I think you can find stuff with Google, for some WinModems, to get them to work on Linux.. As other posters pointed out, these are not true modems and normally require MS Windows to work. Inexpensive junk, installed into new low end boxes for end users. As another poster pointed out, an External Serial Modem will do the trick for you. I believe *any* External Serial Modem will work on Linux, but, I'm not positive of that. Lanny

RHEL5 and CentOS 5 root logins
by Scott Ehrlich 08 Aug '07

08 Aug '07

I found, under a 64-bit CentOS 5 workstation install, it is possible to modify /etc/inittab and add a couple of lines to prevent root from logging into the console. I found, under a 64-bit RHEL 5 server install, adding the same two lines completely breaks the OS, to the point that a reboot after the lines are added, the OS brings you to a fsck-like prompt, and other things break, too. I didn't have time to look at the logs for specifics, if any were recorded. Does anyone know if a CentOS 5 server install option permits locking out root from console login? Does anyone know of a way, in RHEL 5 Server edition, to prevent root from a console login? Thanks. Scott

It seems that only the 320 speed causes a problem. Which is interesting because Dell says that the drive should be able to operate at 320 as well.

Allocating 64 kbits/s out of 256 kbits/s for one LAN behind firewall
by Indunil Jayasooriya 08 Aug '07

08 Aug '07

Hi, I have a CENTOS BOX as a firewall . both iptabes and iproute 2 are running on it. pls see bleow for installed RPMs. [root@firebox ~]# rpm -qa |grep iptables iptables-1.2.11-3.1.RHEL4 [root@firebox ~]# rpm -qa |grep iproute iproute-2.6.9-3.EL4.7 It has 3 ethernet cards. pls see below. eth0 - internet ip (pls asume. 1.2.3.4/29 ). it connects to ISP router. eth1 - 192.168.100.254 eth2 - 192.168.101.254 There are 2 LANs behind this firewall. both LANs have access to internet due to SNAT rules in the firewall. I have given many SNAT rules per ip basic. some users have full access, some have only web and smtp. I have added many forward rules to suit those SNAT rules. All work fine. one LAN is 192.168.100.0/24, while the other LAN is 192.168.101.0/24 Now, I want LAN with 192.168.101.0/24 to allocate 64 kbit out of 256 kbit. the rest for others. I added rules to the firewall. But I still can not allocate 64 kbit for LAN with 192.168.101.0/24 I think I need a PREROUTING chain for LAN with 192.168.101.0/24 Script is given below. INTERFAZ_INT=eth0 FULLBANDWIDTH=256 BANDWIDTH4LAN=64 iptables -t mangle -A PREROUTING -s 192.168.101.0/24<http://192.168.102.0/24>-j MARK --set-mark 0x5 tc qdisc add dev $INTERFAZ_INT root handle 1 htb r2q 4 tc class add dev $INTERFAZ_INT parent 1: classid 1:2 htb rate "$FULLBANDWIDTH"Kbit tc class add dev $INTERFAZ_INT parent 1: classid 1:5 htb rate "$BANDWIDTH4LAN"Kbit tc qdisc add dev $INTERFAZ_INT parent 1:5 handle 5 sfq perturb 10 tc filter add dev $INTERFAZ_INT protocol ip parent 1: pref 1 handle 5 fw classid 1:5 Still no luck. after applying the obove rules, I downloaded an centos ISO image. But , I still can download @ the usual rate. ( i.e 30-33 kbytes per seconds). If these rules work, I will be able to download @ about 8 kbyes per second. (i.e - 8*8 kbit= 64 kbit) That is what I expect ? Where have I gone wrong? -- Thank you Indunil Jayasooriya

CentOS5 pam_mkhomedir
by Peter Huber 08 Aug '07

08 Aug '07

I have a problem creating homedirs on the fly. Since RHEL5 / CentOS5 you have to use pam_oddjob_mkhomedir instead of pam_mkhomedir. Everything is working (the homedir is created) but two things. First on every logon I get the following error message, and I don't know how to fix it: org.freedesktop.DBus.Error.ServiceUnknown: The name com.redhat.oddjob was not provided by any .service files Second: The permissions of the new created homedir is wrong. It should be 700 but it is 755. Can anybody tell me, how to fix these two problems? Thanks Peter

Virtualisation of Netware?
by Nigel Kendrick 08 Aug '07

08 Aug '07

Hi, I am hoping someone can kick me up the learning curve (!) on Virtualization: We have an old piece of data logging software that was written in Turbo Pascal 6 using a file I/O module tuned to Netware and so it expects its data files to be on a Netware server and will not access them locally or via an MS/Samba share - essentially, it uses direct NCP calls for parts of its data access. The logging software was replaced two years ago, but we need occasional access to the data for a minimum of 6 years and so I wondered whether I could virtualize a Netware 3.x/4.x/5.x or 6./x server under Linux (or Win..er..you know..). I have found some articles on Netware 6.5 virtualization but would really appreciate input from anyone actually doing this already - otherwise I'll just have to keep the existing Netware server in the computer room to be fired up about 3-4 times a year 'on demand'. For info, I'm running a Netware 6.5 1-user 'demo' licence - the original install was on Netware 3.12 until the server died and no-one could find the original Netware floppies! Thanks Nigel Kendrick
