Memory leak question
Hi List
One of my servers is acting very strangely memory wise - it has 4GB of
memory and it is always full, and I don't mean in the not a lot of free
memory kind of full, but in the application memory takes more then
3GB kind of full.
I ran a simple script to compare how many resident memory PS reports
compared to what free reports is being used for stuff other then cache
and buffers, and I got these interesting results:
This is a normal which is very loaded and by right - it has a java
application which is set to 2GB heap and uses it just fine:
# ps auwx | perl -nle 'split/\s+/; $sum += $_[5]; END { print sum:
$sum; }'; free
sum: 3158192
total used free sharedbuffers
cached
Mem: 40634124029396 34016 0 20016
360368
-/+ buffers/cache:3649012 414400
Swap: 4194296 3541883840108
So we can see PS reports 3.1GB is used by applications and free reports
3.6GB of used memory (except buffers and cache). so I'm missing about
half a gig, but I don't mind that much.
Here is the broken server:
# ps auwx | perl -nle 'split/\s+/; $sum += $_[5]; END { print sum:
$sum; }'; free
sum: 1367356
total used free sharedbuffers
cached
Mem: 40634124038212 25200 0 35604
726268
-/+ buffers/cache:3276340 787072
Swap: 4194296 6565083537788
which is mind boggling - there's a 2GB difference, about half my total
amount of memory! Where did all my memory gone too ?
Now that server is also constantly spends tons of time in kswapd and on
IO - thrashing if you want and I'm not sure if its a symptom or the
cause.
Do note that both are production servers and I can't really restart them
or anything, even taking down services is a long and annoying process.
Please throw your two cents my way, thanks.

NetworkManager is doing WPA for a long time now (I've been using it more then a year and it had supported WPA all along). NetworkManager is actually a service that your distro should run in its SysV boot sequence (or whatever they use to boot), and then it has a user application (nm-applet for gnome, knetworkmanager for KDE) that is running in each user's session that offers an interface for the user to select networks and input configuration and security details - and the application talks with the service over dbus so you'd need the message-bus service to also work. Any recent Fedora (7 and above I think) should have that configuration by default. -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

I just noticed something else - both servers are running MySQL, and I'm
using htop (instead of top) to look at processes. Now in the good
server htop lists MySQL memory share as 8.5% and the numbers are
VIRT=615M and RES=329M , while in the bad server htop list MySQL as
using VIRT=1364M and RES=409M but lists it as only 3.8% of memory ?!?
both servers carry the same 4GB of physical memory and 4GB swap.

Why can't I connect to a local service ?
I have a really weird problem - maybe it was always like that or it only
happened since I upgraded, I'm not sure -
I have a CentOS 5.1 box and for some weird reason I can't connect using
TCP to a server running on the same machine, either through localhost or
through the eth0 IP address. Connections from outside work great and the
httpd is happily serving users across the network.
When I try to connect, even something simple such as
telnet localhost 80
I get a timeout:

out)
write(2, telnet: connect to address 127.0..., 59) = 59
close(3)= 0
write(2, telnet: Unable to connect to rem..., 63
/etc/hosts.deny was the immediate suspect, but its empty. IPTables was
on, but is set to always allow lo (and port 80 among others) and
turning it off didn't help. So what can I check next ?

httpd is listening on all interfaces (default configuration: Listen *),
and is serving outside requests just fine. Other services have the same
problem - I just used httpd as an example - Specifically I want a local
LDAP server to work, and I can't connect to it, and MySQL only works

Samba success story [Was: AD Integration/Replacement?]
Sorry for raising an old thread (I'm going over my mailing list boxes), but I wanted to share a very much related success story with you. I'm managing a small network (around 20 workstations and 10 servers) which uses a central authentication against a Linux server. Windows workstations are authenticating against and using roaming profiles from a standard Samba 3 installation with an LDAP backend and Linux workstations and servers authenticate directly through LDAP. Setting it up is not difficult. At first I had an opepldap backend and then it was changed for a Novell eDirectory server, but the setup is fairly similar and not hard to do. Even better, the LDAP server is SuSE Linux Enterprise Server 10 which comes with openldap/samba configuration as a PDC out of the box, so almost no tweaking is actually needed. If anyone is interested in more details, email me in private.

Re: Yum - installing 32 bit binaries on 64 bit CentOS
Specifically for Firefox 32bit plugins, another option is to install nspluginwrapper (http://gwenole.beauchesne.info/projects/nspluginwrapper/ ) that allows running 32 bit plugins under Firefox 64 bit. Its probably not available for CentOS4 (I haven't even bothered to check), but there is a source RPM from the site above that you can use. For other 32 bit software, CentOS does not package all 32 bit packages for x86_64 - only the really important stuff (do they offer mplayerplug-in in their 32bit repositories ? I'm not sure), but you can always add another repository that points directly to the 32 bit release: Go to /etc/yum.repos.d locate the CentOS repository file (probably called centos.repo or something) copy it to another file, let's call it centos-i386.repo open the new file for editing and replace every instance of $arch with i386. save and enjoy.

Re: Yum cache for a cluster of clients
Going a bit off the deep end, here's another suggestion: There are other software update managers besides yum in the world, and at this point I want to talk about URPMI - the Mandrive update manager. URPMI can be installed on other operating systems then Mandrive and I've had success using it on CentOS 4 and some Fedora Core (can't remember). URPMI had a few interesting features that do not exist (or are hard to duplicate) in the competitors, one which is relevant to this discussion is the remote update capability: With URPMI installed on all the target machines, you need to only configure installation sources on one machine and push updates remotely from this machine to all the others. One way that I've used it is to have a local machine in the office that is easy to access and has the correct repositories configured, and whenever you need to push updates (lets say - with a cron job) you use it to sync the other machines. If you ever want to change your software repositories configuration - you only change it in one location. The main downside for this is that you can only use repositories that support the URPMI metadata format. It is easy to set up a repository that supports both YUM and URPMI, but in Tom's case if he's going to set up a local CentOS repository then that is going to be a solution of its own without the URPMI setup.

As long as you all of your CentOS hosts use the same mirror (and not a different mirror each time), the caching http proxy will return files from its cache. IIRC, you need to change the yum.conf file to include the proxy configuration option, and modify the repositories definition (in /etc/yum.repos.d/) so that the repositories use the baseurl setting, instead of the mirrorlist setting.

Text editor recommendation
Hi List. My favorite console text editor is mcedit - I don't subscribe to the vi/emacs debate. But occasionally I need to edit rather large files, and mcedit borks at a few megabytes. When this happens I turn to vi (only because its always available while emacs is a non-default installation option - I really don't do the whole vi vs. emacs thing) and at several dozens of megabytes when vi becomes problematic I find that nano sometimes deliver. But now I'm looking into text files several gigabytes in size, and every attempt to open such files in any of the aforementioned options always ends in me having to kill the process after it brings my (not state of the art but still rather capable) computer to its knees. Does such a beast indeed exists ? A text editor that can handle several gigabytes worth of text (hopefully by not trying to load everything into main memory) ? A console based editor would be preferable, but I don't mind X. it doesn't have to be pretty or support funky text handling commands - it just needs to work.

F/LOSS groupware replacement (again)

The main advantage of course is that if your computer is used by more then one person each can have their own group settings. Regardless, alt_shift_toggle will indeed change group when using either shift (and I think that either alt too - depends on your setting of mod1), which is not what Dan was asking about. According to this http://gentoo-wiki.com/HOWTO_X11_Keyboard there is no setting for just left alt + left shift, though there is an option for only left shift and it doesn't look like there are serious technical issues preventing the support for left_alt_left_shift_toggle, so a bug report here https://bugs.freedesktop.org/ would probably help. On a side note - due to the issues Dan is complaining about (ALT+SHIFT +something used as default key bindings for a lot of applications, sometime without the ability to change them), I once tried using the shift + caps lock toggle option but I couldn't get over the habit of pressing alt-shift - muscle memory dies hard ;-) -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

forever), and while its is very nice it is a bitch getting it to work -
at least without a MySQL database - and sometimes it just locks up and
refuses to behave.
If you're willing to pay for commercial software, and I think the fee is
reasonable, you might want to try @mail (atmail) which is one of the
coolest web mail interfaces I've seen to date. They have online demos

Find process id of background ssh?
Hi List. I'm writing a script to automate some system maintenance tasks, and I want to connect over SSH to several remote computers and do stuff on them. I'm using ssh -f to background ssh so I can run the same operation on multiple machines in parallel, otherwise it will be too slow - the maintenance job may take up to a few minutes to run and the script is not supposed to be fully automatic: a human is to monitor the process. But I don't want just to fire and forget the SSH processes - I want to exit from the script only when all the SSH processes have completed. I can do that by monitoring the process ids of the background SSH processes, if I could know them - which I'm having a difficult time detecting. I'm writing in bash, and optimally it would be something like this: for server in 1 2 ...; do ssh -f [EMAIL PROTECTED] 'run maintenance task' pids=$pids $(getSSHpid) done while kill -0 $pids 2/dev/null; do echo Waiting..; sleep 1; done but I didn't manage to find a way to get the process id of the ssh process after it goes to background, other the 'ps'ing for it.

In my office we have a setup using OpenLDAP and Samba to support Linux and MS-Windows Workstations and it works great. From my experience the downside of using the MS ActiveDirectory solution is that its difficult to get the Linux workstations authenticating directly to the LDAP both because the default ActiveDirectory schema does not provide the required properties to support UNIX style authentication and authorization and that in the ActiveDirectory LDAP protocol implementation there are several bug^H^H^H non-conforming implementation details that sometimes cause the openldap client to fail. I've tried several OpenLDAP directory server products, and the most success I had was with SuSE Linux Enterprise Server which works great out of the box and you don't need to deal with the LDAP directory stuff at all - the YaST user management feature works directly with the directory and you don't need to actually know how to set it up. -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Evangelism - Evolution
Speaking about bugs, I would appreciate it if people who use GNOME's Evolution to read mail would subscribe for bug 490241 in GNOME's bugzilla (link below) which I'm trying to promote as a comprehensive list of BiDi editing problems in Evolution. As everyone who ever tried writing Hebrew email (and possibly Arabic also) in Evolution knows, anything other then a few words is very annoying to write as almost any kind of text editing you want to do is messed up horribly in Evolution's mail composer. The ticket above received some notice as one of the developers assigned the correct keyword to the ticket, but otherwise it got no attention what so ever, and I would really like to promote BiDi awareness in Evolution - as currently there is none. If you'd like to help the cause, it easy - just register to GNOME bugzilla (standard procedure with email confirmation) and CC yourself on this bug. If you'd like to comment with your own horror stories go ahead, but please no me too comments - I don't want to SPAM the developers, just get more awareness (I think that the emails that get auto-CCed according to product and component do not receive notification on adding/removing CCs).

No, that is not what it means. Virtual memory amount might be different then physical memory amount due a whole bunch of different reason, swapping being just a single instance and not even the common one. In short, please ask your question again using more exact terms so that we understand what you want to ask. I was using the 1.5GB process only as a (bad) example. If you really want specifics, then said process has about 1.5GB under the virtual column (which can indeed be a lot of different things other then just real + swap, although interestingly this is exactly how 'man top' defines VIRT), about 200MB under resident column, some 8MB under shared, and 1.2GB under SWAP (according to top, not htop - I couldn't get htop to list this). Now according to 'free' only 250MB of swap are in actual use. The way I see it, 'top's SWAP is computed from virtual - resident regardless of how much swap space the process actually uses - so as Gilad said - talking about the virtual image size is next to useless. Anyway, the original question wasn't really about that specific process - I simply figured it as a good example. Obviously I was wrong, but that's ok - I was expecting something like this :-) The real question - as emphasized by all the comments I received - is: can I know how much memory the process is accessing (within some time period) specifically when its more then the total of pages actually held in physical memory. *accessing = reading to or writing from, not just having them assigned to the process. -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

A third completely different computer on a different network with different work loads that also maintains a replica of the first MySQL database is also seeing high IRQ usage. What is the difference between this machine and the other (I understand the other machine works OK) ? Hardware wise and OS wise - nothing. Software wise there are many different things, but most prominently: * it doesn't see the same kind of traffic (which I currently don't think is the issue as the second server above doesn't see any traffic) * It doesn't replicate its databases. -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Linux memory monitoring compared to MS-Windows
Hi List. I heard (but haven't actually seen) that in MS-Windows the system keeps track of some notion of working set, which is supposedly (if I understand correctly) the total size of pages that an application referenced recently - whether these are currently resident or swapped out (see http://msdn2.microsoft.com/en-us/library/ms684891.aspx which is an MSDN article I found on the subject). The way I understand processes normally work (in Linux anyway) is that as long as there is enough memory available the memory manager keeps all pages that an application constantly references in physical RAM, and pages that are not references are swapped out after a while. A good example of such is a long running Java virtual machine process (at least the Sun implementation anyway) that doesn't return unused memory to the operating system letting it being swapped out until its needed again - so I have some jvm process which takes up some 1.5GB of virtual but less then 150MB resident: it was processing a lot of data some time in the past but now its idling. Now (again - according to my understanding) under contention - i.e. when processes need to use more physical memory then what is available - the memory manager keeps swapping stuff in and out of memory in an attempt to satisfy all requests. Under such conditions its might be useful to know - for each process - the amount of physical memory in use, the amount of virtual mapped to the process, but also how much of that virtual memory the process actually tries to use but can't get it all in physical RAM because other processes are also hogging the memory. Does such a thing exist in Linux?

Processing time spent in IRQ handling and what to do about it
Hi List I have a somewhat of a problem but I don't know how serious it is or how to handle it: I manage several servers - quite a nice beasts, HP ML360G5 with 2 x dual Xeons and 4GB ram each. Now one of the production servers is not behaving all that well - it doesn't handle the load as well as I would like it to and its responses are slower then what I would expect according to previous benchmarks (on identical hardware, not on the specific machine). After doing some application testing and optimization, I still do not rule out sub-optimal application behavior, but I noticed something disturbing and I would appreciate some input on that - I use htop to monitor the server's load, and the load average is quite low when the servers suffers under load, and the cpu time bars rarely reach over 50%. Splitting the cpu time display in htop according to system/IO-wait/hard-IRQ/soft-IRQ I can see that a lot of time is spent in the hard-IRQ region - sometimes more then all other regions together. Running some static benchmarks that should mimic the behavior on real load, on identical hardware at the office, I see very little hard-IRQ time if at all. The main difference between the static benchmark and real usage is that the static benchmark only tests the application logic and IO, while real usage also fetches some files served by Apache over HTTP with each request - maybe ~50Kbytes worth of responses are served by Apache for each request to the application. I was thinking that the high IRQ usage is due to high network traffic - could that be the case and could that be affecting the server's performance ?

Something weird is happening
Hi people. I have here a real conundrum for you: I'm operating an IBM server (an X306, I think ? not sure). Anyway it has a weird setup which is mostly my fault - I wanted to run Fedora on it but the driver for the Adaptec controler it uses only works with the RHEL/CentOS 5 kernel, so I installed CentOS 5 and then upgraded everything but the kernel to Fedora 7. But never mind that - Yesterday I upgraded to Fedora 8 and after that the server went caput - I can't log in through SSH or through the console and almost no service manages to start. Looking closely, it appears that it doesn't recognize any user - not regular users and not system users, and as such most services break. Surprisingly, I can get the system recognize users by simply accessing the /etc/passwd file. It looks something like this: # getent passwd root no output here # ls -l /etc/passwd -rw-r--r-- 1 root root ... /etc/passwd # getent passwd root root:x:0:0:root:/root:/bin/bash I could get the server to boot normally and let me log in by editing /etc/rc.sysinit and after the script mounts the file systems I added touch /etc/passwd /etc/group /etc/shadow And now I can log in, but a lot of stuff still doesn't work - for example xinetd doesn't load any services until I do ls /etc/protocols, and chkconfig fails with funny error messages about not being able to list /etc/rc?.d/[SK][0-9][0-9]something. Basically software can't access files until I get a shell to look at them - totally haizenberg style. What's going on ? I think I can work around the problems by doing something like find /etc /dev/null but this whole problem is really silly, am I living in a different reality ? I'd appreciate it if someone can pinch me so I'll wake up from this weird dream. = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Any standard LAN/Wireless router can physically act as an access-point, though not all internal software will let you do that. Optimally you would be able to turn off the NAT that the router is doing between the LAN/Wireless and the WAN port so it would act like an expensive switch. But I have yet to see a built-in router operating system that let you do that. I've successfully used generic WRT54G routers in this capacity by turning off the DHCP service for the local LAN and plugging the outgoing LAN cable into one of the LAN ports, but if you get a WRT54GL (or WRT54G v4 or older) then you can install a third-party operating system that will probably let you do anything you want. I'm using DD-WRT which has a very similar interface to the default Linksys operating system (its based on it) although its much prettier, and in the main wireless configuration page it has a mode setting where one of them is access point.

Most likely you have an active session running locally on the server

Make sure that there isn't any logged in session on the server and try

Multiple LVM support in installers is a problem for most distros - for example, the Fedora disk wizard is really bad in that it either puts each drive in its own LVM or doesn't let you create more then one LVM and you have no control over which is which except for the order that you create partitions.

MySQL replication problem (sort of)
Hi list. I'm (possibly) having a problem with a MySQL replication setup, where replication works well except for one table that doesn't get new rows at all. I'm using a moderately complex replication setup where a remote server is a master to a server running on the local lan and replicates the entire server over an SSH connection (which sometimes go down, but then I restore it and the server just picks up the replication). A third server on the local lan replicates just one schema from the second server and renames it - the reason is that we want a local copy of the log tables that are generated on the production server, w/o overriding the development schema. The problem is that on the second server everything looks peachy - information is coming in and its always up to date, but on the third server on the renamed database one of the log tables is not getting any updates - currently it is stuck with records from yesterday at noon and nothing new is coming in (I currently think its only one that has problems, but I haven't checked all of them). Other tables are getting updates just fine. I don't see any errors in the mysqld.log file and the slave status shows both IO and SQL replication threads running w/o an error. mysqlcheck thinks that all the tables are ok. All the tables use the InnoDB engine and while there is a lot of foreign keying going on, the said problematic table has no foreign keys at all. If I resync the database (using mysqldump --master-data=1) it starts ok, and after a while (about a day) the same problematic table stops getting any new records. I rather not do a resync again because the last dump was already at 3GB of size and it takes several hours to load it into the database - and the next dump will be larger.

Xen to KVM issue
Hi list. I've used Xen to run a VM on my workstation for testing, but for various reasons (one of which is that I didn't like the Fedora 7 libvirt UI and couldn't be bothered to learn the xen command line syntax) I decided that I want to try out KVM. I'm using Fedora 7, and to get a recent kernel I need to use a non-xen kernel (The latest xen enabled kernel for Fedora 7 is 2.6.20, while the latest standard kernel is 2.6.22) - so I can use either Xen or KVM. As KVM (using qemu for IO) supports the Xen image format, I thought I'd give it a try and load the Xen VM. The VM is a Fedora rawhide from about a month ago, and have several kernels installed on it. When I try to boot it with kvm, no matter what kernel I choose, I get these messages when the kernel loads: device-mapper: ioctl: 4.11.0-ioctl (2006-10-12) initialised: [EMAIL PROTECTED] Reading all physical volumes. This may take a while... No volume groups found Volume group VolGroup00 not found Unable to access resume device (/dev/VolGroup00/LogVol01) mount: could not find filesystem '/dev/root' switchroot: mount failed: No such file or directory Kernel panic - not syncing: Attempted to kill init! And that is it. The Xen VM was installed using logical volume management, and it looks like under KVM it doesn't manage to find it. If I understood correctly (and I probably haven't), the para-virtualized Xen VM's kernel was booting using a kernel that is stored on the host's (domain0) file system, right ? how can I mimic the same situation with kvm ? qemu command line takes a -kernel parameter that supposedly would boot the specified kernel image, but I don't know what to give to it and it doesn't seem to like any of the kernel's under the host's /boot directory. Anyway - in case I'm spewing nonsense, feel free to correct me on any aspect that I was wrong with, and I would also appreciate suggestions as to how might I boot my Xen VM under KVM.

How to detect if grub is installed ?
Hi list. I'm using Ubuntu 7.10 devel on two computers, and on both of them I dist-upgraded yesterday. After doing that, both computers suggested I reboot, which I did only on the desktop computer. After reboot the system wouldn't want to start as it appears that grub was removed for some reason, and I got a no bootable system error from the BIOS. My solution was to boot using the Ubuntu desktop CD and choosing boot to 1st harddrive from the boot menu. I haven't restarted my laptop and I fear that it'll have the same problem, and the laptop doesn't have a CD drive (I have a USB connected drive, but its back at the office which I plan not to visit till sunday), so how do I detect it ? I know I can just go ahead and grub-install to be on the safe side, but I'm kind of QAing this issue and I want to know more about what happened as its quite a problematic upgrade situation.

As I already wrote, the upload speed is under 10 Kb. So that doesn't seem to be the problem. 1.5 Mbps is either 96Kbps or 150Kbps up. The 96 type was being phased out by Bezeq a few months back so no one should be using it anymore. I'm using transmission as my torrent client, and I've noticed that when I use a total upload cap of 6KBps, the actual bandwidth usage on the network is closer to 15KBps (which is about 120Kbps and is ok for 150Kbps upstream if you're not doing anything else on the internet). Ktorrent also misses a bit when you set the upstream cap, but not by as much. I haven't tried rtorrent but it may behave closer to transmission then to ktorrent. I suggest you just decrease your upstream throttle until you get good behavior instead of trying to calculate it. I'm currently using a limit of 4KBps up and decreasing it further to 2KBps if I want to use other upstream guzzling software. You probably also want to experiment with different torrent clients to find out which is behaving better for your usage (have you tried to original bittorrent.com client ?

I'd like to comment that Digikam tags can be ordered in a hierarchical fashion - for example, in my albums I have top level people, places and events tags, and then I have tags for each person I wish to tag, each place or each event. It makes is very easy to search for specific things, or just browse around - selecting a top level tag would work as you expect. Also I really like Digikam's way of tagging images - yes, you can edit the image and write down tags manually, or - you can create a tag in the tag tree, and then drag that tag to (one or more) images or drag images to the tag. 5. I want a digital photo manager, not a digital camera manager, and not a sophisticated photo editor - for which separate applications are available. Check. I just mount my camera's card through the card reader, import to Digikam using import folder and manually erase the photos from the card. I think it can manipulate media connected through USB directly ( e.g. connect your camera through USB cable and use the special communications mode to talk to it) Yes it does. you can add your camera to Digikam, and whenever you plug it in you can load Digikam's import dialog which lets you select the pictures you want to import and either download, delete or download and delete (which saves time on the whole process, IMHO). but I like the manual mount + copy approach, not the least because it saves on camera batteries and I think it's also faster as I'm not sure my camera (Canon EOS 350D) supports USB 2 at all. I have no idea why you think so - on the contrary, minimizing the number of human actions and hence time spent with the camera on seems to me to save on batteries. Also - transfer speed has nothing to do with it, unless you refer to import tools' feature to show you thumbnails of the images before you import them, but that is optional - you can start to select and move your photos before the thumbnail generation is complete. I personally no longer use the Digikam camera import feature.

Digikam has several export methods, including the ability to generate HTML files for upload to website (or directly to your web folder if you host your web site locally). I use Gallery2 as well, on a remote server, and Digikam offers an export to remote gallery feature that allows me to easily upload images to Gallery2. -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Postfix configuration issue
It might be the time, but I can't wrap my head around this problem: I have postfix configured as the local MTA for a server that needs to generate some status emails every day (logwatch, etc'), and mail them to the administrator's address which is [EMAIL PROTECTED] , and I've setup an alias: root: [EMAIL PROTECTED] The problem is that the mail server running the mail domain comany.com doesn't like to receive e-mail from addresses in the form of server.comany.com (where server.company.com is local host name that is not visible on the internet) - because it doesn't accept mail from domains that it can't resolve. So mail from [EMAIL PROTECTED] to [EMAIL PROTECTED] gets rejected. I tried to solve the problem by setting postfix's 'myorigin' to company.com so that postfix will send mail as [EMAIL PROTECTED] which is meaningless (there is no such e-mail address), but I don't mind and I can understand what it means and the mail server will be happy (it doesn't actually verify the user part of From addresses). Problem is that postfix now refuses to resolve the alias and instead of sending to the required address, it sends emails from [EMAIL PROTECTED] to [EMAIL PROTECTED], which of course gets rejected because there is no such address. This is because the second caveat of the 'myorigin' setting: # For the sake of consistency between sender and recipient addresses, # myorigin also specifies the default domain name that is appended # to recipient addresses that have no @domain part. So postfix maps 'root' to '[EMAIL PROTECTED]' and then its no longer a local address and so it gets sent on the wire. My current workaround is to set 'myorigin' to valid.company.com, where valid.company.com is the address of another server whose name can be resolved on public DNS server. Of course this is bad. Can any one suggest a better method of getting my log reports ? I rather not have an alias for '[EMAIL PROTECTED]' on the mail server - its a good address for a spam trap, but probably nothing else. -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Sending mail or receiving mail doesn't require an MX. mail to [EMAIL PROTECTED] is valid even if yada.blabla.something.com does not have an MX record, as long as the domain itself resolves to an IP address. If you are checking just for valid domains, i.e. with a valid A records then again, what exactly will this check tell you? Weigh carefully the overhead against the results.

There was recently a gnubies-il thread with the same problem, which appears to be quite common if Google is to be trusted: Ubuntu - which otherwise is a great desktop operating system with shiny and usable GUIs for almost anything - is sorely lacking a normal user interface to broadband dialing (DSL and cable). All other major distros come with one (I recently had to use Fedora 7's and it was almost perfect, and I know Mandriva's which I used many times before would be perfect if it was only slightly less ugly). Currently to get Ubuntu to dial through DSL you need to run pppoe-conf from the command line, and then use the command line commands pon provider and poff provider. One can conceivably setup custom application launchers for both on the desktop's panel, and in combination with some network monitor applet that is setup to only monitor ppp0, it can even be a usable setup. Anyone with a GUI that does PPP or PPPOE? See here https://blueprints.launchpad.net/ubuntu/+spec/pppoeconfig-gtk-frontend for the launchpad blueprint for this problem (can't right now find the bug ticket for this, and its not linked from the blueprint page). The original RP-PPPOE package linked from the above page, contains a gui for controlling RP-PPPOE.

Re: [SUMMARY] Current status of Israeli ISPs
[This is not really a reply to the previous message - I just wanted to keep the thread id] Update on Actcom status, specifically the tech support issue. I had to call Actcom tech support yesterday, complaining that my DSL connection doesn't work, eventually I found out that the issue was a hardware problem on my side (my girlfriend rewired the router incorrectly, connecting the internet port to an unused cable), but I didn't found it until after I finished with the support person. After he couldn't get my router to work by having me trying different settings, the support guy asked me to connect my computer directly to the modem - at which point he found out that I use a Linux desktop. Except for a couple of ahmm..s, a query about my choice of distribution and a recommendation to use Ubuntu, the support guy didn't seem fazed by my use of Linux. After setting up my Fedora 7 to dial up to DSL (which was a simple wizard I needed no help with) everything worked, at which point point the support guy asked for some specific details to document the incident (operating system type and version, router model and modem model). I didn't get specific help for Linux, mostly as I didn't need any, but the tech support didn't seem to have an issue with me using Linux, and seemed versed on the subject - at all times he was professional and helpful - which I can't really say about most tech support calls I've done over the years, but it was exactly the type of service I was used to getting under Actcom. I think I recall the guy's name from when I called tech support before Actcom was bought - so he might be from the original Actcom tech support team (I didn't ask). To sum, the tech support still operates behind Actcom's toll free number (which AFAIK is the only toll free internet support line in Israel), and still seems clueful about Linux. I don't know about the commercial side (my current contract expires on August, after which I'll be able to comment on the issue), but from the support side I have no complaints, and if the sales department don't mess up my contract renewal I will remain a customer of Actcom/Bezeq Beinleumi. -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Hardware Recommendation
Hi All. I'm in the market for a new laptop, and I hope that people on the list can share their experience with current laptops, specifically in regards to Linux compatibility and reliability. I'm interested in spending less money, but still get a brand with good (preferably world-wide) support - otherwise I'd go with a good Thinkpad which I know from experience is a great product, so currently I'm looking at these brands: HP Pavillon Compaq Presario Dell (whatever - can't make heads or tails of their brand names) Also a couple related questions: - Did anyone have any success in getting a brand laptop in Israel without paying the MS-Windows tax ? - Did anyone manage to get a Dell with Ubuntu installed ? From talking to some Israeli sales reps that distribute Dell laptops I got mostly huh?!?s.

You'd need rp-pppoe which is the default pppoe client for most linux distributions.

From my experience with the routers I've used until now, none of them handled high load so well (high load being bittorrent, so probably loads of connections) ... actually I think my newish ADSL router/modem is running Linux, but I never took the time to test it's routing. A lot of routers today use Linux internally, but as suggested previously, I recommend Linksys WRT54G-L. Linksys is very friendly to open source and offers all the GPL software that their router runs, on their web site for free download. Virtually all current alternative firmware for Linux capable routers are originally based on some Linksys firmware. I run WRT54G-L with DD-WRT firmware and I'm very happy with it. It lets me SSH into the router, setup iptables rules as I like, and has many features and options. My experience with load on the router is ok - if you run a busy network behind it (I also manage an office LAN behind such a router) then you might want to increase some limits on the router configuration, but that is very easy to do using the web based interface. I tried several other firmwares, some are pretty advanced and have cool features such as package management, but I went with DD-WRT because I wanted to have a web based configuration GUI that is easy and handles all the important functions. BTW - there are many other routers that will run alternative Linux firmware: look at the OpenWRT web site for a complete list, but I suggest to go with Linksys because they are friendlier to open source - they even have large stickers saying Open Source inside on their packages :-) -- Oded = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

This accounts for the very slow speed, but it also indicates a very serious problem. But 512 is too a nice a number to be attributed to line noise, I think. I would suspect something wacky going on with hardware somewhere - either your DSL modem or the Bezeq DSLAM. 2 - Although I can work, none of the other machines on my network (Linux or Windows) can do anything on the Internet.
