Perhaps my subject should have been 'kernel compile problem'

Having upgraded my Debian system to 'Testing' I am trying to move to kernel 2.4.18 but before I do that I need to get an iptables firewall set up. With my original 2.2.20 kernel I had used PMFirewall to set up my firewall. Answer a few simple questions and Bingo - one firewall and a perfectly servicable one too. I am trying to use Endoshield in the same way but have recompiled my kernel with the relevant bits included I get the following when depmod is run: depmod: *** Unresolved symbols in /lib/modules/2.4.18/kernel/net/ipv4/netfilter/ip_conntrack.o depmod: *** Unresolved symbols in /lib/modules/2.4.18/kernel/net/ipv4/netfilter/ip_tables.o depmod: *** Unresolved symbols in /lib/modules/2.4.18/kernel/net/ipv4/netfilter/ipt_REJECT.o depmod: *** Unresolved symbols in /lib/modules/2.4.18/kernel/net/ipv4/netfilter/iptable_filter.o depmod: *** Unresolved symbols in /lib/modules/2.4.18/kernel/net/ipv4/netfilter/iptable_mangle.o depmod: *** Unresolved symbols in /lib/modules/2.4.18/kernel/net/ipv4/netfilter/iptable_nat.o I have never had unresolved symbols after compiling a kernel until now. Apart from that the kernel seems to work perfectly well. Barry Samuels

I have compiled kernels many times. Never had this before. Thanks for trying. Barry Samuels

Re: [Alug] MTU & TCP/IP (errata!)

My last info was a little incorrect. My /etc/ppp/options file reads: mtu 576 mru 512 lock Since the MRU needs to be less than the MTU. (essentially MTU- header size). Actually, I have noticed that I connect quicker as well as view pages quicker. If you remember seeing those dreadful adverts for windoze users saying "speed up your modem", this is essentially what those programs do. They also usually nag you with popups as well, though!

Well, as soon as we get a confirmation on the exact date, time and location of the UEA one, I am more than willing to run around the computer shops in Norwich city centre with posters for it. Of course, that doesn't mean they'll AGREE to putting them up, but it's worth a go. I can always use the colour laser printers at work for the posters. ;) Ricardo -- Get your free email from www.linuxmail.org Powered by Outblaze

> > Is there any way to change the default MTU in Linux -SNIP- In response to my own question (for the archives, you see), I edited the /etc/ppp/options file, adding the lines mtu 576 #this is for outgoing connections mru 576 #this is for incoming connections (actually, I didn't add the comments). I used ping to work out the appropriate numbers. Ricardo -- Get your free email from www.linuxmail.org Powered by Outblaze

The script is likely calling for modules, if iptables was compiled in, these modules won't exist. (i.e. may have to modify the script) Ricardo -- Get your free email from www.linuxmail.org Powered by Outblaze

I suspected it would be in the kernel- the discovery method working on ever dial-up connection made would get a little irritating, since it would slow things down initially (as it tested the network path) What is advmss? > But there are unfortunately many networks that don't play nice > with this.

Hi Been lurking for a while now on an old e-mail address but figured it was time to actually come forward and say hello. My names Darren, I live in Essex, 27. I own a medium sized web hosting company, with servers in the US all running Slackware 8, usual stuff PHP/MySQL/Perl/Apache/Sendmail or Qmail PGSQL etc.. We also have servers running Redhat on another network, these are Leased. The other ones are our own equipment, i.e. we are not a reseller as so many "hosting companies are" Just ordered a Rack in Redbus Docklands which should be live by the end of the month. The version of Slackware we use is highly customised, I have found this distro to be great as a server rather then a desktop OS. Everything about the way it boots to the way we run MySQL is "different" which is nice but can also be a nightmare sometime :) I just order SuSE to give that a go as a office desktop OS, tried Deb but didn't really get on with it. I love Linux, not even close to understanding everything about it but I can handle everytning I ever need to do with it. I have a guy that writes PureFTPD working for me on a part time basis and he knows more then I could ever hope to know. His also a hardcore programmer, his working with the PHP Dev team atm for upgrades to the new version etc.. Nice guy to have on board. Here to mix with a few like minded people and learn a thing or two. Regards Darren
