Routing

Another chance for me to display my ignorance :-) All that follows is based on SuSE 7.0. I am changing our ip address range from 172.19.50.x (255.255.255.0) to 172.16.y.x (255.255.252.0) - reason - more numbers. However, while moving over I need to let machines on both ranges communicate eg. clients printing to print servers etc. Is this possible? If I set up 2 interfaces on the server (derby) with ifconfig eth0:0 172.19.50.2 netmask 255.255.255.0 ifconfig eth0:1 172.16.0.2 netmask 255.255.252.0 and turn ip forwarding on with yast, should machines on the 2 ip ranges be able to communicate. eg. ping each other I've tried it and they don't. Am I trying something silly and if not what other steps do I need? Dave Williams

Well, 172.19.x.x is a 'class B' IP address, so if you use it with no subnet mask at all (ie the default which would be 255.255.0.0 for a class B) you have 65535 potential addresses available to you, in the range 172.16.0.1 -> 172.16.255.254 (172.16.0.0 being considered as the 'network' and 172.16.255.255 the broadcast address). So one option is just to remove the subnet mask completly - but be warned, you would have to do this on all machines in one go - you can't run with subnet masks on some and not on others ... Is this an option ? > However, while moving > over I need to let machines on both ranges communicate eg. clients > printing to print servers etc. It should be, as long as all of your networking uses the IP protocol (ie Samba/Windows networking on IP - not netbeui) > If I set up 2 interfaces on the server (derby) with > ifconfig eth0:0 172.19.50.2 netmask 255.255.255.0 > ifconfig eth0:1 172.16.0.2 netmask 255.255.252.0 what is the output of $netstat -nr on this box ? > and turn ip forwarding on with yast, should machines on the > 2 ip ranges be able to communicate. eg. ping each other You need to ensure that all machines are using either 172.19.50.2 (on the 172.19.50.0 network) or 172.16.0.2 (on the 172.16.0.0 network) as the default router. Then all should be ok (assuming that the router is configured ok - so netstat -nr would tell us that). Kevin.

RE: [suse-linux-uk-schools] the case of the missing network

Without knowing your samba config it's difficult to say... Samba operates as a domain controller either for an NT style network, or for a 95/98 workgroup style network. If you installed printer shares using the latter style, my guess is that your samba server has now decided to become a member of the workgroup. Maybe. In which case you will need to heck the conf file to force it back to NT mode? Likewise your 98 machine needs to use NT style sharing, and it needs to authenticate username/password to an NT(ie Samba) server. Does this describe your setup? -----Original Message----- From: James & Cybèle [mailto:CJC@stonycobbles.freeserve.co.uk] Sent: 30 January 2001 23:17 To: Schools List Subject: [suse-linux-uk-schools] the case of the missing network Fiddled around with printing on the network today....

Re: [suse-linux-uk-schools] Installing LINUX on SCSI - MORE

Found that I had a dodgy SIM, That's why I got the error as the OS was loading into the RAM disk! I have now changed the ram and doing a full install (everything) of V7 (from the LINUX mag). I've used expert mode so that I could control the mount point & partitions of the four HDDs. A couple of questions, 1) Is there a sensible upper limit to the size of the swap partition? 2) Will LINUX use what's offered or use the space only if required - i.e. does it try to be efficient? 3) When trying to squeeze LINUX into a m/c with several small HDD's I found that a maximum of 4 partitions per drive was allowed. Is there a reason for this? (cant remember every trying to ad more than 3 partitions in the past! DOS or LINUX) So far so good! :-) Adrian ---------- > From: adrian.wells <adrian.wells(a)sidcot.org.uk> > To: SuSE list <suse-linux-uk-schools(a)suse.com> > Subject: [suse-linux-uk-schools] Installing LINUX on SCSI > Date: 26 January 2001 11:45 > > All installations that I have completed so far have been on std IDE boxes, > with few if any probs (apart from Graphics and NIC). > > I have tried to install 6.3 6.4 & 7 of LINUX on a P166 80M ram 2x 8GB SCSI > HDD 2x 4GB SCSI 1x SCSI CD-ROM, all via an Adaptec AHA-2940 (BIOS 1.23) > SCSI card. > > I have loaded the 294x drivers after booting from FDD and then start > installation.

Email server

Dear Suse list Any suggestions for how I might run a "Hotmail" online email type of service from our Linux box. Are there any programs out there already set up to do this sort of thing ? Our school is soon to have a permanent in and out connection so this becomes an attractive option to offer our own pupils and FPs. Best regards Alan Craig PT CDT Aberdeen Grammar School

The advantage of a program which simply looks in ~/Maildir is that it dosn't need the user to either enter or store passwords. They just run the program and it looks at the files. Web and IMAP make more sense, IMHO, where the machine dosn't have access to the relevent files directly (as either ~/Maildir or X:\Maildir, maildir was designed to cope with NFS, it manages just as well with SMB/CIFS). e.g. from home... > If you add maildrop to the mix, you can then also do mail filtering on > delivery, and whats more sqwebmail gives you a web GUI for editing your > mail filters.

Re: [suse-linux-uk-schools] fastest printer sharing?

I presume > you'd be reasonably familiar with your printer configuration tool of choice. If you are only printing from windows, you could also configure a 'raw' printing device, and install the printer drivers on windows as usual. This way you get all the usual bells and wistles at the Windows end, and Linux does nothing but pass anything it gets over the network on to the printer. Linux does not need to support the printer at all in this case. I think you can get Samba to 'serve up' the printer driver to the Windows boxes too - making management of updates/etc easier - but have not done this myself ... Kevin.
