sendmail refusing incoming connections from outside
by dan1 06 Aug '05

06 Aug '05

Hello. I am scratching my head about sendmail for a simple thing: I have a CentOS 4 box on which I would like to receive e-mails. when I type 'telnet localhost 25' I can connect successfully to the sendmail service. Now if I type: 'telnet 192.168.0.30 25' on the same host the connection is refused. It also refuses connections from another host. I have edited the /etc/mail/access file and added: 192.168 OK But this doesn't help after a restart. Does somebody know why the connection is refused ? I can see that behaviour on several CentOS box I have so it seems to be the new default. What parameter should I change to make it be accepted ? Thank you, Daniel

Dear All, I have two machines, a Centos 3.4 machine and a Centos 4.1 machine. I have used the same sendmail.mc file on each, and 3.4 machine does plain SMTP auth with no problems, compiling the same mc file on the 4.1 machine gives this error: xxxxx [x.x.x.x] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA in the logs, it doesn't even try to authenticate, the cyrus sasl rpm is installed for auth PLAIN It reports this from the EHLO so all looks good: 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH DIGEST-MD5 CRAM-MD5 LOGIN PLAIN 250-DELIVERBY 250 HELP The 3.4 box reports this: 250-ENHANCEDSTATUSCODES 250-PIPELINING 250-8BITMIME 250-SIZE 250-DSN 250-ETRN 250-AUTH LOGIN PLAIN 250-DELIVERBY 250 HELP Any help would be greatly appreciated....

OT: cheap DVD-RAM media?
by Aleksandar Milivojevic 05 Aug '05

05 Aug '05

A bit off-topic. Not a question on how to get it working, but rather question about an practical issue after you get it to work ;-) I got a DVD burner that supports DVD-RAM (in addition to standard DVD+R/-R). I really liked "use it just like hard disk" properties of DVD-RAM, and according to some sources I found, the media itself is more resistant to ageing than standard DVD+R/-R. Great for archiving my data. But the media seems to be quite expensive. I guess mostly because all the places I found were selling it in most expensive option: as single disc in a nice (and useless) case. Haven't found a single place that sells them on spindle. At the end, I ended up buying a 3-pack, with each media in bulky movie-type case (what a waste of space). Does anybody know of any place that sells DVD-RAM media cheap (in bulk, on spindle)?

Recommended hardware for a firewall/router?
by Harald Finnås 05 Aug '05

05 Aug '05

Not really a CentOS specific question, but I hope it's ok... I've decided to buy a server to use as a firewall/router instead of the usual Cisco box, simply because I've come to love Firewall Builder and would like to put all my subnets into one firewall. There will be four gigabit interfaces in the box, one of which will be the internet connection (so this one interface will use max. 10 mbit). Question is if any "normal" hardware will be able to handle this if most of the interfaces gets saturated? What chipset / motherboard should I go for? On a sidenote, I've noticed from the subject on some of the most recent messages that Bryans beeing hassled. I dunno what it's really about since I haven't read the messages, but I'd like to say that I consider Bryan to be a valuable asset to this list. Regards, Harald

probes on udp port 500
by Aleksandar Milivojevic 05 Aug '05

05 Aug '05

Last couple of days some of my hosts were probed for UDP port 500 (IKE daemon, used by IPSec for key exchange) from dialup IPs. Don't remember seeing similar probes before. Some new vaulnerability that script kiddies (and pro crackers) are trying out, or is this some old stuff? I do remember there were some security problems with racoon in the past (that were fixed in current CentOS ipsec-tools packages), but don't remember reading anywhere there were any automated tools to exploit it floating around. Or are there some new flaws discovered recently in some IKE implementations? ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Modify rescue mode boot?
by Alberto Gonzalez 05 Aug '05

05 Aug '05

Hi, I have been able to boot with pxe and load linux rescue, it loads loader and ask me lang, keyboard,load base from nfs, etc... then it ask me about mount chroot or skip, I just choose skip to go to shell. What I want is boot in rescue mode and get a shell directly without having to enter lang, keyboard, nfs ip and dir, skip, etc... once booted on shell I want it automatically run a script mounted via nfs /mnt/source/myscript p.e. any idea on how to avoid all those questions from rescue mode?? Thanks.

remove RPMs with cyclic dependancies.
by Dave Gutteridge 05 Aug '05

05 Aug '05

Okay, I tried installing OpenOffice beta, and I think I messed it up, so I wanted to uninstall it. I thought wilcards worked, so I tried: [root@localhost program]# rpm -e openoffice* error: package openoffice* is not installed Okay, so I couldn't figure out how to remove a bunch of RPM packages at once, so I did this: [root@localhost program]# rpm -qa | grep openoffice And proceeded the labourous task of removing all of the RPMs listed one by one. But then I got down to some files that would say: rpm -e openofficeorg-core01-1.9.122-1.i586 error: Failed dependencies: openofficeorg-core01 is needed by (installed) openofficeorg-core08-1.9.122-1.i586 So then I'd remove the dependancy, and guess what?: rpm -e openofficeorg-core08-1.9.122-1.i586 error: Failed dependencies: openofficeorg-core01 is needed by (installed) openofficeorg-core01-1.9.122-1.i586 The two packages are dependant on each other so I can't remove either. *sigh* So, how do I remove them?
