Re: [CentOS] Dual WAN on EL8 desktop.
I think you need policy routing: https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-policy-based-routing-to-define-alternative-routes_configuring-and-managing-networking https://doc.lagout.org/network/inetdoc/Policy_Routing_in_Linux_ENG.pdf Although it may be tempting to use some sort of round-robin, it would be safer to have specific rules based on the destination, so for example you send all web traffic to one ISP and add exceptions to route specific traffic to the second ISP (e.g. streaming platforms), with each rule having a "backup route" to the other ISP.

Is there some simple option in logrotate's conf that could change this behaviour? Or how to fix this. There must be many others who already have run into this issue. Try skeduling a service stop/start instead the SIGHUP the logrotate daemon does. Regards, Timo Check out the man page for vsftpd.conf. vsftpd supports 2 log file formats. The xferlog_file parameter is for the wu-ftpd style log and the vsftpd_log_file is the native format log file. The description of xferlog_file is: xferlog_file This option is the name of the file to which we write the wu- ftpd style transfer log. The transfer log is only written if the option xferlog_enable is set, along with xferlog_std_format. Alternatively, it is written if you have set the option dual_log_enable.

Re: [CentOS] Router for SOHO network - hardware considerations

One extra machine is acting as a router, in that it is installed between the DSL modem and the network, with two Ethernet cards, and it's taking care of DHCP, DNS, NTP and also acts like a proxy (with Squid). It seems quite big and noisy and electricity-consuming to me, so I wonder if there is any small device that could possibly do the job as good, but which would me more adapted : small, solid and cheap (if possible). I imagine some tiny box just with a CPU and a small harddisk, a little RAM and two network interfaces (one out, one in), where I could install a very stripped-down CentOS, and then just forget about it. So far, I've googled a bit, and I've found two things: 1) Pyramid Soekris boards, where I can put something like Pyramid Linux on it.

I'm using it with the original firmware, and I tested OpenWRT on it; next I will try endian, but I have to say that I'm very satisfied with it and I would recomend it: the system is fast and responsive, and the usb port adds really a lot of flexibility (eg. file sharing, usb dongle backup, squid with cache and so on...).

[CentOS] Disable specific LUN on a SCSI bus
Hi all,
do you know if there is a way at boot time do disable specific LUN's on a SCSI
bus of a particular controller?
I'm trying to write an udev rule, but it seems that the system ignores the
vendor model/name of the controller...
For example: I want to disable /dev/sdb; so I gather some information with
udevinfo -a -p /sys/block/sdb and I try to use them to write
/etc/udev/rules.d/10-custom.rules
ID==?:0:1:0, BUS==scsi, DRIVER==sd, SYSFS{model}==DDYS-T36950N,
SYSFS{vendor}==IBM , OPTIONS=ignore_device, OPTIONS+=last_rule
I put the ? on the ID field because I know that the order of the controller
can change (a kernel update could trigger the switch); also I tried with and
without the spaces at the end of vendor and model: no change
Where am I wrong? It is a different way of doing this?
TIA
Ciao

What I would like to do is to have a script run every time that I

All I can come up with from searching wrt cd is details on why one

just want some way of testing for a certain file and running a
specific command if it is found when I enter a working tree. If this
requires testing every directory that I cd to then I can live with
that. If instead one can put a script that runs only when one
enters certain directories then I can live with that as well.
Is there any way to do this?
I did a simple test:
cd /tmp
touch .git
export PROMPT_COMMAND='echo -ne

and now every time I cd on that directory and every time I issue a command (on
that directory) I get the warning.
Of course you can do something more elegant (for example change the color of

Hi Miguel,
you have to edit the allow-query line to allow queries from other host (I have
any there, not localhost) I'm not sure about the syntax but I guess you could
try to put 10.10.80.* or 10.10.80.0/24 there to allow queries from you network
Also remove 10.10.80.0; from listen-on port as it isn't needed (here you can

If there is a way to query yum for the list of installed packages,
that might suffice. Query each computer for the list of installed

Unfortunately, I'm not familiar enough with yum to know if this is possible.

I guess the best way of doing that is via kickstart
I was thinking about yum... you could do
yum list installed | tail -n +4 | awk '{ print $1 }'
but still there is some work to do.
Maybe rpm -qa is a better way to have the list, but still, if you have to

It may depend on whether you work from ISOs or not. Help is welcome if you understand python and use yum. I was just guessing some misconfiguration on my side; I am using mrepo over remote repository with rsync. I don't know much about snakes ;) (http://en.wikipedia.org/wiki/Pythonidae) nor I am a programmer, but if I can be of any help as an alpha or beta tester here I am.

Re: [CentOS] Yum Problem

Thanks, junji aisalen.wordpress.com Linux Registered User #253162 Is this appening even if you put the proxy=http://host:port directive on /etc/yum.conf ? Regards Lorenzo Quatrini Do you mean http_proxy=http://host:port? Yes, it still happens even after I try proxy=http://host:port. Sorry for the delay answer, due to long holiday. Thanks, From 'man yum.conf' the syntax is 'proxy=http://host:port' (not http_proxy) Anyway it may be too that apt.sw.be is busy; you could try to use the local mirror list changing the following lines on /etc/yum.repos.d/rpmforge.repo: #mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge Bye Lorenzo Quatrini ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] forcing device to USB HDD
Israel Garcia ha scritto: Hi, I bought an USB external hdd (500GB) to make my backups using dump... but, sometimes my sever recognize the hdd device /dev/sdb or /dev/sdc... my question is: How can I assign a fixed device for example /dev/sdc to my hdd? remember I use some scripts to do my backup and I am getting errors because the device changes from sdb to sdc and thanks in advance Israel Another quick and dirty way: put a file (maybe an hiden file) on your device, and on top of your script search for that file on the various disks...

I would say mrepo Regards Lorenzo Quatrini ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos I have decided that mrepo is not the right solution for me. I do not want to have to mirror entire repositories in order to get the software that I need and use at the expense of bandwidth and disk space for useless stuff to me. That said, I'm focusing my efforts into attempting a creating/porting of apt-cacher to yum based distributions. I will notify everyone on my progress, as time progresses. James, I was looking exactly for the same thing. I don't have programming skills, but I can do debugging and testing... So if you want we can join our efforts on this project. I also asked the local LUG on some help, maybe we can have other people joining the project.

Re: [CentOS] restrict network access
Arne Pelka ha scritto: Hi, I have two pc using centos 4, these machines need only access to the (big, class b) local network. Because of security reasons the network access should be restricted to this local network - mainly the users of these pc should not be able to access webpages outside of the local network. My problem is, that I have no own centos repository and therefore these two pc need access to the centos mirrors to get updates. What would be the best way to restrict the network access to the local network and allow the access to some external addresses (a centos mirror and maybe some other servers/websites). I was thinking about iptables but I'm not very experienced in this questions - maybe there is an easier way. The configuration with iptables seems to be very complex, I was skimming through some tutorials and the man pages. In thanks and with best reagrds, Arne I would setup a box with a proxy (eg. squid) and grant full internet access only to that box. On the other boxes either remove the default route, or block on the router/firewall internet access. On the proxy you can easily configure proxies for other services too (eg. pop3/imap) and filter out traffic from/to Internet at will (dansguardian/squidguard); on the pc's you just need to setup the proxy on yum.conf to enable yum updates and (if needed) configure the proxy on your browser, you email-client and so on. I'm still on my way to figure out how to implement a simple yum cache/proxy; as soon as I have news I'll let you know, as in that case you don't need anymore to setup squid and the proxy box will be really trivial to setup.

Re: [CentOS] apt-cacher for CentOS
James A. Peltier ha scritto: Hi All, Is there something similar to apt-cacher available for CentOS? I would like to ensure that an application is only downloaded once to the network and not hundreds of times. If there isn't an equivalent, would someone please point me in the direction of how I might accomplish this with CentOS? Hi, after a lot of googling and searching I think I've found something that looks really interesting: http://freshmeat.net/projects/http-replicator I'm testing it right now, it looks really promising.
