/var/adm/wtmpx: Value too large for defined data type

# cd /var/adm

# /usr/lib/acct/fwtmp < wtmpx > wtmpx.ascii

 

edit wtmpx.ascii by "vi" or "tail" 

 

# /usr/lib/acct/fwtmp -ic < wtmpx.ascii > wtmpx

# rm wtmpx.ascii

 

——————————————————————

 

# cp /var/adm/wtmpx /var/adm/wtmpx.old

# > /var/adm/wtmpx

 

按照这个方法清空了wtmpx文件

 

ksh下

 

# logadm -w wtmpx -c -C 3 -p 1m /var/adm/wtmpx

Where :

 

-w writes an entry in the /etc/logadm.conf file with entry name "wtmpx".

-c is a flag to copy and then truncate the file

-C is the number of copies to keep

-p is the retention period (one month here)

可以限制last保存的时长

 

另外，LINUX下的last文件可在/var/log/下的wtmp文件中找到。
