Date: Mon, 22 Jan 2001 06:29:10 GMT
I compiled kernel 2.4.0 recently, with support for SBLive soundcard
as a module. I can play sound, but no midi. midi softwares told me that
/dev/sequencer cannot be open.
Could anyone tell me how to config this (my system is redhat 7).
Thank you.

It is customary to simply run e2fsck regularly to make sure the file
system remains intact. Now with modern media the occurrence of bad
sectors is quite rare, most discs just die, they don't fail gracefully,
but still the practice remains to regularly check them, as it is always
good to be thorough.
Since the file system shouldn't be mounted when cheched it is done
as part of the boot process before the discs are mounted. Now when to
check? Everytime? Rather not, since it can be a lengthy process for
larger discs. Ask interactively at boot? No good when doing remote
administration. Keep a counter and run a check every so often is the
chosen solution. The most common choice is to check every #nth time the
filesystem is mounted. Some people use a chosen number of days instead,
especially when the system stays up long, and a maximal mount count
won't be reached in years.
So to make that possible the ext2 filesystem has information of when
it was last checked with e2fsck, how often it has been mounted since, and
more. When the "maximal mount count" has been reached the system
automagically runs e2fsck, just as it is run when the filesystem was not
cleanly unmounted.
You can check the current settings with :
/sbin/tune2fs -l /dev/hda5
and change them (after unmounting the filesystem and reading the man
page as well) with tune2fs as well.
In other words things are just as they should be.

I have kppp configured correctly, both as root and as a normal user. It
works fine under root, but it says "Logging on to Network" and then croaks.
The log file doesn't say anything. Wondering if anyone else had this
problem with SuSE 7.0.

Simply do a network install. Downloading a 650 MB iso image will take
more time as downloading only the files you need. The problem is getting
it right the first time around ;-) So if downloading isn't the problem, decide
a distribution, go to their "dos-utils" section get the readme,
rawrite.exe and the correct boot disc. Use rawrite to write the boot
disc image to a floppy, use that to boot the system and them do a
network install. Will only work reasonably well if you have a fast
internet connection. In RedHats case:
Mirrors/ftp.redhat.com/redhat/redhat-7.0/i386/en/dosutils/rawrite.exe
Mirrors/ftp.redhat.com/redhat/redhat-7.0/i386/en/images/bootnet.img
Mirrors/ftp.redhat.com/redhat/redhat-7.0/i386/en/images/drivers.img
Mirrors/ftp.redhat.com/redhat/redhat-7.0/i386/en/images/pcmcia.img (if
needed)
Otherwise go to cheapbytes.com (or others) and order a cd. That should
cost not too much, and will allow you to get a cd and save yourself the
agony of downloading 500 MB just to mess things up and having to get it
again.
IMHO The best would be to buy a decent book (search the linux groups for
recommendations) with a cd with redhat, suse, or debian included. That
will give you also some information about what to do once everything is
up and running. Most boxed distributions only contain an installation
manual, so your better of, buying a linux book (with cd) that covers more
then just installation. Most better assorted bookstores now have several
linux books on stock, so have a look there, make sure the cd is recent
(fi redhat 6.0 would be too old to support newer hardware, and has too
many outdated insecure software). Something like learning debian
GNU/linux, the $FLAVOUR linux bible, or $FLAVOUR Unleashed. O'Reilly is
traditionally the most often refered to publisher for opensource
manuals, but I don't know what they would have in stock now.

I have wvdial. I executed it and it worked once, but I executed it again and it
(in part) reported the following:
Warning: Could not modify /etc/ppp/pap-secrets: Permission denied
PAP (Password Authentication Protocol) may be flaky.
Warning: Could not modify /etc/ppp/chap-secrets: Permission denied
CHAP (Challenge Handshake) may be flaky.
Starting pppd...
PPP daemon has died! (exit code = 2)
Disconnecting...
pppd error! Look at files in /var/log for an explanation.
It dials the modem and connects but aborts once it has logged in. I set
permissions on pap-secrets and chap-secrets to -rwxrwx--- and tried again,
same results. I looked in recently changed logs in /var/log, but I did not find
any additional error information.

Well on my 6.2 system the permissions for both pap-secrets and
chap-secrets is 600 and are owned by "root.daemon" but they may be
different for Debian.
man wvdial might help since I am not familiar with Debian.

Please stop spreading this misinformation. The System.map file
is not needed for anything except debugging kernels (it's a longer
version of /proc/ksyms). Since you don't know what it is for

Go to www.linuxdoc.org and read IP-Masquerade Howto. I just got mine working.
Then read DNS howto and setup caching dns, its great for dialup, cable, adsl.
You should probably read the PPP howto first to automate your pppd.

Installing the RH updates may help save you, but in my case before the RH6.2
system was fully built (no updates, no data, no firewall etc) I was hacked,
this "Person" installed a cron job on my system, created a new user account
etc. But left behind was his .bash_history file and all the system logs,
oops!
Cleaned this junk, installed my firewall, blocked all contact from the ISP
this "person" was using, sent complaints to both ISP's with the source IP and
full analysis of the what was done etc.
Now with a new IP address, firewall running, automatic log checks etc.
There are more updates that the ones you list, its a good idea to install all
that are relivent to your setup.
for RH6.2

I can't tell what you did wrong (perhaps just bad LILO options?)
but 07:07 is NOT a HDD partition.
You can force a boot by supplying the correct parameters.
At the lilo prompt:
linux root=/dev/hdXXXX
where /dev/hdXXXX should be the partition where your root FS resides.
After you booted, check /etc/lilo.conf first.
Pay special attention to the root= option.
If there's nothing wrong there, maybe you need rdev??
try `man rdev`

I am not sure I understand your question entirely.
Mainly because I can't do much with c/d/e/f
Show your current partitiontable, and then perhaps I can help you.

Nope. It fails to mount the root FS.
Because you gave wrong options I suppose
When you get to LILO, try "linux root=/dev/hdc5"
And it will boot.
Now correct the problem (I suppose in lilo.conf, but I can't be sure)
