CentOS 4.4 - Email Out
by Tom Brown 13 Nov '06

13 Nov '06

Hi I need to set some of our boxes to send mail through our smarthost. In the sendmail.mc file i have set the smarthost and rebuilt the sendmail.cf file. When i send a mail locally on the box though i get this error Diagnostic-Code: SMTP; 553 5.1.8 <root(a)localhost.localdomain>... Domain of sender address root(a)localhost.localdomain does not exist What else do i need to edit as there is something that talks about sending from unresolvable domains but this is already allowed i think FEATURE(`accept_unresolvable_domains')dnl any ideas ? thanks

boot issue
by Jerry Geis 13 Nov '06

13 Nov '06

I had to reboot this morning (Dual core AMD 4800+) the machine did not reboot... I thought great its monday. Tried looking at BIOS revisions, looking at BIOS settings, tried changing some and booting again etc... nothing worked. My machine was locking up at Initializing Storage, network audio. I finally noticed I had a thumbdrive in the usb connector. I removed the thumbdrive and the machine booted. Just wanted to share in case someone else gets stuck there. Have a great monday. Jerry

The changer and drive are on the same SCSI ID with a different LUN (I am using an ARCvault 24). I have just installed CentOS 3.8 and after adding support for multiple LUN's, all is detected correctly. I will give this some stress testing over the next few days to hopefully prove all is ok.

Now on boot I get the following error and the Overland Library is not detected. Did you change any options in the LSI scsi bios?

Strange yum behavior
by Itay Furman 13 Nov '06

13 Nov '06

Hello, 'yum search R' returns an impossibly-long list. So I tried 'yum search R.x86_64' and 'yum search R-2.3.0' and few others to no avail. (Google revealed that R package does exist in kbsingh repository.) However, 'yum install R' did offer to install the correct package. Can someone enlighten me as to why did the searches failed or generated a hugh list of alternatives, while the install hit right on the mark? Thanks, Itay FWIW: cat kbsingh-CentOS-Extras.repo [kbs-CentOS-Extras] name=CentOS.Karan.Org-EL$releasever - Stable gpgcheck=1 gpgkey=http://centos.karan.org/RPM-GPG-KEY-karan.org.txt enabled=1 baseurl=http://centos.karan.org/el$releasever/extras/stable/$basearch/RPMS/ # Need a ftp mirror ? uncomment the line below, & disable the one above # baseurl=ftp://rpm.karan.org/pub/kbsingh/el$releasever/extras/stable/$basear… #== 2006-07-10 <itayf(a)fastmail.fm> protect plugin config ==# protect = 0 exclude = *.i386 *.i586 *.i686 includepkgs = darcs darcs-server prozilla R

up2date dependency problem
by Alexey Loukianov 13 Nov '06

13 Nov '06

Greetings, centos. Looks like postinstall scriplet in CentOS4.4 distro requires /sbin/restorecon utility, which in turn resides in policycoreutils package. Meanwhile, up2date don't require policycoreutils. It seems to that there is an error in dependencies for up2date. -- Best regards, Alexey Loukianov mailto:aloukianov@lavtech.ru Software Development Department, Lavtech Corp http://mnogo.ru, http://lavtech.ru
