dd trough scp with tar
by David Hláčik 25 Apr '08

25 Apr '08

Hi, first i will explain my experiment : We have ESX server running virtual machines .We want to migrate to XEN. As i did not found any tool for transfering ESX to for example real server, or better to XEN --> please correct me if i am wrong , i found following approach : i will inside virtual machine on ESX boot from Live-CD of CentOS , using dd i will transfer images trought scp to CentOs machine with xen. I believe this one should work, machines on ESX are Windows2003 Servers. So what i need to find is how to write a command which will transfer image trought scp , but for faster transfer also compress it before using tar, or gzip. *so my input will be dd if=/dev/sda1 , my output will be gzipped or tarred image on second side. sda1.img.gz* ** Thanks in advance! D.

dying hd on live legacy system...
by Jason Pyeron 25 Apr '08

25 Apr '08

We have an old 3.x server whose hd is dying (kernel: hda: dma_timer_expiry: dma status == 0x61) and accessing certain files just crashes the system with a reboot. We have moved as many files to a nfs server as we could so simply. The system has been heavily modified (all using rpms) from baseline. What is the most practical method to replace the hard drive? -Jason Pyeron -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- - - - Jason Pyeron PD Inc. http://www.pdinc.us - - Principal Consultant 10 West 24th Street #100 - - +1 (443) 269-1555 x333 Baltimore, Maryland 21218 - - - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information.

RHCE Training
by Joseph L. Casale 25 Apr '08

25 Apr '08

I am possibly going to be sent for my RHCE training. Looking at https://www.redhat.com/courses/rh300_rhce_rapid_track_course_and_rhce_exam/… I am thinking the concepts do not look difficult at all, having a manual and instructor makes this look fairly easy actually. The only thing that looks important to take outside of this would be rh253 if I wasn't interested in taking the elementary courses. Anyone done the VT courses? To fit within the budget and get what I think I need, I might take the rh253vt before the rh300. Any thoughts or pointers from guys here who have done all this? Thanks! jlc

ClamAV version(s)
by Sam Drinkard 25 Apr '08

25 Apr '08

I had clamav-milter working as well as clamd, then for some reason clamd stopped and would not create the socket. After much hair pulling, I finally tracked the problem(s) down to /etc/clamd.conf. After commenting all the stuff out that was providing errors, it is now working again. I had somehow mixed versions from sourceforge and centos, and when I could not get things to update correctly, I removed clamav-milter and reinstalled it. My question is about clamd. " clamd --version yields ClamAV 0.88.7/2314/Sun Dec 10 15:02:13 2006 " Is this the most current version available from centos? In the logs, there is a note about it being drastically outdated and pointed me to an FAQ file on clamd. I don't want to go through that hassle of mixing repos and get all fouled up again. Thanks Sam

Networking help
by Chris Mason (Lists) 25 Apr '08

25 Apr '08

I have a centos 4.0 box that has three network interfaces and is used as router. It runs shorewall as a two-ISP firewall for a single LAN. This morning, the motherboard's LAN interface gave trouble, spewing out IRQ problems, so I disabled it and changed the network cards. As I only had two slots, I tried a dual NIC card, but it crashed the system every time. Right now I am trying to fit two single NOCs in and to bring the machine back up. However, I can;t get any traffic to route. The DHCP ADSL card will not get an IP. I have used Kudzu to configure the new cards, turned off Shorewall, but no matter what I do, teh cards can't talk to the WAN or LAN. The ADSL is fine, my laptop gets and IP easily. Any ideas what I need to look for? -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

TCPWrappers + Sendmail = not working
by Sean Carolan 25 Apr '08

25 Apr '08

I have set up entries in /etc/hosts.allow and /etc/hosts.deny as follows: /etc/hosts.allow sendmail : 10.0.0.0/255.0.0.0 sendmail : LOCAL /etc/hosts.deny sendmail : ALL When I try to connect to port 25 from an Internet host via telnet, the server still responds as usual. The only difference I see is this in my /var/log/maillog: Apr 24 15:41:49 server sendmail[20691]: m3OKfna20691: tcpwrappers (otherserver.example.com, xx.xx.xx.xx) rejection How do I make tcpwrappers simply drop the connection? I would prefer to do this with TCP Wrappers, at least until we get our official IPTables firewall policy worked out. thanks Sean

I am stumped to figure out how to logout a user after they run a script interactively when logged into the console. I see how to do it if in x, but this server does not have x installed. Thanks! jlc
