS list! I do apologize in advance for the OT nature of this post. Since many of you have great experience with different hardware platforms, specialized systems, etc I'm hoping someone can help me out. I have a 1U server for a personal project with only two hard drive bays in front. However, I have two PCI-E slots in the back that are unpopulated and two free SATA ports on the motherboard. I'd really like to find PCI slot bracket for mounting a 2.5" laptop HDD or something similar. Something like this would work if it was PCI-E and was readily available: http://www.tomshardware.com/reviews/a-hard-disk-a-pci-slot,1061-3.html I also found a bracket system but its not exactly what I need... http://www.sunbeamtech.com/PRODUCTS/WHEREVER%20PCI%20RACK.HTML Sooo, whether it's an active card that plugs into the PCI-E slot, or just a dumb bracket that holds a HDD drive, either would work. I appreciate any and all pointers you can lend. Again, I apologize for the OT nature of the post. --Tim

LifeKeeper vs RH/CentOS Cluster
by Kwan Lowe 29 Mar '09

29 Mar '09

Hello All: I've configured a few instances of RedHat/CentOS clustering. For basic services such as web, dns, and LDAP it seems to work well. My basic configuration just uses the core services and a DRBD volume for the shared storage. We have some existing LifeKeeper clustered systems. I don't know much about them except that they use a similar hearbeat/shared storage solution. Has anyone here used both and can mention some pros/cons of each? In particular, is there anything that LifeKeeper provides that cannot be replicated via the RedHat/CentOS solution? Thanks all for any input.

lftp SSL_connect error
by Sean Carolan 29 Mar '09

29 Mar '09

I am unable to find any documentation about this error message, perhaps one of you has experienced this as well. We have an FTP server that is configured to accept FTP transactions over SSL. The server is working fine, as I am able to log in with lftp from my test linux machine in the office. None of our data center machines are able to connect so perhaps this is a firewall or NAT issue? Anyway here is the very un-descriptive error message: **** SSL_connect: error:00000000:lib(0):func(0):reason(0) ---- Closing control socket `ls' at 0 [Delaying before reconnect: 18] It just sits there trying to reconnect over and over again. Any ideas?

Installing on partitionable RAID arrays
by RedShift 29 Mar '09

29 Mar '09

Hello Since linux 2.6, the md layer has a feature called partitionable arrays. So instead of having two disks, creating an identical partition table on both and then putting those partitions in RAID 1, you take those two disks and put them in one partitionable RAID 1 array (in mdadm terms, "mdp") and create a partition table on the new RAID device. The advantages are quite clear compared to the old non-partitionable arrays. My question is, is this supported by CentOS? The GTK installer doesn't provide a way to create such an mdp device and the integrated partitioning tool does not see for example md_d0 when I create it manually from the console. Another way to get CentOS on such a configuration would be to do everything manually, thus installing the base system by creating the necessary disk allocations and then rpm -i all the required packages to get it to boot. (I've done this before, it's not a big deal, you just need to follow a certain order - I remember documenting it somewhere but forgot). But since this method is probably not officially documented anywhere or even supported I'll most likely won't get any support if this setup were to fail somehow (like when upgrading between minor versions). I've tried STFW'ing, but searching for centos and partitionable arrays is too ambiguous. Thanks, Best regards, Glenn Matthys

xen serial port access for domu?
by Gordon McLellan 29 Mar '09

29 Mar '09

Is serial port "passthrough" possible for the version of xen that ships with centos 5.2? I've disabled the xen hypervisor serial console, and can see the serial port in dom0. I've masked out the 8250, 8250_pnp and serial_core modules on dom0 and rebooted. xm create domain fails with the error that exactly 4 arguments are required and only 3 were given. Steps I followed: 1) I have xencons=off as a kernel arg for dom0, and when dom0 boots, it finds the serial port. 2) I have blacklisted 8250, 8250_pnp and serial_core, rebooted, no serial port under dom0 3) added the following to my domu config (domu is 32bit centos 5.2, pvm) addirq = [ 4 ] ioports = [ "3f8-3ff" ] 4) now to start the vm and see what happens: # xm create mythserver Using config file "./mythserver". Error: function takes exactly 4 arguments (3 given) My host is 64 bit centos 5.2, domu is 32 bit centos 5.2. I'm running the stock redhat version of xen that ships with el5.2 Any suggestions? -Gordon # uname -a Linux xenmaster.dimension-x.local 2.6.18-92.1.22.el5xen #1 SMP Tue Dec 16 12:26:32 EST 2008 x86_64 x86_64 x86_64 GNU/Linux # xm log [2009-03-28 18:09:41 xend 8017] ERROR (xmlrpclib2:184) function takes exactly 4 arguments (3 given) Traceback (most recent call last): File "/usr/lib64/python2.4/site-packages/xen/util/xmlrpclib2.py", line 162, in _marshaled_dispatch response = self._dispatch(method, params) File "/usr/lib64/python2.4/SimpleXMLRPCServer.py", line 406, in _dispatch return func(*params) File "/usr/lib64/python2.4/site-packages/xen/xend/server/XMLRPCServer.py", line 64, in domain_create info = XendDomain.instance().domain_create(config) File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomain.py", line 238, in domain_create dominfo = XendDomainInfo.create(config) File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 205, in create vm.initDomain() File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 1507, in initDomain self.createDevices() File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 1716, in createDevices self.createDevice(n, c) File "/usr/lib64/python2.4/site-packages/xen/xend/XendDomainInfo.py", line 1189, in createDevice return self.getDeviceController(deviceClass).createDevice(devconfig) File "/usr/lib64/python2.4/site-packages/xen/xend/server/DevController.py", line 80, in createDevice (devid, back, front) = self.getDeviceDetails(config) File "/usr/lib64/python2.4/site-packages/xen/xend/server/iopif.py", line 78, in getDeviceDetails allow_access = True) TypeError: function takes exactly 4 arguments (3 given) Full pvm config file: # cat /etc/xen/mythserver name = "mythserver" uuid = "f06f3124-0f62-9ea6-ae2e-df597103b5de" maxmem = 1024 memory = 512 vcpus = 2 bootloader = "/usr/bin/pygrub" on_poweroff = "destroy" on_reboot = "restart" on_crash = "restart" vfb = [ "type=vnc,vncunused=1,keymap=en-us" ] disk = [ "phy:/dev/vg0/xen_mythserver,xvda,w" ] vif = [ "mac=00:16:3e:0a:bf:d8,bridge=xenbr0" ] pci = [ "0000:05:02.0","0000:06:08.0","0000:06:09.0" ] addirq = [ 4 ] ioports = [ "3f8-3ff" ] # xm info host : xenmaster.dimension-x.local release : 2.6.18-92.1.22.el5xen version : #1 SMP Tue Dec 16 12:26:32 EST 2008 machine : x86_64 nr_cpus : 8 nr_nodes : 1 sockets_per_node : 2 cores_per_socket : 4 threads_per_core : 1 cpu_mhz : 1995 hw_caps : bfebfbff:20100800:00000000:00000140:040ce33d:00000000:00000001 total_memory : 16382 free_memory : 784 node_to_cpu : node0:0-7 xen_major : 3 xen_minor : 1 xen_extra : .2-92.1.22.el5 xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_pagesize : 4096 platform_params : virt_start=0xffff800000000000 xen_changeset : unavailable cc_compiler : gcc version 4.1.2 20071124 (Red Hat 4.1.2-42) cc_compile_by : mockbuild cc_compile_domain : centos.org cc_compile_date : Tue Dec 16 11:51:08 EST 2008 xend_config_format : 2

Minimal Install?
by Norberto Bensa 28 Mar '09

28 Mar '09

Hello list, I'm testing CentOS 5.2 as a possible Xen Server (i.e.: dom0) but the default no-items-selected still installs cups, portmap, and many other thing I don't want in a dom0 installation. I've already removed the packages I don't want, and replaced sendmail with postfix (I need a mailserver because of mdadm/smartd) but there're some executables I don't know what they do (gam_server for example) Two questions: 1) Is there a _real_ minimal install? 2) Is it possible, using yum, to know which packages holds what file? (like dpkg -S in Debian/Ubuntu) Many thanks in advance, Norberto

Installing on LVM on SW-RAID
by Norberto Bensa 28 Mar '09

28 Mar '09

Hello list, I'm trying to install CentOS 5.2 on LVM on a SW-RAID level 1, but I'm unable to understand how to use the installer correctly. What I'm trying to do is emulate something I've already done with another distro where: sda5 \ RAID1 --> /boot sdb5 / sda6 \ RAID1 --> LVM --> /root, /home, /usr, /var... etc. sdb6 / I've succesfully created the raid, and the PV for LVM, but I can't figure out how to create a VG inside the PV. Is it possible using the installer, or should I better install it using one disk, and once installed create the raid/pv/vg, and move everything around by hand? Many thanks in advance, Norberto

CentOS VPN server for iPhone
by Florin Andrei 28 Mar '09

28 Mar '09

So far, OpenVPN has been working very well for me. Unfortunately, the iPhone doesn't have (yet?) an OpenVPN client, so I'm forced to work with what's available. The options are: L2TP, PPTP and IPSec. If you were to install a VPN endpoint on CentOS, which protocol would you prefer? The condition is to avoid shabby VPN servers that make the system less secure. I've seen some PPTP servers for Linux in the past but I was not impressed with their security track record. I'm not necessarily talking about crypto, I'm talking about the way the application is written. Another condition is ease of installation. I will compile from source if I have no other choice, but I'd rather avoid wasting time with that, as I'm quite busy with non-tech things nowadays. If the application is in a repo somewhere, that would be perfect. Thanks! -- Florin Andrei http://florin.myip.org/

I have Cent OS 5.1 I also have http://phpsysinfo.sourceforge.net/ I have asterisk running .

Cannot get CentOS to install
by Michael Peterson 27 Mar '09

27 Mar '09

I used google but did not come up with anything current to solve my problem. I have not tried any other search engines yet. There is not a search for the CentOS list so I am creating a new post. I have tested the CentOS 5.2 and RHEL 5.3 CD's and they passed. I had to use linux mediacheck ide=nodma to get them to pass. The newest releases seem to most times fail with just linux mediacheck. I have tried linux ide=nodma and linux text ide=nodma after trying linux and linux text Anaconda fails on both CentOS 5.2 and RHEL 5.3 in all cases. The system I am trying to install on is running CentOS 3.x. The hardware is P4 2.8 CPU, 512 MB RAM, 120GB 3ware IDE/PATA RAID HD, ATI Video, CDRW CD, Dual Nic, Floppy and IDE/PATA Tape drive. Please provide any options to the kernel that I should try besides the ones mentioned above that fail.

PXE-Kernel crashes with "RAMDISK: incomplete write ..." after modifiying initrd.img
by Frank Thommen 27 Mar '09

27 Mar '09

Hi, to install current PC models (with new Intel NICs) via Kickstart/PXE, I wanted to add the newest e1000e-Treiber to initrd.img. With this modified image, the Kickstart kernel crashes with the following error messages: [...] md: Autodetecting RAID arrays. md: autorun ... md: ... autorun DONE. RAMDISK: Compressed image found at block 0 RAMDISK: incomplete write (20480 != 32768) 6062080 VFS: Cannot open root device "<NULL>" or unknown-block(253,3) Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(253,3) To modify the initrd.img, I took the original CentOS 5.2 image, unpacked with cpio/gunzip and replaced modules/2.6.18-92.el5/x86_64/e1000e.ko with a current version. This driver module had been created on a freshly installed CentOS 5.2 host with kernel 2.6.18-92.el5 and w/o any updates. After adding the driver, I re-archived and re-packed the image and replaced the initrd.img on my tftp server. The new image is considerably bigger than the old one (12 MB vs. 5.7 MB) which puzzles me, as the driver file itself is 2.8 MB (compared to the old e1000e.ko with ca 170 KB) but the resulting modules.cgz is only around 700 KB bigger than the original one. All files have been compressed with `gzip -9`. My PXE bootsettings are: KERNEL CentOS-5.2_64/vmlinuz APPEND initrd=CentOS-5.2_64/initrd.img ramdisk_size=5940 kssendmac ks=http://srv/ks/ks.cgi noipv6 Even raising ramdisk_size doesn't help. At around ramdisk_size=7100 there seems to be an overflow and the size is recounted from zero (?). Any Ideas, how one can/should create an updated and working initrd.img for Kickstart/PXE? A similar question has been asked before on this list and a recommendation was to wait for 5.3. Unfortunately I cannot wait for the next release. Thanks in advance frank

However, it will stop (or at least slow down) the script-kiddies, worms, and others out there who are just scanning for misconfigured or unpatched applications. Switching SSH to a non-standard port completely emptied my log files of bad connection attempts. Now, if someone attempts to break in, it will be VERY obvious in the logs where before, it would have been buried in all of the other garbage. > Prevent weak passwords, possibly use connection throttling > etc etc. Of course. No one is suggesting that changing port numbers is all you need to do. It is just one more thing that you can do to slow down the attackers. -- Bowie

tar with -N option still picking up old files

Hello: I tried this command to tar up a set of data files updated since yesterday (The data directory contains multiple files with varying dates): /bin/tar -z -c -N 2009-03-25 -f /tmp/test.tgz data When I look at the content of the test.tgz file, it looks like it copied the content of the entire directory, not just the newer files.

What about a 32 bit chroot using Mock? I've never done it, but that's what Mock is intended to do. Perl.i386 will run OK in x86_64 and there is a version of perl-Inline-CPP that will allow you to write most of what you want in CPP and wrap it with Perl. -- Mark

64bit Python 32bit c library ...
by Ben 27 Mar '09

27 Mar '09

I have a closed-source 32bit database application running on a 64bit CentOS 5.2 system which is running very well however i am looking at developing some python applications that require access to the data and the vendor only provides a 32bit c library. So while attempting to utilize the library in python with ctypes it became obvious that the 64bit python cannot use the 32bit c library. So what are my choices? 1. is there a way to use the 32bit library in 64bit python i haven't found? 2. install 32bit python on the 64bit system. 'yum list python.i386' shows that 32bit python is not available. 3. manually compile and install 32bit python and _ALL_ its libraries under /opt. has someone already done this? are the RPMs available? let me just say that i am no python expert, yet, so bare with me. Any help would be appreciated. Ben

[OT] Network switches
by Scott McClanahan 27 Mar '09

27 Mar '09

I'm looking to acquire a few new core switches for our network which would be a major upgrade from the cheap unmanaged things we currently have. Basically, just users, servers, and other simple network devices will be plugged into them but I'd like to start doing some testing with iSCSI for various non-production reasons. I have no allegiance to a particular vendor although I do have a Cisco background. I'd like them to be at least 10/100/1000 (no need for power over ethernet) and include many of the features that are most important to me in a managed switch, including: * vlans * mstp or some well established form of per vlan spanning tree * acl's * port mirroring or what cisco calls span sessions * snmp * ssh enabled remote management * support w/ updates and bugfixes I need at least 48 ports per device and obviously would like them to be "fast". Most importantly, I'd like to know what you guys prefer as operations dudes and what pitfalls to avoid. Also, are there other features you folks would demand to have in your switches that I haven't mentioned? I can provide more information if you'd like. Thanks. Oh, cost is sort of an issue (small/medium sized business) but right now insight from you guys is what's important and I can work out the cost issue later. Thanks again.

Dell 120 GB 5400 RPM Encrypted Serial ATA Hard Drive
by Agile Aspect 26 Mar '09

26 Mar '09

Hi - I've been asked to re-partition a Dell 120 GB 5400 RPM Encrypted Serial ATA Hard Drive and install CentOS 5 on the new partition. It's a Dell Lattitude E5400 laptop. Is this even possible with encrypted drives? Does CentOS 5 need special drivers? Any help would be greatly appreciated. -- Agile -- Article. VI.

CentOS 5.2 and wired Ethernet on a Macbook Pro?
by Scott R. Ehrlich 26 Mar '09

26 Mar '09

I recently installed CentOS 5.2 64-bit on a partition on a MacBook Pro 17 inch. It installed just fine, but wired Ethernet is not available. lspci shows it as nVidia...unknown. Is it possible to get wired Ethernet running on this laptop under CentOS without having to create a virtual machine installation of CentOS? If so, what is the magic? Thanks. Scott

Monitoring IP masquerading on LVS load-balancing
by David Dyer-Bennet 26 Mar '09

26 Mar '09

I've got small numbers of connections moving through a load balancer configured in NAT mode. So I've got an iptables table called "nat", which has in it a line "-A POSTROUTING -o eth0 -j MASQUERADE" (lan connect is eth0, private lan inside the cluster is eth1). The load balancer is working; connections made to the virtual ip on that host do get routed to one of the real servers behind this load load balancer. But I want to observe the connections on the load balancer. My first attempt was to use netstat with the --masquerade switch. This produced the result "netstat: no support for `ip_masquerade' on this system." Consistent with this, there is no /proc/net/ip_masquerade. On the other hand, the load balancer *IS* working; those connections *are* getting NATted and routed. Also, lsmod shows varous relevant modules loaded: iptable_nat 40773 1 ip_nat 53101 2 ipt_MASQUERADE,iptable_nat ip_conntrack 91237 5 xt_state,ip_conntrack_netbios_ns,ipt_MASQUERADE,iptable_nat,ip_nat nfnetlink 40457 2 ip_nat,ip_conntrack ip_tables 55329 2 iptable_filter,iptable_nat x_tables 50377 7 xt_state,ipt_REJECT,xt_tcpudp,ipt_MASQUERADE,xt_multiport,iptable_nat,ip_tables So, netstat just isn't somehow the right monitoring tool, right? So what is the right monitoring tool? I need to know the source IP and real-server IP of connections being handled by the load balancer. I don't need a lot showing exactly how each one was handled, but I'd like to be able to determine the state of any connection currently active. How can I do this? -- David Dyer-Bennet, dd-b(a)dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info

Hello again. You were kind enough to give me this advice last December. I've another holiday approaching and thought it was time that I got this sorted. Unfortunately, I'm not sure that I can do this, so I'm asking your opinion. My router is a Netgear DG834G. I can create a service, tell it which ports to open, and say which local IP I want it sent to. However, I can't see any way to set the port to which it should be forwarded as anything other than the incoming port. IOW, I can enable the new service Ext-ssh, which accepts incoming traffic on port 22022, and direct it to my server on 192.168.0.40, but I can't see how to make it send that traffic to port 22 on the server. Am I totally misunderstanding this? Really all I want is to be able to log in to the server if I get an email alert that there is a problem or security updates pending. If I can get this sorted, I'll look again at how to route the IMAP mail through the tunnel too. Anne -- New to KDE4? - get help from http://userbase.kde.org Just found a cool new feature?

ISPConfig & local administration
by Sam Drinkard 25 Mar '09

25 Mar '09

Hi list, I recently installed a package for Centos5.2 called ISPConfig. This was recommended by a buddy of mine who hosts a number of websites for various clients. Although I don't host any websites except my own, there were some features in the package that I did like the looks of. Well, today, I needed to add a new user and group, so while the machine was sitting here, I attempted to use the gui to adduser. For some reason, the process hung and never did come up. I called my buddy about that and he told me we ran through that same scenario with his machine some time back, but I had forgotten about it. The processes were shown in a ps ax as being ready to run, but again, nothing appeared on the monitor. I suspect the ispconfig somehow disables some of, if not all the built in adminstrative functions of the Centos gui, but hoped someone could prove / disprove this fact. It's rather irritating to go thru a manual user creation for me, as cli is not my strong point under Centos. I wound up using webmin to create the user and set the group for the gempak user, and then manually edited the list of allowed users in the gempak group. One thing of note, and not sure it even matters, but I got some messages like this... "Resolved address "xml:readonly:/etc/gconf/gconf.xml.mandatory" to a read-only configuration source at position 0. Then, it wrote out the same thing for position 1 and position 2, with then a warning that python-dbus not installed. I do know there apparently is a difference in python-dbus and dbus-python. Thanks for any input.. Sam

freeradius version
by Kanwar Ranbir Sandhu 25 Mar '09

25 Mar '09

Hi All, The freeradius version in CentOS 5 is ancient, so I've been considering rebuilding the Fedora 10 rpm for freeradius-2.1.3 on CentOS. That means I'll have to maintain the package, and I'm not an uber packager. Normally I wouldn't care, but in this case I do because the freeradius server is going to be critical. So, should I rebuild the F10 rpm, or should I just stick with the version in CentOS 5? Based on what I'm reading, moving to a newer release would be wise. Regards, Ranbir -- Kanwar Ranbir Sandhu Linux 2.6.27.19-170.2.35.fc10.x86_64 x86_64 GNU/Linux 11:37:20 up 19 days, 11:03, 4 users, load average: 0.17, 0.22, 0.18

looking for some advice to monitor network usage in office
by Rudi Ahlers 25 Mar '09

25 Mar '09

Hi all, I've been asked by a college to setup a monitor to monitor a Windows network, but on internet usage. They want to have detailed usage, i.e. on a per IP / PC basis, and if possible to get stats for every protocol, and see over a period of time what goes on. My first though wat ntop, which does all of this, but it doesn't save the data in a DB, so if the server reboots the stats are reset to 0. I also can't get Cacti to give me stats per IP & per protocol (unless someone knows how todo this). I don't yet know the full network layout, but I have a feeling they're using ADSL, and have a Windows Small Business server with ISA, and possible Exchange as well. So, I'm either going to put a CentOS box between the Windows box & ADSL router, or maybe even setup a CentOS Vmware Virtual PC, force all the network to route via the VPS. Does anyone have some suggestions / experience in setting up something like this? P.S. Please don't look at the fact that there's Windows on the network. I use Linux for business purposes, not as a hobby, and we also use Mac & Windows where the situation calls for it. -- Kind Regards Rudi Ahlers

Limiting maildir sizes with Postfix?
by Xn Nooby 24 Mar '09

24 Mar '09

I have a small Squirrelmail server, using Postfix & Dovecot. I am trying to limit the amount of mail a user can get. The "mailbox_size_limit" value does not seem to be being honored. I am using the Maildir directory format. >From googling, it appears that "mailbox_size_limit" applies to a single file (mbox format?), and that it does not work with Maildirs. Is this correct? How should I limit the Mailbox size of the users? I'm not very familiar with Linux "quotas", but I think that is my only other choice.
