Why does the installation bomb out with a "Signal 8" error ?
Reason :- :Under SCO OpenServer 5.0.5 this is mainly a symptom of a memory problem. In the "SCO OpenServer 5.0.5 Release Notes" booklet, SCO states that your system must have at least 32MB of RAM to succesfully install OpenServer. If you have less, the following message is likely to appear on the screen: Reading from install source 10 Kb/ramFs/extractProd/extractAll terminated by signal 8
Solutions:- Typing the following at the boot prompt:
Sir I am changed ip address in SCO unix (LIC)by going to scoadmin and then to networking. I changed the IP address sucessfully but its not doing ftp or telnet to server or other pc in the network. it gives authentication failed. Please guide.
Problem : To add swap space on an already installed system:
Solution : 1. Log in as root.
2. Use the dd(1M) command to create a file equivalent in size to the amount of swap space you are adding:
dd if=/dev/null of=file oseek=num bs=blocksize
This example creates a 200MB file on the default vxfs root filesystem:
dd if=/dev/null of=/outputfile oseek=200 bs=1024k
3. Use a text editor to edit the /etc/swaptab file and add information for device_name, start_offset, and size:
file 0 -
The device_name is the name of the file you created using the dd command, the start_offset is ``0'', and the minus sign indicates that the entire file is to be used as the size of the new swap space.
4. Reboot the system to make the new swap space available for use.

A DAT tape written on one model of a SCSI DAT drive cannot be read on a different model of SCSI DAT tape drive.
Solution
SCSI DAT tape drives are often not interchangeable when read on a different make/model of drive than the tape was written on. There are two reasons for this:
Blocking Factor ===============
DAT tape drives use either a variable or fixed block size. Each drive has a default blocking factor that is determined by the drive's hardware/firmware. It is not related to the blocking factor used by tar or cpio. Presently, the SCO tape drivers use the drive's default block size. There is no way to change this block size in the software.
For example, an Archive DAT tape drive uses the blocking factor of 1k bytes per block. The Hewlett-Packard DAT uses the blocking factor of 2k bytes per block.A Hewlett-Packard DAT cannot read a tape written on an Archive DAT.
Data Compression ================
Data compression is performed at the firmware/hardware level. Some Hewlett-Packard DAT drives and the Compaq DAT drives do data compression. There is no standard for data compression and the tape drive manufacturers use different data compression formats. Thus, it is unlikely for two models of DAT drives that use data compression to be able to read each other's tapes.
During system start up I see slink errors indicating my network card failed initialization. Checking the /tmp/inet.start log also shows that the failure was related to "dlbind: BAD SAP"
When checking `ifconfig -a` the network card is not listed.
CAUSE:
This message indicates that the dlpi driver layer could not determine a valid media type for the device, which could be caused by either a hardware problem with the network card or some problem with the NIC driver installation.
Solution
As a first step, try removing and re-adding the network card driver. This has been reported to correct this problem.
See the exact driver instructions on how to "pkgrm" the existing driver and add the new one using "pkgadd" from the latest driver available from http://www.sco.com/support/download.html.
It is recommended to remove the entry for the NIC in "netcfg" first.
As a second step, try re-seating the card in a different slot.
If problems persist try replacing the card itself.
Problem Reported By : Mr Deepak (From KJ Industries Gwaliar) Problem : At the time of login in dumb terminal its give error on screen Terminal ttyxx is disable – see account administrator. Solution : To allow the terminal to be accessed, the super user must unlock the user’s account through the SCO administrator utility # scoadmin
Then select System-> Terminal Manager -> Unlock
Type the name of terminal to be unlocked, or press f3 for the list & select the terminal you want to unlock
A confirm change window will appear asking
Are u sure u want to take this action?
Select yes & now users will be able to log on that terminal
1. Use the format command to create two formatted diskettes. For example, this command creates a formatted, 1.44MB diskette in the primary diskette drive:
format -v /dev/rdsk/f03ht
2. Label the diskettes with the name of the system, date created, and their name and number. For example -
mymachine mymachine 9 September 1997 9 September 1997 Emergency Recovery Emergency Recovery Diskette 1 Diskette 2
NOTE- Emergency recovery disks are customized for a particular system and only work on that system.
3. Switch from the graphical environment to the system console, by pressing Ctrl Alt Esc. Log in to the system console as root.
4. Ensure that /var is mounted.
5. Make sure there are no active users on the system. Enter:
who
6. If root is the only user logged in, bring the system to single-user mode with this command:
shutdown -y -g0 -i1
If other users are listed, bring the system to single-user mode with this command:
shutdown -y -g300 -i1
The -g300 flag in this command allows users 5 minutes (300 seconds) to close their files and log out. A broadcast message from root provides warnings that the system is coming down.
7. After the system enters single-user mode, determine in which filesystem you will create the recovery media. The filesystem must contain at least 30 MB of free space.
To determine which filesystems have enough space, enter:
/sbin/dfspace
For example, you might see:
/ : Disk space: 195.10 MB of 429.00 MB available (45.48%) /stand : Disk space: 5.82 MB of 9.99 MB available (58.28%) /home : Disk space: 238.86 MB of 479.00 MB available (49.87%) /tmp : Disk space: 7.98 MB of 8.00 MB available (99.85%) /var/tmp : Disk space: 9.99 MB of 8.99 MB available (90.00%)
In this example, only the root (/) and /home filesystems have enough space to be used in creating the emergency recovery media.
8. Enter:
/sbin/emergency_disk -d pathname diskette
pathname is the filesystem you selected. diskette is the diskette drive where you will insert the diskette (either diskette1 or diskette2).
The following example creates an emergency recovery diskette on the first diskette drive, using the /home filesystem as its working directory:
/sbin/emergency_disk -d /home diskette1
9. When prompted, insert the first formatted disk into the appropriate diskette drive.
Creating each emergency recovery disk takes about fifteen minutes.
10. When prompted, remove the first diskette, insert the second diskette and press Enter.
11. When prompted, remove the diskette from the diskette drive.
Store the emergency recovery disks in a secure location.

Sir
It is Sco Unixware.
Hi Pankaj,
Firstly check the network connectivity through following steps:
# Scoadmin
# go to networking option
# view the ip setting
After then create new user account using account manager (Sco admin),
You can’t use telnet with root account. You have to create other one
Please let me know if you face any other problem

Problem : To add swap space on an already installed system:
Solution : 1. Log in as root.
2. Use the dd(1M) command to create a file equivalent in size to the amount of swap space you are adding:
dd if=/dev/null of=file oseek=num bs=blocksize
This example creates a 200MB file on the default vxfs root filesystem:
dd if=/dev/null of=/outputfile oseek=200 bs=1024k
3. Use a text editor to edit the /etc/swaptab file and add information for device_name, start_offset, and size:
file 0 -
The device_name is the name of the file you created using the dd command, the start_offset is ``0'', and the minus sign indicates that the entire file is to be used as the size of the new swap space.

Creating emergency recovery diskettes
To create emergency recovery disks:
1. Use the format command to create two formatted diskettes. For example, this command creates a formatted, 1.44MB diskette in the primary diskette drive:
format -v /dev/rdsk/f03ht
2. Label the diskettes with the name of the system, date created, and their name and number. For example -
mymachine mymachine
9 September 1997 9 September 1997
Emergency Recovery Emergency Recovery
Diskette 1 Diskette 2
NOTE- Emergency recovery disks are customized for a particular system and only work on that system.
3. Switch from the graphical environment to the system console, by pressing Ctrl Alt Esc. Log in to the system console as root.
4. Ensure that /var is mounted.
5. Make sure there are no active users on the system. Enter:
who
6. If root is the only user logged in, bring the system to single-user mode with this command:
shutdown -y -g0 -i1
If other users are listed, bring the system to single-user mode with this command:
shutdown -y -g300 -i1
The -g300 flag in this command allows users 5 minutes (300 seconds) to close their files and log out. A broadcast message from root provides warnings that the system is coming down.
7. After the system enters single-user mode, determine in which filesystem you will create the recovery media. The filesystem must contain at least 30 MB of free space.
To determine which filesystems have enough space, enter:
/sbin/dfspace
For example, you might see:
/ : Disk space: 195.10 MB of 429.00 MB available (45.48%)
/stand : Disk space: 5.82 MB of 9.99 MB available (58.28%)
/home : Disk space: 238.86 MB of 479.00 MB available (49.87%)
/tmp : Disk space: 7.98 MB of 8.00 MB available (99.85%)
/var/tmp : Disk space: 9.99 MB of 8.99 MB available (90.00%)
In this example, only the root (/) and /home filesystems have enough space to be used in creating the emergency recovery media.
8. Enter:
/sbin/emergency_disk -d pathname diskette
pathname is the filesystem you selected. diskette is the diskette drive where you will insert the diskette (either diskette1 or diskette2).
The following example creates an emergency recovery diskette on the first diskette drive, using the /home filesystem as its working directory:
/sbin/emergency_disk -d /home diskette1
9. When prompted, insert the first formatted disk into the appropriate diskette drive.
Creating each emergency recovery disk takes about fifteen minutes.
10. When prompted, remove the first diskette, insert the second diskette and press Enter.
11. When prompted, remove the diskette from the diskette drive.
Store the emergency recovery disks in a secure location.

Solution :During the tape configuration, you are asked if you wish to change the default tape boot string.You can choose to leave the defaultsetting and quit, but if you enter a new string which is incorrect,then the following message occurs:
WARNING: SCSI boot option(s) ignore
The boot string gets written in the /etc/default/boot file.
