My 2.2.16 SuSE system doesn't have that directory structure, but if you go
to a SuSE 2.4.7 everything is there.

Jay,
A CTC is used to connect Linux to TCP/IP on VM. Since that's the only way
I
can gain access (Telnet) to the Linux server via TCP/IP, I'm as sure as I
can be that the CTC driver -is- loaded. I'm also certain that the named
file and directories do not exist.
linux016:~ # lsmod
Module Size Used by
ctc 21220 1 (autoclean)
linux016:~ # cd /proc
linux016:/proc # cd net
linux016:/proc/net # ls
. dev igmp ip_mr_cache netstat rpc sockstat udp
.. dev_mcast ip_fwchains ip_mr_vif raw rt_cache tcp unix
arp dev_stat ip_fwnames netlink route snmp tr_rif
linux016:/proc/net #
I'll mention that I'm at the 2.2.16 level of SuSE 7.0 GA. Are you seeing
different results with your system? If so, what distribution are you
using?
I personally haven't yet worked with the 2.4 kernel and if the CTC driver
works differently at that level, I'd like to hear that. I'll mention again
that the quote from the manual was for the 2.2.16 level of code. Again,
perhaps, we've missed some service?
Thanks for your comments. The more I check the more I learn about all this
stuff! ;-)

The file is not there because the driver is not yet loaded. You have to
load the driver first before you can change the buffersize. All the
appropriate /proc stuff gets created after the driver loads.

Please respond to
Linux on 390 Port
The IBM "Linux for S/390 Device Drivers and Installation Commands"
document, dated 18 July 2001, in Chapter Seven, "Linux for S/390 CTC/ESCON
Device Driver", has Usage Note 2 under "Preparing the Connection" which
reads:
Definitions on the remote side
Set up the TCP/IP on the remote side, as described in the reference
manuals.
This will vary depending on which operating system is used on the remote
side.
Note: It is important that you have IOBUFFERSIZE 32678 defined because
the
LINUX for S/390 CTC driver works with 32k internally. This is
configurable
for each device by writing the value to the buffersize file for that
device
(proc/net/ctc/<devicename>/buffersize ), for example
echo 32768 >/proc/net/ctc/ctc0/buffersize
I'm not sure how this is accomplished. Logging on as root and issuing the
command doesn't work. Here's what I get:
LINUXWPS:/proc # echo 32768 >/proc/net/ctc/ctc0/buffersize
bash: /proc/net/ctc/ctc0/buffersize: No such file or directory
What is the correct technique for creating the appropriate directories and
file?
