执行sftp命令时报Received message too long 1114795883

      操作系统:suse 10 sp2 64bit
      fly007用户的SHELL为:csh
1、同事反映,使用sftp登入服务器时,报Received message too long 1114795883错误:

fly007.example.com:~ # sftp [email protected]
Connecting to 192.168.1.90...
Password:
Received message too long 1114795883

2、只有fly007用户存在这个问题,怀疑是fly007用户的环境设置问题,su �C fly007没有任何的输出,

如果.cshrc,.bashrc,.profile文件中有一些cat,echo的输出,可能会导致这个问题,这是度娘的回复,

测试了下,确实是会出现这个问题,如下所示:

fly007.example.com:~ # su - csh
haha
fly007.example.com> echo $SHELL
/usr/bin/csh
fly007.example.com> cat .cshrc
echo "haha"
fly007.example.com> exit
logout
fly007.example.com:~ # sftp [email protected]
Connecting to 192.168.1.90...
Password:
Received message too long 1751214177

3、问题基本可以确定在fly007的环境设置上是有问题的,因为sftp是ssh的子服务,scp也是,ssh是可

以正常登入的,且不报错的,su也是可以正常切换的,那么scp呢

fly007.example.com:~ # scp 1.txt [email protected]:/home/fly007
Password:
stty: standard input: Invalid argument
1.  txt                  100%

4、问题基本可以确定了,设置的stty环境变量有问题

fly007.example.com:~ # su - fly007
fly007.example.com>echo $SHELL
/usr/bin/csh
fly007.example.com>cat .cshrc | grep stty
stty erase "^H" kill "^U" intr "^C" eof "^D" susp "^Z" hupcl ixon ixoff tabs

5、注释stty环境变量

fly007.example.com>cat .cshrc | grep stty
#stty erase "^H" kill "^U" intr "^C" eof "^D" susp "^Z" hupcl ixon ixoff tabs

6、执行scp和sftp,不再报错,问题解决

fly007.example.com:~ # scp 1.txt [email protected]:/home/fly007
Password:
1.txt                                                     100%    0     0.0KB/s   00:00
fly007.example.com:~ # sftp [email protected]
Connecting to 192.168.1.90...
