Has anyone succeeded in installing CentOS-6.0 by PXEboot. If so, would you say how you did it, please. I tried (on an HP MicroServer), but gave up in the end and used a USB stick installation instead. But I'd be very interested to know how to do it, for the future. Unfortunately I didn't keep a proper note of my PXEboot attempt, but IIRC the problem was that install.img was not found,

I have a CentOS-5.6 remote server in a house in Italy, where there are occasional thunder-storms. There was one yesterday, when the electricity went off 3 times, for a second or so on each occasion. My server, an HP MicroServer, came back (re-booted) on 2 of the 3 occasions, but not on the third. I assume that the problem arises because the machine does not close down properly. (Although it is

I wonder if anyone has CentOS-6 working on an HP MicroServer? I'm having a problem with the graphics driver for the Radeon HD 4200 graphics card. CentOS-5.6 is working fine on this machine; but at present I only have CentOS-6 running in text mode. The graphics card as given by "/sbin/lspci -m" is ------------------------------- 01:05.0 "VGA compatible controller"

Is there any point in running NetworkManager on a server? The IP addresses of the two server NICS are fixed (192.168.1.2 and 192.168.2.2 .) I'm not clear if it is necessary in some way to run NM on a CentOS system? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland

I'm been running two HP MicroServers as home-servers under CentOS-5.6 for 2 months, and have been very happy with their performance. I'm wondering if there are many other MicroServer/CentOS users around? I've been surprised when looking at the MicroServer forums (eg <<http://www.avforums.com/forums/networking-nas/ 1431514-hp-proliant-microserver-n36l-owners-thread.html>) how

A bit OT, but I'm running CentOS-5.6 on this machine (in fact on two of them) and it seems to run perfectly - I've had no problems at all. Except that I'd like to add a second ethernet port, and am not sure where one can find a card that will fit this machine. As far as I can see, it requires a half-height PCIe card, which seems to be rather a rare animal. (There doesn't seem to

Does anyone know if the program stunbdc, which prints one's IP address, is available in CentOS-5? It comes with the libnice package in Fedora-11. ------------------------------ [tim at rose ~]$ stunbdc -4 stun.ekiga.net Server address: 75.101.138.128 port 3478 STUN transaction started (timeout 600ms).

I have a 1.5TB Western Digital hard disk (WD15EADS-00R6B0) on my CentOS-5.7 server, which has become incredibly slow for some operations, eg rsync, BackupPC archive, e2fsck, although it seems to work fine for ordinary file operations, and "smartctl -a /dev/sdb" does not report any errors. For example, running "e2fsck -p /dev/sdb5" on a 250GB partition on this disk took over 24

I've had a disaster on my home network server; the partition table on the disk containing / has become corrupted, and testdisk has not enabled me to recover the table. If anyone can help with this I should be grateful. However, that is not what I am writing about. I've installed a substitute box - and HP MicroServer - which by a miracle has CentOS-5.6 installed on it. Now I'm

I'm running CentOS-6 on an HP MicroServer with a Billion 5200S modem/router connecting to the internet. I'm running the standard CentOS-6 firewall on the server. (1) I can open port 22 on the Billion, allowing me to ssh in from outside. But for some reason I cannot ping the same address from outside. (I can ping it internally.) Why is this? I'm not sure if the problem lies with the

I bought a very cheap server yesterday - an HP ProLiant micro server for 160 euro (280 euro with 120 cashback, for some reason). But I was surprised when I opened the box to find it didn't come with keyboard or mouse, and doesn't have the old keyboard/mouse sockets, but requires USB versions. Is that the norm nowadays? Is it possible to convert the old keyboard/mouse plugs? Also there is

My HP MicroServer crashes with a kernel panic when booted into kernel-3.10.0-327.3.1.el7.x86_64, but runs perfectly under kernel-3.10.0-229.20.1.el7.x86_64 . I've been trying to save the panic message with kdump, but am not sure how one can configure kdump to do this, if indeed that is possible. -- Timothy Murphy gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin

I'm running a CentOS-5.6 server, which in general runs perfectly. My setting is possibly a little unusual: ADSL -> Billion 5200S RC modem/router -> CentOS-5.6 HP MicroServer -> Linksys WRT54GL router . My daughter is just visiting me, and she has to contact her job using AT&T VPN on her laptop under Windows XP. Unfortunately this does not work on my system when connected to

Is there a web-interface to dovecot under CentOS-6? I want to create a top-level folder (ie at the same level as Inbox) but this doesn't seem to be possible from KMail running on a remote Fedora-6 laptop. I was browsing through the dovecot wiki, and I saw some pictures which seemed to be from a dovecot GUI, but I could not find the name of this program. Alternatively, can I simply create

Anyone got this working over a LAN under CentOS? The instructions claim it is easy to connect after pressing the WPS button on printer and router. Sadly, I don't see a WPS button on my Linksys WRT54GL router. When I press the WPS button on the printer the WiFi icon flashes, but I don't see any attempt to connect in /var/log/messages on my CentOS-5.5 server. Any advice or suggestions

I want to clone a small (80GB) disk on my CentOS server to a large (1.5TB) disk, as smart has been giving me warnings of unreadable sectors. Both disks are Western Digital, and WD has a WD version of Acronis True Image. I'm not sure whether to use this or Clonezilla. My worry with Acronis is that I want to keep the original disk, and I'm not sure from the documentation if True Image

I'm trying to install spamassassin on a postfix/dovecot server, running CentOS-6.4, following the instructions at <http://wiki.centos.org/HowTos/Amavisd>. I think I have taken all the steps indicated, and the configuration seems to pass the tests suggested, although the response is much more sparse than that described: ------------------------ [tim at alfred ~]$ telnet localhost 10024

I've been following the instrunctions in <http://wiki.centos.org/HowTos/Amavisd> for installing Amavisd, Clamav and SpamAssassin on top of postfix/dovecot . Dovecot is working fine, but I want to deal with spam email. (I am using sendmail/dovecot with procmail and spamassassin on another server, but decided to go over to postfix on this server when I saw it is now the CentOS default.)
