I have a curious problem with an old WRT54GL router, which I use as a WiFi access point on my LAN: Internet->ADSL modem->CentOS-7 computer->WRT54GL router The router has always had a slight problem of losing connection every so often - it used to be every couple of days, but recently it has become much more often. My cure was always to disconnect the power from the router for 10

I have a LinkSys WRT54GL router, which I would like to attach to my CentOS-5.6 server, to set up a LAN 192.168.2.* . The server is attached to the internet through a Billion modem/router which has a single ethernet outlet. The instructions for the LinkSys router assume that it is being attached directly to an ADSL modem. But for various reasons I want everything to go through my server. I wonder

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

When I install the two-interfaces files in /etc/shorewall on my FC-5 system (with shorewall-3.2.3) and run "services shorewall restart" I get ------------------------------------------------------ cp -a interfaces masq policy routestopped rules zones /etc/shorewall/ ...

I'm having great difficulty trying to change server on my home LAN. At present 192.168.2.2 is my server, running CentOS-5.6 and connecting to an ADSL modem. I want to change server to another CentOS machine, 192.168.2.5 . The problem is that I cannot get the computers on the system to forget the old server, even when it is completely disconnected, and the new server is connected to the modem.

I have a CentOS-6.2 server in Italy. Every few months the server gets into a strange state and stops working after a power outage. I should say that this does not occur after every power outage; I suspect, but have no real evidence for this, that if the power comes back too quickly then the machine gets confused because it is in the middle of closing down. If I am in Italy the solution is simple;

Has anybody successfully installed CentOS- I tried (several times) installing CentOS-5.6 from a hard disk, and each time it failed after installing all the rpms, with the warning "The installation has tried to mount image #2, but cannot find it on the hard drive." When I pressed the Debug button one time after the failure, it seemed to say that it was looking for the file in

The mirrorlist entry in my Fedora-11 /etc/yum.repos.d/fedora-update.repo reads: mirrorlist=https://mirrors.fedoraproject.org/metalink?repo=updates-released- f$releasever&arch=$basearch As far as I can see, this means that yum is looking for the file metalink at mirrors.fedoraproject.org ? If I try "sudo yum update" I get: ----------------------------------- [tim at elizabeth ~]$

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

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'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

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,

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

Is there such a thing as a CentOS rescue disk? Google gives many links to such a thing, but when I pursue them I do not get to an URL where I can actually download one. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

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

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 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
